BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM TO: Planning Commission FROM: Bob Generous, Senior Planner DATE: October 8, 1997 SUBJ: Comprehensive Plan Transportation, Public Sewer and Water Elements BACKGROUND The transportation and public sewer and water elements of the comprehensive plan are the fifth and sixth elements of the comprehensive plan that will be examined. These elements deal with infrastructure improvements that create a vital and healthy community by providing the skeleton upon which development depends, that assist in the implementation of city goals and policies contained in the comprehensive plan, and that provide a guide for the orderly expansion of city services and efficient investment of public capital. One of the biggest opportunities and requirements of updating and revising the comprehensive plan is in response to the Metropolitan Council's Growth Strategies. The City must determine, through its Metropolitan Urban Service Area (MUSA) expansion plan, the timing and direction of growth in the community. A second issue is to develop a policy to determine how and when public services will be provided to rural type developments. While the city currently has a policy regarding extension of services in the case of failing systems, another issue relates to instances where it is feasible to extend services, but when it may not be appropriate. A third major issue that needs to be addressed is whether the city should develop specific level of service (LOS) standards for roadways. These standards could stop or limit growth based on adequacy of roadway capacities, or redirect growth to areas that may not be appropriate for urban type development, but have excess capacity. In addition, should the LOS standards be different for city, county, and state roadways or be based on functional classification? Planning Commission October 8, 1997 Page 2 A fourth issue is to determine whether the city should expand policies to emphasize multi-modal transportation including mass transit, bicycle and pedestrian facilities, and transportation demand strategies. ANALYSIS TRANSPORTATION As of January, 1997, the city had 135 miles of roadway of which 90 miles were local roads. Since 1991, many of the projects and system deficiencies outlined in the transportation element have been completed or are under construction: 1. Crosstown Highway 62 to Town Line Road 2. Intersection improvements at Highways 101 and 5 3. Highway 5 four-lane to west of Powers Boulevard 4. Realigned W. 78th Street 5. Galpin Boulevard widening south of Highway 5 6. Lake Ann Park entrance 7. Highways 101 and 169/212 signalized 8. East-West connections between Galpin and Highway 41 (Longacres Drive and Lake Lucy Road) 9. Coulter Boulevard between Audubon Road and Galpin Boulevard 10. Lake Drive between Dell Road and Highway 101 11. Minnewashta Parkway However, some very significant improvements have not be completed, or for that matter, started: 1. Highway 101 widening and realignment. 2. Highway 212 3. Highway 5 west of Powers Boulevard and the north access boulevard 4. Powers Boulevard(CSAH 17) extension between Lyman Boulevard and Pioneer Trail 5. Pleasant View Road The city has undertaken, in conjunction with Carver County, an update of the Eastern Carver County Transportation Study which was last done in 1990. This study looks at traffic forecasts and system requirements throughout the community. It is anticipated that the forecasts will be completed by the end of 1997, but that the system requirements won't be done until June 1998. However, based on traffic forecasts, the city can estimate local roadway improvements that will be necessary to keep traffic flowing. Planning Commission October 8, 1997 Page 3 LOS standards represent a capacity analysis or quantitative measure of flow through an intersection or along a roadway segment. The basic output from a capacity analysis is an LOS letter grade (A-F)with LOS A representing minimal delays and no congestion,and LOS F representing substantial delays and congestion. LOS E is considered the actual capacity of an intersection or a traffic movement. LOS D is, generally, considered to be an acceptable level of traffic operation in urbanized areas during peak traffic hours. LOS E and F are common during peak hour conditions in urbanized areas for left-turn movements at unsignalized intersections. Based on the functional classification of a roadway and jurisdictional responsibility, the city has different levels of control over the impacts to the road system. For arterial roadways which provide inter-community travel, the city has little control of the LOS standards that will be maintained, e.g., Highway 5 and 41 intersection will reach LOS F by 2002 with or without any development within the city taking place in this area. For local roads,the city has substantial control of development impacts. LOS standards are a two edged sword. While high LOS standards maintain and enhance quality of life, these standards could stop or limit growth based on adequacy of roadway capacities, or redirect growth to areas that may not be appropriate for urban type development, but have excess capacity. A discussion item could be that the city will permit development that may reduce LOS standards on abutting roadways if the development includes, as part of the project, significant trail or sidewalk systems tied into community trails or if the development incorporates transit facilities. Transit is becoming more and more critical in planning a community's transportation system. The City of Chanhassen in conjunction with Chaska and Eden Prairie are members of the Southwest Metro Transit Commission. Southwest Transit is an"opt-out"agency operated under a joint powers agreement between the three cities. Southwest Transit provides express, tele-bus, circulator, reverse commute, and special services to member communities. As the community continues to grow the transportation system will continue to be impacted. With fewer and fewer state and federal funds available for roadway construction, the city will need to rely on other forms of transportation to meet the needs of residents and businesses in the community. Staff will be looking at strengthening policies related to mass transit as