LOCATION: 3800 Red Cedar Point Road OWNER AND APPLICANT: Richard Comer 3800 Red Cedar Point Road Excelsior, MN 55331 PRESENT ZONING: Single Family Residential District, RSF 2030 LAND USE PLAN: Residential Low Density ACREAGE: Gross: 1.062 acres DENSITY: Gross: 1.88 units/ac Net: 1.062 acres Net: 1.88 units/ac LEVEL OF CITY DISCRETION IN DECISION-MAKING: The city’s discretion in approving or denying a Preliminary Plat and Final 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. The city’s discretion in approving or denying a Variance is limited to whether or not the proposed project meets the standards in the zoning code for a variance. 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. PROPOSED MOTION: “The Chanhassen Planning Commission recommend that the City Council approves the preliminary and final plat for a two-lot subdivision and approves a lot frontage variance for Lot 1, Block 1, Comer Addition as shown in plans dated December 5, 2018 subject to the conditions of approval, adopts the findings of fact and decision, and adopts the attached resolution. recommendation.” (Note: A motion for denial and appropriate findings of fact are also included at the end of the report.) 3800 Red Cedar Point Road February 5, 2019 Page 2 PROPOSAL/SUMMARY The applicant is proposing to subdivide the existing lot to create two lots for single-family detached housing. The northern lot will have an existing non-conforming single-family home and the southern lot will be unencumbered. The applicant will request that the City Council concurrently approve the preliminary and final plat. The applicant is also requesting a variance from the Single Family Residential District’s required 90-foot minimum lot frontage. The applicant could meet the required 90-foot lot frontage for both lots using a diagonal rear lot line; however, this would result in sub-optimal lot configuration and accessing the parcel through this frontage would be impractical, as the right- of-way is unimproved. The existing home is currently accessed via a driveway easement north to Hickory Road and the applicant proposes retaining that access. The applicant is also proposing that the northern lot line be designated as the front line for Lot 1, Block 1 in order to align the lot’s orientation with its access to the public right-of-way. Access to the proposed southern lot is provided by Red Cedar Point Road and access to the proposed northern lot is provided by a driveway easement to Hickory Road. Sewer and water are available to the site. Staff is recommending approval of the request. APPLICABLE REGULATIONS Chapter 1, Sec. 1-2 “Rules of construction and definitions” Chapter 18, Subdivisions Chapter 20, Article II, Division 3, “Variances” Chapter 20, Article VII, Zoning and water supply/sanitary provisions Chapter 20, Article XII, “RSF” Single Family Residential District Chapter 20, Article XIII, Division 1, Sec. 20-904 “Accessory Structures” Chapter 20, Article XIII, Division 1, Sec. 20-905 “Single-family dwellings” Chapter 20, Article XXIV, Division 2, Sec. 20-1122 “Access and driveways” BACKGROUND Site Constraints The existing house was built in 1928. The house is nonconforming due to the lack of a two-car garage and failure to meet the east lot line’s 30-foot front yard setback. The high point on the property is at the south most edge near Red Cedar Point Road with an elevation of 973. The low point on the property is along the north lot line with an elevation of 949.6. The existing lot has 148.2 feet of frontage along Red Cedar Point Road, 235.71 feet of frontage along Kirkham Road (platted only), and a lot area of 46,279 square feet. 3800 Red Cedar Point Road February 5, 2019 Page 3 The site has a net canopy coverage of 54% percent. This site is located within Lake Minnewashta and Lake St. Joe’s shoreland management districts. No wetlands appear to be present on the site. COMPREHENSIVE PLAN This area has land use classification of Residential Low Density in the city’s 2030 Comprehensive Plan. This classification requires net densities of between 1.2 – 4.0 units per acre. The applicant’s proposal has a net density of 1.88 units/acre, which is consistent with the area’s land use plan. ZONING ORDINANCE The property is currently zoned Single Family Residential (RSF) District, and the applicant is not requesting a change to the parcel’s zoning. The proposed subdivision would require a variance from the zoning ordinance’s minimum lot frontage. VARIANCE Sec. 18-60(a) of the subdivision ordinance requires that lots abut their full minimum frontage on a public or private street as required by the zoning ordinance and