LEVEL OF CITY DISCRETION IN DECISION-MAKING: 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. 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 Ordinance 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.

The property is zoned RSF, Single Family Residential District. The site is located at the southwest intersection of Lake Lucy Road and Powers Boulevard, and contains a single family home and a detached garage. Access to the site is proposed off of Powers Boulevard and Lake Lucy Road. Burlwood Addition December 8, 2003 Page 8 Lake Lucy Road All lots meet the minimum lot area, width and depth requirements of the zoning ordinance with an average lot area of 21,323 square feet. Each parcel contains a 60' x 60' house pad. Ix)ts 1, 2, 3, and 4, Block ! are proposed to be served via a private street which will require a variance. The proposed right-of-way is 50 feet wide. The ordinance requires 60 feet. The existing fight-of-way located on the Golden Glow Subdivision, is 50 feet wide. This fight-of-way will be in keeping with the existing right-of-way. Outlots A and B are being created to be incorporated into the Christensen property. When the Christensen's are ready to subdivide their property, these outlots will serve as street frontages. A wetland alteration permit was approved with the preliminary plat. it will result in filling 5,963 square feet of wetland and replacing it off site. The right-of-way for the entire cul-de-sac extending into the Golden Glow Acres has been dedicated with the final plat. Staff is recommending approval of the subdivision with variances with conditions outlined in the staff report. Burlwood Addition December 8, 2003 Page 9 PRELIMINARY PLAT The applicant is proposing to subdivide a 5.17 acre site into 7 single family lots and two outlots. The density of the proposed subdivision is 1.3 units per acre gross and 2.0 units per acre net. All lots exceed the minimum 15,000 square feet of area, with an average lot size of 21,323 square feet. All proposed lots meet the minimum width, and depth requirements of the Zoning Ordinance. A wetland occupies the northerly portion of the site and is proposed to be filled and replaced off site. Lots 1, 2, 3, and 4, Block 1, are proposed to be served via a private street. This layout is in keeping with a previous council recommendation. Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent with the Zoning Ordinance. WETLANDS Existing Wetlands One ag-urban wetland exists in the northern portion of the property. GME Consultants, Inc. delineated the wetland in May 2003. The wetland is dominated by reed canary grass. The applicant is proposing to fill the wetland and mitigate it off-site through the purchase of wetland credits from a wetland bank. The total proposed impact to the wetland is 5,963 square feet (0.14 acres). Because the existing wetland is of low quality and future property owners would likely impact the entire wetland if the wetland was preserved during the subdivision process, staff is recommending sequencing flexibility. This will allow the applicant to fill the wetland and replace it with a wetland of greater function and value off-site through the state wetland bank. Wetland Replacement Wetland replacement must occur in a manner consistent with the Minnesota Wetland Conservation Act (MR 8420). The City Council approved a wetland replacement plan on October 27, 2003. GRADING~ DRAINAGE AND EROSION CONTROL GRADING/DRAINAGE/EROSION CONTROL · The grading plan needs to be revised along the east side of Lot 6, Block 1 to avoid trapping stormwater against the housepad. · The basement elevations of Lots 1 through 4, Block I must be a minimum of three feet above the HWL of the proposed pond. Burlwood Addition December 8, 2003 Page 10 · The proposed storm sewer at the south end of the cul-de-sac must be located five-feet from the existing sanitary line to avoid impacting the existing tree line. Since the preliminary plat approval, the applicant has revised the drainage plan as follows: a storm sewer outlet from the proposed northerly pond has been added which runs west along Lake Lucy Road to an existing public storm sewer system, the underground detention system that was previously proposed has been deleted, and a storm sewer line has been added to handle the stormwater from the south part of the site and the new cul-de-sac. There is a small area at the south end of the site which drains offsite but does not receive any water quality treatment. In accordance with City SWMP requirements, the applicant is required to treat this area to meet water quality standards prior to discharging offsite. · The existing storm line that goes through Lot 1, Block 2 must be replaced and connected with the proposed street storm sewer. · A minimum 20-foot wide public drainage and utility easement is required over the existing ditch/drainage way on the Martinka property. Erosion control measures and site restoration shall be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that a rock construction entrance be shown on the plans in accordance with City Detail Plate No. 5301. UTILITIES · According to City as-built plans, all of the proposed lots have both sewer and water stubs except Lot 6, Block 1. The proposed watermain must be extended to the south with the new cul-de-sac and connected with the existing watermain in the Golden Glow development for looping purposes. · Sanitary and water services shall be extended to the west property line for future development of the neighboring parcels. The underlying parcel has been previously assessed for five utility units and those assessments have been paid. Since the applicant is now proposing more units than what was previously assessed, the one additional unit will be charged a watermain and sanitary sewer lateral connection charge at the time of building permit issuance. The current 2003 connection charge for water and sewer is $4,513 each. Sanitary sewer and water hookup charges along with the Met Council's SAC fee will be due on all of the lots at the time of Burlwood Addition December 8, 2003 Page 11 building permit issuance. All of these charges are based on the number of SAC units assigned by the Met Council. The current 2003 sanitary hookup charge is $1,440/unit, the water hookup charge is $1,876/unit and the SAC fee is $1,275/unit. Public utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant will also be required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. Permits from the appropriate regulatory agencies must be obtained, including but not limited to the MPCA, Department of Health, Watershed District, Carver County, etc. STREETS The applicant's street layout follows a previous Council approved layout for this property and the street connection with Golden Glow Court to the south. The applicant is proposing to build a public street on his property and to complete a cul-de-sac (Golden Glow Ct.) to the south