The Planning Commission was generally supportive of the proposed changes as they relate to implementing the Bluff Creek Overlay district. RECOMMENDED ACTION Staff is requesting the City Council review the proposed changes to the Planned Unit Development (PUD) ordinance and provide comments and direction on these changes. Please bring along your copy of Chapter 20 from your city code binder, which contains the entire PUD ordinance. SUMMARY Following are summaries of the changes being proposed: Article VIII. Planned Unit Development District Sec. 20-501 (9) (9) Use of traffic management and design techniques including the provision of transit and pedestrian linkages to reduce the potential for traffic conflicts. Improvements to area roads and intersections may be required as appropriate. Where appropriate, the use of transportation demand management strategies may be required within a project. *Staff is recommending this change to permit the city to require the use of tra~sportation demand management strategies such as flex time, preferential parking, {hr car pooling, etc., as part ora development, if, based on the use, the use could accommodate these strategies to mitigate traffic impacts.

Allowed Uses. Specific uses and performance standards for each PUD shall be delineated in a development plan. (1) Each PUD shall only be used for the use or uses for which the site is designated in the comprehensive plan, except *~'~'.,,,,, '~'~-,,. ~..j~" ......... ..,-., t~w,...,:~ "~-,t- compre v ............. J ........................................ ~. Specific uses and peffo~ance stand,ds for each P~ shall be delineated in a P~ development plan. *The city attorney has advised us that this section o£ the code may be in violation o[ state law, i.e., zoning must implement and be consistent with the comprehensive plan. (2) Where the site of a proposed PUD is designated for more than one (1) land use in the comprehensive plan, the 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. *For clarification purposes. Section 20-503 (a) (3) (3) The property is located in a transitional area between different land use categories or on a collector, minor ~ or principal arterial as defined in the comprehensive plan. *The city does not designate intermediate arterials in the comprehensive plan. Sec. 20-504. (b) and (c) (b) Site plan review under article II, division 6 of this Cede chapter shall be carried out for each non-single family or duplex principal structure;-that is proposed. *Municipal Code Corporation (MCC) recommendation. Todd Gerhardt November 24, 2003 PUD Ordinance Amendments Page 3 (c) PUD plans shall be coordinated with and in compliance with provisions of articles V, ~""~ °la;~ r~ .... ~, r~;o.4~,. ~.-,:~ VI, xxt~,~ r)~;o~' and m:t4de VII, c~.^~..~ c~ ....~.,, r~; o,,4~., of this chapter. *MCC recommendation. Section 20-505 (c) (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 net 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 areas will be evaluated using the items listed in section 20-506 or 20-508. 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 except as specified in policies supporting the city's affordable housing goals. *The city does not calculate density based on gross acreage. There is a conflict between the PUD ordinance and the Bluff Creek Overlay district. This and changes to section 20-508 should overcome those conflicts. The comprehensive plan permits density bonuses for the provision of affordable housing. Section 20-505 (d) of the Chanhassen City Code is amended to read: (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 o~dy-af~ contingent upon the developer and the city have entered into entering into an agreement ~ ensuring that ~-~ ~ ...... ,~ ~,~'; ..... the housing will be available to low and moderate income persons for a specific period of time. Todd Gerhardt November 24, 2003 PUD Ordinance Amendments Page 4 *Revisions proposed to clarify the intent of this requirement. Until the proiect is approved, the incentives can not be realized. Section 20-505 (i) (i) Signs shall be restricted to those which are permitted in the sign plan approved by the city and shall be regulated by permanent covenants or design standards established in the PUD Development Contract. *Language added for clarification purposes. Covenants are private agreements which are not enforced by the city. Design standards are approved by the city, incorporated in the Development Contract/PUD Agreement and used for compliance review. Sec. 20-505 (j) (J) The requirements contained in articles XXIII, r- ...... ~ ~ .... , ....,~ XXV, ~ o.a .... ; .... a w.