The residential developments that were approved were smaller in the number of lots than have been completed in the past. If the Villages on the Ponds was not approved, the city would have only approved 58 new single family lots. Residential Townhomes at Creekside 25 units Oak Ridge of Minnewashta 23 units Melody Hill 10 units Villages on the Pond up to 322 units Commercial/Industrial Technical Industrial Sales Hiway 5 Centre/Gold Metal Sports Paws, Claws and Hooves Boarding Chuck's Grinding St. Hubert's Church Americinn Motel Suites Villages on the Pond Review of a 60 acre development and creating the PUD. The project included the education of staff and the commission on the principals of New Urbanism, traffic calming, etc. Staff worked to receive additional public funding including $190,000 for transit and $500,000 under the Livable Communities Demonstration Account for enhancement of the public realm. Comprehensive Plan Amendments Completion of the Bluff Creek Natural Resources Plan This document which becomes a part of the comprehensive plan and will be a guide to the development along Bluff Creek. The plan also provided a process to guide future land uses in the southern portion of the city. 1996Community Development Highlights Page 2 Zoning Ordinance Amendments Cellular Tower Ordinance This ordinance was in response to industry changes and the new telecommunications law. After a comprehensive study of other communities and review of the literature, staff drafted an ordinance that meets industry needs while protecting the city's interests. Pond Treatment Ordinance This ordinance was drafted by staff with the assistance of the environmental commission in response to numerous requests to treat storm water ponds and wetlands. Private Driveways This ordinance addressed the issue of subdividing in an established neighborhood when there is not public frontage(Maplewood Circle). The outcome was to leave the ordinance as it was. Environmental Commission The environmental commission is now meeting on a regular basis. They have already drafted an ordinance for treating ponds and wetlands. The commission will also be spear heading the Arbor, Earth And Park Pride Day activities. They have also been assisting in the city's sump pump program. Related Issues Staff has been working with the City's Chamber and the Chamber from Chaska on a Business Retention Study. The purpose of this study is to determine the needs of businesses in the area so they will stay in the community and have opportunities to expand. This study has been funded by Sprint and is a joint effort with School District 112, local governments and the Chambers. 11cfs11vo121p1an1ka\review of 1996 projects.doc 3.

BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM TO: Planning Commission FROM: Kate Aanenson, AICP, Planning Director DATE: January 29, 1997 SUBJ: Comprehensive Plan Update When the Legislature passed a law stating that the comprehensive plan and the zoning ordinance must be in compliance by 1998, it has significant implications for the City of Chanhassen. As a part of the Bluff Creek Natural Resources Plan, the land use component has been updated. Those areas of the city that were not guided for a future land use were given one or in some cases a number of alternatives. The next step is to update the rest of the comprehensive plan. This is an immense task that will take at least one year. In examining the city's 1991 Comprehensive Plan, it is interesting to note that many of the goals and policies have been met. For example, the completion of the city's Storm Water Management Plan, encouraging the cooperative effort between the school district and the city (Bluff Creek Elementary and the Recreation Center),completion of the Hwy. 5 Corridor Study which revisited land uses and provided the located for the access boulevard, and most recently, the Bluff Creek Natural Resources Plan. Staff has selected Mark Koegler to assist staff in the process. As a part of the updating process, staff wanted to ensure that the public has an opportunity to comment on the elements of the plan. This is the city's growth document and the vision for our future citizens and input is vital to the adoption and implementation. Attached is Mark Koegler's comment on the process. One of the strategic components of the comprehensive plan is the staging of the MUSA line. The new growth options approved by the Metropolitan Council gives cities the ability to determine the areas to be brought into the Urban Service Area by the year 2020. Planning Commission January 27, 1997 Page 2 The exciting thing about updating the plan at this time is the city's ability to provide better data bases on the geographic information system. The city has significantly more data and will be able to provide more reliable data. In addition, we will be able to provide better maps. This should make the new comprehensive plan more user friendly. Attached are Mark Koegler's thoughts on the process and the elements that must be in the comprehensive plan as directed by the Metropolitan Council. \\cfsl wol2\plan\ka\comp plan process.doc 612-835-3160 HOISINGTON KOEGLER 499 P02 JAN 28 '97 12:53 MEMORANDUM ©© Hoisington Koegler Group Inc. WOEI TO: Kate Aanenson DATE: Mark Koegler SUBJECT: Comprehensive Plan Update and Overlay Ordinance FROM: Mark Koegler Preliminary thoughts on the Comprehensive Plan Update: The current Comprehensive Plan update is different than those that have been done in the past. Over the past few years,the TH5 Corridor Study and the Bluff Creek Watershed Management Plan have effectively planned land use for the remaining vacant areas in the City. As a result, the large scale debates on general land use issues have taken place and the emphasis of the plan will need to be to supply needed detail that supplements the general planning direction that has been set. Since the plan update will be different than those completed in the past, a different scope of work will be required for the overall effort. In general, the scope can be broken down into the following components: Task 1 • Identify What Exists - Forecast Growth This task will establish the current basis for planning in Chanhassen. It should include an update of demographic information to 1996 including current households and population based on City building permit records. The updated household and population count should be compared to the current and long range projections of the Metropolitan Council to verify or possibly modify the projections. As a component of Task 1, the City will need to update base mapping. Current maps should be prepared in a GIS format that depicts existing land use, transportation, and parks. If possible, it would be helpful to establish a data base link between mapping and property information such as appraised value. Such a base could be helpful in addressing the financial impacts of the future mix of land uses that are identified in the plan. At a minimum, housing information could be included in the land use data base providing a constant tool for comparing the quantities of single family housing versus other attached forms of housing (possibly even affordable vs higher cost housing). Task 2 - Involve Stakeholders In order for the Comprehensive Plan to effectively serve the City of Chanhassen, it is important that it have support from residents and business persons in the community. Public participation in the planning process needs to recognize that a great deal of public input has gone into shaping the plan into its present form. Both the Highway 5 Plan and the Bluff Creek Plan involved the general public 7300 Metro Boulevard,Suite 525,Minneapolis,Minnesota 55439 (612)835-9960 Fax(612) 