18 Pond Size Comparison Original Pond 3P Enlarged Pond 3P Surface Area 0.56 acres 0.82 acres Volume 2.810 acre ft 3.869 acre ft RCWD issued an amended Conditional Approval Pending Receipt of Changes (CAPROC) on March 13, 2020 October 26, 2020. The District Engineer finds the revised grading and stormwater management plans compliant with RCWD rules. The City’s stormwater management ordinance requires 4 ft of separation between low floor freeboard and groundwater. In order to minimize the site being built up to meet this requirement, this separation distance may be reduced upon submittal of a geotechnical report and design by a licensed engineer. This report shall define ground water level elevations for the senior living complex and include plans demonstrating potential ground water inflow will be adequately mitigated. Said mitigation shall be approved by the City Engineer. As supported by Resolution No. 19-42, Braun Intertec submitted a Sub-Slab Drainage System Design. The drainage system will mitigate potential future groundwater infiltration into the lowest level of the senior building. The plan has been reviewed by the City Engineer and Building Official. The clubhouse has been strategically located adjacent to the landscaped stormwater pond as a site amenity. The clubhouse has been omitted from the project.
