The applicants are requesting final plat approval for the 2"a Addition creating 28 single family lots and 3 outlots. Outlot A is thc northern wetland, Outlot B is thc southwest comer of the development to be platted in the funn'e and Ou'dot C is the trail. The group home is currently being removed from thc site and thus allowing for the 2"a Addition to be completed. The city is taking a small portion of uphmd ~. There will be no park or trail fees with this addition. All lots meet the stan~ of thc R4 zoning district. GradiI~ The existing site is bordered by wetlands along thc west and north property lines. Thc new West 78th Street rtms along the southern property line. Thc site is also outlined by groves of significant trees, along with a section of trees that extends toward the center of the site from the west. In addition, there are four existing buildings on the ~ which will have to be razed prior to any grading operations. The existing well and septic systems must be capped and/or removed in compliance with state health cedes. In an effort to save as many of thc significant trees on the site as possible, the applicant is proposing to custom grade 16 lots in the west-central and northwest portion of the site. Staff agrees that this is the most environmentally sensitive The City of Chanhassen · A growing community with clean lakes, quality schools, a charming downtown, ~rivlng businesses, winding trails, and beautiful parks. A Onn~ place to live, ~rk, and play. 5 6 Ridge Ct mn Ridge Ln ~mn Ridge Way Harvest W Autumn Ri, Vasserman Ridge 2aa Addition April 9, 2003 Page 2 way to develop these lots. Detailed grading, drainage, tree removal and erosion control plans will be required for each lot at the time of building permit application for City review and approval. In addition, as-built surveys will be required on each lot prior to occupancy. Significant site grading will be needed to prepare the site for home construction. The developer intends to grade the remainder of the site with this phase. As part of the grading operations, large berms (10'-20' tall) are proposed along the south property line of the site to buffer the development from West 78th Street and associated noise. This is necessary due to the lack of noise abatement with the Highway 5 project. West 78th Sueet is currently a MnDOT road and, as such, MnDOT will have to review and approve the grading plan. If importing or exporting material for development of the site is necess~, the applicant will be required to supply the City with detailed haul routes and traffic control plans. The north half of the existing.site drains to the large ag/urban wetland along the northern property line. The westerly most portion of the site drains to the existing natural wetland along the west property line. The remaining southerly portion of the property drains to West 78th Street and eventually a MnDOT storm pond. The proposed grading plan has been designed to match the existing drainage patterns fairly well. The north and eastern portions of the second phase will drain to the existing pond in the southeast comer of the site. This pond was installed with the first addition and was sized to accept the second phase drainage. The pond will treat the water before discharging it to the adjacent wetland. The remainder of the site north of West 78th Street will drain to a proposed pond in the south-cmnmd portion of the site and discharge to the MnDOT storm sewer system. The new pond is required to be designed to National Urban Runoff Program (NURP) standards. The proposed drainage plan is consistent with the City's Surface Water Management Plan (SWMP). While the proposed pond will be graded in with the second phase, the applicant is not proposing to install the entire storm sewer system to the pond with this phase. Rather, the applicant would like to end the storm sewer approximately 440 feet short of the pond. From there the storm sewer would discharge to a temporary swale or ditch which would convey the drainage to the new pond. Because of the large possibility of erosion and maintenance issues with a swale, staff is recommending that the temporary swale be deleted. Instead, staff is recommending that either a temporary pond be dug at the outfall of the storm sewer or that the complete storm sewer system be installed up to the pond. According to the grading plan, the applicant intends to drain the commercial parcel to the existing MnDOT pond on the south side of West 78th Street. This will require that the pond be enlarged to handle the additional runoff from the commercial site. Without MnDOT approval on the enlargement of the existing pond, the applicant will be required to provide a separate, on-site pond. Vasserman Ridge 2n~ Addition April 9, 2003 Page 3 The applicant has submitted drainage calculations for the site but some revisions are needed. Staff will work with the engineer to correct the calculations. Drainage and utility easements will need to be dedicated on the final plat over the public storm drainage system including ponds, drainage swales, emergency overflows, access mutes for maintenance, and wetlands up to the 100-year flood level. The minimum easement width shall be 20 feet wide. Emergency overflows from all stormwater ponds have been shown on the construction plans. Erosion Control Erosion control measures and site restoration shall be developed in accordance with the City's Best Management Practice Handbook (BMPI-1). Staff recommends that the City's Type III erosion control fence, which is a heavy-duty silt fence, be used for the ama adjacent to the existing wetlands on the north and west grading limits of the site. Type H silt fence shall be used in all other areas. A minimum 75-foot rock construction entrance must be shown al the entrance of Ridgeview Way off of W. 78t~ Street. In addition, wood-fiber blankets will be required on the steep slopes of the proposed berms, the enlarged portion of the MnDOT pond, and off the west side of the Ridgeview Point cul-de-sac. Utilities The plans propose on connecting to the existing sanitary sewer and water mains which were installed with the first phase, and extending them to serve the second phase. The applicant is proposing to extend the sewer and water outside of the platted right-of-way in two locations. In each case, temporary public drainage and utility easements will be required for the utility lines that are outside of the platted fight-of-way. As