Aliso Creek Urban Runoff |
PROJECT SUMMARYThe District proposes to capture and reuse approximately 500,000 gallons per day (gpd) (could be as high as 800,000 gpd) of urban runoff in Aliso Creek in Laguna Beach, California. The recovered urban runoff collected by the Aliso Creek urban runoff recovery, reuse and conservation project will be treated and reused by combining the water with recycled water produced at the Advanced Wastewater Treatment (AWT) System at the Coastal Treatment Plant (CTP). There will be an improvement to the water quality of the combined supply, making the AWT recycled water more usable as well as increasing the overall recycled water supply for South Laguna and Dana Point. Downstream improvements in water quality are expected at Aliso Beach County Park because a portion of the urban runoff will be removed from Aliso Creek and constituents removed from the runoff water will be discharged in the CTP outfall, approximately 8,000 feet offshore at a depth of approximately 170 feet. Removal of a portion of the urban runoff will also help to reduce excessive stream flow from urbanized areas and help to return stream flows in lower Aliso Creek to more natural levels. PROJECT LOCATIONThe project area is within the Aliso Creek Watershed downstream of the Aliso and Wood Canyons Wilderness Park and is approximately 1.5 miles from the confluence of the creek into the Pacific Ocean at Aliso Beach County Park, a popular beach destination and water sport location. PROJECT STATUSThe District has completed an environmental review of the project as required by the California Environmental Quality Act (CEQA) and certified a Mitigated Negative Declaration and Mitigation and Monitoring Plan. The District is in the process of securing permits needed for the project. PROJECT DOCUMENTS
