Document Description
The project will replace a damaged 60-inch diameter corrugated metal pipe (CMP) storm drain beneath the sidewalk, curb, and gutter along Port Chicago Highway with reinforced concrete pipe (RCP) and repair sinkholes that resulted from the pipe failing. The project is needed to properly convey surface water drainage and natural flows from Shore Acres Creek through the storm drain CMP and return the sidewalk, curb, and gutter to satisfactory condition. Work may also include temporary trench shoring and protection, dewatering, traffic paint restriping, and installation of American with Disabilities Act-compliant curb ramps at the Port Chicago Highway and Skipper Road intersection. Utility relocations, temporary traffic control, and tree/vegetation trimming and removal may be necessary. Real property transactions, including temporary construction easements, may be necessary in support of the project. Regulatory permits for impacts to the piped creek will be obtained before construction. Construction best management practices will be implemented for water pollution control such as storm drain inlet protection. Construction is anticipated to begin in 2026 and last approximately 30 days. Emergency vehicles will have access at all times.
