Additionally, the reduction in street width coupled with a curvilinear design of the subdivision's streets may reduce visibility of on -street pedestrian movements. Sidewalks along Street A and Street B may be necessary to alleviate this concern. He noted the Environmental Board recommended reducing the street width. The Planning & Zoning Board recommended that the street width be constructed to the City standard 32 -foot width. Community Development Director Grochala stated the City Engineer has completed review of the grading and drainage plan. A Rice Creek Watershed District (RCWD) Land Development Permit is also required. The City's Local Water Management Plan calls for the minimum floor elevation, including basement to be 4 feet above the groundwater, 4 feet above the normal water level, or 2 feet above the 100 year flood elevation, whichever is greatest. The plan appears to satisfy these requirements based on the proposed normal and high water levels. The developer is currently monitoring existing groundwater elevations at approximately ten sites for verification. Final adjustments will be made with the final grading plans. He notee mitigation sites are proposed to be fenced off after grading is completed to restrict construction If soils are to be brought to the site they must be consistent with existing soil types. Community Development Director Grochala stated the Ci gi ger has completed review of the utility plans.

Community Development Direc r Grochala advised that the Park Board discussed the proposed subdivision at its February 4, 2002 meeting. The Board is recommending 100% cash payment in lieu of parkland dedication, about $165,000. The proposed development lies outside the planning 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. Community Development Director Grochala pointed out that portions of the site lie within a Flood 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 requires that all principal structures be located no lower than one foot above the regulatory flood protection elevation. The submitted grading plan identifies proposed 100 -year high water level elevations. The Rice Creek Watershed District's 1998 Calibration Study identifies the regulatory flood elevation for this area as 887.6. As currently proposed, all lot pads are located entirely above this elevation and all first floor elevations
