Document Description
To ensure the quality, reliability, and stability of the City of Los Angeles drinking water supply, including compliance with updated US EPA water quality standards, LADWP proposes to replace the uncovered Upper Stone Canyon Reservoir with a buried concrete storage structure sited essentially within the existing reservoir. This concrete storage structure would provide approximately 81 million gallons of potable water storage. The area atop the concrete storage structure would be planted, and a pedestrian trail system, picnic area, restroom facilities, and a parking lot may be established within the Stone Canyon Reservoir complex to provide for passive recreation activity. After completion of project construction, the trails within the site would be open to public use, and recreation functions would be maintained and operated by the LADRP.
