Phelan Chromium-6 Mitigation Project
Kelsey Structural is providing structural design for the Phelan and Piñon Hills CSD (PPHCSD) Chromium-6 Mitigation Project. The project’s goal is to expand the current water storage capacity and conveyance of the PPHCSD to allow for increased detention time and well water mixing to lower the levels of Chromium-6 to acceptable levels in the drinking water. Work includes the design of (2) CMU booster pump station facilities, (2) steel tank foundations, multiple well canopy foundations, and miscellaneous site equipment pads and anchorage.
Kelsey Structural is providing part of the structural design for the NCCS project as SLBE subconsultant. The design includes a pipeline utility bridge spanning 100’ over an existing railway under the existing Miramar Road concrete bridge. The existing concrete bridge will be analyzed for the additional weight and new penetrations through the existing concrete abutments. The design will also include a dechlorination facility consisting of a CMU building to protect (2) chemical tanks, and the design of multiple concrete below grade metering vaults and retaining walls.
