Document Description
Caltrans proposes to make repairs to a leaking pipe at the Boonville Maintenance Station in Mendocino County, near post mile 28.09. The purpose of this emergency project is to restore the maintenance station to a safe and operational condition. The project is needed as an underground pipe is leaking. The leaky pipe is located near the main office building and supplies water to the maintenance facilities, Caltrans special crew facilities, and other buildings accessed by staff and used to house equipment in the yard. Maintenance forces have made a temporary fix that only slows the leak and are unable stop the leak. The pipes are in extremely poor condition and represent a threat to the facility. The leaking pipe is wasting water, pumping pavement (water moving up through the asphalt causing undermining of the base and subgrade materials and premature asphalt failure), and has the potential to contaminate the water supply to the maintenance station. There may also be potential risks to accessing water by fire-fighting personnel. The existing damaged pipe has exceeded its service life and is substandard compared to today’s standards. The proposed solution is to repair/replace the existing pipe. The new water line will be installed based on current standards and any lateral connections will be repaired as required.