Sec. 20-615(2) of the zoning ordinance requires that properties zoned RSF have a minimum of 90 feet of lot frontage. The City Code defines the front lot line as the lot line separating a lot from a roadway right-of-way and further defines roadway as the improved portion of the right- of-way. This means that Lot 1, Block 1’s east lot line is the front lot line because it has only 12 feet of the 90 feet of required frontage along Hickory Road. The east lot line also has 35 feet of frontage along Kirkham Road; however, since Kirkham Road is not improved it does not 3800 Red Cedar Point Road February 5, 2019 Page 4 meet the City’s definition of a street. Finally, with the east lot line as the front lot line, Lot 1, Block 1 does not meet the 125-foot minimum lot depth required by Sec. 20-615(3) for an RSF lot since its average depth would be only 117.2 feet. The applicant has demonstrated that the subdivision could meet the lot frontage requirements of Sec. 20-615 using a diagonal lot line as shown in Concept B, though an 8-foot lot depth variance would still be required. This configuration is not preferred because it would require either the dedication of additional right-of-way and construction of Kirkham Road, resulting in approximately 5,640 square feet of impervious surface that the City would be obligated to maintain, or the construction of a private street resulting in approximately 4,700 square feet of impervious surface. A second alternative is that the applicant could also utilize a flag lot configuration to provide both parcels with access via Red Cedar Point Road. A flag lot would meet all of the requirements of Sec. 20-615, though it would require a variance for the use of flag lots as provided in Sec. 18- 57(r). This configuration is not preferred because it would result in the creation of at least 1,250 square feet of additional impervious surface within the shoreland management district. The applicant is instead proposing that the city recognize the parcel’s existing north-south orientation and the fact that access to Lot 1, Block 1 will be provided by the driveway easement to Hickory Road by designating the property’s north lot line as the front lot line. This designation would create a parcel with a minimum lot width of 108 feet, a minimum lot depth of 197 feet, and a total lot area of 23,239 square feet, significantly over the RSF district’s required 90 foot lot width, 125 foot lot depth, and 15,000 square foot minimum lot size. This approach would require a variance from Sec. 18-60(a)’s requirement that the lot abut its full frontage along a public or private street and a variance from Sec. 20-615(2)’s minimum lot frontage requirement, as the parcel would not have 90 feet of lot frontage. 3800 Red Cedar Point Road February 5, 2019 Page 5 Front Lot Line The City Code defines the front lot line as the lot line separating a lot from a roadway right-of-way. The lot line that separates Lot 1, Block 1 from a roadway right-of- way is the east lot line. In its current, pre-subdivision, configuration, 3800 Red Cedar Point Road’s front lot line is the south lot line; however, access to the home is provided by a private driveway easement to Hickory Road to the north. The applicant is proposing to maintain this northern access for Lot 1, Block 1 and have Lot 2, Block 1 access Red Cedar Point Road. The graphic to the right shows the surrounding properties’ directions of access, indicated by black arrows, as well as the applicant’s proposed directions of access, indicated by blue arrows. The applicant is requesting that the City designate Lot 1, Block 1’s north lot line as the front lot line in recognition of the parcel’s existing and proposed street access, orientation, and the general orientation of the surrounding parcels. The city may as part of a variance request designate appropriate house pad configurations. In this case the proposed designation of the north lot line as the front lot line will create a more typically sized building pad than the relatively narrow 48- foot wide building pad that would be allowed by applying the front and rear yard setbacks to the east and west lot lines. The proposed front lot line is not expected to negatively impact the surrounding properties as it represents a continuation of the existing conditions on the property. Due to the general orientation of lot and surrounding properties, proposed street access, and placement of the existing home, staff supports designating the north lot line as the front lot line. Sec. 18-60(a) The intent of Sec. 18-60(a) is to prevent the creation of landlocked lots by ensuring that all lots in the