LOCATION: SE of Crossroads Boulevard, 8941 Crossroads Boulevard (Lot 3, Block 1, Crossroads of Chanhassen). APPLICANT: PROPERTY OWNER: Kimley-Horn & Assoc., Inc. Kraus-Anderson Inc. Christian Jones Chrystal Seelhammer 767 Eustis Street, Suite 100 525 S.8th Street St. Paul, MN 55114 Minneapolis, MN 55404-1030 Christian.Jones@kimley-horn.com chrystal.seelhammer@krausanderson.com 763-251-1016 612-255-2345 PRESENT ZONING: Planned Unit Development, Mixed Use - PUD, Mixed Use 2040 LAND USE PLAN: Mixed Use ACREAGE: 0.79 acres DENSITY: N/A LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City has a relatively high level of discretion in approving amendments to PUDs because the City is acting in its legislative or policy-making capacity. A PUD amendment must be consistent with the City's Comprehensive Plan. The City's discretion in approving or denying a site plan is limited to whether or not the proposed project complies with Zoning Ordinance requirements. If it meets these standards, the City must then approve the site plan. This is a quasi-judicial decision. Notice of this public hearing has been mailed to all property owners within 500 feet. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 2 PROPOSAL/SUMMARY The request consists of two applications to facilitate the construction of an automotive facility. The request includes a Planned Unit Development amendment to existing standards, and Site Plan Approval for a 5,100 square foot automotive facility. The site is located southeast of Crossroads Boulevard. Access to the site will be gained off of Crossroads Boulevard. The site is zoned Planned Unit Development- Mixed Use. The following is a summary of the requests: 1. Planned Unit Development Amendment: The first request is to amend the permitted uses section to allow automotive repair shops. 2. Site Plan: The second request is for a site plan to construct a 5,100 square foot automotive repair shop. This use is not permitted under the PUD ordinance governing the site. If the requested amendment is not approved, the request for the site plan cannot proceed. The total permitted site coverage is 70 percent. The proposed development has a total hard coverage area of 43.8%. The design of the building is attractive and is proposed to be constructed of high-quality materials which include brick, concrete block and EIFS. The design of the building is harmonious with the surrounding buildings. Approval of this site plan is contingent upon amending the planned unit development to allow the use of automotive repair shops. Parking and nine garage doors have been screened properly. Access to the site is provided via internal curb cuts off of Crossroads Boulevard. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 3 APPLICABLE REGULATIONS Chapter 20, Article II, Division 2, Amendments Chapter 20, Article II, Division 6, Site Plan Review Chapter 20, Article VII, Planned Unit Development District Chapter 20, Article XXIII, Division 7, Design Standards for Commercial, Industrial, and Office- Institutional Developments BACKGROUND The Land Use Plan designates areas around the TH 101/TH 212 interchange as Mixed Use. This category has been established to accommodate either commercial or high-density residential developments. The high-density category, which includes units with a maximum net density of 16.0 units per acre, accommodates apartments and higher density condominium units, but would also permit the development of townhome-type units. The commercial use is intended to support or complement high-density residential development. Commercial uses may include convenience grocery stores, daycare facilities, etc., or those uses that meet the daily needs of the residents. The Planned Unit Development governing this development needs to be amended and standards for the use developed in order for the site plan to be considered and approved. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 4 Concept Plan On January 4, 2005, the Planning Commission reviewed and approved the Concept PUD for the site (not to be confused with site plan approval). This plan was later approved by City Council on January 24, 2005. This final concept layout reflected a residential component within the areas located north and south of Lake Susan Drive with the highest density concentration facing Highway 101. The portion of the site located south of Highway 212 consisted of a mix of commercial and residential uses. In that instance, the residential part encompassed the western portion of the site while the commercial part occupied the remainder of the site, and faced Highways 101, 212, and Lyman Boulevard. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 5 Development Plan On June 27, 2005, the City Council approved rezoning the property from Residential Single Family to Planned Unit Development-Mixed Use and adopted the Planned Unit Development ordinance that regulated and set standards for the development of this site including permitted uses, landscaping, setbacks, signage, building materials, architectural standards, parking, etc. On Februar y 27, 2006, the Chanhassen City Council approved a site plan for the construction of a three-story multi-family building containing 48 units, located northwest of the intersection of Highways 212/101 (north site). On January 24, 2008, the City requested the vacation of right-of-way along old Trunk Highway 101. A portion of the old highway occupies the westerly portion of the site. Development of the westerly portion of the site is contingent upon Minnesota Department of Transportation vacating the right-of-way. Amended Development Plan On March 10, 2008, the Chanhassen City Council approved the following: • Planned Unit Development amendment clarifying setbacks, signage, and retail building size. • Variance request to allow a 20-foot setback from Lyman Boulevard and a 20-foot setback from Highway 101. • Preliminary plat for Planning Case 2008-01 for Crossroads of Chanhassen. • Seven site plans consisting of a 5,300 square-foot convenience store with gas pumps and a 2,805 square-foot car wash (Building 4A), a multi-tenant building with an area of 11,000 square feet (Building 4B), a two-story multi- tenant building with a first floor area of 13,800 square feet and second floor area of 15,000 square feet (Building 4C), a one-story retail building with an area of 8,000 square feet (Building 4D), a 5,000 square-foot bank with drive-thru window (Building 4E), a 3,400 square -foot retail building (Building 4F), and a 10,000 square-foot Deli and Liquor Store (Building 4G). Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 6 On April 28, 2008, the City Council approved a final plat to subdivide 14.9 acres into three lots and one outlot - Crossroads of Chanhassen. On July 14 , 2008, the Chanhassen City Council granted final plat approval for Crossroads of Chanhassen 2nd Addition creating two lots and one outlot for the area of the development that is being reviewed as part of the development proposal for the daycare. That plat was never recorded. As part of the submittal, staff directed the applicant to conduct a traffic study to evaluate the trip generation and circulation of the site along with the impact to the intersection of Lyman Boulevard and Highway 101. A traffic study was performed by the applicant's engineer and reviewed by the City’s traffic consultant. Internally, the site has acceptable circulation. The only external site issue that was discovered is at the intersection of Lyman Boulevard and Crossroads Boulevard. Access spacing guidelines for Carver County do not allow a signal at this intersection. The possibility exists that the County could some day switch the access to Crossroads Boulevard to a right-in/right-out or block some of the turning movements. On March 26, 2012, the Chanhassen City Council approved a Planned Unit Developm ent amendment to the existing standards; Preliminary and Final Plat to subdivide 6.15 acres into one lot and one outlot (Crossroads of Chanhassen 2nd Addition); and Site Plan Approval for construction of a daycare facility (Primrose of Chanhassen). This request combined Buildings 4F and 4G into a single building. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 7 SITE PLAN In order to provide a better understanding of the overall development, staff will first review the site plan component , which in turn leads to the PUD amendment. The building must comply with the Development Design Standards for Chanhassen Gateway. A PUD is required to be developed to a higher quality than other projects. Site coverage is averaged over the entire development. This is permitted under the PUD ordinance (Section 20-505(e)). The total permitted site coverage is 70 percent. The proposed development has a total hard coverage area of 43.8%. The design of the 5,100 square foot building is attractive and is proposed to be constructed of high quality materials. They include br ick, EIFS accents, rough-face block, awnings, and glass. All elevations that can be viewed by the public have received equal attention. Shared parking is centrally located on the site. It is buffered from views by buildings and landscaping. Staff had multiple conversations with the applicant and explained that the proposed building should be unique yet be harmonious and complement the buildings on the block. The proposed design of the building, as well as the materials used, fit and complement existing structures. All 9 garage doors and parking lot are properly screened. Complimentary design elements include parapet walls, pronounced entryway and awnings around the windows to soften the look of the building. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 8 Below is a colored rendering with the proposed materials which will make the building architecturally a fitting element of the overall development. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 9 Parking is proposed along the southeast half of the site. Buffering/screening of the parking and the garage doors will be discussed in the L andscaping section of this report. The applicant is proposing a bench at the entrance of the building. The structure is proposed to be located on Lot 3, Block 1, Crossroads of Chanhassen. One monument sign is proposed along the northwest corner of the site. The sign must meet all sign ordinance requirements. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 10 The ordinance regulating this development limits signage to two elevations per building. The size of the individual letters may not exceed 30 inches and the sign must comply with ordinance. Wall signs are proposed above the three middle garage doors and the rear of the building. All signage (Monument and Wall signs) shall use individual dimension letters, at least one-half inch deep . The logo may not exceed 30% of the total sign area. All buildings within the development of Crossroads of Chanhassen must maintain a 20- foot setback from the right-of-way. To continue the vernacular perspective, the applicant will maintain this setback. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 11 LIGHTING The applicant has submitted a lighting and photometric plan. Light levels for site lighting shall be no more than one-half foot candle at the project perimeter property line. This does not apply to street lighting. All light fixtures must be consistent with the approved lighting plans. Staff is recommending that the lights be consistent with the approved fixtures in the development. Parking lot light fixtures may be 25 feet tall. All fixtures must be shielded. Monterey PARKING The ordinance requires auto repair shops to provide one parking space per 500 square feet of gross floor area. The entire Crossroads PUD shares parking spaces. The total required for the entire development is 247. The total proposed including the subject site is 278. ARCHITECTURAL COMPLIANCE Size, Portion and Placement Entries: The building has a pronounced entrance. Articulation: The building is part of a PUD. The buildings are intended to complement each other. The proposed building blends in and complements the architecture of the surrounding structures. It has unique features. All garage doors, parking and trash enclosure are properly screened. Signs: All signage must meet the sign criteria in the Planned Unit Development Design Standards for Chanhassen Gateway. W. 78th Street Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 12 Material and Detail High quality materials are being used on the building. Color The colors chosen for the building are earth tones. All materials are highly compatible with the existing buildings. Height and Roof Design The maximum building height in this PUD varies based on the use. The building meets the minimum set in the ordinance. The roofline is staggered, complements and is harmonious with the surrounding buildings. All rooftop equipment must be screened from views. Façade Transparency All facades viewed by the public contain more than 50 percent windows and/or doors except the southwest elevation. It is however properly screened. Loading Areas, Refuse Areas, Etc. The trash enclosure is located along the northeast corner of Lot 3, Block 1. The exterior material must be of the same exterior material as the building. Recycling space and other solid waste collection space should be contained within the same enclosure. SITE PLAN FINDINGS In evaluating a site plan and building plan, the City shall consider the development's compliance with the following: (1) Consistency with the elements and objectives of the City's development guides, including the Comprehensive Plan, official road mapping, and other plans that may be adopted; (2) Consistency with this division; (3) Preservation of the site in its natural state to the extent practicable by minimizing tree and soil removal and designing grade changes to be in keeping with the general appearance of the neighboring developed or developing areas; (4) Creation of a harmonious relationship of building and open space with natural site features and with existing and future buildings having a visual relationship to the development; Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 13 (5) Creation of a functional and harmonious design for structures and site features, with special attention to the following: a. An internal sense of order for the buildings and use on the site and provision of a desirable environment for occupants, visitors and general community; b. The amount and location of open space and landscaping; c. Materials, textures, colors and details of construction as an expression of the design concept and the compatibility of the same with adjacent and neighboring structures and uses; and d. Vehicular and pedestrian circulation, including walkways, interior drives and parking in terms of location and number of access points to the public streets, width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic and arrangement and amount of parking. (6) Protection of adjacent and neighboring properties through reasonable provision for surface water drainage, sound and sight buffers, preservation of views, light and air and those aspects of design not adequately covered by other regulations which may have substantial effects on neighboring land uses. Finding: The proposed development creates a harmonious relationship with existing and future buildings. It does provide a compatible visual relationship. Approval of this building is contingent upon approval of the permitted uses of the Planned Unit Development ordinance to allow auto repair shops with standards. PUD AMENDMENT Allow an Auto Repair Shop: The language in the PUD currently does not permit any type of auto repair facilities. Staff has been working with the applicant and has had numerous discussions to prepare a plan that can meet the intent of the ordinance. The proposed location is the farthest from any residential development but staff still has concerns. This type of establishment can generate loud noises from power tools. In the summer, all garage doors remain open and the sound can carry to surrounding areas. Should the City approve this amendment, staff recommends adding the following language under permitted uses: • Automotive Repair Shop on Lot 3, Block 1, with the following standards: o No unlicensed or inoperable vehicles shall be stored on-premises except in appropriately designed and screened storage areas. o All repair, assembly, disassembly and maintenance of vehicles shall occur Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 14 with closed building except minor maintenance including, but not limited to, tire inflation, addition oil and wiper replacement. o No public address system. o No sales, storage or display of used automobiles or other vehicles such as motorcycles, snowmobiles, or all-terrain vehicles. o Disposal of vehicle fluids shall comply with PCA regulations. o Facilities for the collection of waste oil must be provided. o All service/garage doors shall be screened. o The building architecture shall co mplement surrounding buildings. PLANNED UNIT DEVELOPMENT AMENDMENT FINDINGS The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse effects of the proposed amendment. The six (6) effects and our findings regarding them are: a) The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official City Comprehensive Plan. Finding: The site is guided Mixed U se (residential and neighborhood commercial). An auto repair shop can provide some convenience to neighboring properties. b) The proposed use is or will be compatible with the present and future land uses of the area. Finding: The proposed use can generate noise. The design and architecture of the proposed building is compatible with the surrounding buildings (design standards, landscaping, architecture, etc.). c) The proposed use conforms with all performance standards contained in the Zoning Ordinance. Finding: The proposed use will conform with all performance standards contained in the Zoning Ordinance such as design standards, signage, durable materials, uses, etc. d) The proposed use will not tend to or actually depreciate the area in which it is proposed. Finding: The proposed use is intended to meet the daily needs of the area. It could potentially add convenience to the homeowners in the area. e) The proposed use can be accommodated with existing public services and will not overburden the City's service capacity. Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 15 Finding: The site is located within the Municipal Urban Service Area. The proposed use can be accommodated with existing public services and will not overburden the City's service capacity. f) Traffic generation by the proposed use is within capabilities of streets serving the property. Finding: Traffic generation by the proposed use is within capabilities of streets serving the property. ACCESS Vehicular access to the site was originally provided from Crossroads Boulevard, a public street designed and built to Municipal State Aid Standards, during the construction of the original build-out of Crossroads of Chanhassen in 2008. The applicant is proposing to remove and restore the single access from Crossroads Boulevard in order to facilitate the proposed site plan layout. The removal and restoration of the original access will be required to meet the City’s Standard Specifications and Detail Plates and will require a traffic control plan for review and approval prior to commencement of construction activities on-site. The applicant is proposing that the building be located at the western edge of the site, angled parallel to Crossroads Boulevard, with the customer facing side of the building internal to the development, with parking located directly east of the building. With the proposed layout, vehicular access will be had from two driveways connected by the internal, private roads of the Crossroads of Chanhassen to the north and south of the site (see image below). Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 16 The south driveway appears to propose no extraordinary issues, however , the north driveway entrance may negatively impact vehicular traffic on Crossroads Boulevard due to the spacing from the intersection with Crossroads Boulevard. The applicant was required to provide analysis that the proposed north driveway location is adequately spaced as to not create adverse impacts to Crossroads Boulevard and that the largest design vehicle accessing the site could turn into the north driveway access fr om Crossroads Boulevard (from both northbound and southbound movements). The provided analysis proved the north access feasible. Crossroads Boulevard intersections with Lyman Boulevard, a Carver County road, and Highway 101, which is governed by MnDOT. Plans were provided to both parties for review, and any applicable comments and conditions set by Carver County and MnDOT must be addressed. The applicant will be required to provide a brief traffic memo identifying changes to the PUD trip generation leve ls, traffic patterns, and impacts to the County and MnDOT intersections compared to the original PUD plan and traffic study as the site was not analyzed based on the intended use (previous trip generations were based on a drive-thru bank). EASEMENTS A 10-foot public drainage and utility easement along the western portion of the property was recorded with the original plat from 2008 for Crossroads of Chanhassen. As all utilities and Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 17 roads within the development are privately owned and maintained and covered under cross access agreements or private easements, no additional public easements are required from the proposed site plan. It is recommended that the applicant verify that all private easements and cross access agreements and their subsequent conditions are adhered to prior to construction. GRADING The first phase of the Crossroads of Chanhassen PUD completed mass grading of the site to achieve the relative elevations required for the site to be built-out. As such, the applicant is not proposing mass grading or major alterations to existing elevations of the site. However, as improvements are installed (underground and surface stormwater facilities, installation of utilities, paving and construction of parking areas, building pads, etc.) the site will expose soils and will be required to meet all erosion control measures as addressed under “Drainage and Erosion Control” of this report. DRAINAGE AND EROSION CONTROL The proposed development will exceed 5,000 square feet of land area disturbance, and as such, will require an erosion and sediment control plan submitted to the City. This shall be a stand along document that includes all required information listed in Chapter 19-145(a)(2) of the Chanhassen City Code. The applicant appears to have provided a sufficient erosion and sediment control plan, with minor amendments required. All erosion control shall be installed and inspected prior to initiation of site grading activities. The proposed erosion control measures and BMPs appear adequate. However, if at any time during the construction of the site prior to final stabilization, these measures are found to be inadequate, additional BMPs will be required to meet the NPDES permit. All exposed soil areas shall have temporary erosion protection or permanent cover year round. In the event that dewatering is needed, the city inspector shall be contacted prior to any dewatering activities. STORMWATER MANAGEMENT The proposed development consists of a new automotive repair building, parking lot, associated utilities, and an underground and surface stormwater management BMPs. The 0.80-acre site is subject to the requirements of the Riley Purgatory Bluff Creek Watershed District (RPBCWD). The existing site consists of a vacant grass area with slopes of 1% to 4% encompassing much of the site. Prior to the proposed development, stormwater from the northeastern portion of the site flows to an existing inlet to the north of the site along an internal road for the overall development and is conveyed to the public storm sewer system. The western and northwestern portion of the site flows west to Crossroads Boulevard, a paved public street. Stormwater from the eastern and southern portion of the site flows to an existing area drain inlet on the south portion of the site and connects to the existing underground stormwater system. After development, site improvements will maintain existing drainage patterns. Stormwater runoff from a portion of the roof and a majority of the paved parking surface will discharge to a proposed underground stormwater infiltration system, noted on the plans as BMP #2. The Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 18 underground stormwater infiltration system is proposed to be perforated 36” pipe. Overflow from this BMP is routed to the existing underground storm sewer network. Stormwater runoff from the western portion of the roof will discharge to an infiltration basin, noted on the plans as BMP #1, on the west side of the proposed building. Overflow from this BMP is routed to an existing catch basin within Crossroads Boulevard. These BMPs appear to be adequate to treat stormwater runoff from the site. All stormwater from the site eventually runs to MnDOTs BraeBurn Pond, which was constructed with the off ramp of Highway 212. The applicant has evaluated that the impervious surface from this site will not inundate or negatively impact the downstream MnDOT facility based on new rainfall requirements (TP-40 vs NOAA Atlas 14). Article VII, Chapter 19 of City Code describes the required stormwater management development standards. Section 19-141 states that “these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features.” These standards include abstraction of runoff and water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). In addition, the project will need a permit from the Riley Purgatory Bluff Creek Watershed District prior to beginning construction activities. The RPBCWD provided a memorandum outlining the need for a permit and listed potential District rules that this project might meet. These rules are not considered exhaustive of all potential RPBCWD rules or provisions that may apply. The City encourages the applicant to work directly with RPBCWD to obtain the necessary approvals and permit. UTILITIES (SANITARY/WATER) The developer of the Crossroads of Chanhassen installed private sanitary sewer and water main throughout the development during the 2008 build-out of the PUD, and the proposed site has adequate sanitary and water services which will be had from these private utility extensions. The applicant is proposing to abandon an existing water service stub located near the southwest corner and southeast corner of the site. These service laterals were installed with the Crossroads of Chanhassen and the proposed abandonment appears to be due to the proposed site layout. Abandonment of the existing water services shall meet the City’s Standard Specifications and Detail Plates (Specifications). The applicant is proposing to service the site with 1” PVC water service and a 6” PVC sanitary sewer service to be connected directly to the existing 8” stub. As required by Ordinance, the subject development is required to pay sanitary sewer and water hookup charges. These fees are based on the number of SAC units assigned by the Met Council and are due at the time of building permit issuance. The 2020 rates are $2,302.00/unit and $7,974.00/unit for sanitary sewer and water, respectively. LANDSCAPING AND TREE PRESERVATION Minimum requirements for landscaping at the proposed development include 1,484 sq. ft. of landscaped area around the parking lot, 3 landscape islands or peninsulas, and 6 trees for the Christian Brothers Automotive Planning Case No. 2020-21 December 1, 2020 Page 19 parking lot. The applicant’s proposed as compared to the requirements for landscape area and parking lot trees is shown in the following table. Required Proposed Vehicular use landscape area 1,484 sq. ft. 1,484 sq. ft.

