Project Info
- Title
- Pulgas G20 Shaft Site Drainage Improvement and Erosion Repair Project
- Description
- The Project includes installing a new 95 foot long box culvert south of the PG&E substation, joining the existing unnamed intermittent stream channel at or very near the current inlet and outlet, grouting and abandoning in place the existing culvert to prevent further subsidence, surface contouring the immediate surrounding area to direct storm water run-off away from the substation and installing an eight-inch diameter corrugated metal pipe (CMP) from the substation to the proposed culvert outlet. The culvert installation will also involve the construction of reinforced concrete structures at the inlet and outlet and the placement of approximately 57 CY of cement grout to abandon the existing CMP culvert.
