Planning & Zoning Board April 10, 2002 Page 8 APPROVED MINUTES With respect to grading and drainage, staff stated a grading plan had been submitted and was subject to the review and approval of the City Engineer. A Rice Creek Watershed District (RCWD) Land Development Permit was also required. The house pad on Lot 9, Block 9 should be reoriented to provide a mo re suitable building pa d. The plan does not identify the Normal or High Water Level for wetlands No. 12 and No. 13. Staff noted mitigation sites were proposed to be fenced off after grading was completed to restrict construction traffic. According to the plans, there were no provisions for bringing materials onto the si te or hauling off the site. With respect to utilities, staff stated a preliminary plan had been submitted and was subject to the review and approval of the Ci ty Engineer. Sanitary Sewer was proposed to be expected to the site from its existing lo cation in Sherman Lake Road, north of Birch Street. Water would be provided by connec tion to the existing 16” trunk water main lying adjacent to the property on the south si de of Birch Street. The water main was proposed to be looped back to the system by crossing Birch Street at Pheasant Hills Drive. Staff indicated adequate capacity exis ted in the sanitary sewer system to service the proposed development. In addition, the Black Duck Lift Station, which served the area, was scheduled for replacement in 2003. Staff stated with respect to drainage and utility easements were being proposed five feet in width at adjoining lot lines, and 10 feet in width at adjoin ing street lines and rear lot lines as required. Drainage and Utility easements covering the 100 year High Water Level and those covering underground storm sewe rs were subject to review and approval by the City Engineer. Easements would be provided to access all pond and wetland areas. Specifically, easements should be provided to access Outlot F and cover the emergency overflow on Lots 6, 9 and 10, Block 8. With respect to Parkland dedication, staff st ated the Park Board discussed the proposed subdivision at its February 4, 2002 meeti ng. The Board was recommending 100% cash payment in lieu of parkland dedication. As e xplained in the Public Services Director’s February 5, 2002 memorandum, the proposed development lies outside the planning limits of the Comprehensive Park and Trial System Plan. The Park Board looked at several alternatives and recommended the payment in lieu as the preferred option. Regarding floodplain, staff stated portions of th e site lies within the Floor Plain Zone A. Zone A represented areas of 100-year floor where based floor elevations had not been determined. The City’s Floodplain Manage ment Ordinance required that principal structures be located no lower than one foot above the regulatory flood protection elevation. The City’s subdivision Ordinan ce required that proposed basements be four (4) feet above the water tabl e (normal water level) and tw o (2) feet above the design flood levels of ponding areas. Staff stated the submitted grading plan id entified proposed 100 feet High Water Level elevations. Conformance to the requirements could not be determined for Lots 23 and 27, Block 8 due to lack of documentation on the normal and high water levels of wetlands No. 12 and No. 13. The applicant s hould submit this documentation. All other lots were in conformance.
