C-1. 2040 Comprehensive Plan Staff Report 1 Y —/ � w 9 S CITY OF ClIANHASSEN Chanhassen is a Community for Life-Providing for Today and Planning for Tomorrow NH k MEMORANDUM TO: Planning Commission FROM: Kate Aanenson,AICP, Community Development Director DATE: October 17, 2017 SUBJ: 2040 Comprehensive Plan BACKGROUND The Planning Commission held discussions this year to review the draft 2040 Comprehensive Plan (Plan). The Planning Commission reviewed the following: April 4, 2017 Overview of Comprehensive Plan. April 18, 12017 Sewer, Transportation, and Water July18, 2017 Housing, Land Use, Sewer, Water and Parks & Open Space August 1, 2017 Natural Resources August 15, 2017 Water Resources October 3, 2017 Surface Water, Goals & Policies, Implementation and CIP City Council approved the Plan for jurisdictional review on October 9, 2017. The Plan is being distributed to other jurisdictions on October 20, 2017 and the comment period is open until April 20, 2018 for jurisdictional review. Following that date,the Planning Commission will review the Plan based on comments received during the review period,jurisdiction comments, the city's written responses to any comments and make a recommendation to City Council for adoption of the Plan. City Council can then approve the Plan contingent upon submitting the Plan to the Metropolitan Council for their review and finding the plan consistent with the Metropolitan System Plans. Only after the Metropolitan Council finds the plan consistent with the regional plan can the city's 2040 Comprehensive Plan go into effect. The 2040 Comprehensive Plan consists of the following chapters: Chapter 1: Introduction Chapter 2: Land Use Chapter 3: Housing Chapter 4: Natural Resources Chapter 5: Parks and Trails PH 952.227.1100• www.ci.chanhassen.mn.us• FX 952.227.1110 7700 MARKET BOULEVARD • PO BOX 147 • CHANHASSEN • MINNESOTA 55317 Planning Commission October 17, 2017 2040 Comprehensive Plan Page 2 of 20 Chapter 6: Transportation Chapter 7: Sewer Chapter 8: Water Chapter 9: Surface Water Chapter 10: Capital Improvements and Implementation The reason for this public hearing is to initiate the six month jurisdictional review process by allowing individuals to comment on the draft 2040 Comprehensive Plan and permit the Planning Commission to review, ask questions, comment and provide direction on creating the final 2040 Comprehensive Plan document that will be adopted in 2018. DISCUSSION INTRODUCTION The introduction provides a general overview and framework for the City of Chanhassen Comprehensive Plan. This chapter addresses the city's vision as it moves forward. LAND USE The goal of the city is to create a mixture of land uses that provides a high quality of life and a reliable tax base. We have a very successful downtown and there is additional opportunity for retail with the potential development of a mixed use development at Highway 212 and Powers Boulevard as well as part of the mixed used development at Flying Cloud Drive and Highway 101,which was re-guided in 2015 as part of the CSAH 61 corridor study. Based on staff analysis, there is a sufficient diversity of residential land uses to accommodate housing growth in the community. 2030 2040 Land Use Plan Land Use Plan Change 2030-2040 Land Use Acres Percent Acres 1 Percent Acres Commercial 328 2.2% 328 2.2% - Office/Industrial 883 6.0% 843 5.7% (40) Office 339 2.3% 277 1.9% J62) Parks&Open Space 1,410 9.6% 1,518 10.3% 108 Public/Semi-Public 1,204 8.2% 1,204 8.2% - Residential Large Lot - 971 6.6% 948 6.4% �23� -Residential Low Density 4,707 31.9% 4,597 31.1% (110) Residential Medium Density 400 2.7% 499 3.4% 99 Residential High Density 218 1.5%0 218 1.5% - Mixed Use 115 0.8% 143 1.0% 28 Undevelopable 4,185 28.4% 4,185 1 28.4% - TOTAL 14,760 14,760 - Undevelopable Lakes, Floodplain, Rivers, Streams 2,059 2,059 Road Right-of-Way 1,244 1,244 Agriculture 882 882 TOTAL 4,185 4,185 Planning Commission October 17, 2017 2040 Comprehensive Plan Page 3 of 20 Map Amendments The city has received two requests for consideration of designated land use as a part of the update to the 2040 Comprehensive Plan. Staff is also proposing one land use amendment. 1. Request from Erhart Family Tim and Diane Erhart are requesting two issues. One is removal of an area from the Bluff Creek Overlay District, approximately 3.2 acres which is currently guided low density. The second request is for a dual guiding of the property for High Density Residential and Office. Following is analysis for your consideration. Amendment Request as prepared by Tim Erhart: After further consideration in addition to our recent request to modify the Bluff Creek Overlay District Map as it relates to land east of Powers Blvd we additionally request a change to type of use permitted. We request that the area adjacent to Powers Blvd be dual guided. Currently the area is guided office/industrial only. We believe that an alternative good use would be high density residential. The area is well served by the nearby TH#212 intersection, accessed via Powers Blvd. We understand that a bus station will be constructed in the immediate area as well. A residential use would allow residents use of the extensive trail system (planned) in the area as well as convenient access to Fox Woods Preserve. Moreover, residents would have access to Bandimere Park by a nature trail. We also believe that offices would also allow use of the outdoor activity provided however it could be that high density residential may even provide more opportunities for people to enjoy. History of the site: • Bluff Creek Overlay District created in 1998(See attached Overlay District code) • 3 acres re-guided with the 2008 Comprehensive Plan from Low Density to Office • Land use amendment to allow 7 additional acres medical office. • A medical office plan was given site plan approval in 2009 but was never constructed. Erhart Acres gross Land Use- Land Use High Denisty Existing land use Requested land Office 8-16 units an acre use potential sgft. potential units 9.5 acres 9.5 +3.2= 12.7 166,000 sq.ft. 101 -203 units I Planning Commission October 17, 2017 2040 Comprehensive Plan Page 4 of 20 Remove Erhart Property from Bluff Creek Overlay District. Purpose of First Request: The Introductory sentence of the BCOD refers to the Bluff Creek Watershed Area. Starting with the second sentence and all references thereafter the term Bluff Creek corridor is employed. IT is clear from a reading of the BCOD ordinance that the intent is to apply development restrictions to "land areas abutting and in the vicinity of the (Bluff Creek) watercourse and its tributaries" (sec. 20-1552). To emphasize the focus on proximity, the word corridor is used four times in the Purposes section of the ordinance. The Ordinance also purposed to "Foster the creation of a greenway connecting Lake Minnewashta Regional park and the Minnesota River Valley". In addition, other sentences are included that clearly indicated that this ordinance was intended to be applied to the corridor(and some cases a tributary) but not all lands in the Bluff Creek watershed or lands at a distance from Bluff Creek. The Bluff Creek watercourse lies nearly one quarter mile from the nearest point of our property, which demonstrates that our property is not "in the vicinity of Bluff Creek". Second, a four lane highway (Powers Blvd)separates our property from the Bluff Creek Corridor. Third, there are no tributaries of Bluff Creek on our property. In fact, there are not tributaries east of Powers Blvd. All water leaving the area east of Powers Blvd flows through pipes and road ditches, all man-made devices. Conclusion: Having our land included in the BCOD is inconsistent with the stated purpose and intent of BCOD and therefore is a misapplication of the ordinance. Therefore, we request that our land be removed from the BCOD. Second Request: If the city cannot agree to remove our land from the BCOD then: 1. Adjust the Primary Zone line to a position where one can clearly distinguish why the line would be placed in such a location. In other words, there would be one or more features of the land that differentiate one side of the line from the other side. This is in contrast to the arbitrary location of the line as it is now and where no one can differentiate one side from the other. 2. Adjust the BCOD boundary lines such that only those areas with permanent natural features such as bluffs, wetlands, and buffers between conflicting land uses are included within the primary and secondary zone. 3. Guide the entire 12.7 acres within the proposed BCOD limits illustrated on the maps to office, industrial or institutional use. 4. Guide the 1.8 acres directly south of New Street for public use and relocated storm pond. Planning Commission October 17, 2017 2040 Comprehensive Plan Page 5 of 20 Purpose of Second Request: 1. Amending the current plan and BCOD limits will allow the best use of the 12.7 acre area site (titled Fox Office Campus). Its location and direct access to the TH#212/Powers Blvd interchange makes this area ideal for office, industrial, or institutional use. 2. Convert the 3.2 acre area currently guided residential to office, industrial or institutional use as this area can only be accessed through the area already guided for such use. 3. Retain the existing natural area (RIM pond and north/south wooded hill) which serves as a buffer between future residential development to the east and the planned office park to the west. 4. Maintain the existing(private) trail connection between a future trail head at New Street (see map) and Fox Woods Preserve. This trail runs through the center of the wooded buffer area. Once development occurs this trail will be designated for public use. 5. Provide space for community facilities including a trail head and trail head parking at Powers Blvd directly south of New Street. 6. Allow space for the relocation of the existing storm pond to the south side of the New Street (map). 7. Provide space for a planned lift station intended to serve the area south of Pioneer Trial 8. Provide parking and service access to the lift station's stationary equipment. Bluff Creek Overlay District Knowing where to apply the development restriction of the Bluff Creek Overlay District Ordinance (BCOD) to a property depends primarily on what is included in the Primary and Secondary Zone and what is not. The ordinance is then applied to all areas of property which lie within those zones. This specifically determines how the property within the BCOD can be used, what areas are "undevelopable"vs. "developable", what value the property is to the current owner and future users, and what tax generation capacity will result for the city when developed. Which such significant impact, it is critical that the boundary be laid down with great care and thoughtfulness and with some sense of consistency based on other similar lands within the city. Most importantly, there must be scientific analysis applied(inferred but not described in the ordinance) to objectively determine the boundaries of the BCOD. At the time the BCOD ordinance was adopted, the Primary Zone boundary was established generally through the use of aerial photographs as no "on the ground"survey and/or data was available for scientifically determining the limits of the zone. The intent(Section 20-1555 Boundary delineation) was that as properties come up for development the landowner was to provide field data to assist the city in making a determination of the line's final location. While this process seems to be well intended, the ordinance, while describing the kind of data requested, is basically silent on how to use the data to establish the actual location of the delineating line (the one exception is sec 20-1551 which deals with slopes specifically stating that area exceeding 25%slope should be preserved). No additional guidance or process is given that would allow one or more individuals, by applying the ordinance's guidelines, to make Planning Commission October 17, 2017 2040 Comprehensive Plan Page 6 of 20 similar and consistent determinations of the boundary line's location. It is our view that it should be inherent in any standard that two reasonably experienced people applying the same standard would come up with essentially the same conclusion. This is hardly the case with the BCOD. As a result, this lack of definition leaves it up to the sole discretion of the city staff as to where the BCOD is established. This arbitrary process could lead to many substantial disagreement, as I believe it has in the past. We submit that there must be some "standard"established, which when applied results in a consistent determination as to the location of the BCOD boundary lines. It is also our view that the primary criteria for determining this boundary should be permanent features such as topography and existing wetlands rather than plant cover, a fence or the edge of a field. Nor should it be based on an existing road or previous use such as agriculture or a building site. These things are most often created by human activity and change over time. Moreover, employing tree coverage is problematic as it also changes over time and penalizes the landowner who cultivates the property for agricultural production would be able to freely develop the property as there would be no tree cover due to his actions (and subsequently no BCOD). I believe this is unfair and contrary to the spirit of the ordinance. That said, where existing tree cover combine with a specific typographic feature forms a buffer between two conflicting land uses, tree cover may be considered a factor in establishing the line's location. Trees simply by themselves are not a reason to include land in the Bluff Creek Overlay District. Typography and wetlands are much more permanent land features and better define what an appropriate use of the land is for generations to come. Use of topography and wetlands allow for more obvious and conclusive locations of such boundaries. Areas where level or gently slope abruptly change to a steep and prolonged slope are obvious points of separation and should be applied as logical boundary lines as city ordinances are already established such definitions in code. 4 Obvious point of delineation Level or gentle ( . Slope greater than 25% sloping terrain Wetland boundaries are established easily through surveying, something that is already required of every development and should be used to establish boundary line locations as well. We submit that these two criteria (extensive slopes and wetlands)should be the dominant factors used to establish the boundary line locations for this application of the BCOD. Neither the original location of the primary line (generated by aerial photos) nor the adjusted line (Fairview Planning Commission October 17,2017 2040 Comprehensive Plan Page 7 of 20 Clinic project) demonstrate any topographic or wetland features that would distinguish one side from the other. We therefore submit a proposed new location (described on the enclosed maps and below) which demonstrates and obvious location for the Primary Zone boundary. This location clearly exhibits a natural boundary condition where measureable difference exists between what is "inside"the primary zone and what is "outside". This proposed line is located where terrain changes abruptly from a rolling terrain to a steep extended slope.

The area in question lies directly adjacent to the Interstate 212/Powers Blvd interchange which includes excellent access to the intersection. The area also exhibits great view from the east bound traffic on TH 21. This makes the area ideally suited for office or industrial or institutional use. 2. It provides a beautiful setting for users as they are surrounded on three sides by park land. 3. We believe the current BCOD boundary line shown on the current city mapping for the area is unscientific and arbitrary and should be revised to comply with some reasonable standard or at least exhibit obviousness as to why it is located where it is. Planning Commission October 17, 2017 2040 Comprehensive Plan Page 8 of 20 4. The 3.2 acre area now guided residential is adjacent to the 9.5 acres guided office/industrial. The only access to the 3.2 acre area is through the 9.5 acre area and in our view should be guided for office/industrial and/or institutional as well. Moreover, the area is rather noisy due to traffic from TH#212 making it undesirable for residential use. 5. The 3.2 acres identified on the enclosed map represents an ideal location for a multi- story office building and its required parking area. It adjoins the 9.5 acre parcel guided office/industrial and offers a unique site line from eastbound TH 212 traffic. 6. Allows the construction of office space similar in size to Fairview but moved further to the north and east. This provides for greater separation of uses between the large lot residential area to the south. This movement also eliminates the requirement for removal of part of the steep hill which would also then require the construction of a long 12ft high retaining wall(included in the Fairview plan). Lastly it also eliminates the need to build a parking ramp as approved with the Fairview site as adequate space for surface parking is made available with the addition of the 3.2 acres. 7. The 1.8 acres south of the new street would be used for the trail head leading to Fox Woods Preserve, trail head parking, the relocation of the existing storm pond and a planned sewer lift station. The proposed trail head parking can also serve as access to the lift station. 8. It appears that currently the city intends to use this 3.2 acres as additional park land rather than use the land for its best suited purpose. Even without the 3.2 acres in question, approximately 52.5%of the 360 acres located in the vicinity is already designated as open space and is intended to be used by the public as park or wetland. Addition another 3.2 acres of highly developable and potentially tax generating property to an already expansive natural area will add little noticeable value. 9. The plan shown includes a trail connection to Fox Preserve at two points, starting from the trail head at New Street. This route is completely wooded and overlooks the five acre Rim pond to the east and is screened by threes from the proposed office and parking area to the west. It also contains a smaller pond between the "Y"of the trail on the north end. The development of the 3.2 acres as office/industrial will have no negative impact on this trail connection and its amenities. In fact, such a development can easily include internal connections to the Fox Preserve and area trail system. Including the 3.2 acres as park does not in any way add to the already great experience that this trail provides. 10. Lastly the majority of the 3.2 acre area in question is currently used for agriculture as is a majority of the 9.7 acres already guided office/industrial. This allows easy transition from the current use to office, industrial or institutional use.

",- a _...,. f 47 As can be seen, this area contributes to Bluff Creek. At one time, this area drained overland to Bluff Creek. With urban development, the drainage has been confined in certain areas to pipes and culverts. The drainage pattern on top of the bluff takes local drainage and directs it west towards Powers Boulevard. It also serves as the EOF for the large water body immediately east of the wooded area. Lastly, there is a mitigation area located northerly on the property. Planning Commission October 17, 2017 2040 Comprehensive Plan Page 10 of 20 01111k/.. , • ' Part of the discussion should be about the effects of urbanization on channel characteristics and flow hydraulics. As the area tributary to Bluff Creek is converted from prairie and woodland conditions to urbanized conditions, the following occurs: 1. Base flow is decreased which leads to a failure to support aquatic vertebrates. 2. The flashiness of the flows increase as water is directed to the creek faster than under natural conditions. 3. The duration of the elevated flows is increased. Even with the installation of detention ponds, it still leads to a longer duration of peak flows even if the peak flow is decreased from an urbanized condition without ponds. 4. All of this leads to increased scouring,head cutting, escarpment formation and sediment loading and deposition. 5. This increased sediment load falls out of suspension downstream and leads to an embedded condition meaning there is a diminished fish habitat as the small riffles formed in the cobbled substrate disappear. This also leads to an increase in water temperature and a decrease in transitivity of light and reduced plant and plankton production. It is for this reason that we look at the entire watershed and not just that which is immediately adjacent to Bluff Creek. To facilitate the preservation of the natural resources on this property, the city proposed the dedication of a conservation easement over the primary zone north of the proposed access road and east of the office building.

The primary and secondary zones include land that is generally defined in this ordinance and in the Bluff Creek Watershed Natural Resources Management Plan. Boundaries as established by officially adopted city maps shall be prima facie evidence of the location and type of watershed zone. The official maps shall be developed and maintained by the planning department. The applicant shall provide appropriate technical information, including but not limited to a topographical survey, flora and fauna survey and soil data deemed necessary for the city to determine the exact watershed zone boundary. The community development director shall make a determination to maintain the officially designated watershed zone boundary or if the boundaries need to be corrected on city plans and maps based upon the data that is supplied.Data for watershed zone delineation shall be generated and provided by a qualified professional specializing in watershed management, environmental science or other related profession. The applicant may appeal the community development director's determination of the watershed zone boundary and type to the city council. (Emphasis added) Staff response to Erhart land use amendment request: 1. Taking 3.2 acre out of the Bluff Creek overlay district is premature as with the recent Avienda request. City code specifies the requirements for revising the boundary. The applicant withdrew Planning Commission October 17,2017 2040 Comprehensive Plan Page 12 of 20 their request and will make a request as part of a site plan review. This option would be a variance request to the code. 2. Duel guiding 9.9 - 12.7 acres to High Density or Office would permits up to 112-203 units. Based on the housing study we have sufficient land guided for high density. 2.

In its current state the nursery brings an industrial look and feel whereas the golf course fits in Its location well, but is underutilized for a long-term delivery, It is our intention to bring continuity to these locations as it seems to be a main intersection that has more potential for public use, In looking through the city of Chanhassen we wanted to address the need for a product delivery of a luxury apartment living, combined with public access. We feel that what is being proposed does not currently exist In the greater Chanhassen area.With Highway 101 and Pioneer Trail being a very busy intersection,a high end single family use has no merit, moreover,there are plenty of different single family representations present, This concept will show that open space is important to the community and allows the open space to have a public use and opportunity for walking trails,tennis courts(possible a tennis club not shown on concepts),basketball courts,and batting cages.As one can see we have kept what we feel is the start of a wonderful community asset currently in the driving range on the west portion of this proposal. ■ Planning Commission October 17, 2017 2040 Comprehensive Plan Page 14 of'20 e -, . .prw, , q t - r, _ ^ry EY 7y/lip!r•::g• ' le- '..'',-0�s 6 - __.

The housing chapter addresses the city's goals for housing in the community. The following issues are discussed: • Inventory of existing housing including types and price. • Analysis of future housing demand. • Status of the city's progress toward the Livable Communities Act. • Discussion of the city's demographics.

The main goals encompass identifying and preserving natural resources, and increasing overall tree cover and maintaining the urban forest. Proper management of public natural resources is the overarching issue and critical to the success of Chanhassen retaining it's natural resources identity. This chapter of the plan addresses natural communities including forestry and water resources. The following issues are addressed: • Creation of a management plan for lands that have been acquired by the city. • Create an inventory of the natural resources. • The commitment of the city to preserve the city's natural resources; woodlands, wetlands, lakes, rivers and streams. • Consider adoption of GreenStep Cities initiative. PARK & RECREATION At the September 11, 2017 City Council meeting, the Parks and Recreation System Plan was presented. The Park and Recreation chapter deals with the following issues: • Current park system. • Additional parks that will need to be acquired in still developing areas. • Additional community ball field space that will need to be acquired to meet demands of future growth. • Our pedestrian trail and sidewalk system is widely recognized as one of the most comprehensive in the State. • In addition to local parks,residents are afforded convenient access to county, state and federal outdoor recreation destinations The Park and Recreation chapter of the 2040 Comprehensive Plan provides an overview and an analysis of the city's existing system. It identifies objectives and policies that will guide park and recreation decision making through the year 2040 as well as identifying key initiatives that will be completed to enhance the current park and trail systems. Planning Commission October 17, 2017 2040 Comprehensive Plan Page 17 of 20 In our community, we have numerous non-city recreational facilities that play an integral role in fulfilling residents' recreational needs. Minnewashta Regional Park, the Minnesota Landscape Arboretum, the Minnesota Valley Wildlife Refuge, Raguet Wildlife Management Area, golf courses and Camp Tanadoona are all important recreation destinations. Two regional trails owned by the Hennepin County Regional Railroad Authority and managed primarily by Three Rivers Park District can be found in both the southern and northern tiers of the city. In addition, regional trails are located along State Highway 101 and State Highway 5. TRANSPORTATION The transportation chapter is based on the city's 2040 Land Use. Updates to these plans recognize changes in land use, development patterns and other planning processes including: the Minnesota Department of Transportation's "Transportation System Plan 2008 - 2030" (TSP), Carver County's Transportation Plan 2017 Update, and the Metropolitan Council's Transportation System Framework. • The Plan shows how the city will achieve its goal of creating an integrated multi-modal transportation system which permits safe, efficient and effective movement of people and goods while supporting the city's development plans, and complementing the county,metropolitan, and state transportation systems that are within its boundaries. • Addresses existing and projected system deficiencies in the city's roadway network. • Establishes a functional roadway classification system for the roads within the community. • Discusses existing and future improvements and funding mechanisms for the construction of transportation improvements. • Includes a table allocating forecasted population,household, and employment growth by TAZ for 2020, 2030 and 2040. • Includes a map of existing and forecasted 2040 traffic volumes. • Identifies existing transit routes and services. • Incorporate transportation goals, objectives, and strategies outlined in the 2040 Transportation Policy Plan. SANITARY SEWER The sanitary sewer plan presents the existing sanitary infrastructure and the general location and size of future sanitary sewer infrastructure under fully-developed conditions. The Sanitary Sewer Comprehensive plan covers the future extensions of municipal service to future development areas. The plan deals with the following issues: • Organized and cost-effective plan to extend sewer service to development areas of the community. • Plan is based on anticipated land use,population growth and anticipated growth corridors. Planning Commission October 17, 2017 2040 Comprehensive Plan Page 18 of 20 • Maintenance and upkeep of the existing sanitary sewer infrastructure. • Reduction efforts for Inflow and Infiltration. • Capital Improvements Plan. The city has determined that all of Chanhassen will be included in our 2020 MUSA area. A list of strategic infrastructure improvements and sequencing has been developed necessary to install the infrastructure. There is a significant city investment required to extend urban services and there is a need to expand the service area that may connect to the system in a timely manner. Additionally, there are failing septic systems that should be replaced with a centralized sewer system. A lift station on the Powers Boulevard south of Highway 212 and forcemain from this lift station along the Highway 212 corridor are identified as the key infrastructure improvement for all the land south of Highway 212. WATER The Comprehensive Water Plan identifies the existing trunk and lateral watermain and wells within the city. The general alignment and size of future trunk watermain and the general location of future well sites and future water towers is also shown. The Water Comprehensive plan covers the existing and future extensions of municipal service to future development areas. The plan deals with the following issues: • Organized and cost-effective plan to extend water service to development areas of the community. • Plan is based on anticipated land use,population growth, anticipated growth corridors, and estimated future water demand projections for 2020, 2030, 2040. • Future needs for wells, storage and treatment facilities. • Maintenance and upkeep of the existing water infrastructure. • Capital Improvements Plan. • Identifies issues and actions to address water conservation and reuse,protection of source and sub-regional collaboration as part of the local comprehensive plan. SURFACE WATER The Local Water Management Plan(LWMP)was prepared in conformance with Minnesota Statutes 103B.235 and Minnesota Rules 8410. This plan is intended to provide the City of Chanhassen with information and direction in the administration and implementation of water resource management activities within the city during the period 2018-2027. It serves as a guide to projects,provides for effective allocation of resources, and sets forth a funding plan for projects and programs over the next 5 to 10 years. The City of Chanhassen realizes the importance of water resource management. In August of 2006 the city adopted the Second Generation Surface Water Management Plan. The LWMP is currently in the process of being amended and updated and is anticipated to be sent out for Planning Commission October 17, 2017 2040 Comprehensive Plan Page 19 of 20 review to appropriate jurisdiction by January 2018. The LWMP must follow a separate and mandatory review process pursuant to Minnesota Statutes 103B.235 and Minnesota Rules 8410. The city's Plan will adopt by reference the local 2018 - 2027 surface water management plan (LWMP) and will incorporate the 6 water resource goals as specified in the LWMP. Goal 1. Promote abstraction through infiltration, reuse and other methods where practicable to do so to provide flood protection, ground water recharge and improved water quality. Goal 2. Achieve water quality standards in lakes, streams, and wetlands consistent with their designated uses and established classifications. Goal 3. Protect and rehabilitate wetlands to maintain or improve their function and value. Goal 4. Prevent contamination of the aquifers and promote groundwater recharge to maintain base flows in streams and wetlands. Goal 5. Maintain primary responsibility for managing water resources at the local level where efficient to do so but continue coordination and cooperation with other agencies and organizations. Goal 6. Provide information and educational resources to improve knowledge and promote an active public role in management of water resources. CAPITAL IMPROVEMENTS /IMPLEMENTATION The Capital Improvement Program (CIP) Implementation Chapter provides a systematic assessment of the timing and magnitude of improvements that will be required to implement the comprehensive plan. Staff has included portions of the 2017-2021 CIP. However, detailed descriptions of the potential projects are not appropriate within the Comprehensive Plan since they are dealt with in the city's five-year CIP. The individual chapters describe the proposed improvements. The city annually prepares a five- year CIP,which goes into great detail about a specific project. That document has greater accuracy and more detail then is appropriate in a comprehensive plan. The chapter also list required amendments, code revisions and initiatives that the city will need to undertake to implement the Plan. Planning Commission October 17, 2017 2040 Comprehensive Plan Page 20 of 20 RECOMMENDATION Staff requests that the Planning Commission review the comprehensive plan, accept comments on the plan,provide comments and direction to finalize the 2040 Comprehensive Plan and concur with the submittal of the 2040 Comprehensive Plan for jurisdictional review.

During the update of your comprehensive plan, we would like you to consider how your plan can be used to protect your community's drinking water supply. Including drinking water information was also identified as part of your community's system statement required by the Metropolitan Council (https://metrocouncil.org/Communities/Planning/Local-Planning-Assistance/System- Statements.aspx). To support local planning, MDH worked with the Met Council to create an online tutorial 'Considering Source Water Protection in Your Plan' (https://metrocouncil.org/Handbook/Training/Tutorials.aspx) to assist you in evaluating how to include drinking water supply information and protection in your comprehensive plan. The City of Chanhassen Wellhead Protection (WHP) plan identifies the recharge area of the city(s) wells and the land uses and contaminants that may impact your drinking water supply. We encourage you to contact Kevin Crooks, your designated WHP Manager, to discuss important drinking water protection issues that can be included in the Comprehensive Plan update. In consultation with your City's WHP Manager, we would recommend you consider the following during your Comprehensive Plan Update: 1. Include the MDH Approved Map of the Drinking Water Supply Management Area that identifies the recharge area of the City's well(s). (see attachment) 2. Identify the vulnerability of your water supply to land uses as described in the City's WHP Plan. 3. Existing or future land use changes that may impact the City's water supply. 4. Evaluate and explore opportunities to reduce risk and minimize contaminant threats to the aquifer and city wells identified in your WHP plan through land use planning and local controls. An equal opportunity employer Ms. Kate Aanenson Page 2 October 5, 2017 Attached you will also find a fact sheet table titled "WHP Vulnerability and Land Use Planning Guide." The table is a useful guide that describes the main vulnerability designations found in WHP Plans related with contaminant issues, land use planning focus and examples of what you can do to help protect local drinking water supplies through local controls. Please contact me (Karen.s.voz@state.mn.us or 320/223-7322) or Lanya Ross, Metropolitan Council (651/602-1803 or Lanya.Ross@metc.state.mn.us) if you have any WHP or land use related questions. We look forward to working with you to help protect your community's drinking water supply and role land use planning can play in protecting this important resource!

The visioning exercise summary showed that people live in Chanhassen for many reasons. The small town feel but being within easy striking distance of big city amenities is important.The parks, lakes and trails with open space and recreation- al opportunities is important to people. Chanhassen has community values that are family friendly, promote health, en- gaging, and close knit neighbors. It is kid-friendly with strong schools, beautiful parks. It is a safe, neighborly place to live with low crime rates. The downtown is attractive and walkable. There are many housing choices and low taxes. Special attractions and community amenities are available such as the Chanhassen Dinner Theatres, Chanhassen Library, Paisley Park Museum,fishing and the 4th of July Celebration. Chanhassen has been nationally recognized many times as a great place to live.Our reputation is the result of years of dedicated service by many in the community, including our school districts, churches, businesses, civic partners, and public officials, all of whom have helped inspire and implement the values and vision that we enjoy today. It is our vision that Chanhassen is a community for life. By providing for today's needs and planning for tomorrow, we en- sure that Chanhassen's high quality of life is sustainable for future generations. Residents have a strong sense of commu- nity built through longstanding traditions, active civic and business organizations, and friendly neighborhoods. Residents benefit from a thriving downtown, an extensive park and trail system, excellent schools, countless community events, and the preservation and enhancement of our natural amenities. Chanhassen has so many things to offer: a wide range of housing stock to accommodate all budgets and stages of life, two high-performing school districts, a large commercial base so residents can live and work in the community, ample entertainment both in town and in neighboring communities, and easy mobility in and around Chanhassen by almost any mode of transportation. Residents appreciate these things and take pride in the community.The city recognizes the relationship between employment, housing, and retail demand. Many families have lived here since before Chanhassen was incorporated as a city in 1967.They've seen the city grow by 20,000 people in the last thirty years but still manage to keep its small town charm and appeal. Residents of Chanhassen are very engaged in their neighborhoods and also with the city. National Night Out, an annual community-building campaign that encourages residents to hold block parties and get to know their neighbors, continues to be a popular event.The city helps to coordinate efforts and schedules visits from city leaders and safety personnel, which helps the community feel connected to local government.The fire department is made up of almost all volunteers that give up their nights,weekends, and family time,to respond in emergencies.There are citizen commissions that each - work on a specific concern in the city: parks and recreation, planning, senior citizens, and the environment. Each corn- 0 mission has between seven and ten members that serve for one to three year terms, and act in an advisory role to the City gi Council.There is almost always a waiting list to get on any of the commissions.There are also countless opportunities to volunteer for each of the city's 12 annual community events, meals on wheels, coaching youth sports, and many more.All of these help to further the overall sense of community and keep residents in Chanhassen. 's U 3 1.21 Development The City of Chanhassen is defined by the Metropolitan Council as Emerging Suburban Edge which is expected to plan L for forecasted population growth at densities of at least 3-5 units per acre for new development and redevelopment. The = 2030 Comprehensive Plan anticipated a faster rate of growth than what occurred. This was due to the downturn in the housing market. The city estimates that by 2040 the city will be built out with a population of 37,100. The Comprehensive Plan is designed to serve as a guide for the local decision-making process. The cornerstone of the Comprehensive Plan process is the development and adoption of goals and policies which identify the desired qualities and overall vision for the future of the community. These goals and policies are based on the needs of the city along with unique characteristics and values of the community. The city recognizes the relationship between employment, housing, and retail demand and has strived to balance these factions to make a community for life. 1.3 I Economic Competiveness Since the adoption of the 2030 Comprehensive Plan in 2008, the city has: Added 400,000 square feet of office industrial space Added 300,000 square feet of commercial space. Added 1,085 dwelling units The city largest employers are: 2016 2007 �'� Percentage Percentage of Total City of Total City Employer Employees Rank Employment° Employees Rank Employment(') Lifetirne Fitness 1,218 1 21.0% 980 2 16.3% Instant Web Companies 1,193 2 20.6% 824 4 13.7% Rosemount Inc 943 3 16.3% 1,577 1 26.2% The Bernard Croup 581 4 10.0% - - Eastern Carver County Schools 400 5 6.9% 165 10 2.7% RR Donnelley 382 6 6.6% 280 7 4.7% General Mills 326 7 5.6% 475 5 7.9% Chanhassen Dinner Theatres 275 8 4.7% 300 6 5.0% Minnesota Landscape Arboretw 270 9 4.7% 240 9 4.0% Checkpoint Systems Inc 204 10 3.5% - - Super Value Headquarters - - 900 3 14.9% Byerly's - - 280 7 4.7% Total 5,792 6,021 m Z a 1 I Q Source: Survey by City Administration and Finance Departments c`+ t,�'I'he statistic for total City employment is not available,therefore the percentage represents the percentage of / the top ten listed. v '''''.i U 0 U 4 1.4 Attraction, Retention, and Expansion .- The city continues to work with existing business by participating in meet and greet activities to identify any issues that businesses may have.The city also works with the SouthWest Metro Chamber of Commerce hosting small business round tables to learn about local business needs. In September of 2016 the city participated in a Carver County initiated/Greater = MSP Broker event, an event marketing Carver County as a place to do business. The city and the Carver County CDA have worked together to add a new program to assist new and existing small busi- nesses in the county.The program,called "Open to Business", provides one on one business counseling to current and prospective entrepreneurs. Open to Business consultants work with entrepreneurs to develop a strong business plan, identify challenges and opportunities, and to tailor solutions to each business.The service is available free of charge to all county residents and any business located in Carver County. The city has secured grants to help businesses defray some of the costs of development. In the last 10 years working with MN Department of Employment and Economic Development(DEED)and Greater MSP, the city has attracted the following new business: » Federal Packaging relocated to Chanhassen to expand an existing business by building a new 140,800 square foot facility and adding 32 new jobs to the existing 15 jobs over a five year period. » The Bernard Group relocated to Chanhassen in order expand the size of an existing business. They were able to remodel a vacant building of 156,000 square feet and provide for 581 employees » Emerson Automation Solutions, with the new investments in the oil industry Emerson has invested $14 million in the converting 30,000 square feet of office space to factory space and added 80 new employees with the potential for more. --� 1.5 I Redevelopment With the maturing of the downtown core of the city, redevelopment is happening in the city. Buildings older than 30 years are being redeveloped into new business. The city has pursued DEED contamination grants as well as Metropolitan Coun- cil Livable Communities Demonstration Account(LCDA) grants to assist in redevelopment. The city is currently conducting an update to its Downtown Vision.The plan will examine current market conditions to stra- tegically direct redevelopment as the maturing businesses and infrastructure redevelop. 1.5 I Pending Projects Avienda With the update of the 2030 Comprehensive plan,the city dual guided 120 acres to either Office or Regional Commercial District. This site has access off Highway 212 and two county roads.The city has been working on the approvals for the project the last two years. The 2030 Comprehensive Plan states: DefinitionNision:A mixed commercial district with retail and entertainment uses of a scale and function that serves a regional market.The physical environment emphasizes an attractive, comfortable walking experience for shoppers and visitors and is designed to serve trail users and mass transit as well as automobile traffic. Centers of this type have at least 0 two major retail anchors and are characterized by the diversity and mix of retail and service uses within their boundaries. N Uses within this district should complement existing retail users in the other commercial districts. Development of these centers shall be planned as a group of organized uses and structures to accommodate a sensitive transition between --� commercial activities such as loading, parking of automobiles, lighting and trash collection and surrounding residential uses. Such centers shall be designed with one theme,with similar architectural style, similar exterior building materials, o and a coordinated landscaping theme.Vehicle and pedestrian access is coordinated and logically linked to provide a comprehensive circulation system. 5 c This project includes 5 districts. The goals this project is to be a walkable mixed used development. -0 » Sub-District 1 -Workplace—provides a location for uses with high concentrations of employees, such as medical/technology related office, and other corporate or institutional uses » Sub-District 2-The Village—provides the broadest variety, highest density and greatest intensity of development, encouraging both vertical and horizontal mixed use » Sub-District 3-Commercial—provides a location for larger scale retail and other auto-oriented commercial uses » Sub-District 4- Multi-Family—provides opportunities for high density senior or rental apartments » Sub-District 5-Low Density Residential—provides opportunities for small lot homes The total building square footage for this development will be 1,000,000 square feet of office, and retail with 613 dwelling units (including apartments, senior housing and town homes). The Lifestyle Center was given preliminary approval by the City Council in the spring of 2017. Construction is anticipated to begin in 2018. d U) C) d 0 0 U U 6 1.4 I Goals and Policies 1 .4.1 Land Use o Goals Create a mixture of development capable of providing a high quality of life and a reliable tax base. Policies » Create a land use plan that can be utilized as a fundamental tool for directing the community's growth and development. » Understand that not all uses generate revenue for the city, and strive for a mixture of development that will both meet the needs of residents and assure the city's financial health. » Encourage development within the MUSA, and support the planed and efficient expansion of the MUSA to increase the amount of developable land. » Support low density residential development in appropriate areas of the community in such a manner as maintain the aesthetic of existing single-family areas, and to create new neighborhoods of similar character and quality. » Designate sufficient land to provide for a wide spectrum of housing. Adequate land should be set-aside for medium and high-density land uses.The city will discourage the conversion of these areas to lower density uses in order to ensure that city's goals of providing a variety of housing options can be met. » Chanhassen will continue to direct commercial uses to the central business district. Development outside of the central business district shall complement, rather than compete with the existing commercial core. » The city will support the development of neighborhood and local service centers where appropriate.These uses maybe --� developed as part of a mixed-use or PUD; however, development of unplanned and strip commercial centers will be discouraged. » Industrial and office developments will be supported as a means of strengthening and diversifying the city's tax base. These developments should be planned in such a way as to minimize environmental, neighborhood, and traffic impacts. » Transitions should be created be created between different land uses.The more incompatible the land uses, the more important the transition zone.Whenever possible natural features should be used to create transitions between incompatible uses. When these natural features are absent, the Land Use Plan supports the creation of buffer yards with increased setbacks containing landscaping and berming to improve the separation of incompatible uses. » Development should be commensurate with ability of the city to provide services.Areas where services are available should be developed before services are extended to new areas. » Development should be seek to provide adequate internal street linkages.Growth should be directed so as to make efficient use of the existing road system. Developments should be planned to avoid running high traffic volumes through residential neighborhoods. » Areas outside the MUSA shall be preserved as agricultural zones or used to support very low-density development. This area should not be prematurely developed, and the city will discourage the creation and/or expansion of commercial and industrial facilities in this area. » Large lot subdivisions without city sewer or water shall not be required to utilize city services even when they are in the MUSA, until the majority of residents request to change their use. In these subdivisions the smallest permitted lot is 2 and a half acres. New lots meeting the 2 and a half-acre requirement may be created, assuming there is a suitable location for .--c septic and well. 0 U » A comprehensive and up-to-date set of ordinances shall be maintained to ensure high quality developments consistent with the comprehensive plan. Ordinances shall be reviewed and modified as necessary to improve the c quality of new development and ensure they incorporate high quality design, landscape, etc. » Chanhassen will work with other jurisdiction to combine resources. This included coordinating and collaborating with cities, counties, SouthWest Metro Transit, school districts, and the state on projects of mutual interest such as libraries, public works, collective waste management, arts,transit, recreation, etc. 3 I Housing Goals Goals Provide housing opportunities for all residents,consistent with the identified community » Balanced housing supply, with housing available for people of all income levels. » Accommodation of all racial and ethnic groups in the purchase,sale, rental and location of housing within the community. » A variety of housing types for all people in all stages of the life cycle. » A community of well-maintained housing and neighborhoods, including ownership and rental housing. » Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. » The availability of a full range of services and facilities for its residents,and the improvement of access to a linkage between housing and employment. Policies » Continue to enforce the City Code regarding property maintenance to maintain the existing housing stock. • As state and federal funding permits, efforts should be made to provide low and moderate housing where needed, to provide balance to the generally high cost of new housing. » The city should promote the use of state and federal programs to reduce land costs for developers of low and moderate-income housing. » The city will cooperate with other governmental units and public agencies to streamline, simplify, and coordinate the reviews required for residential development to avoid inflating the cost of housing due to unnecessary delays in the review process. » The city will continue to encourage the development of affordable housing;the city may increase the permitted net density of a project by 25 percent.The "bonus" units must meet affordable housing criteria as defined by the city. Developers shall be required to enter into an agreement ensuring the affordability of the units. » Subsidized housing should be given equal site and planning considerations to non-subsidized housing units and should not be placed in inferior locations or in areas that do not provide necessary urban services including transit and commercial services. » The city will continue to provide alternative types of homes including smaller lot homes,townhouses,etc.that will supplement the conventional single-family homes. » New residential development shall be discouraged from encroaching into natural resources or physical features. EHousing development methods such as PUDs,cluster development, and innovative site plans and building types, should be encouraged to help conserve energy and resources for housing. » Citizen participation in developing plans and implementing housing programs is encouraged in redevelopment, rehabilitation,and in planning for the future. » While density is given by a range in the comprehensive plan,the city shall encourage development at the upper end of the density range. 8 • The city will promote the mixing of housing densities within projects in order to provide a wide range of housing styles a and types. Such mixed densities must provide appropriate transitions for existing development. The city will continue to participate in the Livable Communities Act of 1995 as stated in the Housing Plan. The city will promote the integration of life-cycle housing opportunities throughout the community.Affordable and subsidized housing shall not be overly concentrated in one area of the city. 4 I Natural Resources Goals Goals 1.