835.3160 612-835-3160 HOISINGTON KOEGLER 499 P03 JAN 28 '97 12:53 Memorandum January 28, 1997 Page 2 including directly impacted property owners. As a result, the public input process needs to have two components. First, it needs to provide a summary of what has taken place and the basis for the decisions that have been made. This component is important because the City is not looking to "reinvent the wheel"when it comes to land use decisions that have been adopted by the City Council as part of previous studies. Secondly, it needs to solicit ideas from the public on policies and actions that will be necessary to implement the plan. In other words, present the general concepts as the direction that has been adopted by the City but seek ideas and assistance into how those concepts are to be implemented over the long run. An appropriate format for seeking public involvement in the Plan update might be to schedule a series of public informational meetings in different geographic areas of the community. The appropriate number of such meetings may be only two with breakdowns north and south of TH5 or they may involve 4 or 5 total sessions with different geographic delineations. Presumably, the Planning Commission will be the body charged with overseeing the plan update and therefore, they would host the public information sessions. In addition to the organized public involvement sessions, other measures should be used to keep residents informed during the planning process. Articles in the local paper as well as articles in the community newsletter or even special mailings could be used to keep the public informed of progress as well as key meeting dates for various Planning Commission discussion items. Task 3 - Develop the Plan and Strategies - Seek Approvals Based on input received in Task 2, this task will involve the detailing of plan concepts and policies and the documentation, in draft form, of the Comprehensive Plan. The following will be included as part of the plan: 1. Introduction and purpose 2. Policies 3. Summary of previous planning efforts 4. Land Use Section* 5. Housing Section* 6. Water Resources Management* 7. Historic Preservation* 8. Solar Access* 9. Transportation* 10. Aviation* 11. Wastewater* 12. Park and Recreation* 13. Water Supply* 14. Community Facilities 15. Ordinance Framework* 16. Capital Improvement Program* 17. Action Plan for Implementation * Items identified in your outline dated July, 1996. 612-835-3160 HOISINGTON KOEGLER 499 PO4 JAN 28 '97 12:54 Memorandum January 28, 1997 Page 3 This task will involve a series of meetings with the Planning Commission to review various graphics and text related to each of the plan components identified above. This task will also involve the formal public hearing. If the public has been kept informed during the planning process and has had the opportunity to provide meaningful input, the public hearing should become almost a formality. Building public ownership of the plan during the planning process will not only lead to a less contentious public hearing but it will also provide greater support for implementation of the plan. Task 4 - Document the Results After the draft Comprehensive Plan has been approved by the Metropolitan Council and adopted by the City Council, this task will involve putting the document into final form. Tasks will include desktop publishing of the text, completion of final maps and graphics and printing of the required number of copies. In addition to the full plan, the City may want to consider a larger printing of a plan summary that could be available for wider distribution. Such summaries usually include the future land use map on one side and summary text on the other side. Schedule Based on the components of the comprehensive plan that are identified above, it seems reasonable to establish a one year time frame for overall completion. Establishing a schedule with public hearings in February of 1998 should be realistic. Over the course of the next month or so, the Metropolitan Council is going to be setting up meetings with municipalities to review comprehensive planning requirements. Information from those meetings may be helpful in determining a final schedule.

MEMORANDUM TO: Planning Commission FROM: Kate Aanenson, AICP, Planning Director DATE: January 30, 1997 SUBJ: Bluff Creek Natural Resources Pian Implementation With the adoption of the Bluff Creek Natural Resources Plan, the next step is to develop the tools to implement the vision. Again, staff will be working with Mark Koegler to develop this ordinance. The process and outcome will be similar to that of the Highway 5 Corridor Study. This process will be a public hearing and staff has been requested to include the builder's association in the review. As stated during the review and adoption of the plan, this area of the city is very unique and in order to preserve the natural features, development patterns will be different than what has been done in the past. The proposed time line for this project is 6 months. It is hoped that we will be holding public hearings on an ordinance this summer. Attached are Mark Koegler's comments on the process. \\cfs I\vol2\plan\ka\bluffcreek ord proposal.doc Preliminary Thoughts on the Bluff Creek Overlay Zoning Ordinance: The Bluff Creek Overlay Zoning Ordinance is likely to be modeled after Ordinance No. 212 which establishes Highway Corridor Districts. Because of the extensive work that was done as part of the Bluff Creek Watershed Natural Resources Management Plan, the purpose and intent statement of the ordinance should reflect information and findings found in the Plan. The format of the ordinance itself should rely on liberal use of graphics to illustrate various conditions and requirements. Establishing a time line for the preparation of the ordinance should consider certain timing elements of the Comprehensive Plan. For example, public presentation of the draft ordinance either to the public at-Iarge or to specific groups such as landowners and/or developers should not occur until the public information sessions outlined in Task 2 of the Comprehensive Plan have been conducted. Going public with specifics on the ordinance could be perceived as putting the cart before the horse if the land use plan has not been presented to a wider audience. Work in preparing the ordinance could proceed immediately based on the approved Management Plan. In general, I would foresee a time frame of approximately 6 months for the preparation of the complete ordinance allowing for Planning Commission review and coordination with the Comprehensive Plan schedule. (, CITY OF i lo, CHANHASSEN � i 690 COULTER DRIVE • P.O. BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM TO: Planning Commission FROM: Kate Aanenson, AICP Planning Director DATE: January 30, 1997 SUBJ: Housing Goals Update Attached is the Livable Communities Act, Goals and Action Plan. What I will be sharing with the Planning Commission at their work session is the current building trends, and locations of existing and proposed housing that will meet the city's goals. BACKGROUND In November 1995, the City of Chanhassen agreed to participate in the Livable Communities Act and in December 1995 adopted housing goals. In June 1996, the City adopted an action plan for the implementation of the housing goals. The three areas the city has to address in meeting requirements of the Livable Communities Act are Life-cycle, Density and Affordable. • Life-cycle housing is made up of two components. The number of non-traditional housing or percentage of housing that is not single family detached. The other component is the ratio of owner occupied units to renter