city have access to a street. It provides three mechanisms for this: 1) the lot can have the required frontage on a public street; 2) the lot can be accessed by a private street; or, 3) the lot can be a flag lot. The proposed subdivision is atypical in that the parcel has an existing street access that does not fall into one of the aforementioned categories. The parcel has a private driveway easement over the vacated portion of Kirkham Road that provides access to the existing house and will remain in effect after the parcel is subdivided. This private driveway easement is not technically a private street, but serves the same practical function by 3800 Red Cedar Point Road February 5, 2019 Page 6 guaranteeing Lot 1, Block 1’s access to the public road system. Since access to Lot 2, Block 1 would be provided by Red Cedar Point Road, the proposed subdivision would not increase the nonconforming nature of the parcel’s access. As has been noted earlier in this report, the applicant could theoretically utilize any of the three mechanisms provided by the city’s ordinance to access Lot 1, Block 1; however, all of these configurations would involve the creation of unnecessary impervious surface within the shoreland management district. Due to the importance of limiting the amount of impervious surface near the city’s aquatic resources and the fact that there is an existing access, staff supports granting a variance from the referenced lot frontage requirement. Sec. 20-615(2) The intent of the zoning code’s minimum yard width requirement is to ensure that lots can accommodate a house and two-car garage while meeting the district’s 10-foot side yard setbacks and to provide for adequate spacing between residential driveways. While the proposed Lot 1, Block 1 would not have 90 feet of lot frontage, its shortest lot line is 108.85 feet long, which is well in excess of the district’s 90-foot minimum. The proposed Lot 1, Block 1 has an existing non-conforming house and, if the house were retained, would have sufficient available lot cover and space within the lot’s buildable area to add a garage. In the more likely scenario where the house is replaced, the City Code provides guidelines for an assumed building footprint. Sec. 18-60(j) of the subdivision ordinance stipulates that a 60-foot by 60-foot building pad should be assumed when house plans are not known. Both of the proposed lots can easily accommodate the assumed building pads. 3800 Red Cedar Point Road February 5, 2019 Page 7 Regarding the spacing of residential driveways, the lack of 90 feet of lot frontage will not change residential driveway spacing within the neighborhood as Lot 1, Block 1 will continue to utilize the driveway it shares with 3737 Hickory Road. It should also be noted that many of the properties fronting Hickory Road do not have the required 90 feet of lot frontage so granting Lot 1, Block 1 a lot frontage variance will not materially alter the character of the neighborhood. The applicant could theoretically meet the lot frontage requirements, but all of those configurations require the creation of additional impervious surface within the shoreland management district. Since both of the proposed lots would exceed the RSF district’s minimum lot width, depth, and area and the proposed access for Lot 1, Block 1 maintains the existing configuration of the neighborhood, waiving Lot 1’s lot frontage requirement would not be expected to impact neighboring properties. Given that the proposed configuration of Lot 1, Block 1 would essentially maintain the existing conditions along Hickory Road and that the proposed lot dimensions can accommodate a the 60- foot by 60-foot building pad required by the subdivision ordinance, staff supports granting a variance from Sec. 20-615’s lot frontage requirements. PRELIMINARY PLAT SITE CONSTRAINTS Existing Home The property has an existing home that was built in 1928, and does not meet the zoning code’s corner lot setback or two-car garage requirement. Given the age and condition of the home, it is likely that the house will be demolished and replaced; however, it could be refurbished. In either scenario, the 3800 Red Cedar Point Road February 5, 2019 Page 8 subdivision of the property would not increase the existing non-conformity of the house and any improvements would need to comply with the relevant sections of the City Code. Concrete Pad There is an existing concrete pad located on the proposed lot line separating Lot 1 and Lot 2. If the property is subdivided in the location proposed by the applicant, it would result in the creation of a non-conformity, as the concrete pad