The proposed development is within the Crossroads of Chanhassen PUD which was approved in 2008. The two lots east of the proposed site have been previously developed as retail and a gas station/convenience store, a child care facility is located to the south and west of the proposed site, and the rest of the PUD is currently undeveloped. Proposed Concept Plan & Development Stage Christian Brothers Automotive is proposing an amendment to the existing planned unit development (PUD). The PUD is designated as mixed use PUD including neighborhood commercial, office and residential. Christian Brothers provides light automotive repair and the scope of repairs provided by Christian Brothers has been included within the submittal package. Overnight parking only occurs when customers have a conflict retrieving their vehicle during business hours or to drop off their vehicles. Long term exterior storage is not permitted at Christian Brothers Automotive. Consultants: Civil Engineer – Christian Jones, Brandon R.

Gas, communications, and electric utilities are provided to the west along Crossroads Boulevard. The proposed building is to be located at the western edge of the site angled parallel to Crossroads Boulevard, with the customer facing side of the building internal to the development. The surface parking will be located directly east of the building. Access is proposed to be east of the building and at both the north and south side of the parking lot, with two proposed driveways connecting the internal roads of the Crossroads of Chanhassen. The existing site is currently vegetated with no impervious area; the proposed site will be comprised of approximately 70% impervious area. Above ground and underground stormwat er management will be provided adhering to City and Watershed treatment and rate control requirements. Architecture Architectural elevations and site photometric plans are provided within the submission. The proposed building is to be constructed of primarily brick and limestone. The trash enclosure is also to be constructed in materials similar to the building and will have gates to screen the trash from the public right-of-way. Landscape Architecture A landscape plan is included within the submission to comply with the city code. Trees, shrubs, and other plantings will complement the site. Christian Brothers Automotive is seeking a landscape variance for screening of the vehicular area.

Please reference the Public Works Development Review Process document on the County’s website for detailed instructions. The County assumes compliance with State Statute 505.03 Subdivision 2 regarding road authority review. Consistent with the County Comprehensive Plan and County Codes, the following are comments and recommended conditions of approval and potential requirements for any necessary permits to be issued for the project: 1. Impacts to County Right of Way and Access to County Highways a. The subject site is not adjacent to County right of way and no direct access to County Highways is proposed. Additional County review and approval will be required if this condition changes. 2. Traffic Impacts a. It is recommended to provide a brief traffic memo identifying changes to PUD trip generation levels, traffic patterns, or impacts to the County highway intersections of CSAH 101 (Great Plains Blvd.)/Crossroads Blvd. and CSAH 18 (Lyman Blvd.)/Crossroads Blvd. compared to the original PUD plan and traffic study. The memo should note the expected level of service at these intersections and any findings that impact future traffic operation needs. 3. Required Permits a. Prior to any work affecting or on County highways or in County right of way (none currently proposed), the applicant shall coordinate plans with the County Engineer and obtain a Utility or Excavating/Filling/Grading Permit(s) from Carver County Public Works: (http://www.co.carver.mn.us/how-do-i/apply-for/a-permit). Final details of locations, grades, and profiles affecting County roads as well as any utility connections will need to be reviewed and approved prior to any permits. b. Any damages, modifications, or changes incurred on County highways from current or approved conditions will need to remedied or updated at development expense, including costs incurred by the County. These are the County’s comments at this time.

Box 147 Chanhassen, MN 55317 RE: Kimley Horn and Associates- Case No. 2020-21 Dear Ms. Al-Jaff, Kimley-Horn has reviewed the comments provided by City of Chanhassen, dated September 30, 2020, and has modified the plans accordingly. The comments and responses are listed below. Responses to comments are in bold italics. ENVIRONMENTAL RESOURCES 1. The applicant shall plant a minimum of six trees in the parking lot. Two trees have been provided within the parking lot islands to provide screening of the garage doors as well as 5 additional trees throughout the rest of the site. In addition to the two trees provided in the parking lot, and to provide additional screening, tall shrubs have been placed along the east property line and southwest of the parking lot to screen the parking area and service garage doors. Please refer to Landscape Plan for details. 2. The applicant shall meet the minimum 10’ interior width for all landscaped islands and peninsulas. Island widths have been revised to provide a minimum interior wid th of 10’. Please refer to Sheet C2.0. 3. The applicant shall include landscaping along the eastern property line that screens the parking area and garage door. Tall shrub landscaping has been provided along the east property line to provide screening of the garage service doors. Please refer to Sheet LP-1. 4. The applicant shall include a minimum of two over story trees to be planted along Crossroads Boulevard. Two over story trees have been provided along Crossroads Boulevard. Please refer to Sheet LP-1. 5. All existing trees on site to be saved during construction shall be protected at all times by tree preservation fencing. Trees that are damaged or dead will be replaced. Existing trees on site and within the limits of disturbance are to be protected in place through the duration of construction. Please refer to Sheet C1.0 for tree protection location and Sheet C1.1 for tree protection detail. Page 2 ENGINEERING 1. The applicant shall provide a traffic control plan for review and approval for the remo val and restoration of the original access had from Crossroads Boulevard prior to commencement of construction activities on-site. Traffic control plans shall be prepared by the Contractor for work completed within the public right-of-way. The Contractor shall submit a traffic control plan to the City for review prior to construction activity onsite. 2. The applicant shall provide analysis that the proposed north driveway location is adequately spaced as to not create adverse impacts to Crossroads Boulevard and that the largest design vehicle accessing the site can turn into the north driveway access from Crossroads Boulevard (from both northbound and southbound movements) prior to permits being issued. The northern access to the proposed project is aligned with the curb line with the existing gas station, and is spaced approximately 55 feet from Crossroads Blvd. Vehicles entering the site will have a free right turn movement into the site, so impacts on Crossroads Blvd from cars entering the site shall be minimal. The preliminary PUD plans show a direct access to Crossroads Blvd, to us direct access to Crossroads Blvd would have a greater impact to traffic flow on Crossroad Blvd. By moving the access to the north side of the property, vehicles will only enter and exit the development in three locations, allowing Crossroads Blvd to have a better traffic flow pattern. Additionally, by removing the parking from the southerly access road that was shown in Preliminary Plans, the southern drive to Crossroads Blvd functions much better as well. A vehicle access exhibit (EX-1) included in the proposed civil documents is provided displaying the vehicle access route for a design vehicle entering the site from Crossroads Boulevard. 3. The water service lateral located on the existing condition survey near the southeast corner of the site shall be abandoned by removing the stub to the main and capping per City Standards. Noted. The existing water service on the southeast corner of the property shall be removed to the main and capped per City Standards and Specification. Please refer to Sheet C1.0. 4. The water service lateral shall meet current City specifications, which shall include a 1” plastic service lateral. Noted. The proposed water service lateral shall be a 1” plastic service lateral per City Standard Plate 1005. Please refer to Sheet C4.0 and C4.1. 5. The sanitary service lateral shall connect to the existing manhole via a core and boot connec tion. Noted. A note on the utility plan has been added to direct the contractor on how to make this connection. 6. The applicant shall pay the appropriate sanitary sewer and water trunk hook-up fees at the time of building permit issuance. These fees are based on the number of SAC units assigned by the Met Council and are due at the time of building permit issuance. The 2020 rates are $2,302.00/unit and $7,974.00/unit for sanitary sewer and water, respectively. Noted. Applicable fees shall be paid prior to permit issuance. CONSTRUCTION PLANS 1.

The 0.80- acre site is located at 8941 Crossroads Boulevard in Chanhassen, MN, and is part of the Crossroads of Chanhassen planned unit development. The Site is subject to the requirements of the Riley-Purgatory- Bluff Creek Watershed District (furthermore referred to as RPBCWD). This report is to provide information for the pre-development drainage conditions, the post-development drainage conditions, and the stormwater management system(s) designed to meet the RPBCWD storm water requirements for the proposed development. Kimley-Horn has analyzed the drainage conditions of the site and provides computations for applicable RPBCWD stormwater requirements in this report. The analysis of the pre-development and post- development drainage models was completed using HydroCAD, Version 10.00, a computer aided design system for modeling the hydrology and hydraulics of stormwater runoff. These calculations are largely based on the hydrology techniques developed by the Soil Conservation Service (SCS/NRCS), combined with other hydrology and hydraulics calculations. All calculations, hydrographs, and drainage area maps are provided in the appendix of this report. 2.0 Pre-development Conditions The existing site consists of a vacant grass area, with slopes of 1% to 4% encompassing much of the Site. Although a Geotechnical report has not been completed for this site, soil conditions referenced from the USDA NRCS Web Soil Survey outline a large majority of the site being encompassed by sandy loam and loamy sand from the surface to a depth of at least 6’ below finished grade. Based on this data, an infiltration rate of 0.80 in/hr is assumed for design calculations. In the existing conditions, stormwater from the northeastern portion of the site (V-DA-2) flows to an existing inlet to the north of the site along an internal road for the overall development and is conveyed to the public storm sewer system. The western and northwestern portion of the Site (V-DA-1 and V- DA-3) flows west to Crossroads Boulevard, a paved public street. Stormwater from the eastern and southern portion of the site (V-DA-4) flows to an existing area drain inlet on the south portion of the site and connects to the existing public underground stormwater system offsite. A summary of the pervious and impervious coverage for existing conditions is included below: • Drainage Area = 0.80 acres o Existing Pervious Area = 0.79 acres (99%) o Existing Impervious Area = 0.01 acres (1%) o Weighted Curve Number (CN) = 61 3.0 Post-development Conditions The proposed development consists of an approximately 5,100 sf commercial building, concrete parking lot, utilities, underground and above-ground stormwater management areas, and landscaping. Site improvements will maintain existing drainage patterns. Christian Brothers Automotive - Stormwater Report Page 5 Chanhassen, MN Stormwater runoff from a portion of the roof and majority of the paved parking surface will discharge to a proposed underground stormwater infiltration system, BMP #2. The underground stormwater infiltration system is proposed to be perforated 36” pipe. Overflow from this BMP is routed to the existing underground storm sewer network. Stormwater runoff from the western portion of the roof will discharge to an infiltration basin (BMP #1) on the west side of the proposed building. Overflow from this BMP is routed to an existing catch basin within Crossroads Boulevard. A summary of the pervious and impervious coverage for proposed conditions is included below. • Drainage Area = 0.80 acres o Proposed Pervious Area = 0.25 acres (31%) o Proposed Impervious Area = 0.55 acres (69%) o Weighted Curve Number (CN) = 87 4.0 Rate Attenuation Summary The Riley-Purgatory-Bluff Creek Watershed District requires that sites limit peak flow rates from the site in the 2-, 10-, and 100-year, 24-hour nested rainfall events and the 100-year, 10-day snowmelt event using Atlas 14 precipitation depths and storm distributions. In addition to City requirements, the site must maintain existing drainage patterns including volume and rate of existing runoff. The proposed development achieves this requirement as outlined in the table below: Table 1: Rate Attenuation – Atlas 14 Table 2: Rate Attenuation – TP-40 2 Year (2.84 in.) 10 Year (4.20 in.) 100 Year (7.18 in.) 100 Year, 10-day Snow Melt Event (7.30 in.)