part of the update. As part of the update of the plan, the background section for transportation will be streamlined based on the following outline: I. Introduction. II. Inventory of existing system. III. Proposed System IV. Mass Transit V. Bicycle and Pedestrian System Planning Commission October 8, 1997 Page 4 UTILITIES In 1993,the city completed a Comprehensive Sewer Policy Plan and Water Supply and Distribution System Plan which looked at the provision of public sewer and water throughout the community. These plans are incorporated in the comprehensive plan and will be used in developing MUSA expansion plans as well as capital improvement plans. The city has approximately 100 miles of sanitary sewer and water main lines as of January 1997. Seven of an estimated total of 18 wells and pump houses have been built. Significant utility expansion projects completed since the 1991 plan include the Bluff Creek trunk lines, the Lyman Boulevard/Lake Riley area utility expansion, and the completion of the Lake Ann interceptor. A significant problem for the sanitary sewer system has been infiltration and inflow in the sewer lines. In 1997, the city initiated a sump pump inspection program to look at clear water being pumped into the sanitary system. In addition,the city has redeveloped the downtown area replacing the sanitary sewer system and creating a storm water management system that reduces inflow in the area. The city has also developed policies requiring new subdivisions to provide drain tile behind curbs for sump pump discharges. The city has several neighborhoods that are developed as large lot residential projects,both inside and outside the MUSA area. Staff is proposing that a policy be added to the comprehensive plan that would only permit large lot development to connect to public system if a majority of the property owners in the development agreed to connect to the system. One of the requirements of updating and revising the comprehensive plan is in response to the Metropolitan Council's Growth Strategies. The City must determine,through its Metropolitan Urban Service Area (MUSA) expansion plan, the timing and direction of growth in the community. As a point of beginning, staff has prepared a draft MUSA expansion plan based on projected absorption rates and capital expenditures. 2000 MUSA - Existing MUSA established in 1991 2003 MUSA- Incorporates all the areas north of Lyman Boulevard that are currently excluded from the MUSA. However, staff would propose that exemptions be made for the Minnesota Landscape Arboretum, Camp Tanadoona, and Lake Minnewashta Regional Park. 2008 MUSA-Incorporates the land northwest of proposed T.H. 212 between Lyman Boulevard and Pioneer Trail, and the balance of sewer area LR-2. 2013 MUSA - Incorporates land between Lyman Boulevard and south line of Sections 25 and 26 and Bluff Creek Drive, southeast of T.H. 212 and west of Highway 101. Planning Commission October 8, 1997 Page 5 2020 MUSA - Incorporates the balance of the community. In developing this plan,the following issues need to be addressed: • What happens to land prices? Is the expansion line too restrictive? How many years of capacity should be incorporated in MUSA expansion plans? • What happens if someone refuses or does not want to develop their land? • What happens if development exceeds projections? Should the city slow down development or build in mechanism for MUSA expansion prior to estimated years? • Flexibility must be built into the system to permit the city to respond to changing opportunities. As part of the update of the plan, the background section for the utilities section will be streamlined based on the following outline: I. Introduction. II. Inventory of existing system. III. Proposed System REVIEW GOALS AND POLICIES UTILITIES GOAL Provide public sanitary sewer,water, storm water, electrical, natural gas and communication service to all urban density residential developments and all non-residential, commercial and industrial uses in a manner which is responsive to natural resource protection concerns within the City. • This goal is still appropriate, however, it should be expanded to incorporate the idea that service will be provided in a planned and efficient manner. Eventually, it is envisioned that the entire city will be serviced by public facilities. In response to the Metropolitan Council Growth Strategy, the City will develop and adopt a MUSA expansion schedule. Planning Commission October 8, 1997 Page 6 POLICIES It shall be the responsibility of the City Engineer and Planner to give technical advice and aid to the Planning Commission in preparation of necessary utility plans. * This policy is still appropriate. City staff provide technical review and advice on all utility plans. Formulation of utility plans shall be coordinated with city plans for land use, transportation, open space and community facilities as described in the Chanhassen Comprehensive Plan. Wherever practical, utility plans should be coordinated with the Park and Recreation Commission's plans for linear open space and passive play areas. * This policy is still appropriate. Formulation of local plans for utilities shall be consistent with the plans and procedures of the Metropolitan Waste Control Commission(MWCC)which accommodate the future growth and continued vitality of the City of Chanhassen. * This policy is still appropriate and required. The Metropolitan Waste Commission has been replaced by Metropolitan Council Environmental Services. To plan and provide an efficient local sewage collection system to transport sewage to appropriate metropolitan facilities. * This policy is still appropriate and should be expanded to include the development of a MUSA expansion plan and growth strategies plan. Ensure that local sewer investments are coordinated with metropolitan sewer system plans. * This policy is still appropriate. Utility systems within the City of Chanhassen should be based upon: 1. Maximum protection of health and safety; 2. Adequate and efficient service; 3. Fair and equitable distribution of benefits and costs. * This condition is still appropriate. A fourth element should be added that states that utility systems will be coordinated with the installation of other public infrastructure