would not meet the required lot setbacks. Staff is recommending that the concrete pad be removed as a condition of approval for the subdivision and that an escrow be provided to ensure that the concrete pad be removed. The applicant will be required to provide a cost estimate for the removal of the concrete and an escrow for 110 percent of the submitted estimate. Site Access The existing house has access to Hickory Road to the north via a driveway easement. The configuration of the parcel makes it undesirable for a home situated on the northern portion of the parcel to access Red Cedar Point Road. Once subdivided, Lot 2 would meet the subdivision ordinance’s frontage and access requirements along Red Cedar Point Road; however, as is discussed in the variance section of the report, staff believes that it makes the most sense for Lot 1 to be granted a variance for the city’s lot frontage requirements and to continue to be accessed from Hickory Road through the existing driveway easement. FIRE DEPARTMENT The Fire Department has noted that response to the site is currently complicated by the fact that the home is addressed as 3800 Red Cedar but has driveway access off Hickory Road. They are recommending that since Lot 1, Block 1 is proposing to retain access off of Hickory Road, it be readdressed to reflect this in order to avoid confusion. 3800 Red Cedar Point Road February 5, 2019 Page 9 GRADING, DRAINAGE & EROSION CONTROL Grading/Drainage The applicant is proposing to grade only within the limits of Lot 2. This grading will accommodate the construction of one new home on the property, which has been illustrated to the minimum standards set forth by city ordinances (as the house plans are not known, a 60-foot by 60-foot building pad and 30-foot wide access driveway were illustrated §18-60). The proposed grading will route stormwater drainage away from the building, indicated by drainage arrows on the plans. All grades have been proposed to meet a 3:1 maximum with no proposed retaining walls on site. No soils report or geotechnical study was provided within the submittal. The applicant will be required to provide an accurate soils report indicating soil conditions, permeability, slope, and groundwater elevations upon the submittal of grading permits. Erosion Prevention and Sediment Control The applicant has prepared and submitted a preliminary erosion and sediment control plan for the grading of Lot 2. The contact for the party responsible for maintenance of erosion control measures has been left as “TBD.” The applicant will be required to update the contact information prior to the issuance of grading permits. Furthermore, it is the recommendation of staff that silt fence be used as perimeter control around the entire site as an erosion control BMP. The applicant has proposed the use of both bio-rolls and silt fence for perimeter control. Review and approval by the city of the use of both BMP measures for perimeter control shall be conducted prior to the issuance of grading permits, and all city requirements for erosion control shall be met. Lastly, the applicant shall update the detail sheet of the plans to include the city detail for erosion control for individual lots (#5302B). STORMWATER MANAGEMENT The proposed development of Lot 2 should be designed to meet the city’s water quality and water quantity requirements. 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.” The proposed development will need to receive any and all required permits and meet the requirements of Minnehaha Creek Watershed District and Minnesota Department of Natural Resources. Stormwater Utility Connection Charges Section 4-30 of City Code sets out the fees associated with the Surface Water Management Plan (SWMP). 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. 3800 Red Cedar Point Road February 5, 2019 Page 10 This fee will be applied to the new lot of record being created. It is calculated as shown in the table below for the current rate in force for 2019: SURFACE WATER DEVELOPMENT FEE AREA PER ACRE FEE ACRES FEE GROSS AREA $8,320 1.06 $ 8,819.20 NET AREA 1.06 $ 8,819.20 The applicant shall pay the SWMP fee at the rate in force at the time of final plat approval. RIGHT-OF-WAY, STREETS AND EASEMENTS Streets, Driveways & Sidewalk No new public streets or walkways are required. Red Cedar Point Road provides right-of-way access to Lot 2, while access to Lot 1 is via an existing shared driveway access off Hickory Road. Red Cedar Point Road has an existing dedicated right-of-way of 50-feet abutting Lot 2. While this does not meet the city’s current 60-foot right-of-way requirements, numerous