It is our understanding the existing MnDOT drainage facility was originally designed utilizing Technical Paper-40 rainfall data administered by the National Oceanic and Atmospheric Administration. The pre-development runoff rate utilizing TP-40 rainfall intensity data, as shown in Table 2 above, shows the existing runoff rate from the site is 2.51 CFS. The post- development condition is assessed using the Atlas-14 distribution, where the 100-year rainfall event for the total site is 2.41 CFS. The proposed post-development runoff rate utilizing the TP-40 rainfall intensity data yields a runoff rate of 0.65 CFS, which is lower than the existing MNDOT drainage facility was designed for. The proposed runoff rate utilizing the Atlas-14 analysis, as well as the TP- 40, is lower than the existing conditions TP-40 runoff rates, as shown above. 5.0 Volume Reduction Summary The Riley-Purgatory-Bluff Creek Watershed District requires applicants provide onsite retention of 1.1 inches over the proposed impervious surface of the Site. Based on the proposed plans the required onsite retention is met based on the following: Table 3: Volume Reduction Proposed Impervious Area (Reconstructed and New) 0.55 AC Treatment Depth Required 1.1 Inches Required Infiltration Volume 2,196 CF Provided Infiltration Volume BMP #1: 2,470 CF BMP #2: 5,669 CF 8,139 CF TOTAL 6.0 Water Quality Summary The Riley-Purgatory-Bluff Creek Watershed District requires removal of 60% of the total phosphorus (TP) and 90% of the total suspended solids (TSS). Watershed requirements will be achieved through the use of infiltration in BMP #1 and BMP #2. All BMPs systems are required to provide water quality volume below the lowest flow outlet and provide draw down within 48 hours. An infiltration rate of 0.8 in/hr was used per the USDA Web Soil Survey information and Minnesota Stormwater Manual recommendations. Based on this infiltration rate, the maximum allowable infiltration for these systems is based on a ponding depth of 3.2 feet above the bottom of the system. BMP #1 proposes a ponding depth of 1.70 feet, which is within the required limit. BMP #2 proposed a ponding depth of 2.60 feet, which is within the required limit. In addition to Results of the Minimal Impact Design Standards (MIDS) analysis for the site is shown in the Summary below. These results show that BMP #1 and BMP#2 increase the site’s removal efficiency of TP and TSS when compared to existing conditions, which is consistent with requirements of the RPBC Watershed District. A full analysis is provided in Appendix 3. Water Quality Calculations.

Outlet Structure Maintenance The Owner will be responsible for outlet structure maintenance. Periodically, the low flow orifice may clog with debris. Debris should be removed and disposed of outside of the facility limits. Debris & Litter Debris and litter should be removed on a monthly basis to maintain appearance and functionality of the facility. Christian Brothers Automotive Chanhassen, MN STORMWATER MANAGEMENT OPERATION & MAINTENANCE PLAN - 3 Plant Maintenance The vegetation type and amount are important to ensure that the facility operates correctly. Proper vegetation maintenance includes watering plants during dry periods, re-mulching void areas, treating diseased trees and shrubs and mowing turf areas. MAINTENANCE OF UNDERGROUND ADS INFILTRATION SYSTEM Regular inspection and maintenance are critical to the effective operation of the underground filtration systems. It is the responsibility of the property owner to maintain all stormwater BMPs in accordance with the minimum design standards and other guidance provided in this manual. See Appendix A for ADS Stormtech guidelines for additional operation and maintenance procedures. Inspection Schedule One inspection form shall be completed for the underground detention system on a monthly or annual basis as specified on the checklist. Erosion The soil and mulch on the property shall be inspected for eroded areas. Eroded areas shall be filled with soil or mulch and vegetated. In the event that erosion persists in a particular area, compacted aggregate shall be used to further stabilize the slope and to mitigate future erosion. Sediment Accumulation & Clogging Sediment accumulation within the facility may reduce the infiltration capacity and impair proper performance of the facility. The facility shall be inspected for accumulation of sediment as part of the inspection. Excessive sediment accumulation shall be removed. Outlet Structure Maintenance The Owner will be responsible for outlet structure maintenance. Periodically, the outlet pipe may clog with debris. Debris should be removed and appropriately disposed of off- site. Standing Water/Pipe Inspection Visual inspection of the pipe chamber system shall occur once per year until a cleaning schedule can be established based on the amount of sediment that is left within the system. Prior to entry into the underground system, the user shall follow all applicable OSHA and local safety regulations. Inspections should occur at least 2-3 days after the most recent rainfall event. The system should be visually inspected at all manhole locations. Utilizing a sediment pole, measure and document the amount of silt at each manhole locations. Inspect each pipe opening to ensure that the silt level or any foreign objects are not blocking the pipes. The sediment level should be measured and recorded during the inspection process. Christian Brothers Automotive Chanhassen, MN STORMWATER MANAGEMENT OPERATION & MAINTENANCE PLAN - 4 The system should be cleaned once the available depth of sediment is 6” above the bottom of the chambers. Cleaning of the system can be done by a vacuum truck every 3-5 years based on actual sediment accumulation or as needed to remain below maximum sediment volume per manufacturer’s recommendations. If the facility has standing water more than 48 hours after a rain event, the system shall be cleaned. To clean, remove the manhole cover at the top of the system and lower a vacuum hose into one of the rows of the pipe system. Open the manhole at the opposite end of the system and use sewer jetting equipment to force water in the same row from one end of the pipe system row to the opposite side. Place the vacuum hose and the sewer jetting equipment in the next row and repeat the process. Inspection and Maintenance (per manufacturer recommendations) Inspect isolator row for sediment. If sediment is at or above 3”, clean out isolator row using the Jetvac process, vacuum structure sump as required. Replace all covers, grates, filters, and lids; record observations and actions. Inspect and clean basins and manholes upstream of the Stormtech system. Refer to manufacturer for complete inspection and maintenance requirements and recommendations. Inspect every 6 months during the first year of operation. Adjust the inspection interval based on previous observations of sediment accumulation and high-water elevations. Conduct jetting and vactoring annually or when inspection shows that maintenance is necessary. MAINTENANCE OF SUMPED PRETREATMENT MANHOLE Remove sediment from the manhole and pretreatment device by using a vacuum truck. Visual inspection to ensure no pipe blockage should occur at the time of cleaning. Prior to entry into the storm sewer manhole, the user shall follow all applicable OSHA and local safety regulations. The pretreatment manholes shall be inspected at least three times during the first two years to inspect the amount accumulated sediment and screen/baffle clogging over the first two years following installation. From the frequent inspections a structure specific maintenance program can be developed. Sediment shall be cleaned once one foot of sediment has accumulated in the manhole sumps. At a minimum the structures containing pretreatment device shall be fully cleaned once a year.

Individuals using this information should make their own decisions as to suitability of this guideline for their individual projects and adjust accordingly. Introduction A retention/detention system is comprised of a series of pipes and fittings that form an underground storage area, which retains or detains storm water runoff from a given area. As sediment and debris settle out of the detained stormwater, build up occurs that requires the system to be regularly inspected and cleaned in order for the system to perform as originally designed. The following provides the available fittings and guidelines for inspection and maintenance of an HDPE underground storage system. System Accessories and Fittings Concentric Reducers Concentric Reducers are fittings that transition between two pipes, either in line with one another or at perpendicular angles. The centerlines of the two pipes are at the same elevation. When a concentric reducer is used to connect the manifold pipe to the lateral pipes, most debris will be trapped in the manifold pipe. SIDE VIEW SECTION VIEWSIDE VIEW SECTION VIEW Eccentric Reducers Eccentric Reducers are fittings that transition between two pipes, either in line with one another or at perpendicular angles. The inverts of the two pipes are at the same elevations. When an eccentric reducer is used to connect the manifold pipe to the lateral pipes, most debris will follow the flow of the storm water into the lateral pipes. SIDE VIEW SECTION VIEW SIDE VIEW SECTION VIEW 2 4640 TRUEMAN BLVD. HILLIARD, OH 43026. (800) 821-6710 – www.ads-pipe.com Riser Each retention/detention system typically has risers strategically placed for maintenance and inspection of the system. These risers are typically 24” in diameter or larger and are placed on the manifold fittings. Cleanouts Cleanout ports are usually 4-, 6-, or 8-in diameter pipe and are placed on the manifold fittings. They are used for entrance of a pipe from a vacuum truck or a water-jetting device. For a complete listing of available fittings and components please refer to the ADS Fittings Manual. Maintenance Overview of a Retention/Detention System Maintaining a clean and obstruction-free retention/detention system helps to ensure the system performs the intended function of the primary design. Build up of debris may obstruct flow through the laterals in a retention system or block the entranceway of the outlet pipe in a detention system. This may result in ineffective operation or complete failure of the system . Additionally, surrounding areas may potentially run the risk of damage due to flooding or other similar issues. Inspection/Maintenance Frequency All retention/detention systems must be cleaned and maintained. Underground systems may be maintained more cost effectively if these simple guidelines are followed. Inspection should be performed at a minimum of once per year. Cleaning should be done at the discretion of individuals responsible to maintain proper storage and flow. While maintenance can generally be performed year round, it should be scheduled during a relatively dry season. Pre-Inspection A post-installation inspection should be performed to allow the owner to measure the invert prior to accumulation of sediment. This survey will allow the monitoring of sediment build-up without requiring access to the retention/detention system. The following is the recommended procedure for pre-inspections: 1) Locate the riser section or cleanouts of the retention/detention system. The riser will typically be 24” in diameter or larger and the cleanouts are usually 4”, 6” or 8” in diameter. 2) Remove the lid of the riser or clean outs. 3) Insert a measuring device into the opening and make note to a point of reference on the stick or string. (This is done so that sediment build up can be determined in the future without having to enter the system.) RISER CROSS-SECTION VIEW CLEANOUT CROSS-SECTION VIEW 3 4640 TRUEMAN BLVD. HILLIARD, OH 43026. (800) 821-6710 – www.ads-pipe.com Inspection/Maintenance A retention/detention system should be inspected at a minimum of one time a year or after major rain events if necessary. The following is the recommended procedure to inspect system in service: 1) Locate the riser section of the retention/detention system. The riser will typically be 24” in diameter or larger. 2) Remove the lid from the riser. 3) Measure the sediment buildup at each riser and cleanout location. Only certified confined space entry personnel having appropriate equipment should be permitted to enter the retention/detention System. 4) Inspect each manifold, all laterals, and outlet pipes for sediment build up, obstructions, or other problems. Obstructions should be removed at this time. 5) If measured sediment build up is between 5% - 20% of the pipe diameter, cleaning should be considered; if sediment build up exceeds 20%, cleaning should be performed at the earliest opportunity. A thorough cleaning of the system (manifolds and laterals) shall be performed by either manual methods or by a vacuum truck. 1 :12 The purchaser agrees to hold the seller harmless against any cause for action for damages which may occur as a result of drilling for piers and foundations, including but not limited to sewer, gas lines or any underground obstacles which the purchaser or others may deem valuable. 8941 Crossroads Blvd Chanhassen MN 55317 Connie Keck JW Vx1100488-R2 07/21/20 10/16/20 This design and engineering is submitted as our proposal, and the right to use or exhibit in any form, is not authorized without written permission by Vixxo.

