Document Description
The City of Los Angeles is proposing to construct a stormwater diversion structures at the Rose Avenue storm drain, primary and secondary pump station systems, a pretreatment system to screen trash, sediment, oil and grease; an underground detention reservoir, and three force mains for flow conveyance. As sewer capacity allows, a portion of the flow, including dry weather flow, would be diverted to the sanitary sewer and ultimately to the Hyperion Treatment Plant. Another portion of the wet weather flow would be diverted to the underground reservoir where it would be held for ~72 hrs after a storm event passes and then discharged at a controlled rate to the sanitary sewer. The project also includes minor sanitary sewer upgrades southwest or Penmar Recreation Center. Phase II of the project would provide further treatment for beneficial use for landscape irrigation at Penmar Golf Course, Penmar Recreation Center and/or Marine Park.