improvements. Planning Commission October 8, 1997 Page 7 All utility systems should be installed in newly developing areas before or at the time of development. This allows for more economical utility installation, reduction of damage to streets, less erosion and a reduction of public improvement installation costs. * This policy is still appropriate. However, the policy should be mandatory(shall), rather than prescriptive(should). All public and private utilities within the city should be installed in a coordinated manner and in accordance with the sequencing and level of service indicated in the Chanhassen Comprehensive Plan. * This policy is still appropriate. This policy is directly related to the MUSA expansion plan and the capital improvement element. Maintain, operate and reconstruct where necessary, the existing utility systems so that they can ^onto support existing development and redevelopment in the urban service area. * This policy is still appropriate. Staff believes the condition should be modified as shown. Establish an ongoing system of inspection and monitoring of local sewer, storm and water systems. * This policy is still appropriate. The city currently televises portions of the sewer system annually, takes water samples weekly, and inspects stormwater systems as needed. The direct discharge of untreated domestic or industrial waste into any water body, water course, or drainageway shall be prohibited. * This policy is still appropriate. Roof water and paved surface drainage shall be channeled into a storm water system as approved by the Chanhassen City Engineer and appropriate regulatory agencies. * This policy is still appropriate. Storm water run-off shall be held on the land for the greatest extent possible. * This policy is still appropriate. All urban density development shall be served by comprehensively designed storm water drainage systems. Natural drainageways, streams, and ponding and other holding areas for Planning Commission October 8, 1997 Page 8 surface water run-off should be publicly preserved. Gutters, catch basins, and storm sewers should conduct surface water run-off to the natural drainageways and away from building areas. * This policy is still appropriate. It should be modified to incorporate that drainage systems shall be consistent with and implement the city's storm water management plan(SWMP). Utilities such as cable, electricity,telephone and natural gas must be available at the time any development is open for occupancy. Whenever possible,those services shall be underground. All underground utilities should be installed at the same time to reduce installation and maintenance costs. Where overhead utility lines are necessary, their design and alignment should be compatible with existing,proposed or probable development of the area. * This policy is still appropriate. Staff recommends that the protection of natural resources should be added as part of this policy. Any structure to be inhabited should provide the following: - A continuous supply of potable water. - Sanitary facilities and an approved sewage disposal system. - Heating adequate for healthful and comfortable living conditions. - Hot water for domestic use. - Electricity for lighting and equipment use in the dwelling. - Within the urban service area,water service and hydrant outlets shall be provided for fire protection. The spacing and design criteria of these systems shall conform to city ordinance and shall serve to improve or maintain the existing fire insurance rating. * This policy is still appropriate. GOAL To provide for reasonable and environmentally safe development at low densities experienced in areas located outside the MUSA line consistent with the City's land use goals and policies. * This goal is still appropriate since much of the city will remain outside the MUSA boundary for the foreseeable future. Planning Commission October 8, 1997 Page 9 POLICIES The city will establish an ongoing inspection system and permit issuance program for septic systems consistent with the guidelines and regulations stated in the local sewer plan. * This policy is still appropriate. The city is in the process of developing the program. It is anticipated that it will be implemented in the summer of 1998. The Chanhassen sewer plan will indicate acceptable locations, ordinances and design standards for septic tank systems. * This policy is still appropriate. City ordinances are in place to implement this. The city shall provide informational assistance to septic tank users on how to maintain and operate on-site disposal systems. * This policy is still appropriate. Building Department staff provide informational assistance. The pumping of sludge from septic tank systems will be discharged into the metropolitan disposal system only in such locations as may be designed by the city and the MWCC. * This condition is still appropriate. The initials shall be amended to MCES. The city shall forbid sewered urban-type development in designated rural service areas which lie adjacent to existing or proposed sewer interceptors. * This policy is still appropriate. It is related to a proposed policy regarding how rural type development will be allowed to be serviced by public facilities. Non-urban land uses should be served by properly constructed and operated septic tank and well water systems. * This policy is still appropriate. — GOAL To recognize the often unique circumstances of unserviced lots located both inside and outside of the MUSA line located in subdivisions that were platted prior to 1987 under ordinances that allowed down to 2 %2 acre lots minimums. Planning Commission October 8, 1997 Page 10 * This goal is still appropriate. Many people have"bought into"the rural type neighborhoods. Staff is proposing the adoption of a policy that addresses how and when these developments may be serviced. POLICIES These lots were, for the most part,developed relatively recently and have new on-site sanitary and water service built to high standards. The City will, therefore, seek to ensure that these subdivisions are not unduly burdened by new local utility lines and related assessments. The City Council should seek to adopt sensitive policies for trunk line improvements as well. * This policy