Policies General • Thoroughfares and major routes should be planned so as to reduce conflicts between external traffic and local traffic while facilitating development in the community. • Through the development review process,the city will strive to discourage development from occurring within the designated roadway corridors as well as limiting access to collector streets, minor arterials, intermediate arterials and principal arterials. Access points to the regional roadway system should be adequately controlled in terms of driveway openings and side street intersections. Promote safe and convenient access connections between the highway system and major commercial areas, industrial uses, and residential neighborhoods. Roadways » Encourage multiple uses of right-of-way areas accommodating various modes of transportation. » New roadway facilities should be constructed in conjunction with new developments and designed according to the intended function. They should be planned and designed to be compatible with the surrounding environment. Existing roadways should be upgraded when warranted by demonstrated volume, safety or functional needs. Roadways shall also be maintained and repaired to ensure the greatest possible useful life. Residential street systems should be designed to discourage through traffic and to be compatible with other transportation modes including transit, bicycle and walking. The city will implement roadway design standards and inspection practices which ensure proper construction. Streets shall be designed and operated to enable safe access for all users, including pedestrians, bicyclists, motorists and transit riders of all ages and abilities. Transit » The city encourages all forms of ridesharing in order to reduce vehicle miles of travel, reduce petroleum consumption, and improve air quality. N The city will review all major new developments in light of the potential for ridesharing including bus accessibility, preferential parking for carpools/vanpools, and mixed use development. • The city will consider support for Federal, State, Metropolitan and local efforts directed toward the access of rail transit for the community, the region, and the state. The city encourages cooperation with the Metropolitan Council and Southwest Transit Commission in order to provide future transit service to and within the community. The city will support the development of park and ride facilities that 0 encourage transit use. E Parking The city will continue to review new developments for adequacy of parking based upon need and the potential for joint use of parking facilities. Sufficient parking,transfer and bus stop facilities should be provided to meet the needs of mass transit in major employment and commercial areas and in higher density residential and mixed use areas. Pedestrian/Bicycle 14 » Major activity centers should provide accessibility to pedestrians and bicycles including necessary bicycle parking facilities. » The city will promote increased development of bikeways and trail facilities in order to conserve energy resources, enhance recreational opportunities, improve health and assist in the abatement of pollution and congestion. » Pedestrian and bicycle trails should be interconnected with major generators and have continuity across major roadways and other barriers. » Sidewalks and/or trails should be required in commercial, industrial, and residential areas;adjacent to schools and other public buildings and along at least one side of collectors and other high volume roads. Other Mapped Road System.The city will utilize the land use plan and transportation plan maps to illustrate planned road alignments and to facilitate their acquisition and construction as new developments are proposed. The plan maps will illustrate all collec- tor and arterial street alignments. They will also be revised from time to time by the city during the subdivision review process. Subdivisions.As a part of platting,each development should provide dedication and improvement of public streets consistent with the standards found in city ordinances.The city will promote the provision of street and pedestrian connections to maximize safety and ease of access. Buffer. Sufficient setbacks and/or berming should be designed into all development projects adjacent to major public roadways. Capacity. Coordinate existing and planned transportation facilities and their capacities with land use types and densities with particular emphasis on land development in the vicinity of interchanges and intersections. Maintenance.The city will continue an ongoing maintenance program to maximize the community's investment in transportation facilities. Circulation. For proposed developments,the city will require detailed circulation and access plans which depict the impact of the proposed development on both the existing and future transportation systems. Arterial Deficiencies.The city will support Federal, State, Metropolitan and local efforts directed toward the timely construction of a new Minnesota River crossing connecting Trunk Highways 169 and 212, upgrading of TH 5 west of TH 41,realignment and construction of TH 101 south of Pioneer Trail, upgrading of TH 101 north of TH 5,TH 41, and other facilities serving the area. Chanhassen will coordinate efforts with Eden Prairie,Victoria and other appropriate jurisdictions to insure that TH 5 and 101 continue to function effectively. Construction and Maintenance.Chanhassen will coordinate construction and maintenance of hard surfaced local streets,collectors, and arterials. Interconnect Neighborhoods. It is the city's policy to require interconnections between neighborhoods through the construction of local streets to foster a sense of community,to improve safety, encourage health and to provide a convenient access for residents. 7 Sewer Goals and Policies The timing of future trunk sanitary sewer improvements will be influenced by several parameters including development pressures in specific areas,failing on-site septic systems, regulatory requirements,availability of funds,etc.As a result it is difficult to accurately predict the time of future improvements especially those which may occur far into the future.Therefore, 5 the Capital Improvement Program is intended to serve as a guide only for future fiscal planning and should be reviewed on a --� regular basis as more current planning and cost data becomes available. The following items are general policy guidelines to be considered when reviewing and/or revising the city's fee structure: "' U 15 System Expansion(Orderly Development) \..6 Development shall occur in an orderly fashion. Properties that abut parcels served by municipal utilities will be considered as the next feasible property for development.The city may limit development activities to selected areas. Petitions to expand in ' areas not already under development will be considered. Factors that will be considered include, but are not limited to;capac- ity in the MCES interceptor,capacity in the city's collection system, economic factors including costs, number of developments under construction and the staff resources available to review the requested development. Leapfrogging Leapfrogging refers to the circumstance where certain parties want to develop an area not currently adjacent to the limits of the City of Chanhassen's existing sewer system.The applicant wants to "leapfrog" over areas located adjacent to the city's existing services that would be the next logical area to be developed. In this circumstance, the City of Chanhassen could decide whether or not to approve such development. If approved, it is recommended that the interested property owner pay for the entire cost of installing services to their property and resulting system upgrades. The developer shall be offered no credit or reimbursement for these costs. If development of the property that was "leapfrogged" is later initiat- ed, payment of all trunk charges for the property will still be required regardless of the fact that the facilities were already installed before development occurred. Overdepth and Oversizing The costs of additional depth shall be defined by differences in cost for the depth required by the development and the depth required for trunk facilities. Trunk oversizing as defined by the city and installed by the developer will be credited using the differential of pipe costs between the larger and the minimum pipe size required for the development. Bid pric- ing shall not be the sole determinate in defining a developer credit. The city shall determine if a credit will be given for a project. Lift Stations Trunk lift stations should be defined as those servicing more than one single development project.The trunk fees will pay for 100 percent of the cost of trunk lift stations. Lift stations that do not fit the definition for a trunk lift station are to be paid for by the developer. All lift stations shall be designed and constructed in accordance with city standards. The city will consider cost sharing for other lift stations if it is found that a particular lift station may be able to serve a greater area than the single development. The cost sharing shall include the oversizing or overdepth required to serve additional area and associated SCADA system costs to establish the lift station on the city's SCAD A system. Existing Developed Unserviced Properties There are a number of existing developed areas that do not receive sewer and water service within the city limits. The trunk system has been designed to handle all existing developed unserviced properties within the city, but it is not the policy of the city to initiate a sewer extension project. If an individual property owner or group of neighboring property owners would like city sanitary sewer services where it is not yet available,the city will review whether or not it is econom- ically viable. Existing developed, unserviced residential properties will be assessed or required to pay connection fees as required by the City Code. Existing Non-Residential Unserviced Properties IExisting unserviced commercial/industrial or other non-residential properties wishing to expand or hookup to municipal g utilities shall be treated the same as new development and will be assessed or required to pay connection fees as re- quired by the city. Recommendations Based on the results and analysis of this study, it is recommended that the City of Chanhassen and the City Council, where applicable: » Adopt this report as the Comprehensive Sanitary Sewer Plan for the City of Chanhassen. U 16 » Review and update the CIP for trunk sanitary sewer facilities every year to reflect sewer improvement projects necessary for the next five year period. » Proceed with future sanitary sewer improvements in accordance with the initial 5-year capital improvement program. Y » Continue to reduce Ill to the existing collection system and maintain provisions for preventing Ill from entering = the sanitary sewer system with new construction. 8 Water Conclusions and Recommendations Supply Improvements Firm supply capacity(the supply capacity with the largest pump out of service) should be greater than maximum day demands. The city is currently in the midst of constructing West Water Treatment Plant,which is estimated to have a ca- pacity equal to the recently constructed East Water Treatment Plant(6,000 gpm). In order to fully utilize these two plants, it is estimated that four new wells will be necessary during the life of this plan to meet projected water demands based on projected development in the city. Distribution System Improvements Trunk main looping should be a priority in the expansion of the service area and in water main replacement projects. The proposed layout of trunk water mains in this report would provide water supply and fire protection capabilities to existing and projected service areas. In addition, recommended trunk mains will connect water supply and storage facilities with points of use on the system. The city can also work towards the eventual combination of the Lake Riley and Interbluff pressure zones, which may be the most ideal location for a new elevated storage tank. Storage Improvements The volume of water storage needed in Chanhassen is dictated by daily demands as well as fire protection. Currently, storage capacity is meeting system needs. Projected demands will create a need for one additional 1.0 MG elevated water storage tank over the life of this plan. A new concept, which places a new tank in the combined Lake Riley/lnterbluff lower pressure zone which will help supply these pressure zones with water as well as stabilize system pressures. Report and Model Update This report should be reviewed on an annual basis. Changes in development type or densities can have significant impacts on a water system's performance, especially during drought conditions or emergencies such as fires. A report update should be planned for approximately 5 to 10 years dependent on development pressure. The water system model produced as part of this project is a valuable tool in assisting with design and construction of Chanhassen water system components. It can be easily updated on an annual basis and used to evaluate the impacts of proposed developments or project phasing. A copy of the computer model will be provided to the city. 9 I Surface Water Goals 0 » Promote abstraction through infiltration, reuse and other methods where practicable to do so to provide flood protection, ground water recharge and improved water quality. » Achieve water quality standards in lakes, streams, and wetlands consistent with their designated uses and established classifications. » Protect and rehabilitate wetlands to maintain or improve their function and value. 0 » Prevent contamination of the aquifers and promote groundwater recharge to maintain base flows in streams and wetlands. 17 c Maintain primary responsibility for managing water resources at the local level where efficient to do so but continue coordination and cooperation with other agencies and organizations. Provide information and educational resources to improve knowledge and promote an active public role in management of water resources. c m L Q E 0 C) I .1, c as x, Chapter2 y q Land Use 4' H ASS z * -rf-,,,,.1' f_vi - .t -' `,t ". a. .�'• Arta f.. ram• 4 1 ramd') • ..-:"..- 1 -.--4,-- :.,_,,,,...„‘• .. , ,s.,, -. ,,,,,.. • *— „I_ igill- . , —)."1114„,..-..,.

LandUse a) J 2.1 Introduction The purpose of the land use plan is to ensure the community's quality of life by identifying appropriate locations for all types of uses and provide for the orderly expansion of municipal services through the Metropolitan Urban Service Area(MUSA) phasing plan.The land use plan creates the framework that guides zoning and subsequent land use decisions.This plan establishes the guidelines that the City Council, Planning Commission, and Parks and Recreation Commission use to make decisions on individual development requests, especially those that involve zoning and land use amendments. 2.2 Developmental Influences Lakes,wetlands, and woods define Chanhassen. Natural resources such as the sensitive water resources contained within Assumption Creek, Seminary Fen, and the wetlands associated with the Minnesota River are especially important. The city's 350 wetlands occupy over 2,370 acres, nearly 15%of the city's total area. Additionally, the city has 12 mapped lakes covering 1,526 acres, and storm water ponds account for another 78 acres of aquatic habitat. The city is also home to the headwaters several major streams including Bluff Creek, Riley Creek, and Purgatory Creek. Cumulatively, surface water features account for 4,269 acres of the city's surface area. Many of the city's parcels either take advantage of or are impacted by these water resources. The city is bordered by the Minnesota Landscape Arboretum to the west and the Minnesota River to the south.The com- munity's northern boundary is predominately low-density residential housing. Surrounding Chanhassen are the communi- ties of Shorewood, Minnetonka, Victoria, Shakopee, Chaska, and Eden Prairie.To the East, Minnetonka, Eden Prairie, and Shorewood are almost entirely developed, and Chanhassen expects to see continued growth in all land use sectors. One of the biggest factors influencing growth in the southern section of the city is the anticipated upgrades and realign- ment of Highways 101/61. In 2014,the City of Chanhassen commissioned a study to investigate the feasibility of exiting city utilities to the County Road 61 corridor.This area encompasses 1,430 acres and includes numerous protected areas including the Bluff Creek Primary Zone,the Seminary Fen Scientific and Natural Area, and the MN Valley National Wildlife Refuge. Once these areas are removed from consideration only 12%of this region is developable. Despite these constraints,the study determined that extending utilities to the area was feasible, and the city has guided these properties for the uses and densities necessary to ensure that they achieve the highest and best use possible while being responsive to the area's unique natural setting.The city's goal is to create an attractive southern gateway along this corridor. Development within this area will be contingent upon the extension of city services into this area,which is itself contingent upon the realignment of Highway 101. Upon completion of the study the land use amendments were approved by the Metropolitan Council in February of 2015.

It is the city's policy not to create additional lots that do not have access to municipal services. 2.5.1 [ Residential - Large Lot Properties in this district are predominately large-lot estates or, more rarely, agriculturally oriented dwellings.These large- lot residential areas are generally clustered south of Pioneer Trail; however, other concentrations exist north of Trunk High- way 5, east of Galpin Boulevard along Lake Lucy Road, and South of Trunk Highway 5, east of Galpin Boulevard along Timberwood Drive. Large-lot residential developments are intended to have a rural character and are subject to 2.5-acre minimum lot size. The city saw a proliferation of large-lot residential subdivisions in 1987 as developers rushed to subdivide before the current one unit per ten-acre density limit went into effect. Given the one unit per-ten acre density limit, there are very few properties that could subdivide to create new large lot residential properties. It is unlikely that there will be a significant expansion of this land use category. For projecting land demand and average of 0.4 net units per acre was used. Large- lot residential is zoned as either A-2(Agricultural Estate District)or RR (Rural Residential District).

For projecting land demand, an average density of two dwelling units per acre was used. Low-density residential areas can be either zoned RSF(Residential Single Family), R-4(Mixed Low Density), RLM (Residential Low and Medium Density), or PUD-R(Planned Unit Development Residential). .a c d E 0 Ug U 25 FIGURE 2-4 12016 GENERALIZED LAND USE, CITY OF CHANHASSEN, CARVER, & HENNEPIN COUNTIES ' t_ y `Excelsior Minnetrista _ I Shorewo =- i Minnetonka RI - Victoria - ' F .

For projecting land demand, an average density of six units per acre was used.The following zoning districts can fall within the medium-density residential area: R-4(Mixed Low Density), RLM(Residential Low and Medium Density), R-8(Mixed Medium Density), or PUD-R(Planned Unit Development Residential). Medium density areas are used to create transitional zones between low-density residential and commercial, office, or high-density residential areas. 2.5.4 Residential - High Density The city's highest density category provides for developments with a density range of 8 to 16 units per acre, and it is typically used for apartments and condominiums. For projecting land demand and average density of 10 units per acre was used. Areas guided high density residential can be zoned R-8(Mixed Medium Density), R-12 and R-16(High Densi- ty Residential), and PUD-R (Planned Unit Development-Residential). High-density residential areas are located on major transportation corridors,typically near transit, commercial centers, and employment centers. 2.6 I Industrial Land Use Most of the city's existing office/industrial parks are fully built out. The city has guided areas near the intersection of Arbo- retum Boulevard and Audubon Road and the intersection of Galpin Boulevard and Lyman Boulevard for future develop- ment as office/industrial parks in order to meet anticipated demand. The city also uses PUD zoning to create dedicated industrial parks. Since 2008 the city has added over 400,000 square feet of industrial uses. Industrial uses are facilitated by the IOP(Industrial Office Park)and PUD (Planned Unit Development-Office/Industrial)zoning districts. 2.7 I Commercial Land Use Traditionally the city has focused on directing commercial development into the Central Business District.This policy has helped Chanhassen created and maintain a strong business community. However, between the city's growth and the re- alignment of Highway 212, the city has determined that there is a potential for significant commercial development outside of the downtown core. In order to take advantage of this opportunity the city guided land for Regional Commercial use, and is in the process of moving the Avienda regional lifestyle and mixed-use center through the approval process. This development will significantly increase the amount of commercial real estate in the city, and will create a second, compli- mentary, hub of commercial activity. Since 2008 the city has added over 300,000 square feet of commercial uses. 2.7.1 ( Central Business District DefinitionNision: A compact walkable district featuring a wide variety of business, commercial, office, and residential uses providing a comprehensive range of services at higher development densities than are present elsewhere in the city. The Central Business District is a dense concentration of jobs, services, housing, and civic uses.The city's highest densi- ty developments are located in the Central Business District.The scale of these developments is supported by infrastruc- ture such as the Chanhassen Transit Station. The proximity of numerous commercial and civic uses accessible by attrac- tive walking paths draws shoppers, visitors, and residents to the area and promoting multiple trips between destinations. o§ New developments in this district are encouraged to complement the existing mix and to contribute to maintain a vibrant g and active district over the course of an extended day. Attention is also given to creating attractive and comfortable pe- destrian links between varied uses within the district. 21 Goods and Services Examples p Residential (High Density) Office 0 Entertainment(Restaurants, Theaters, Music Venues) 28 » Retail, Grocery, Household Goods and Services cv » Fitness Activities » Hotels J » Health Services(Clinics) Zoning districts within this land use is CBD(Central Business District)or BH (Business Highway). Previously,the BG (General Business District)zoning district was used within the area;however,these areas were rezoned as CBD.The BG zoning classification is still the underlying zoning district for several PUDs within the Central Business District. 2.7.2 I Neighborhood/Convenience Commercial DefinitionNision: Neighborhood/Convenience commercial districts are intended to host business that provide the daily goods and services needed by residents or nearby employees. These districts are oriented towards smaller sites with direct access to collec- tor streets and are preferably located close to intersections of collector or arterial roads.These land uses are scaled to be compatible the surrounding districts,which are typically residential. Neighborhood/convenience commercial uses should have a minimal impact on surround properties, as measured in terms of hours of operation, signage, and noise, light, and odors generated. No single use in this district should exceed 10,000 square feet in gross built area. Goods and Services Examples » Small to medium sized restaurants(no drive through windows) » Dry Cleaning » Neighborhood Scale Health/Fitness Services » Office » Day Care » Neighborhood Scale Convenience Store » Gas Stations » Personal Services The zoning application for this land use is BN (Neighborhood Business District). 2.7.3 I Community and General Commercial DefinitionNision: Large-scale commercial and office districts requiring high visibility along arterial roads. This type of development has the capacity to generate enough lighting, noise, and traffic to have a moderate impact on the surrounding areas. These developments are located in areas with access to arterial streets, preferably at intersection with collector and arterial streets, have moderate to large-sized sites, are within the MUSA, and have environmental features, such as soils and topography, suitable for compact development.The projects must have adequate buffering by physical features or adjacent compatible uses to protect nearby residential developments.

U 29 `R 2.7.4 ' Regional/Lifestyle Center Commerical DefinitionNision: ea -, A regional destination featuring a highly walkable commercial core complimented by residential and office uses. A region center is a mixed commercial district with retail and entertainment uses of an appropriate scale to serve a region- al market.The development should be designed to serve pedestrian and mass transit users along with automobile users. Its design should create an attractive and comfortable walking experience for visitors and residents. The center's retail component should be integrated with its office and residential components,with mindful transitions between land uses. Goods and Services Examples: » Entertainment » Department Store » Comparison Shopping » Specialty Retail/Boutique » Restaurants » Hotels » Residential The city has guided 160 acres at the southeast corner of Powers and Lyman Boulevards as a potential regional/lifestyle center.The city has recently approved PUD(Planned Unit Development)zoning for this area in to accommodate the Avi- enda project.The zoning for this land use is PUD-Regional Commercial. 2.7.5 I Business Fringe District This district was created to facilitate limited commercial activity in areas outside the MUSA. Currently the district is locat- `-- ed at the intersection of Highway 101 and Flying Cloud Drive; however,the area is ultimately envisioned as a mixed-used development,with the existing uses to be phased out once urban services are available.Zoning in this area is BF-Fringe Business District. 2.8 ; Public Semi-Public Land Use There areas are intended to serve a communal or public purpose. Uses with this designation include the Minnesota Land- scape Arboretum, Campfire Girls(Camp Tanadoona), public school buildings including Districts 112 and 276, city owned property, and the Eckankar campus. Zoning is either 01 (Office and Institutional District,A2(Agricultural District), or RR (Rural Residential District). 2.9 I Agricultural Land Use Consistent with the Thrive MSP 2040 regional development framework, no zoning district provides for purely agricultural land use. Some of the city's larger properties are used for crop production, but as the city continues to urbanize these types of uses will become increasingly atypical.The city has reduced the development pressures on agricultural land though it's MUSA phasing plan. It is the city's policy to protect its rural regions for development until municipal services • are available and requested. Some areas in the city are guided agricultural, but they are unlikely to be developed due to .2 being located within flood plains or having extensive wetlands, including the Minnesota Valley National Wildlife Refuge and Raguet Wildlife Management Area. us 2.10 I Office Land Use d The city is experiencing increased interest in office uses, and projects that over 200 acres of land will be developed for • office use by 2040. In order to accommodate this demand the area near the intersection of Highway 212 and Pioneer Trail �.L is guided for office use. Additionally, the recently approved Avienda lifestyle center is expected to include 150,000 square ° feet of office space. Land intended for office use is zoned 01 (Office Institutional District)or PUD(Planned Unit Develop- ment-Office/Institutional)zoning districts. U 30 2.11 I Mixed Use land Use -� The mixed-use land use allows for the blending of commercial and high-density residential developments. Both Village on the Ponds, located south of TH 5 and east of TH 101, and the Southwest Villages, located at the intersection of Lyman Boulevard and TH 101, are examples of more urban feeling mixed-use developments. Additional land near the inter- section of TH 101 and Flying Cloud Drive isguided for mixed-use. These types of developments are facilitated by PUD (Planned Unit Development)zoning. 2.12 Parks and Open Space Land Use The amount of land guided for Parks and Open Spaces includes almost 140 acres of potential new park and open space. The Bluff Creek Overlay District is an important mechanism for preserving open space, and the city continues to use the district to encourage the use of density transfers to preserve woodlands and bluffs adjacent to these areas. City parks and the Lake Minnewashta Regional Park fall into this land use designation. All zoning districts permit the creation of parks. 2.13 I Policy Issues 2.13.1 I Buffer Yard Concept To the greatest extent possible, natural features should be used to create buffers between residential and non-residential uses.When these features are not present, the City Code requires the creation of additional setback or other forms of buffering, including landscaping. 2.13.2 I MUSA Impact on Existing Lots The city still has homes serviced by on-site sewage disposal systems. While these systems are an environmentally ac- ceptable method of dealing with waste generated by large-lot subdivisions, they become more problematic when utilized to service smaller parcels. For this reasons, it is the city's policy that these subdivisions remain large lot with a minimum lot size of 21 acres. Requests for changes may be made incrementally(on a case-by-case basis), but it is city policy to review land use and zoning changes on an area wide basis. 2.13.3 I Comprehensive Plan Zoning Map Inconsistency Properties not served by urban services shall not be rezoned to a category consistent with their land use designation until urban services are available. Current zoning of a parcel at a less-intensive land use designation may remain until that time. Land use may only be intensified once the property has access to urban services. 2.13.4 I Maximum Use of Allowable Density Due to the city's housing goals and participation in the Livable Communities Act,the city has the right to deny any project that does not meet the minimum density required by its land use designation.Valid reasons for denial include deviation form city requirements or offsetting the goals of the city. The city may provide developments with a density bonus to facili- tate the provision of affordable housing. 2.13.5 I MUSA Staging d The Metropolitan Urban Services Area(MUSA) is defined as areas within the city that may be served with centralized infrastructure service and which may therefore develop at urban densities and intensities. The purpose of this boundary is to define the areas withinthe Twin Cities Metropolitan Area that are eligible for"urban services", specifically sewers, municipal water systems and particular types of transportation systems.This boundary line is defined and maintained by cv the Metropolitan Council to assist in the orderly development of the metropolitan area. The city has identified the key infrastructure, lift stations, wells and streets needed to expand into the 2020 MUSA area. It is the city desire to direct development to those properties that have municipal services. Assuming that current development patterns continue the majority of the city will be developed by 2040.The pace of ex- g pansion of the MUSA will depend on availability of sufficient developable land to support the required infrastructure. 31 Cl" 2020 MUSA Map -,) fti-e _ _ ..,,az,-vlie- .... ....-..akt•-,,im.17.a tvl,tm:-Tivolip,:lailt,:illirAPPUIrieff-aWAVIeliatia CC F.- ii"V•41'.04Ate'i AS=1;1?;•:01, ,........ _.• .,,,, ;,.......,,k-,m6j.., 4..e-.m 414111r.. ,2.a•-‘1...V.m.,-16,niki40,0:::in_t.:.x. ,P41!.07:40ifitillibliiiiiIIIIIII .,i• ; Ors'Aiare 1%217.irlgll.sirtflirliml'Lfl •l1/'.:'.irs'ljililtll'ZfrPri41:7Sit:.jICEr:;;: 4Y4f4.7!14=1411V4 :rfls''jil s.a.."4-,-.6*-•!4-; il:01 1.41::72•11. :- ; , All; VVI: — 41•V;,!:0:.=47-f52E,41","',:;;;;:lif II 114.1.1i ly row Ri'.1.."',.....T.M.0....5 .- ‘ ..1.....111,1. 4.Y.,S,r.`• fi',.:S AVMs;IIIIV'sw, . ie:01111:2 ES r..-1 mei 72:,.. --,.:-1, :::,1.7,..1.':i ' L1/4. ,1-2 :4311, Iix,...IFA) - as w*fi4!;;-:,.-v,,,\., ....7„..,............,....Wr • .•."1-. t.... :.--4,.:::: szvr:',-,,..

While this plan does not contemplate a land use change it will examine the existing market conditions and may make recommendation for uses and infrastructure improvements. 2.14 j Historic Preservation 2.14.1 Introduction The city introduced a historic preservation section in the 2030 Comprehensive Plan.With the rural portion of the city ripe for development and the desire to preserve the city's history, it is the appropriate time to formalize the city's goals for his- toric preservation. 2.14.2 Background "The history of Chanhassen begins in many places. It begins in Germany where social unrest moved some to travel across an ocean to find a new home. It begins in western Massachusetts in small towns in the Connecticut River Valley. It begins in the halls of Congress as the United States government decided how to distribute land.The area that we know as Chanhassen had its own history as well. Native American populations lived there for thousands of years. Research proj- ects show evidence of habitation around Lake Susan, Minnewashta, and Lotus Lake as early as 6000 BC. For one hun- dred years, the Dakota were the primary native group, moving into the land and displacing the Iowa people sometime in the 1750's.They had no major villages in Carver County. In 1851 the treaties of Transvers de Sioux and Mendota provided a cash payment to Native Americans in return for the land. Within weeks, settlers began staking claims." -� Source: Chanhassen: A Centennial History. The Preemption Act of 1841, a statute passed by the U.S. Congress, permitted settlers to stake a claim of 160 acres and, after about 14 months of residency,to purchase it from the government for as little as$1.25 an acre before it was offered for public sale. Congress repealed the Preemption Act in 1891. The first wave of German immigration to America came when Minnesota lands opened for sale.A German Colony gathered around a lake. Since all the families came from Bavaria, many began to refer to the lake by that name.The Northampton Colony migrated from several towns in the Connecticut River Valley and settled around Lake Minnewashta. In 1887,the Franciscan Brothers relinquished title to the property around St Hubert's Church and the town of Saint Huber- tus was platted. When the Village of Chanhassen was organized in 1896, St. Hubertus opted for the traditional name of Chanhassen. On April 21, 1896, Chanhassen was incorporated as a village government. "When the population of a township exceeds 2,000, the Minnesota Municipal Commission(MMC) is required to hold a hearing to determine its legal future. Chanhassen Township was the largest piece of unincorporated land in Carver County and became a target for the competing interests of local governments. Chaska made the first move, petitioning to annex 3800 acres of Chanhassen Township, including the new Hazeltine Golf Course and the proposed "New Town of Jonathan" z annexation. In one legal maneuver, Chanhassen lost its southwest corner. The township board was outraged and fought the ruling all the way to the Minnesota Supreme Court where they lost.Victoria began consideration to annex the north- west corner. The township permanently lost sections to Chaska and Victoria. The MMC issued an order in December 1966 that the township and village would merge if there were no objections within the community." On May 2, 1967,the merger was approved by a vote of two to one. Chanhassen Township was disCD - CD solved." Source Chanhassen.A Centennial History. V 33 °' 2.14.3 I Historic Preservation cHistoric Preservation is the act of maintaining and repairing existing historic materials and the retention of a property's form as it has evolved over time. When considering the United States Department of Interior's interpretation, "Preservation calls for the existing form, materials,features, and detailing of a property to be retained and preserved. This may include preliminary measures to protect and stabilize it prior to undertaking other work—or protection and stabilization may be an end in itself, for example, in an archaeological project." Historic Preservation is a vital tool in the effort to save historic buildings and locales. It helps maintain a community's historical roots and provides various educational opportunities. d CI.

Property owners opposed restrictions on their properties that would impose limitations on exterior improvements and remodeling. They welcomed guidelines but not ordinances. The state and county play a role in historic preservation.The state is in charge of making recommendations of proper- ties that are worthy of nominations as historic properties or sites. The recommendation is forwarded to the Keeper of the National Registrar of Historical Places. The Carver County Historical Society's role and mission is to collect and preserve artifacts and objects. Carver County was awarded a grant and hired The 106 Group, Ltd. to identify historically significant sites. This process included sites listed on the National Register of Historic Places, sites eligible for National Register of Historic Places, and a photo of the property. The 106 Group, Ltd. phased their study into stages: Stage 1:Baseline Data Obtain data on the known historic, archaeological and cultural resources Stage 2:Develop Priorities Delve further into the identification of additional, previously unidentified historic resources Stage 3:Survey and Policy Development Identify and evaluate historic resources that are significant to the heritage and formulate policies with regard to the protection and preservation of those resources. Based on the available information, the city will establish a Recognition Program of historic properties and buildings,with owner's consent, designed to encourage private property owners to use, maintain, and protect their historic properties. The City of Chanhassen will rely on Carver County to be the Historic Preservation Organization. Properties requesting a historic designation or funding will be directed to Carver County Historic Society. 2.14.4 I Historic Buildings and Structures The city contains a number of structures that embody its architectural and cultural heritage. The city will continue to encourage the preservation, interpretation and active reuse of privately-owned historic buildings and structures, and will work to protect such buildings and structures to the extent feasible during the development process.The city will also continue to preserve and restore the historic structures it owns. The city will not actively pursue the acquisition of historic sites or structures. 2.14.5ILand Whenever possible, landmarks should be preserved on the site where they are located. Failing that, they may be moved, if feasible. A demolished landmark may be commemorated in one or more of the following ways: Naming the new structure in honor of the old. Inclusion of some architectural features of the original structure in the new structure. CD » A display area in the new structure which may include photographs or other memorabilia of the old structure or site. oA plaque or marker of appropriate size describing the original structure and its significance.

