Yolo Force Main Design
Sacramento Regional County Sanitation District, California

West Yost managed the design of the Yolo Force Main, which is one of eight projects in the Lower Northwest Interceptor Sewer system. The Yolo Force Main project included approximately 25,000 feet of dual 66-inch diameter force mains and microtunneling of twin 84-inch crossings under Babel Slough.

West Yost’s primary responsibilities included project management and coordination, preparing plan and profile drawings, potholing, utility coordination, preparation of environmental condition drawings, and construction-period services. The project required permits and coordination with numerous regulatory agencies including: Yolo Shortline Railroad, Regional Water Quality Control Board, Bureau of Reclamation, two local reclamation districts, U.S. Army Corps of Engineers, California Department of Fish and Wildlife, and U.S. Fish and Wildlife.