A rezoning must be consistent with the city’s Comprehensive Plan. The city’s discretion in approving or denying a Preliminary Plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi-judicial decision. PROPOSED MOTION: “The Chanhassen Planning Commission recommends approval of the rezoning from Rural Residential District (RR) to Single Family Residential (RSF), and Subdivision approval to create four lots and one outlot with a variance for the use of a private street to provide direct access to the four lots and a variance to use the 33-foot right-of-way and 24-foot street section subject to the conditions of approval in the staff report And Adoption of the Findings of Fact and Recommendation.” Planning Commission Deer Haven December 1, 2020 Page 2 The City’s discretion in approving or denying a variance is limited to whether or not the proposed project meets the standards in the Subdivision Ordinances for variances. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. Notice of this public hearing has been mailed to all property owners within 500 feet. PROPOSAL/SUMMARY The applicant is requesting the rezoning of property from Rural Residential (RR) to Single- Family Residential (RSF) and subdivision of 2.8 acres into four single-family lots and one outlot with variances for public right-of-way width, local street width and the use of a private street. APPLICABLE REGULATIONS Chapter 18, Subdivisions Chapter 20, Article II, Division 2. Amendments Chapter 20, Article XII, RSF Single-Family Residential District BACKGROUND The house was built in 2003. The property is not part of any recorded subdivision, Registered Land Survey or other approved plat. EXISTING CONDITIONS The site is 2.81 acres and currently has an existing single-family residence that is being proposed to remain with the development of the subdivision. The applicant provided an Existing Conditions Survey which is used to supplement all construction plans and designs that is generally in conformance with the requirements of Sec. 18-40. However, required information that was not provided includes: location of buildings and easements to a distance 150 feet beyond the subdivision boundaries; topographic data 100 feet beyond the property boundary, with associated contours; boundary lines of adjoining platted or subdivided land, within 150 feet, identified by name and ownership, etc. In order to show the proper extents, the scale of the survey may need to be increased, which is also typical of all construction plans provided. The applicant shall submit an updated survey upon submittal of final plat and final construction plans illustrating all the requirements of Sec. 18- 40. Furthermore, an accurate soils report indicating soil conditions, permeability and slope shall be provided upon submittal of final plat (Sec. 18-40.(2)h.). The soils report shall include boring logs for key areas including along the proposed alignment of the private street and near areas proposed for stormwater infiltration. SITE CONSTRAINTS Wetland Protection Planning Commission Deer Haven December 1, 2020 Page 3 There is not a wetland located on the property. Bluff Protection There are no bluffs on the property. Though there is a small area of steep slopes, it does not meet the City’s definition of a bluff. Shoreland Management The property is not located within a shoreland protection district. Floodplain Overlay This property is not within a floodplain. SURROUNDING ZONING AND USES The properties to the north, south, and east of the proposed development are zoned Single-Family Residential District, RSF. The property to the west of these development is zoned Planned Unit Development - Residential, PUD-R, Pheasant Hills. REZONING The existing zoning of the property, Rural Residential, is not consistent with the land use designation of the property, Residential Low Density. The Comprehensive Plan allows less intensive land uses to remain in place. However, any approval by the City for development of the property must be consistent with the Comprehensive Plan. The following zoning districts are consistent with a Residential Low Density land use: Low-density residential areas can be either zoned RSF (Residential Single Family), R-4 (Mixed Low Density), RLM (Residential Low and Medium Density), or PUD-R (Planned Unit Development Residential). The proposed rezoning to Single-Family Residential District (RSF) is consistent with the Comprehensive Plan land use designation. The RSF district is the most appropriate zoning district to rezone this property since it is the same zoning as the surrounding residential properties and permits only single-family homes. While the R-4 district permits single-family homes, it also permits twin homes which would be inconsistent with the surrounding development. The RLM district permits single-family homes, as well as twin homes, townhouses and attached housing. But the RLM district also requires that large areas of upland are preserved or created as permanent open space to balance the higher hard surface coverage permitted on the individual lots. Finally, the PUD-R district can be created for a single-family subdivision, but the ordinance requires that the minimum development size be five acres. Planning Commission Deer Haven December 1, 2020 Page 4 The proposed rezoning assists in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: • Development will be encouraged within the MUSA line. • The plan should seek to establish sufficient land to provide a full range of housing opportunities. • Development should be phased in accordance with the ability of the city to provide services. The proposed rezoning assists in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life-cycle. Staff is recommending the rezoning to RSF be approved. SUBDIVISION REVIEW The applicant is requesting subdivision review to create a four lot single-family residential development. Access will be a public street within existing city right-of-way out to Yosemite and a private street from this street in to the development. Planning Commission Deer Haven December 1, 2020 Page 5 PRELIMINARY PLAT RIGHT-OF-WAY, STREETS AND EASEMENTS In April 1985, 16.5 feet of right-of-way was dedicated for Tacoma Trail (easterly end of Wood Duck Lane) with the Stoddart Addition. In April 1987, 16.5 feet of right-of-way was dedicated for Wood Duck Lane with the Pheasant Hills 4th Addition. A total of 31 feet of right-of-way was dedicated for the road connection to Yosemite. As part of Pheasant Hills 4th Addition, 50 feet of right-of-way for Wood Duck Lane was dedicated to the north of the project site. The property being proposed to be subdivided (6480 Yosemite Avenue) is currently served by an approximate 10-foot wide private driveway had from Yosemite Avenue which extends through unimproved right-of-way (Tacoma Trail). The applicant is proposing to remove the driveway and extend a public street from Yosemite Avenue within the unimproved Tacoma Trail right-of-way and construct a private street to serve all four lots within the proposed subdivision, see image below. A small rectangle of public roadway easement is required to be obtained from the property owner due north of this subdivision in order to construct the public street (see image below). Obtaining this Planning Commission Deer Haven December 1, 2020 Page 6 easement is a requirement of the applicant, and a draft easement document has been created and reviewed by the city attorney. The property owner to the north has been engaged and had their own attorney review the easement. Official recording of this easement is a subject condition of the preliminary plat. Staff finds that the use of a private street is in general accordance with City’s Code of Ordinances (Ordinances), Sec. 18-57. While public right-of-way is abutting and adjacent to the property being developed, the prevailing development pattern makes it unfeasible to construct a standard width public street in accordance with current Ordinances due to the inadequate existing width of the unimproved right-of-way (33 feet wide). Conversely, if the applicant was to extend the public street from the end of Wood Duck Lane, which does have adequate right-of-way width, it would further exacerbate a non-conforming cul-de-sac length which is already approximately 1100 feet in length. As such, the applicant is requesting a variance from the standard right-of-way and street width outlined in Sec. 18-57. The variance request is to build a 24-foot wide public street within the existing 33-foot wide right-of-way. Additionally, as there are no other properties that take direct access to the proposed street, coupled with the street width variance, it is proposed to adopt a resolution prohibiting parking along this portion of the proposed public street. Engineering and Public Works staff have evaluated the alternatives and finds that the proposed variance to extend a public street within the unimproved portion of Tacoma Trail right-of-way is the most practicable and adequate alternative due to the existing constraints. The applicant will be required to supply with the final plat submittal cross-section details for the public street, account for public drainage, and the design of an adequate turn-around at the end of the public street. Lastly, updated construction plans shall indicate the locations of proposed street lights in accordance with Sec. 18-78.(b)(7) for review and approval by the City Engineer. Planning Commission Deer Haven December 1, 2020 Page 7 As the proposed development will have common sections of the private street that will serve two units or more with a density of less than four units per acre, the private street shall: be built to a seven-ton design, paved to be a width of 20 feet, utilize a maximum grade of ten percent, and provide a turnaround area acceptable to the fire marshal based upon guidelines provided by applicable fire codes and ordinances. It is recommended that a Homeowners Association be formed and the declarations address the maintenance responsibilities and associated costs of repairs for the private street. The applicant shall submit a street name for the private street for city review and approval. Private streets serving up to four lots may be permitted in residential developments with a density of less than four units per acre if the criteria in variance Section 18-22 are met and upon consideration of the following: (1) The prevailing development pattern makes it unfeasible or inappropriate to constrict a public street. In making this determination, the City may consider the location of existing property lines and homes, local or geographic conditions and the existence of wetlands. Planning Commission Deer Haven December 1, 2020 Page 8 (2) After reviewing the surrounding area, it is concluded that an extension of the public street system is not required to serve other parcels in the area, improve access, or to provide a street system consistent with the Comprehensive Plan. (3) The use of a private street will permit enhanced protection of the City's natural resources including wetlands and forested areas. The use of the private street meets the criteria specified in City Code since it is not necessary to provide access to adjacent properties, would create an excessive amount of hardcover with minimal public benefit and would require even more environmental impacts. DRAINAGE AND UTILITY EASEMENTS The preliminary plat provided illustrates mostly typical public drainage and utility easements (D&U) along the proposed subdivision’s lot lines with five-foot D&U along the side lot lines and 10-foot D&U along the front and rear lot lines. There is a portion of D&U abutting the front lot lines of Lots 1 and 2 along with the northeast corner of Lot 3 that extends eight additional feet (a total of 18 feet wide) in order to provide proper widths to maintain the sanitary sewer. The applicant has proposed the creation of Outlot A to cover the private street along with portions of undevelopable land abutting the street to the east. Outlot A is being proposed to be encumbered in its entirety with a D&U. While public water main and sanitary sewer main will be located within the Outlot, it is not necessary to encumber the entire Outlot in D&U as private improvements such as stormwater features will be located on Outlot A. The applicant shall update the final plat to include D&U within Outlot A only over the public utilities as required for adequate maintenance, repair and replacement. The widths shall be ten feet from the center of each utilities pipe on both sides. The location of the water main and sanitary sewer main is discussed later on in section “Sanitary Sewer and Water Mains”. GRADING AND DRAINAGE The portion of the site which accommodates the three new homes generally slopes gradually to the north, while the portion of the site with the existing home proposed to remain has steep slopes with gradient to the south. Grading for the development is being proposed over two phases; the first phase will grade areas associated with the public and private streets, the public utilities, the stormwater basins and the area where sanitary sewer will be extended from the west through unimproved right- of-way; the second phase was shown on the preliminary plans to illustrate feasibility and provides custom graded walkout lots. It appears drainage will be routed away from building pads and through backyards of the future lots via a swale which then directs overland flow towards a proposed stormwater basin on the most northern lot (Lot 1), while the front yards and road will sheet drain to the stormwater basin on the east side of the private street (northeast corner of Outlot A). However, drainage arrows were not provided on the preliminary plans and will be required upon submittal of final plat and final construction plans. Additionally, all requirements of grading plans as outlined under Sec. 18-40.(4)d. will be required upon submittal of final plat and final construction plans, including the appropriate scale, lowest floor elevations of buildings (proposed and existing), emergency overflow routes, stockpile locations, etc. Planning Commission Deer Haven December 1, 2020 Page 9 Lastly, no geotechnical report was provided to indicate that the in-situ soils are suitable for building foundations, public and private street designs, stormwater infiltration, or utility support and will need to be provided along with the final plat submittal. All recommendations from the geotechnical report shall be adhered to, and a geotechnical engineering firm shall be on site during grading operations as required to ensure the City’s Standard Specifications and Detail Plates are adhered to along with any Minnesota Building Code requirements. If groundwater is encountered during grading the grades shall be adjusted to maintain a 3 foot separation from the bottom floor elevation and adhering to the recommendations of the soil engineer on site. Changes to grades shall be submitted to the City for review and approval. RETAINING WALLS The applicant is proposing three retaining walls within the subdivision to accommodate potential walkout designs for the custom graded lots, as discussed above in “Grading and Drainage”. The height of any retaining wall is measured from the top of the wall to the bottom of the footing (not to the top of grade). The plans did not indicate the height of the walls and shall be updated accordingly upon submittal of final plat and final construction plans, however it does appear that at least one will have a height greater than four (4) feet. Walls over 4 feet in height shall be constructed in accordance with plans prepared by a registered engineer and shall be constructed of a durable material (smooth face concrete, masonry/mortared, railroad ties and timber are prohibited). EROSION PREVENTION AND SEDIMENT CONTROL As proposed it appears the development will not exceed one (1) acre of land disturbance and will, therefore, not be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). However, an Erosion and Sediment Control Plan (ESCP) in accordance with Ordinances shall be submitted for the grading operations of the subdivision as more than 5,000 square feet of land is being disturbed. The applicant has provided an ESCP along with a Stormwater Pollution Prevention Plan (SWPPP), and while overall the plan appears feasible, it is deficient as it does not include all the requirements listed under Sec. 19-145.(a)(2) such as the requirement that drainage boundaries and direction of drainage pre- and post-development be indicated. As such, the applicant shall update the ESCP and resubmit for review and approval with the submission of the final construction plans. As disturbance limits were near one acre, if this increases or is determined to be one acre or more, the applicant will be required to obtain the NPDES Construction Permit. SANITARY SEWER AND WATER MAINS The proposed subdivision has access to a 12” PVC public water main that is located within abutting unimproved right-of-way north of the property (Wood Duck Lane), however no public sanitary sewer main abuts the development. As such, the developer will be required to extend the sanitary sewer main located 150 feet west (Wood Duck Lane cul-de-sac) of the development’s northwest Planning Commission Deer Haven December 1, 2020 Page 10 property corner in order to serve the site. Based on the preliminary plans, the applicant is proposing to extend both of these public utilities into the subdivision to serve the newly created lots, as seen below. The proposed alignments of the extended public utilities are in general conformance with City Standards and Specifications. However, the applicant is proposing an 8” PVC water main, while the City Standard Specifications allow for a minimum 6” main where feasible. If a 6” main will supply adequate fire flows and pressures to the newly formed subdivision, the main shall be downsized accordingly. All newly installed public utilities will be required to adhere to the City of Chanhassen’s Standard Specifications and Detail Plates, which will be the governing specifications for said improvements. Upon acceptance by City Council the sanitary sewer and water mains will become publicly owned and maintained. The existing home’s water service lateral is proposed to be abandoned and tied into the newly proposed water main, which is beneficial to the water quality for the subdivision as the newly created extension dead-ends, however the existing home’s sanitary sewer service is proposed to remain. As the preliminary plans indicate that the existing home’s sanitary sewer service, which extends to the west between 1671 and 1681 Pintail Circle, may be located outside the prescribed easements, the applicant will be required to either expand the easement area to encompass the lateral in its entirety, or, verify that the existing alignment is in fact within the easement, or, connect the existing home to the newly extend sanitary sewer. Updated plans shall be provided illustrating the approach taken. Planning Commission Deer Haven December 1, 2020 Page 11 While generally the preliminary utility plans provided do appear feasible, profile views were not provided in order to conduct a complete review, e.g. checking for conflicts with other utilities or reviewing cover of mains to meet City standards. The applicant will be required to provide updated utility plans upon submittal of the final plat and final construction plans that include profile views. Lastly, prior to commencement of any utility work, a copy of all required permits from the appropriate regulatory agencies shall be provided to the City which shall include but is not limited to the Minnesota Department of Health, Metropolitan Council Environmental Services, and the Minnesota Pollution Control Agency. STORMWATER MANAGEMENT Article VII, Chapter 19 of City Code describes the required stormwater management development standards. Section 19-141 states that “these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features.” These standards include abstraction of 1.0 inch of runoff from the new impervious surfaces created by the project and water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). The applicant will need to work with Minnehaha Creek Watershed District (MCWD) and the City in order to meet all the requirements. General 1. MCWD has notified the City that the development triggers MCWD Stormwater Management rules because the parcel is being split into 3 or more lots and increasing impervious surface. Applicant will be required to obtain a permit through MCWD. Water Quality 1. Page 1 of the hydrology report states “Soils information is assumed to be mostly D soils, based on the area and the wetland to the north. Filtration will be used to reduce runoff rates, and volumes.” Soil borings should be provided to confirm the web soil survey data is correct and to confirm infiltration is not feasible. If soil borings show infiltration is feasible, infiltration should be used to meet stormwater management requirements. This would also allow for smaller basins. a. If infiltration cannot be used, an abstraction analysis must be provided according to MCWD Stormwater Management Rule 3(c)(2)(i). 2. Applicant should include information on how pretreatment will be provided for the proposed biofiltration basins in the hydrology report (i.e. vegetated filter strips). Rate Control 1. Outlet pipe slopes in HydroCAD should be updated to be consistent with what is shown in the plans. 2. If a biofiltration basin continues to be proposed, applicant should route exfiltration downstream instead of it being discarded in HydroCAD. Planning Commission Deer Haven December 1, 2020 Page 12 Volume Control 1. Based on the impervious areas included in the hydrology report and according to MCWD Stormwater Rule 5(c), (and shown in Table 4 in Section 11) the site: a. is greater than 1 acre b. is disturbing less than 40% of the site c. is increasing the existing impervious surface by more than 50% Therefore, the MCWD rules state that the entire site’s impervious surface (18,142 sf) must be accounted for in calculations for water quality, rate control, and volume control. Currently the applicant is providing calculations for only the additional impervious surface. Applicant should confirm proposed impervious area as noted previously and confirm which MCWD requirements apply based on Table 4 in Section 11 of MCWD Rule N. 2. Water quality volume credit is given at a 0.5 rate for filtration basins according to MCWD Volume Abstraction Credit Schedule (Appendix A of MCWD Rule N). With the 0.5 factor applied the proposed basins do not provide the required water quality volume. Applicant should update the subsequent water quality volume calculations with the 0.5 credit rate applied and provide updated HydroCAD stage/storage data (shown at the outlet elevation to confirm water quality volume) for both ponds. Filtration Basin Design 1. If a biofiltration basin continues to be used, applicant should update the MIDS calculations to reflect a filtration basin with underdrain to get accurate modeling results. 2. Provide an operation and maintenance plan that identifies the maintenance schedule and responsible party. This should include information on how the system will be cleaned out. Flood Elevation 1. The City of Chanhassen requires low floor elevations to maintain at least three feet of freeboard to adjacent ponding areas HWL and floodplains. Per the submitted report, the NW filtration basin (2P) has a 100-year HWL of 1026.49’. Applicant should include the low opening and low floor elevations for the proposed buildings and make sure the elevation allows for three feet of freeboard above the basins. Civil Plans 1. Applicant is showing grading and utility work north of the parcel boundary. Applicant must show easements on plans for all improvements outside of property limits. 2. Easements must be shown for on-site storm sewer and around ponding areas if public. 3. Operations and Maintenance Plan to include maintenance schedule and entity responsible for maintenance must be provided for any private utility or pond. 4. Proposed draintile should be shown in the plans tying to the overflow structure. Applicant should include draintile size, slope, inverts and cleanout locations. 5. Update detail to reflect filtration bioretention basin instead of infiltration basin (depending on outcome of soil borings). 6. Provide details for silt fence and rock construction entrance. Planning Commission Deer Haven December 1, 2020 Page 13 7. FES must have energy dissipation with appropriately sized and quantity of rip rap. Show rip rap detail on the plans. 8. The proposed area included in SWPPP note #3 site data in the full plan set doesn’t match the proposed impervious area listed in the hydrology report. Applicant should confirm impervious areas and update plans/hydrology report as needed. 9. Emergency overflow elevations and location should be included on the plans for both basins. 10. Storm sewer must be 12” minimum per city requirements. 11. Add inlet protection to the eastern catch basin on Yosemite Avenue near the construction entrance. 12. Two lines of silt fence should be placed adjacent to the wetland. 13. The NW basin is shown within 15’ of the adjacent building. Applicant may want to consider adjusting the design to provide further separation between the pond and structure. Staff requests that the applicant address each of the comments above and provide a written response by restating each comment and stating how each comment was addressed and include supporting documentation. Please feel free to reach out with any questions. WETLANDS AND BUFFERS One wetland was identified and delineated on and near the property. The wetland is classified as Type 1, seasonally flooded basin. 0.03 acres of the wetland exist on the subject property, however initial plans show that none of this area is anticipated to be impacted by the project. If any wetland impacts are proposed going forward a wetland replacement plan would need to be approved through the Wetland Conservation Act permitting process. On additional area was investigated as part of the wetland delineation. The area, in the southeast corner of the lot, was determined to be upland. The on-site TEP review concurred with this determination. STORMWATER UTILITY CONNECTION CHARGES Section 4-30 of City Code sets out the fees associated with surface water management. A water quality and water quantity fee are collected with a subdivision. These fees are based on land use type and are intended to reflect the fact that the more intense the development type, the greater the degradation of surface water. This fee will be applied to the new lots of record being created. The fees will be assessed at the rate in effect at that time; 2020 rates are $8,490.00 per acre. ASSESSMENTS Water and sewer partial hookups are due at the time of final plat. The partial hookup fees will be assessed at the rate in effect at that time; 2020 rates for partial hookup fees are $691.00 per unit for sanitary sewer and $2,392.00 per unit for water. The remaining partial hookups fees are due with the building permit. Planning Commission Deer Haven December 1, 2020 Page 14 Fees Based on the proposal, the following fees would be collected with the development contract: a) Administration Fee: if the improvement costs are less than $500,000, 3% of the improvement costs. If the improvement costs are between $500,000 and $1,000,000, 2% of the improvement costs. If the improvement costs exceed $1,000,000, 2.5% of the first $1,000,000 plus 1.5% of the remainder. b) Surface Water Management Fee: $8,490.00 per acre. c) A portion of the water hook-up charge: $2,392.00/unit d) A portion of the sanitary sewer hook-up charge: $691.00/unit e) Park Dedication Fee: $17,400.00 f) GIS fees: $25 for the plat plus $10 per parcel g) Final plat process (review and recording of Plat and DC): $450.00 LANDSCAPING AND TREE PRESERVATION The applicant for the Deer Haven Addition has submitted tree canopy coverage and preservation calculations. They are as follows: Total upland area (excluding ROW) 3.45 ac. or 150,257 SF Baseline canopy coverage 39% or 59,059 SF Minimum canopy coverage required 30% or 45,077 SF Proposed tree preservation 30% or 45,786 SF The developer appears to meet minimum canopy coverage for the site, but will need to verify calculations before final approval. The tree preservation plan shows trees to be preserved within the grading limits which is not feasible as shown. This is especially true of the grouping of trees located at the rear of lot 3. None of the trees are in good health and will have significant grade changes throughout their root zones. The applicant will need to revise the grading limits to preserve trees or update the tree preservation plan to reflect tree removal within the grading limits. A minimum of one tree is required to be planted in the front yard of each new home as required by ordinance. No buffer yards are required as all neighboring properties have the same land use. The applicant has proposed trees to be planted in Outlot A. PARKS AND RECREATION The quality and number of recreational facilities in a community directly contributes to its quality of life. For this reason, the City of Chanhassen places a strong emphasis on parks and open space. As the City of Chanhassen has developed and increased in population, more pressure and attention has been given to providing recreational opportunities for our residents. Increased leisure time, health awareness, greater mobility, and high disposable incomes have all contributed to the increased demand for recreational activities. The challenge of the next century will be to provide facilities for a growing and diverse population. Planning Commission Deer Haven December 1, 2020 Page 15 Parks can be defined as public areas that provide active or passive-oriented recreational facilities. A significant characteristic of parkland is its accessibility to its users. Open space is any parcel that is not used for buildings or other structures and is left in a natural state. Parks and open space perform diverse functions such as: meeting physical and psychological needs, enhancing and protecting the resource base, enhancing real estate values, and providing a positive impact on economic development. Parks The goal of neighborhood parks is to provide informal recreational opportunities close to where people live. The City’s Comprehensive Park Plan calls for a neighborhood park to be located within one-half mile of every residence in the city. The Deer Haven Addition is located within one-half mile of both Curry Farms Park and Pheasant Hill Park. These two neighborhood park locations offer ample amenities for those residing in the Deer Haven Addition. Trails The City’s goal is to maintain a comprehensive and easily navigable trail and sidewalk system that connects neighborhoods to park and recreation facilities, schools, community destinations and other communities. No trail or sidewalk facilities are located in the vicinity of this development. Park and Trail Conditions of Approval Full park fees in lieu of parkland dedication and/or trail construction are to be collected. The park fees shall be collected in full at the rate in force upon final plat submission and approval. At today’s rate, these fees would total $5,800 (3 lots x $5,800 per lot) for three new lots without charging the existing home. MISCELLANEOUS The road width proposed of 24 feet would require No Parking Fire Lane signs on both sides. Planning Commission Deer Haven December 1, 2020 Page 16 Building plans must provide sufficient information to verify that the proposed building meets all requirements of the Minnesota State Building Code, additional comments or requirements may be required after plan review. A building permit must be obtained before beginning any construction. Retaining walls more than four feet high must be designed by a professional engineer and a building permit must be obtained prior to construction. If any soil corrections are done on the property, a final grading plan and soil report must be submitted to the Inspections Division before permits will be issued. COMPLIANCE TABLE Area (sq. ft.) Width (ft.) Depth (ft.) Hard Cover % / sq. ft. Notes Code 15,000 100* 125 25 / 3,750 *Property access via a private street 1 15,148 112 152 25/3,787 Front lot line east, corner lot 2 15,079 100 151 25/3,769 Front lot line east 3 18,012 102 140 25/4,503 Front lot line east 4 47,843 241 178 25/11,960 Front lot line east A 26,297 Private street, 0.6 acres Total 122,379 2.81 acres Setbacks (ft.): 30 - front, 10 - side, 30 - rear Planning Commission Deer Haven December 1, 2020 Page 17 VARIANCE The hardship is not a mere inconvenience by providing reasonable access to four properties while reducing potential impacts to the natural features on the site and within existing off-site right-of- way; The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land including trees; a public street is not necessary to provide access to adjacent properties within the development and the existing right-of-way and surrounding development preclude additional public right-of-way out to Yosemite; The condition or conditions upon which the request is based are unique and not generally applicable to other property because of the previously stated conditions of the property; The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of subdivision regulations, the zoning ordinance and Comprehensive Plan since it will reduce potentially significant impacts on the site and within the neighborhood. RECOMMENDATION Staff recommends that the Planning Commission approve the rezoning from Rural Residential District (RR) to Single-Family Residential (RSF), and Subdivision approval with a Variance to create four lots and one outlot subject to the following conditions and adoption of the Findings of Fact and Recommendation: REZONING: 1. Contingent on final plat approval. SUBDIVISION WITH VARIANCES: Building: 1.