Since Chanhassen became a city in 1967,the number of housing options has become more diverse, Housing choices have expanded from single-family detached homes to include apart- ments, condominiums, attached-single family, senior living facilities, and group homes. "Chanhassen is a Community for Life" and thus has provided land use and zoning supporting a variety of housing options for residents in all stages of life. The housing plan will examine existing conditions and provide an analysis of housing needs.The data comes from the June 2014 Maxfield Research Inc. "Comprehensive Needs Assessment for Carver County",the US Census,the Metropoli- tan Council, the May 2017 Community Partners Research, Inc. "Carver County Affordable Housing Update",the Minneap- olis Area Association of Realtors, and the City of Chanhassen. Whenever possible the City has attempted to use the most recent information available; however, some older sources, particularly the 2014 Maxfield study, provide unique date not found elsewhere. 3.1 I Overview of Existing Housing FIGURE 3-1 I HISTORIC COUNT OF HOUSING TYPES Housing Type Type of housing and its in structure 1990 2000 2010 2015 w Owner Renter Owner Renter Owner Renter Owner Renter Single family detached 3,102 105 5,312 88 5,992 115 6,111 144 Single family attached 292 331 920 37 928 169 1,265 316 Duplexes 8 21 10 23 13 0 4 17 Buildings 3-4 units 15 30 24 35 95 23 18 15 Building with 5-19 units 1 197 33 208 48 44 59 176 Building with 20 0 193 0 328 57 583 37 539 Mobile Homes 2 0 0 0 28 0 3 0 Other Units 8 11 0 0 0 0 0 0 Total occupied housing units 3,428 588 6,199 719 7,161 934 7,497 1,207 Source:US Census&City of Chanhassen Building Permit Activity m C d c E 0 0 N C N n A 0 U 39 FIGURE 3-2 I HOUSING PERMITS ISSUED 2000-2016 Year Single Family Attached Single Family* Apartments Dwellings 2000 124 34 162 320 2001 85 44 100 229 2002 54 246 0 300 2003 59 94 243 396 2004 76 16 0 92 2005 60 24 0 84 2006 89 42 48 179 2007 65 86 18 169 2008 28 38 0 66 2009 71 14 0 85 2010 71 30 0 101 2011 106 62 0 168 2012 107 78 0 185 2013 89 86 0 175 2014 57 96 0 153 2015 80 24 0 104 2016 48 0 76 124 Average 75 60 38 172 Source:City of Chanhassen Since 2000 the city has grown from a Census estimated 6,195 owner occupied homes and 719 rental units to an estimat- ed 7,497 owner occupied homes and 1,207 rental units in 2015. *Attached Single Family homes are `Attached Single Family homes are multi-family homes in which one structure has several dwellings sharing a common wall or walls with another unit.Attached homes are different from apartment buildings in that they usually have fewer dwelling units, typically two to six, and are more likely to be owner occupied than rented. Examples include duplexes, townhomes, and row houses. Over the last 17 years, the city has approved the construction of an average of 172 dwelling units a year. During 2003, the city issued 396 permits, compared to 66 permits in 2008. The extreme variation between different years during this period is the result of it spanning both the height of the real estate boom and the subsequent economic recession.The five-year average of 148 permits a year represents the typical post-recession permit volume for the city.As of 2017, projections for the city's growth between 2017 and 2021 range from a low of 165 units a year to a high of 200 units a year. d a 1= 0 U N G 07 td .L" 40 3.1 .1 i Occupied Housing Units By Type and Tenure co FIGURE 3-3 12015 HOUSING UNIT TYPES FIGURE 3-4 12015 HOUSING TENURE Housing Type Tenure Single Family Multi-family Ownership Units Rental Units 8,180 1,276 8,186 1,270 Source:U.S.Census,Metropolitan Council Source:Metropolitan Council FIGURE 3-5 I HOUSING TENURE 2000 Housing Tenure ■Owner-Occupied t Renter-occupied ■Vacant 89 2015 Housing Tenure � 3-= t\ t d z 07 a Owner-Occupied N P Renteroccupied I i Vacant E 83 0 N a a L 0 k U Source:US Census(2000,10-year and 2015,5-year) 41 c Approximately 83% of the City's housing is owner occupied, down from 88% in 2000.

Many of these units are owner occupied townhomes, although some of these dwellings are being rented out. The city has also approved projects featuring multifamily dwellings during this period. Multifamily dwellings are defined as buildings with more than 5 units. These units include larger townhouses, condominiums, and apartments. Multifamily developments are generally rental properties; however, townhouses and condominiums can be either owner or renter occupied. Since the year 2000, the city has added 647 apartment units. 3.1.21 Owner Occupied Housing Figure 3-6 I AGE OF OWNER OCCUPIED HOUSING STOCK(SELECTED COMMUNITIES) Owner occupied Cities before 1950 1950-1969 1970-1989 1990-1999 2000-2009 2010-2014 Carver 109 39 119 275 509 166 Chanhassen 159 788 2,560 2,552 1,133 714 Chaska 306 419 1,749 1,910 1,797 i 364 Victoria 128 202 319 617 927 358 Waconia 203 459 364 1,005 1,127 365 Carver County 2,512 2,855 7,002 7,522 6,947 2,090 Sources:U.S.Census Bureau,Cities and Townships;Maxfield Research,Inc Over half of Chanhassen's housing stock was built after 1990.While Chanhassen's ratio of owner occupied housing built before and after 1990 is similar to Carver County as a whole,a significant portion of its housing stock is older than that of the other Figure 3-7 I MEDIAN RESALE PRICE(SELECTED COMMUNITIES) Cities Median Sale Price (Selected Communities) 2013 2014 2015 2016 Carver $282,500 $270,000 $277,750 $296,090 Chanhassen $303,500 $318,000 $325,000 $336,950 Chaska $251,000 $235,000 $255,000 $272,000 Victoria $371,500 $369,990 $403,250 $423,018 Q Waconia $229,000 $237,000 $250,000 $266,250 U Carver County $250,820 $258,050 $273,490 $279,900 C m Sources:Minneapolis Area Association of Realtors The above table includes the sales price of all detached single-family, attached single-family, and condominium style L. homes.

Once the data for detached homes, attached homes/townhomes, and condominiums is separated out, it is clear that the price of Chanhassen's detached single-family housing stock is increasing significantly faster than the price for attached homes/townhomes or condominiums. This discrepancy may be due to the fact that only 24 new attached-single family units and no new condominiums were constructed in 2015 and 2016, meaning that most of these sales involved the resale of older units.

Market rate rents in Chanhassen are higher than the rest of Carver County, for example, the median rent for a 2-bedroom unit in Chanhassen is$1,516.00 compared to$1,304 in Chaska.This discrepancy in rent rates is likely due to the fact that Chanhassen's rental stock has a significantly higher percentage of newer units than other communities in Carver County. Community Partners Research, Inc.found that with an estimated 1,270 rental units Chanhassen has nearly 19% of Carver County's rental stock. Only Chaska has a larger share of the County's rental properties. A phone survey conducted by Community Partners Research reported a 1%or less vacancy rate in Chanhassen's rental properties. Pervious work by Maxfield Research, Inc. in 2014 reported Chanhassen's vacancy rate as 2.90%; however, they found that the city's afford- able housing had a vacancy rate of 0%. Vacancy rates below 5% are generally considered to indicate unmet need for rental housing. 3.1.4 I Housing Condition Seventy-five percent of the Chanhassen's housing stock was constructed before 2000, and nearly two-thirds of the city's housing was built between 1980 and 1999. Using the city's property maintenance code,the city works with homeowners and property managers to ensure that this aging housing stock is safe and maintains its value. The property maintenance code establishes minimum requirements and standards for premises, structures, equipment, and facilities for light, ventilation, space, heating, sanitation, protection from the elements, life safety, safety from fire and other hazards, and safe and sanitary conditions.The ordinance also provides for administration, enforcement, and, when necessary, penalties for non-compliance. Maintaining existing housing helps to provide residents with an increased diver- sity of housing options. 3.1.5 Analysis of Existing Housing Needs The City of Chanhassen began first as a farming and then a bedroom community and has continued to evolve over the last 30 year. While the largest land use is low density residential the city has become a full service community. As the population ages and the industrial and commercial uses attract younger people,the demand for a wide variety of housing has emerged. The Metropolitan Council has designated Chanhassen as an Emerging Suburban Edge.The density requirements for this designation are overall average net densities of at least 3-5 dwelling units per acre in forecasted growth through 2040. The city has also provided sufficient high-density land use to potentially meet the goals of 806 affordable housing units. _a 3.2 Population and Income 1- Over the last decade, the city of Chanhassen's population increase just over 20 percent. The median age of the city in- creased 3.7 years and the household size has decreased by nearly 5 percent. l0 O U 45 3.2.1 j Demographic Changes Figure 3-13 I CHANHASSEN POPULATION BY AGE Chanhassen Populaiton by Age 2000 2015 Change Number % of Total Number %of Total Number %Change Age Under 5 years 2,020 9.9% 1,515 6.2% -505 -25.0% 5 to 9 years 2,227 11.0% 1,931 7.9% -296 -13.3% 10 to 14 years 1,889 9.3% 2,126 8.7% 237 12.5% 15 to 19 years 1,197 5.9% 2,102 8.6% 905 75.6% 20 to 24 years 590 2.9% 1,026 4.2% 436 74.0% 25 to 34 years 2,608 12.8% 2,370 9.7% -238 -9.1% 35 to 44 years 4,903 24.1% 3,348 13.7% -1,555 -31.7% 45 to 54 years 2,816 13.9% 4,839 19.8% 2,023 71.8% 55 to 59 years 732 3.6% 1,808 7.4% 1,076 147.0% 60 to 64 years 419 2.1% 1,173 4.8% 754 179.9% 65 to 74 years 591 2.9% 1,393 5.7% 802 135.7% 75 to 84 years 270 1.3% 464 1.9% 194 72.0% 85 years and over 59 0.3% 342 1.4% 283 479.9% Total Population 20,321 100.0% 24,437 100.0% 4,116 20.3% Source:US Census In 2015 the largest segment of the population (19,8%)was 45 to 54 years old. The median age of the city's residents is 39.2 years old, an increase of 3.7 years from the 2000 census's average age of 35.5. The average age in the metropolitan statistical area is 36.6 years, roughly unchanged from its 2000 average of 36.1 years. During this same period, the aver- age age in Minnesota increased from 35.4 to 37.7 years, and increase of 2.3 years.These different rates of increase are likely the result of millennials' preference for more urban environment, and Chanhassen's housing market being skewed towards executive/move up housing rather than starter homes affordable to younger couples and families.

Many of these couples desire tradi- tional detached single-family housing, and this demand has largely driven Chanhassen's housing market. The city's loca- tion in eastern Carver County and proximity to employment centers means that there will continue to be strong demand for single-family housing.

This decrease is partially explained by young couples choosing to have fewer children, average family size decreased by 3% over this period, and millennials choosing to delay starting families until later in life. Another contributing factor is the increasing number of empty nesters and widows/widowers. This trend of smaller house- £ holds and families is expected to continue as the population ages; however, Chanhassen's 2015 average household size 3 of 2.8 is significantly higher the metropolitan statistical area's average household size of 2.54. Due to Chanhassen's loca- tion in Eastern Carver County and its amenities, it is likely that the city will continue to attract a disproportionately larger share of the region's young families with children. w O U 47 2 FIGURE 3-16 ; 2016 ESTIMATES Chanhassen Population and Household Estimates Met.

The Metropolitan Council estimates that Chanhassen's 2016 population was 25,448 people in 9,267 households, which works out to an average of 2.74 people per household.* *The difference between these estimates and the numbers reported by the US Census is the result of the fact that the most recent census data available comes from the 2011-2015 American Community Survey 5-year estimates. This means that since data from 2011 to 2015 is averaged out to reduce the margin of error the census estimates likely underestimate the population and number of households actually present. The 2015 5-year estimates were used for the proceeding discussion because they provide more detailed data on age and house- hold composition and allow for direct comparison with previous years'census data. The Maxfield study examined the population's demographic trends and believes that following will be true in Carver County: u Households will increase faster than population as the overall population ages, couples will have fewer children, and single-person households will become more common. By 2040,they predict an average household size of 2.39 people. Caver County's house hold size decrease will likely be at a slower pace than other areas of the metropolitan statistical area. • Strong growth is expected across all age groups for the next 20 years, with growth in the number of 25 to 39 year olds fueling demand for single-family housing,town homes,and rental options. After 2030,the older adult population, 55+, is expected to increase rapidly, prompting an increased need for senior oriented housing. u People between ages 55 and 74 will experience the most rapid growth rates this next decade.The younger portion of this group is still looking for move-up housing, and are willing to consider alternatives to traditional single-family homes. • Western Carver County will likely have higher percentage of young families seeking affordable housing;whereas, communities in eastern Carver County will likely see a mix of senior, young adults, and older adults.These increases will be due to the aging of the existing population, young adults looking for rental housing near employment hubs, and older adults with greater means purchasing housing that is more expensive. Post 2030 adults ages 60 to 79 are expected to become the second largest age cohort, after adults 40 to 59 2.2.2 48 3.2.2 I Income Figure 3-17 I CHANHASSEN'S MEDIAN HOUSEHOLD INCOME BY AGE 2015 Median Household Income By Age Under 25 $53,472 25 to 44 $119,778 45 to 64 $127,852 65 and over $43,894 All Households $110,569 Source:American Community Survey 5-Year Estimates The U.S. Census estimates that Chanhassen's 2015 median household income was$110,569.

The size and composition of these new households will determine the composition of Chanhassen's housing market. 3.3.1 Residential Lands The city has approximately 1,200 acres of land guided for residential uses.The city projects that the majority of this land will be developed by 2030. It anticipates that land guided for single-family homes will initially be the preferred dwelling type, with an increasing share of multifamily housing developed as the city transitions from building out to in-fill/redevelop- ment. Most of the housing is expected to be market rate, though there is a strong demand for low-and moderate-income housing as well as senior oriented housing products. The Maxfield study had projected that the City would add 6,560 units of housing between 2014 and 2040. Since the study was commissioned, new information has caused the Metropolitan Council to revise its projections for the City's growth to down to 4,733 households.

The Metropolitan Council acknowledges that market conditions and development forces may mean that these units are not constructed; however, they require that cities demonstrate that they have sufficient land guided at high enough densities in order to accommodate these developments, should the opportunity emerge. The Metropolitan Council states that communities can meet this requirement by having a sufficient amount of land guided at a minimum density of 8 units/acre to meet its affordable housing need allocation.

The United States Department of Housing and Urban De- velopment establishes guidelines that determine if families qualify for subsidized affordable housing.

Federal guidelines state that —� a household spending more than 30%of its income on housing, including utilities, is cost burdened. Households spending more than 35% of their income on housing are considered severely cost burdened and may have trouble affording other essential goods like food and clothing due to the high proportion of their income going towards housing. Many subsidized housing projects either cap rents at rates that will not represent a cost burden to individuals making 80%AMI or limit the maximum rent tenants pay to 30%of their monthly income.

Approx- imately half of these cost-burdened households are renters, and renters over the age of 65 are especially likely to be z spending over 30% of their income on housing. a E 0 c� N C pN IA {O 1 55 F Figure 3-24 12015 AFFORDABILITY OF EXISTING HOUSING 2015 Existing Housing Assessment Affordable Level Units %of Units 30%or less AMI 151 1.60% 31%to 50%of AMI 936 9.90% 51%to 80%of AMI 1,950 20.60% Above 80%AMI 6,419 67.90% Total 9,456 100% Source:Metropolitan Council,Community Partners Research,Inc. Community Partners Research, Inc. estimates that Chanhassen has 3,037 dwelling units which are affordable to families making less than 80%of area's median income.The number of affordable units decreases significantly for households making less than 50%AMI. The Metropolitan Council evaluates cities based the amount of affordable housing they create and preserve. Chanhassen has a housing performance score of 35 out of 100(down from 45). This number is used to help prioritize the allocation of funding in the Livable Communities Demonstration Account and Tax Base Revitalization Account.The City's score has gone down due to the fact that no new affordable units have been constructed in the last decade. A lower score hurts the City's chance of being awarded money from these accounts and also impacts the City's score on requests for transporta- tion funding. Low scores also give the City preference for the Housing Incentives Account, in order to help Cities create affordable housing projects. While the city has created a small lot residential zoning district and uses Planned Unit Developments to encourage the construction multifamily housing,the high cost of land and construction costs mean that the city cannot provide the amount of assistance required to build new affordable housing. Using the above tools the city has been able to meet the density goals as shown on the City Plat Monitoring Sheet in Figure 2-30. 3.4.4 I Affordable Ownership Housing Figure 3-25 12015 AFFORDABLE OWNERSHIP FUSING 2015 Affordable Ownership Housing 30% 50% of 80% of AMI AMI AMI $85,500 $153,000 $240,500 Source:Metropolitan Council Affordable ownership housing is defined as housing that is affordable to buyers earning 80% of the area median income. , The Metropolitan Council equates this to a house priced at$240,500.The Community Partners Research, Inc. study s looked at all Chanhassen home sales, new and resale, and found that the 2016 median sale price for detached sin- gle-family homes was$420,000.The median price for townhomes was $228,250, and condominiums had a median price 8 of$166,500. The city's inventory of condominiums, attached single-family homes, and older detached single-family homes o means that there are opportunities for affordable homeownership; however,those opportunities become scarcer for indi- viduals earning less than 50%of the medium income. The majority of the city's existing affordable housing takes the form of ownership units.The map below shows the distribution of the City's ownership housing.Affordable ownership units tend to be found in the city's older subdivisions and new attached 75 housing developments.

Community Partners Research, Inc. estimated the city's 2017 median rents for one and two-bedroom units to be$1,387 and$1,516, respectively; however, a significant portion of Chanhassen's older rental stock is priced at or below the Metro Housing and Redevelopment Authority's guidelines. Despite the existence of lower cost rental units Community Partners Research, Inc. estimates that approximately 59% of Chanhassen's renters pay 30%or more of their income in rent, with the figure increasing to 92%for senior households. When all renter households were examined, they discovered that median percentage of monthly household income that went towards rent was 33%. By comparison, the County wide median was 27.8%.

The city has one publicly subsidized housing development,the Gateway Place, a 46-unit development which was funded by housing tax credits. Gateway Place's compliance period will end in 2021 and, unless relief is sought, its extended use period will last until 2036. The city's other subsidized housing development, Heritage Park, transitioned to market rate housing in 2004 when its housing tax credits' compliance period expired. The Centennial Hill development provides 65 units of affordable senior housing.These units are priced below market rate, and are subject income limits of 100%of area median income. Community Partners Research, Inc. reported rental rates ranging from$798 to$919 for one-bedroom units and$1,878 for two-bedroom units. Additionally, while The Summerwood project primarily provides market rate senior housing,the city created a TIF housing district to provide 32 affordable se- nior housing units.

Arbor Glen A 21 unit detached single-family development.The homes will be handicap adaptable, and the HOA will be responsible for all exterior maintenance. While not age restricted, this development is designed to provide housing options for older individuals looking to downsize and age in place. Avienda A 118-acre regional commercial/lifestyle center.This development will include up to 550 units of housing.The exact mix of this housing will be determined by the market; however, medium density single-family ownership housing and senior apartments with some level of service are the envisioned uses.This development was approved by the City Council on July 10, 2017. Mission Hill A senior oriented planned unit development with 8 independent living twin homes, 16 units, and a 136-assisted living unit senior housing apartment building.A daycare has also been incorporated into this building.The City Council approved this develop- ment on May 8, 2017. Powers Ridge A 76-unit market rate senior apartment.This is the third building of the Powers Ridge development which included four proposed multi-family buildings.The first two buildings were constructed in 2002. Venue A 134-unit market rate apartment in the heart of Chanhassen's downtown. These units will provide a walkable downtown rental option. This development also includes a 19,000 square foot retail space which will be occupied by Aldi.This devel- opment was approved by the City Council on July 10, 2017. West Park A 82-unit townhouse development featuring a mix of four-, five-, and six-plexs. These units are expected to be priced be- tween the mid $200,000 and the mid $300,000.These units will provide entry-level housing, and some units on the lower end of the price range may meet the region's criteria for affordable ownership housing. This development was approved by the City Council on July 10, 2017. E 0 C d w O U 60 Parking The city will continue to review new developments for adequacy of parking based upon need and the potential for joint use of parking facilities. Sufficient parking,transfer, and bus stop facilities should be provided to meet the needs of mass transit in major employment and commercial areas and in higher density residential and mixed use areas. Pedestrian/Bicycle Major activity centers should provide accessibility to pedestrians and bicycles including necessary bicycle parking facilities. The city will promote increased development of bikeways and trail facilities in order to conserve energy resources,enhance recreational opportunities, improve health, and assist in the abatement of pollution and congestion. Pedestrian and bicycle trails should be interconnected with major generators and have continuity across major roadways and other barriers. Sidewalks and/or trails should be required in commercial, industrial, and residential areas; adjacent to schools and other pub- lic buildings and along at least one side of collectors and other high volume roads. Other Mapped Road System.The city will utilize the land use plan and transportation plan maps to illustrate planned road alignments and to facilitate their acquisition and construction as new developments are proposed. The plan maps will illustrate all collector and arterial street alignments. They will also be revised from time to time by the city during the subdivision review process. Subdivisions.As a part of platting, each development should provide dedication and improvement of public streets consistent with the standards found in city ordinances. The city will promote the provision of street and pedestrian connections to maxi- mize safety and ease of access. Buffer.Sufficient setbacks and/or berming should be designed into all development projects adjacent to major pub- lic roadways. Capacity.Coordinate existing and planned transportation facilities and their capacities with land use types and densities with particular emphasis on land development in the vicinity of interchanges and intersections. Maintenance.The city will continue an ongoing maintenance program in order to maximize the community's investment in transportation facilities. Circulation. For proposed developments, the city will require detailed circulation and access plans which depict the impact of the proposed development on both the existing and future transportation systems. Arterial Deficiencies.The city will support Federal, State, Metropolitan, and local efforts directed toward the timely construc- tion of a new Minnesota River crossing connecting Trunk Highways 169 and 212, upgrading of TH 5 west of TH 41, re- alignment and construction of TH 101 south of Pioneer Trail, upgrading of TH 101 north of TH 5,TH 41, and other facilities serving the area. Chanhassen will coordinate efforts with Eden Prairie,Victoria and other appropriate jurisdictions to insure that TH 5 and 101 continue to function effectively. ;z E Construction and Maintenance. Chanhassen will coordinate the construction and maintenance of hard surfaced local streets, collectors,and arterials. Interconnect Neighborhoods. It is the city's policy to require interconnections between neighborhoods through the construction of local streets to foster a sense of community,to improve safety, encourage health and to provide a convenient access for ^� residents.

Goals = Provide housing opportunities for all residents, consistent with the identified community goals: Balanced housing supply, with housing available for people of all income levels. » Accommodation of all racial and ethnic groups in the purchase, sale, rental and location of housing within the community. » A variety of housing types for all people in all stages of the life cycle. A community of well-maintained housing and neighborhoods, including ownership and rental housing. Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. » The availability of a full range of services and facilities for its residents, and the improvement of access to a linkage between housing and employment. Policies Continue to enforce the City Code regarding property maintenance to maintain the existing housing stock. As state and federal funding permits, efforts should be made to provide low and moderate housing where needed,to provide balance to the generally high cost of new housing. • The city should promote the use of state and federal programs to reduce land costs for developers of low and moderate-income housing. » The city will cooperate with other governmental units and public agencies to streamline, simplify, and coordinate the ^� reviews required for residential development to avoid inflating the cost of housing due to unnecessary delays in the review process. • The city will continue to encourage the development of affordable housing; the city may increase the permitted net density of a project by 25 percent. The "bonus" units must meet affordable housing criteria as defined by the city. Developers shall be required to enter into an agreement ensuring the affordability of the units. Subsidized housing should be given equal site and planning considerations to non-subsidized housing units and should not be placed in inferior locations or in areas that do not provide necessary urban services including transit and commercial services. • The city will continue to provide alternative types of homes including smaller lot homes,townhouses, etc. that will supplement the conventional single-family homes. New residential development shall be discouraged from encroaching into natural resources or physical features. » Housing development methods such as PUDs, cluster development, and innovative site plans and building types, should be encouraged to help conserve energy and resources for housing. • » Citizen participation in developing plans and implementing housing programs is encouraged in redevelopment, rehabilitation, and in planning for the future. o » While density is given by a range in the comprehensive plan, the city shall encourage development at the upper end of the density range. • » The city will promote the mixing of housing densities within projects in order to provide a wide range of housing styles and types. Such mixed densities must provide appropriate transitions for existing development. -1 » The city will continue to participate in the Livable Communities Act of 1995 as stated in the Housing Plan. The city will promote the integration of life-cycle housing opportunities throughout the community.Affordable and subsidized housing shall not be overly concentrated in one area of the city. 68 3.7 Action Plan The city will continue to uphold the housing goals and policies of the comprehensive plan. The Following is the city's �- Action Plan: 3.7.1 i City Ordinance The city will continue to evaluate the existing development ordinance and its impact on development costs, especially the PUD ordinance and lot size/setback and design standards.

Goals = Provide housing opportunities for all residents,consistent with the identified community goals: » Balanced housing supply, with housing available for people of all income levels. » Accommodation of all racial and ethnic groups in the purchase, sale, rental and location of housing within the community. » A variety of housing types for all people in all stages of the life cycle. » A community of well-maintained housing and neighborhoods, including ownership and rental housing. » Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. » The availability of a full range of services and facilities for its residents, and the improvement of access to a linkage between housing and employment. Policies » Continue to enforce the City Code regarding property maintenance to maintain the existing housing stock. » As state and federal funding permits, efforts should be made to provide low and moderate housing where needed, to provide balance to the generally high cost of new housing. » The city should promote the use of state and federal programs to reduce land costs for developers of low and moderate-income housing. » The city will cooperate with other governmental units and public agencies to streamline, simplify, and coordinate the reviews required for residential development to avoid inflating the cost of housing due to unnecessary delays in --h the review process. » The city will continue to encourage the development of affordable housing; the city may increase the permitted net density of a project by 25 percent. The 'bonus" units must meet affordable housing criteria as defined by the city. Developers shall be required to enter into an agreement ensuring the affordability of the units. » Subsidized housing should be given equal site and planning considerations to non-subsidized housing units and should not be placed in inferior locations or in areas that do not provide necessary urban services including transit and commercial services. » The city will continue to provide alternative types of homes including smaller lot homes,townhouses, etc.that will supplement the conventional single-family homes. » New residential development shall be discouraged from encroaching into natural resources or physical features. » Housing development methods such as PUDs, cluster development, and innovative site plans and building types, should be encouraged to help conserve energy and resources for housing. » Citizen participation in developing plans and implementing housing programs is encouraged in redevelopment, rehabilitation, and in planning for the future. CD » While density is given by a range in the comprehensive plan, the city shall encourage development at the upper end 0 of the density range. The city will promote the mixing of housing densities within projects in order to provide a wide range of housing styles and types. Such mixed densities must provide appropriate transitions for existing development. » The city will continue to participate in the Livable Communities Act of 1995 as stated in the Housing Plan. » The city will promote the integration of life-cycle housing opportunities throughout the community. Affordable and subsidized housingshall not be overlyconcentrated in one area of the city. U 70 w n i' e n E 0 I U) a) " .Ce m Chapter4 cas \ A Y C."

Natural resources in the City of Chanhassen serve many purposes.They offer recreation on lakes,trails and parks, respite from busy lives, and remediation of development consequences.Collectively,the woods, wetlands, streams, rivers, and prairies contribute to a high quality of life for Chanhassen residents and visitors.The City of Chanhassen recognizes this important value and works to protect and enhance these natural features for the benefit of all.This chapter of the Compre- hensive Plan outlines accomplishments, challenges and future goals for the city's natural resources. In conjunction with ongoing development,the city has continued to make preservation of natural resources a priority.While directly improving the quality of life for Chanhassen residents, the city's natural resources also indirectly enhance this community by offering -� environmental benefits.Collectively, 'green infrastructure', such as trees, wetlands and open space, provides significant economic value by offering stormwater management, heat island reduction, erosion control, carbon sequestration, energy savings and increased property values. Protecting and enhancing the city's green infrastructure is an investment in the community's well-being as well as its future sustainability. 4.1 I Introduction As time goes on and communities grow and change, so too do their goals and challenges. For Natural Resources in Chanhassen,the emphasis has shifted to resiliency and sustainability from protection and documentation.While there are still open spaces that could become public amenities, management of the existing public lands has taken center stage and requires not only current responses but also long term planning. As the few remaining large pieces of private property are developed,the tapestry and function of the city's natural resources becomes solidified. Management and protection strategies are being revised to reflect the need for high-functioning natural resources that not only provide aesthetics and recreation, but also stormwater management, energy conservation and diversity.Valuable natural resources must also be functioning resources.Green infrastructure is now a necessary part of a well-managed community that brings tangible and intangible benefits to every facet of the community. Iv The natural resources challenges over the next decade encompass a broad spectrum,from localized invasive species a control to regional stormwater management. It will take vision and commitment to protect and enhance the natural re- sources in Chanhassen.The city's land use policies should recognize that natural areas and open space are long term uses in our community.The city's ordinances should reflect best management practices for trees,water, and soil.The city's goals and policies should serve to protect and enhance our natural resources. 4.2 I Urban Forests and Forestlands Chanhassen: meaning'tree of sweet sap'in the Dakota language.The Minnesota Land Survey of 1830 documented that a Chanhassen was located in the Big Woods,one of three major ecosystems in the state. 73 49 The trees were punctuated by wooded wetlands and open marshes around the many lakes. In time, the rich soil and plen- .' tiful timber gave rise to agriculture and development in the area. Much of Chanhassen, perhaps nearly all, was cleared of `-fh forests to create agricultural fields and homesteads. Along bluffs and in scattered remnants, the remains of the Big Woods c2 existed. Today, pockets of mature woods with sugar maple and basswood trees allow visitors to envision the historical Big Tsi Woods. Ownership of these remnant woods is today a mix of private and public. Camp Tanadoona and private property 4g to the west of Lake Ann, comprise the ownership of large tracts of high quality woods. Park land belonging to the City of ZChanhassen and Carver County encompass numerous acres of Big Woods and allow community members to be im- mersed in a wooded environment. While no one would consider Chanhassen to be 'urban', it does contain an 'urban forest'—the many trees that line our city streets, shade our playgrounds and parks, and dot the yards of every neighborhood.These trees make up a signifi- cant portion of the overall tree cover in the city. They provide multiple and important benefits to the health and economic viability of Chanhassen. Trees increase home values, decrease energy costs, reduce stormwater runoff, provide clean air, sequester carbon, keep people healthy, provide wildlife habitat and enhance community aesthetics.These benefits rise along with the percentage of canopy cover in a community. Currently,the city averages about 30 percent tree cover. Optimal tree cover depends on the intersecting aspects of costs, community desires and services provided by trees. Chanhassen has many opportunities to increase canopy cover throughout the city. At a minimum, the city should maintain the overall 30 percent cover and strive to increase it in specific areas that fall short. Currently the city benefits from city ordinances that require tree planting in new developments to assist in replacing lost canopy. Depending on the type of proposed development, tree preservation or replacement plantings in new construction must meet an overall canopy goal for the site. The percentages of cover range from 28 percent to 68 percent based on the existing conditions of the site and the Comprehensive Plan designation for the site.This ordinance is intended to maintain a minimum canopy coverage for the community. Other programs by which the city adds new trees to the community includes the annual tree planting program for Arbor Day and tree coupons given to residents. Programs such as these work to maintain tree cover, but more can be done. Planting trees to increase canopy cover must be a well-intentioned and well thought-out process. "The right tree in the right place" is not only a catchy phrase but advice that provides a long term return on the investment. Planting with the intention of seeing that tree grow to maturity and beyond is a cost-effective process that places trees suited to the specific environmental in the right places. There are several considerations to make when selecting trees and creating planting plans. Along with selections for height and size,the type of tree is also important. Species diversity will be the key to a sustainable urban forest. At a minimum, the city follows the 30-20-10 rule. No more than 30 percent of trees from any one family, no more than 20 percent of tree from any one genus and no more than 10 percent from any one species. In other words, no more than 30 percent of trees from the Betulaceae, or birch, family; no more than 20 percent of trees from the birch genus, and no more than 10 percent of trees should be paper birch species. A more conservative approach would be to reduce the quantity totals to 20-10-5.A diverse urban forest is more resilient to pests and diseases.An analysis of the current public tree inventory revealed that the city has overplanted ash and maples. Spruce trees are also too com- mon. Future plantings do not include ash trees at all and have very limited additions of maple trees as well. With the main- stay tree species selection out of the running, new choices need to be added. Climate change is promising to expand the z palette of tree selections by opening up lists of trees previously not cold hardy in Minnesota. These new selections will be necessary to maintain diversity for our city forest. L Additionally, planting specifications are important to the long term sustainability of the city's urban forest. If the tree is 8 planted improperly,then all the time, money and resources are wasted. Planting specifications that are up-to-date with current research and industry innovations need to be included in all public and private landscaping projects. Chanhas- sen's clay soils are unforgiving when it comes to planting depth. Planted too deep, a tree will struggle to thrive. Soil com- paction exacerbates the problem so in new developments it can often be challenging to maintain a healthy landscape. Planting specifications included on landscape plans for developments should include the best practices for planting �5 techniques and soil requirements.

All forestry activities need to be accom- plished with limited staff and budget. To date, the city has been able to adequately manage the urban forest but the time may be coming when the current staff and budget may not meet the needs of the community.This potential challenge of a valuable community asset may put our city trees at risk. The green infrastructure provided by our public trees in parks and along streets are a valuable resource that needs man- agement and attention just like our roads and pipes. Ensuring that our investments bring more returns than costs requires ongoing management and planning. The development of an Urban Forestry Management Plan would assist in organizing and prioritizing city tree work as well as forecast future needs and threats for the city. Currently, the city's public trees are managed through pruning and planting schedules as well as a continuously updated tree inventory. Having a manage- ment plan would serve to make public the city's best management practices for urban forestry as well as invite input for a future vision of the city's trees. 4.3 I Greenways/Natural Areas The Bluff Creek Corridor runs diagonally through the city connecting Lake Minnewashta with the Minnesota River.The 8 entire watershed of Bluff Creek lies within city boundary lines and because of this, the city had the opportunity to shape the development and protection of the creek.The creation of a green way along the creek has presented opportunities for valuable development and recreational activities.Trail users benefit greatly from the connected web of corridors following g Bluff Creek and its tributaries.There remains opportunities to connect areas in the watershed.These preserved pieces vary in quality but not in value.The city should maintain these greenways and natural areas for native plant and animal habitats. The city should also set a goal to limit fragmentation of natural areas and maintain green corridors that connect open space.

And yet, soil is treated at times as an easy thing to w manipulate, replace or remove. Construction activities that prepare soil for the addition of a road, house or other non-liv- ea ing, artificial surfaces do significant damage to this resource. Then sod and trees are placed into these sites and expect- ed to perform as though the activities never happened. Rarely, does this work out well.Visit most new neighborhoods and you'll find struggling young trees and overwatered turf.The city has recognized this negative result and now requires the replacement of 6 inches of topsoil on every lot in each new development. With this quality soil,water retention improves, roots grow better, runoff takes longer and money is saved through reduced water use and landscape replacement.To gain even better results, soil reconstruction should be done in areas of heavy compaction. Breaking up the soil and rebuilding it with compost and tree planting will provide optimal benefits to any site.The city should reassess what mea- sures could be taken during development to protect soils from compaction in the first place and rebuilding it when the protection isn't enough. 4.5 I Biological Diversity and Invasive Species The significance of conservation areas to plants and animals cannot be understated.Nor can it be for people,too,with valuable recre- ational and quality of life assets. Ideally,the City of Chanhassen should conduct a natural resource inventory.Currently,the Minnesota County Biological Survey Inventory done in 2000 is the only resources available to assist in documenting what environmental assets may be present.The city should commit to protecting and managing any rare species and unique habitats noted in the survey. A current map, produced by the U.S. Fish and Wildlife Service, of habitat areas of high potential for the rusty patched bum- ble bee includes Chanhassen. Not only is this an endangered species but also a pollinator, a group of insects that provide vital services to our landscapes and food production. Chanhassen has the opportunity to address and commit to pollinator friendly practices. Most neighboring communities have already adopted city policies that benefit pollinators while carrying no additional costs or labor. Chanhassen can help make an impact on protecting this crucial group of insects. �-- All of our natural resources are under threat from invasive species. Whether aquatic or terrestrial,these invaders wreak havoc on local natural areas and community budgets.The City of Chanhassen should continue to work to manage terres- trial and aquatic invasive species to the best of its ability. Protecting our natural resources from these threats may come at a cost but the benefit of healthy, sustainable natural areas translates into higher real estate values, reduced long term costs, greater quality of life, and more valuable natural assets.

To help facilitate this goal, ai ce the city's 7-member Environmental Commission is charged by the city council to promote and educate Chanhassen �v residents on the importance of natural resources. The volunteer commission works each year to provide opportunities for S co Chanhassen residents to learn more about the environment and become involved in the stewardship of it. City staff also Z endeavors to provide current,factual natural resources-related information to the public, utilizing various means of com- munication such as the Chanhassen Connection quarterly city newsletter and the city's website. The City of Chanhassen plans to maintain its current educational activities, as well as continue to expand its natural resources education program into the future. Future public education programs may focus on invasive species, water conservation, tree cover and diversity, and wildlife habitat. ARBOR DAY TREE TAGS JULY 4 RECYCLING/COMPOSTING is v .....9.