is still appropriate. The City will utilize policies listed above to ensure the proper maintenance and functioning of these systems. Property owners must understand that proper maintenance and upkeep of on-site systems is their responsibility. At such time as on-site systems begin to fail the City will work with residents to install utilities to these subdivisions in a coordinated, comprehensive manner. Since onsite systems tend to fail at different times at different lots in a subdivision, residents should be aware that utilities may need to be provided before a consensus is achieved from all impacted property owners. Homes developed since 1987 in the Rural Area are equipped with alternate drainfield sites. If problems occur with the primary site, the City would look favorably on allowing use of the secondary site if it is still functional. * This policy still applies. TRANSPORTATION GOAL Create a multi-modal transportation system which permits the safe, efficient and effective movement of people and goods. * This goal is still appropriate. POLICIES Provide a local transportation system which is consistent with the plans and programs of the County,Metropolitan and State systems as well as with the overall growth policies of the City of Chanhassen. * This policy is still appropriate. Planning Commission October 8, 1997 Page 11 Transportation facilities should be planned and designed to be compatible with the surrounding environment. * This policy is still appropriate. Encourage multiple use of right-of-way areas accommodating various modes of transportation. * This policy is still appropriate. Thoroughfares and major routes should be planned so as to reduce conflicts between external traffic and local traffic while minimizing the disruption or division of the logical pattern of development in the community. * This policy is still appropriate. Combine streets,highways, mass transit, terminals, and parking facilities into a coordinated transportation system. * This policy is still appropriate. However,pedestrian and bicycle access should also be incorporated in the policy. Provide flexibility for additions or modifications to the transportation system by basing right-of-way requirements on an evaluation of future transportation needs. * This policy is still appropriate. 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. It will also be amended from time to time by the City during the subdivision review process. * This policy is still appropriate. 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 connections to maximize safety and ease of access. * This policy is still appropriate. Staff is recommending that pedestrian connections also be incorporated in this policy. Planning Commission October 8, 1997 Page 12 Neighborhoods should be planned and designed to limit or discourage external trips traversing the neighborhood. * This policy is still appropriate, and is also addressed through the city's Land Use designations. Sufficient setbacks and/or berming should be designed into all development projects adjacent to major public roadways. * This policy is still appropriate. 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. * This policy is still appropriate. Promote increased development of bikeways and trail facilities in order to conserve energy resources, enhance recreational opportunities and assist in the abatement of pollution and congestion. * This policy is still appropriate. Promote safe and convenient access connections between the highway system and major commercial areas, industrial uses, and residential neighborhoods. * This policy is still appropriate. The City should cooperate with the Regional Transit Board and Southwest Metro 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 encourage transit use. * This policy is still appropriate. However,the RTB is now the Metropolitan Council. In major areas of employment and commercial activity, sufficient parking and transfer areas should be provided to meet the needs of mass transit. * This policy is still appropriate. Staff is recommending that this policy be expanded to include higher density residential areas and provision of bus stop facilities. Review of development plans should be coordinated with Southwest Metro Transit. Planning Commission October 8, 1997 Page 13 The City will continue an ongoing maintenance program in order to maximize the community's investment in transportation facilities. * This policy is still appropriate. 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. * This policy is still appropriate. 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. * This policy is still appropriate. The City will implement roadway design standards and inspection practices which insure proper construction. * This policy is still appropriate. Chanhassen should require sidewalks and/or trails in commercial, industrial and medium and high density residential areas; adjacent to schools and other public buildings; and along one side of collectors and other high volume roads. * This policy is still appropriate. However, the policy should be mandatory, rather than prescriptive. The City will support Federal, State, Metropolitan and local efforts directed toward the timely construction of Trunk Highway 169/212, upgrading of Hwy. 5, relocation of Hwy. 101 and other facilities serving the area. * This policy is still appropriate. Staff is recommending that Highway 41 be specifically added to the list. Chanhassen will coordinate efforts with Eden Prairie and other appropriate jurisdictions to insure that Highways 5 and 101 continue to function effectively. * This policy is still appropriate. Planning Commission October 8, 1997 Page 14 Chanhassen will coordinate the construction and maintenance of hard surfaced local streets, collectors, and arterials. Within the Rural Service Area, the City will provide and maintain a transportation system consistent with the needs of agricultural land uses. * This policy is still appropriate. RECOMMENDATION Please review the attached information and be prepared to provide input and direction in preparing revisions to the goals and policies. In addition, please advise staff of any information needed for updating the plan. ATTACHMENTS 1. Metropolitan Urban Service Expansion Area Analysis 2. MUSA Areas map 3. Trunk Sanitary Sewer System 4.

