East Washington Street Water Main
City of Petaluma, California

West Yost provided design and construction support services for 5,000 feet of 18-inch PVC water main to replace three existing 6/8/10-inch cast iron water mains. The project is located on historic East Washington Street and included an investigation of contaminated soils and a trenchless bore and jack crossing under a railroad.

This project included coordinating with Caltrans to obtain design information regarding the relocation of utilities in anticipation of future highway improvements, and to obtain encroachment permits for work within Caltrans right-of-way.
