The City Council also approved the Amendment to the Lake Susan Hills PUD contract to state the impervious surface coverage of the site cannot exceed 35%. The applicant is requesting final plat approval to replat 21.34 acres into I lot and 1 outlot. This subdivision is consistent with the preliminary plat and staff is recommending approval. Powers Ridge Apartment Homes April 1 0, 2000 Page 10 SUBDIVISION The subdivision request consists of subdividing 21.34 acres into one lot and one outlot. Lot 1 will contain apartment building A, which was approved by the City Council on March 13,2000. Outlot A will be replatted in the future into 3 lots and will contain the remaining three phases of the Power Ridge Development. The subdivision request is a relatively straightforward action. GRADING & DRAINAGE The project will involve grading the entire site to prepare building pads, street and parking lots, and stormwater ponding areas. Temporary stormwater ponds are also proposed to manage site runoff in general accordance with the City's Best Management Practice Handbook (BMPH). As a condition of preliminary plat approval, the berm in the southeasterly part of the site adjacent to Lots 4 and 5, Lake Susan Hills West, was to be extended northwesterly 25 feet. The plans do not reflect this condition of approval. Staffhas directed the applicant's engineer to go back and increase the length of the berm. The final grading and utility construètion plans were returned to the applicant's engineer for additional modifications. The corrected plans should be returned to staff by Monday, April 10, 2000. UTILITIES Municipal sewer and water will be extended from Lake Drive West from the utility stubouts provided. Sewer and water service will be extended through Phase I and temporarily dead ended at the south line of Lot 1. Sanitary sewer and water improvements are proposed to be installed in general accordance with City Standard Specifications and Detail Plates. The developer's engineer will need to provide on-site inspection to a level at which the engineer will be comfortable in certifying to the City that the public improvement portion of the project has been completed in general accordance with the City's plans and specifications. The project involves installation of public improvements. The developer will be required to enter into a PUD Agreement/Development Contract with the City and provide the City with a financial guarantee in the form of a letter of credit or cash escrow to guarantee construction of the public improvements, erosion control measures and site restoration. The construction plans and development agreement are also being considered by the City Council for approval with the final plat approval process. Powers Ridge Apartment Homes April 10, 2000 Page 11 STREETS Phase I of the project will include extending an 8-foot wide bituminous trail along the south side of Lake Drive West and constructing the easterly driveway entrance through the site. No additional street improvements are proposed other than a pedestrian crossing at Lake Drive West. Access to the site during and after construction shall be limited to the access point shown on the plans. The boulevard along Lake Drive West shall be restored with sod. The developer shall be responsible for any/all relocation of street lights, draintile and appurtenances along Lake Drive West impacted by site construction. EROSION CONTROL Construction plans propose erosion control measures adjacent to all disturbed areas. Type I erosion control which is just a silt fence is proposed around the perimeter of the construction limits. Staff recommends that Type III (heavy duty) erosion control fence be installed adjacent to all wetland bodies. A rock construction entrance will be employed off Lake Drive West. SURFACE WATER MANAGEMENT The site overall consists of 21.34 acres of which one acre is wetland, The developer is only final platting 6,6 acres with Phase 1, therefore, the surface water management fees (SWMP) are only applicable to the 6.6 acres (Lot 1). The remaining site will be charged when platted into lots. The developer is providing water quality ponds for the entire site and therefore is receiving credits against the SWMP fees for Phase I. Future platting of Outlot A will not be entitled to any more water quality credits. The developer shall be responsible for a SWMP fee of $3,742.00 with this plat. MISCELLANEOUS Upon review of the construction plans and final plat, the final plat needs to be revised to incorporate drainage and utility easements over the public portion of the sewer and water lines. The utility width shall be a minimum of 20 feet wide over each public utility line depending on the depth of the utility service. In addition, the final plat shall be revised to reflect the current surrounding plat north of Lake Drive West. LANDSCAPING AND TREE REMOVAL Landscaping required for the proposed development is shown in the following table.

The applicant has submitted ground cover plan showing areas of seed or sod. Minimum maintenance areas have been seeded with a ground cover that will not require mowing. These areas are generally sloped and would be difficult to manicure. PARK AND TRAIL DEDICATION FEES As part of the whole Lake SuSan Hills PUD, a significant amount of parkland was dedicated to the city and trails were to be developed by the applicant. Therefore, the PUD contract requires no trail fees and Yo park fees. No parkland will be required with this proposal.