roads in this area have a non-conforming 50-feet of dedicated right-of-way and the city does not believe it will be possible to acquire additional right-of-way from the other properties south, east, and west of the proposed Lot 2. Therefore, no street right-of-way dedication will be required. EASEMENTS The applicant is proposing the dedication of 5-foot side and rear, and 10-foot front lot line drainage and utility easements around Lot 2. However, the applicant is proposing only 5-foot side, rear, and front lot line drainage and utility easements around Lot 1. As the north lot line of Lot 1 is defined as the front lot line, and due to the proximity of a public water main to said lot line, a 10-foot drainage and utility easement shall be provided on the final plat prior to acceptance and recording. UTILITIES Sanitary Sewer and Water Main No extensions of any public sanitary sewer or water main trunk lines are required. The existing home on Lot 1 will continue to use the current water and sewer service from Hickory Road. The newly created Lot 2 will have access to water and sewer service from Red Cedar Point Road via an existing 10” HDPE water main and an 8” PVC sanitary main. From city records and tie- cards, there was a PVC sanitary sewer and 1” copper water service stubbed in 1974 to the proposed Lot 2 off Red Cedar Point Road. The applicant will be required to field verify the location of these service stubs and assess their serviceability prior to the issuance of building permits. If the sanitary and water services are inadequate for use, they shall be abandoned in accordance with city standards and re-installed. As these service stubs have never been utilized, the development of Lot 2 will be required to pay all required city WAC and SAC fees associated with service connections at the time of the building permit application. 3800 Red Cedar Point Road February 5, 2019 Page 11 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. For 2019 rates, the partial hookup fees are: a) A portion of the water hook-up charge: $2,311.00/unit b) A portion of the sanitary sewer hook-up charge: $691.00/unit The remaining partial hookups fees are due with the building permit. The remaining fees for 2019 are: a) The remaining portion of the water hook-up charge: $5,393.00/unit b) A portion of the sanitary sewer hook-up charge: $1,611.00/unit LANDSCAPING AND TREE PRESERVATION The applicant for the Comer Addition development did not submit tree canopy coverage and preservation calculations. No tree removal is shown for Lot 1, but in the event that the existing house is torn down and rebuilt, the existing ash tree shown on the survey closest to the home will need to be removed. Staff estimated the canopy coverage calculations as follows: Total upland area (excluding wetlands) 46,279 SF Baseline canopy coverage 54% or 25,047 SF Minimum canopy coverage required 35% or 16,197 SF Proposed tree preservation 33% or 15,246 SF The developer does not meet minimum canopy coverage for the site; therefore the applicant must bring the canopy coverage on site up to the 35% minimum. The difference between the required coverage and the remaining coverage is multiplied by 1.2 for total area to be replaced. One tree is valued at 1,089 SF. Minimum required 16,197 Less canopy preserved 15,246 Minimum canopy coverage to be replaced 951 SF Multiplied by 1.2 1,141 Divided by 1089 = Total number of trees to be planted: 1 tree One tree will be required to be planted in the front yard of Lot 2, when built. Any trees removed in excess of what is shown on the grading plan dated 12/5/18 will be required to be replaced at a ratio of 2:1 diameter inches. Additionally, a birch and maple on Lot 1 are not shown on the tree inventory, but are larger than the 10” dbh minimum for the inventory. They will be preserved on Lot 1. The development is not required to install any buffer yard plantings. 3800 Red Cedar Point Road February 5, 2019 Page 12 PARKS & RECREATION The property has access to the Minnewashta Parkway pedestrian trail and to Roundhouse Neighborhood Park. The applicant will need to pay park dedication fees for one lot at the rate in force at the time of final plat approval. At today’s rate, that would be a payment of a $5,800. This fee will be deposited in the city’s Park and Trail Dedication Fund for utilization on future park and trail improvements. The dedication fees are used to improve the city’s park system. For example, Roundhouse Park recently had four pickleball courts and one tennis court installed utilizing $336,000 in park dedication funds. COMPLIANCE TABLE Area (sq. ft.) Width (ft.) Depth (ft.)