Making a community more resilient to these threats is a process of adaptation and planning. Resiliency is an ap- proach focusing on how well a community can respond to, and ultimately emerge from, climate change effects. One way zfor a community to increase its resiliency is by joining the GreenStep Cities program. Minnesota GreenStep Cities is "a vol- untary challenge, assistance and recognition program to help cities achieve their sustainability and quality-of-life goals." The requirements for becoming a recognized city vary according to the recognition level. To start, a city only has to pass a resolution committing to pursuing a Green Step City status. From there, cities will need to complete a certain number of action items to progress to a Step 2 or 3. The city of Chanhassen endeavors to become a GreenStep City and adopt best management practices throughout the organization that strive to plan for mitigation of and adaptation to climate change impacts. 4.8 Solar Energy Solar energy production dovetails into a community's resiliency goals. In Chanhassen, certain areas have high potential as solar generation sites as shown in the figure below.Areas that have low potential have inadequate access to sunlight. Factors such as tree cover and slope direction play a significant role in solar potential of a site. To accommodate private interests, the city does have provisions that allow solar panels on businesses and residences. The city recently bought into two community solar garden contracts. These agreements account for 30 percent of the energy purchased by the city. If desired, the city could purchase up to 110 percent of its energy from Community Solar Gardens.The agreements provide the city with significant cost savings into the future. �.

The city recognizes the importance of its natural environment to the quality of life for its citizens and the need to protect and enhance these resources. Policies Z u Preserve natural slopes wherever possible u Seek to connect natural areas whenever possible. Preserve wooded areas, plant communities, and native habitat whenever possible. Goal 2. Provide information and educational resources to improve knowledge and promote an active public role in management of natural resources. Policies Identify and provide information on invasive species on public and private lands, Revise city ordinance to include non-herbaceous and/or non-terrestrial invasive species as identified by the State. Establish and implement ongoing programs designed to educate land owners in sensitive water quality management practices and develop and maintain a public education program to promote reduction of nutrient and sediment loading into water bodies. Encourage residents and landowners to practice environmentally friendly lawn care and housekeeping practices, and to use native plantings or natural landscapes rather than turf lawns, where appropriate. Encourage the reduction in irrigation use. Promote the City of Chanhassen's Water Wise Program. >, Continue to provide opportunities for public involvement(e.g., neighborhood meetings, public hearings, mailed notices, etc.)for significant water and natural resource decisions or projects. • Coordinate and consult with the City Council and appropriate city commissions and committees on surface water and forestry issues. • Communicate with nurseries and garden centers, lake associations and other appropriate civic and citizen groups. Actively implement the current educational programs and work to develop and implement new education programs and activities related to natural resources. These programs will use a variety of media including use of notices, mailings, local cable television, newsletters, articles, websites, social media,workshops and/or presentations to inform and educate the public. Cooperate with the other agencies and encourage establishment of model interpretative sites for public education. Goal 3. Minimize soil erosion and sedimentation. Policies Continue to implement the erosion and sediment control policies and the construction site inspection program to ensure reduction of water quality impacts from lack of erosion and sediment control. o » Minimize disturbances to existing vegetation (trees,turf grass, native vegetation, etc.). Goal 4. Preserve and protect a variety of natural environments.

In the 2016 National Citizen Survey, residents indicated that 24 playground areas they highly value Recreation and Wellness opportunities in Chanhassen and ranked the city's health and wellness, recreational and fitness opportu- 17 picnic shelters nities, and preventive health services to be higher than other communities across the country.The survey also indicated that 9 out of 10 residents 5 swimming beaches frequently make use of the city's wide array of recreational opportunities. 15 tennis courts The Park and Recreation section of the 2040 Comprehensive Plan provides an overview and analysis of the city's existing system, identifies goals and 10 pickleball courts policies that will guide park and recreation decision making over the next 28 diamond fields 20 years, and establishes key initiatives that will complete and enhance the current system.

In addition to adding parks and trails to the system in conjunction with development,the community has supported major park improvement initiatives throughout the years. Three major bond referendums over the system's history have allowed for major parks and recreation improvements.The first bond referendum for parks was passed in 1969, resulting in the acquisition of Lake Ann Park, the beginning of the neighborhood park system; and the preservation of community character that is enjoyed by residents to this day. 1988 saw the second bond referendum, which funded phase two of Lake Ann Park as well as the purchase of park land in the southern half of the City. Another referendum was passed in 1996, resulting in: improvements in 18 parks system-wide; the construction of Bandimere Park; the reconstruction of City Center Park; preservation of over 40 acres of open space; and 7 miles of new community trails. 5.2 I System Components Today, the City's park and recreation needs are met by a combination of: city parks; city trails and sidewalks; school dis- trict facilities; private facilities; recreation programs; as well as non-city amenities including regional parks and trails and facilities in surrounding communities. Park Classification Park classifications are used to ensure that a park and recreation system has sufficient diversity and geographic distribu- tion to serve various neighborhood and community needs. Chanhassen's 30 parks comprise 888 acres of city land, pro- viding 36 acres of parkland per 1,000 residents.These parks fall into four classifications:community parks, neighborhood parks, special use parks, and preserves. Community Parks Community Parks provide opportunities for City-wide recreation and typically serve a 1-2 mile area.They emphasize active recreation by providing amenities like ball fields and soccer/football fields. Chanhassen's six community parks are t distributed throughout the city and most residents live within an easy drive or bike-ride.There is an anticipated shortfall in community park land after the year 2020. Since most of the new residential growth is anticipated to occur in two areas; g, south of Lyman Boulevard and on the west side of Lake Ann, it makes sense to look for new community parks in these areas Chanhassen currently has six Community Parks, including Bandimere Park, City Center Park, Lake Ann Park, Lake Susan Park, South Lotus Lake Park, and the Recreation Center. r U 89 0 Figure 5-1 I CITY PARK DISTRIBUTION 0 ''--- Greenwood, F-3 ...—..,, c 1 . c3 r Excelsior hwd _,....., t.. u..._ Minnetonka s oreoo ci (/) CU .-1C 0- CO 0- Cathcart Fri Mnoreas Ma City ol Shorermodl Min netonka swo / , v iii.

Chanhassen g operates under the standard that all residents should be within walking distance, or a half mile, of a neighborhood park. N The walking distance must also be free of major barriers like major roads or water bodies to count as adequate. Because acommunity parks often act as neighborhood parks for the people living in close proximity, a half mile radius is applied to a both neighborhood and community parks to identify any gaps in service. There are 23 Neighborhood Parks distributed throughout Chanhassen, 22 of which are City owned and operated. Cath- cart Park is located within Chanhassen and acts as a neighborhood park for residents north of Lake Minnewashta, but is owned by the City of Shorewood. Special Use Parks Special Use Parks are used to identify park facilities and amenities that target a specific user group and aren't associated with an existing park. Olson Community Garden is the City's only Special Use Park, and is an extremely popular amenity in the community. Preserves Preserves function to protect the City's high-quality natural space, and usually involve minimal low-impact development at most.The city currently owns almost 800 acres of open space protected throughout Chanhassen's fourteen preserves. These acres encompass a large portion of the Bluff Creek Corridor, as well as other treasured wetland and woodland areas. 5.3 Programming The City of Chanhassen offers a range of recreation and social programs for all ages.These currently include: crafts, dance, and sports for preschool aged children; crafts, sports, self-defense, ski and snowboards, and dance programs for youth; programs serving individuals with developmental disabilities and their families; fitness and sports programs for adults; community-wide events that occur annually; and educational programs, swimming, clubs,field trips, meal and driving programs for seniors. According to the Chanhassen Community Questionnaire, community events are the most popular type of programming of- fered by the city. Annual events hosted by the city and supported by area businesses include February Festival, Easter Egg /Candy Hunt, Arbor Day Celebration,July 4th Celebration, Fire Department Open House,Halloween Party,and Tree Lighting Ceremony.While these events are well-attended,there continues to be an interest for additional events throughout the year. The city has good working relationships with recreation groups and associations,who do a good job of providing a variety of programs.The city provides introductory level athletic programming for very young children (under 6)and team, league athletics(softball)for adults.There is a desire from some residents that the young athletic programming be improved in terms of structure and coaching. Additionally, interest has been expressed for more, older youth and adult programming in arts, fitness, and outdoor education.There is also desire from many residents for the City to provide programming, such as aquatics, to meet the needs of those who can't afford private facilities,such as Lifetime Fitness. 5.4 l Trails Chanhassen's 76 miles of trails have been identified as the most popular facility provided in the community.This city-wide a system helps connect neighborhoods to parks, schools, commercial and civic destinations, and adjacent communities. The City is committed to providing pedestrians and cyclists with safe crossings of major roadways, and today there is a pedestrian bridge over Highway 5 as well as several underpasses city-wide. Natural surface trails are present in Fox Woods Preserve, and desire has been expressed to expand this network to create more low-impact connections between residents and natural areas. Several regional trails connect Chanhassen to surrounding communities and destinations, including the Lake Minnetonka LRT Regional Trail to the north and the Minnesota River Bluffs LRT Regional Trail to the south which has a parking area and trail head area off of Bluff Creek Drive. C) 91 Both of these trail corridors are owned by the Hennepin County Regional Railroad Authority(HCRRA)and are slotted for �L- future light rail transit use. A cooperative agreement between HCRRA and Three Rivers Park District allows the corridors ''1 -a to be used for interim recreational purposes. Figure 5.2 displays the City's existing system of trails and sidewalks. In 5.5 ( Notable Facilities a City Recreation Center The Chanhassen Recreation Center provides the community with year-round indoor and outdoor recreational facilities.The Recreation Center is a focal point for many of the city's community events and recreation activities and programs.The staff at the Recreation Center takes pride in providing a fun and friendly atmosphere for people of all ages at an affordable price. Facilities at the Recreation Center include a gymnasium,fitness room, aerobics/dance studios,five meeting rooms,and out- door ball fields,tennis and pickleball courts,and hockey/inline skating rinks. Due to the popularity of the programs(especially dance)and the lack of meeting space throughout the community,the Recreation Center is often completely rented out. Senior Center Chanhassen's Senior Center is a popular and highly utilized amenity for retirees, and is centrally located within the City Hall. The Senior Center provides senior programming including woodcarving, field trips, art and education classes, health and wellness programs, and card playing. Non-City Facilities There are several non-city recreation facilities located in Chanhassen.The locations of these facilities are highlighted in purple in Figure 5-1. Schools(ISD 276&112) The public schools in Chanhassen partner with the City to offer facilities for public use outside of school hours.The city has agreements for shared use at Chanhassen High School for school athletic fields. Bluff Creek Elementary School shares facilities with Chanhassen Recreation Center,while Chanhassen Elementary School shares facilities with City Center Park. While there is not a specific shared use agreement, Minnetonka Middle School West's facilities assist in addressing needs for surrounding residential neighborhoods. Lake Minnewashta Regional Park This 330 acre Regional Park on the east side of Lake Minnewashta is owned and operated by Carver County with sup- port from the Metropolitan Council. Facilities include: lake access, a fishing pier, picnicking, sand volleyball, a swimming beach, and trails. A new off-leash dog area was established in partnership with Carver County,the City of Chanhassen, and the City of Shorewood Parks Foundation. A fee is required for use. Camp Tanadoona Camp Tanadoona was started by the Minneapolis Camp Fire Girls in 1924 and consists of 63 acres of land on Lake Minnewashta, south of Lake Minnewashta Regional Park.Today the camp serves both boys and girls and offers overnight and day camps. MN DNR Lands 0 The Minnesota Department of Natural Resources protects several areas of land within Chanhassen.An 8 acre parcel on athe east side of Lotus Lake is preserved as open space.The DNR also owns 106 acres of the 600-acre Seminary Fen wetlands complex in southern Chanhassen,which contains a Scientific and Natural Area(SNA)that encompasses 73 s acres and protects a rare calcareous fen and threatened plant species.The remaining 33 acres were allotted to the adja- --� L cent Raguet WMA. Finally,the DNR owns public land surrounding Lake St.Joe,which is just south of Roundhouse Park in .6 northwest Chanhassen.

While some areas of the refuge -6 have trails and interpretive signs, there are no public recreation facilities in Chanhassen. a Raguet Wildlife Management Area (WMA) The Raguet Wildlife Management Area encompasses 270 acres, 190 of which are located in Chanhassen.The WMA is entirely within the floodplain of the Minnesota River. Natural communities include floodplain forest, wetland areas, and grassland.The management emphasis is maintaining and improving habitat for wetland species.The only public recre- ation access is for hunting. The Minnesota Landscape Arboretum The Minnesota Landscape Arboretum is a 1,000 acre facility, 675 acres of which are located in west Chanhassen.The Arboretum is a unit of the University of Minnesota and is a public botanical garden and an education and research institu- tion. It features display gardens and exhibits, model landscapes, restored native landscapes, plant research plots as well as extensive plant collections, and hiking and cross country skiing trails. Educational offerings include children's pro- grams, family activities, adult education, therapeutic horticulture, and the Anderson Horticultural Library.The Arboretum hosts several public festivals every year as well.

By building flexibility into the city's recreation and park facilities by considering the implications of trends, Chanhassen will be able to adapt quickly and efficiently in order to meet these new demands. The following trends are relevant to the future of Chanhassen's parks and recreation: » Desire to create more memorable experiences » Increased importance of'place' » Desire for conservation & natural connections » Demand for green alternatives » More transient » Pinched government budgets » Increased interest in aging actively » Engaging new generations » Increased interest in weight loss&active living » Rise in informal adult recreation versus league participation N » Popularity of new&nontraditional sports » Demand for group fitness events&races » Need for convenience » Increasingly anxious about safety 94 5.7 Needs Assessment Key Findings •L To understand the state of Chanhassen's Park and Recreation System, the system planning process involved conducting -0 a critical evaluation of the city's existing conditions, peer communities, nation standards and trends, best practices, and community input.These analyses identified current and future needs and desires, which subsequently guided the devel- 4 opment of guiding principles and goals, policies, and initiatives that work together to guide the future of the system. The evaluation process included: • Meetings with the City Staff, Advisory Committee, Park Board, and the City Council Two phases of community input to gather feedback on existing conditions and future desires -Seven Community Pop-Up Events - Athletic Association Stakeholder Meeting -Senior Stakeholder Meeting -Three Online Community Questionnaires -Two Online Social PinPoint Maps -Community Open House • Evaluation of the entire system of parks, trails, natural resources, connectivity, programs, and facilities including an update of the Park System Inventory Demographic analysis • Evaluation of current park classification system and standards » Evaluation of service areas, future growth,and development needs » Identification of issues and opportunities at a system-wide level Comparison of existing supply, quality, and distribution of features and facilities to national standards and to peer communities u Evaluation of emerging trends influencing future needs of the system The following are key findings that summarize what was learned throughout the needs assessment process. Parks » Chanhassen's 30 parks provide about 36 acres of parkland per 1,000 residents,which exceeds the national standards as well as that of surrounding communities.With the expected population growth of over 10,000 new residents in the next 10 to 20 years,the city should continue to look into expanding the number and distribution of parks as opportunities arise. Emphasis should be placed on currently underserved areas, as well as future areas anticipated to be developed with medium and high density housing. Partnerships with school district have contributed positively to availability of facilities and efficiency of operations. » At existing parks, user amenities like lighting, benches, grills, witi, and permanent restrooms were suggested as potential improvements Facilities u Chanhassen currently provides a diverse,well-distributed range of park and recreation facilities. • The amount of playgrounds in Chanhassen is consistent with that of surrounding communities, and is within an acceptable range for anticipated population growth. GO u A desire of the community identified in the engagement process was for the inclusion of natural playscapes,which 2 are play areas either made with natural materials or made to look like nature. The incorporation of natural playscapes 2 can be addressed through replacements, upgrades, and when new construction occurs. o U 95 The City has sufficient traditional athletic facilities, like diamond fields (baseball, softball)and rectangular fields F6 (soccer,football, lacrosse),for both current and projected population figures. However, an analysis of field sizes finds that many of the existing diamond and rectangular fields are not large enough for adult games so ensuring a mix of field sizes is an important consideration moving forward. Future development should consider how to cn -6 serve areas in the north, south, and west not otherwise served by non-city facilities. cts a During the community engagement process, residents expressed a desire for amenities that improve the quality of their playing and viewing experience.This includes lighting, permanent restrooms, and seating. » Informal sport facilities, like tennis, basketball, sand volleyball, pickleball, and open fields, are well-distributed throughout the community. » While the amount of aquatic facilities is on par with those of surrounding communities,though all of the facilities are beaches.The community has expressed a strong desire for additional aquatic facilities like an outdoor pool, an indoor pool, and splash pads. The Recreation Center and Senior Center provide year-round, indoor recreation opportunities.Community input has indicated that the current facilities are not sufficient. Residents desire a signature recreation facility that provides indoor facilities like a running/walking track,a larger fitness center,an indoor/outdoor pool, meeting spaces,family activities,and additional fitness classes.Additionally, interest was expressed in improving the Senior Center by expanding awareness and adding more active recreation offerings, fitness facilities, and meeting spaces. » A key focus over the next 20 years should be the maintenance and replacement of aging facilities. Preserves and Open Space Most residents are happy with the amount of perceived natural open space throughout the city and many would support additional preservation. --1 While the vistas created by open space are valued, desire was also expressed for increased access so users could better experience natural areas, particularly around Lake Ann and within the Bluff Creek Corridor. Trails » Chanhassen's 76 miles of trails have been identified as the most popular facility provided in the community. » Safe crossings were a topic discussed throughout the system planning process. Currently the city has a pedestrian bridge over Highway 5 as well as more than ten underpasses city-wide. » In addition to safe crossings,trail users requested additional amenities to improve their trail riding experience. These requests include benches, wayfinding, and lighting to enhance safety and extend year-round use. » Currently there are natural surface trails in Fox Woods Preserve, Carver Beach Park, Lake Ann Park, Carver Pond Park, and Stone Creek Park. Community members expressed a desire for additional natural surface trails, particularly as a way to further explore natural areas,whether in preserves or parks. Programming The City of Chanhassen offers a range of recreation and social programs for all ages.There is a desire from some residents that the young athletic programming be improved in terms of structure and coaching. Additionally, ointerest has been expressed for more older youth and adult programming in arts,fitness, and outdoor c' education.There is also desire from many residents for the city to provide more programming, such as aquatics,to meet the needs of those who prefer public recreation programs. According to the online system-wide questionnaire performed in Fall of 2016, community events are the most popular type of programming offered by the city. While these events are well-attended, there continues to be anCO --� interest for additional events throughout the year. 15 The city has good working relationships with recreation groups and associations,who do a good job of providing a variety of programs. 96 » Improved amenities that support events, like picnic shelters with amenities to support food preparation, would help cn encourage existing and future programming. `-- Management and Operations co » There are concerns about deferred maintenance issues, especially in small neighborhood parks H (playgrounds, basketball courts, hockey rinks). a » Concerns also existing surrounding the maintenance of natural resources and lake water quality. » Ongoing investments will be required to maintain the quality of the existing system into the future. 5.8 I System Plan The system plan recommendations were drafted based on the findings from the needs assessment, peer community and national standards analysis, community input, review of the previous Comprehensive Plan,Advisory Committee discussions, and meetings with City Staff.The recommendations are organized into goals, policies,and strategies.Goals are broad state- ments that describe the desired long-term outcomes needed for the system's guiding principles to be achieved.The next level, policies, are statements that will guide City decision-making to achieve the goals. Policies are followed by initiatives, which describe the specific actions or steps that need to be taken.To support and further clarify the initiatives, maps have also been attached to illustrate recommendations relative to parks,facilities, preserves, and trails.A set of precedent imag- ery has also been prepared to help illustrate what some of the proposed new facilities may look like. Vision &Guiding Principles As the City of Chanhassen develops and changes over the course of the next 20 years, its Parks and Recreation System must likewise evolve. New opportunities will present themselves, as will new challenges. Sustaining a desirable park and recreation system through this evolution will require a set of guiding principles based on the Community's shared vision. These Guiding Principles provide an over-arching framework that informs the development of specific goals, policies, and initiatives.They are also a tool for future decision-making, serving as a yardstick to measure the results of this plan and the appropriateness of future initiatives. Stewardship Stewardship is one of the hallmarks of Chanhassen's Parks and Recreation System. An extensive network of preserves gives residents the opportunity to explore and learn about Chanhassen's rich web of natural resources. Greater aware- ness of Chanhassen's prairies, wetlands, lakes, rivers, forests, and wildlife has led to a greater understanding of the role those resources play in making the community a great place. Chanhassen's citizens have embraced their role as stewards of their city's natural resources. They understand the need to conserve Chanhassen's natural resources so they will contin- ue to enrich future generations, and they advocate continuing to incorporate sustainability practices such as sustainable design, native plant diversity, and ecological maintenance into the system's planning and daily operations. Connectivity Connectedness is at the heart of Chanhassen's Parks and Recreation System. The system itself is connected; its parks, preserves, and trails knitted together to create a network of recreation and open spaces that reaches every corner of the community. This network connects residents, neighborhoods, and destinations to one another, strengthening the corn- munity and enabling all to enjoy safe, easy, and convenient travel throughout the community and to neighboring cities. Likewise the system's facilities and programs not only connect residents to one another, but they also connect residents to g the outdoors and to Chanhassen's wealth of natural resources. 0 Engagement $ Chanhassen's Parks and Recreation system welcomes residents of all ages and all abilities,enabling them to lead active, healthy lives in which they engage with the outdoors,with art and culture,and with one another. Partnerships with private I entities,neighborhood and community organizations,athletic associations, user groups,businesses,and schools have cre- ated a sense of shared ownership and pride across all segments of the community, leading to active participation in system o planning,operation,and maintenance.The system's high quality facilities and programs are a source of community pride that e inspire life-long discovery, learning,and socializing. 97 A Adaptable i As Chanhassen has evolved, becoming a larger, more economically and culturally diverse community, its Parks and Rec- c reation System remains adaptable in the way it responds to new needs and challenges,and dynamic in its ability to deliver high-quality programs,facilities, and services. Increased partnerships with groups, organizations, and businesses repre- senting all segments of the community have resulted in new and diverse sources of funding and an infusion of new ideas, n- energy and enthusiasm. These partnerships have increased the system's versatility, enabling staff and volunteers to adjust to lifestyle changes, respond to new trends, and enhance the system's quality and efficiency. Goals & Policies The System Plan's goals and policies are high-level statements intended to guide city decision-making over the next 20 years.The six goals represent the desired long-term outcomes of Chanhassen's System Plan, and were prepared as depic- tions of how the Parks and Recreation System will function when the guiding principles are achieved.To guide city deci- sion-makers, the general characteristics of each goal are described by a series of policies. In the System Plan hierarchy, goals are the highest level and are numbered 1-6, while policies are numbered 1.1, 1.2., etc. so it is clear to which goal a specific policy relates. Goal 1. Provide a comprehensive system of park, recreation, and open space facilities to serve active and passive needs. 1.1. Provide a system that includes neighborhood parks, community parks, preserves, and special use parks based on the standards outlined in Table 6-1. 1.2. Ensure residents have convenient access to park and recreation facilities at the neighborhood and community park level by ensuring all residents are within a Y mile of a neighborhood park and 2 miles of a community park. 1.3. Provide a mix of athletic complexes with user amenities to meet the needs of recreational, league, and tournament play. 1.4. Provide user amenities as appropriate for the type of park 1.4.1.To serve local users walking or biking to their neighborhood park, provide user amenities like benches, bike racks, shade trees, trash and recycling receptacles, and seasonal restrooms. 1.4.2.To serve community and regional users, provide at community parks amenities like benches, picnic tables, bike racks, information kiosks, shelters, permanent restrooms,trash and recycling receptacles, and access to technology. 1.5. Balance the use of park and recreational facilities for local needs with events,tournaments, gatherings, and programming. 1.6.

Provide areas for small and large group community gathering through the distribution of shelters in neighborhood and community parks. 1.9. Seek opportunities to distribute separated, 2 to 5 year old playgrounds throughout the community. Goal 2. Maintain a comprehensive and easily navigable trail and sidewalk system that connects neighborhoods to park and recre- ation facilities, schools, community destinations, and other communities. 2.1. Prioritize the elimination of trail gaps based on safety, connectivity, and cost. 2.2. Create trails within preserves. 2.3. Improve the trail user experience through improved maintenance, wayfinding, and amenities (i.e. benches, trash cans, etc.).neighborhoods to enhance connections to surrounding amenities. 98 Figure 5-3 I REGIONAL TRAIL SEARCH CORRIDORS u) •L `' 2040 REGIONAL TRAIL SEARCH CORRIDORS ID CU The Metropolitan Council has to create connections between been identified,the specific alignment N established general search corridors regional parks and trails.The map of the regional trails will still need to a for new regional trails or extensions below displays regional trail search be determined through a planning of existing regional trails.These corridors that intersect with the City process led by the regional park corridors were designated in order of Chanhassen.While corridors have implementing agency.

Transportation ,_.2 6.1 I Introduction a The City of Chanhassen is located in northeastern Carver County approximately 20 miles from downtown Minneapolis. It is classified as an emerging suburban edge of the Twin Cities Metropolitan Region, and is anticipated to be fully developed by the year 2040.

CIO Several regional highways provide Chanhassen with accessibility to the metropolitan area and to out state Minnesota. These include Minnesota Trunk Highway(TH)5 which runs east/west and interchanges with 1-494 east of Chanhassen in the City of Eden Prairie;TH 7 which runs east-west along the northern border of Chanhassen,TH 41 which runs north- I south through the western portion of the city,TH 101 which runs north-south bisecting the southern portion of the city and r defining the northeastern border of Chanhassen with Eden Prairie and U.S. Highway 212 which traverses the southern E third of the city. 0 The Chanhassen Transportation Plan is based on the city's 2040 Comprehensive Plan update and incorporates the Land g Use Plan to evaluate and direct the local transportation system. Updates to these plans have been undertaken by the w city to recognize changes in land use, development patterns and other planning processes including: the Minnesotaik Department of Transportation's "The 20-Year Minnesota State Highway Investment Plan" (MnSHIP),which directs capital investment for Minnesota's state highway system. The plan must identify investment priorities given current and expect- o ed funding. It is updated every four years, as required by the Minnesota Statute. This MnSHIP update spans the 20-year z. planning period from 2018 to 2037. The Statewide Multimodal Transportation Plan describes statewide objectives and 109 strategies that help MnDOT and its partners make progress toward the Minnesota GO 50-Year Vision, Carver County's Transportation Plan 2014 update and the Metropolitan Council's 2040 Transportation Policy Plan (TPP)and Thrive 2040 a MSP. The TPP was adopted on January 14, 2015 and outlines major transportation investments for the transportation c system in the seven county metropolitan area. The TPP identified $84 Billion (2015-2040) in the Current Revenue Scenar- co io for transportation needs in the region. As a result of this funding level, many needs throughout the metropolitan area will go unmet over the next 20 years. The TPP identified current Level of Service(LOS) problems on regional routes such as TH 5, TH 7, TH 41, TH 101 and U.S. Highway 212. Given these limited capacity improvements to regional facilities, operational(congestion), and safety problems on these facilities will continue to increase. Since the regional facilities are anticipated to function poorly, additional traffic is anticipated to divert to the local system. Carver County is in the process of updating their Comprehensive Plan including the transportation element. System changes and traffic forecasts included in this plan are based on county facilities and forecasts. Study Goals and Objectives The Transportation Plan shows how the City of Chanhassen will achieve its goal of creating an integrated, multi-modal transportation system,which permits safe, efficient and effective movement of people and goods while supporting the city's development plans and complementing the metropolitan transportation system that lays within its boundaries.To accom- plish this goal, the Transportation Plan: • Identifies the density and distribution of future land uses and their relationship to the proposed local transportation system and the anticipated metropolitan transportation system. » Develops a functional hierarchy of streets and roads and defines their access to the regional system to ensure that they support the existing and anticipated development of the area; serve both short trips and trips to adjacent communities; and complement and support the metropolitan highway system. » Establishes a system improvement and completion program that ensures that higher priority projects are constructed first; maintains a consistent and coherent roadway system during the roadway system development process; and provides for adequate funding for all needed improvements. » Identifies what transit services and travel demand management strategies are appropriate for implementation in Chanhassen in order to increase the number and proportion of people who use transit or share rides, and reduce the peak level of demand on the entire transportation system. • Identifies the strategies and policies that need to be implemented to properly integrate the trail system (pedestrian, bicycle, etc.)with the proposed roadway system, to ensure the provision of trails in a sequence consistent with the development of the roadway system, and to create a rational network of sidewalks. Because this analysis deals not only with streets and highways, but also with land use, trails, transit, traffic management and other topics, the results will constitute a Transportation Plan.The plan will serve as the Transportation Element of the Comprehensive Plan. z 6.2 land Use Existing Land Use n rExisting development within the city is influenced by several factors including the relative location of the Minneapolis Cen tral Business District, the location of metropolitan highways and the location of several lakes within the city. Residential development, which previously has occurred primarily in the northern portion of the city, with some large lot developments E. in other areas, has begun to spread out throughout the city. Commercial areas in Chanhassen have developed along the major highway corridors of TH 5 and TH 41. Additionally, a lifestyle center is under development at the intersection of U.S. Highway 212 and CSAH 17(Powers Boulevard). The city is also planning for a mixed use development in the CSAH "a 61 corridor in southern Chanhassen with the extension of urban services. For more information on land use with in the C. city see the land use section of the comprehensive plan. 110 Metropolitan Urban Services Area The Metropolitan Urban Services Area(MUSA) is defined as areas within the city that may be served with centralized infrastructure service and which may therefore develop at urban densities and intensities. The purpose of this boundary N is to define the areas within the Twin Cities Metropolitan Area that are eligible for "urban services", specifically sewers, municipal water systems and particular types of transportation systems. This boundary line is defined and maintained by H the Metropolitan Council to assist in the orderly development of the metropolitan area. The city has identified the key infrastructure, lift stations, wells and streets needed to expand into the 2020 MUSA area. It is the city's desire to direct development to those properties that have municipal services. Assuming that current devel- opment patterns continue, the majority of the city will be developed by 2040. The pace of expansion of the MUSA will depend on availability of sufficient developable land to support the required infrastructure. The location of the MUSA line is, therefore, a valuable guide in determining the priority of roadway improvements. The roadway system within the MUSA area is going to be in demand much sooner than the roadway system outside. This is one of the reasons for having such a boundary. It allows municipalities to focus limited resources on particular parts of their territory. All of Chanhassen is expected to be within the MUSA by the year 2020. However, the actual extension of urban services will be dependent on the orderly construction of key infrastructure. Land Use Plan The 2040 Comprehensive Land Use Plan defines areas where the city will encourage specific types of land uses to be de- veloped. The general categories of land uses defined by the city are residential, commercial, mixed use, industrial, office, public and parks. The Land Use Plan is a tool that the city uses to "guide" future development so that it is consistent with current and future land uses in the city. From these land uses, the socioeconomic projections are estimated. Socioeconomic Characteristics -� The analysis and projection of regional traffic conditions is conducted utilizing a technique known as traffic analysis zones. Traffic analysis zones(TAZ)are defined geographical areas within which data such as population,employment and household information is collected. This data is analyzed through computer modeling techniques which results in forecasts of traffic movement between zones. Utilizing this technique, it is possible to project travel and demand such as person trip productions, person trip attractions, intrazonal person trips and motor vehicle data such as average daily trips and peak hour trips. This data is valuable in both local and regional transportation planning. Table 6.1 shows the past census population, households, and employment as well as 2020-2040 forecasts for the City of Chanhassen. From 2010 to 2040, the population and the number of households in Chanhassen are projected to increase 62 percent. By 2040, Chanhassen's employment is projected to grow 61 percent more than the 2010 figure. City fore- casts are based on the location of existing development and an understanding of the kind of development that occurs as well as the rate at which development is occurring both within Chanhassen and throughout the region.

A good indicator of existing need is traffic congestion. However, L maintaining system continuity as new land develops is also important. Identifying future need requires an understanding 1 of how the city is expected to grow. The preceding section outlined the expected distribution of housing, population and employment. Traffic forecasts were made for the existing roadway system including improvements that are already programmed. This traffic analysis allows the detection of problems that would develop if no further system improvements were made. Existing Roadway System As with all municipalities,jurisdiction over the roadway system is shared among three levels of government: the state, the county and the city. The Minnesota Department of Transportation (MnDOT)maintains the interstate and trunk highway system on behalf of the state; Carver County maintains the County State Aid Highway(CSAH)and County Road systems. The remaining streets and roadways are the responsibility of the city. The existing street network includes approximately 153 miles of road. This represents double the road system of 75 miles in 1990.

These volumes represent aver- cn = age daily traffic volumes and are shown on the Traffic Volumes Map. Existing Transportation Issues/Deficiencies The function of a transportation plan is to not only accommodate future needs but also to analyze existing problems and pose appropriate solutions. Frequently, existing problems are closely related to future needs. As a result, a specific ac- tion in a given area can remedy existing deficiencies while providing for future needs. Issues and system deficiencies were categorized into three areas: 1) intersections, 2) roadway capacity/alignment/con- nection and 3)jurisdictional continuity. The major issues are shown on the system deficiency map and discussed in more detail as follows: a E 0 V d M V 116 Figure 6.3 I TRAFFIC VOLUMES MAP = ..' , Existing and 2040 Traffic Counts 5. ir1011 - in the City of Chanhassen = ( .�! act 1.

A summary of the intersections that experience the most problems are as follows: N • TH 7/Minnewashta Parkway-The major problem with this intersection is the angle with which northbound Minnewashta Parkway joins TH 7. As a result, it is difficult to see eastbound traffic on TH 7. Also, turning movements from eastbound TH 7 to southbound Minnewashta Parkway are cumbersome. Due to heavy traffic volumes, particularly during peak hours,turning movements in this area are difficult. Installation of a traffic signal at this location may be warranted in the future. TH 5/Minnewashta Parkway-The City of Chanhassen completed improvements to Minnewashta Parkway in 1993. A pedestrian underpass was constructed to the Minnesota Landscape Arboretum in 2012. Due to heavy traffic volumes, particularly during peak hours, turning movements in this area are difficult. Installation of a traffic signal and turn lanes at this location are anticipated in the future. » TH 5/Crimson Bay Road/Minnesota Landscape Arboretum entrance- Due to heavy traffic volumes, particularly during peak hours, left turning movements in this area are difficult. Elimination of left turns may improve this intersection. » TH 41/Lake Lucy Road. Due to heavy traffic volumes, particularly during peak hours on TH 41, turning movements in this area are difficult. Installation of a traffic signal at this location may be warranted in the future. » TH 41/W. 78th Street-Due to heavy traffic volumes, particularly during peak hours,turning movements in this area are difficult. Installation of a traffic signal at this location may be warranted in the future. • TH 5/TH41 - Intersection geometrics were evaluated. Additional turn lanes and through lanes are necessary on TH 41. The south approach to the intersection contains a significant slope that must be lowered. • TH 41/Water Tower Place-A future right-in/right-out has been planned for this intersection. Installation of this intersection is not possible until the roadway geometrics are improved south of TH 5. Improvements to TH 41 are not in the 20 year MnDOT improvement plan. Galpin Boulevard/Lyman Boulevard-With the development of the property south of Lyman, a fourth traffic leg will be added to the intersection. TH 5/Powers Boulevard (CSAH 17)-Traffic congestion occurs at this intersection during peak hours.Additional turn lane improvements are required on westbound left turn movements. » Market Boulevard/Market Street-Due to heavy traffic volumes, particularly during peak hours,turning movements in this area are difficult. This intersection will need to be monitored to determine if improvements are warranted. » Great Plains Boulevard/W. 79th Street-This intersection includes failing level of service levels for left turning movements.This intersection will need to be monitored to determine if improvements are warranted. TH 101/Pleasant View Road - Due to heavy traffic volumes, particularly during peak hours,turning movements in this area are difficult. Installation of a traffic signal at this location may be warranted in the future. Turn lanes were added to this intersection and a pedestrian warning light(rectangular rapid flashing beacons)was installed in 2015. » TH 101/Kurvers Point RoadNalley View Road- Due to heavy traffic volumes, particularly during peak hours, turning movements in this area are difficult. A southbound by-pass/left turn lane is provided at this intersection. o. This intersection will need to be monitored to determine if improvements are warranted. TH 101/Flying Cloud Drive-The city, in conjunction with Carver County and MnDOT,will undertake a study to determine the appropriate access controls necessary to serve the properties and maintain the capacity of Flying Cloud Drive. In 2016, a roundabout was constructed at the intersection of Flying Cloud Drive and the CSAH 101 river crossing. It the future, the north leg of the intersection realigning TH 101 will connect to the roundabout. O U 119 Road Capacity/Alignment/Connections Deficiencies in this category are mainly caused due to capacity problems created by increased traffic volumes, alignment Nor geometric deficiencies or poor regional or local connections. Examples of such circumstances include the following: cc �`- TH 5 Users of TH 5 are aware that excessive congestion on this route occurs at various times of the day with concentrations during peak hours. Portions of TH 5 are overloaded for up to 8 hours per day. In 2015, TH 5 carried 39,000 vehicles per day at Chanhassen's eastern border, down from the 55,000 vehicle trips per day in 2005, relief from the congestion of TH 5 was due to the construction of U.S. Highway 212 through Chanhassen. TH 5 west of TH 41 continues to be a traffic-congestion problem and with continued growth in western Carver County, congestion along this corridor is expected to increase. With U.S. Highway 212 opening in 2009, some of this congestion has decreased with 26,000 vehicle trips per day in 2015. The City of Chanhassen should continue to partner with Carver County, the City of Victoria, MNDOT and other communities along the corridor to plan for future improvements and identify funding. TH 7 TH 7 experiences congestion during peak hours of traffic. Daily traffic volumes exceed the design capacity for a two-lane highway. TH 41 Existing sight distances at various areas along the corridor are potentially inadequate.Additionally with 14,600 vehicle trips per day north of TH 5 and 13,200 vehicle trips per day south of TH 5 in 2015, the capacity of this roadway is being stressed. TH101NorthofTH5 This corridor should be widened and turn lanes installed at intersections to improve function.Also, geometric improvements should be made. Since a substantial portion of TH 101 is in Carver County, Chanhassen, Eden Prairie and Hennepin County. jurisdictional and functional continuity are significant concerns that could have major consequences for the city. TH 101 South of Pioneer Trail to CSAH 61 The highway has significant alignment and geometric problems. TH 101 from TH 5 to Pioneer Trail was improved by MnDOT, Carver County and Chanhassen and will jurisdictionally be transferred to Carver County for future maintenance. The intersection of TH 101 and Pioneer Trail(CSAH 14)has been widened and signalized (2005). The purpose of the project is to improve traffic safety, capacity and connectivity issues on TH 101 between Pioneer Trail and Flying Cloud Drive, which involves realigning and reconstructing 1.2 miles of TH 101 from a two-lane undivided roadway to a four-lane divided roadway with turn lanes at key intersections. A paved multi-use trail is proposed along both sides of TH 101 from Pioneer Trail to Creekwood Drive and along the east side only from Creekwood Drive to Flying Cloud Drive. The City of Chanhassen, in cooperation with MnDOT and Carver County, completed the preliminary design and environ- mental review(Environmental Assessment Worksheet)for Highway 101 from Pioneer Trail(CSAH 14)to Flying Cloud Drive (CSAH 61). On November 23, 2015, the City of Chanhassen officially mapped the preferred alignment. 1.