of his property. The applicant has a signed agreement with the adjacent land owners to dedicate the necessary right-of-way to complete the street. Upon completion of the full street and cul-de-sac, the existing private street, which serves Lots 3 and 4 of Golden Glow and the Rohman/Infanger parcels, would access onto the new public street and not Powers Boulevard. Lot 1 of Golden Glow would, however, continue to access Powers Boulevard through its existing driveway. The developer will be required to pave the portion of the existing neighbors' driveways that are within the subject property as per City ordinance. A private driveway easement will also be required for the shared portion of the driveway. In addition, any shared portion of the driveway must be constructed to a 7-ton design. The developer will be required to provide inspection reports verifying this. PARKS This property lies within the neighborhood park service areas of both Curry Farms Park and Carver Beach Park. TRAILS Two segments of the City's Comprehensive Trail Plan are located near this property. The first is an on-street trail located along both the eastbound and westbound lanes of Lake Lucy Road. The second is an off-street 8 ft. wide bituminous trail located on the east side of Powers Boulevard. Burlwood Addition December 8, 2003 Page 12 This is across the street from the subject plat. The best crossing location for pedestrians is at the intersection of Powers Boulevard and Lake Lucy Lane. With these public services in place, the Park and Recreation Director is not recommending any additional public park or trail services be constructed as a part of this subdivision. In lieu of any public improvements, a park dedication charge of $19,200 will be applicable at the time of platting. TREE PRESERVATION/LANDSCAPING Canopy coverage and preservation calculations have been submitted for the Burlwood development. They are as follows: Total upland area (excluding wetlands) Baseline canopy coverage Minimum canopy coverage allowed Proposed tree preservation 5.27 ac. or 229,583 SF 35 % or 79,465 SF 30% or 68,875 SF $15% or 22,958 SF The developer does not meet minimum canopy coverage allowed, therefore the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage (68,875 -22,958) Multiplier Total replacement Total number of trees to be planted 45,917 SF 1.2 55,100 SF 51 trees (55,100+ 1089) The total number of trees required for the development is 51. The developer has proposed a total of 12 trees. An additional 39 trees must be added to the landscape plan. All replacements must meet minimum size requirements. No more than one-third of the trees may be from any one species. The canopy coverage and replacement calculations submitted by the applicant differ from those presented by staff. According to the submitted calculations, the canopy coverage saved is 30%. Staff does not agree with their calculations for two important reasons: 1) some of the trees listed and counted as preserved are not on the applicant's property; 2) many of the trees listed as preserved are actually within the grading limits such as in the areas proposed as berm or pond. Staff does not accept the claim of tree preservation for any trees that are not protected by fencing and outside of grading limits. Therefore, tree preservation on site has been calculated at 15% which includes trees located on Lot 1, Block 2, the west side of the property behind a silt fence located at the grading limits, and the 12 evergreens scheduled for transplanting. Burlwood Addition December 8, 2003 Page 13 The subdivision is also required to have buffer yard plantings along Powers Blvd. and Lake Lucy Road. Requirements are as follows: Location Required Proposed Powers Blvd. - buffer 10 overstory trees 0 overstory yard B - 20' width 15 understory trees 12 understory 500' length 25 shrubs 0 shrubs Lake Lucy Road 4 overstory trees 0 overstory Buffer yard B - 15' 8 understory trees 3 understory width 12 shrubs 0 shrubs The developer has proposed a 4' berm along Powers Blvd. on top of which would be placed transplanted evergreens. The buffer yard area is only 20 feet wide and a 4' berm would require at least 24 feet in width in order to meet the city's 3:1 slope standard. The developer should reduce the berm to 3' in height or install a fence instead.

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. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; Finding: The proposed site is suitable for development subject to the conditions specified in this report 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. 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. 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. Burlwood Addition December 8, 2003 Page 15 The proposed subdivision is not premature. A subdivision is premature if any of the following exists: Lack of adequate storm water drainage. Lack of adequate roads. Lack of adequate sanitary sewer systems. Lack of adequate off-site public improvements or support systems. Finding: The proposed subdivision will have access to public utilities and streets. VARIANCE Section 18-57. Streets. (r) Private streets serving up to four (4) lots may be permitted in the A2, RR, RSF and R4 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 construct 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. (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 protected areas. Staff is recommending approval of the private street based upon the analysis provided in the background section of the report. VARIANCE FINDINGS Sec. 18-22. Variances. The city council may grant a variance from the regulations contained in this chapter as part of the plat approval process following a finding that all of the following conditions exist: (1) (2) (3) The hardship is not a mere inconvenience; The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land; The condition or conditions upon which the request is based are unique and not generally applicable to other property; Burlwood Addition December 8, 2003 Page 16 (4) The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance and comprehensive plan. Finding: Based upon the analysis within the background section of the report, it is possible to serve the site through a public street; however, by doing so, site grading and the dependence on other property owners increases. The applicant's request is fairly reasonable. As to the 50 foot fight-of-way width, it is in keeping with the existing fight- of-way for Golden Glow Court. Based upon these findings, staff is recommending approval of this variance. RECOMMENDATION Staff recommends the City Council adopt the following motions: FINAL PLAT "The City Council approves the final plat for Subdivision #03-12 for Burlwood Addition for 7 lots and two outlots with variances to allow a private street and a 50 foot right-of-way as shown on the plans received October 20, 2003, subject to the following conditions: 1.