TRANSIT INSERT FOR CHANHASSEN COMPREHENSIVE PLAN PUBLIC TRANSIT IS GOOD PUBLIC POLICY If it is agreed that a"good public policy"is a policy which provides benefit to a large majority of the public, then public transit is good public policy for Chanhassen. A case can be made that everyone receives benefit from public transit, even those who do not ride on a public transit system. For those who do not ride on a public transit system, some of the benefits include: • Economic vitality of businesses--Chanhassen businesses need workers and workers have to get to work. Workers using transit are reliably on time for work. If the workers are getting to work using their own vehicles, those vehicles need to be"stored" in a parking lot during the day. Those parking lots need repair after a certain amount of use. The cost of the parking lot, as well as its repairs and maintenance, all become"business expenses." • Congestion mitigation--The congestion on the major thoroughfares in Chanhassen is increasing steadily. Highway 5/212, C.R. 41, T.H. 101, T. H. 7, T. H. 169, and other collector roads are all suffering from congestion during the peak hour traffic times. The"peak hour"usually refers to the period of time when people are coming home from work. However, most would acknowledge two other times of congestion--the morning"peak"when people are getting to work and the noon"peak"when people are running their errands and headed for lunch. • Infrastructure needs are minimized--In conjunction with congestion mitigation, is the postponement of additional infrastructure. If people are utilizing public transit instead of their own vehicles, the Chanhassen's roads will be less congested and therefore will not require expansion or repair as quickly. • Air and Water Quality--The volume of pollutants contributed to the air and to the city's stormwater system is reduced by the use of public transit. The exhaust fumes distributed by one bus transporting 35 people is substantially less than the exhaust fumes distributed by 35 individual vehicles. The same is true for the volume of pollutants that are flushed through the storm water systems from the roads and parking lots. For those who do ride on a public transit system, some of the benefits include: • Access to jobs and services--For those who are transit dependent, there is a viable alternative to owning and operating their own vehicle in order to get to work or to have access to services, such as doctors, shopping, etc. The"transit dependent"population includes a variety of individuals, including kids and young adults who are not old enough to drive, elderly, those on limited or fixed incomes, and disabled individuals. • Regional access--For those who are transit dependent,there is better access to jobs and services on a region-wide basis. Because the transit system in the Metropolitan Area is regionally coordinated, it is possible to access jobs and services in the majority of the seven-county metro area. • Individual "savings"--In 1996 dollars, a rider from Eden Prairie to downtown Minneapolis saves approximately$3,200 in vehicle and parking costs compared to a driver even after paying the fare to ride the bus. Other transit service benefits exist, as well, including meeting the transportation needs of special groups and service organizations within the community and provision of facilities that serve more than just transit purposes. The main public transit service available to Chanhassen residents and businesses is provided by the Southwest Metro Transit Commission. ORGANIZATIONAL STRUCTURE OF SOUTHWEST METRO TRANSIT Southwest Metro is an"opt out", or replacement transit, agency, operated under a joint powers agreement,by and for the cities of Chanhassen, Chaska, and Eden Prairie. The agency's mission is to provide transit services for the three communities. Southwest Metro was organized in 1986 in accordance with Minnesota State Statutes, which provided that a city,or group of cities,meeting certain criteria,may"opt out"of the regional transit system(then known as the Metro Transit Commission, or MTC) and organize its own transit system. Chanhassen, Chaska, and Eden Prairie chose to opt out at that time. The oversight agency for all transit agencies was designated to be the Regional Transit Board (RTB),the duties of which were absorbed by the Metropolitan Council as a result of the 1994 Metro Governance legislation. Representation to the Commission is split by the three service communities in order to provide for - balanced direction by the Joint Powers organization. Each of the communities has one Council member and one appointed citizen member on the Commission. A rider representative serves as the seventh member of the Commission. Rider representation rotates from one city to the next in two- year increments to provide balanced representation. SERVICES There are several services provided by Southwest Metro, including: Express Service This service provides express bus trips for passengers working in Downtown Minneapolis. Riders are picked up at the Market and Pauly park and ride lot; then, after the pick- up, they are"expressed"to Minneapolis, most without stopping. At the end of the day,the service is reversed, taking passengers back home in the same"expressed"manner. (See Exhibit# ) Tele-bus This is a widely-used service. Residents are able to make reservations for this Bial- a-ride service which provides for"address to address" transit within Eden Prairie, Chanhassen, and Chaska. As an example, a passenger can make a reservation to be picked up at home,taken to a doctor appointment,be picked up at the end of the appointment and taken to the pharmacy,be picked up at the pharmacy and taken back home. (See Exhibit#_) Many people have standing reservations for this service, providing reliable transit service for their work needs, service needs, or to provide transit for their children after school. This service is also heavily depended upon by transit-dependent individuals. Circulator In order to provide for internal circulation within the three communities served by Southwest Metro, circulator routes were established in 1997. These routes connect riders to the major destination points within