Additional funding will need to be secured for the future improvements to the corridor. It is expected that Federal, State and local funds will be needed to help finance these improvements. Pleasant View Road The existing roadway alignment is inadequate in several areas. Sharp curves, private building structures located at the right of way line, hidden driveways and frequent vistas of Lotus Lake,which serve as a distraction, all combine to create a poor functioning corridor. Due to the need for more right-of-way, previous efforts to improve Pleasant View Road have been unsuccessful. As a result, the inadequacies of this route will continue to intensify in the future as traffic volumes increase. Bluff Creek Boulevard The city constructed a portion of Bluff Creek Boulevard east from Audubon Road (CSAH 15) as part of the 2005 MUSA project. However, the final segment, approximately half a mile, of the roadway to Powers Boulevard was not included in the project. This roadway must be constructed with the development of the properties west of Powers Boulevard. Galpin Boulevard (CSAH 117) This roadway provides a connection through Chanhassen to the City of Shorewood and Hennepin County ending at TH 7. In Chanhassen, the roadway is a rural design standard and should be upgraded to an urban design with capacity im- provements. In Shorewood, the roadway narrows down and becomes a substandard road system. Sunset Trail, North Collector Street Connection ; Local collector roadways were identified in the 2005 MUSA project to properly service the development of this area and d connect to the County roadway system. This collector road will connect to Lyman Boulevard (CSAH 18). The connection a will be constructed with the development of the properties in the area. § U Eagle Ridge Road, East/West Connection E A connection from TH 101 with a touch down in the vicinity of Bandimeer Park, to Powers Boulevard(CSAH 17)with a d touch down between Highway 212 and Homestead Lane. These connections will be constructed with the development of %� the properties in the area. Lyman Boulevard(CSAH 18) o Chanhassen, Chaska and Carver County are currently working on planning for the future improvements to Lyman Boule- E3 yard from Galpin Boulevard to the west. 121 Bluff Creek Golf Course A connection from Pioneer Trail and Powers Boulevard to TH 101 will be required as part of any redevelopment of the golf Qcourse. The existing Creekwood Drive is not designed or constructed to accommodate redevelopment traffic. These c connections will be constructed with the development of the properties in the area. it Flying Cloud Boulevard(CSAH 61) A continuation of the improvement to CSAH 61 west of Bluff Creek Drive to Engler Boulevard is being reviewed by Carver County, Chanhassen and Chaska. These improvements are intended to improve traffic capacity. However, this project is part of the unfunded high priority roadway projects. Other Local Street Improvements: Dogwood Road/Crimson Bay Road At the present time, Crimson Bay Road does not connect to Dogwood Road. Correspondingly, the Crimson Bay neighbor- hood has only one means of egress/ingress. A future street connection in this area is needed to alleviate existing access problems. Additionally, it is anticipated that once this connection is made, access to TH 5 shall be made into a right-in/ right-out only. Fox Hollow Drive The right-of-way is dedicated for the roadway connection. However, the public street does not connect to the two ends of the road. Currently, through traffic must go through a driveway on the North Lotus Lake Park property to continue on Fox Hollow Drive. A public street should be constructed within the right-of-way to complete this roadway as part of any street maintenance or reconstruction project. Nez Perce/Pleasant View Road Connection During review of the Vineland Forest plat, it was evident that a connection between Nez Perce/Lake Lucy Road and Pleasant View Road was warranted since there was no north-south connection between Powers Boulevard (CSAH 17)and Lotus Lake. Improved access is needed for local trips and to ensure the adequate provision of emergency services. At the same time, there were concerns voiced regarding the introduction of additional trips onto Pleasant View Road since the street already suffers from capacity and design constraints. Therefore, it was determined that the Pleasant View Road intersection should be located as far west as possible at the Peaceful Lane intersection. Pipewood Lane and W.62nd Street A secondary access to this area was discussed as part of the plat for Hidden Creek Meadows. Cathcart Lane is a sub- standard gravel roadway that provides emergency access to the area. With the future development of the farmstead, a public street will connect these roadways. Timberwood Drive/Stone Creek Court The neighborhoods of Timberwood Estates and Stone Creek are separated by approximately 30 feet of unfinished road. This connection would permit the residents of Timberwood Estates to access the Bluff Creek trail system. In addition, this connection could provide a secondary access to Timberwood Estates for residents and emergency vehicles. d E 0 U N C N U 0 U 122 6.4 Future Traffic Forecasts The city has relied on the 2040 baseline traffic forecasts incorporated within the Carver County Transportation Plan to c determine the adequacy and appropriateness of the street and highway system to accommodate the development that N is expected to be in place by the year 2040. The forecasts were prepared based upon projected population, households i and employment data developed by the City of Chanhassen and Carver County in conjunction with the Metropolitan Council. 2040 Baseline—Development assumptions are consistent with the Metropolitan Council's Thrive MSP 2040. The population, household, and employment information was distributed throughout the city to a refined network of Traffic Assignment Zones(TAZ). The analysis assumed improvements to regional facilities only if they were programmed. Other local improvements were assumed if they have been included in previous transportation plans and were part of the arteri- al system. These system improvements are listed as follows: TH 41: Four lanes from Highway 5 to the south Carver County boundary. TH 101: Four lanes from Pioneer Trail (CSAH 14)to Flying Cloud Drive(CSAH 61) Lyman Blvd: Four lanes from Galpin Boulevard (CSAH 15)to TH 41. The resulting traffic projections are shown in the 2040 Average Daily Traffic (ADT)map. The forecasts are based on a capacity restrained network. The level of congestion of the future highway system depends in large measure on both the capacity improvements un- dertaken and the availability of a local arterial system to complement and relieve the regional system. The 2040 forecasts suggest the following: Regional facilities (TH 7, TH 5,TH 41 and U.S. Highway 212)currently are congested. With little or no capacity improvements to these facilities, congestion will increase on these facilities. In addition, more trips will divert to local routes such as CSAH 14(Pioneer Trail), CSAH 18(Lyman Boulevard), County Road 117 (Galpin), CSAH 17 (Powers Boulevard)and to other collector routes within the city. Regional river crossing bridges(TH 41 and TH 101)are congested currently and will become more congested as the region expands. The development of U.S. Highway 212 is anticipated to attract more trips from Scott County and U.S. Highway 169.A connection from Highways 212 to 169 will provide relief to this congestion. Agencies should continue to investigate and preserve this corridor or identify how existing corridors could be expanded to address river crossing needs. While CSAH 101 was raised above the flood elevation and widened to four lanes in 2016, additional cross river traffic is anticipated. Improvements proposed for municipal roadways are under direct control of the city and will receive highest priority in the city's Transportation Improvement Program. For roadways on the county system,the city will cooperate with Carver Coun- ty and encourage the improvement of county roads in accordance with this plan. 6.5 I System Plan The proposed roadway system should be consistent with the anticipated density and distribution of land uses in the city in the year 2040. The purpose of this section is to review the existing functional classification system and identify potential p functional classification and other system changes that should be made to accommodate the anticipated growth. Guiding Planning Principles The City of Chanhassen Transportation Plan has been developed using the following guidelines and planning principles: 1. The functional classification of the roadway system in Chanhassen should conform to the following criteria and characteristics: The trip length characteristics of the route as indicated by length of route, type and size of traffic generators served, and route continuity. U 123 The ability of the route to serve regional population centers, regional activity centers and major traffic generators. a » The spacing of the route to serve different functions(need to provide access and mobility functions for entire area). ea The ability of the route to provide continuity through individual travelsheds and between travelsheds, » The role of the route in providing mobility or land access(number of accesses, access spacing, speed, parking and traffic control). » The relationship of the route to adjacent land uses(location of growth areas, industrial areas and neighborhoods). » The spacing guidelines for the specific road classification. The functional classification system is broken down into four categories—principal arterials, minor arterials(`A' and `B'), collectors (major and minor)and local roadways. 2. The plan should reflect vehicular travel demand at full development. 3. The full development level, as defined by the proposed Land Use Guide Plan, should incorporate the limiting effects that the identified physical constraints have on the attainment of the anticipated level of development. 4. Compatibility and connectivity should be maintained between the roadway system in Chanhassen and county and regional roadway systems. 5. In developing the plan, roadway segments and intersections that cannot accommodate the anticipated vehicular travel demand should be identified. Functional Classification System The functional classification criteria were closely followed during the preparation of this plan. The intent of a functional classification system is the creation of a hierarchy of roads that collects and distributes traffic from neighborhoods to the metropolitan highway system in the most efficient manner possible given the topography and other physical constraints of the area. Places of high demand, employment or commercial centers, should be served by roadways higher in the hierar- chy such as arterial roads. Neighborhoods and places of low demand should have roadways of lower classification such as collectors and local streets. It is in this way that the land use plan is integrated into the transportation plan. An important consideration in developing a functional classification system is adherence to the spacing criteria estab- lished by the Metropolitan Council (Table 6.4). The City of Chanhassen is currently considered part of the emerging sub- urban edge area. As a result,the city has a mixture of urban, suburban, and rural areas. It is anticipated, however, that the city will be fully developed by 2040. The ultimate roadway system assumes full development, but the current distinc- tion between developing and rural is important in the establishment of implementation priorities.

The classification system is consistent with the preliminary changes that are being proposed by Carver County in the update of their transportation plan. Since the plan is still under development, there may be some further modification of the functional classification system. a a The functional classification plan includes the following categories: C 1.

These roads are intended to connect the central business districts of the two central cities with each other and with other 6 regional business concentrations in the metropolitan area. These roads also connect the Twin Cities with important loca- tions outside the metropolitan area. r= Principal arterials are generally constructed as limited access freeways in the developed area, but may also be constructed as multiple lane divided highways.The following facilities are designated as principal arterials within the City of Chanhassen: Trunk Highway 7 TH 7 serves as a key east-west route through the south central portion of Minnesota. It connects the Twin Cities Metropolitan Area with cities such as Hutchinson, and Montivideo to the west. It is located in the northern portion of Chanhassen and pro- vides regional access and mobility to primarily residential areas. In Chanhassen, vehicle movements are generally uninhibited by signals or major street intersections.To the east, however, Highway 7 passes through Minnetonka and northern Hopkins where there are more frequent signalized intersections and commercial development.The roadway carries substantial vehicu- lar traffic and is considered congested(LOS F)during peak travel periods. East of TH 41,TH 7 is a four lane divided highway. West of TH 41, it is a two lane highway. Eventually,TH 7 should be upgraded to four lanes. U.S. Highway 212 The U.S. Highway 212 is a principal arterial and connects small rural communities to the Twin Cities Metropolitan area. In Chanhassen, U.S. Highway 212 travels diagonally across the southern third of the city.This facility was planned for many years and became operational in 2007. The route is a four lane divided facility with controlled access at two interchanges in Chanhassen, one at TH 101 and the other at CSAH 17. New Principal Arterial River Crossing Currently there is a lack of a principal north-south arterial route in the region.This is due to physical constraints such as Lake Minnetonka and Minnesota River bluff area as well as past travel patterns favoring east-west travel. However,as the urban area continues to grow,north-south travel demand is anticipated to increase.The spacing from the Bloomington Ferry Bridge (U.S. Highway 169)to TH 101 is approximately 7 miles.This is inconsistent with the functional classification guidelines. A north-south regional river crossing has been shown previously on the Metropolitan Council's functional classification system. This route is intended to accommodate regional trips between new Highways 212 and 169. This route was designated a principal arterial route in lieu of designating the current alignment of TH 41 a principal arterial route.This was primarily done because TH 41 goes through downtown Chaska and has numerous access points and limited ability for capacity improvements.The existing river crossings on TH 41, CSAH 101 and U.S. Highway 169 are shown to be at capacity based on traffic forecasting work done for the Carver County Transportation Plan.Therefore, expansion of existing river crossings or an additional regional river crossing appears to be needed to address regional growth. As part of the review process for the river crossing, MnDOT had prepared a Tier I Draft Environmental Impact Statement (DEIS),TH 41 Minnesota River Crossing. The study process began in 2002.The scoping decisions for the environmental reviews were made in February 2005 and revised in February 2006. The DEIS review and comment period ended on August 10, 2007. The end result of the DEIS is to identify a preferred alignment for the new river crossing.The preferred alignment a should be both a cost effective solution and minimize social,economic and environmental impacts.Once the preferred r alignment is chosen, local governments will need to officially map the alignment in order to preserve it for the river crossing. The preferred alignment begins near the boundary of Carver and Chaska, goes south of the Chaska Athletic Fields and then parallels TH 41 across the Minnesota River to U.S. Highway 169. A Tier I Environmental Impact Statement review was completed for the river crossing in 2015.This study was done so that a corridor could be selected for preservation for the future Minnesota River Crossing.The crossing will connect Highways 169 --sk and 212, near Highway 41. MnDOT worked with the Federal Highway Administration(FHWA), local governmental units,the Metropolitan Council, state and federal resource agencies and other interested parties to study the need for and potential impacts of this project.A Record of Decision was signed by the FHWA on March 16, 2015. 127 Design details will be studied during a Tier II Environmental Impact Statement process that will occur closer to construction, which is not anticipated for several years. It is anticipated that this route will be a four lane divided highway with interchange c access only. CL Minor Arterials co � Minor arterials are designed to emphasize mobility over land access, serving to connect cities with adjacent communi- ties and the metropolitan highway system. Major business concentrations and other important traffic generators are often located on minor arterials. In the metropolitan area, minor arterials are divided into two classes "A" Minor Arterials and "B" Minor Arterials. The number of lanes on arterial routes should be based on the projected volumes routes are likely to be constructed either as four-lane undivided roads or as three-lane roadways where there is insufficient right-of-way when the system is complete. 1. "A" Minor Arterials The Metropolitan Council has identified minor arterials that are of regional importance because they relieve, expand, or complement the principal arterial system. These roads have been labeled "A" minor arterials and have been categorized into four types: Relievers-Minor arterials that provide direct relief for metropolitan highway traffic. Expanders-Routes that provide a way to make connections between developing areas outside the 1-494, 1-694 interstate ring. Connectors-Roads that would provide good, safe connections to and among town centers in the transitional and rural areas in the area. Augmenters-Roadways that augment principal arterials within the interstate ring or beltway. To the extent possible, "A" minor arterials are the most continuous and form a grid network over the entire city; however, topographic constraints and the location of existing highways and existing land uses can result in deviations from the spacing guidelines. Nevertheless, continuity and connectivity among the "A" minor arterials and the principal arterials allows the arterial network to provide important mobility functions throughout the city. In Chanhassen,the current spacing of"A" Minor arterials is approximately every one mile(spacing between TH 101, CSAH 17 and TH 41). The desirable spacing for"A"minor arterials is considered to be one half to 1 mile for fully developed areas. Be- cause Chanhassen is anticipated to be fully developed by the year 2030, additional"A" minor arterials should be designated to maintain mobility throughout the city. The "A" Minor Arterials that are recommended in Chanhassen include the following: Trunk Highway 5 Trunk Highway 5 is important roadway in Chanhassen functioning as the city's transportation backbone. In the early 1970's, TH 5 was considered a principal arterial route. This designation has changed over time because of the close proximity of TH 7 and lack of continuity west of Carver County. Currently,TH 5 serves as the major link for Chanhassen to the metropolitan area. In addition, TH 5 provides regional access to a large number of businesses and industrial properties in the area. The concentration of these large employers results in some"reverse commuting" patterns as well as destinations for many trips coming in to Chanhassen from the west. Even though this route is designated as a minor arterial, it provides many functions similar to TH 7 and U.S. Highway 212 which are principal arterial routes. As a result, it is recommended that the city continue to support improvement and access management strategies that would maintain the mobility of this route. t Within Chanhassen,the flow of traffic along Highway 5 is interrupted by traffic signals at TH 41, Century Boulevard, CSAH 19 (Galpin Boulevard),Audubon Road,CSAH 17(Powers Boulevard), CSAH 101 (Market Boulevard), Great Plains Boulevard, Dakota Avenue, and Dell Road. There are no significant commercial or residential uses accessing directly onto Highway 5. Eastbound traffic on TH 5 typically connects with either 1-494, U.S. Highway 169 and TH 62. From the Chanhassen border to 1-494, TH 5 contains signalized intersections at Eden Prairie Road and Fuller Street. These signalized intersections combined with higher traffic volumes in Eden Prairie contribute to significant traffic delays during peak hours. TH5 is a 0 four lane highway east of TH 41 and two lane west of TH 41. Eventually,TH 5 should be a four lane facility. 0 U 128 Trunk Highway 41 -Hazeltine Boulevard Another"A" minor arterial that has many principal arterial characteristics is TH 41. This route is located in western Chanhas- sen and is a major north-south river crossing west of the Bloomington Ferry Bridge(nine miles to the east)that connects U.S. Q Highway 169, U.S. Highway 212,TH 5 and TH 7. As a result,this route will continue to be an important link serving Carver County and the City of Chanhassen.Chanhassen and Chaska have done a good job in protecting the mobility of this corridor 12 by providing limited access and proper development setbacks. With other north-south corridors being limited,the volumes on this corridor are anticipated to increase as additional development occurs. Currently,TH 41 is a two lane highway through Chanhassen. Eventually, it should be a four lane facility. TH 101/CSAH 101 This designation is consistent with the Metropolitan Council's Functional Classification Plan and Hennepin County's designa- tion. This designation is consistent with the spacing guidelines for developing areas. The projected year 2030 daily volumes are at the upper limit or exceed the recommended guidelines for volumes. The roadway connects principal and other minor arterial routes thereby providing an important mobility function for the region. The city has historically limited direct access to Highway 101 and will continue to do so. North of TH 5,TH 101 is a two lane facility. South of TH 5 to CSAH 14(Pioneer Trail), CSAH 101 is a four lane facility. CSAH 61 -Flying Cloud Drive After the construction of new U.S. Highway 212, old TH 212(CSAH 61)was downgraded from a principal arterial route to an "A" minor arterial. Flying Cloud Drive is a two lane undivided highway with limited access control on the segment within Chanhassen; however,the river bluff substantially restricts the ability to access this route. The route continues to link Chaska and CSAH 101 river crossing with Twin Cities Metropolitan Area. The route fits the spacing guidelines for"A" minor arterial routes and provides east-west traffic flow below the bluff. In conjunction with the construction of the CSAH 101 river crossing, Carver County reconstructed CSAH 61 from Highway 101 to Bluff Creek Drive. A continuation of the improvements to CSAH 61 west of Bluff Creek Drive to Engler Boulevard is being reviewed by Carver County, Chanhassen and Chaska. However,this project is part of the county's unfunded high priority roadway projects. Reconstruct Flying Cloud Drive(CSAH 61)from Highway 101 in Chanhassen to Charlson Road in Eden Prairie(3.7 Miles)is programmed to begin in 2017. Hennepin County is leading this reconstruction project.The reconstruction includes: » Two-lane roadway with shoulders » Continuous Shared Center left-turn lane » Right-turn lanes at key intersections » Multi-use trail on north side of roadway » Raise road out of 100 year flood plain » Retaining Walls » Bridges » Intersection Improvements CSAH 14-Pioneer Trail County State Aid Highway 14 is currently classified as an "A" minor arterial based on the spacing with other similar east west routes and the connections that it provides to other arterial facilities: CSAH 15, CSAH 17 and CSAH/TH 101. U CSAH 15-Audubon Road(Lyman Boulevard to south boundary)and Galpin Boulevard(TH 5 to Lyman Boulevard) Together these routes form a north-south connection between CSAH 61 and TH 5.This route meets the spacing with other similar north-south routes and the connections that it provides to other arterial facilities. It connects facilities such as CSAH - 61,CSAH 14(Pioneer Trail), CSAH 18(Lyman Boulevard)and TH 5. North of CSAH 18(Lyman Boulevard)the spacing of this u roadway with CSAH 17 to the east is approximately one mile and the spacing of this route with TH 41 to the west is approxi- mately one mile. However,there are physical barriers(Bluff Creek)that limit the connections between these routes. 129 o North of CSAH 18(Lyman Boulevard)the spacing of this roadway with CSAH 17 to the east is approximately one mile and the • spacing of this route with TH 41 to the west is approximately one mile. However,there are physical barriers(Bluff Creek)that -6 limit the connections between these routes. North of CSAH 18(Lyman Boulevard)the spacing of this route with TH 41 to the cwest is approximately two miles and the spacing of this roadway with Powers Boulevard to the east is approximately one and a, one-half miles. As the City of Chanhassen develops,this facility will provide mobility for north-south traffic flow to important destinations within the city as well as the regional transportation system CSAH 17- Powers Boulevard County State Aid Highway 17 is classified as an "A" minor arterial based on the spacing with other similar north-south routes and the connections that it provides to other arterial facilities. It connects facilities such as CSAH 14(Pioneer Trail), U.S. Highway 212(interchange), TH 5, and TH 7. The spacing of this roadway with TH 101 to the east is approximately one mile; however, there are physical barriers(lakes and wetlands)that limit the connections between these routes. The spacing of this route with TH 41 to the west is approximately two miles. As the City of Chanhassen develops, this facility will provide mobility for north-south traffic flow to important destinations within the city as well as the regional transporta- tion system. It is recognized that the character of CSAH 17 does change as it extends north into Hennepin County(CSAH 82).The roadway becomes narrower and setbacks are limited. 2."B" Minor Arterials The Metropolitan Council defines all minor arterials other than "A" minor arterials as "B" minor arterials. These roadways also serve a citywide function. Medium to long distance trips use the "B" minor arterial system. When combined with the "A" minor arterial system, most places in the city are within a mile of such a roadway. There is one route in the City of Chanhassen that is proposed as "B" minor arterial. This route is described as follows: CSAH 18-Lyman Boulevard Lyman Boulevard is designated as a "B" minor arterial. It is an east-west route that parallels TH 5 one to one and one-half �-' miles to the south. It currently connects TH 41, CSAH 17 and TH 101; however an extension is planned to the west of TH 41. The spacing guidelines are consistent with designation of an "A" minor arterial for this route. However, we have cho- sen to leave the designation of Lyman Boulevard as a "B" minor arterial because it lacks of continuity east of TH 101. It is in close proximity to the arboretum and there are limited setbacks in the City of Victoria. Major Collectors Major collectors are designed to serve shorter trips that occur entirely within the city and to provide access from neighbor- hoods to the arterial system. These roads supplement the arterial system in the sense that they emphasize mobility over land access, but they are expected, because of their locations, to carry less traffic than arterial roads. The following roadways are recommended as Major Collectors in Chanhassen. Minnewashta Parkway. This street serves as the only north/south route between TH 5 and TH 7,west of Lake Minnewashta. It is also located such that it likely serves some through trips from outside the city along TH 5,traveling to the north to TH 7, as well as locally generated traffic along its route. » Galpin Boulevard (CSAH 117)north of TH 5-This route connects TH 5 to Shorewood and Highway 7 and is approximately midway between TH 41 and CSAH 17. oLake Drive-Lake Drive serves two functions: local access south of TH 5 and a parallel collector to TH 5. This route is V capable of carrying off loaded local trips of short to medium length. The city undertook a joint project with MnDOT and the City of Eden Prairie to extend Lake Drive East to the city line where it merges with the signalized intersection at TH 5 and Dell Road. Pleasant View Road-Pleasant View Road serves as the only east-west connection between CSAH 17 and TH 101 in northern Chanhassen. Lake Lucy Road-Lake Lucy Road serves as the only east-west connection between TH 41 and CSAH 17 in northern Chanhassen. 130 • Coulter Boulevard-Coulter Boulevard serves two functions.These include local access south of TH 5 and a parallel collector to TH 5 capable of carrying off loaded local trips of short to medium length. • West 78th Street-This east-west route connects TH 41 to TH 101. It parallels TH 5 and provides local access to the a properties adjacent to TH 5. Minor Collectors » Great Plains Boulevard-This route connects West 78th Street to Lake Drive East. Kerber Boulevard-This route connects West 78th Street in downtown Chanhassen to Powers Blvd. and is parallel to Powers Blvd. Market Boulevard-This route provides a link between TH 5 and downtown Chanhassen. Century Boulevard-This route provides a north south link between West 78th Street,TH 5 and 82nd Street West. » Bluff Creek Drive-This route provides a north-south connection from Bluff Creek Boulevard to Flying Cloud Drive. Bluff Creek Boulevard-This route provides an east-west connection from CSAH 15 to CSAH 17 and U. S. Highway 212 interchange. The eastern portion of this roadway will be constructed with the development of the adjacent property. • Dakota Avenue(TH 5 to Lake Drive East). This route completes the connection of TH 101 Yosemite-Lake Lucy Road to city boundary provides a valuable link between Chanhassen and Excelsior. (This route has been added to the collector system since the 2030 Comprehensive Plan.) The ultimate roadway system is based upon the functional classification presented above. It reflects full development of the city according to the land use plan and socioeconomic forecasts presented earlier. The roadway cross-section identi- fied for each classification would be expected to be in place at the time full development is achieved. --� 6.6 Planned and Programmed Improvements Roadway Plan Traffic on Chanhassen's roadway system will continue to increase due to new commercial, residential and industrial development and changes in socio-economic conditions. The impact of added traffic will be more evident on primarily the arterial and collector routes. However,failure to address capacity issues on major routes will result in more traffic diverting to local streets. This can result in safety, speed and other undesirable impacts to collector routes. In order to ensure that traffic concerns are addressed thoroughly and comprehensively,the transportation chapter of the Chanhassen Comprehensive Plan contains a planned and recommended roadway system for the year 2040. This system is the result of both current and past planning efforts. The following major improvements are components of the recommended and planned transportation system: TH 5 The city will continue to work to get TH 5 improved west of TH 41. The current Carver County Transportation Plan indicates a need for a four-lane TH 5 west toward Waconia to accommodate traffic flows. TH 101 Planning efforts since 1980 have consistently identified the need for improvements to TH 101. Planned improvements north of TH 5 consist primarily of reconstruction and realignment of the route north of the intersection of TH101 and West 78th Street to effectuate better traffic flow. Based on traffic projects,a four-lane roadway may be required. CSAH 101 Has been widened to 4-lanes and the alignment improved from TH 5 to Pioneer Trail(CSAH 14) E3 131 c On January 9, 2006,the city approved a Joint Powers Agreement with Carver County and the Minnesota department of Trans- '? portation to fund the corridor study from Lyman Boulevard(CSAH 18)to Scott County. The purpose of this study was to iden- tify deficiencies and improvements necessary for a two-lane, 3.3 mile segment of TH 101 Corridor in Chanhassen between cLyman Boulevard(CSAH 18)on the north and the Scott County Line on the south. The city proposed that construction of co this project be split in to at least two phases. Phase I would be from Lyman Boulevard(CSAH 18)to Pioneer Trail(CSAH 14), which has been completed. Improvements south of Pioneer Trail(CSAH 14)depend on MnDOT turn-back program funding or other funding sources. The road includes a four-lane design. The CSAH 101 river crossing completed in 2016 expanded the bridge to four-lanes to accommodate traffic with a pedestrian trail on one side. TH 41 TH 41 needs to be upgraded to a four-lane cross section from TH 7 south to the County line. In addition, the vertical align- ment of the south approach to TH 5 must be reduced to improve the safety of this heavily used intersection. New Regional River Crossing U.S. Highway 212 to U. S. Highway 169 Currently, TH 41 and TH 101 bridges serve the river crossing needs for the region. TH 41 is significantly over capacity. The expansion of CSAH 101 river crossing has improved traffic crossing the river. The city will work with adjacent commu- nities, Mn/DOT, and the Metropolitan Council to determine potential alternatives to address capacity needs in the region. The regional river crossing will be a four-lane facility with limited interchange access. It is not currently in any funding plan. CSAH 18(Lyman Boulevard). Chanhassen, Chaska and Carver County are currently working for the future improvement to Lyman Boulevard west of Galpin Boulevard. This roadway will require a four-lane design. �- CSAH 14(Pioneer Trail) This road way provides a vital transportation connection from Hennepin County to western Carver County. Based on pro- jected traffic volumes, a four-lane roadway design is required. Recommended Local Street Improvements As Chanhassen continues to develop,transportation conflicts and inconsistencies will become evident. These situations, unlike planning for major routes, are not predictable since they result from the merging of existing and new land use patterns. The Comprehensive Plan can be a useful tool in assisting the city in resolving these local access situations. It is the city's policy to require interconnections between neighborhoods to foster a sense of community,to improve safety and to provide convenient access for residents. Often during the subdivision review process,the need for future extension of local streets becomes apparent. As a result, access concepts are developed to assist in creating an acceptable configuration for the plat and as a guide for the future development of adjoining parcels. It is the city's intent that the Comprehensive Plan serve as an implementation tool by providing a means by which to record these access plans, legitimizing them by the nature of the fact that they are approved by the City Council prior to recording. It also will provide a useful means of providing information to residents and developers t seeking information of future development potential. These concept plans are illustrated below. Additional concept plans will 1. be added to this document over time as they are developed. E $ Bluff Creek Boulevard The final connection from Powers Boulevard to the westerly terminus of the roadway will be constructed with the development of the underlying properties. North and South 2005 MUSA Collectors o The connection from Bluff Creek Boulevard to Lyman Boulevard will be constructed in conjunction with the development of the underlying properties.The south connection was constructed in conjunction with the Pioneer Pass development(Bluff Creek Drive). 132 Eagle Ridge Drive east-west connection c This roadway will connect CSAH 17 to CSAH 101. The first section of this roadway was installed in the Foxwood development. "--"N The remainder of the connections will be constructed with the development of the properties in the area. It should be noted that this connection will likely provide additional connections to West 96th Street and Homestead Lane I Dogwood Road/Crimson Bay Road Crimson Bay Road does not connect to Dogwood Road. Correspondingly,the Crimson Bay neighborhood has only one means of egress/ingress.A future street connection in this area is needed to alleviate existing access problems. Carver Beach Road Conditions Chanhassen's Carver Beach neighborhood was one of the first residential developments on Lotus Lake. This area consists of smaller lots and narrow rights of way. Drainage problems occur due to topography and a lack of storm sewer facilities in some portions of the area. Improvement of existing conditions can only occur in a comprehensive manner involving the recon- struction of both streets and utility systems. Because of development constraints,typical street standards will not be applica- ble in this area. Nez Perce/Pleasant View Road Connection During review of the Vineland Forest plat, it was evident that a connection between Nez Perce/Lake Lucy Road and Pleasant View Road was warranted since there was no north/south connection between County Road 17 and Lotus Lake. Improved access is needed for local trips and to ensure the adequate provision of emergency services. At the same time,there were concerns voiced regarding the introduction of additional trips onto Pleasant View Road since the street already suffers from capacity and design constraints. Therefore, it was determined that the Pleasant View Road intersection should be located as far west as possible at the Peaceful Lane intersection. Timberwood Drive/Stone Creek Court The neighborhoods of Timberwood Estates and Stone Creek are separated by approximately 30 feet of unfinished roads. This connection would permit the residents of Timberwood Estates to access the Bluff Creek trail system. In addition,this connec- tion could provide a secondary access for Timberwood Estates for residents and emergency vehicles. It would also facilitate improved school bus access to the neighborhood. Pipewood Lane and West 62nd Street A secondary access to this area was discussed as part of the plat for Hidden Creek Meadows. Cathcart Lane is a substan- dard gravel roadway that provides emergency access to the area. With the future development of the farmstead,a public street will connect these roadways. 6.7 Alternative Modes Transit Although private cars are the most commonly used mode of transportation for Chanhassen residents, mass transit serves as z an important alternative to automobile uses and serves as one leg of a multi-modal transportation strategy for the community. The City of Chanhassen lies within the Metropolitan Council's Transit Market Area III,which represents areas with generally I lower concentrations of activity, housing and jobs,with intermittent pockets of moderate concentrations. Metropolitan Council 8 service options for this area include peak-only express, small vehicle dial-a-ride, mid-day circulators, special needs Para-tran- sit(ADA, seniors)and ride-sharing services which are, generally,tied to park-and-ride lots and hubs.Two forms of mass tran- sit, buses and light rail/commuter rail, are specific components of this plan. Plans for these services are outlined as follows: 0 0 U 133 0 Buses In late 1986, Chanhassen joined the cities of Eden Prairie and Chaska in the creation of the Southwest Metro Transit Commis- = sion,operated under a joint powers agreement between the communities,to provide transit service known as the Southwest a Transit(SWT). The joint powers agreement is renewable on an annual basis. SWT is governed by a seven person Commis- sion. Each of the three cities has an appointed member as well as an elected official. The seventh member is a represen- tative of the riding public. The city will continue to monitor the effectiveness of the Southwest Transit program in providing cost effective transit service to the City of Chanhassen. Public transit service is provided for Chaska, Chanhassen and Eden Prairie, as well as Carver. SWT currently offers service to and from Downtown Minneapolis,the University of Minnesota, Nor- mandale Community College and Best Buy Headquarters. Park and Ride SWT has two park and ride parking ramps within Chanhassen. These ramps are located in the downtown area off Great Plains Boulevard and Market Street(Chanhassen Transit Station)and at U.S. Highway 212 and CSAH 101 (Southwest Village). In addition, SWT has parking facilities in Eden Prairie at U.S. Highway 212 and Prairie Center Drive(Southwest Station), U.S. Highway 169 and Anderson Lakes Parkway, in Chaska at U.S. Highway 212 and TH 41(East Creek Station), CSAH 61 add Walnut Street(Walnut Park&Ride), and in Carver at Jonathan Carver Parkway and Ironwood Drive(Carver Station). There are several services provided by Southwest Transit: Express Service This service provides express service for passengers working in downtown Minneapolis. Riders are picked up at any of the park and ride lots servicing Chanhassen and driven to downtown Minneapolis and the university of Minnesota without stop- ping. At the end of the workday,the service is reversed taking passengers back to Chanhassen. Reverse Commute These routes start in Minneapolis and bring passengers to job sites in Chanhassen, Chaska and Eden Prairie. Starting with only five passengers in 1992,the program has grown to serve approximately 400-450 passengers and 45-50 employers. The city's rapid growth as an employment concentration warrants service to facilitate work trips. Regional Routes SWT has 80 buses and offers service to Downtown and Uptown Minneapolis,the University of Minnesota, Fairview Southdale Hospital, the Mall of America,the Minneapolis-St. Paul International Airport,Southdale Shopping Mall and regional employ- ment centers. Special seasonal routes are also provided to the Minnesota State Fair, US Bank Stadium, and Target Field. SW Prime An on demand ride service to help transit users bridge the gap between transit stations and final destinations. This ser- vice typically has between 225 and 250 daily users. SW Prime is a transit service for Eden Prairie, Chaska, Chanhassen, Carver, and select areas in Shakopee.To transfer between zones, riders are dropped off and picked up at SW Chanhas- sen Village station on Hwy. 212 and Hwy. 101. As a modern local service, riders may request a ride through smartphone app, website, or phone, indicate the location from which they want to be picked up and where they want to go. SWT vehicles are ADA compliant. S Metro Mobility is a shared public transportation service for certified riders,who are unable to use regular fixed-route buses due to a disability N C or health condition. Rides are provided for any purpose. SmartLink Transit `5 (formerly known as Carver County Transit), provides transit dependent residents of Carver and Scott counties. It includes UDial-A-Ride, Medical Assistance and Volunteer Drivers for both Scott and Carver counties. Priority will be given to elderly, disabled, and economically disadvantaged residents. 134 WeCAB = (Community Area Busing) provides safe, affordable, and flexible supplemental transportation to those who are unable to drive to medical appointments, grocery store or food shelf, church,volunteering or social events. oa fn Other Services c a) Because the agencies mission is to meet the transit needs of the community, Southwest Transit provides a variety of otherit transit opportunities. For example, group rides are available for a variety of businesses, schools,organizations and others. Whenever possible, Southwest Transit provides buses for little or no charge for community purposes in Chanhassen and other service communities. SW Transit has also begun(2017)a seasonal and daily bike rental opportunity(SW Rides)from several of its transit stations. This program is run from April through October. Light Rail Transit(LRT)/Commuter Rail Light Rail Transit Light rail transit is a mode of transportation that is being constructed in the Twin Cities Metropolitan Area. In 1987, Hennepin County received authorization from the State Legislature to prepare a Comprehensive LRT System Plan for Hennepin County. Toward that end,the county established the Hennepin County Regional Railroad Authority to administer the system. Hennepin County owns railroad right of way from downtown Minneapolis to Victoria and Chaska. Other counties in the metropolitan area have followed Hennepin County's lead and have also established railroad authorities. There are multiple agencies involved in planning and implementing transitways in the Twin Cities region.Local governments, particularly counties and regional railroad authorities, play a lead role in the planning of transitway corridors and recommend- ing locally preferred alternatives.The Minnesota Department of Transportation(MnDOT), Metropolitan Council and Metro Transit,Counties Transit Improvement Board(CTIB), counties and cities are involved in the funding, design, and construction of transitway facilities and services. Currently,the Blue Line connecting downtown Minneapolis to Bloomington and the Mall of America and the Green Line Con- necting the downtowns of Minneapolis and St. Paul are in operation.

