Upper Stone Canyon Reservoir Water Quality Improvement Project
Document Type
EIR - Draft EIR

Document Description
To help ensure the quality, reliability, and stability of the City of Los Angeles drinking water supply and to ensure compliance with updated EPA water quality standards, LADWP proposes to construct a new buried concrete-covered reservoir to replace the existing uncovered Upper Stone Canyon Reservoir, in essentially the same location as the existing reservoir. The buried reservoir would provide an equal amount of potable water storage (138 million gallons [MG]) as is available in the existing reservoir. A maximum depth of 3 feet of topsoil would be placed over the buried reservoir, and shallow-rooting native plant species typical of the canyon environment and surrounding area would be installed. After completion of project construction, public access consisting of pedestrian trails would be provided in portions of the Stone Canyon Reservoir Complex.