units. • Density compares the number of units to the acres of development. This ratio is applied to low density and multifamily. • Affordable is that percentage of new housing units that will be affordable. For 1997, the Met Council considers those owner occupied units under$120,000 affordable. Rental affordability is the percentage of rental units with rents under$683. Livable Communities Act Page 2 DENSITY GOALS Between 1993 and 1997, the city has been averaging 1.97 net units an acre on the single-family (low density) and 6.47 units per acres on the multi-family(medium and high density). In Chanhassen, low density includes twin homes. This highlights an issue the Planning Commission has been raising for a long time—if the city allows development to occur below the designated density, then where will this lost density be replaced. The benchmark the city should be trying to achieve in single family detached developments is 1.8-1.9 units/acre. The city's goal is 1.8 units an acre net density. In the multifamily district, the benchmark is 10-14 units/acre. The city index is 11 units/acre. The city's goal is 9-10 units per acre. As indicated earlier, this number has moved farther from the benchmark because of the number of projects approved at the medium density range. The only way to achieve the density benchmark in the multifamily land use would be to build developments at the maximum density permitted. In cases where the development is appropriate, give density bonuses as permitted in the PUD ordinance. The city currently has limited high density development. The majority of projects are being developed at 6 units an acres, therefore, a significant number of developments will have to be built in excess of 14 units an acre to increase the multi-family units per acre density to achieve the benchmark. Table 1 Housing Goals Agreement Single-Family Detached 1.5/acre 1.8-1.9/acre 1.8/acre net Multifamily 11/acre 10-14/acre 9-10 LIFE CYCLE GOALS The method for determining life-cycle housing is to look at the future number of households the Met Council has predicated for the city in the next 15 years and establish what percentage of owner to renter the city will try to achieve. The type of non-single family includes apartments, townhouses, 3 and 4 plexes, etc. Assuming the Met Council prediction of 5,784 new households, the city's goal is an 80%owner to 20% rental mix which would mean that 4,627 units should be owner occupied and 1,157 should be rental units. In the 1990 comprehensive plan, the approved housing goal was for 34% of the housing units to be non-single family detached. With the types of owner occupied and Livable Communities Act Page 3 rental there is a large variety of housing options. The proposed Met Council benchmark is 67 / 75 and 25 / 33 ratio of owner to renter. The city index according to the Met Council is 85 / 15. The Heritage Park Apartments, with 60 units, was built in 1989-90 and in 1995-96, Centennial Hill (Senior Project), with 65 units was built. Even at 1,157 units over the next 15 years it would mean 70 units a year. The important number to keep in mind is for every eight units of owner occupied, the city should be developing two units of rental. Table 2 Housing Goals Agreement Life-Cycle City Index Benchmark Goal Type(Non-Single Family 19% 35-37% 34%* 1991 Comp Detached) Plan Owner/renter Mix 85/15% (67-75)/(25-33) % 80/20 AFFORDABLE The definition of affordable owner occupied units are those units under $120,000 in homestead valuation. Affordable rental units are those units with rents under$683 a month for two or more bedrooms. To determine the number of affordable ownership, the first step is to determine the number of owner occupied units. As stated previously with an 80/20 ratio of owner occupied units to rental units,the number of owner occupied households over the next 15 years could be 4,627. The number of rental could be 1,157. The benchmark the Met Council is recommending is 60-69% ownership affordable and 35-37%rental affordable. The city in 1995 was at 37% affordable rental, according to the Met Council. According to 1996 data, 24%of Chanhassen homesteaded homes are affordable. The city's goal is 50%of ownership housing being affordable. That means that 50%of all new homes constructed in the next 15 years should be under the $120,000 in valuation.

A component of the Comprehensive Plan is the Housing Element. The Goals and Policies that were adopted in 1991 are still relevant to today's housing strategies. Goal To provide housing opportunities for all residents, consistent with the identified community development goal. Policies Existing housing within the city should be maintained and improved and revitalization of older developed areas should be encouraged. The City of Chanhassen will attempt to provide adequate land for projected housing growth and to provide opportunities for persons of a range of incomes. Livable Communities Act Page 5 As appropriate state and federal funding permits, efforts should be made to provide low and moderate housing where needed, to provide balance to the generally higher cost of housing. New construction programs may provide a source of such housing. Plans and ordinances for the City of Chanhassen should ensure that adequate amounts of land are designated to accommodate projected desired residential growth. The city should promote the use of state and federal programs designed to reduce land costs for developers of low and moderate income housing. The City of Chanhassen 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. 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 are not provided with necessary urban services. If demand becomes apparent, the city will promote the construction of senior citizen housing in locations convenient to shopping and medical services. The development of alternative types of housing such as patio homes, townhouses, and quadplexes should be permitted to supplement conventional single-family homes and apartments providing that they are compatible with appropriate land use practices and are representative of high quality development. New residential development should be discouraged from encroaching upon vital natural resources or physical features that perform essential protection functions in their natural state. Housing developments such as PUDs, cluster development and innovative site plans and building types should be encouraged to help conserve energy and resources used for housing. Property and code enforcement policies which encourage maintenance and rehabilitation of both owner occupied and rental housing should be encouraged. The city should continue to ensure non-discrimination in sale and rental of housing units. Citizen participation in developing plans and implementing housing programs is encouraged in redevelopment, rehabilitation, and in planning for future housing. \\c fs 11voI2\plan\ka\houseup.doc 2 C QTY TF CHANHASSEN 690 COULTER DRIVE • P.O. BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM TO: Planning Commission FROM: Bob Generous, Senior Planner DATE: January 30, 1997 SUBJ: PUD Ordinance BACKGROUND In July 1995, the city amended the PUD ordinance as part of the"glitch"ordinance revising the calculation of density from gross to net density, consistent with the requirements of the comprehensive plan. In November 1992, the city amended the PUD ordinance. At that time, the minimum lot size for single-family detached housing was established at 11,000 square feet with an average lot size of 15,000 square feet. Staff and the Planning Commission had recommended 9,000 square foot minimum lots, however, the City Council revised the number. In the summer of 1991, the city amended the