Eleven new stations will be built, in addition to Target Field Station.The total project cost is estimated at$1.536 billion,funded by a combination of federal, state and local sources.Construction is anticipated to begin in 2018. Commuter Rail Commuter rail is a passenger train service that connects an urban region together over moderate distances; which typically operates on existing freight tracks;and whose primary clientele travels between home and work.These trip-to-work services usually offer concentrated frequencies primarily during rush hour,with suburban station spacing typically every five miles. Commuter rail typically serves longer trips than most light and heavy rail transit lines. Commuter rail trains are normally made up of a locomotive and several passenger coaches.Commuter rail vehicles have an on-board operator,who adjusts vehicle speed in response to traffic conditions and railway signaling requirements. `— The Northstar rail line from Big Lake to Minneapolis with stops in Elk River, Ramsey,Anoka, Coon Rapids, and Fridley is the first example of commuter rail in Minnesota. The Northstar Commuter Rail line opened in 2009.The Northstar Expansion proposes to extend service to St. Cloud. Regular weekday service is designed for commuters and is available during the morning and afternoon peak-travel periods. The morning commute period features five inbound trains and one outbound train;the late-afternoon and early-evening com- mute features five outbound trains and one inbound train.There are three roundtrips each weekend day,with special event service available throughout the year. Metro Transit schedules additional trips to provide Northstar service to all Minnesota Twins and Minnesota Vikings games and other large downtown events. The city supports the continuing investigation of commuter rail as a transportation alternative for the community,the region, and the state. The Twin Cities&Western Line,which runs through the heart of Chanhassen, is a possible route. The city has advised the Metropolitan Council that any commuter rail station located within Chanhassen would need to be located between Market Boulevard and Great Plains Boulevard in downtown Chanhassen. The downtown location meets the standards of the transit-oriented development(TOD). The core area of the TOD is a relatively dense mixed-use development and constitutes from one-tenth to one-half the total TOD area. The main characteristics include: » Residential (20 to 30 percent of the TOD area), N Employment uses(20 to 30 percent of the TOD area), and Civic uses(about 10 percent of the TOD area). In 1997, the Minnesota Legislature instructed the Minnesota Department of Transportation(MnDOT)to conduct a feasibility ,6 study to determine if the Twin Cities Metropolitan Area could support commuter rail service. Out of 19 rail corridors studied, six proved to be feasible of supporting commuter rail. 136 Those six lines were divided into two tiers. Tier I included the Northstar Corridor between Minneapolis and St. Cloud.,the Red = Rock Corridor between Minneapolis and Hastings and the Dan Patch Corridor between Minneapolis and Lakeville. Tier II included the Bethel Corridor,the Rush Line Corridor and the Norwood-Young America Corridor. The city supports the classifi- a cation of the Norwood-Young America Corridor as a Tier I commuter rail corridor. Figure 6.10 I TRANSITWAY CORRIDORS Slaw Leaufaus • 9 r y j • Tunaroy Caddo. 7-4- - � - - *111 * LAM .w, luy 2007 a 2 In January 1999, MnDOT presented the results of the Twin Cities Metropolitan Commuter Rail Feasibility Study to the Minne- sota Legislature.After hearing those results the legislature passed M.S. 174.80 to 174.90 which gave the Commissioner of Mn- DOT the authority to plan, design,construct, and operate commuter rail in the State of Minnesota. Further,the Commissioner was charged with the responsibility of developing a commuter rail system plan that would ensure that, if built,commuter rail would be part of an integrated transportation system that would interface with all other forms of transportation including LRT, buses, park and ride, bicycles, and pedestrians. In developing the Commuter Rail System Plan, MnDOT has built on the re- sults from the Twin Cities Metropolitan Commuter Rail Feasibility Study and in particular the implementation strategy presented in the final report. Travel Demand Management Travel Demand Management(TDM)programs will also provide an opportunity to reduce travel demand on the regional highway system. The employment concentrations anticipated for the area, particularly in the office complexes, provide the city with a tremendous opportunity to implement TDM programs. As part of its standard approval process,the city will d work with new employers locating in the study area to ensure that employers will: o. E N promote carpooling byprovidinginformation on carpooling and van pooling to employees on a regular basis, P 9 � P 9 P 9 providing preferential parking and guaranteed-ride home; . encourage employees to participate in Minnesota Rideshare's ride-matching program; • Rail Corridors offer employees flexible work hours and set a goal to reduce peak hour trips by 10 percent; and . participate in a Travel Demand Management Organization specifically set up for major employers. This group will consider TDM measures that require cooperation among several employers such as, but not limited to: V 137 c Figure 6.11 I COMMUTER RAIL SYSTEM �s co - w.

This drop-off site will be consistent with applicable Americans with Disability Act requirements. The city may allow a group of employers to provide a shared drop-off site as long as the site is accessible to all participating employers. d z E It will be the goal of the city to reduce peak hour trip generation to and from the study area by 10 percent through the use of -g a combination of transit service and TDM programs. The city supports investigation of TDM strategies to reduce trip levels 0 on area roads. The city will be advocating the development of a multi-community, multi-county partnership with the business o community to promote these strategies. E " Airports 4,5 There are no existing or planned airports within the City of Chanhassen. Commercial air service is available at Twin Cities International Airport and general aviation is available at Flying Cloud Airport in Eden Prairie. Flying Cloud Airport is approxi- a mately 4 miles east of the City of Chanhassen. z. U 138 Despite the lack of airports in Chanhassen,the city has two primary aviation concerns: first-physical obstructions are con- trolled,and second -seaplane operations. At the present,the tallest man-made structures within Chanhassen are the city's water towers,which average 135 feet. Structures under 200 feet are not considered obstructions under state rules. Radio c towers are the only potential structures that may exceed the 200 foot threshold. If proposals for towers occur,the city will require that they comply with all State, Federal and local requirements. H Lakes Minnewashta and Riley are used by seaplanes. To date,there have been few conflicts between boat traffic and sea- plane usage. Continued usage in these areas is not viewed as a major issue due to the small number of aircraft and off peak hour operation by their owners. If in the future the numbers of aircraft increases or the potential for serious usage conflicts occurs,the city may work with State and regional authorities to limit or ban seaplane usage. Autonomous Vehicles An autonomous car(also known as a driverless car, auto, self-driving car, robotic car)and Unmanned Ground Vehicle is a ve- hicle that is capable of sensing its environment and navigating without human input. Many such systems are evolving, but as of 2017 no cars permitted on public roads were fully autonomous.They all require a human at the wheel who must be ready to take control at any time. Autonomous cars use a variety of techniques to detect their surroundings, such as radar,laser light, GPS,odometry,and computer vision.Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage.Autonomous cars must have control systems that are capable of analyzing sensory data to distinguish between different cars on the road. The potential benefits of autonomous cars include reduced mobility and infrastructure costs, increased safety, increased mo- bility, increased customer satisfaction and reduced crime. Specifically a significant reduction in traffic collisions;the resulting injuries; and related costs, including less need for insurance.Autonomous cars are predicted to increase traffic flow; provided enhanced mobility for children,the elderly, disabled and the poor; relieve travelers from driving and navigation chores; lower fuel consumption; significantly reduce needs for parking space; reduce crime;and facilitate business models for mobility as a service, especially via the sharing economy. Among the main obstacles to widespread adoption are technological challenges, disputes concerning liability;the time period needed to replace the existing stock of vehicles; resistance by individuals to forfeit control;consumer safety concerns; im- plementation of a workable legal framework and establishment of government regulations; risk of loss of privacy and security concerns, such as hackers or terrorism; concerns about the resulting loss of driving-related jobs in the road transport industry; and risk of increased suburbanization as travel becomes less costly and time-consuming. Many of these issues are due to the fact that autonomous objects, for the first time,allow computers to roam freely, with many related safety and security concerns. (Wikipedia September 19, 2017) As autonomous vehicle technology continues to evolve and gain acceptance and use,the city will follow and evaluate the potential of such vehicles and its implications to city regulations and design requirements. Trails and Sidewalks The sidewalk and trail system is discussed primarily as part of the recreation element in the Comprehensive Plan.The city desires to be pedestrian friendly. To accomplish this,the city must assure that city improvements and private developments I provide pedestrian and bicycle linkages. An integral component of the transportation system is the pedestrian and bicycle 0 sidewalks and trails. Trails also provide a health benefit to residents and visitors to the city. The city continues to plan for an extensive trail system throughout the community. These trails will provide linkages between individual neighborhoods as well as connecting these neighborhoods to the rest of the community. As new development is proposed and reviewed,the city will continue to require that these pedestrian linkages be included as part of the project. Total Number of Trails: 95.3 miles Total Number of Sidewalks: 32.1 miles 139 6.8 I Relationship of the Transportation Plan to Metropolitan System In 2015,the Metropolitan Council issued a Systems Information Statement to the City of Chanhassen. The city was encour- y aged to address issues identified in the Statement and to ensure that planning in Chanhassen was consistent with the Met- Lropolitan Council's newly revised Transportation Policy Plan. This section is intended to identify how the revisions to the city's Transportation Plan support the Metropolitan Council's Plan. As the region continues to grow, utilization of the metropolitan highway system is expected to increase. In some cases, these facilities will become congested. Due to the regional function that these facilities perform, many of the factors affecting seg- ments that are in the City of Chanhassen are beyond the city's control. Nevertheless,the city supports the desire to resolve transportation issues by coordinating its own efforts with those of adjacent communities, Carver County, MnDOT and the Metropolitan Council. To this effect, the city has undertaken a comprehensive approach for dealing with these transportation issues. This approach considers the following methods for dealing with current and future problems: (1)an updated roadway plan, (2)support of re- gional programs and activities; and(3)initiation of a TDM program. The city's approach to each of these is described below: 1. The city has adopted a Transportation Plan that recognizes the need to support the metropolitan highway system. The major elements of the new plan are: An arterial and collector system spaced in accordance with Metropolitan Council guidelines contained in the Transportation Policy Plan. An arterial system that provides both east-west and north-south continuity between the City of Chanhassen and adjacent communities,thus providing alternatives to the metropolitan system for medium-and long-distance inter-community trips. Arterial and collector roadways that are parallel to the metropolitan system,thus providing alternate routes for short and medium length trips and eliminate them from the metropolitan system. 2. The City of Chanhassen supports Metropolitan Council and MnDOT plans to improve the metropolitan transportation system in the following areas: The city will coordinate site-specific installations with MnDOT in order to develop geometric designs at access streets that will accommodate the resulting queues and reduce the traffic impacts on the local street system. The city supports the efforts of MnDOT to construct a new Minnesota River Crossing. 6.9 I Plan Implementation Previous sections have examined future travel demand, have suggested guidelines for developing a Transportation Plan, and have recommended a Plan that is responsive to these considerations. This section concentrates on examining the steps necessary to implement the Transportation Plan. It discusses a general strategy for moving from 2007 to the future in accom- plishing the plan. Transportation Plan Adoption • By adopting the Transportation Plan,the City Council will establish the guidelines by which decisions regarding transportation facilities will be made in Chanhassen. It should be revised as necessary to respond to changing conditions and needs. The ocity should periodically review the assumptions under which the plan was developed, including estimates of future Bevel- 0 opment, population trends, changing financial resources,energy considerations,and citizen and governmental input, and N update the plan accordingly. ▪ The plan should be circulated widely so that residents and the business community are aware of the opportunities and limita- tions that the plan provides,thus enabling all interested parties to plan with full knowledge. Jurisdictional Realignment Process In general, it is good policy that Carver County and the State(MnDOT)assume responsibility for the arterial system, and 140 that the city assume responsibility for the collector and local street systems. This is, to a large extent, the situation in Chanhassen. Currently, Carver County has not accepted the turnback of TH 101. Other roadways that are under consid- ' eration for jurisdiction change include: o. » County Road 117(Galpin Boulevard)from TH 5 to the north city limit(turnback from county to city).This roadway is = designated as a local collector street and does not function to serve regional or inter-county type traffic. However, this roadway meets a rural design standard and should be upgraded to an urban design with capacity improvements prior to the city accepting jurisdiction. » TH 5 and TH 41 —The TSP developed by MnDOT indicated that all non-principal arterial routes in the metropolitan area should be considered for turnback. This included both TH 5 and TH 41. These routes currently play a critical role in the region.A jurisdictional change should not be considered unless a new river crossing is made linking U.S. Highway 212 and U.S. Highway 169. Access Management The City of Chanhassen,through its ordinances, has authority to approve developments contiguous to city streets. As part of this process,the city will work with MnDOT and Carver County on managing access to all arterial and important collector routes within the city. Access management will help maintain mobility and provide increased safety for route users.Access guidelines will be developed as part of the Carver County Transportation Plan. The city will assist in this process by carefully considering any parcel splits along arterial corridors, promoting frontage roadways to serve developments rather than direct access. In addition, the city will make available any access guidelines to developers so that they are aware of limitations prior to beginning preliminary platting of property. Establish Improvement Programs An overall strategy of improvement,tempered by fiscal constraints, begins with an analysis of key intersection capacity —� improvement projects, safety improvements and the protection of access by establishing strict standards and by designating necessary right-of-way. Identifying future needs for facility rights-of-way followed by timely"set-aside" programs will, in the long run, save the community much in the way of financial resources. Roadway improvements should also be geared toward providing for transit needs, particularly in the area of meeting turning radii,traffic signals and adequate roadway structure. It should be pointed out that non-motorized travel needs must also be carefully considered.Chanhassen will continue its policy of designating sufficient right-of-way to provide for sidewalk and bikeway needs. 6.10 I Sources of Funding Roadways under city jurisdiction are maintained, preserved, constructed and re-constructed by the city's Department of Public Works. Rehabilitation and reconstruction pojects are typically performed by a contractor under supervision of the city's Engineering Department. Funding for these activities, including the administrative costs of operating the department, are obtained from a variety of sources including ad valorem taxes, special assessments, development fees, Municipal State Aid, state and federal project funding and tax increment financing. A major concern of the city is the availability of sufficient funds for maintenance and construction activities. If funds are unavailable, needed projects may be delayed or terminated and maintenance of existing facilities may fall short of acceptable standards. The following discussion explains the existing sources of funding and potential new sources of revenue. State Aid An extremely important source of revenue to the city is state-aid. A network of city streets called Municipal State-Aid Streets is eligible for funding assistance with revenue from the Highway User Tax Distribution Fund. This fund acts as a distribution or tax clearance fund, and tax income received into the fund is transferred to various transportation related funds for expenditure. The fund receives revenue from two principal sources: 1)gasoline taxes, and 2)vehicle registration taxes. These two sources ' are permanently dedicated to this fund. Ninety-five percent of the net proceeds of the Highway User Tax Distribution Fund are distributed annually according to a constitutionally mandated formula: 62 percent to the Trunk Highway Fund,29 percent to the County State-Aid Highway Fund, and 9 percent to the Municipal State-Aid Street Fund. 141 Assessments Property that benefits from a roadway scheduled for improvement may be assessed for a portion of the cost of construc- o tion. In order to assess a property owner, it must be demonstrated that the property will benefit from the improvement. c For this reason, it is a limited source of revenue. It is also limited by the almost certain requirement that the property must have access to the roadway. Since 1989, the city has generally been following the following assessment practices. This assessment practice is intend- ed to provide direction to city staff in preparation of assessment rolls to ensure fair and consistent treatment of all proper- ties within the City of Chanhassen. Maintenance(Pothole filling, patching, crack sealing seal coat.) Maintenance costs are not assessed to abutting property owners. Maintenance is financed through the city's Annual Budget process. Rehabilitation(Repair of problem areas to full depth, milling of edge or full width of existing pavement, repair to existing catch basins and/or curb and gutter, pavement overlay.) Rehabilitation costs are assessed using the following formula: Total Project Cost = 60% paid by city + 40%assessed to abutting (city share may be MSA, General property owners TIF, Federal or State grants, etc.) Residential properties abutting collector or commercial streets shall be assessed using the same formula; however, the assessments shall be reduced to be equivalent to a typical 31-foot residential street section. Reconstruction(Removal of existing street and construction of new street. May include sanitary sewer or water main and �.. storm water improvements. May recycle the existing asphalt as gravel base.) Reconstruction cost are assessed using the same formula as Rehabilitation. New Construction(Construction of new streets or utilities or a significant upgrade from the previous facilities, e.g., a 4-lane street replaces and existing 2-lane.) New construction will be assessed 100%to the benefiting properties. Note: If a feature(sanitary sewer, water curb and gutter, etc.)that did not previously exist is added during a rehabilitation or reconstruction project, that cost of that item is treated as new construction with the remaining project costs being treat- ed as rehabilitation or reconstruction. Work done by city crews may be maintenance, rehabilitation or new construction. This work is not typically assessed. Excep- tions would include work associated with an assessment agreement sign by the property owner and approved by City Council and work specifically authorized by the City Council to be done by city crews and assessed to the abutting properties. Ad Valorem Taxes d If 20 percent of the cost of a city project can be assessed to the adjacent property owners, the remaining cost of the proj- aect can be added to the ad valorem or property taxes of the remaining property owners in the city. Ad valorem taxes for gstreet improvements are excluded from the state mandated levy limits. E Property Tax Funding The seven metropolitan counties—through their regional railroad authorities—are authorized by State Statute to impose levies on real 74 estate of up to a maximum of 0.04835%of market valuation to pay for capital and/or operating costs of passenger rail service. Tax Increment Financing g Establishing a tax increment financing(TIE)district is a method of funding infrastructure improvements that are needed imme- diately using the additional tax revenue to be generated in future years by a specific development. Municipal bonds are 142 issued against this future revenue which is dedicated for a period of years to the repayment of the bonds or to other improve- c ments within the TIF project area. When used appropriately, a TIF can accelerate economic development in an area by insur- ing that the needed infrastructure is in place without requiring support from the usual funding. This method of financing has already been used successfully in the City of Chanhassen and is expected to be used again in selected areas in the future. a ev Potential Sources of Revenue Revenues available from current sources of funding are not always sufficient to meet highway maintenance and construction needs. In order to reduce the potential shortfall of revenue,other sources of funding need to be considered. Impact Fees Impact fees are assessed to individual developers as property is improved. An attempt is made to determine what impact the additional traffic will have on roadways both near the development and away from it. The cost associated with improving the roadway system sufficiently to handle the additional traffic is assessed to the developer. Road Access Charge Impact fees are assessed after an attempt is made to determine the specific impacts of a specific development. A road access charge would be assessed all new development based on the trip generation rate of the new development but without documenting specific impacts. Revenues from this funding source would be used to construct or improve arterial and col- lector streets in the jurisdiction collecting the tax. New legislation would be required for this type of funding mechanism to be implemented. Cities are in a position to assess these fees because of their zoning and development authority. Transportation Utility Billing Under the concept of a municipal transportation utility, all properties would be subject to a periodic fee(i.e., monthly, quarter- "1 ly), based upon the number of vehicle-trips generated by the type of property. This revenue would then be used for trans- portation improvements that produce community-wide benefits including the reconstruction of existing roads and preventive maintenance to reduce deterioration. Such a fund would be especially useful for the maintenance of collector streets which are under the city's jurisdiction, particularly when it is difficult to show enough direct benefit to adjacent property owners to be able to charge an assessment. The periodic nature of the utility billing would also provide a stable source of income to sup- port a regular maintenance program for the entire street system. Such a utility would be administered by individual cities,with each city deciding on their own fee structure. At the present time,this sort of revenue source is not permitted by the state, but efforts are underway to persuade the State Legislature to pass legislation allowing the cities to obtain revenue in this way. Wheelage Tax Any city(Minnesota Statutes Section 426.05)or metropolitan county board of commissioners(Minnesota Statutes Section 163.051) may impose an annual wheelage tax upon motor vehicles using the public streets or highways. Carver County cur- rently imposes a wheelage tax for roadway improvements in the County. Local Planning Policies Chanhassen has different policies pertaining to construction standards for urban versus rural local streets. Urban roadways are required to dedicate 60 feet of right of way for local streets and 31-foot wide pavement width. Rural roadways are also required to have a bituminous surfacing 24 feet wide contained within a 60 foot right of way. Right-of-way widths may be reduced to 50 feet if there is extenuating environmental or physical constraints on a property. Current city policy also allows the construction of private streets. Up to four single-family residences may be served via a private street if it is demonstrated to be unfeasible or unnecessary to construct a public street. In such cases,30 feet of ease- ment is required with the roadway consisting of a 20-foot wide paved surface. Multi-family private streets require 24 feet of paved surface in a 40-foot easement. Commercial, industrial,and office development may be served by 26-foot wide paved A, private streets within a 40-foot wide access easement. 143 6.11 1 Pavement Management Historically,the emphasis for growing communities has been building roads and implementing preventive maintenance due to 51- the relatively new network system. But as street networks age,the new focus is on maintaining and preserving existing pave- Lment surfaces. A pavement management program is a systematic approach to using a series of pavement treatment options F' over time. One treatment at the right time will improve the quality of the pavement surface and extend the pavement life, but the true benefits of the pavement management program are realized when there is a consistent schedule. An effective pavement management program integrates many preventive maintenance strategies, rehabilitation and recon- struction treatments. The goal of such a program is to extend pavement life and enhance system-wide performance in a cost-effective and efficient way. Studies show that preventative maintenance is six to ten times more cost effective than a minimal maintenance program with only some rehabilitation and reconstruction maintenance strategies used. The City of Chanhassen recognizes that the street infrastructure is an asset to the community that needs to be maintained. In 2004,the city began a pavement management program to identify long-term needs of the city street network. The objective of the program is to have a long-term pavement management plan that can realistically be funded and does not have significant peaks and valleys in the annual budgets.Also,the program will help identify projects long term that will give residents some idea when their street will be proposed for improvements. The program is structured to propose projects when projects are warranted and to have a consistent methodology for proposing street improvement projects. Over the past years, staff has used this information to ascertain which streets require improvements and what type of improvement is required. There are three main types of pavement treatment options: 1. Preventive Maintenance: This item includes filling potholes, patching, crack sealing and seal coating. 2. Rehabilitation: Performed to correct deficiencies that occur in pavements such as extensive cracking and potholing. �' This type of maintenance includes mill and overlays. 3. Reconstruction.' This item is performed when corrective maintenance is no longer appropriate. Studies conducted by a number of agencies indicate that as pavement conditions decrease, the cost for the appropriate im- provements significantly increases. A typical graph of a pavement degradation curve taken from the American Public Works Association is shown above.This graph shows that it is more cost effective to have pavement repaired with preventative main- tenance than it is to wait until the pavement needs reconstruction. Bridges Bridges meeting the State of Minnesota definition are inspected according to the National Bridge Inspection Standard and are typically inspected every one to two years depending on their condition.

The city's transportation policies are supportive of metropolitan policies and consistent with the fa- plans and programs of the Metropolitan plan, State systems and Carver County's plan and relate directly to the objectives of the City of Chanhassen. Goal To create an integrated, multi-modal transportation system which permits safe,efficient and effective movement of people and goods while supporting the city's development plans,and complementing the metropolitan transportation system that lies within its boundaries. Transportation Policies General Thoroughfares and major routes should be planned so as to reduce conflicts between external traffic and local traffic while facilitating development in the community. Through the development review process,the city will strive to discourage development from occurring within the designated roadway corridors as well as limiting access to collector streets, minor arterials, intermediate arterials and principal arterials. Access points to the regional roadway system should be adequately controlled in terms of driveway openings and side street intersections. Promote safe and convenient access connections between the highway system and major commercial areas, industrial uses, and residential neighborhoods. Roadways -� Encourage multiple uses of right-of-way areas accommodating various modes of transportation. New roadway facilities should be constructed in conjunction with new developments and designed according to the intended function.They should be planned and designed to be compatible with the surrounding environment. Existing roadways should be upgraded when warranted by demonstrated volume,safety or functional needs. Roadways shall also be maintained and repaired to ensure the greatest possible useful life. Residential street systems should be designed to discourage through traffic and to be compatible with other transportation modes including transit, bicycle and walking. The city will implement roadway design standards and inspection practices which ensure proper construction. Streets shall be designed and operated to enable safe access for all users, including pedestrians, bicyclists, motorists and transit riders of all ages and abilities. Transit The city encourages all forms of ridesharing in order to reduce vehicle miles of travel, reduce petroleum consumption,and im- prove air quality. The city will review all major new developments in light of the potential for ridesharing including bus accessibility, preferential parking for carpools/vanpools,and mixed use development. The city will consider support for Federal, State, Metropolitan,and local efforts directed toward the access of rail transit for the community,the region,and the state. --� The city encourages cooperation with the Metropolitan Council and Southwest Transit Commission in order to provide future a transit service to and within the community. The city will support the development of park and ride facilities that encourage transit use. • 145 C N C C) s E 0 U N C G) N N �U 0 U 146 5_ t � 1 f Ii Chapter 7 :. ..5„ ,. .. ._..„. sewer i, i, \ , ._F : _ ,.. . , ,. �•c� k - rrwcC • s+. tit+? r` -Y _ S \ . s' .,,,i.... .

The plan is also intended to serve as an inventory of the City's existing sanitary sewer facilities and an updated guide for completing the future sanitary sewer trunk system improvements. The City is divided into eight major sanitary sewer service areas or districts as shown in Figure 3.2 in Appendix A. For the purpose of sanitary sewer planning,these major districts are further divided into sub-districts based on both lift station and gravity sewer service areas as shown in Figure 3.3 in Appendix A. Each sub-district contributes wastewater flow to the san- itary sewer collection system dependent upon a variety of parameters. These parameters include but are not limited to land use, population density,wastewater generation rates, development restrictions,wetlands,and dedicated green space. Approximate future trunk facility locations were determined based on the topography of undeveloped areas.An objective to planning the trunk sanitary sewer system is to minimize the number of trunk lift stations,while keeping the maximum depth of gravity sewers to realistic depths.The existing and proposed system layout is also shown on Figure 3.4.The system layout is general in nature and exact pipe alignments and lift station locations will be determined by the actual conditions at the time of final design. It is important that the general overall concept and sizing plan is utilized to assure an economical and adequate future system. A 22-year capital improvement plan (CIP)was developed for the completion of the trunk system. These trunk facilities include all gravity sewer mains for each sub-district, lift stations, and force mains. The CIP includes costs for each trunk improvement project; however,the approximate trunk costs do not include the cost of installing lateral sewers for develop- ment.The cost for lateral improvements would be funded directly through assessments to the development or redevelop- ment.The following table summarizes the proposed 22-year CIP and associated costs: E 0 U 0 148 Figure 7.1 I CAPITAL IMPROVEMENT PLAN SUMMARYcp Improvement Description I Extended Cost co 2018 Inflow and Infiltration Abatement $200,000 Sanitary Sewer Replacement $150,000 Lift Station#18,26 $75,000 Subtotal $425,000 2019 Inflow and Infiltration Abatement $200,000 2010 MUSA Lift Station $1,900,000 Sanitary Sewer Replacement $50,000 Lift Station#16 $50,000 Subtotal $2,200,000 2020 Inflow and Infiltration Abatement $200,000 Sanitary Sewer Replacement $250,000 Lift Station#22 $50,000 Subtotal $500,000 2021 Inflow and Infiltration Abatement $200,000 Sanitary Sewer Replacement $50,000 Lift Station#2,17 $75,000 Subtotal $325,000 2022 Lower Bluff Creek Trunk Sanitary Sewer $10,800,000 Inflow and Infiltration Abatement $200,000 Sanitary Sewer Replacement $250,000 Lift Station#13 $50,000 Subtotal $11,075,000 2023 Inflow and Infiltration Abatement $200,000 Sanitary Sewer Replacement $50,000 Lift Station#1,20 $120,000 Subtotal 9370,000 2024 Inflow and Infiltration Abatement $200,000 Sanitary Sewer Replacement $150,000 Lift Station#7 $50,000 Subtotal $400,000 2025-2030 2026-2030 Sanitary Sewer I/I Rehabilitation $1,000,000 2026-2030 Sanitary Sewer Reconstruction Program $850,000 Lift Station No. Improvements $455,000 Subtotal $2,305,000 2031-2035 2031-2035 Sanitary Sewer I/I Rehabilitation $1,000,000 2031-2035 Sanitary Reconstruction Program $650,000 Lift Station No. Improvements $330,000 Subtotal $1,980,000 2036-2040 2036-2040 Sanitary Sewer Ill Rehabilitation $1,000,000 r 2036-2040 Sanitary Reconstruction Program $850,000 Lift Station No. Improvements $800,000 Subtotal $2,650,000 s�g Total Capital Improvements Plan Costs $22,445,000 Costs are for budgeting g g purposes only, and are subject to change as projects are studied, designed and constructed. » Project Costs include 10%for construction contingency and 25% indirect costs where applicable. » Costs are estimated based on 2017 construction costs. o U 149 17.21 Introduction ..., `/) Purpose The purpose of this study is to provide the City with an updated plan to serve future development and to identify existing system facilities and deficiencies. Scope The scope of this study includes population and sanitary sewer flow projections for the City of Chanhassen through the year 2040.The potential 2040 service area was defined as areas that can be feasibly served by sanitary sewer in the future and was based on the current Land Use Plan prepared for the City's Comprehensive Plan. The 2040 service area for the City is considered to be the full build-out of the current City Limits. Based on the 2040 service area, sanitary sewer districts and sub-districts were defined. Existing and future sanitary sewer flow rates were calculated for each sub-dis- tricts based on the respective land uses. Projected sanitary sewer flow rates were used to analyze the existing trunk system capacity and size future trunk system facilities. Future trunk improvements were defined with the intention that the trunk system would serve the 2040 service area. An approximate layout of potential trunk system improvements along with an opinion of probable cost is provided. Future improvements were prioritized and incorporated into a Capital Improvement Program(CIP) based on an approximate phasing plan provided by the City Staff. Data Available In preparing this report,the following sources of information were utilized: » Existing Sanitary Sewer GIS Information • Sanitary Sewer As-builts » City of Chanhassen Comprehensive Sewer Policy Plan, dated November 2008, prepared by WSB &Associates » City of Chanhassen Infiltration and Inflow Reduction Plan, dated June 12, 2006, prepared by WSB &Associates » County Road 61 Corridor Plan, dated December 2, 2014, prepared by SRF Group in association with Hoisington Koegler Group » 2040 Thrive MSP Water Resources Policy Plan EXISTING CITY SANITARY SEWER SYSTEM Overall Sanitary Sewer Service Area Typically, sanitary sewer systems consist of two elements; collection and treatment. Collection systems include sewer ser- vices,trunk sewer pipe, manholes, lift stations, and forcemains which collect the sewer flows from private resident, commer- c, cial, and industrial properties within a city.Treatment systems include the biological or chemical treatment in order to remove targeted contaminants from the wastewater. I U 150 The City of Chanhassen's existing sanitary sewer system is a collection system only;the Metropolitan Council Environmen- tal Services(MCES) provides treatment for Chanhassen's entire sanitary sewer flows. MCES is also responsible for major a1 `— trunk facilities conveying wastewater across City boundaries to regional treatment facilities. All wastewater flows from the U) City of Chanhassen enter the MCES interceptor system and is conveyed to the MCES Blue Lake Wastewater Treatment Plant(WWTP) located in the City of Shakopee, just north of Highway 101. The sanitary sewer service area is defined as the area from which wastewater flows are collected by the City's regional system. The existing serviced area within the City of Chanhassen is comprised of approximately 10,600 gross acres which includes the lakes, open park land, and road right-of-ways. This service area is shown in Figure 3.2. Sanitary sew- er service districts (districts)were developed within the City boundaries based on gravity service and lift station service areas. The existing serviced area has been developed within several districts, many of which are not fully developed. Gravity Sanitary Sewer The City of Chanhassen gravity sanitary sewer system consists of 6-to 36-inch diameter vitrified clay pipe(VCP), acryloni- trile butadiene styrene (ABS), reinforced concrete pipe(RCP), ductile iron pipe(DIP), and polyvinyl chloride(PVC) plastic sewer pipe. The original sanitary sewer system for the area southwest of Lotus Lake was constructed in the 1950s and consisted of two lift stations. Following the initial construction, a majority of the system was constructed in the 1970s. The existing gravity sanitary sewer system appears to be in good overall condition; however, limited televising inspec- tions have found root penetrations at joints, cracked pipe, leaking manholes and castings, as well as mineral deposits. In recent years,the City of Chanhassen has been identified as having excessive infiltration and inflow(III) by MCES. The City is currently included on the MCES "List of Communities with Observed Excess I/I,June 30, 2006." The City was also assessed a surcharge by MCES according to the adopted MCES 2007 Surcharge Policy. The City of Chanhassen devel- oped an Infiltration and Inflow Reduction Plan dated June 12, 2006 which identified a number of gravity sanitary sewer improvements to reduce the amount of I/I entering the Cities system. The gravity sanitary sewers are directed to several MCES interceptors described in Section 4 that conveys wastewater to the Blue Lake WWTP. The existing gravity sanitary sewer trunk mains(8-inch diameter and larger)and the MCES inter- ceptor are shown on Figure 3.1. Lift Stations The City of Chanhassen sanitary sewer system consists of 31 lift stations ranging from a small 16 gallons per minute (gpm)grinder station to a large 1,448 gpm lift station. The lift station capacities vary depending on size of service area. The locations of the existing lift stations are shown on Figure 3.1 and the following Table summarizes capacity information for each of the lift stations: g I 0 0 m I L 1r L 151 tt Figure 7.2 I EXISTING LIFT STATION INFORMATION co General Lift Station Information General Sewer Shed Information Lift Year Approx.

Existing system as-built information was used to develop the model and determine g. system capacity. Average day and peak flows were calculated by determining the existing developed area in each district, area of each existing land use, number of existing units, and assuming a flow generated for each land use. (cont.) 152 The model was calibrated by reducing the flow generated for each land use until the total system flow matched sewer flows metered by MCES. The existing system model includes the following parameters: co • Existing sewer mains— 10-inch diameter and larger u Existing trunk lift stations » Existing trunk main flows(MCES) Figure 3.5 illustrates the remaining pipe capacity resulting from the 2006 analysis trunk mains. Modeling results indicated two sections(of 23 sections)of the 36-inch trunk main parallel to the MCES interceptor flowing east along the north side of Lake Susan near Highway 101 exceeded capacity as shown on Figure 3.5.The model indicated a slight surcharge at the manholes in the two sections where existing flows exceeded capacity, however the capacity of the overall trunk system is adequate. The MCES Lake Ann interceptor exhibited a few sections exceeding capacity; however, MCES is responsible for monitor- ing flows and determining deficiencies for this main. Table 3.2 All trunk lift stations(with influence lines greater than 10-inches diameter)with the exception of Lift Station No. 7 exhibit adequate capacity.