ATTACHMENTS Findings of Fact and Recommendation Development Review Application Preliminary Plat Full Plan Set Public Hearing Notice and Mailing List g:\plan\2020 planning cases\20-22 6480 yosemite avenue (deer haven) sub\staff report deer haven.docx 1 CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION IN RE: Application of Kenneth Ashfeld and Barbara Bersie-Ashfeld – Planning Case No. 2020-22, Deer Haven Addition. Request for Rezoning from Rural Residential District, RR, to Single-Family Residential District, RSF, Subdivision Approval creating four lots and one outlot with a Variance for a public street cross section and right-of-way width, and a Variance for the use of a private street located at 6480 Yosemite. On December 1, 2020, the Chanhassen Planning Commission met at its regularly scheduled meeting to consider the application of Kenneth Ashfeld and Barbara Bersie-Ashfeld for a single-family residential development. The Planning Commission conducted a public hearing on the proposed development preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned Rural Residential District, RR. 2. The property is guided in the Land Use Plan for Residential – Low Density uses. 3. The legal description of the property is: That part of the Southeast Quarter of the Northeast Quarter of Section 3, Township 116, Range 23, Carver County, Minnesota, described as follows: Beginning at the Northeast corner of said Southeast Quarter of the Northeast Quarter; thence Southerly along the East line of said Southeast Quarter of the Northeast Quarter to a point 660 feet North of the Southeast corner of said Southeast Quarter of the Northeast Quarter; thence Westerly parallel with the South line Southeast Quarter of the Northeast Quarter a distance of 281.07 feet; thence Northeasterly to a point on the North line of said Southeast Quarter of the Northeast Quarter distance 198.0 feet Westerly from the point of beginning; thence Easterly along said North line 198.0 feet to the point of beginning, except the North 50.0 feet thereof, Carver County, Minnesota. Records of Carver County, Minnesota. 4. REZONING FINDINGS The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse affects of the proposed amendment. The six (6) affects and our findings regarding them are: 2 a. The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official City Comprehensive Plan. b. The proposed use is or will be compatible with the present and future land uses of the area. c. The proposed use conforms with all performance standards contained in the Zoning Ordinance. d. The proposed use will not tend to or actually depreciate the area in which it is proposed. e. The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. f. Traffic generation by the proposed use is within capabilities of streets serving the property. 5. SUBDIVISION FINDINGS a. The proposed subdivision is consistent with the zoning ordinance and meets all of the requirements of the “RSF” Single-Family Residential District; b. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the City's Comprehensive Plan; c. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and stormwater drainage are suitable for the proposed development; d. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by the subdivision ordinance; e. The proposed subdivision will not cause significant environmental damage subject to compliance with conditions of approval; f. The proposed subdivision will not conflict with easements of record, but rather will expand and provide all necessary easements; g. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: 1) Lack of adequate stormwater drainage. 2) Lack of adequate roads. 3) Lack of adequate sanitary sewer systems. 4) Lack of adequate off-site public improvements or support systems. 3 6. VARIANCE FINDINGS WITH A SUBDIVISION a. The hardship is not a mere inconvenience by providing reasonable access to four properties while reducing potential impacts to the natural features on the site and within existing off- site right-of-way; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land including trees; a public street is not necessary to provide access to adjacent properties within the development and the existing right-of-way and surrounding development preclude additional public right-of-way out to Yosemite; c. The condition or conditions upon which the request is based are unique and not generally applicable to other property because of the previously stated conditions of the property; d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of subdivision regulations, the zoning ordinance and Comprehensive Plan since it will reduce potentially significant impacts on the site and within the neighborhood. 7. The planning report #2020-22 dated December 1, 2020, prepared by Robert Generous, et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that the City Council approve the proposed Preliminary Plat approval for four lots and one outlot, variances for public street cross-section and right-of-way with a Variance for the use of a private street for a single-family detached subdivision subject to the conditions of the staff report. ADOPTED by the Chanhassen Planning Commission this 1st day of December, 2020.

A rezoning must be consistent with the city’s Comprehensive Plan. Notice of this public hearing has been mailed to all property owners within 500 feet. PROPOSED MOTION: “The Chanhassen Planning Commission recommends approval of rezoning the property located at 1601 Lake Lucy Road, with an approximate area of 9.03 acres, from Rural Residential to Planned Unit Development-Residential incorporating the attached standards and adoption of the Finding of Fact and Decision Recommendation.” Subject Property Lake Lucy Road Lake Lucy Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 2 of 10 APPLICABLE REGULATIONS Chapter 20, ARTICLE VIII. - PLANNED UNIT DEVELOPMENT DISTRICT BACKGROUND LOCATION/SITE DATA The site is located south of Lake Lucy Road and is surrounded by Lake Lucy. The site has an area of approximately 9.03 acres and is currently zoned Rural Residential District, RR. Access to the site is gained via Lake Lucy Road. ACCESS AND BRIDGE On December 13, 1993, the City Council approved a request for a Wetland Alteration Permit to allow improvements to a driveway and installation of a bridge to access the subject site. Three extensions were approved to this permit with the final extension granted on January 27, 1997. The work on the installation of the bridge and the driveway was completed on February 25, 1999. Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 3 of 10 LAND USE PLAN The Land Use Plan designates the areas around Lake Lucy as Residential. The subject site is designated Low Density Residential. This designation has been established to accommodate most residential districts are comprised of low-density, single-family detached housing. Within this category, net densities range from 1.2 to 4 units per acre. Low-density residential areas can be either zoned RSF (Residential Single Family), R-4 (Mixed Low Density), RLM (Residential Low and Medium Density), or PUD-R (Planned Unit Development-Residential). The owner of the subject property is requesting to build two homes, one of which is an Accessory Dwelling Unit. The density is in keeping with the guidelines of the Comprehensive Plan. Subject Site Low Density Residential (Net Density 1.2-4 U it /A Residential Large Lot (2.5 Acres minimum. 1/10 Units per Acre) Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 4 of 10 REZONING The applicant is requesting to rezone the property from Rural Residential, RR to Planned Unit Development-Residential, PUD-R. The 2040 Land Use Plan shows this area designated for development as Low Density Residential. Appropriate zoning for this land use includes RSF, (Single-Family Residential), R-4 (Mixed Low Density), RLM (Residential Low and Medium Density), or PUD-R (Planned Unit Development- Residential). Staff has been working with the applicant since 2018. The site is unique and is the only island in the city. The typical “one size fits all” ordinances do not work well in this case. They can trigger requirements that would cause significant degradation to the site. The site contains bluffs, is within the Shoreland Overlay District of Lake Lucy and has a 100% tree canopy cover. Subject Site Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 5 of 10 This is a lot of record and is entitled to build a single family home. The applicant’s request was to have a principle structure with an Accessory Dwelling Unit. This can either be achieved via subdivision or rezoning the site to Planned Unit Development (PUD). Subdivision Impacts: • Widening the existing driveway to 20 feet which will result in wetland fill. • Additional grading. • Additional tree removal. • Additional hard surface. • Adding the potential for two additional homes with a minimum lot area of 20,000 square feet (up to 4 lots can be served via a private street which would require a variance). • Additional grading with the potential extension of utilities. PUD Impacts • Use of the existing private driveway. • One septic and well site. • Cap on the size of the Accessory Dwelling Unit. • Requiring the use of a single eternal driveway. • The PUD is the governing document that will establish limitations on the site. As options were evaluated, the applicant chose to request a PUD rezoning. Staff advised that the zone must have a minimum area of five acres which the subject site exceeds. Also, the Planned Unit Development ordinance permits two structures on a single lot. The use of a PUD allows the city to create a set of regulations that are unique to this property and ensures a higher set of standards is developed to govern this site. Staff directed the applicant to develop a concept plan. All comments are based on a concept that has the potential to change. The regulations that will be incorporated into the ordinance governing the site, will aim to improve the environmental quality of the site. Referrals were sent to agencies and city staff to gather feedback on how to improve development of this site. The one common theme was to combine the driveways accessing the structures. Staff discussed this recommendation with the property owner and he agreed to the recommendation. The applicant has demonstrated a continuous good faith effort in addressing concerns by making revisions to conceptual designs, improving the quality of vegetation on the island by removing buckthorn which is an invasive species. Development of the site will be governed by ordinances that will promote better development standards. The applicant is requesting the maximum floor area of the Accessory Dwelling Unit not to exceed 1,600 square feet. As a general rule, the city does not allow two dwelling units on a single lot. The use of the PUD would allow for the two structures. This application of a PUD cannot be applied to other large lots in the city because they are guided Large Lot (2.5 Acre Minimum-1/10 Units per Acre. Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 6 of 10 NEIGHBORHOOD MEETING The applicant’s intent was to hold a neighborhood meeting to address questions and comments from neighboring properties. Due to the social distancing circumstances, this was not an option. The applicant did communicate via e-mail with property owners around Lake Lucy. Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 7 of 10 LANDSCAPING The applicant for the development of 1601 Lake Lucy has submitted tree canopy coverage and preservation calculations. They are as follows: Total upland area 7.07 ac. or 308,303 SF Baseline canopy coverage 100% or 308,303 SF Minimum canopy coverage required 55% or 169,566 SF Proposed tree preservation 61% or 188,577 SF The calculations are included to illustrate that the rezoning to PUD-R would meet the subdivision standards for tree removal. Since the plan submitted is conceptual, there is the possibility that the proposed tree preservation could increase or decrease. Planned unit developments are generally considered when the applicant can offer enhanced environmental preservation or increased sensitivity to the site. It is unclear as to whether or not the final building submittal will provide that, but staff recommends that the applicant explore opportunities for increased tree preservation on the property. ENGINEERING GENERAL COMMENTS Any and all utility and transportation plans submitted with this application have been reviewed only for the purpose of determining the feasibility of providing public utility and transportation facilities for the proposed PUD in accordance with the City of Chanhassen Standard Specifications and Detail Plates (City Standards) and the Chanhassen Code of Ordinances (Ordinances). A recommendation of approval does not constitute final approval of details, including but not limited to alignments, materials and points of access, grading, utility connections or points of discharge, which are depicted or suggested in the application. The applicant is required to submit detailed construction drawings and/or supplemental information for the project with the building permit and/or Development Stage Application, as applicable. The City of Chanhassen Engineering and Public Works Department will review plans, in detail, when they are submitted and approve, reject or require modifications to the plans or drawings based upon conformance with City Standards, the Ordinances, the PUD plan, and the professional engineering judgment of the City Engineer. As such, it is the opinion of the Engineering Department that the proposed PUD can be developed in accordance with the requirements of the Ordinances (as it pertains to Engineering and Public Works requirements) and City Standards. However, after review of the PUD rezoning submittal materials, being conceptual in nature without much information, Engineering and Public Works staff did not find that the concept plan provided a significantly higher quality or more sensitive proposal (Sec. 20-501), or offered enhanced environmental sensitivity beyond normal ordinance requirements (Sec. 20-506) as it pertains to Engineering and Public Works requirements. PUD FINDINGS The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse effects of the proposed amendment. The six (6) affects and our findings regarding them are: Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 8 of 10 a) The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official city Comprehensive Plan. Finding: The proposed Planned Unit Development has been considered in relation to the specific policies and provisions of the land use plan and has been found to be consistent with the official city Comprehensive Plan. It complies with providing single-family homes that meet density requirements. b) The proposed use is or will be compatible with the present and future land uses of the area. Finding: The proposed use is compatible with the present and future land uses of the area. Staff has prepared an ordinance that will regulate the site and ensure specific regulations are adhered to. c) The proposed use conforms with all performance standards contained in the Zoning Ordinance. Finding: The proposed uses will conform with all performance standards contained in the Zoning Ordinance such as bluff setbacks, shoreland setbacks, etc. The ordinance regulating the site will add additional higher standards and establish limitations that govern the site. d) The proposed use will not tend to or actually depreciate the area in which it is proposed. Finding: The proposed use is consistent with and compatible with all surrounding parcels that have been guided or have developed as single-family homes. e) The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. Finding: The site is located within the Municipal Urban Service Area however, due to the location of the island in relation to utilities and due to the potential impact on the natural features of the site, the applicant will provide an on-site septic system and well. The applicant also intends to sprinkle the home. These steps will ensure the proposed use will not overburden the city's service capacity. f) Traffic generation by the proposed use is within capabilities of streets serving the property. Finding: The request is for a single-family home and an accessory dwelling unit. Traffic generation by the proposed use is within capabilities of streets serving the property. Planning Commission 1601 Lake Lucy Road Rezoning December 1, 2020 Page 9 of 10 RECOMMENDATION Staff recommends adoption of the following motion: The Planning Commission recommends approval of rezoning the property located at 1601 Lake Lucy Road with an approximate area of 9.03 acres from Rural Residential to Planned Unit Development-Residential, incorporating the following standards: PUD DEVELOPMENT DESIGN STANDARDS a.