PUD ordinance, creating an expanded intent section for the ordinance and establishing procedural requirements. It should be noted that the reference to gross density was specifically addressed and it was the intent of the ordinance to use gross density calculations to determine the number of units that would be permitted as part of a development. However, the comprehensive plan specified net density. In November 1986, the city adopted a PUD ordinance. In November 1995, the City of Chanhassen agreed to participate in the Livable Communities Act and in December 1995 adopted housing goals. In June 1996, the City adopted an action plan for the implementation of the housing goals. The three areas the city has to address in meeting requirements of the Livable Communities Act are Life-cycle, Density and Affordable. Planning Commission PUD Ordinance Page 2 • Life-cycle housing is made up of two components. The number of non-traditional housing or percentage of housing that is not single family detached. The other component is the ratio of owner occupied units to renter units. • Density compares the number of units to the acres of development. This ratio is applied to low density and multifamily. • Affordable is that percentage of new housing units that will be affordable. For 1997, the Met Council considers those owner occupied units under$120,000 affordable. Rental affordability is the percentage of rental units with rents under$683. Housing Element of the Comprehensive Plan The comprehensive plan provides guidance in revisions to the PUD ordinance that may be appropriate. The following goal and policies are directly related to what we would like to accomplish as part of any revisions to the PUD ordinance. Goal: To provide housing opportunities for all residents, consistent with the identified community development goal. Policies: The City of Chanhassen will attempt to provide adequate land for projected housing growth and to provide opportunities for persons of a range of incomes. 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 are not provided with necessary urban services. The development of alternative types of housing such as patio homes, townhouses, and quadplexes should be permitted to supplement conventional single-family homes and apartments providing that they are compatible with appropriate land use practices and are representative of high quality development. New residential development should be discouraged from encroaching upon vital natural resources or physical features that perform essential protection functions in their natural state. Housing developments such as PUDs, cluster development and innovative site plans and building types should be encouraged to help conserve energy and resources used for housing. Planning Commission PUD Ordinance Page 3 Bluff Creek Study In December 1996, Chanhassen approved the Bluff Creek Study which provided direction in land use and development design along bluff creek. While some of the elements for the implementation will be incorporated in an overlay district,portions can and will be implemented as part of the PUD ordinance. In addition, some elements such as density transfer, cluster development, enhanced standards for the preservation of natural resources may be desirable throughout the community. City Ordinances The following actions are possible actions the city should undertake to pursue life-cycle and affordable housing: • Promote Life cycle compatible with existing housing. • Review city ordinance regulations especially the PUD ordinance and lot size/zero lot and design standard including street widths. • Pursue the upper limits of zoning on new proposals where there is a density range. • Require a percentage of medium and high density to have a number of affordable units. • Provide for mixed use projects with a transit component. EXISTING ORDINANCE Section 20-501. Intent Planned unit developments offer enhanced flexibility to develop a site through the relaxation of most normal zoning district standards. The use of the PUD zoning also allows for a greater variety of uses, internal transfer of density, construction phasing, and a potential for lower development costs. In exchange for this enhanced flexibility,the City has the expectation that the development plan will result in a significantly higher quality and more sensitive proposal than would have been the case with the other more standard zoning districts. It will be the applicant's responsibility to demonstrate that the City's expectations are to be realized as evaluated against the following criteria: 1. Preservation of desirable site characteristics and open space and protection of sensitive environmental features, including steep slopes, mature trees, creeks, wetlands, lakes and scenic views. 2. More efficient and effective use of land, open space and public facilities through mixing of land uses and assembly and development of land in larger parcels. Planning Commission PUD Ordinance Page 4 3. High quality of design and design compatible with surrounding land uses, including both existing and planned. Site planning, landscaping and building architecture should reflect higher quality design than is found elsewhere in the community. 4. Sensitive development in transitional areas located between different land uses and along significant corridors within the city will be encouraged. 5. Development which is consistent with the Comprehensive Plan. 6. Parks and open space. The creation of public open space may be required by the city. Such park and open space shall be consistent with the Comprehensive Park Plan and overall trail plan. 7. Provision of housing affordable to all income groups if appropriate with the PUD. 8. Energy conservation through the use of more efficient building designs and sitings and the clustering of buildings and land uses. 9. Use of traffic management and design techniques to reduce the potential for traffic conflicts. Improvements to area roads and intersections may be required as appropriate. ANALYSIS/ISSUES The current zoning options for development on low density residential lands are the RSF district which requires a minimum lot size of 15,000 square feet, the R4 district which requires minimum lot sizes for single-family detached houses of 15,000 square feet and 10,000 square feet for each duplex unit, and the PUD district which permits a minimum lot size of 11,000 square feet but requires an average lot size within the development of 15,000 square feet. While the purpose of the PUD is to provide enhanced flexibility, due to the requirements contained in the ordinance there are severe constraints placed on the flexibility. Section 20-505 Required general standards. Density transfer within single-family developments is limited to lot size variation. Density transfer from multi-family is not permitted to low density areas. This may interfere with city efforts at preserving natural areas, such as Bluff Creek, which have a higher land use classification. The city under current ordinance would lose this density. Planning Commission PUD Ordinance Page 5 Density may not exceed the net density ranges identified in the comprehensive plan. However, as stated above, the city may lose some density due to this. In addition, in order to provide affordable housing, the city may wish to look at providing density incentives that may exceed the net density for a particular land use. Although, within the current ordinance, the city may permit up to 25 percent of the building area to be used other than those specified in the comprehensive plan. Section 20-506 Standards and guidelines for single-family detached residential planned unit developments. Minimum lot size