For this project KOA installed a diversion structure, pump station, and infiltration field to divert low-flow storm drain system runoff from beach areas to a subsurface percolation field. Construction took place in the developed area around the pier, requiring significant coordination with City staff, lifeguards, and businesses. Permitees include the City, Los Angeles County and the Coastal Commission. The project was financed with ARRA funding. KOA Corporation provided the construction project management and inspection services, as well as assistance for federal-aid funding requirements and reporting.