The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned Rural Residential District, RR. 2. The property is guided in the Land Use Plan for Residential Low Density. 3. The legal description of the property is shown in the attached Exhibit A. 4. The Zoning Ordinance directs the Planning Commission to consider six (6) possible adverse affects of the proposed amendment. The six (6) affects and our findings regarding them are: a) The proposed action has been considered in relation to the specific policies and provisions of and has been found to be consistent with the official city Comprehensive Plan. Finding: The proposed Planned Unit Development has been considered in relation to the specific policies and provisions of the land use plan and has been found to be consistent with the official city Comprehensive Plan. It complies with providing single-family homes that meet density requirements. b) The proposed use is or will be compatible with the present and future land uses of the area. Finding: The proposed use is compatible with the present and future land uses of the area. Staff has prepared an ordinance that will regulate the site and ensure specific regulations are adhered to. 2 c) The proposed use conforms with all performance standards contained in the Zoning Ordinance. Finding: The proposed uses will conform with all performance standards contained in the Zoning Ordinance such as bluff setbacks, shoreland setbacks, etc. The ordinance regulating the site will add additional higher standards and establish limitations that govern the site. d) The proposed use will not tend to or actually depreciate the area in which it is proposed. Finding: The proposed use is consistent with and compatible with all surrounding parcels that have been guided or have developed as single-family homes. e) The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. Finding: The site is located within the Municipal Urban Service Area however, due to the location of the island in relation to utilities and due to the potential impact on the natural features of the site, the applicant will provide an on-site septic system and well. The applicant also intends to sprinkle the home. These steps will ensure the proposed use will not overburden the city's service capacity. f) Traffic generation by the proposed use is within capabilities of streets serving the property. Finding: The request is for a single-family home and an accessory dwelling unit. Traffic generation by the proposed use is within capabilities of streets serving the property. 5. The planning report #2020-18 dated December 1, 2020, prepared by Sharmeen Al-Jaff, et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that the City Council approve the Planned Unit Development. ADOPTED by the Chanhassen Planning Commission this 1st day of December, 2020.

PUD Rezoning Request I am asking the City of Chanhassen to consider rezoning our property located at 1601 Lake Lucy Road, to Planned Unit Development - Residential. The property itself is unique, primarily because it is an island. A road and bridge were constructed out to the island approximately 22 years ago. For several years my wife and I have been looking for a larger parcel of land to build a home. A primary reason for that was so we could build a living space nearby for my mother who is now 86 years old. The island was a perfect opportunity for us to build living quarters near but still allow my mother to keep her independence. In the fall of 2018, we set out to design a home that would achieve all of these goals by creating essentially two living structures combined by a tunnel or skyway. Unfortunately, every option we explored led to a dead end. The island is an amazing piece of geography - beautiful in every way, but it also provides many home building challenges to overcome. After trying to “piece together the puzzle” for a year, we paused our design plans as we were temporarily exhausted from running into blockers. After consulting with our architect, we realized that the opportunity to create two separate living structures on the 8 acre parcel (not including the driveway down to the island) dramatically simplifies many aspects of the design and build. To accomplish this goal, we needed some flexibility of ordinances. This is the reason we are requesting a rezoning of the island to Planned Unit Development - Residential. This zoning category allows flexibility, but in turn requires high design standards. I hope to demonstrate that we intend to meet the higher standards. We have included several documents to add some additional context to the application and address some known concerns in your consideration. Included are: A composite map showing all of the highlighted features together. A map showing a preliminary design of the two living structures and accessory building and the total buildable area. A map showing proposed (but optional) water preservation areas. A map showing no water preservation areas. A map showing the total grading limits without the water preservation areas. A map showing the total grading limits with the water preservation areas. A map showing the total hard surfaces for the plan and the septic system and drainfield area. A Site Information summary showing critical square footage elements and calculations of these designs. A septic system drainfield sizing analysis by a licensed septic designer. The natural beauty of the island is undeniable, but in 2018 it was deep into the cycle of being overtaken by an invasive species - buckthorn. Shortly after purchasing the property, we worked with Jill Sinclair to get direction on removing the buckthorn. This was no simple matter. This invasive species was quite literally taking over the island and muscling out other native trees and plants. We hired one of the specialists Jill recommended and cut, treated and removed an astonishing amount of buckthorn. That effort returned the island to it’s natural balance. In our plans to build we intend to preserve that beauty in every way possible. We are planning to build “green” structures using solar for power, geothermal for heating/cooling, green roofs on parts of the structures, highly efficient building designs, rain water harvesting for watering the lawn and vegetation and various other plans to minimize our impact on the environment. Furthermore, as we get deeper into the design process, we plan to engage a civil engineer to assist with both a grading and erosion control plan to introduce the appropriate amount of water management located near the driveways to account for any run-off towards the lake including french drains, rain garden, etc. Given the majority of the current bluff conditions (mainly exposed soli), we propose addressing any susceptible bluff areas with native plantings to help mitigate potential erosion. Obviously, in the building process we will be impacting the island and vegetation, but the bulk of the tree removal will be on the interior of the island and the driveways on the island are designed to be appropriately narrow for the tree canopy to grow over. The bluff areas and shorelines will not be affected in terms of tree and canopy coverage. The grading limits and calculations have been provided in the accompanying documents. Additionally, we have ordered a tree survey from an expert (again recommended by Jill - thank you Jill!) and will make it available as soon as it is complete. A few weeks ago, I was able to walk the island with the Fire Chief, Don Johnson. Don shared his concerns and recommendations. One concern he shared was the ability for the larger fire trucks to navigate the island and have the ability to turn around. Since then, we have updated our plans to allow for turn around areas for the fire trucks. Don also recommended we design the living structures with fire suppression sprinkler systems. We plan to incorporate this into our designs going forward. Lastly, we hired a licensed septic designer (sourced from the approved contractor list on the Carver County website) to do some preliminary calculations to ensure we have enough area for the septic system and primary and secondary drain fields. The architectural drawings allow for 12,984 square feet for the septic system while his calculations call for only 11,000 square feet. Thank you for your consideration.

WEINGART 1685 STELLER COURT, EXCELSIOR, MN 55331 Mobile: (952) 239-5899 Email: alanweingart@gmail.com November 18, 2020 TO: Elise Ryan, Mayor Chanhassen City Council Chanhassen Planning Commission RE: Support of Wicka Rezoning of Island Property I am writing this letter of support having had over 25 years of experience with the island property that the Wicka’s are looking to rezone and build their home on. My spouse, Mary, and I purchased the island property back in 1994. At that time we also purchased the adjacent property at 1685 Steller Court, where we currently reside, from the same prior owners. We acquired certain permits with the property and began planning to construct vehicular access to the property. This process involved multiple governmental agencies, including the City of Chanhassen, the DNR and the Watershed District (Sharmeen al Jaff’s memory banks can be accessed for how this process unfolded and concluded!!). The 1800’ driveway and 72’ bridge were constructed over the 1998 – 1999 timeframe. Significant wetland mitigation, supervised closely by the City and the DNR, was completed during that construction timeframe. We left the island property in its natural state and used it for family and friend activities and as access to Lake Lucy for canoeing, kayaking and dog exercising. After our two sons grew up, we found ourselves using the property less and less, and reluctantly put it on the market in 2018. We were reluctant to sell it because we had thought about building on it but chose to build a Colorado home instead. Being adjacent to this property, we have a very unique setting from our home that overlooks the island property. Privacy has always been an important reason for living where we do, so selling the property was difficult for us, other than for the obvious remuneration we could receive. During the island sale process we were introduced to prospective buyers John & Anne Wicka. The sale process with them went smoothly and our reservations on selling the property quickly dissipated once we had met both of them. It quickly became evident that John and Anne had as much, if not more, respect for the integrity and environmental sensitivity of the island as we did. We discussed the topography, wetlands, wildlife, etc. with them and came away impressed with their desire to maintain as much ‘naturalness’ as they could when building their dream home on the property. One of the first things they did after buying was completely remove all of the buckthorn on the island and along the driveway. ALAN R. WEINGART 1685 STELLER COURT, EXCELSIOR, MN 55331 Mobile: (952) 239-5899 Email: alanweingart@gmail.com So, as not only the seller of the island to the Wicka’s, but also as an immediate neighbor, I fully support the City granting them a rezoning of the island property that allows for no more than two living structures, no subdividing or selling the property separately (the island always has to remain as one), amongst other reasonable restrictions that go along with such a rezoning. I believe that they are more than capable, financially and intentionally, of carrying out this rezoned building process in an environmentally-sensitive manner that blends in with the natural beauty of that unique parcel. Please let me know if any of you have questions on this zoning application as I am available to discuss and comment on any aspects of this property that may be of interest or concern to you.

This is a Zoom meeting and we are getting I think good at it. Please be patient with us as we work through different types of phone and other methods of communicating. Please, to the commission members please do not hold conversations, chats or instant messages outside of this meeting with each other. All of our discussions must be public and on the public record. Again we have one item on tonight’s agenda. Staff will present the item. Planning Commission will have a chance to ask questions or clarifications of staff. We don’t have an applicant right? Aanenson: No, we’re the applicant, yep. Weick: Right. And after staff’s presentation and questions we will have a public hearing.