requirements preclude the provision of zero lot line and cluster housing or attached single-family which may be appropriate designs to preserve significant natural features or to create additional open space. Section 20-508, Standards and guidelines for single-family attached or cluster-home PUDs. Non-traditional single-family housing is only permitted in these areas. There is a glitch in the ordinance that first requires a minimum lot size then states that there is no minimum lot size. Examples There are several development examples in which the city could have had more sensitive development had we had more flexibility within the PUD ordinance and better resource protection criteria. Stone Creek Addition. Part of the site was agricultural field and part of the site was heavily wooded. By reducing the lot sizes and concentrating the development in the open field, the city may have been able to preserve a large area of central hardwoods. Creekside Addition. This site is adjacent to Bluff Creek and also contains an example of a central hardwood forest. Had the city been able to transfer density within the project, the hardwood forest may have been preserved and additional view corridors to Bluff Creek and the wetland complex may have been provided. Shamrock Ridge Addition. An area of steep slopes which did not meet the Bluff Ordinance criteria, located in the western third of the project, may have been preserved had the city had a more flexible PUD ordinance. Again, the density of this area could have been transferred to less sensitive areas. Planning Commission PUD Ordinance Page 6 RECOMMENDATION Staff is requesting that the Planning Commission review the PUD ordinance and provide direction in amending the ordinance to implement city goals and policies. Specifically, staff is requesting discussion of the following ideas: 1. Since preservation of natural areas are a primary goal of the PUD, revise the process to require that 1) resource areas are identified, 2) housing and building sites are located to maximize views and access to open spaces, and 3) design road systems that incorporate 1 and 2. 2. Require that pedestrian and vehicular linkages are provided from the PUD to adjacent development. 3. Develop criteria for the transitioning of densities between existing and proposed developments. One alternative is to require lot sizes at least 80 percent as large as those required in RSF districts immediately adjacent to existing subdivisions (i.e. 12,000 square feet). 4. Eliminate minimum lot sizes for low density development and base the number of units on density. Permit zero lot line, clustered, and single-family attached housing in low density areas when appropriate. In addition, develop criteria for locating non-tradition residential developments, e.g., must be accessed via collector or arterial roadways, must be adjacent to higher density land uses or non-residential land uses,preserves significant natural features, etc. 5. Require the provision of public or common open spaces as a percent of the entire site. 6. Provide density bonuses for the provision of affordable housing including rental housing. A bonus of 25 percent in the allowed density based on the land use designation for meeting city housing goals may be appropriate. ATTACHMENTS 1.

Planned unit developments offer enhanced flexibility to develop a site through the relax- ation of most normal zoning district standards. The use of the PUD zoning also allows for a greater variety of uses, internal transfers of density, construction phasing and a potential for lower development costs.In exchange for this enhanced flexibility,the city has the expectation that the development plan will result in a significantly higher quality and more sensitive proposal than would have been the case with the use of other, more standard zoning districts. It will be the applicant's responsibility to demonstrate that the city's expectation is to be realized as evaluated against the following criteria. Planned unit developments are to en- courage the following: (1) Preservation of desirable site characteristics and open space and protection of sensi- tive environmental features, including steep slopes, mature trees, creeks, wetlands, lakes and scenic views. (2) More efficient and effective use of land, open space and public facilities through mixing of land uses and assembly and development of land in larger parcels. (3) High quality of design and design compatible with surrounding land uses, including both existing and planned.Site planning,landscaping and building architecture should reflect higher quality design than is found elsewhere in the community. (4) Sensitive development in transitional areas located between different land uses and along significant corridors within the city. (5) Development which is consistent with the comprehensive plan. (6) Parks and open space. The creation of public open space may be required by the city. Such park and open space shall be consistent with the comprehensive park plan and overall trail plan. (7) Provision of housing affordable to all income groups if appropriate within the PUD. (8) Energy conservation through the use of more efficient building designs and sightings and the clustering of buildings and land uses. *Editor's note—Section 1 of Ord.No. 149,adopted June 24, 1991,amended Art.VIII,Div. 1,to read as herein set out.Prior to amendment,Art.VIII,Div. 1,contained§§20.501-20-505, pertaining to similar subject matter and deriving from Ord.

Specific uses and performance standards for each PUD shall be delineated in a develop- ment plan. (1) Each PUD shall only be used for the use or uses for which the site is designated in the comprehensive plan,except that the city may permit up to twenty-five(25)percent of the gross floor area of all buildings in a PUD to be used for land uses for which the site is not designated in the comprehensive plan if the city council finds that such use is in the best interests of the city and is consistent with the requirements of this section. Specific uses and performance standards for each PUD shall be delineated in a PUD development plan. Supp. No. 7 1200.1 ZONING § 20-505 (2) Where the site of a proposed PUD is designated for more than one(1)land use in the comprehensive plan, city may require that the PUD include all the land uses so designated or such combination of the designated uses as the city council shall deem appropriate to achieve the purposes of this article and the comprehensive plan. (Ord. No. 149, § 1, 6-24-91) Sec. 20-503. District size and location. (a) Each PUD shall have a minimum area of five (5) acres, unless the applicant can demonstrate the existence of one of the following: (1) Unusual physical features of the property itself or of the surrounding neighborhood such that development as a PUD will conserve a physical or topographic feature of importance to the neighborhood or community. (2) The property is directly adjacent to or across a right-of-way from property which has been developed previously as a PUD or planned unit residential development and will be perceived as and will function as an extension of that previously approved development. (3) The property is located in a transitional area between different land use categories or on an intermediate or principal arterial as defined in the comprehensive plan. (Ord. No. 149, § 1, 6-24-91) Sec. 20-504. Coordination with other zoning regulations. (a) Subdivision review under chapter 18 shall be carried out simultaneously with the review of a PUD.The plans required under this chapter shall be submitted in addition to or in a form which will satisfy the requirements of chapter 18 for the preliminary and final plat.