the community such as community centers, schools, shopping areas, doctors' offices, etc. The service is available on a regular basis, generally"circulating" through the community on an hourly basis. Circulator routes serving Chanhassen provide the community with direct connection to Eden Prairie and to Chaska. (See Exhibit# ) Reverse Commute To serve the businesses in the area, the local Chambers of Commerce created a Reverse Commute Task Force, which,in conjunction with jobs skills training services of Hennepin County and the City of Minneapolis,helped to match jobless individuals in Minneapolis with Chanhassen employers suffering from labor shortages. These routes start in Minneapolis and bring passengers to job sites in Chanhassen. (See Exhibit#_) Southwest Metro's Reverse Commute Program is the longest-running program in the Nation. Starting with only five passengers in 1992, the program has grown to serve approximately 400 - 450 passengers and 45 - 50 employers. Special Routes Southwest Metro provides special service routes to regional locations, including Southdale and the Mall of America and the Minneapolis-St. Paul Airport. Other Services Because the agency's mission is to"meet the transit needs of the community," Southwest Metro provides a variety of other transit opportunities. For example, group rides are available for a variety of businesses, schools, organizations, and others. Whenever possible, Southwest Metro provides buses for little, or no charge, for community purposes in Chanhassen and the other two service communities. For example, Councils and Commissions sometimes need to take"field trips." Southwest Metro has also made its services available for any emergency which may occur in the community. Often times a heated bus can be helpful in situations of natural disasters such as fires,tornadoes, or other natural disasters. COORDINATION WITH OTHER REGIONAL TRANSIT SERVICES Because it is considered a metropolitan-area-wide system, the Metro Council sets regional transit policy and facilitates the coordination of all the transit services in the Twin Cities Metropolitan Area. As evidence of this, one of the goals of coordination is to provide a"seamless" transit system for the users. Even though Southwest Metro does not provide direct service to St. Paul from Chanhassen, it is easy and convenient for someone to get to St. Paul by starting on a Southwest Metro bus in Chanhassen and transferring to an Metro Transit bus from the Mall of America or from Downtown Minneapolis. (See Exhibit# ) Other services coordinated by the Metropolitan Council which are also available to Eden Prairie include: • Vanpooling--Vanpools exist in the Twin Cities Area. Some businesses support their own vanpooling systems for their employees. • Metro Commute Services--A service developed by the Minnesota Department of Transportation (MnDOT),Rideshare is available to coordinate sharing of rides by individuals who travel similar routes,mostly via cars. This service mainly provides for carpooling coordination. • Community Service Organizations--While less formally organized, it cannot be ignored that many service groups in Chanhassen provide additional transportation services to individuals and groups in need. Many of Chanhassen's churches and service organizations have a van or a small bus which is made available using volunteer drivers. There is room for each of these services to operate in Chanhassen. The transit needs of the population are such that there is no "competition"for provision of services. Rather, each service-- whether regional or local--aids in meeting the needs of its particular clientele. FACILITIES AND EQUIPMENT Park& Ride Lot Chanhassen is served by one park and ride facility located at the intersection of Market and Pauly Boulevards. Through a coordinated effort,the City of Chanhassen and Southwest Metro are looking for a new location for the facility. The current site will be under construction due to Downtown redevelopment plans in the future. The park and ride facility consists of a small protective shelter adjacent to a parking lot for 120 cars. (See Exhibit#_) Because the current lot is at capacity, any new facility will need to take into account the growing population in Chanhassen. Bus Garage The agency's fleet of buses are located at the garage. Because the Eden Prairie School District moved its bus operations to a new location in 1995,it no longer needed the facility on Scenic Heights Road, adjacent to the School District Headquarters. In addition, the property upon which the bus garage was located was condemned by MNDOT for future Highway 212 right- of-way. MNDOT agreed to allow Southwest Metro to use the garage until the highway was constructed. A site search has begun for a new facility. (See Exhibit# ) Transit Hub Southwest Metro has taken possession of 23+ acres at the southwest corner of Highway 5 and Prairie Center Drive in eastern Eden Prairie for construction of a transit hub. Funding for the land and construction of the transit hub was authorized through federal ISTEA (Intermodal Surface Transportation Efficiency Act) funds, with matching funds from the Metropolitan Council, for a project estimated at$5.4 million. The transit hub will be the future headquarters of Southwest Metro. On the parcels adjacent to SMTC's offices,there will be transit related development, including services that would be utilized by riders and businesses that would benefit from access to transit. Future hubs are planned within the system, particularly in the western portion of the service area, and ideally near the border between Chanhassen and Chaska. This location would be ideal for serving the growing population in Chanhassen and areas south and west. New Buses In late 1995, Southwest Metro took possession of its own buses, including 13 large and 9 small buses. These buses were funded through a grant from the Metropolitan Council, making Southwest Metro the only transit agency other than Metro Transit(formerly MCTO) to own its own fleet of buses at that time. By the end of 1997, an additional 12 vehicles(8 large and 4 small) will be added to the fleet, for a total of 34 buses. Grant applications have been made for more vehicles in 1998 to bring the total to 40 buses. Service