At that time we will close the public once we’ve heard from everybody and everybody will be heard. We’ll close the public hearing and at that time the Planning Commission can comment and consider motions and a vote. This evening again we have one item. PUBLIC HEARING: CONSIDER A CODE AMENDMENT REGULATING THE OUTDOOR STORAGE OF BOATS, TRAILERS AND RECREATIONAL VEHICLES ON RESIDENTIAL PROPERTIES. Chanhassen Planning Commission – November 17, 2020 2 Aanenson: Thank you Chairman. I think it might be helpful too tonight that if after we make our presentation that we take the public comment before we go around the Planning Commission because the public hearing might be a lot of genesis of some of the questions so. Weick: So your presentation directly into, okay. Aanenson: Yeah unless that’s something that is a burning question that we missed on that but I think that might help in the summary there too so. As you mentioned Chair the Planning Commission just makes recommendations so this item does go to the City Council with a recommendation from the Planning Commission. So this, the genesis for this code amendment was based on the fact that there’s been some residents who have expressed a desire to store boats and trailers or recreational vehicles on their property. …history in our staff report goes back, the history goes back to the 70’s. 1972 and it said all storage had to be in the back yard and then that was modified to put it into a side yard. As we pointed out over time some of those lots in those PUD’s only have a 5 foot, 7 foot setback, side yard setback so it doesn’t always accommodate. And then in 1986 the storage of vehicles, again as I mentioned moved to the side yards. Again this ordinance has been in place for a number of years. I think people are kind of used to it and but there has been a lot of push to say you know, why can’t we put them in the driveway so what this amendment proposes to do is kind of look at all sides and come up with a potential solution. So the proposed solution is really look at one boat trailer or recreational vehicle be located within the driveway limits just storage the maximum of these two items in the outdoors. Adoption performance would mitigate any impact to the driveways so if you look through there’s 6 main criteria that were identified as concerns. And potentially those have changed you know. The storage area, and that storage area, one of the things we want to make that was identified is the storage area that it didn’t go over, because we wanted to make sure there’s sight lines if someone’s backing up that they can see around the neighbor’s driveway. You know whether it’s an RV or a large sailboat so that was one of the issues that was addressed. And then in addition to that the second was, has to do with the side yard setbacks, the 5 yard setback. We talked about that. It’s no, that’s kind of been the more prevalent one especially in the PUD’s so, but that flexibility of that and then whether or not there was hard cover so looking at how much hard cover would be added if you tried to enforce that sort of thing so right now people that are parking on their side or in their rear yard, typically that’s where you see the RV’s. They’re not always on hard surface and sometimes people put the rock on the side to accommodate that sort of need so those are some of the issues that we looked at too. And then the four was the size. Again an RV is a lot different than maybe a fishing boat. Looking at that sort of thing again. Looking at the setbacks to make sure that that’s being accommodated so you’re not creating a sight line. In addition to that you know there are a number of subdivisions that are governed by a homeowner’s association. Those homeowner’s association also regular outdoor storage but the City does not enforce those sort of things so this did not supersede that. Any HOA would have preference over that. So again staff believes that the limits, the indirect limits creating those vehicles would be in the front line. Addressed some of the concerns regarding sight lines and the hard cover and the like so just outdoor storage in general. Again people in the summer, they’re in, they’re out and some of it for the staff is that if you get a complaint you go out there and then Chanhassen Planning Commission – November 17, 2020 3 the neighbor says well I had it out for a couple days and it’s back in. Sometimes it’s a little hard to enforce to stay on top of those kind of issues. So many other cities permit outdoor storage in the driveway and prohibition again as I mentioned is difficult so the proposed changes would kind of make a more common practice within the city and still allow some outdoor storage. So as a part of this exercise MacKenzie Young-Walters on our staff who wrote this ordinance surveyed a number of other cities and looked at what they do and everybody, it’s kind of all over the map. Some don’t allow any. Some say seasonally and the number. Typically limits for the number of vehicles. The type of vehicles. The length of the vehicles. The height of the vehicles. Curb setbacks. Demonstration of viable alternatives so if you have nowhere else to put it then you could put it in the driveway. And then the required side setback. Again typically there must be, meet the building setbacks so, so it wouldn’t project if the garage is the, or the fence is the furthest point going forward then it couldn’t exceed that so then the number of vehicles. Some had no limit and some had limits on the numbers of vehicles and then permitted surface. Whether or not that was improved surface or unimproved. Again that’s one of the things that we run up against to. A lot of times people are parking them on the side yard want to put some sort of improved surface for them so that came into play so again while this is good anecdotal information every city kind of reflects their unique attributes. Whether there’s a lot of lakes in the community like we have in Chanhassen have a number of lakes and along for that so this proposed change would allow trailer and boat or recreational vehicle be stored in the driveway. It limits the property the storing a maximum of trailed boats or recreational vehicles. So if you had a, maybe a camper with a snowmobile trailer, you know fishing boat with some other type of trailer, looking at those sort of things as being part of the two. So includes boats and trailers and provision requiring stored items to be clean, well kept and operable condition. So and that’s the same process we do if there’s unlicensed vehicles stored in your driveway. Those are also, those would get a letter from code enforcement on that too if it’s unlicensed or inoperable so as not to be junky. So again prohibit the storing of extraneous materials within the recreational vehicles so again to be kept in slightly. You know maybe there’s like a topper on, or the like so the proposed code amendment represents a change to the highly visible long standing city ordinance so we really wanted to make sure that we raised awareness of this. We put an ad in the paper. It’s been out on our Facebook and then we wanted to make sure that we had the opportunity for a lot of feedback to provide comment on a number of social media platforms. So we did received some feedback. I’m not going to try to read the whole thing so but we did receive I would say it’s 60/40, 50/50 it’s pretty close so the first comment came in before we met tonight so it wasn’t actually formalized yet so…that person may want to speak. So the next one would be from Grover, Jeff Grover against the proposed changes. Many people have too many cars in their driveway already and so then there’s the Jeff and Barb Piesheck against the changes. If not enforced maybe it could look awful. People…relatives, friends maybe they might store their boats there so it’s kind of different like when you store maybe a docking rights it has to be in your name. The boat, you can’t be leasing out your storage space. I guess that’s kind of what that concern might be there so then the comment from Ms. Simpler, enforcement difficult to comply with, unfair enforcement. Difficult to comply with existing and we would concur with that. I mean it is hard right now to enforce you know if someone sends us, a typical process is we would send out a letter that says you’re in violation. You get so many days to rectify the Chanhassen Planning Commission – November 17, 2020 4 situation and maybe the boat’s moved but not for long and then it comes back so, so then McRyan’s support the change… Steven Brown…damaging landscaping. That’s another problem we talked about. If you have shrubs or trees or something and you’re not going to get your storage in the side yard so they are not looking… Mary Jane Olson. Against the policy change. Already complained that there’s a lot of driveway storage in neighborhoods that can change the property values and aesthetics. And that’s the one complaint we get right now when someone’s having maybe a graduation party or wedding group and they don’t want to have to do their group to have to look at the outdoor storage. Then…someone supports ordinance. Change to allow boats, trailers, recreational vehicles be stored in the driveways even in the summer. Then Jeffrey Williams absolutely not. Each one has some…regarding this. Chanhassen…should the ordinance change so our property values, you could add garbage cans to out of sight too. We do try to enforce that. That’s another that is difficult to enforce. People put them out in the morning. Go to work late that night so that is, they don ‘t pick up the next morning. That one too we’re supposed to be behind. That’s one we do enforce. To go back to the other comment about long time to change. This is something if the council did choose to act on it that we would really do a large media launch on this and talk what the rule change would be. If it didn’t change you know talk about we didn’t or the council didn’t change it to make sure that people understand that. Doug Peterson, don’t see a modification with staying in place at this time in relations to outside storage. Allen Nickolai, the less government intervention the better. Pete Keller enforce the current ordinance. It’s meant to keep our neighborhoods looking nice. Krissy Erwall. Outdoor storage in the winter sure. Outdoor storage if used, outdoor storage junk in back yard and we do get that complaint too. Sometimes people put an RV or boat in the back yard and that can also be unsightly. Sometimes someone’s back yard might be somebody’s side yard so. And then the last one we got today was from Alan Goshen. I personally think that if the resident wants to store their boat and trail, RV in their driveway, that’s perfectly fine. I prefer to see the alternative of putting them on the grass next to the house. I’d like to see the residents move at least to the side of their house if the driveway allows for it these objects move to the side of the house as much as their driveway allows and again that’s sometimes the length of the side yard isn’t large enough then that’s something we could take into consideration then that maybe they shouldn’t have it there so these are all factors that we thought about too. You know maybe it doesn’t make sense so with that we went through, I’d take any questions on the ordinance itself before we open up the public hearing but what I would recommend then is opening it up for comments but before we do that I’d be happy to answer just any general questions that the Planning Commission, just general questions on the ordinance and then we would, yep. Weick: Yeah the public will be just in a minute. I’m going to open it for Planning Commissioners if there’s any specific that you would like clarified about the code change with Kate we can do that at this time. And I think I’ll give people a chance. I’ll start. Can you clarify the before and after position on duration so long things can be stored on the property? Aanenson: Well the duration, there is no limit on that. Weick: There is not, okay. I just wanted it clarified. Chanhassen Planning Commission – November 17, 2020 5 Aanenson: So right now if it’s on the site so, that’s the way they’re supposed to be. So if you take it out of the lake it’s supposed to be in your side yard. Sometimes people say they’re going to go out again in a couple of days so that’s kind of that chase that we’re always making and that’s where the complaints come in. It’s like well why do I have to put it away when I’d be out again in 2 days. Weick: And we’re not proposing a change to that policy moving forward? Aanenson: Right. What we’re saying is you could have it parked in the driveway, yep. Weick: Right, okay. Any other, any questions or clarifications specifically on the code? Reeder: Mr. Chairman what’s our position on the hard surface? Weick: We do not have a requirement. Aanenson: Correct. We do not have a requirement that that be on hard surface. I think some people are reticent to take them off the driveway because they don’t want to park it in the grass so therefore often they’ll put rock or patio blocks or the like to get a hard surface on the side or the rear yard so they’re not parked on the grass. And it’s easier to get it out in the spring. Weick: So there’s no, there were no requirements for hard surface before or after? Aanenson: Correct except that we would assume that the driveway would be the hard surface. Weick: I’m sorry, yeah. Aanenson: No worries. Noyes: Commissioner Noyes here. Is there any requirements related to setback from the property line from a neighbor’s property? Aanenson: No. That’s a good question. So right now if you’re in your side yard setback there is none so I think that sometimes is a rub depending on the location. So the proposed ordinance says you have to, you can’t be over that property line. The sight line. Currently if you put it in your side yard that’s the one thing that there’s no natural setback from. If you were to put any other structure, a deck or something like that there would be a setback because was viewed back in the 70’s as temporary and has never evolved from that. It could be a while for the winter. Weick: But there’s a front yard setback for the driveway. Chanhassen Planning Commission – November 17, 2020 6 Aanenson: It goes with this one correct and that’s for sight line purposes, correct. Reeder: Mr. Chairman Commissioner Reeder. Tell me again what you just said about the side yard and the front yard. Aanenson: So there could be a front yard setback. So limiting that. The storage. The length of a vehicle would be affected so they’re not exceeding the front yard setback. But currently today if you wanted to park a boat in your side yard there is no setback. So if you had 10 feet and your boat width was 9 ½ and you could fit it in there, that would be permitted. Reeder: In the front yard. Weick: In the side yard. Reeder: Side yard. Aanenson: Yep. Reeder: But what is being proposed you could put it in the front yard in the side yard setback. Aanenson: No. Just in the driveway on the front yard setback. Reeder: I’m sorry, I can put my boat beside my driveway in the setback or not under the proposed? Aanenson: The proposed allows you to put it on your driveway. So you’re on a hard surface. You’re on your driveway so it’s easier for you to get it in and out to use. Not having to back it up, put it into your side yard. Reeder: So you’re saying you cannot put it in the side yard. Aanenson: The goal is to allow you to put it in your driveway, correct. Weick: I’ll give it a shot. As it stands today you can put a trailer, RV, boat in your side yard if it does not protrude past the front of your house so it can’t stick out past the front of your house and it can go as close to, there is no setback rule so it can go as close to your side yard property line as long as you don’t go over that, right? So if you have 10 feet on your side yard, Kate’s point was you could put a 9 ½ foot trailer there wide but you couldn’t put a 10 ½ trailer because you’d be into your neighbor’s property at that point. With the new proposal that doesn’t change. So you can still store trailers and RV’s that way or you can put them in your driveway. The setback for the driveway is from the street so there is a, every property has a front yard setback. It’s usually 10 feet and I’m guessing ish so you cannot encroach, so you couldn’t park your RV or trailer within that 10 feet of the street roughly, and don’t quote me on that but it’s roughly 10 Chanhassen Planning Commission – November 17, 2020 7 feet. So you couldn’t have it real close to the street where people couldn’t see potentially if they were pulling out of their driveway or something. If a neighbor was pulling out or if there was a sidewalk, you can’t block the sidewalk. Aanenson: So the language that we’re proposing is on page 11 of the staff report and so what we’re saying is that, just as you said Chairman, it allows you the additional opportunity to park it in your driveway but so what we struck out is the old, it used to say you could only put it in your side and rear. That’s the only place it could be stored. So now we’re giving the flexibility to put it on your driveway. We’re not saying you can add additional hard cover and put it on your side yard. If you want to continue to use your side yard because that’s obviously out of sight, that’s your choice but it does allow you the opportunity to store it on your driveway. Reeder: Mr. Chairman, Commissioner Reeder. Weick: Yeah. Reeder: Why are we not allowing it in the side yard setback next to the driveway? Aanenson: In the front yard? Reeder: In the front yard. Sitting next to the driveway where mine is. Aanenson: Well we felt it was probably more sight aesthetic when you’re pushing it closer to someone else’s property in the front yard as opposed to behind the house where you don’t have the line of sight. So I think part of the challenge there too is, by default it creates what you can store on your driveway. So if you put your RV and your additional off to the side in the front and you can still put 2 or 3 cars in there so it’s, having a boat or trailer there it’s limiting the capacity so it’s kind of a capacity issue. So it comes down to aesthetics too. Reeder: The problem is if you put your boat or trailer in your driveway you can’t get your out of the garage. Aanenson: Correct. That’s what I’m talking about it’s a capacity issue, right. Reeder: So essentially you’re not allowing them to store it in the driveway. Weick: There’s going to be potential limitations with several different types of properties. There could be driveway limitations. There certainly could be side yard limitations. We have a lot of different types of property designations that have very small side yards and side yard setbacks. That’s a limitation right? They can’t put trailers on the side of their house because it’s not wide enough. And unfortunately those conditions exist. I think we’re doing our best to try and talk about proposing something that you know potentially helps, you know helps the Chanhassen Planning Commission – November 17, 2020 8 situation. Certainly if we’re not helping it then we should consider that as well. But yeah it certainly isn’t going to solve it for every home and for every situation. Von Oven: Just another clarification point I guess. Where do, where would personal watercraft fall under this definition? Is that a boat? Is it a recreational vehicle or is it not covered by this language? Aanenson: The way…boat or a trailer in the city code. Von Oven: Okay so we would say a pwc is a boat? Aanenson: Yes. Von Oven: Okay got it. And then this is a really dumb question but I’m going to ask it anyway. Because boats and trailers are called out separately, if one has a boat on a trailer is that two? Does that now make the maximum that they are allowed to store? Aanenson: No. Von Oven: So a boat trailer combination is one. Aanenson: Correct, that is assumed. The same as a snowmobile and a snowmobile trailer. That would be, yep. Or it could be a trailer with some canoes on it. That would be considered the one. Von Oven: Got it, okay thank you. Weick: Commissioner Randall it looked like you were trying to say something before. Randall: I had the exact same question. I do have a question about enforcement. Who determines if a vehicle is operable or not and how is the code enforced? Aanenson: Yeah so that’s how we’re enforcing vehicles right now. So typically those are complaint basis. Maybe it hasn’t moved all summer and so that would just be an inquiry. Or maybe it’s been sitting there for 2 or 3 years and hasn’t moved so that would be complaint driven. Randall: Okay. Aanenson: Just to be clear I said that in the beginning too. We don’t have the staff to go around and driving looking for those kind of things so just like any other, trash being left out or something, those are all complaint driven. Chanhassen Planning Commission – November 17, 2020 9 Weick: Anyone else right now for Kate? Okay great, we will have a chance again to talk. Do not worry but at this time I would like to open the public hearing portion. Kate did summarize the emails and/or calls we received prior and thank you Kate for that. That was very helpful. At this time anyone present who would like to come forward and offer an opinion on this item please do so. Just state your name and address for the record and then I would ask that you, there’s plastic over the microphone and just talk as loud as you can so everyone can year you. Joe Perttu: Testing? Keep the mask on? Weick: That’s your choice. That’s fine. Joe Perttu: Good, good. Thank you for the opportunity to talk. My name is Joe Perttu. This is my wife Connie. We live at 681 Sierra Trail in Chanhassen. 