(c) PUD plans shall be coordinated with and in compliance with provisions of article V, Flood Plain Overlay District; article VI, Wetland Protection, and article VII, Shoreland Overlay District. (Ord. No. 149, § 1, 6-24-91) Sec. 20-505. Required general standards. (a) The city shall consider the proposed PUD from the point of view of all standards and purposes of the comprehensive land use plan to coordinate between the proposed development and the surrounding use. The city shall consider the location of buildings, compatibility, parking areas and other features with response to the topography of the area and existing natural features, the efficiency, adequacy and safety of the proposed layout of streets; the adequacy and location of green areas; the adequacy, location and screening of noncompatible land uses and parking areas. Supp.No. 8 1200.3 § 20-505 CHANHASSEN CITY CODE (b) The applicant shall demonstrate that the PUD plan offers the city higher quality architectural and site design, landscaping, protection of wetlands, creeks and mature trees and buffering for adjoining properties that represent improvements over normal ordinance standards. (c) Density.An increase/transfer for density may be allowed at the sole discretion of the city utilizing the following factors: (1) Density within a PUD shall be calculated on gross acreage located within the property lines of the site in accordance with the land use plan. (2) The area where the density is transferred must be within the project area and owned by the proponent. (3) Density transfer in single-family detached area will be evaluated using the items listed in section 20-506. Density transfer eligible for multiple-family areas are not permitted to be applied to single-family areas. (4) In no case shall the overall density of the development exceed the net density ranges identified in the comprehensive plan. (d) The city may utilize incentives to encourage the construction of projects which are consistent with the city's housing goals. Incentives may include modification of density and other standards for developments providing low and moderate cost housing.Incentives may be approved by the city only after the developer and city have entered into an agreement to ensure that the low and moderate income for a specific period of time. (e) Hard surface coverage shall be limited as follows: Comprehensive Hard Surface Plan Designation Coverage (%) Low or medium density residential 30 High density residential 50 Office 70 Commercial (neighborhood or community) 70 Commercial (regional) 70 Industrial ?0 Individual lots within PUD may exceed these standards as long as the average meets these standards. (f) The setback for all buildings within a PUD from any abutting street line shall be thirty (30) feet for local streets and fifty(50)feet from railroad lines for collector or arterial streets, as designated in the comprehensive plan, except that in no case shall the setback be less than the height of the building up to a maximum of one hundred (100) feet. The setback for all buildings from exterior PUD lot lines not abutting a public street shall be thirty (30) feet Supp. No. 8 1200.4 ZONING § 20-505 except that in no case shall the setback be less than the height of the building up to a maximum of one hundred (100) feet. Building setbacks from internal public streets shall be determined by the city based on characteristics of the specific PUD. Parking lots and driving lanes shall be setback at least twenty (20) feet from all exterior lot lines of a PUD. The setback for parking structures including decks and ramps shall be thirty-five(35)feet from local streets and fifty(50)feet from all other street classifications except that in no case shall the setback be less than the height of the structure. Parking structure setbacks from external lot lines shall be fifty (50) feet or the height of the structure, whichever is greater where adjacent to residential property; thirty-five (35) feet when adjacent to nonresidential properties. Parking structures setbacks from internal public or private streets shall be determined by the city based on characteristics of the specific PUD. Where industrial uses abut developed or platted single-family lots outside the PUD, greater exterior building and parking setbacks may be required in order to provide effective screening. The city council shall make a determination regarding the adequacy of screening proposed by the applicant. Screening may include the use of natural topography or earth berming, existing and proposed plantings and other features such as roadways and wetlands which provide separation of uses. PUD's must be developed in compliance with buffer yard requirements established by the comprehensive plan. (g) More than one (1) building may be placed on one (1)platted or recorded lot in a PUD. (h) At the time PUD approval is sought from the city, all property to be included within a PUD shall be under unified ownership or control or subject to such legal restrictions or covenants as may be necessary to ensure compliance with the approved master development plan and final site and building plan. After approval, parcels may be sold to other parties without restriction,however, all parcels will remain subject to the PUD development contract that will be recorded in each chain-of-title. (i) Signs shall be restricted to those which are permitted in a sign plan approved by the city and shall be regulated by permanent covenants, established in the PUD Development Contract. (j) The requirements contained in article XXIII, General Supplemental Regulations, article XXIV, Off-street Parking and Loading, and article XXV, Landscaping and Tree Removal, may be applied by the city as it deems appropriate. (k) The uniqueness of each PUD required that specifications and standards for streets, utilities, public facilities and subdivisions may be subject to modification from the city ordinances ordinarily governing them. The city council may therefore approve streets, utilities, public facilities and land subdivisions which are not in compliance with usual specifications or ordinance requirements if it finds that strict adherence to such standards or requirements is not required to meet the intent of this [article) or to protect the health, safety or welfare of the residents of the PUD, the surrounding area or the city as a whole. Supp. No. 8 1200.5 § 20-505 CHANHASSEN CITY CODE (1) No building or other permit shall be issued for any work on property included within a proposed or approved PUD nor shall any work occur unless such work is in compliance with the proposed or approved PUD. (m) Buffer yards.The city comprehensive plan establishes a requirement for buffer yards. Buffer yards are to be established in areas indicated on the plan where higher intensity uses interface with low density uses. In these areas, a fifty-foot buffer yard is to be provided where the interface occurs along a public street,a one-hundred-foot buffer yard is required where the interface occurs on internal lot lines. The buffer yard is an additional setback requirement. It is to be cumulatively calculated with the required setbacks outlined above. The full obligation to provide the buffer yard shall be placed on the parcel containing the higher intensity use. The buffer yard is intended to provide additional physical separation and screening for the higher intensity use. As such, they will be required to be provided with a