The goal of the South Canal Improvement Project was to significantly increase the District´s ability to fully utilize their connection to the California Aqueduct. Improvements included raising the canal lining up to 6-feet over nine miles; modifying canal side facilities including pump stations, turnouts, drain inlets, bridges and pipe crossings; construction of four reverse flow pump stations/check structures; adding an 84-inch road crossing; increasing storage and regulation capacity at the Spillway Basin; and increasing SCADA capability of the District.
Provost & Pritchard prepared a feasibility study, using HEC-RAS hydraulic model, which analyzed 15 alternatives for increasing the capacity in both the reverse and forward flow directions. To meet operational needs, an accelerated schedule was met. Provost & Pritchard provided services consisting of: completing documentation in order to meet California Environmental Quality Act (CEQA) requirements; topographic, right of way, and construction surveying services; land acquisition assistance; design engineering; preparation of plans, specifications, and cost estimates; and construction administration and review services.