Some of these areas are de- veloped with one or two acre lots that could be developed or subdivided with sanitary sewer service. Figure 3.6 in Appendix A presents the lots which currently utilize septic systems. The areas are primarily located in the districts south of the Highway 212 corridor. The remaining existing septic systems are scattered throughout the remainder of the City in areas with larger lots. --� MCES SANITARY SEWER SYSTEM The majority of the wastewater generated from the City of Chanhassen is conveyed to one of two MCES interceptor sew- ers, identified as the Shorewood Interceptor(7017)and the Lake Ann Interceptor(7138). Shorewood Interceptor The Shorewood Interceptor is a combination forcemain and gravity sewer interceptor, which begins at the MCES L21 Lift Station near Lake Virginia and flows eastward through Shorewood, Excelsior, Greenwood, and Tonka Bay. There are four extensions of the Shorewood Interceptor, which extend southward to the north boundary of Chanhassen(information ob- tained from the 2006 Comprehensive Sewer Policy Plan). Shorewood interceptor extension 7017-1 is a 15-inch diameter RCP gravity flow sewer extending northeasterly from the Chanhassen boundary at Washta Bay Road along Pleasant Avenue to the northwest side of Mary Lake in Shorewood to the major interceptor. Shorewood interceptor extension 7017-2 is a 9-inch diameter PVC forcemain that extends from the Chanhassen boundary at Chaska Road to the west shore of Galpin Lake in Shorewood to the major interceptor. g N Shorewood interceptor extension 7017-3 is a combined gravity and forcemain facility that flows north from the Chanhassen boundary along Christmas Lake Road through a 15-inch diameter RCP to a lift station, then through a 9-inch diameter PVC pipe and an 8-inch diameter DIP to the major interceptor. Shorewood interceptor extension 7017-4 is a 12-inch diameter RCP gravity flow sewer extends between Christmas Lake and Silver Lake from the Chanhassen boundary to the Shorewood Interceptor. o Wastewater generated from the Northern area, the area on the north side of Lake Lucy, and the area around the north and west sides of the Lake Minnewashta area flow north to the Shorewood Interceptor and is ultimately treated at the Blue Lake Wastewater Treatment Facility in Shakopee. 154 Lake Ann Interceptor The Lake Ann Interceptor(7138) is an MCES sewer that serves Chanhassen in the Bluff Creek, Rice Marsh Lake, Lake cn Susan, Lake Ann, Lotus Lake, Lake Lucy, and Lake Riley vicinity. The Lake Ann Interceptor sewer system was construct- ed in three phases and was completed in 1988. The interceptor extends southeast, beginning at Trunk Highway 41 near the north City limits and approximately 4.5 miles to the Red Rock Interceptor at the Chanhassen/Eden Prairie border. The City's Lake Ann trunk sewer is parallel to the MCES trunk sewer between the Red Rock Interceptor and Highway 5. The Red Rock Interceptor starts at the termination of the Lake Ann Interceptor and continues southeasterly through Eden Prairie where it discharges into the Purgatory Creek Interceptor and eventually to the Blue Lake Wastewater Treatment Facility in Shakopee. During the 2007 SewerCAD model analysis for the existing City of Chanhassen sanitary sewer system and as discussed in Section 3.4, the MCES Lake Ann interceptor exhibited a few sections exceeding capacity; however, MCES is responsi- ble for monitoring flows and determining deficiencies for this main. 7.3I Land Use Land Use Breakdown The current land use plan for the City of Chanhassen is shown in Chapter 2, Figure 2-4. This plan was developed by the City and separates the planning area into eleven (11)different land use categories. Land use is a critical factor in deter- mining future sanitary sewers alignments and sizes due to the fact that different land uses generate different wastewater flow rates. The following table presents the current City land use breakdown and the associated abbreviations: Figure 7.4 I LAND USE SUMMARY Land Use Designation Abbreviation Residential—Large Lot RLL Residential—Low Density RLD Residential—Medium Density RMD Residential—High Density RHD Commercial C Office 0 Office/Industrial O/I Parks/Open Space P/OS Public/Semi-Public P/SP Mixed M Agricultural A Existing Developed and Developable Areas The area within Chanhassen's City planning area is approximately 21 square miles or 13,700 acres. The existing area within Chanhassen with sewer service is approximately 16.6 square miles or 10,600 gross acres. For sewer planning purposes, land that is not served by sanitary sewer is considered not developed and not all of this acreage is considered developable. Undevelopable land use categories include open space and water. Existing developed and undevelopable areas were subtracted to obtain developable acreage. Developable acres are t shown on Figure 5.1 along with the existing sewer service area. This is identified as "Gross" Developable Acreage because it includes roads and common or public/park areas potentially included in developments. Roads,common areas,and parks e typically consume 25%to 30%of the gross area within a development. 155 tt GROWTH PROJECTIONS Projected Residential Growth Historical growth data for the study area from the Minnesota State Demographer's office is included on Table 6.1. The City of Chanhassen exhibited stable growth between 1900 and 1960; however, it grew exponentially between 1960 and 2000 with approximately 73%growth between 1990 and 2000.

Based on the data provided below,there would be an approximately 16%to 19% growth in population every 10 years. It is assumed that as development occurs,sanitary sewer service will be extended to the new development. Sanitary sewer "1 service will also be extended to current large lot developments based on need such as failing septic systems. Sanitary sewer service would only be extended to new developments and existing large lot developments that have been incorporated into the MUSA area.

These properties are included in the sewered household category. 156 Projected Non-Residential Growth 3 Non-residential customers are located in the following land use areas: Commercial, Office, Office/Industrial, Industrial, Mixed in Use, Parks/Open Land,and Public/Semi Public. Tracking the exact acreage developed each year for the preceding land uses is difficult; however, it is possible to track the number of total non-residential connections based on water use records. Typically,the above land use categories are grouped into two water use types,commercial and industrial. Since it is not pos- sible to relate land use categories to water use records,the previously listed land use categories have been grouped together as non-residential for determining growth rates. To project future non-residential growth, some trends over the past few years can be analyzed. Table 6.3 illustrates the growth in non-residential water connections over the past ten years, and the percentage of non-residential connections relative to residential connections for the City of Chanhassen water system. Figure 7.7 I NON-RESIDENTIAL HISTORICAL GROWTH Non- Non- Residential Percent non- Year residential non- residential Residential annual residential connections annual nua connections growth connections 2007 251 6,545 3.69% 2008 345 37.45% 6,931 5.90% 4.74% 2009 342 -0.87% 7,019 1.27% 4.65% 2010 431 26.02% 7,145 1.80% 5.69% 2011 426 -1.16% 7,229 1.18% 5.56% _ 2012 382 -10.33% 7,310 1.12% 4.97% 2013 341 -10.73% 7,530 3.01% 4.33% 2014 292 -14.37% 7,612 1.09% 3.69% 2015 295 1.03% 7,780 2.21% 3.65% 2016 296 0.34% 7,904 1.59% 3.61% Average 4.46% Historically there is a correlation in the ratio of non-residential to residential connections.The ratio has averaged 4.05%over the last five years. Based on a ratio of non-residential to residential connections of 4.05%,Table 6.4 was developed to project future non-residen- tial connection growth in a similar fashion to Table 6.2 projecting future population. Figure 7.8 I NON-RESIDENTIAL GROWTH PROJECTIONS Year Population Residential Non-Residential Connections Connections 2016 24,951 7,904 296 2020 26,700 9,200 373 2030 31,700 11,100 450 2040 37,100 13,300 539 Existing Wastewater Flows z a Future sanitary sewer flows, in conjunction with available slope,govern the capacity of sanitary sewers.To determine future sanitary flows existing water demand and MCES recommendations were considered.MCES typically estimates 274 gpd/connec- g tion or 75 gallons per capita per day(gpcd)for residential estimates and 800 gallons per acre per day(gpad)for non-residential 8 developments. E Total existing City wastewater flows are not measured for individual users;the total flows are only measured by MCES at the City flow meter for the entire City of Chanhassen.Wastewater flows are therefore not categorized by land use type. However,the City of Chanhassen does collect water demand data. Water demand data by customer type for 2010-2016 is shown below in Table 7.1.The actual annual wastewater generated is also shown in the following table,along with the percent of wastewater gener- o ated per actual gallons of water used. From the information provided,the wastewater generated during the years 2010 to 2016 ' ranged from 58%to 83%of the actual water usage. 157 tt Figure 7.9 I WATER DEMAND BY CUSTOMER CATEGORY N Customer Category 2010 2011 2012 2013 2014 2015 2016 Residential 689,522 738,107 863,567 764,214 672,717 667,903 630,530 (1,000 Gal) Commercial 465,669 180,144 176,868 161,122 147,411 138,082 112,660 (1,000 Gal) Industrial 97,806 120,152 107,630 94,111 86,864 84,117 62,132 (1,000 Gal) Other' 21,456 19,744 29,005 22,948 22,257 20,890 107,052 (1,000 Gal) Total (1,000 Gal) 971,453 1,058,147 1,117,070 1,042,395 929,249 910,992 912,374 Wastewater Flow 757,900 784,200 652,800 725,600 721,800 620,200 753,500 (1,000 Gal)2 of Wastewater 78% 74% 58% 70% 78% 68% 83% to Water Usage Average Water 2.7 2.9 3.1 2.9 2.5 2.5 2.6 Demand (MGD) Average Wastewater Flow 2.1 2.1 1.8 2.0 2.0 1.7 2.1 (MGD) The other water usage category includes institutions, schools, and parks. The total annual wastewater flow was provided by MCES and based on the flows that the City of Chanhassen was billed for. The industry standard design for water consumption is 100 gallons per person per day and for sewer it's 75 gallons per person per day which accounts for losses occurring largely due to lawn watering; therefore for communities that do not have excessive I/I the average wastewater flow is approximately 75%of the water demand. Table 7.2 summarizes the wastewater to water consumption since 2000. As the City of Chanhassen continues to implement the I/I reduction plan, it is expected that the percent of wastewater flow to water demand will decrease and will become consistent with other communities that currently do not have excessive I/I.

As discussed previously, MCES typically uses 75 gpcd. Based on the residential water use from Table 7.1 and the actual percentages of wastewater to water usage,Table 7.4 indicates that the average Chanhassen residential wastewater flow is below 75 gpcd.

Assumes unsewered population is approximately 795. Non-Residential Flow Rates d .z Non-residential wastewater generators consist of Commercial, Office, Office/Industrial, Industrial, Mixed Use,and Public/ Semi Public land uses.As discussed previously, it is not possible to separate land use areas based on water use records. a Therefore, existing wastewater flows were developed based on the water usage records and allocating the remaining water 0 demand flows to each non-residential acre. Water demand was used because it can be separated by non-residential and residential use based on provided data.Verifying water usage records and applying the MCES assumption for non-residential users of 800 gpd is a reasonable assumptions for overall planning. 1 It is possible a large user could develop within the system;therefore, some laterals may need to be increased in size at the t time of construction.The cost to install larger laterals has not been accounted for as a part of this plan.These developments o would need to be reviewed on a case-by-case basis as the development occurs. :' U 159 Peak Flow Factors cn The sanitary sewer collection system must be capable of handling not only average flows, but also the anticipated peak flows. These peak flows can be expressed as a variable ratio applied to average flow rates. This variable ratio,called the peak flow factor, has been found to decrease as the average flow increases. The peak flow factors applied in this study were based on typical MCES supplied peaking factors. They are generally considered conservative, and are widely used for planning in municipalities throughout the twin cities metropolitan area. Appendix B lists the peaking factors used for this study. Infiltration and Inflow(I/t) Infiltration is clear water that enters the sanitary sewer system through defects in the sewer pipes,joints, manholes,and service laterals. Water that enters the sewer system from cross connections with storm sewer, sump pumps, roof drains,or manhole covers is considered inflow. The quantity of I/1 entering a wastewater collection system can be estimated utilizing wastewater pumping records,daily rainfall data,and water usage characteristics. Water from inflow and infiltration can consume available capacity in the waste- water collection system and increase the hydraulic load on the treatment facility. In extreme cases,the added hydraulic load can cause bypasses or overflows of raw wastewater. This extra hydraulic load also necessitates larger capacity collection and treatment components,which results in increased capital, operation and maintenance,and replacement costs. As sewer system age and deteriorate, I/I can become an increasing problem. Therefore, it is important that III be reduced whenever it is cost effective to do so. The MCES has established wastewater flow goals for each community discharging wastewater into the Metropolitan Disposal System(MDS)based on average day flows and allowable peaking factors. These enforced wastewater flow goals are aimed at reducing excessive I/I within the City's sanitary sewer system and also the MCES interceptor system. In February 2006, MCES adopted an I/I Surcharge Program which requires communities within the MCES service area to reduce or minimize excessive Ill over a period of five years. In the case that communities exceed the wastewater flow goals set by MCES during the five-year surcharge period, the community will be assessed a surcharge for flows above the goal. The City of Chanhassen was identified by the MCES as having excessive III during the development of the I/I Surcharge Program. As part of the MCES surcharge program,the City of Chanhassen has the ability to recover or avoid the imposed surcharges. Surcharges can be avoided by taking official steps to reduce excess Ill through planned City(or private)fund expenditures. In addition,costs spent on repair or reconstruction of the MCES interceptor may be directly credited to the City of Chanhassen's surcharge amount. The City of Chanhassen's goal is to abate I/1 in a measurable manner: reducing wastewater flows such that they are 75%or less than the water consumption. Table 7.5 shows the percentage of wastewater to water consumption for the last 17 years. From 2000 to 2006, six of the seven years monitored exceeded 75%. Over the next five years two years exceeded the thresh- old. From 2012 to 2016 two years exceeded the 75%threshold.

Every year a portion of public sanitary sewer infrastructure-manholes and laterals-is g `-- inspected and the necessary repairs are made. Section 19-44 of the City Code is used to enforce the City's Ill policies with co regards to private sewer infrastructure and can be found in Appendix C. Public Sanitary Sewer and Manholes Annually the City reviews the condition of a portion of the public infrastructure,televising the sewer pipe and inspecting manholes. The sections chosen include pipe and manholes within the next year's street improvement project and areas that have been identified as high potential for I/I, such as pipe located next to a surface water feature. Issues identified are repaired or replaced. Examples of repair work includes installing I/I barriers and gasketed manhole covers, chemical grout,and short lining. Typically,the City reconstructs approximately one mile of streets in even-numbered years based on the condition of the street,water main and sanitary sewer. In odd-numbered years the City rehabilitates between three and six miles of streets. It is the City's policy to install drain tile throughout street reconstruction projects and in select areas in rehabilitation projects. Drain tile desaturates the street subgrade, reducing the groundwater available for infiltration into the sanitary sewer system. The drain tile also provides homeowners an option to connect their sump pump discharge which reduces inflow into the sanitary sewer system. Private Sewer Services Public sewer televising includes a visual of the service wye. As of 2014 the City offers residents within street project areas the opportunity to have their sanitary sewer service from the home to the public sewer televised. Participation is voluntary and is intended to identify services that are a source of Ill or are in need of other repairs. This service will continue to be offered to residents within street improvement project areas. Private Sump Pump and Drain Tile Illicit Connections According to information provided by the Metropolitan Council, prior to 1969 the Plumbing Code allowed sump pumps to dis- charge into the sanitary sewer and perimeter drain tile was permitted to be directly connected to the sanitary sewer service. According to the 2016 records there were 733 buildings within the City that were built in or before 1969;the remaining 8,097 homes within Chanhassen were built after 1969. Of the homes built before 1969,62%of the service wyes and 1%of the service laterals have been televised. Figure 7.1 in Appendix A shows the properties which contain buildings constructed in or before 1969. In effort to reduce the number of illicit discharges(inflow)to the sanitary system the City inspected 924 homes as part of the Sump Pump Inspection Program in 1996:84%of homes were in compliance,meaning their sump pump was not connected to the sanitary sewer. Throughout the next seven years,the City reinspected the noncompliant properties to ensure that the sump pump discharge was disconnected from the sanitary sewer. More detailed information including specific projects and associated costs are included in the prepared III reduction plan. Total annual costs for I/I reduction efforts are included in the overall sanitary sewer Capital Improvements Plan prepared with this comprehensive study. A copy of the detailed I/I Capital Improvements Plan from the I/I reduction plan is included in Appendix C. o The clearwater flow from residential uses is estimated using the data presented in Table 7.3. Design assumptions for sewer discharge is 75 gallons per person per day and 100 gallons per person per day for water consumption,or sewer discharge is 75%of water consumption. Using this rationale wastewater flow in excess of 75% is an estimation of clearwater flow and is .2 `.. summarized in Table 7.6. 161 ( Figure 7.14 I HISTORIC RESIDENTIAL WASTEWATER FLOW RATES cn Actual Estimated Estimated Percent of Amount Residential Clearwater Year Wastewater Above 75% Wastewater Flow to Water Threshold Flow (gal/day) Usage (gal/day) 2010 78% 3% 1,473,499 44,205 2011 74% - 1,496,436 - 2012 55% - 1,301,265 - 2013 70% - 1,465,616 - 2014 78% 3% 1,437,587 43,128 2015 68% - 1,244,312 - 2016 83% 8% 1,433,808 114,705 7.41 Sanitary Sewer Districts To develop the future sanitary sewer trunk system the ultimate potential service area was divided into major service areas or districts and then dividing those major service districts into sub-districts. Generally the selection of these areas is governed by existing topography and/or other existing features such as roadways.The ultimate potential service area for Chanhassen is divided into eight major sanitary sewer districts: Minnewashta(MW), Bluff Creek(BC), Lake Ann(LA), Lake Lucy(LC), North (NO), Lotus Lake(LL), Lake Riley(LR),and Lower Bluff Creek(LB). Figures 3.2 and 3.3 in Appendix A show the major sani- tary sewer districts and the sub-districts. The following figure details the major sanitary sewer districts: The existing and projected flows for each sanitary sewer district is presented in Appendix B.The existing flows noted in Ap- pendix B are higher than the sewer flow rates provided by the Metropolitan Council.The difference between calculated and realized sewer flows can be attributed to the fact that properties within each land type can contain undevelopable acreage such as wetland, storm water feature or steep slopes which cannot be readily deleted from the property area. Minnewashta District(MW) The Minnewashta(MW)Sewer District includes the area around the south, west, and north sides of Lake Minnewashta. There are approximately 1,200 acres of developed land consisting of low density residential and commercial uses, includ- ing approximately 40 acres of single family residential land within the City of Victoria. The district also includes park/open space and significant acreage of public/semi-public land within the Minnesota Landscape Arboretum property. Approxi- mately 20 acres of low density residential developable land remains within the MW Sewer District. The MW Sewer District is subdivided into seven sub-districts.The flows from the MW district are collected by several sewer lines ranging in size from 8-inch to 10-inch pipe.There are six lift stations that service the MW Sewer District as summarized in Table 8.1. ell ar a E 0 U C N C C C) 0 O U 162 Figure 7.15 SANITARY SEWER DISTRICTS r) 1011 DRAFT Sanitary Sewer Districts • t � 1 -: - i♦ r .�,y t ' i K • • th Lel i 1 Not 19 soak • Miele nn cna U*ir..

Bluff Creek District(BC) The Bluff Creek(BC)Sewer District includes the area from the east side of Lake Minnewashta and extends southeasterly along the Chanhassen/Chaska border to the Highway 212 corridor. There are approximately 1,250 acres of developed land and 400 acres of developable land within the BC Sewer District. The BC District is partially developed with a combination of low and medium density residential, large lot residential, parks/ open space, public/semi-public, and office/industrial properties. The BC Sewer District is subdivided into 11 sub-districts. The wastewater generated is collected by gravity sewers ranging from 8-inches to 21-inches diameter. There are three lift stations within the BC Sewer District: Lift Stations 19, 24 and 26. Lift Station No. 19 serves the BC-2 sub-district and Lift Station No.26 serves the BC-3 sub-district. All of the wastewater from the BC sub-districts flows to Lift Station 24,where it is then pumped north to an 18-inch trunk sewer in the Lake Ann Sewer District Lake Ann District(LA) The Lake Ann District(LA)Sewer District includes the area that runs through the central part of Chanhassen.There are approximately 1,656 acres of existing developed land and 295 acres of developable land within the LA Sewer District. The LA District is sub-divided into 11 sub-districts. The majority of the sub-districts have been developed but there will still be need for lateral sewer lines as LA-4, -5, and-6 are sub-districts that are not fully developed. The LA District consists of low, medium, and high density residential properties as well as large lots, park/open space, public/semi-public, and office industrial areas. The wastewater generated in the LA District is collected by gravity sewers ranging from 8-inches to 36 inches in diameter. There are five existing lift stations within the LA Sewer District: Lift Stations 23, 27, 29, 30, and 31. Lift Station No 23 is a n small station within the LA-4 sub-district that serves Lake Ann Park and discharges to Lake Susan Sub District 11. Lift Sta- tion No. 27 serves the LA-7 sub-district and discharges to LA-6. Lift Station No. 29 was constructed to serve approximately ;i nine large lots in the southern part of LA-3 sub-district, however its use has been very minimal as only services one home at othis time. Lift Station 30 serves the LA-9 sub-district and discharges to LA-8. Lift Station 31 serves approximately 28 single E family lots in the southern part of LA-3 sub-district. The MCES Lake Ann Interceptor runs southeast through the center of the LA Sewer District. The City's major trunk line, which ranges in size from 21-inches in diameter to 36-inches in diameter, parallels the MCES Lake Ann Interceptor from 5 State Highway 5 to near Market Boulevard, where it discharges into the Lake Ann Interceptor. **6 164 Lake Lucy District (LC) The Lake Lucy(LC)Sanitary Sewer District is located around the north side of Lake Lucy. The LC District is not subdivided in v) to sub-districts due to its size. There is approximately 91 acres of existing developed land within the LC District,which is all low density residential. A 10 acre parcel in the southwest corner of the LC District may further subdivide in the future. Sanitary sewers 8-inches in diameter collect the wastewater and direct it to Lift Station No. 25. Lift Station No. 25 is the only lift station within the LC District, which collects the entire wastewater generated and pumps the wastewater to the North District North District (NO) The North District(NO)is located along the north border of the City and extends east from the Minnewashta District to the eastern border of the City. The NO District also includes the area along the northeast side of Lotus Lake and is fully devel- oped. There is approximately 725 acres of existing developed land within the NO Sewer District. The existing development within the NO District consists of low density residential, park/open space, and public/semi-public uses. This district also includes approximately 17 acres of low density residential within the City of Shorewood. The only properties that may be de- veloped in the future are low density residential lots that lie within sub-districts NO-7 and NO-8. The NO District is subdivided into 12 sub-districts. The wastewater generated is collected by gravity sewers ranging in size from 8-inches to 15-inches in diameter. There are six lift stations within the NO District and include Lift Stations 5, 13, 14, 15, 16,and 21. Lotus Lake District(LL) The Lotus Lake District(LL)is located along the western and southern sides of Lotus Lake and is divided into 10 sub-districts. Most of the area within the LL District is developed and is composed of low and high density residential, parks/open space, public/semi-public, office/industrial and commercial properties. There is approximately 925 acres of developed land within the LL Sewer District. Sub-district LL-3 has approximately 8 acres of developable low density residential land. LL-7 has one, 1.2 acre commercial property that is possible for redevelopment. The wastewater generated is collected by gravity sewers ranging in size from 8-inches to 21-inches in diameter. There are seven lift stations within the LL District and include Lift Stations 1, 2, 9, 10, 11, 12 and 22. Lake Riley District (LR) The Lake Riley District(LR) is located around the north,west and south sides of Lake Riley. There are approximately 485 acres of developed land and 40 acres of developable land within the LR Sewer District. The potential future development within the LR District is around the US Highway 212 corridor and Great Plains Boulevard. The developed areas consist of low and high density residential, large lots, park/open space and mixed use properties. Sub-districts LR-3 and LR-4 have areas of potential low and medium density residential as well as mixed use developable properties. The LR District is subdivided into five sub-districts. The wastewater is collected by gravity sewers ranging in size from 8-inch- a es to 36-inches in diameter. There are two lift stations within the LR District and include Lift Station 17 and 18. Lower Bluff Creek District(LB) The LB District is located south of Lyman Boulevard between Powers Boulevard and Great Plains Boulevard, and between Pioneer Trail and the southern City limits.This area within the district is partially developed with very little City sewer service. There is a strong possibility for redevelopment, namely along the Highway 212 corridor,as well as the Bluff Creek Golf Course. . There are approximately 610 acres of developed land and 1,000 acres of developable land within the LB Sewer District. 0 165 The LB District is subdivided into five sub-districts. An 8-inch sanitary extends along 96th Street to Lift Station No.20 and gserves the existing developed lots within LB-4. Lift Station No. 20 pumps wastewater through a forcemain that runs north ''\ N along Great Plains Boulevard that discharges to the Lake Riley District. There is also an existing 15-inch and 18-inch trunk sewer line that was constructed along Pioneer Trail and Powers Boulevard, however this existing trunk sewer does not serve any development at this time. Development of The land within this sewer district and future densities is contingent upon the installation of a lift station and forcemain to bring the sewage to the 21-inch sewer main at Great Plains Boulevard and Lyman Boulevard.The lots within sub-district LB-2 are served by an existing 8-inch diameter sewer that discharges to the Eden Prairie sewer system. Sub-district LB-1 is proposed to have low, large lot and high density residential,office, parks/open space, and office industrial properties.The area encompassed in sub-district LB-3 is currently large lot development with area for future residential low density development. Sub-district LB-5 is primarily undeveloped. There are large lots located on Homestead Lane and Flintlock Trail but there is no sewer service. Eight-inch sanitary sewer would be required to convey the flows from these existing lots and potentially from the proposed lift station in LB-4. The northern portion of LB-5 is proposed for low density and large lot residential,office,and parks/open space. 7.5 I Future Sanitary Sewer System Wastewater Flow Projections Wastewater flow projections were generated for each sanitary sewer district and corresponding sub-districts based on the gross developable acreage available, anticipated land uses, and wastewater flow generation rates. The wastewater flow generation rates for the various land uses found in Section 7 of this report were used to project the future wastewater flows for the service area. "1 The total district existing average and peak flows and also the ultimate 2040 average and peak flows were calculated using the actual development for existing flows and the projected land use for ultimate flows. Estimated peak hour flows are not totaled as the peaking factor is dependent upon the average day flow rate. Summing the projected peak hour flow rates would produce a flow rate higher than the peak hour flow rate for the entire City therefore, the peak hour flows are calculated by multiplying the total average flows by the MCES peaking factor. Table 9.1 below presents the existing and projected 2040 flows for each sanitary sewer district. Figure 7.17 12040 WASTEWATER FLOWS PER SEWER DISTRICT Sanitary Sewer Existing Existing 2040 Average 2040 Peak Hour District Average Day Peak Hour Day Projected Projected Flow Flow(MGD) Flow(MGD) Flow(MGD) (MGD) Minnewashta (MW) 0.150 0.589 0.310 1.126 Bluff Creek (BC) 0.718 2.370 1.017 3.153 Lake Ann (LA) 0.681 2.25 1.114 3.45 Lake Lucy(LC) 0.019 0.074 0.027 0.106 ENorth (NO) 0.316 1.137 0.363 1.308 0 Lotus Lake (LL) 0.595 2.02 0.642 2.18 Lake Riley(LR) 0.222 0.843 0.383 1.377 N Lower Bluff Creek (LB) 0.015 0.061 1.192 3.696 Total System 2.716 7.333 5.051 12.122 t The sum of the existing peak hour flow does not equal the sum of the peak discharges from each district since the peaking factor decreases as the average flow increases. Peaking factors were taken from MCES factors included in Appendix B. 166 Future Trunk Sanitary Sewer System Analysis The 2007 SewerCAD model developed for the analysis of the existing sanitary system flows was utilized to determine the abil- in ity of the existing trunk sanitary system to convey future wastewater flows. Future trunk mains and lift stations will be extended to accommodate future development,which in turn will increase the flows conveyed to the existing trunk system. The trunk sewer system has not been extended since 2007,therefore an updated analyses was not done. Proposed flows were entered into the model and results indicated a reduction in remaining capacity throughout the system, primarily in the Lower Bluff Creek District. Figure 9.1 presents the remaining sewer capacity taking into account proposed future flows. The two sections of the 36-inch trunk main parallel to the MCES interceptor flowing east along the north side of Lake Susan near Highway 101 that exceeded capacity in the existing flow model remained the only two sections exceeding capacity in the future system model. Similar to the existing system model,the MCES interceptor exhibited a few sections exceeding capacity; however, MCES is responsible for monitoring flows and determining deficiencies for this main. The City of Victoria future flows conveyed through the MCES interceptor were not included in the model to analyze future capacities in the MCES Lake Ann interceptor. All existing trunk lift stations with the exception of Lift Station Nos. 7 exhibits adequate pumping capacity to serve future devel- opment. Table 9.2 below shows existing lift station pump capacity and existing peak inflow.

A feasibility report would need to be completed to determine the sewer impacts to the existing lift stations. Typically if development impacts from up zoning are identified upgrades to existing infrastructure are paid for by the devel- oper or land owner(s). Future Trunk Sanitary Sewer System t Minnewashta District(MW) Additional trunk sanitary sewer main improvements will not be necessary to serve the identified future development within the Minnewashta Sewer District.The properties remaining for development are located near trunk and lateral facilities and remain- I ing capacity within the existing facilities is sufficient for estimated peak flows at full build-out. The 2030 Comprehensive Plan addressed the possibility of serving the northeast portion of Victoria through the Minnewashta o District. Subsequently the City of Victoria further examined this service connection and opted to service this area via a future lift station and force main that connect to the Met Council interceptor. 167 L Lift Station No. 7 may need to be increased in capacity in the future.Currently, Lift Station No.28 has a capacity of 100 gpm, with an estimated 25 gpm of existing peak flow. Both of these lift stations would need to the capacity increased if undeveloped • property in Victoria to the west of these lift stations where to development and sanitary sewer service connected to the City of Chanhassen sewer system.The estimated future peak flow from the Victoria development area totals 160 gpm(0.2302 MGD). Bluff Creek District(BC) Improvements to the existing lateral and trunk sanitary sewer system will be required to provide service to currently undevel- oped properties as well as existing properties that do not have City service. Several of the sub-districts will require improve- ments to service the developable areas. Sub-district BC-1: Requires an 8-inch trunk line to service a public/semi-public piece of land with the addition of a lift station to pump the wastewater to BC-4. Sub-district BC-2:Contains a nine acre parcel that can be redeveloped into low density residential with the future installation of an eight inch lateral. Sub-district BC-3:This area is fully developed,however several large lots in the Timberwood development are within this dis- trict and on a septic system;future installation of eight inch lateral sanitary sewer will service these properties. Sub-district BC-4: Potential development of low density residential and public/semi-public land with the future installation of an eight inch lateral. Sub-district BC-5: Fully developed and will not require additional sewer installation. Sub-district BC-6:An 11 acre parcel is the remaining property that can be redeveloped to residential low density. The exten- sion of an eight inch lateral from the existing stub within the southern portion of Fawn Hill Road will service this parcel. Sub-district BC-7:This area is fully developed however several large lots in the Timberwood development are within this dis- trict and on a septic system;future installation of eight inch lateral sanitary sewer will service these properties. Sub-district BC-8:There is one undeveloped office industrial property within sub-district BC-8 that will require an 8-inch sani- tary sewer line to tie into Chaska's system or a new lift station to convey flow to Lift Station No. 24 Sub-district BC-9: Future installation of eight inch lateral sanitary sewer will service the properties on Sunridge Court, Audu- bon Road and Sunset Trail that are currently serviced by septic systems. The vacant land southwest of Lyman Boulevard and Powers Boulevard is guided for medium and high density residential, office and dual guided for commercial pending the extension of eight or ten inch sanitary sewer that flows to Lift Station No. 24. Sub-district BC-10: This area is fully developed as large lot residential. All properties are currently on septic systems. Future improvements include installation of eight inch lateral sanitary sewer and a lift station that connects to the BC-2 system. Lake Ann (LA) Sub-districts LA-1, LA-2, LA-7, LA-8, LA-10 and LA-11 have developed to their full potential and are sufficiently serviced by the existing sewer systems. Subdistrict LA-3. The 19 acre property east of Audubon Road and south of Alisa Lane can be redeveloped into low density residential and serviced by the extension of eight inch lateral sanitary sewer that connects to the system within Alisa Lane and/ r or Stonefield Lane. Sub-district LA-4 also will require an 8-inch line to be extended from Coulter Boulevard to the north to service the future of- • fice-industrial property located west of McGlynn Drive. . Csi Sub-districts LA-5 and LA-6 are proposed to have large areas of development consisting of low,medium,and high density • residential properties. Eight-inch sewer laterals will be needed to convey the wastewater from these sub-districts to the exist- • ing MCES Interceptor. 0 LA-9 is fully developed but there are some low density and large lot properties without sewer service. Eight-inch sanitary sew- • er would be used to connect to the existing sewer system should future connection be asked for by the residents. 168 Lake Lucy(LC) Most of the LC District has sewer service,with the exception of approximately a 10 acre parcel south of Lake Lucy Road at co Yosemite Avenue. Eight-inch laterals were stubbed to the property line when the area to the east developed. North District (NO) The only properties that may be developed in the future are low density residential lots and lie within sub-districts NO-7, NO-8 and NO-9. Additional sanitary sewer trunk lines would not be needed to serve these lots as there are sufficient facilities adja- cent to the properties. Lotus Lake (LL) The majority of this district is fully developed. The potential future developments within sub-district LL-3 and extension of sanitary sewer to existing lots within LL-10 would be served by the existing trunk sanitary sewer system facilities. Eight inch laterals would be needed to accommodate these properties. Lake Riley (LR) Sub-district LR-1 is fully developed with large lots that will require a future eight-inch sanitary sewer and a lift station to pump the wastewater to sub-district LR-2. The proposed sewer would be needed if the residents requested City service, if the area redevelops, or if septic system failures lead to health or safety issues requiring centralized sanitary sewer service. Sub-districts LR-2 and LR-5 are fully developed are sufficiently serviced by the existing sewer systems. Sub-districts LR-3 and LR-4 are mostly developed and contain future low and medium density residential as well as mixed use properties. To serve future development within these sub-districts eight inch laterals are proposed Lower Bluff District(LB) Sub-district LB-1 contains low density residential and large lot properties that will be serviced by eight-inch gravity sanitary sewer. In 2014 the"County Road 61 Corridor Plan" by SRF Consulting Group and Hoisington Koegler Group was finalized and included the trunk sanitary layout and estimated costs. The properties west of the Seminary Fen Scientific and Natural Area(SNA)will require eight sanitary sewer to convey flow to a future lift station at the western edge of the SNA. The remain- der of Sub-District LB-1 will be serviced by eight-inch lateral. A future lift station at Highway 101 and County Road 61 will take all of the flow of LB-1 and pump it north along Highway 101 to LB-5. Sub-district LB-2 is fully developed and is serviced by eight inch sanitary sewer that connects to the City of Eden Prairie. Sub-district LB-3 consists of existing large lot development and future low density residential development. To service this area eight-inch sanitary sewer and lift station just west of Deerbrook Drive will be required. Flow from this area will be dis- charged to LB-5. Sub-district LB-4 is fully developed as residential homes connected to the sanitary sewer via a"201 System". The"201 Pro- gram"instituted by the Metropolitan Waste Control Commission(MWCC)based on Section 201 of the Federal Water Pollution Control Act of 1972. The 201 Facilities Planning identified facilities that were required in order to achieve water quality require- ments. As a result,Carver County led a project in the 1980s to install sanitary sewer along 96th Street to service the existing properties. The project was to correct the existing problems without providing sanitary sewer facilities to accommodate addi- tional growth in the area. The project was paid using federal and local funds;also, benefitting property owners were assessed. eqc When this sewer was installed the services were connected directly to the existing septic tanks instead of abandoning the septic tanks. The old septic tanks are a suspected source on infiltration into the sanitary sewer system. With the proposed sewer layout it may be feasible to abandon Lift Station No.20 and route the flow west to the new lift station located along Powers Boulevard in LB-5. To reduce the amount of infiltration entering the City's sanitary sewer system,when the new sewer g is constructed,services should be installed directly to the homes and all septic tanks should be abandoned. 169 Sub-district LB-5 is primarily undeveloped.There are large lots located on Homestead Lane and Flintlock Trail but there is no "1 g sewer service. To convey the flows from these existing lots and potentially from the proposed lift station in LB-4,eight-inch sanitary sewer would be required. The northern portion of LB-5 is proposed for low and medium density residential and office properties. These properties will require 8-inch trunk mains to carry the wastewater flow. A portion of LB-5 south of Highway 212 and east of Powers Boulevard may be rezoned from low density residential to office. The comprehensive plan assumes the land use will be low density residential as the sewer generation per acre is higher than that of office(822 versus 8700 gpad). The Bluff Creek Golf Course may potentially be redeveloped into low density residential properties. Redevelopment of the Bluff Creek Golf Course may be required to convey the gravity sewer flows from the southern and eastern portions of the LB District. To service the existing properties on Delphinium Lane, Raspberry Hill,and Halla Nursery Drive West,eight-inch sanitary sewer will be needed. To convey the flow from the LB-1 -3 and-5 a 15-inch line will be needed. All of the LB-5 waste- water flows would be taken by gravity sewer to a proposed lift station north of Pioneer Trail and south east of the Highway 212/ Powers Boulevard intersection. This proposed lift station would pump flows to the northeast along the Highway 212 and tie into an existing 21-inch sewer stub in LR-4 of the Lake Riley District. Alternative sewer alignments have been considered to service sub-district LB-3 and the portion of LB-5 south of Pioneer Trail. The alternative alignments, estimated cost(2016 dollars)and design considerations are included in Appendix D. 7.6 Capital Improvement Program Analysis of Area South of Pioneer Boulevard The MUSA expansion area generally lies south of Pioneer Trail. Over the past 10 years two studies have been performed to analyze utility extension to the area:the December, 2014 County Road 61 Corridor Plan by SRF Consulting Group,and the 2016 Kimley Horn Lower Bluff Creek District Sanitary Sewer Study. These studies are intended to serve as guiding documents; actual alignments will be established as development proposals are submitted. These studies are included in Appendix D. The Kimley Horn study included Option 2A,the trunk sewer alignment through the Bluff Creek Golf Course property,and four alternate alignments. Figure 3.4 depicts Option 2A as the future sewer alignment,which is consistent with the previous com- prehensive plan. Table 10.1 includes a summary of only the estimated oversizing cost for trunk sewer and lift station costs to serve the sewer sub-districts south of Pioneer Boulevard. Figure 10.1 in Appendix A details the existing MUSA area and the proposed MUSA expansion area.