combination of berming, landscaping and/or tree preservation to maximize the buffering potential. To the extent deemed feasible by the city, new plantings shall be designed to require the minimum of maintenance,however,such maintenance as may be required to maintain consistency with the approved plan, shall be the obligation of the property owner. Buffer yards shall be covered by a permanently recorded conservation easement running in favor of the city. In instances where existing topography and/or vegetation provide buffering satisfactory to the city, or where quality site planning is achieved, the city may reduce buffer yard requirements by up to fifty (50) percent. The applicant shall have the full burden of demonstrating compliance with the standards herein. (Ord. No. 149, § 1, 6-24-91; Ord. No. 179, § 3, 11-23-92; Ord. No. 240, § 14, 7-24-95) Sec. 20-506. Standards and guidelines for single-family detached residential planned unit developments. (a) Intent. The use of planned unit developments for residential purposes should result in a reasonable and verifiable exchange between the city and the developer. The developer gains the potential for offering reduced lot sizes and flexibility in development standards which results in a combination of reduced development costs and improved marketing flexibility.At the same time, the city should be offered enhanced environmental sensitivity beyond normal ordinance requirements. Lot sizes should reflect the site's environmental limitations and opportunities and offer a range of housing pricing options. In addition, quality of development, as evidenced by landscaping, construction quality, provision of public/private open and recreational space, should also be enhanced. (b) Minimum lot size. The single-family residential PUD allows lot sizes down to a minimum of eleven thousand (11,000)square feet(excluding identified wetland areas from lot calculations). Average lot sizes for the entire PUD shall maintain a minimum area of fifteen thousand(15,000)square feet. The applicant must demonstrate that there are a mix of lot sizes Supp. No. 8 1200.6 ZONING § 20-506 consistent with local terrain conditions, preservation of natural features and open space and that lot sizes are consistent with average building footprints that will be concurrently ap- proved with the PUD. The applicant must demonstrate that each lot is able to accommodate a sixty-foot by forty-foot building pad and a twelve-foot by twelve-foot deck without intruding into any required setback area or protective easement.Each home must also have a minimum rear yard, thirty(30) feet deep. This area may not be encumbered by the required home/deck pads or by wetland/drainage easements.It may include areas with steep terrain or tree cover. (c) Minimum lot width at building setback: Ninety (90) feet. (d) Minimum lot depth: One hundred (100) feet. (e) Minimum setbacks: (1) PUD exterior: Thirty (30) feet*. (2) Front yard: Thirty(30) feet. (3) Rear yard: Thirty (30) feet. (4) Side yard: Ten (10) feet. * The thirty-foot front yard setback may be waived by the city council when it is demonstrated that environmental protection will be enhanced. In these instances, a minimum front yard setback of twenty (20) feet shall be maintained. Accessory buildings and structures—located adjacent to or behind principal structure a minimum of ten (10) feet from property line. (0 Protection and preservation of natural features. The applicant must demonstrate that the flexibility provided by the PUD is used to protect and preserve natural features such as tree stands,wetlands,ponds,and scenic views.These areas are to be permanently protected as public or private tracts or protected by permanently recorded easements. (g) Landscaping plan. An overall landscaping plan is required.The plan shall contain the following: (1) Boulevard plantings. Located in front yard areas these shall require a mix of over- story trees and other plantings consistent with the site. A minimum of over-story trees must be provided in each front yard. Well designed entrance monument is required. In place of mass grading for building pads and roads, stone or decorative block retaining walls shall be employed as required to preserve mature trees and the site's natural topography. (2) Exterior landscaping and double-fronted lots. Landscaped berms shall be provided to buffer the site and lots from major roadways, railroads, and more intensive uses. Similar measures shall be provided for double-fronted lots. Where necessary to ac- commodate this landscaping, additional lot depth may be required. (3) Rear yard. The rear yard shall contain at least two over-story trees. Preservation of existing trees having a diameter of at least six(6) inches at four (4) feet in height can Supp. No. 5 1200.7 § 20-506 CHANHASSEN CITY CODE be used to satisfy this requirement of the PUD and the plans should be developed to maximize tree preservation. (h) Architectural standards. The applicant should demonstrate that the PUD will provide for a high level of architectural design and building materials.While this requirement is not intended to minimize design flexibility,a set of architectural standards should be prepared for city approval.The primary purpose of this section is to assure the city that high quality design will be employed and that home construction can take place without variances or impact to adjoining lots. The PUD agreement should include the following: (1) Standards for exterior architectural treatments. (2) Prohibition against free standing garages may be required by the city when it is felt that unattached garages will be difficult to accommodate due to small lot sizes. If an attached garage is to be converted to living space at some time in the future, the applicant will have to demonstrate that there is sufficient room to accommodate a two car garage without variances to obtain a permit. (3) Guidelines regulating the placement of air conditioners, dog kennels, storage build- ings, and other accessory uses that could potentially impact adjoining parcels due to small lot sizes. (Ord. No. 179, § 1, 11-23-92) Sec. 20-507. Controls during construction and following completion. (a) The use of the land, the construction, modification or alteration of any buildings or structures in a PUD shall be governed by the final development plan. (b) After the certificate of occupancy has been issued, no changes shall be made in the approved final development plan for a PUD except: (1) Any minor extensions,alterations or modifications of existing buildings or structures may be authorized by the city planner if they are consistent with the purposes and intent of the final plan. No change authorized by this section may increase the bulk of any building structure by more that ten (10) percent. (2) Any building or structure that is totally or substantially destroyed may be recon- structed only in compliance with the final development plan unless an amendment to the final development plan is approved. (3) Changes in uses, any rearrangements of lots, blocks and building tracts, changes in the provisions of common open spaces, and all other changes to the approved final development plan may be made only after a public hearing conducted by the planning commission and upon final approval by the city council. Any changes shall be re- corded as amendments to the final development plan. (c) Major amendments to an approved master development plan may be approved