All permits and approvals must be received from other regulatory agencies prior to issuing permits. 2. The applicant shall pay the SWMP fee for 1.06 acres at the rate in force at the time of final plat approval. Should the Planning Commission recommend denial of the City Council deny the preliminary and final plat and variance request, it is recommended that the Planning Commission City Council adopt the following motion: “The Chanhassen Planning Commission Recommends that the Chanhassen City Council denies the preliminary and final plat for a two-lot subdivision with a lot frontage variance for Lot 1, Block 1, Comer Addition, and adopts the attached Findings of Facts and decision.

The Planning Commission conducted a public hearing on the proposed development which was preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and recommended approval. On February 25, 2019, the Chanhassen City Council met at its regularly scheduled meeting to consider the application of a Preliminary and Final Plat to subdivide a 1.062 acre lot into two (2) single-family lots with a variance, Comer Addition and now makes the following: FINDINGS OF FACT 1. The proposed subdivision is consistent with the zoning ordinance; Finding: The subdivision meets all the requirements of the RSF, Residential Single Family District and the zoning ordinance if the lot frontage variance is approved. 2. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan; Finding: The proposed subdivision is consistent with the comprehensive plan and subdivision ordinance. 3. 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; Finding: The proposed site is suitable for development subject to the conditions specified in this report. 4. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; Finding: The proposed subdivision is served by adequate urban infrastructure. 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision will not cause significant environmental damage subject to conditions of approval. The proposed subdivision contains adequate open areas to accommodate house pads. 6. The proposed subdivision will not conflict with easements of record; Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements. 7. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: a. Lack of adequate stormwater drainage. b. Lack of adequate roads. c. Lack of adequate sanitary sewer systems. d. Lack of adequate off-site public improvements or support systems. Finding: The proposed subdivision will have access to public utilities and streets. 8. Variances. – Section 20-58 of the City Code provides the following criteria for the granting of a variance: a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The intent of the zoning code’s minimum lot frontage is to ensure sufficient space for a building pad that can accommodate a house and garage while meeting the district’s 10-foot side yard setbacks. The proposed lot width of 108.85’ is in excess of the district’s 90’ minimum and can easily accommodate the 60-foot by 60-foot building pad required by ordinance. The variance is needed only because the lot width does not front a public street; however, access is provided by an existing private driveway easement. Since both access and minimum lot dimensions are provided, the requested variance is consistent with the general purposes and intent of this Chapter and the comprehensive plan. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties", as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: In order to comply with the minimum lot frontage stipulated in the zoning code, atypical lot configurations or the construction of a private or public street would be required. These configurations would also result in increased impervious surfaces within the shoreland management district. The applicant’s proposed lot dimensions exceed those required by the zoning code and the existing private driveway easement provides reasonable access to Lot 1, Block 1. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The plight of the landowner is the result of the fact that right-of-way for Kirkham Road was dedicated to the city, but the road was never constructed and a portion of it abutting the property was subsequently vacated. During the vacation process, an easement was placed over the vacated portion of the right-of-way to provide access to the house located on the northern half of the parcel. The landowner’s inability to meet the lot frontage requirements stems from the unique circumstances of the property is not the result of the landowner’s actions. e. The variance, if granted, will not alter the essential character of the locality. Finding: The proposed variance would allow for the northern portion of the property to continue to be accessed from Hickory Road via a private driveway easement. Since this is a continuation of the existing conditions within the neighborhood, it will not negatively impact or alter the character of the locality. The proposed lots associated with the variance request both exceed the district’s minimum dimensions and would not be atypical for the area. f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. 10. The planning report, Planning Case 19-02, dated February 5, 2019, prepared by MacKenzie Walters, et al, is incorporated herein.

"Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: The homeowner could subdivided the property by dedicating right-of- way and constructing a public road, upgrading the private driveway to meet private street standards, or by utilizing a flag lot. The inability to create the preferred configuration for the lots is not a practical difficulty. c. That the purpose of the variation is not based upon economic considerations alone.

Box 147 Chanhassen, MN 55317 (952) 227-1100 CHANHASSEN PLANNING COMMISION REGULAR MEETING FEBRUARY 19, 2019 Chairman Aller called the meeting to order at 7:00 p.m. MEMBERS PRESENT: Andrew Aller, Mark Undestad, Steve Weick, Nancy Madsen, and Michael McGonagill MEMBERS ABSENT: John Tietz and Mark Randall STAFF PRESENT: Kate Aanenson, Community Development Director; MacKenzie Walters, Associate Planner; and Erick Henricksen, Project Engineer PUBLIC PRESENT: John Kunitz 6441 Bretton Way Jerry Cone 6320 Minnewashta Woods Drive Tony Fricano 980 Lake Lucy Road Lynn Pelto 6581 Foxtail Court Annette Stock-Lind 8104 Dakota Lane Rodney Colson 6440 Pipewood Colleen Johnson 5015 St. Albans Bay Laurie Susla 7008 Dakota Avenue PUBLIC HEARING: CONSIDER A TWO-LOT SUBDIVISION WITH A VARIANCE FOR REDUCED LOT FRONTAGE AT 3800 RED CEDAR POINT ROAD. Taping of the meeting started at this point in the staff report. Walters: …sewer access currently so from the north up here and the proposed Lot 2 on the south had utilities stubbed in in 1974 off of Red Cedar Point to the south. Sorry I’m having a little trouble changing slides for whatever reason. With regards to right-of-way streets and easements, no right-of-way dedication is being requested. The plan is for Lot 1 to be accessed via the existing driveway easement up through the vacated Kirkham Road onto Hickory. Lot 2 will have driveway access to Red Cedar Point and the applicant is going to dedicate a 5 foot side yard drainage and utility easements and then 10 foot easements along the front yard and they will be dedicating, asking for the designation of the northern lot line here as the front lot for Lot 1, Block 1. This is really slow. Sorry, bear with me a minute. Regarding the proposed variance request they are, they gave us a couple options to show the feasibility of doing the subdivision without a variance. That’s shown as Concept A or Concept B. They’re proposing again having zero feet actually on a strip public street because the front lot line would be where there is not a street. Chanhassen Planning Commission – February 19, 2019 2 The reason for this is the Kirkham Road is not improved. In order to do it without requiring a variance they could install a private street which would involve several thousand feet of impervious surface within the area. They could also dedicate land to the city right-of-way and conduct, construct a public street. They could also use a flag lot configuration which would involve having a 30 foot neck that would service this rear parcel off of Red Cedar Point. All of these would result in an increase in impervious surface within the subdivision and given that the lots exceed the minimum dimensions required and lot area required staff’s preference would be to minimize the amount of impervious surface installed within the shoreland district. Staff has been contacted by several individuals in the neighborhood. Comments have fallen into two categories. One was concern that the subdivision not exceed two lots. Staff’s reassured folks that what’s being proposed is a two lot subdivision and there is no contemplation or potential for more than two lots to come from this. There has also been concern expressed over the subdivision’s potential impact on the area’s stormwater. Mainly staff’s been informed that Hickory is a low point and there’s concern that increased impervious would cause more runoff to be diverted into that area. Staff clarified that under the subdivision ordinance two lot properties are not required to install their own stormwater infrastructure or improvements and that the development would need to meet city and watershed requirements when they pull a building permit. So looking over the proposed subdivision it could go forward without a variance through the use of either a private street or a public street or through a flag lot which would require a variance from the subdivision ordinance but it would likely meet all of those criteria. All of the above mechanisms would require additional impervious surface. Staff as I mentioned believes it’s important to minimize the amount of impervious surface within the shoreland district. Both of the proposed lots are significantly larger than the residential single family district’s minimum lot width, depth and lot area requirements. Lot 