Placentia Canal Drainage Improvements

Upgrade the existing two 72” RCP culverts under Sunset Blvd to two 10x6’ box culverts. The length of the proposed double box culvert is 64 linear feet. The precast box culvert must utilize a “water tight” ASTM C1677 joint in lieu of the “soil tight” ASTM C990 joint that has typically been utilized locally. The double box will be supported on a geotextile and 12 inches of #57 stone. The project will also include cast-in-place wingwalls and aprons. 32 LF of 30 inch RCP will be replaced. Both the 30” RCP and a 36” CMP will discharge through the wingwalls. Approx. 130 LF of sand driveway going into the park will be slightly realigned and graveled. The project will also include removal, repair and replacement of chainlink fence, installation of 122 LF of timber guardrail, a new vehicle barrier gate and 70 LF of 3 rail wooden fence. Cast-in-Place concrete includes the demolition and replacement of sidewalks and curb and the new construction of driveway aprons. Water and sanitary systems will not be impacted.