by the city council after review by the planning commission. The notification and public hearing Supp. No. 5 1200.8 ZONING § 20-508 procedure for such amendment shall be the same as for approval of the original PUD.A major amendment is any amendment which: (1) Substantially alters the location of buildings, parking areas or roads; (2) Increases or decreases the number of residential dwelling units by more than five(5) percent; (3) Increases the gross floor area of nonresidential buildings by more than five(5)percent or increases the gross floor area of any individual building by more than ten (10) percent; (4) Deceases the amount of open space by more than five (5)percent or alters it in such a way as to change its original design or intended use; or (5) Creates noncompliance with any special condition attached to the approval of the master development plan. (Ord. No. 149, § 1, 6-24-91) Sec. 20-508. Standards and guidelines for single-family attached or cluster-home PUDs. (a) Generally. Single-family attached, cluster, zero lot line, and similar dwelling types shall only be allowed on sites designed for medium or high density residential uses by the City of Chanhassen Comprehensive Plan. (b) Minimum lot sizes. Minimum lot sizes down to five thousand(5,000)square feet may be allowed. There shall be no minimum lot size; however, in no case shall net density exceed guidelines established by the city comprehensive plan. (c) Setback standards/structures and parking: (1) PUD exterior: Fifty(50) feet. (2) Interior public right-of-way: Thirty (30) feet*. (3) Other setbacks: Established by PUD agreement. * The thirty-foot front yard setback may be waived by the city council when'it is demonstrated that environmental protection will be enhanced. In these instances, a minimum front yard setback of twenty(20) feet shall be maintained. (d) Protection and preservation of natural features. The applicant must demonstrate that the flexibility provided by the PUD is used to protect and preserve natural features such as tree stands, wetlands, ponds, and scenic views. These areas are to be permanently protected as public or private tracts or protected by permanently recorded easements. (e) Landscaping plan. An overall landscaping plan is required.The plan shall contain the following: (1) Boulevard plantings. Located in front yard areas these shall require a mix of over-story trees and other plantings consistent with the site. Landscaped berms shall be provided to screen the site from major roadways,railroads and more intensive land Supp. No. 8 1200.9 § 20-508 CHANHASSEN CITY CODE uses. Well designed entrance monument is required. In place of mass grading for building pads and roads, stone or decorative block retaining walls shall be employed as required to preserve mature trees and the site's natural topography. (2) Exterior landscaping and double-fronted lots. Landscaped berms shall be provided to buffer the site and lots from major roadways, railroads, and more intensive uses. Similar measures shall be provided for double-fronted lots. Where necessary to accommodate this landscaping, additional lot depth may be required. (3) Foundation and yard plantings. A minimum budget for foundation plants shall be established and approved by the city. As each parcel is developed in the PUD, the builder shall be required to install plant materials meeting or exceeding the required budget prior to issuance of certificate of occupancy or provide financial guarantees acceptable to the city. (4) Tree preservation. Tree preservation is a primary goal of the PUD. A detailed tree survey should be prepared during the design of the PUD and the plans should be developed to maximize tree preservation. (f) Architectural standards. The applicant should demonstrate that the PUD will provide for a high level of architectural design and building materials. While this requirement is not intended to minimize design flexibility, a set of architectural standards should be prepared for city approval. The primary purpose of this section is to assure the city that high quality design will be employed and that home construction can take place without variances or impact to adjoining lots. The PUD agreement should include the following: (1) Standards for exterior architectural treatments.

BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM TO: Planning Commission FROM: Cynthia Kirchoff, Planner I DATE: January 29, 1997 SUBJ: Off-Street Loading Areas - Issue Paper BACKGROUND The Chanhassen Annex of the United States Post Office is currently under construction in the Chanhassen Business Park. Two loading areas, located on the south side of the structure, fronting the rear yard of an adjacent single-family residential area. The issue of distance between loading areas and residential districts surfaced after residents expressed concern over the traffic and noise from the loading areas. Staff was directed to investigate loading dock locations in relation to residential districts. ISSUES Attached is the section of the Zoning Ordinance regulating loading areas. The Code states that loading areas must be "at least fifty (50) feet from the property line of any residentially designated property." The Comprehensive Plan requires a one hundred (100) foot bufferyard along interior lots between residential and non-residential uses. This bufferyard enables industrial uses, such as the post office, to be located adjacent to residential areas, yet provides protection for the residential district. The annex site plan indicates that there is a one hundred (100) foot buffer zone separating the industrial use from the residential. In addition, the loading areas are located approximately one hundred fifty (150) feet from the property line and all of the homes have the minimum standard thirty (30) foot rear yard setback. Thus, the loading areas will be located approximately two hundred eighty (280) feet from the adjacent homes. (There is also a ten (10) foot elevation change between the two uses.) Staff contacted a number of cities regarding minimum distance between loading areas and residential uses. The Cities of Andover, Chaska and Shakopee do not require a minimum Planning Commission January 29, 1997 Page 2 distance, while Minnetonka has an ordinance similar to ours. The most restrictive ordinance was from the City of Plymouth (copy attached). They require a 300 foot setback between residential districts and loading areas. Plymouth's ordinance may aim to protect the visual views of a residential neighborhood, rather than eliminate noise. Chanhassen's buffering requirements seem to provide the same result as Plymouth's from a visual impact standpoint. Chanhassen screens industrial parks by buffer zones and landscaping, while Plymouth requires an increased setback with less emphasis on a landscape buffer. Staff believes the site plan meets the requirements of the Plymouth Zoning Ordinance. The Planning Commission needs to define the goals of an ordinance amendment. If it is visual screening, we have the mechanism in our ordinance to provide it. If it is noise levels that we want to minimize, it will be difficult to specify a distance that will accomplish this goal, since many environmental factors such as weather, elevation, etc. play a role in noise divergence. RECOMMENDATION Based on the Planning Commission's input, staff will prepare any necessary code amendments. ATTACHMENTS 1. City of Chanhassen City Code, Section 20-1147 2.