Growth Each year for the past three years,ridership has increased by 25%! (See Exhibit # )This is incredible considering that extremely little transit service existed in this part of the Metro area before Southwest Metro was organized to provide that service. Southwest Metro's 1996 ridership reports show that over 40,000 trips are taken on the system each month. At this point in time, all the buses are being fully utilized. The agency receives regular requests to add service in a variety of areas, especially Tele-bus. While this is one of the more expensive services to operate, it is also the most popular with residents and businesses needing specialized transit service. Planned Stuff for 1997 - 2002 Service Projected service needs over the next five years included: • Expansion of Reverse Commute--In the Twin Cities Metro area, this type of service is growing steadily. SMTC has received a grant for$1.3 million to develop and fine-tune the reverse commute program. Beginning in 1999 and for the following three years, the agency will strengthen ties between job developers,businesses, and transit, and expand the reverse commute program in this area. • Service Expansion--In addition to the circulators and reverse commute expansion,the agency has received requests for expanded service to: Ridgedale, Waconia Hospital and medical services, St. Francis Hospital and medical services, St. Paul,more connections to Bloomington, and other neighboring communities. In addition, there is a strong push for service along I-494, connecting west to the three service communities. • Garage Replacement--Southwest Metro has been informed of the timing of the construction of Highway 212. As noted above, the agency's garage is located in the right-of-way for that highway. Therefore,the agency is actively searching for a new location. Other areas in which Southwest Metro will be working include: Planning for Future Developments to provide transit-friendly access, particularly at businesses and multifamily housing projects Coordination with City Comprehensive Plan Document to take advantage of pooling financial resources, coordinating facilities needs, planning for and meeting the future needs of residents and businesses TDM and Congestion Mitigation Planning to coordinate efforts of the City and Southwest Metro in developing plans that provide help to reduce trip levels on area roads through incentives or other traffic demand management strategies Facility coordination by comparing the respective CIPs of the City and Southwest Metro to maximize the potential to share usee of public facilities and,therefore,maximize impact of tax dollars Z1' 0 ).1k �Ik VA 1 �� u..l Cii Z N I.r Plq � N w '°. ~Or i ''': PI UaS WI ..

Chapter 20 of the Chanhassen City Code is amended by adding Article 23 XXX to read: 24 25 26 ARTICLE XXX. BLUFF CREEK WATERSHED DISTRICT 27 28 DIVISION 1, BCW DISTRICT 29 30 Section 20- 1460 Purpose. 31 32 The Bluff Creek Watershed Area and the development within it have a major influence 33 on environmental quality in the City and the region. Development within the corridor must be 34 designed with utmost sensitivity to the environment and the development pattern must be of a 35 quantity and quality other than what might occur in the absence of specific standards. The 36 purpose of the District is to: 37 38 (a) Protect the Bluff Creek corridor, wetlands,bluffs, and significant stands of mature trees 39 through the use of careful site design, protective covenants, sensitive alignment and design of 40 roadways and utilities, incorporation of natural features, landscaping, techniques outlined in the 41 City's Surface Water Management Plan, and the practices delineated in the City's Best 42 Management Practices Handbook. 43 2 1 (b) Encourage a development pattern that allows people and nature to mix spanning multiple 2 ecosystems. Development in the corridor should be designed ecologically and built around 3 natural features such as trees, wetlands, and bluffs. Significant natural features should impact 4 development rather than development impacting significant natural features. The natural 5 qualities of the corridor should be preserved for recreation and to ensure sufficient habitat area 6 for wildlife. 7 8 (c) Foster the creation of a greenway connecting Lake Minnewashta Regional Park and the 9 Minnesota River Valley. The greenway will serve as an uninterrupted pedestrian trail and 10 bikeway system affording opportunities for recreation,education,physical fitness and 11 transportation. 12 13 Sec. 20 - 1461 Intent. 14 15 The City intends that all development within the district should blend into the natural 16 environment while protecting Bluff Creek and sensitive land areas abutting and in the vicinity of 17 the watercourse and its tributaries. The criteria by which new development in the district shall be 18 judged are as follows: 19 20 (a) Consistency with all provisions of the Comprehensive Plan and the Bluff Creek 21 Watershed Natural Resources Management Plan, as amended from time to time; the Surface 22 Water Protection Program; all provisions of the Zoning Ordinance and Subdivision Ordinance 23 not specifically overridden by the provisions of this district; and all other applicable land use 24 regulations. 25 26 (b) Preservation of the natural conditions found in the Primary Zone and to the greatest 27 extent possible, preserving significant resources and minimizing impacts in the Secondary Zone 28 through density transfers, cluster development and other practices which minimize the removal 29 of vegetation, minimize site grading, and application of practices found in the City's Best 30 Management Practices Handbook. 31 32 (c) Creation of a suitable balance between the amount and arrangement of open space, 33 landscaping, view protection,bluff protection, and vegetation protection and the design and 34 function of man-made features on the other. 35 36 (d) Creation of an interconnected open space network that preserves migratory patterns for 37 wildlife and facilitates recreational opportunities for people. 38 39 Sec. 20— 1462 District Application. 