Planning & Zoning Board July 10, 2002 Page 16 APPROVED MINUTES main was proposed to be looped back to the system by crossing Birch Street at Pheasant Hills Drive. Adequate capacity exists in the sanitary sewer system to service the proposed development. In addition, the Black Duck Lift Station, which services the area, was scheduled for replacement in 2003. Drainage and Utility Easements. Drainage and Utility easements were proposed being five feet in width and adjoining lot lines, and 10 feet in width a nd adjoining street lines and rear lot lines as required. Drainage a nd Utility easements covering the 100-year High Water Level and those covering underground st orm sewers are subject to review and approval by the City Engineer. Easement s should be provided to access all pond and wetland areas. Specifically, an easement s hould be provided for access to Outlot F and covering the emergency pond overflow on Lot 6, Block 8. Parkland Dedication. The Park Board discus sed the proposed subdivi sion at its February 4, 2002 meeting. The board was recommending 100% cash payment in lieu of parkland dedication. As explained in the Public Services Director's February 5, 2002 memo the proposed development lies outside the planni ng limits of the Comprehensive Park and Trail System Plan. The Park Board looked at several alternatives and recommended the payment in lieu as the preferred option. Floodplain. Portions of the site lie with a Fl ood Plain Zone A. Zone A represents areas of 100-year flood where base flood elevations have not been determined. The City’s Floodplain Management Ordinance required that all principal structures be located no lower than one foot above the re gulatory flood prot ection elevation. The submitted grading plan identifies propos ed 100-year High Water Level elevations. The Rice Creek Watershed District’s 1998 Ca libration Study identifi es the regulatory flood elevation for this area as 887.6. As cu rrently proposed, all lo t pads were located entirely above this elevati on and all first floor eleva tions satisfy the flood plain requirements. The proposal was subject to the review and ap proval of the City Engineer and Rice Creek Watershed District. If the proposed subdi vision was approved the Developer would be required to make application to FEMA fo r a Letter of Map Amendment (LOMA) or Letter of Map Revision (LOMR) to revise th e existing Flood Plain maps consistent with the proposed grading. Wetlands. The project site contains 19.39 acr es of wetland. 2.06 acres of wetland were proposed to be impacted by the site devel opment. The wetland mitigation would take place on-site, by creating two new wetlands and three water quality ponds, which would have a total area of 2.51 acres and 3.27 acres, respectivel y. A portion (.20 acres) of one of the existing wetland areas woul d be converted from Type 2 wet meadow to a Type 3 shallow marsh wetland to help facilitate site drainage. The developer was proposing to install signs , delineating the wetland edge, at property corners or where the wetland edge changes dr astically within a lot. Approximately 35 to