1 will have access provided to a public road from the existing driveway easement which is a continuation of the current situation in the neighborhood and the subdivision meets all the requirements of the city code so for all of these reasons staff is recommending approval of the preliminary plat with the variance. I’d be happy to address any questions you have at this time. Aller: Any questions of staff at this point? Commissioner McGonagill. McGonagill: One question I had is mostly my own education on Lot 2 I notice they have a rock driveway going in. Walters: That is conceptual for the construction so they, you know they can put the rock entrance so that they can get the construction vehicles there when building. So they showed that in the grading plan I believe on the plat. McGonagill: Right, I was just wondering were they doing that to avoid an impervious surface or are they thinking about they’ll pave it down the road? Walters: It would be paved after construction. That would only be for like some of the grading activities as part of the construction. Chanhassen Planning Commission – February 19, 2019 3 McGonagill: Okay, thank you sir. Walters: Yep. Aller: Additional questions. Hearing none if the applicant would like to come forward and make a presentation that would be great. If you could state your name and address for the record sir. Rod Colson: Sure Rod Colson with Colson Custom Homes, 6440 Pipewood Curve. Aller: Welcome. Rod Colson: Thank you. Aller: Tell us about your project. Rod Colson: Well it’s a pretty straight forward two lot subdivision. There’s nothing special about it. Aller: There had been some concerns stated about the amount of water runoff and whether or not there’s a storm drainage problem based on the fact that this property would be built or subdivided. Can you address those issues a little bit? Rod Colson: Well I don’t think that it’s going to be creating more of a problem or making any problems that are there worst than already the, Hickory Road is the low point anyway so a lot of the water comes across and then it comes up from the lake when we have high water. Aller: Will the property when you build the property it’s going to have it’s own drainage area or no drainage area? Is it going to have, what’s it going to use to wick water away from your construction? Rod Colson: We’ll be well under the hard cover so it will, the soil’s pervious will absorb the water. There’ll be some runoff but that’s normal. There’s already runoff coming through from the lot to the west up high so. Aller: Additional questions? Okay thank you. Rod Colson: Thank you. Aller: We’ll open the public hearing portion of this item so this is again an opportunity for an individual that’s present to come up and speak either for or against the item. Make a comment. The public hearing is now open. Seeing no one come forward I’ll close the public hearing. And Chanhassen Planning Commission – February 19, 2019 4 entertain comments, concerns, questions, additional questions of staff or a motion. Commissioner Madsen. Madsen: Yeah it looks like a, as presented would be better than the flag lot or some of the other alternatives in trying to reduce the impervious surface and that would be with the recommendation that staff is proposing. Aller: I see a lot of sense. Commissioner Weick. McGonagill: And this will include the new address right? Walters: That is one of the conditions of approval. Weick: I was going to propose a motion. Aller: Please do. Weick: I don’t want to rush anybody but the Chanhassen Planning Commission recommends that the City Council approve the preliminary plat for a two lot subdivision and approve a lot frontage variance for Lot 1, Block 1, Comer Addition as shown in the plans dated December 5, 2018 subject to the conditions of approval and adopting the Findings of Fact and Recommendation. Aller: I have a motion. Do I have a second? McGonagill: Second. Aller: Having a valid motion and a second, any further comments or concerns? I just want to say that I think under our guides we are looking for what will be least impactful and a reasonable use of the property and when we look at the situation here we have an opportunity to create a situation where there’s better stormwater management and reduction of the impervious surface so I think it’s a good plan as well. Any additional comments? Weick moved, McGonagill seconded that the Chanhassen Planning Commission recommends that the City Council approve the preliminary plat for a two-lot subdivision and approves a lot frontage variance for Lot 1, Block 1, Comer Addition, as shown in plans dated December 5, 2018, subject to the conditions of approval, adopts the findings of fact and recommendation: Building: 1.