40 41 The BCW district shall be applied or superimposed(overlaid) upon all zoning districts as 42 contained herein as existing or amended by the text and map of this ordinance. The regulations 43 and requirements imposed by the BCW district shall be in addition to those established for 3 1 districts which jointly apply. Under the joint application of the districts, the more restrictive 2 requirements shall apply. 3 4 Sec. 20 - 1463 Boundary Delineation. 5 6 (a) Generally. Primary and Secondary Zones shall be subject to the requirements established 7 herein, as well as restrictions and requirements established by other applicable city ordinances 8 and regulations. The Bluff Creek Watershed regulations shall not be construed to allow anything 9 otherwise prohibited in the zoning district where the overlay district applies. 10 11 (b)Boundaries; maps. The Primary and Secondary zones include land that is generally 12 defined in this article and in the Bluff Creek Watershed Natural Resources Management Plan. 13 Boundaries as established by officially adopted city maps shall be prima facie evidence of the 14 location and type of watershed zone. The official maps shall be developed and maintained by the 15 planning department. The applicant shall provide appropriate technical information, including 16 but not limited to, a topographical survey, flora and fauna survey and soil data deemed necessary 17 for the city to determine the exact watershed zone boundary. The planning director shall make a 18 determination to maintain the officially designated watershed zone boundary or if the boundaries 19 need to be corrected on city plans and maps based upon the data that is supplied. Data for 20 watershed zone delineation shall be generated and provided by a qualified professional 21 specializing in watershed management,environmental science or other related profession. The 22 applicant may appeal the planning director's determination of the watershed zone boundary and 23 type to the city council. 24 25 Sec. 20 - 1464 Impervious Cover and Slopes. 26 27 To the greatest extent possible, all development shall minimize the amount of impervious 28 surface by clustering development, using common access drives and utility corridors and 29 minimizing building footprint size. Roads, walkways,bike trails, and parking areas must be 30 designed parallel to natural contours with consideration to maintaining consolidated areas of 31 natural topography and vegetation. Management of surface run-off caused by impervious cover 32 shall be designed using practices delineated in the city's Best Management Practices Handbook. 33 34 Within the Secondary Zone of the BCW district, areas with average slopes exceeding 25% 35 shall be preserved in their natural state and maintained as permanent open space. Areas with 36 average slopes less than 25%but greater than 10% shall not exceed an impervious surface 37 coverage of 25%. Impervious coverage for areas where average slopes are less than 10% shall be 38 governed by the underlying zoning district. 39 40 Sec. 20 - 1465 Bluffs. 41 42 Bluffs shall be preserved as provided for under Article XXVBI. 4 1 Sec. 20- 1466 Site Views. 2 3 Through environmentally sensitive design such as "terrain adaptive architecture"(see Figure 4 1.), landscaping and site planning, site views both to and from the BCW district shall be 5 preserved and enhanced to the greatest extent possible so as to maintain views that reflect and 6 protect the natural beauty of the BCW District. Special attention should be given to views that 7 are highly accessible to the public such as scenic overlooks,bridges and trails. Clustering of 8 development away from natural overlooks is encouraged. Develop terrain-adaptive •~ ? architecture for steep slopes.

"Published in APA PAS Report#466" 11 12 13 Sec. 20 - 1467 Density Transfer. 14 15 Density transfers may be used in areas where portions of the site are unsuitable to 16 development because of physical barriers such as bluffs (excessive slopes), wetlands or soil 17 constraints. These density credits may be transferred to unconstrained parts of the site. The 18 following environmental conditions may qualify for density transfers: 19 20 a) Land slopes in the Secondary Zone that exceed 25% on average. 21 22 b) Land located within 100 feet of wetlands with very poorly drained soils,bodies of water 23 or watercourses. 24 25 c) Land with a suitable natural habitat to endangered or threatened species or a fragile 26 ecosystem. 27 28 d) Other lands as determined by City Council. 29 5 1 Sec. 20— 1468 Standards and Guidelines for Single-Family Attached or Cluster-Home 2 PUDs. 3 4 Single-family attached, cluster, zero lot line, and similar dwelling types shall only be allowed 5 on sites designed for low, medium or high density residential uses by the City of Chanhassen 6 Comprehensive Plan. 7 8 Sec. 20 - 1469 Natural Habitat Preservation. 9 10 a) Natural habitat areas within the Primary Zone shall be preserved as permanent open 11 space. Any development that occurs shall be directly related to the continuous greenway along 12 the creek from the Minnesota River to Lake Minnewashta as outlined in the Bluff Creek 13 Watershed Natural Resources Management Plan. 14 15 b) Where possible, any disturbances of natural habitat areas within the Secondary Zone shall 16 be avoided. Any alterations to the Natural Habitat within the Secondary Zone shall adhere to the 17 practices delineated in the city's Best Management Practices Handbook. 18 19 Sec. 20- 1470 Natural Habitat Restoration Plan 20 21 If natural habitat areas located within the Secondary Zone will be disturbed during any stage 22 of development, the applicant shall submit a detailed plan identifying the resources that will be 23 disturbed and a corresponding restoration and/or mitigation plan. Such restoration might include 24 wetland mitigation and replanting of habitat significant to endangered and threatened species. 25 26 Sec. 20 - 1471 Open Space Requirements. 27 28 Open space shall comprise 100% of the area located within the Primary Zone. The City using 29 data that will be provided by the applicant will establish the boundary for the Primary Zone. 30 31 Sec. 20- 1472 Structure Setbacks. 32 33 All structures shall be setback a minimum of 30 feet from the Primary Zone. No disturbance 34 of the site shall occur within the first 20 feet of such setback. 35 36 SECTION 9.
