LACSD North Bay Pump Station

Kelsey Structural is providing the design of the new North Bay Pump Station for the Lake Arrowhead Community Services District in Lake Arrowhead, CA.  Design includes a new, two-level, below grade concrete pump station, retrofit of an existing CMU electrical room, and new CMU bathrooms.  The new pump station is located in one of the highest seismic regions in California and is also just a few hundred feet from the lake shore which required design considerations for groundwater and extreme seismic ground motions.  Sloping backfill and buoyancy were also design concerns that were accounted for when sizing the concrete walls and foundations.  Waterstops and stringent reinforcement spacing requirements were used to help ensure a watertight and crack-free structure to increase the longevity of the pump station.
