Title

San Joaquin Field Division Operations and Maintenance Center Drainage Culvert Replacement Project

Description

The proposed Project would include replacement of the existing arch corrugated metal pipe culvert with a new concrete box culvert, improvements to the upstream and downstream flow channels, and improvements to the connection to an existing drainage swale. The Project proposes a new pre-cast reinforced concrete box culvert with cast-in-place reinforced concrete headwall structures at each end of the culvert. The headwall structures would consist of one headwall, two wing walls, a foundation slab, and a cutoff wall. The Project would also include improvements within the upstream flow channel, southeast of the existing box culvert, and within the downstream flow channel, northwest of the existing box culvert. Improvements to the upstream flow channel and downstream flow channel would consist of trapezoidal-shaped concrete liners. Additional rock slope protection would be placed to connect an existing drainage swale from the SJFD O&M Center parking lot to the downstream flow channel. An existing gravel parking area located in the southeast portion of the SJFD O&M Center site would be used during construction as a staging area for materials and parking by construction personnel.