681 Sierra Trail so we overlook Kerber Pond and it’s funny to me that the person that actually created a lot of these complaints isn’t even here right now I mean to address why you know he felt like it was his duty to complain because obviously this is complaint driven. That’s the way that I was told that after 15 years of living here that we have to move our boat off the driveway. I had some notes here I was taking. Can you continue to talk? Connie Perttu: Well I mean our’s has always been in the winter, we have a storage place for it in the winter but in the summer you know it’s like, we have like a 3 wide driveway but a 2 car garage so in that third area is where it’s stored. Joe Perttu: And it’s improved. It’s tarred. Connie Perttu: And we have a, you know it’s always clean in perfect shape and has a cover on it and everything too. I mean it’s never been an issue there. Joe Perttu: Also I’d like to add that in the winter time we do store it somewhere else so it’s not on the driveway. I understand the situation where people don’t want all kinds of clutter. I think we all are here to make sure the city stays beautiful and we’re not over using it with old rickety junk that doesn’t work so I mean I think the establishment does some guidelines of that car ought to be usable or off the driveway for at least a portion of the summer. I think we can all agree that that’s reasonable, right. So for me it’s a financial issue too. Like I say when, if I was not able to keep my boat on the driveway I mean it costs me about $400 to have it stored for the summertime and it’s far less convenient to use and you know recreational vehicles are, they’re to be used and hopefully you can get them out without having to take a drive for 10 minutes or so. I want to make sure that you understood that I have improved property. Improved surface. Again 3 stalls. We have that third stall for this particular purpose. To park a boat and we happen to be one of those homes that do not have enough of a side yard. It’s not like I have a cruiser boat that is ready for the ocean here. We’re talking about a 19 foot boat. Just a regular fishing boat but it’s like 9 ½ feet wide at the base of the trailer and I’ve got like a 9 foot 8 inch side yard and it ain’t going in there that’s for sure so thank you for your patience but I just wanted to let Chanhassen Planning Commission – November 17, 2020 10 you know there’s financial impacts to these families that would have to move their vehicles off the driveway and I find it nonsensical. Again we’ve been here for 15 years and we have a very nice home and none of our neighbors are complaining about my boat on the driveway so. Connie Perttu: I just have one quick question on this as well. Is there a limit to how many cars can be in the driveway? Are those conditions of the cars that are there? Are there any of those codes? Aanenson: No. Connie Perttu: I’m just curious, okay. Aanenson: So just to be clear this is allowing, this ordinance amendment allows to keep your boat in your driveway. Connie Perttu: Yeah, right. Just checking to see… Weick: And cars are not included. Aanenson: Cars are not included. Connie Perttu: How many cars someone wants in their driveways. Aanenson: That would be a nuisance if they’re blocking or sight lines, yep. Connie Perttu: Got it. Joe Perttu: Thank you for your time. Weick: Thank you very much. Anyone else wishing to come forward. Just please state your name and address and talk loudly into the microphone if you can. Mary Olson: Hi, I’m Mary Olson. I live at 7461 Windmill Drive. Weick: Welcome. Mary Olson: I’ve lived in Chanhassen at this current location 26 years. We were one of the neighborhoods that had the covenants where we had our own bylaws and for the most part everybody followed them and they over the years have kind of gotten lax. Disappeared. People have moved, moved out, never saw the covenants and I get that but we’re very concerned about our neighborhood and the way that it looks and I understand it’s an issue trying to get around and enforce this but I think it’s very important because we already have a lot of people that are taking advantage of it or you wouldn’t be getting the complaints and I appreciate the way that you guys Chanhassen Planning Commission – November 17, 2020 11 are handling it with your boat and you have a nice boat and you have it clean and you keep it in a hard surface area and, but not everybody is that responsible and we currently have people, you talked about the garbage bins. They’re not just left out overnight. They’re there every day, every night, always because that’s where they keep them and there’s the recycling bin. The garbage bin. The yard waste bin. Then we’re now going to let them have 2 boats. Most of them have 3 vehicles so those vehicles are going to end up in the street so that they can come and go and I’m just very concerned about the people, unfortunately we’re not all responsible and you always have the ones that push it and I’m not saying we need to complaint about everybody and everything that they do. We have to get along. I understand that but there also has to be some way to kind of push responsibility on the ones that take advantage and that’s my concern. Thank you. Weick: Thank you very much. Anyone else that would like to come forward may do so at this time. I don’t know if we want to show the phone number as well. We have the phone number up as well. We’ll just give that a minute. I’ll take that time to say thank you to everyone who took the time to come in this evening and meet with us, especially with the health issues and everything like that. I can speak for the entire Planning Commission when I say that I don’t believe that there’s a more important voice than the voice we hear from neighbors and residents on issues, especially issues like this. It’s something that we were talking about earlier and we all, you know we all have opinions but it’s so important to hear everybody’s opinion and to really weigh that heavily. Especially if we’re thinking about making a code change. So thank you and thank you to everybody who emailed or called in prior as well. With that the phone’s not ringing so I will close the public hearing portion of tonight’s matter and open it up now for commissioner discussion and comments and/or motions. Skistad: Commissioner I would just like to confirm that I believe that there’s covenants already in the neighborhood that this does not supersede the covenant so if a neighborhood has bylaws set up they still follow their bylaws so I just wanted to, that’s just a point of clarification. Aanenson: That would be correct, yep. Weick: As we’re thinking about this I jotted a couple notes that I ask the commissioners to think about. You know it’s a big decision to make a code change obviously and I would say consider you know in your opinion do you feel like we’re improving the situation or the physical appearance of the city. I think that’s an important thing. That’s something I was considering as I was reading through this is, you know we want to be sure that we’re not doing something that is detrimental to the overall appearance so I would ask you to keep that in mind as well. You know that being said I think you can make, I mean I’ve seen boats and RV’s stored around the city in a lot of different ways. I’ve seen them look really good in driveways. I’ve seen them look not so great in driveways. I’ve seen them look really great in the side yard and I’ve seen cases where I’m like wow, I wouldn’t want to look at that in my side yard right so I think that that scale can go either way as far as aesthetics are concerned. I’m just kind of thinking out loud but hopefully that helps as you think about this item. Chanhassen Planning Commission – November 17, 2020 12 Von Oven: I know in the report it said we don’t have the staff to proactively monitor. Do we have stats on in a given year how many, I don’t even know what to call this but how many front yard boat related complaints we receive that we then react to and try to deal with? Is that a weekly thing? Is that a monthly thing? Is that everyday? Aanenson: Not everyday. I would say there’s probably one every week or two for sure, yeah. Audience: With different people or? Aanenson: Yes. Yeah. Weick: Maybe as people are thinking about this and thinking about if they want to read a motion or not, I will, I’ll walk through what are kind of the six areas that were laid out in the report and as I understand it what the revision to the code would include. The first was driveway. Right now we do not permit RV’s or boats and trailers in the driveway. Under the code amendment we would allow up to one in the driveway. As it’s written. Aanenson: Up to two. Weick: Up to two as it’s proposed. Aanenson: Correct. Weick: Okay, thank you. Kind of was wrong on that. For side yard setbacks there’s no side yard setback other than what the property line that exists today and that would continue. We do not have any requirements for the surface to be finished underneath the vehicle or the trailer and that would move forward except the understanding that a driveway is finished, that’s an assumption. Aanenson: Correct. Weick: There’s no change, there are no size requirements today and there’s no change to that. This is one I probably need your help on Kate. The number of vehicles, as I understand it right now is unlimited. Just RV’s and boats and trailers. Aanenson: Two. Weick: It is two today? Aanenson: No, now that’s unlimited you’re correct. Weick: It is unlimited and it would be going to a maximum of two. Chanhassen Planning Commission – November 17, 2020 13 Aanenson: Correct. Weick: Okay. And then there’s no change to the duration. Aanenson: And then just to clarify again, you kind of said this but this is to Commissioner Reeder’s comment. So you can still park in the side yard but you can’t go past the front yard setback. So if you still choose to put it in your side yard, some people have hard surface on the side…but you can still continue but you can’t move it to the front of the house and put it in the side yard. It can’t extend past of the house. Weick: Which is no different than today. Aanenson: That’s exactly right so that wouldn’t change. So you could still continue to put it on the side. Von Oven: So just to clarify Commissioner Reeder is currently breaking the law. Weick: Don’t make this more difficult. So on the first thing I’m going to kind of throw out maybe the first curve ball to this but when you think about the driveway I’m just posing a question to my fellow commissioners. Would it make sense to limit the number of vehicles in the driveway? Does that make any difference at all in your opinions? In other words it’s one thing, you know one RV or trailer in the driveway and then somewhere else. That would be your two instead of two in the driveway. I don’t know. I’m just asking that question. Von Oven: I’m glad you asked the question actually because I was under the understanding that that’s the way the code is currently written. So if I’m page 11, Section 4, Part A, one impacted vehicles in the driveway and then I read it to say Part B says they can also be stored over there but somewhere along here there’s a maximum of two. So Part 4(A) to me says that only one can be in the driveway. Aanenson: That’s how it’s written, that’s correct. Von Oven: Okay. So I believe that from the way I read it there is a one vehicle, boat trailer limit in the driveway and then if I have another one and I want to throw it in the back or on the side yard as long as it doesn’t protrude into my neighbor’s yard then that’s okay so I think that limit actually already exists. Weick: Okay, thank you for that clarification. Maybe that’s where I remember it from. Okay. Audience: Are we allowed to speak at all? Weick: We’ve closed the public portion. Chanhassen Planning Commission – November 17, 2020 14 Reeder: Mr. Chair? Weick: Yes sir. Reeder: I think we’re not solving the whole problem that I see here. There are in my estimations a number of recreational vehicles, boats or whatever on the side yard in the front yard now and at same time we’re trying to deal with the problem that there are people parking in the driveway. I would argue that there are a similar number of people that are parking on the side yard in the front of the house and there are houses that have no side yard possible to on their side of the house so I think that we should allow whatever number we agree on to be parked also in the side yard in the front yard. Weick: If I could just get clarification on that. You really mean front yard. You don’t mean side yard, you mean the front yard. Aanenson: All the way to the property line. Reeder: I mean in front of the house in the side yard. Off the driveway. Do you understand? Weick: I guess yeah. And I think that would be, I mean today that’s not permitted and I think it would not be permitted in the new code either. Aanenson: Right and that’s what he said. Reeder: With that I would suggest that we should change it and I might offer that amendment because I think you’re only solving part of the problem that staff is trying to deal with. They will be able to get rid of all the non-conforming vehicles that they have that are now also on the side of the driveway in the front. Weick: Okay. Any other thoughts on that point from Commissioner Reeder from other Commissioners. Von Oven: I think I would maybe offer a different opinion. I think while there’s probably no perfect code amendment that is going to solve this problem perfectly in every single person’s best interest, I was really impressed by everything that this hit on the way through. Everything from not making people create more paved surfaces so that we live in a concrete jungle but limiting the number of vehicles that could actually be put in the driveway to one when it comes to these boat and trailers and RV’s. I think expanding it to say go ahead and put everything in the front yard whether it’s on the side of the front yard or in the driveway or in the middle of the front yard I think that creates a little more mayhem for, I forget who said it but the people who are not really conforming. The people who don’t have things kind of put together and they want it on display in the front yard so I would not, I would not be in favor of expanding it to the rest of Chanhassen Planning Commission – November 17, 2020 15 the front yard. I think the whole point of all of this is trying to keep things in your own yard. Out of the view of your neighbors but we’re going to allow one in the driveway. You know if I think about how many calls we’re getting a year and now I’m just going to make up statistics because we don’t know but if we’re getting a call a week right, what are the chances that all 52 of those are for somebody’s boat that is on the side of the driveway versus in the driveway right, so I disagree that we’re not going to be solving any of the problem. I think this actually will solve a lot of the problem. It’s still going to leave something to be desired but I’d be open to ideas of how to perfectly solve this so I am in favor of what’s being proposed here. I know there will be some push back but I think, if I think about the best way to allow what we should be allowing people to do on their property without creating mayhem in the front yard, I think this is a nice balance that along the way as this goes to City Council might there be an amendment to it that makes it even better? Maybe but I think it’s a really, really good start. Weick: Thank you. Skistad: And I would second what he said. I agree with him. I thought MacKenzie did a fabulous job writing this up and listed all the issues and it was very clear overall why we’re looking at the changes and some of the best ways to go about that. Aanenson: If I may Chairman, I think one of the things we talked about internally is this is a big change and so we want to, you can start an ordinance on a certain date so we anticipate maybe this is the summer. We started at the end of the summer, we spend some time because there are people that are non-conforming and have been for a while. So to, so we could start that adoption at a later date but spend the summer educating people the direction, the general direction that you choose to go and try to get compliance and conformance and explain all that. Noyes: Chairman, Commissioner Noyes. I would also agree with Commissioner Von Oven. I think the word that he used that I think really kind of epitomizes this is balance. This isn’t going to be perfect but I think we’ve got to balance the needs of the people who have the boats and the RV’s and whatever to store with the views of the neighbors in that neighborhood. There’s many more people that are not storing things in their yard than there are and some of those people are not real happy about you know their neighborhood having a different look because of all of this but I also think we’ve got to make sure that we have solutions for people that do have these things and I think the way it’s set right now is I think that balance is struck pretty well and would be against expanding this so that the front yard was included in it. I think that would start to really kind of change what we’re trying to do here and I think push the balance too far in one direction so that’d be my comment. Weick: Thank you. Randall: Commissioners I also feel the same way. I feel maybe some comments about the balance. These were really good. People that know me know that I believe in personal property rights. However there are, this is a good balance. It allows for people to still have these items in Chanhassen Planning Commission – November 17, 2020 16 their driveway. It’s just not wanting to accumulate to the point where it becomes a problem so I think it’s a good balance for the neighbors that have to look at this stuff and also to that these people who want to have these items also. That’s all I’ll say. Weick: Thanks Commissioner Randall. Sounds like we’re working towards a decision which is nice. I think balance is hard. We’re taking the harder route having to get to this point. I think it’s easier to say all or nothing you know, those are easier things to do. I think it’s much more difficult to try and reach a balance. And I will admit I struggle. In one minute I think awesome and then in the next minute I think what are we creating but I think at the end of the day there’s a situation that already exists here and I think we’re, I think we’re trying to help. I do. Von Oven: So here’s what I would offer for folks who may not know. So we’re the Planning Commission and as you said right we have the opportunity to take what MacKenzie has created and move it forward to City Council but we’re not the end all to be all. So at the end of the day the City Council has to vote on this and as much as I think we have an important role to play, I think people pay a lot more attention when things go to City Council than when they come to Planning Commission so it’s my hope that if we as a council approve this, or recommend this tonight and it goes before City Council it will get a bit more attention and it’s also my hope that people will offer potential amendments to even make this better. I’m fine personally with it as it is but as a city we might be able to group think our way to a slightly even better motion so with that I would offer a motion. That the Chanhassen Planning Commission recommends that the City Council adopt the proposed amendments to Chapter 20, Zoning of the Chanhassen City Code concerning the outdoor storage of boats, trailers and recreational vehicles. Weick: We have a valid motion from Commissioner Von Oven. And do we have a second? Randall: I’ll second that. Weick: A fervent second from Commissioner Randall. Before we vote I give anyone a chance to offer any last opinion for the record. I would say that I don’t believe we are suggesting any changes to what’s been written and proposed by staff. I guess that’d be one of the purposes that we have which is, is there anything that we found that we would like to see added or changed from the new code as it’s written and so I think we’re by offering this motion we’re saying you know we’re good with this code kind of moving past this step in the process. So we have a valid, anyone else? That was really rude. Is there anyone else that would like to make comment about the item before we vote? Reeder: Mr. Chair? Weick: Yes sir. Reeder: I’m going to vote for this motion because I do agree with staff that this moves in the right direction. My thought was that it could move even a little further but I think that’s Chanhassen Planning Commission – November 17, 2020 17 something that we could take up maybe several years after we see how this change goes. And just for the record I wasn’t proposing that we put vehicles all over the front yard. I was only suggesting that the area between the driveway and the side yard setback next to the driveway could be used to allow somebody to be able to fully use their driveway for what it was intended for cars, and also get their recreational vehicle in a place that they could use it so I will support it but I think it could go further. Weick: Thank you. And to Commissioner Von Oven’s point as with all the comments that have been made tonight. They are part of the record. That record is reviewed by City Council in detail and that point could be one you know that is reviewed and possibly added at the City Council level so thank you for that. Anyone else with comment before we vote? And hearing we’ll do a roll call vote. Von Oven moved, Randall seconded that the Chanhassen Planning Commission recommends that the City Council adopt the proposed amendments to Chapter 20, Zoning of the Chanhassen City Code concerning the outdoor storage of boats, trailers and recreational vehicles. All voted in favor and the motion carried unanimously with a vote of 6 to 0. Weick: So the item will move forward to City Council with a unanimous recommendation of 6 in favor, zero against. Again thank you to everybody on the commission, staff, residents who came tonight to voice their opinion as well as those residents who emailed and called in prior to this meeting. That is the most important part of this. This isn’t difficult and I do feel comfortable that we’ve passed something to City Council with good research and good opinion so thank you. APPROVAL OF MINUTES: Commissioner Noyes noted the verbatim and summary Minutes of the Planning Commission meeting dated October 20, 2020. ADMINISTRATIVE PRESENTATIONS. Weick: And Kate do you have a City Council update? Aanenson: While I’m looking for that I was also going to give you an update on your next coming agenda. We actually have 3 items on the next agenda. We’ve got a rezoning for a piece of property that wants to do a PUD. We have a subdivision. I think we talked about that before. Deer Haven on Yosemite and then the final one is the, this auto repair business at 101 and Lyman Boulevard so it’s a 10 day. Sharmeen Al-Jaff on our staff worked really hard to get really nice architecture on that and so they did resubmit. They asked to be tabled so I think it’s a much better drawing. So City Council update. Here we go. So the Bluff Creek, the Bluffs at Lake Lucy there was a restriction on Saturday work hours so that was modified and then they approved the preliminary and final plat for the Berrospid. That one that you saw. The City Council did approve that. There was some discussion on that. I think a little bit more than Chanhassen Planning Commission – November 17, 2020 18 maybe even so the owner of that property actually does a lot of commercial development so he was very knowledgeable on actually had done to the watershed district. Very knowledgeable on the stormwater containment and that was really the driving… He originally was going to do two lots but the complex water treatment that was done so he’s used to installing those so I think that was a great conversation so that project will be proceeding forward. And so as I mentioned we have 3 items on your agenda then for your last meeting of the year, December 1st and we already have a couple of projects in the queue for January so that’s all I had Chairman. There’s open discussion after close the meeting regarding potential commission vacancies and what to look for in making new commissioners so we’ll discuss that when we close the meeting. Weick: Tonight? Aanenson: Yes. Just for a couple minutes, yep. So if everybody stays online. Weick: I don’t know if you heard that but please stay online but with that I would entertain a motion to adjourn. Von Oven moved to adjourn the meeting. All voted in favor and the motion carried unanimously with a vote of 6 to 0. The Planning Commission meeting was adjourned at 8:00 p.m. Submitted by Kate Aanenson Community Development Director Prepared by Nann Opheim
