As detailed in the May 11, 2020 Council staff report and Resolution No. 22-44 approving PUD Development Stage Plan Amendment #1 to the site plan and grading & drainage plan, the clubhouse was omitted in order to enlarge to the stormwater pond to provide more capacity. 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. 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 that 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 is being reviewed by the City Engineer and Building Official. as a site amenity. The clubhouse has been omitted from the project.
