CWE is assisting the City of Visalia with its Stormwater Master Plan update to meet the City’s General Plan policies.  The update will minimize storm water runoff and volumes, control water pollution, and maximize groundwater recharge covering approximately 38 square miles within and near the City.  Tasks include: review of existing data and collection of new data; model development and analysis using Environmental Protection Agency Stormwater Management Modeling (EPA SWMM); waterways modeling and analysis using Hydrologic Engineering Center River Analysis System (HEC-RAS); evaluation of retention basins, pumps, and discharge pipe modeling and analysis, preparation of a master plan based on the results; and evaluation of floodplains and the Community Rating System.