The expected service life of the controls and equipment in these lift stations is 20 years. Pumps and motors should —� t be replaced at approximately 33,000 hours of use on an intermittent duty pump station.The City has routinely replaced and up- o graded outdated pumping equipment and controls in many lift stations over the past several years. It is recommended that this v program continue to prevent failure of older and outdated lift station equipment.This replacement program will need to contin- ue over the next 20 years and beyond to keep all the lift stations running efficiently,with minimal maintenance and breakdowns. 170 This replacement program will need to continue over the next 20 years and beyond to keep all the lift stations running effi- ciently,with minimal maintenance and breakdowns.Replacement of outdated pumps and controls in the lift station should be cu `— scheduled as part of the City's capital improvements program.Tables 10.2 and 10.3 present a detailed capital improvement N program in 5-year increments as a proposed schedule for upgrades to the City's lift stations.These tables also include the recommended improvements to be made to each of the lift stations listed.This list of improvements is based on information obtained from City staff and from a site investigation of each lift station. New lift stations that are constructed will need to be incorporated into the lift station capital improvements schedule in the appropriate time period.Table 10.3 presents the cost for the Lift Station Capital Improvements Program per 5-year increment of construction. Most costs include construction costs only and do not include administration,legal,or engineering fees as the work would be completed in-house by City Staff; how- ever, larger projects may need to be outsourced for design.

This table includes trunk system improvements for service areas added, list station improvements, and improvements for I/I reduction efforts. The projected 2040 sanitary sewer trunk system was broken down into improvements based on flow districts. The overall cost associated with these improvements over the next 22 years is approximately$22.5 million. '� 0 These costs based upon 2017 dollars.

Costs are estimated based on 2017 construction costs. , 173 Funding in The City's current sewer fee structure is provided in Appendix E. Fees consist of sewer user fees,trunk sewer fees,and sewer access charges(SAC). Utility usage fees are charged to both residential and non-residential users based on the actual water usage metered during the winter months. The purpose of the user charges is to fund the operation, maintenance, and replacement costs of existing collection systems. User charges are primarily based on the actual costs of operations, maintenance,and replacement of all wastewater system facilities. Trunk and SAC fees provide a funding mechanism for construction of the major infrastructure improvements needed to serve growth. The City of Chanhassen has established that growth should be funded and paid for by those who are in need of the facilities. The development creating the need for additional sanitary sewer system improvements are expected to pay for new trunk facilities and expansion of existing facilities through trunk and SAC fees.Currently,the trunk sewer fees are a per unit cost at the time of development and the SAC fees are calculated based upon the Metropolitan Council's SAC Procedure Manual,which assigns non-residential properties a SAC unit for office or industrial/commercial buildings. Developments and redevelopments that currently are not serviced by the City's sanitary sewer system must construct lat- eral sanitary service to the parcel;the design and installation costs of the lateral sanitary sewer shall be bore by the project developer. Goals and Policies The timing of future trunk sanitary sewer improvements will be influenced by several parameters including development pressures in specific areas,failing on-site septic systems, regulatory requirements,availability of funds,etc. As a result it is difficult to accurately predict the time of future improvements especially those which may occur far into the future. Therefore, the Capital Improvement Program is intended to serve as a guide only for future fiscal planning and should be reviewed on a ...� regular basis as more current planning and cost data becomes available. The following items are general policy guidelines to be considered when reviewing and/or revising the City's fee structure: System Expansion (Orderly Development) Development shall occur in an orderly fashion. Properties that abut parcels served by municipal utilities will be considered as the next feasible property for development. The City may limit development activities to selected areas. Petitions to expand in areas not already under development will be considered. Factors that will be considered include, but are not limited to; capacity in the MCES interceptor,capacity in the City's collection system,economic factors including costs, number of devel- opments under construction and the staff resources available to review the requested development. Leapfrogging Leapfrogging refers to the circumstance where certain parties want to develop an area not currently adjacent to the limits of the City of Chanhassen's existing sewer system. The applicant wants to"leapfrog" over areas located adjacent to the City's existing services that would be the next logical area to be developed. In this circumstance,the City of Chanhassen could decide whether or not to approve such development. If approved, it is recommended that the interested property owner pay for the entire cost of installing services to their property and resulting system upgrades. The developer shall be offered t no credit or reimbursement for these costs. If development of the property that was"leapfrogged" is later initiated, payment aof all trunk charges for the property will still be required regardless of the fact that the facilities were already installed before development occurred. s Overdepth and Oversizing a> The costs of additional depth shall be defined by differences in cost for the depth required by the development and the depth 0 required for trunk facilities. Trunk oversizing as defined by the City and installed by the developer will be credited using the differential of pipe costs between the larger and the minimum pipe size required for the development. Bid pricing shall not be the sole determinate in defining a developer credit. The City shall determine if a credit will be given for a project. 174 Lift Stations Trunk lift stations should be defined as those servicing more than one single development project.The trunk fees will pay c°n' for 100 percent of the cost of trunk lift stations. Lift stations that do not fit the definition for a trunk lift station are to be paid for by the developer. All lift stations shall be designed and constructed in accordance with City standards. The City will consider cost sharing for other lift stations if it is found that a particular lift station may be able to serve a greater area than the single development. The cost sharing shall include the oversizing or overdepth required to serve additional area and associated SCADA system costs to establish the lift station on the City's SCADA system. Existing Developed Unserviced Properties There are a number of existing developed areas that do not receive sewer and water service within the City limits. The trunk system has been designed to handle all existing developed unserviced properties within the City, but it is not the policy of the City to initiate a sewer extension project. If an individual property owner or group of neighboring property owners would like City sanitary sewer services where it is not yet available, the City will review whether or not it is econom- ically viable. Existing developed, unserviced residential properties will be assessed or required to pay connection fees as required by the City Code. Existing Non-Residential Unserviced Properties Existing unserviced commercial/industrial or other non-residential properties wishing to expand or hookup to municipal utilities shall be treated the same as new development and will be assessed or required to pay connection fees as re- quired by the city. 7.7 I Recommendations Based on the results and analysis of this study, it is recommended that the City of Chanhassen and the City Council, where applicable: • Adopt this report as the Comprehensive Sanitary Sewer Plan for the City of Chanhassen. • Review and update the CIP for trunk sanitary sewer facilities every year to reflect sewer improvement projects necessary for the next five year period. » Proceed with future sanitary sewer improvements in accordance with the initial 5-year capital improvement program. Continue to reduce I/I to the existing collection system and maintain provisions for preventing I/I from entering the sanitary sewer system with new construction. d a E 0 SU d N C Ql h h 10 L 175 co APPENDIX A I FIGURES c m E O U 176 L ,Z 1 Existing and Future Sanitary Sewer �%.� and Subdistricts 1--Is -BLS 4-1—FT- L- LS 5 NO 7 �^T� --� LS 21 ! ,t,.L,s 31' LS e' MW 7 { O 11�`.

Only sanitary sewage from approved plumbing fixtures may be discharged into the sanitary sewer system. • No person shall discharge or cause to be discharged, directly or indirectly, any stormwater, surface water, groundwa- ter, roof runoff, subsurface drainage, or cooling water to any sanitary sewer. Any person having a roof drain, sump pump, unauthorized swimming pool discharge, cistern overflow pipe or surface drain connected and/or discharging into the sanitary sewer shall disconnect and remove any piping or system conveying such water to the sanitary sewer system. u All construction involving the installation of clear water sump pits shall include a sump pump with minimum size 11 diameter discharge pipe.The pipe attachment must be a rigid permanent type plumbing such as PVC or ABS plastic pipe with glued fittings, copper or galvanized pipe.All discharge piping shall be installed in accordance with the plumb- ing code. Discharge piping shall start at the sump pit and extend through the exterior of the building and terminate with not less than six inches of exposed pipe. Sump pump discharge location and flow shall be consistent with the approved development drainage plan for the lot.The discharge may not be pumped directly onto any public right-of-way unless approved by the city engineer or his designee. Any disconnects or openings in the sanitary sewer shall be closed and repaired in compliance with applicable codes. » Every person owning improved real estate that discharges into the city's sanitary sewer system shall allow inspection by authorized city employees or its agents of all properties or structures connected to the sanitary sewer system to confirm there is no sump pump or other prohibited discharge into the sanitary sewer system.Any persons refusing to allow their prop- erty to be inspected shall immediately become subject to the surcharge as described in subsection(g)hereinafter. N Any owner of any property found to be in violation of this section shall make the necessary changes to comply with this section and such change shall be verified by authorized city employees or its agents. Any property or structure not inspected or not in compliance by May 1, 1994, shall, following notification from the city, comply within 14 calendar days or be subject to the surcharge as provided in subsection (g) hereinafter. • Upon verified compliance with this section,the city reserves the right to reinspect such property or structure at least annually to confirm continued compliance. Any property found not to be in compliance upon reinspection or any person refusing to allow their property to be reinspected shall, following notification from the city, comply within 14 calendar days or be subject to the surcharge hereinafter provided for. » A surcharge of$100.00 per month is hereby imposed and shall be added to every sewer billing,to property owners who are found not in compliance with this section. The surcharge shall be added every month until the property is verified to be in compliance through the city's inspection program. » The city council, upon recommendation of the city engineer, shall hear and decide requests for temporary waivers from the provisions of this section where strict enforcement would cause a threat to public safety because of circumstanc- es unique to the individual property under consideration. Any request for a temporary waiver shall be submitted to the city g engineer in writing. Upon approval of a temporary waiver from the provisions of this section, the property owner shall agree to pay an additional fee for sanitary sewer services based on the number of gallons discharged into the sanitary sewer system as estimated by the city engineer. u Violation of this section is a misdemeanor and each day that the violation continues is a separately prosecutable offense. `-- The imposition of the surcharge shall not limit the city's authority to prosecute the criminal violations, seek an injunction in district court ordering the person to disconnect the nonconforming connection to the sanitary sewer,or for the city to correct the w", violation and certify the costs of connection as an assessment against the property on which the connection was made.

The water distribution system has been expanded and improved in the last decade since the last comprehensive water plan was completed. Now, the water system can be re-evaluated in light of recent improvements and the need for water system improvements can be re-evaluated. The updated water system model can be used to analyze demands, available supply capacity and storage, and available flow rates and pressures throughout the distribution system. For this purpose, SEH has updated the city's existing water with water main, PRV, treatment and storage improvements that have occurred since the last model update.Additionally,we have processed updated demand data to geo-located water demands in the system so that they are modeled in the area of occurrence. Furthermore, regions of future develop- ment expected to create additional system demands were identified with the help of city staff, along with potential water system improvements that will allow the system to meet these expected demands. The computer model was updated using WaterGEMS v8i.The resulting product is a tool that can be used for hydraulic analysis of the water system, and scenario planning. The model can also be built-upon in the future if so desired to ana- —� lyze water chemistry/water quality throughout the distribution system. In recent years, the city has utilized the model as a valuable tool for: Identification of future locations of critical supply and storage facilities so land can be purchased and/or set aside before development begins in the designated area. u Provide a long range plan for water system upgrades/expansion so that proposed construction projects include properly sized water mains to allow for future development needs. Identify deficiencies in the water system and corresponding improvements to reduce or eliminate these deficiencies. 8.2 Existing Facilities The Chanhassen water system is composed of storage, supply, treatment, and distribution components as described in the following paragraphs. Storage, supply, and treatment facilities are listed in the tables below. 2 a E O U I1 198 Storage Storage facilities on a water system allow a more constant supply during variable demand conditions. During high de- mands, when water customers are using a greater volume of water, part of that demand can be met by storage reserves in addition to direct pumping from wells. During low demand conditions, the well pumps can continue to operate,with excess supply going to fill storage for later withdrawal. In addition to this operational function, storage tanks can serve as an emergency water source in the case of a supply failure(i.e. power outage, well maintenance, etc.), they increase the amount of water available during a fire, and they stabilize water system pressures. Chanhassen currently has four water storage tanks on the distribution system. Three of these are elevated tanks (Melody Hill, Middle School and Arboretum), and one is an above-ground tank(Lake Lucy).All four operate on the distribution system by gravity(without the need for pumping). In addition, there is an underground storage tank(clearwell)at the East Water Treatment Plant with a volume of 200,000 gallons. Water from the clearwell is pumped into the distribution system by the high service pumps at the treatment plant. The existing downtown tank is not currently in use due to the operations problems it creates. Three of the four tanks listed in Table 8.1 provide service to the low pressure zone on the distribution system, and one (Melody Hill) serves the high pressure zone in the northwest part of the distribution system (see Appendix A- Figure 1). The elevation of the overflow weir for gravity-fed tanks on the low pressure zone is 1120 feet. The overflow elevation for the high pressure zone is 1200. This is the highest water level possible in the tanks, and establishes the highest hydraulic grade(pressure) in the system.

Of these 12 wells, seven pump into the East Water Treatment Plant, with the remainder pumping groundwater directly into the distribution system. The treatment plant uses a gravity filtration process to remove iron and manganese from the groundwater. c as U O U 199 43 Of the wells pumping directly into the distribution system, Wells 3, 15, and 9 pump into the main pressure zone, while g Wells 7 and 8 pump into the high zone. These wells will eventually feed the new West water treatment plant. "1 Due to a reduction in capacity, Wells 5 and 6 were deactivated in 2008 and are not included in the well summary. The firm well pumping capacity is that which can be supplied reliably even during maintenance activities or an emergen- cy situation where the largest well pump might be out of service. This figure is often used for design and planning purpos- es, since it represents a worst-case scenario. The total operational supply capacity for Chanhassen is currently 10,600 gpm assuming the well capacities shown in Table 2 while the "firm" supply capacity is 9,350 gpm. The East Water Treatment Plant has a filtration capacity of 6,000 gpm as is noted in Table 8.3.There are 4 high service pumps that draw from the clearwell at the treatment plant,each with a capacity of 2,000 gpm.Therefore,the firm pumping capacity of the plant is 6,000 gpm.

The system has been designed with larger trunk main loops with smaller branch mains. The system serves an elevation range of approximately 850 feet to 1080 feet. Pressures in the distribution system are correlat- ed with elevations, with properties at higher elevations receiving lower pressure and vice-versa. Because services at relatively high elevations have unacceptably low pressures when served by the low pressure zone,a high pressure zone has been created in the northwestern part of the city, east of Lake Minnewashta.This pressure zone is served by separate wells and a storage tank as discussed in the preceding sections. Water from the high zone can also serve demand on the low zone by passing through pressure reducing valves(PRVs) on the distribution system. These PRVs are shown in Appendix A-Figure 1. Under normal conditions, the PRVs between `— the High and low pressure zone remain closed.Additional PRV's are located throughout the system and maintain system pressure to the other low pressure zones. As noted earlier,areas of low land elevation have higher pressures in relation to the existing water storage tanks. When pressures exceed 80-90 psi, it is recommended to reduce these pressures to more usable levels. The Lake Riley, Inter Bluff and Lower bluff pressure zones are all service areas with lower land elevations. These areas have PRV's regulating pressure within the zone. Some of the pressure zones identified for future service have in ground vaults ready for installation of PRVs when additional development requires. Table 8.4 below provides a list of existing system PRV's and their operational status.

They are repre- sentative of temporal variation in water demands. A maximum day peaking factor for a water system is the ratio of the MD demand rate to the AD demand rate. It normal- ly indicates the magnitude of seasonal differences in water demands. For example, if demands on a system increase substantially during the summer due to lawn irrigation, the peaking factors will also be large. Typical MD peaking factors range from 2.0 to 3.0. Larger systems generally have lower maximum day peaking factors. However, predominantly residential municipalities, especially in metropolitan areas, generally have higher peaking factors due to lawn irrigation demands. Recent MD peak- ing factors for Chanhassen are shown in Table 8.6. From the peak demand information that was available, it can be seen that the seasonal demand pattern in Chanhassen is within the typical range. This historical information is useful, not only to assess the capacity of existing water system facilities, but also to anticipate future needs. For future demand projections, a MD peaking factor of 3.1 was assumed in this report, which was the highest of g the previous fifteen years. d C C.)

On an annual basis, the heaviest demand conditions(maxi- mum day demands)occur during the summer, when residential irrigation and other outdoor water use activities increase. Water demands also vary over the course of a given day. Figure 8.2 represents the results of typical hourly demand distri- .. bution graph for total water use in the City of Chanhassen. This was calculated for a typical average day as well as a max- s imum day. For comparison purposes, a typical curve developed by the AWWA for residential water use is also included on ft the graph as a reference. In general commercial and industrial water uses are typically more constrained and predictable. c. All three curves depict low water demand during the early morning periods. It shows increasing demand during the day with a slight decrease in the late morning periods. By late afternoon, demands level off then increase again during the evening hours, likely when residents are home and utilizing more water. As can be seen in the figure, for the peak day c �' co data,the peak hour occurs earlier in the morning,this is likely due to automated irrigation within the City but both commer- 5 cial and residential customers. , g• U 205 at As discussed briefly in Section 8.2, storage reservoirs are used to supplement the supply of treated water during the peak gusage hours within each day. During the early morning periods when demand is low,the system is able to produce water "1 in excess of the demand.This excess is used to fill the storage reservoirs. When the demand rate exceeds the production rate, stored water in the reservoirs is used to make up for the deficit.The storage reservoirs will start to fill when the demand decreases below the total supply capacity.

Storage and supply facilities Ewere modeled based on specifications supplied by City staff. Additional calibration can be conducted in the future, after 0 construction of short-term water system improvements, to improve its accuracy for future use. System Pressure Calculations r Pressures in the future system under average day demands were calculated by the computer model. Due to the elevation g changes in Chanhassen, and the creation of separate pressure zones, the pressures in the system are highly variable. o The model calculates pressures in the range of 40— 110 psi throughout the existing water system. 206 Higher pressures exist on the southern and eastern parts of the distribution system,where elevations are relatively low, with the exception of the reduced pressure zone around Lake Riley. In this zone, the pressure is maintained at a lower level through the use of pressure reduction valves. Industry standard recommends that the normal working pressure in water distribution systems be approximately in the range of 50 to 80 psi, and not less than 35 psi1. In addition, pressures in excess of 100 psi in the distribution system should be replaced by pressure reducing valves. The Minnesota Plumbing Code requires that building plumbing systems not exceed 80 psi. Many of the areas with pressures greater than 100 psi are localized on the system(they are limited to the fringes of the existing distribution system). Expansion of the distribution system to the south will require the use of pressure reducing valves as discussed later in this report. Where pressures exceed 80 psi, individual homes or businesses should install pressure reducing valves on the service line near the entrance to the building, as recommended by the Minnesota Plumb- ing Code. Lake Lucy Road and Powers Boulevard— Analysis of Low Pressures During High Demand Conditions As reported by City staff and mentioned in the previous comprehensive water plan, pressures in the area around the Lake Lucy Reservoir are low during peak demands. This effect is also observed in the computer model.Areas of relatively high elevations are present in the area. Elevations range from about 960 feet in the vicinity of the intersection of Lake Lucy Road and Powers Blvd. to approximately 1040 feet in certain locations. Most of the high elevations are found on the south and east side of the intersection. It appears from the computer modeling results that there are about 50 homes that may drop below 35 psi during high de- mands when levels in the Lake Lucy Reservoir are low. If levels in the reservoir drop to 50%of capacity that corresponds to a water elevation of 1105 feet(15 feet below overflow). At this level, any water service above an elevation of about 1024 feet would drop below 35 psi. As stated previously, industry standard recommends that pressures remain about 35 psi under normal operating conditions,which includes periods of relatively high demand. Since this is primarily an elevation issue, distribution system replacements or upgrades are not expected to have a signif- icant effect in improving pressures in the area. The following three options are presented here for dealing with this pres- sure issue: Do nothing. The pressures do not appear to be critically low, and residents have adapted to conditions as they are. Install individual booster pumps on homes that require higher pressure. Create a small boosted pressure zone. A small booster station operating on a closed system is possible in the area. The city would need to conduct a detailed study of the issue to determine the optimal way to create such a system while maintaining circulation in the water system to prevent stagnation and the creation of dead ends that would limit d fire protection capabilities. p c. U c I r O 207 ti Pressure Zone Analysis 5 As part of the comprehensive water plan update,the establishment of the pressure zone boundaries was re-visited. Since the last comprehensive water plan was completed, pressure reducing valves/vaults have been installed as the system has expanded,which in turn define the boundaries of the pressure zones.As the system evolves, it is generally a good idea to revisit the pressure zone development,identify potential changes and review improvements so the ultimate system provided is optimized. For example,the pre- vious plan identified potential options for definition of the pressure zones. Now that new water main has been installed, and pressure reducing valve vaults have been placed,this boundary had changed slightly.As part of this update, a system wide contour map was updated to show parcels of land that can be served by the various pressure zones(see Appendix A-Figure Al). The High and Low pressure zones are defined by the elevated water storage tanks that exist in these zones,with HGL's of 1200'and 1120' respectively, these tanks maintain pressures of 40-80 psi to the majority of the service areas. The boundary of the High pressure zone has been clearly defined and does not have a very high potential to be changed or modified in the future.The Low/Main pressure zone, which is essentially the default pressure zone for the majority of the system, serves the remaining areas with the exception of the Lake Riley Pressure zone which is essentially a reduced pressure zone, served by PRVs from the main zone. In the past, this type of pressure zone had issues with large changes in flow. For example,when hydrants are flowed in this zone, and shut off, pressure tends to bounce and transients are not very easily dissipated. This head resulted in water main breaks and water heater failure in some homes. In general, closed water pressure zones(without elevated storage or a standpipe) can experience difficulty with major flow changes as water is not compressible.When a valve is suddenly shut off(or A PRV throttled back), the water flowing in a corresponding pipe is suddenly forced to stop. Because of this, high pressure builds up immediately behind the shut off valve and low pressure forms in front of it.The momentum of the water is suddenly transferred into the physical sys- tem piping. As a result, a high-pressure region of water"piles up" in the pipe.This high pressure region then travels back along the pipe in the form of a wave. The border of the high-pressure zone is referred to as a pressure wave, or transient. Such a pressure wave only exists for a short period of time but can cause damage to piping and fittings.Transients are not very well understood and are not always accounted for in the design of a water distribution system. A previous comprehensive water plan identified five potential alternate water pressure zones, with two of the zones(Lake Riley and Interbluff) having similar hydraulic grade lines. In light of recent development, and construction of new PRV facilities, a new pressure zone configuration was developed.The primary goal of the pressures zone restructuring was to sustain ideal pressures at all service elevations, simplify zone configurations, and reduce the number of PRV's required to sustain pressure. d a_ 0 U qyN 10 � 10 208 Available Fire Flow Available fire flows were calculated using the computer model with a residual pressure of 20 psi.According to the American Water Works Association(AWWA),the minimum fire flow available at any given point in a system should not be less than 500 gpm at a resid- ual pressure of 20 psi.This minimum criterion represents the amount of water required to provide for two standard hose streams on a fire in a typical residential area for residential dwellings with spacing greater than 100 feet.The distance between buildings and the corresponding recommended fire flow for residential areas is summarized in Table 8.8. Table 8.8 I TYPICAL FIRE FLOW REQUIREMENTS Building Available fire Separation flow @ 20 psi Land Use (feet) (gpm) Single & Two Family Residential >100 500 Single & Two Family Residential 30-100 750 Single & Two Family Residential 11-30 1000 Single & Two Family Residential <10 1500 Multiple Family Residential Complexes - 2,000 to 3,000+ Average Density Commercial - 1,500 to 2,500+ High Value Commercial - 2,500 to 3,500+ Light Industrial - 2,000 to 3,500 Heavy Industrial - 2,500 to 3,500+ Source:Insurance Services Office For commercial and industrial buildings, the needed fire flow rate varies considerably, and is based on several character- istics of individual buildings such as: » Type of construction » Type of business that is using the property(occupancy) » Proximity and characteristics of nearby properties » Presence or absence of a fire sprinkling system While the fire flow requirements of commercial and industrial properties should be evaluated on a case-by-case basis, a general rule of thumb is that a municipal water system should aim to provide 3500 gpm to this type of land use.The Insur- ance Services Office(ISO), in determining a City's fire insurance classification, only considers flow rates up to 3500 gpm. Available fire flows throughout the Chanhassen water system are highly variable, due primarily to topographical changes. . Available flow rates in the model range from about 500 gpm in some locations to greater than 5000 gpm in others.Areas of t potential concern include commercial, industrial, or high-density residential land uses where the available flow rate at the water main is less than 3500 gpm.The previous comprehensive water plan identified three distinct locations that had less than desirable available fire flow, as calculated by the water model.Since the previous evaluation, improvements to the water system, including a new water tower have strengthened the water system, subsequently, the areas of concern in rela- tion to limited fire flow have been remedied. In short, major fire flow deficiencies were not identified as part of this analysis. I However, this evaluation is not intended as a comprehensive building by building fire flow analysis, rather a comparison of t computer modeling results with land uses across the existing water distribution system. U 209 8.7 I Projected Water Demands -� >' Future sales and pumpage projections can be based on assumptions of water demands that can be expected according to future land use or population data.Two different means for water use demand projections and are documented and compared below. Projected Water Demands - By Projected Population Previously in this report, per capita average day water use was calculated.Maximum of this figure for the past 5 years was found to be 139 gallons per day per person.This figure was then multiplied by projected population data.The resulting projected water average and max day demand data is shown below in table 8.9.

In addition to normal water uses, system facilities are often sized for fire protection needs, including additional storage facilities ex.water 5 tanks and supply. t Facilities(wells and a future West water treatment plant), and water mains to expand and improve water delivery.The follow- ing sections of this report discuss the estimated need for future water system facilities, based on the demand projections presented in Table 8.11. C d r Future Distribution System -� In Appendix A-Figure 7,a proposed trunk water main layout has been drawn as part of the future water system vision,the future 'S mains include 12-inch loops helping to balance the future water system by allowing large volumes of water to flow between supply, 0 storage,and points of use.These trunk main loops will be required to effectively transport water to the extremities of the proposed expansion areas. Looping is recommended wherever possible to minimize dead-ends in the water system. 212 Dead-ends,or branched water systems are less reliable since water must come from one direction.This forces the utility to shut off water to some customers during repairs or maintenance. In addition, larger head losses(or pressure losses)are experienced on �- dead-ends than on looped systems.This can limit available flow rates during fire protection activities. In addition to future system improvements,the existing system could be improved by eliminating dead ends that are relatively long or less than 8 inches in diameter.This work should be coordinated with future street replacement projects to reduce costs where possible. Due to the fact that much of the future service area on the south end of the City already contains residential development, it is difficult to provide trunk main looping to serve the proposed developments on the far south end of the future service area, such as those pro- posed between the Hennepin County Regional Trail Corridor and Flying Cloud Drive.The proposed distribution system serves these developments using long dead end mains for this reason. If possible,the City should consider looping these segments to improve system hydraulics.A connection may be possible on the east- ern extent of the future main shown on Hying Cloud Drive to the proposed 12-inch main on Deerbrook Drive. Pressure Zones The Chanhassen water distribution system serves a range of elevations that prevents the entire system from being served on a single pressure zone. In order to keep pressures at acceptable levels throughout the system,there are currently three separate pressure zones in the system.The pressure zones are defined by different hydraulic grade,which allows pressures to remain in a more accept- able range.The pressure zone boundaries are shown on Appendix A-Figure 2. As part of the water comprehensive plan update, a review of the pressure zone boundaries was completed by analyzing citywide land elevations with resulting reasonable pressures within each defined pressure zone.The result of this analysis is shown in appendix A. In short,the current pressure zone plan could be optimized to simplify operations.The map shown in figure Al is defined to show which pressure zone would be best suited to serve varying land elevations. In those areas that may have sops that fall out of toler- ance, individual PRV's could be installed if the water pressure in the street exceeds 80 psi. The largest zone is the Low Pressure Zone,which is currently served by the East Water Treatment Plant;Wells 3,4, and 9;and the Lake Lucy and Arboretum storage tanks.The hydraulic grade of this zone is determined by an overflow elevation of 1120 feet for the storage tanks. The High Pressure Zone is located roughly between Hazeltine Blvd.and Galpin Blvd., north of Arboretum Blvd.This zone is currently served by Wells 7 and 8, and an elevated storage tank, Melody Hill,which has an overflow elevation of 1200 feet. Future developments on the south end of town are at relatively low elevation compared with the rest of the city.As the distribution system expands into this area,the water pressure in the mains will need to be reduced through the use of pressure reducing valves, similar to the way in which the Lake Riley Pressure Zone is currently served. Future developments on the south end of town are at relatively low elevation compared with the rest of the city. As the distribution system expands into this area, the water pressure in the mains will need to be reduced through the use of pressure reducing valves, similar to the way in which the Lake Riley Pressure Zone is currently served. In light of recent development, and construction of new PRV facilities, a new pressure zone configuration was developed. The primary goal of the pressures zone restructuring was to sustain ideal pressures at all service elevations, simplify zone configurations, and reduce the number of PRV's required. In the future, it appears that the existing Lake Riley pressure zone could be merged with the Interbluff pressure zone and served but a single elevated storage tank. Not only would this simplify system operations, and reduce the reliance on PRV stations, but pressures in these zones would be sustained by a storage vessel which would ease pressure transients and 04 better serve major changes in flow, reducing the possibility of pressure spikes. Appendix A-Figure 7, represents a poten- tial location for an elevated storage tank for the new combined Interbluff/Lake Riley pressure zone. 0 213 to Future Supply Facilities Firm supply capacity, which is the amount of water that can be reliably supplied with the largest well out of service, should be greater than or equal to the maximum day demand.When projected maximum day demands reach firm capacity, it is an indication that additional water supply capacity is needed. The projected 2040 maximum day demand for Chanhassen is approximately 11,120(16.0 MGD) gpm. As mentioned in previous studies, the City should plan to serve the maximum day demand with firm capacity, defined here as the supply capacity with the largest distribution system well out of service and the largest well supplying the East Water Treatment Plant out of service. The total system capacity with Wells 2, 3, 4, 7, 8, 9, 10, 12, 13 and 14 will be 8,850 gpm.The firm capacity will be 7,450 gpm. To meet ultimate demand projections, there will be a well capacity need of approximately 3,700(11,120 gpm- 7,450). Based on previous well capacities, that will equate to four additional future wells to meet projected maximum day demands. It is suggested that three additional wells serve the future West water plan while one additional well should be constructed to serve the east water treatment plant.

For many communities, fire protection needs tend to be the controlling factor when calculating needed storage volume.Table 8.13 shows the calculations used to determine future water storage volume requirements for the total system in Chanhassen.These calculations consider ultimate development of the proposed expansion areas. r Water storage facilities should be able to supply the desired rate of fire flow for the required length of time during peak demands, when the water system is already impacted by other uses, and with the largest pump out of service. The calcu- Elations in Table 8.13 assume that 75%of storage volume is available for firefighting, maximum day demands are occurring 5 on the system, and the well with the greatest capacity is out of service. g It appears, based on the demand projections used here, that Chanhassen will need about 1.0 million gallons of future 0 additional storage for the system as a whole. 0 U 214 There is a trade-off between storage volume for fire protection and water quality. If the storage volume becomes too much m greater than average day demands, it can result in longer tank residence times and increased water age. With age, water I �-- can lose its chlorine residual and develop taste and odor problems as well as a potential for bacterial contamination. Previously, 750,000 gallons of elevated storage was recommended for the high zone. Since this recommendation was made,the new 750,000 gallon tank has been constructed. With this tank in place, the projected additional storage need for the water system as a whole is around 1.0MG, which could be constructed in the main zone or as discussed later, in the proposed combine Interbluff zone. Proposed locations for the future 1.0 MG tank is shown in Appendix A-Figure 7.

Elevated Storage) (gal) Additional Storage Required (gallons) (1,630,000) 200,000 900,000 Assumes Supply Remains Constant 8.8 I Analysis of the Proposed System Layout The computer model of the distribution system was used to calculate pressures and available fire flows as was done previously for the existing system. Much of the new development is expected to the south of the existing water system, where elevations decrease as discussed in previously sections. When PRVs are set in the model to correspond to the recommended hydraulic grades, and are located as shown in Appendix A-Figure 7, pressures and available flows for fire protection appear to be adequate to support the proposed land uses, based on the criteria presented in Section 8.4. Extended Period Stimulation As part of the previous comprehensive plan,an extended period simulation(EPS)was conducted using the model to analyze • system operations during several days of maximum day demands.The primary purpose of this simulation was to check for cumulative system imbalances that are not evident in standard simulations and to verily if system operations can be main- tained under high demand conditions. The locations of supply and storage facilities, and the sizes of distribution system pipes, contribute to imbalances. Con- siderable distances between supply and storage locations and inadequately-sized water mains can contribute to a reduced storage-replenishment rate and the ability to refill the towers at night during low demand periods. � t U 0 U 215 a, Once again, we have conducted a 72-hour water model simulation to review the possible water tower site A location.We have simulated a 72-hour period with three consecutive maximum day(MD) demand conditions.This time period was chosen since most supply and distribution system deficiencies will be exposed in three days of operations with MD de- mands. For example, if tanks are unable to refill daily under high demand conditions, a trend will emerge in tank level data produced by the EPS. The model was simulated with a new tank located at site A, feeding the combined Interbluff/Lake Riley zone.The simula- tion found that it is feasible to sustain water system pressures with this type of configuration. The existing main pressure zone tanks operate and float at similar weathers while the proposed tank sustains more consistent pressures in the lower pressure zone. 8.9 I Conclusions and Recommendations Supply Environments Firm supply capacity(the supply capacity with the largest pump out of service) should be greater than maximum day de- mands. The city is currently in the midst of constructing the West Water Treatment Plant, which is estimated to have a ca- pacity equal to the recently constructed East Water Treatment Plant(6,000 gpm). In order to fully utilize these two plants, it is estimated that four new wells will be necessary during the life of this plan to meet projected water demands based on projected development in the city. Distribution System Improvements Trunk main looping should be a priority in the expansion of the service area and in water main replacement projects. The proposed layout of trunk water mains in this report would provide water supply and fire protection capabilities to existing '"1 and projected service areas. In addition, recommended trunk mains will connect water supply and storage facilities with points of use on the system. The city can also work towards the eventual combination of the Lake Riley and Interbluff pressure zones, which may be the most ideal location for a new elevated storage tank. Storage Improvments The volume of water storage needed in Chanhassen is dictated by daily demands as well as fire protection. Currently, storage capacity is meeting system needs. Projected demands will create a need for one additional 1.0 MG elevated water storage tank over the life of this plan. A new concept, which places a new tank in the combined Lake Riley/Interbluff lower pressure zone which will help supply these pressure zones with water as well as stabilize system pressures. Report and Model Update This report should be reviewed on an annual basis. Changes in development type or densities can have significant impacts on a water system's performance, especially during drought conditions or emergencies such as fires.A report 2 update should be planned for approximately 5 to 10 years dependent on development pressure. a 1 The water system model produced as part of this project is a valuable tool in assisting with design and construction of g Chanhassen water system components. It can be easily updated on an annual basis and used to evaluate the impacts of s proposed developments or project phasing. A copy of the computer model will be provided to the city. 0 216 APPENDIX A N N L CQ.

Surface Water The Local Water Management Plan(LWMP)was prepared in conformance with Minnesota Statutes 103B.235 and Minnesota Rules 8410. This plan is intended to provide the City of Chanhassen with information and direction in the administration and implementation of water resource management activities within the city during the period 2018-2027. It serves as a guide to projects, provides for effective allocation of resources, and sets forth a funding plan for projects and programs over the next 5 to 10 years. The city will adopt by reference the local 2018-2027 surface water management plan (LWMP)and will incorporate the six water resource goals as specified in the LWMP. Goals 1. Promote abstraction through infiltration, reuse and other methods where practicable to do so to provide flood protection, ground water recharge and improved water quality. 2. Achieve water quality standards in lakes, streams, and wetlands consistent with their designated uses and established classifications. 3. Protect and rehabilitate wetlands to maintain or improve their function and value. 4. Prevent contamination of the aquifers and promote groundwater recharge to maintain base flows in streams and wetlands. 5. Maintain primary responsibility for managing water resources at the local level where efficient to do so but continue coordination and cooperation with other agencies and organizations. 6. Provide information and educational resources to improve knowledge and promote an active public role in management of water resources. 42 m E ChapterlO E . Q 0 ys: (--, . ..
