Storm Drain Master Plan
City of Napa

West Yost developed the first storm drain master plan for the City. The master plan included: the development of updated planning and design criteria for the development standards, preparation of hydrologic and hydraulic evaluations of existing drain facilities, evaluations of documented problem areas, preparation of cost estimates, development of recommended capital improvements, completion of a financial plan and preparation of the initial environmental study on the master plan recommendations.

West Yost also worked with City staff to develop the flood mitigation program and funding applications to eliminate flooding of existing properties after the US Army Corps of Engineers Napa River Flood Control Project is completed.

Recently, the City selected West Yost to review previously prepared technical studies and schematic-level designs of two technically feasible design alternatives to handle overland drainage in the Soscol Gateway area.