part of the preliminary plat approval for this develo~t, it was determined that 30 additional sanitary sewer and water lateral connection charges would be required. These connection charges were based on the additional number of units that will be platted versus the amount of units that the property had been assessed for. The applicant is now proposing to final plat 16.1 acres or 23% of the ultimate site development of 68.8 acres. Using thig same area percentage, 23% of the 30 additional units or seven additional connection charges will be required to be paid upon final plat approval of the second addition. Based on the current 2003 rate, the total amount due payable to the City for the seven additional connections charges would be $31,591 (7 @ $4,513). In addition, each newly created lot will be subject to City sanitary sewer and water hook up charges al the time of building permit issuance. The 2003 mink utility hook up charges are $1,440 per unit for sanitary sewer and $1,876 per unit for water. Hook-up charges are for core utility system infrasmmmm, i.e. wells, lift stations, water towers, etc. Connection fees are in lieu of assessments which were absorbed by the City instead of being levied at the time of construction. In this case, more units are proposed to be consmmted than originally anticipated. Utility improvements are required to be consmLeted in accordance with the City's latest edition of Standard Specifications and Detail Plates. Detailed construction plans and specifications have Vasserman Ridge 2nd Addition April 9, 2003 Page 4 been submitted for staff review. The applicant is also 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 impxovements and the conditions of final plat approval. Permits from the appropriate regulatory agencies will be required prior to construction, including but not limited to MPC& Department of Health, lVInDOT, Watershed District, etc. Streets Overall, the proposed street layout appears to work well. The entire street system is shown within a 60-foot wide public right-of-way with 31-foot wide streets in accordance with City design criteria. Sidewalk is proposed on one side of all the through streets. This sidewalk will connect with the existing sidewalk from the first phase and with the proposed trail along the north side of the property. The proposed cul-de.sac (Ridgeview Point) contains a landscaped "island" in the center. This island will be encircled by curb and gutter and maintained by the development's homeowners association. The City has allowed similar islands in the past and staff would recommend only that the configuration be acceptable to the City's Fire Marshal. An encroachment agreement will be required for the island within the fight-of-way. Temporary cul-de-sac tumarounds have been proposed at the terminus of Vasserman Trail and Ridgeview Way. Each of these tumarounds is located outside of the platted right-of-way. As with the utility lines, temporary easements will be required for the portion of the public street that is outside of the platted right-of-way. Landseapin~ The entire landscaping plan was approved with the first Addition. Surface Water Management Fees Water Quality Fees Because of the impervious surface associated with this development, the wamr quality fees for this proposed development are based on single-family residential development rates of $949/acre. Based on the proposed developed area of approxirr~tely 16.2 acres for Phase IL the water quality fees associated with this project are $15,374. Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an av~age citywide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels, and storm water ponding areas for runoff storage. Single- family residential developments have a connection charge of $2348 per developable acre. This results in a water quantity fee of approximately $38,038 for the proposed development. Vassennan Ridge 2nd Addition April 9, 2003 Page 5 At this time, the total SWMP fee for Phase IL due payable to the City at the time of final plat recording, is $53,411.

The assessments for the BC-7/BC-8 project were based on the existing zoning for the site yielding a developed total of 68 units. Since the applicant is now proposing more units (84 + 3 units for the commercial lot) than what the property has been assessed for, the additional 19 units (87 - 68 = 19) will be charged a sanitary sewer lateral connection charge. The assessments for the Highway 5 project, based on existing zoning, yielded a developed total of 76 units. As above, since more units are now being proposed than what was assessed for (87 vs. 76), the additional 11 units will be charged a watermain lateral connection charge. The current 2002 lateral connection charge for sanitary or water is $4,335 per unit. Based on the current rote, the total amount due payable to the City for the additional 30 units would be $130,050 (30 @ $4,335). In addition, each newly created lot will be subject to City sanitary sewer and water hook-up charges are $1,383 per unit for sanitary sewer and $1,802 per unit for water. Hook-up charges are for core utility system infrastructure, i.e. wells, lift stations, water towers, etc. Connection fees are in lieu of assessments which were absorbed by the City instead of being levied at the time of construction. In this case, more units are proposed to be constructed than originally anticipated. · This condition should be revised as follows: As part of the preliminary plat approval for this development, it was determined that 30 additional sanitary sewer and water lateral connection charges would be required. These connection charges were based on the additional number of units that wig be platted venus the mount of units that the property had been assessed for. The applicant is now proposing to final plat 16.1 acres or 23% of the ultimate site development of 68.8 acres. Using this same area percentage, 23% of the 30 additional units or seven additional connection charges will be required to be paid upon final plat approval of the second addition. Based on the current 2003 ram, the total amount due payable to the City for the seven additional connections charges would be $31,591 (7 @ $4,513). In addition, each newly created lot will be subject to City sanitary sewer and water hook up charges at the time of building permit issuance. The 2003 trunk utility hook up charges are $1,440 per unit for sanitary sewer and $1,876 per unit for water.
