IMPACT AND MITIGATION ANALYSIS. Prepare an impact analysis at defined points of interest (POI) where water leaves project ROW to determine increases in peak flow rates for the 100-year storm including: existing and proposed peak flow rates, mitigation analysis, conceptual detention basin layouts, design of control structures, routing of storm hydrographs through basins, calculate the volume of fill to be placed in the 100-year floodplain, and recommend locations for compensatory storage.
IMPACT AND MITIGATION ANALYSIS. 1. Provide documentation of all adverse impacts resulting from the proposed facility in the proposed condition. Provide a comparison of existing vs proposed condition at each outfall from the project area.