== v ...... ~ of this Chapter may be applied by the city as it deems appropriate. *MCC recommendation. Section 20-506 (b) (b) Minimum lot size. The standard 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 square feet. The applicant must demonstrate that there are a mix of lot sizes and proposed housing types consistent with the local terrain conditions, preservation of natural features and open space and that lot sizes are consistent with average building footprints that will be concurrently approved with the PUD. The applicant must demonstrate that each lot is able to accommodate a sixty feet by r^,.,,, ~ t.,.;,a~ .... ,~ ,,,.,,4 ~ , .... ,,,~ ~ ~,, ~ ....,.,~ ~ a~.~. 4 000 square foot building envelop without intruding into any required setback area or protective easement. Each home must also have a minimum rear yard thiay (30) *The comprehensive plan encourages density at the upper end of the permitted density ranges. There has been extensive discussion regarding the use ora 60 ft. x 60ft. building pad. Staffis recommending that we include a minimum Todd Gerhardt November 24, 2003 PUD Ordinance Amendments Page 5 buildable area, which will accommodate house pads that are 80' x 50' or 75' x 54 ', etc., rather than a square pad. City Code, section 20-905, specifies minimum house sizes (960 sq. ft. for ramblers, 1,050 sq. ft. for split level, 600 sq. ~ft. split foyer, two story) or building footprint. Additionally, a two car garage is also required. Providing area for decks and porches would also increase the required building envelop. The minimum building envelop, based on these minimums, is approximately 2,000 sq. ft. The proposed building envelop would accommodate two times this area. Rear yard setbacks accommodate this open space. The city does not measure setbacks from the easement line, but rather from the property line, lake or wetland buffer edge. Wetland setbacks are larger than 30 feet; therefore, this language is unnecessary. Section 20-506 (g) (1) (1) Boulevard plantings. Located in front yard areas shall require a mix of over-story trees and other plantings consistent with the site. A minimum of one 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. *No quantity of overstory trees was specified. This language is consistent with the subdivision ordinance. Whether or not a development has an entrance monument should be left up to the project. Also, "well designed" is vague. Section 20-508 (a) (a) Generally. Single-family attached, cluster, zero lot line, townhouses and similar Wpe dwelling typeso..,~..~'~' ,,...j~"~-' may be allowed on sites designed for medium or high density residential uses by the City of Chanhassen Comprehensive Plan or on sites guided for residential - low density uses by the City of Chanhassen Comprehensive Plan which are located within the Bluff Creek Overlay district. *The use of the PUD for these types of developments are at the discretion of the city, not mandatory. The language change resolves some of the conflict between the PUD ordinance and the Bluff Creek Overlay district. The Planning Commission had been hesitant to incorporate this language city wide, but supported the idea within the Bluff Creek Overlay district. While staff would recommend that this be a zoning option city wide, at the discretion of the city, at a minimum the code should permit this flexibility within the Bluff Creek Overlay district. Todd Gerhardt November 24, 2003 PUD Ordinance Amendments Page 6 Section 20-508 (e) (1) (1) Boulevard plantings.

The plan shall include ~he following: a) In order to receive guidance in the design of a PUD prior to submission of a formal application, an applicant may submit a concept plan for review and comment by the planning commission and city council. Submission of a concept plan is optional but is highly recommended for large PUDs. In order for the review to be of most help to the applicant, the concept plan should contain such specific information as is suggested by the city. Generally, this information should include the following information appropriate to the type of development, e.g., commercial, industrial, or residential: Todd Gerhardt November 24, 2003 PUD Ordinance Amendments Page 7 1) approximate building areas, pedestrian ways and road locations; 2) height, bulk and square footage of buildings; 3) type, number or square footage or intensities of specific land uses; 4) number of dwelling units; 5) generalized development plan showing areas to be developed or preserved; and 6) staging and timing of the development. *These standards incorporate the concepts contained in the Minnetonka standards. Our intent at this stage of the development review is to understand the concept of the overall development, rather than the detailed information that will be worked out at the development stage, i.e., preliminary plat, and final ~tage, i.e., final plat approvals.
