Homeacres Drainage Improvements
Vallejo Sanitation & Flood Control District

West Yost prepared the design of Phase 1 of the Homeacres Drainage Improvements. These projects included design of 18-inch to 30-inch storm drains through areas congested with other existing underground utilities, a 48-inch storm drain, and a tailwall and velocity/energy dissipater section of riprap. The project included design of an earth berm 3 feet high and a headwall/drain inlet and curb and gutter at several locations.

West Yost also prepared an initial study /mitigated negative declaration for the environmental review of the projects, presented at public meeting with neighborhood residents, and coordinated the projects with several key private property owners. A US Army Corps of Engineers-Section 404 permit application, a California Department of Fish and Wildlife streambed alteration agreement application, a Regional Water Quality Control Board water quality certification application, and a Caltrans encroachment permit application were also prepared by staff. West Yost provided coordination with these agencies and all required permits were obtained.
