IV. ENVIRONMENTAL IMPACT ANALYSIS L. UTILITIES AND SERVICES 1. WATER This section describes the utility supply and infrastructure that currently serve the project site and surrounding area, assesses potential impacts associated with the project on this supply and infrastructure, and identifies the need for improvements in order to serve the project and related development, if needed. Each utility issue is discussed in its own subsection (1. Water; 2. Sewer; 3. Solid Waste; 4. Electricity Supply; and 5. Natural Gas Supply). ENVIRONMENTAL SETTING Water Supplies The Los Angeles Department of Water and Power (LADWP) is responsible for ensuring that water demand within the City of Los Angeles is met and that State and Federal water quality standards are achieved. The City’s water supplies are derived from the following sources: 75 percent from the eastern Sierra Nevada Mountains by way of the Los Angeles Aqueduct (LAA) system, local groundwater, and 25 percent from purchases from the Metropolitan Water District of Southern California (MWD).1 In addition, water storage is essential for the LADWP to supply water during high demand conditions and provide for firefighting and emergencies. To serve the residents, businesses, and industry of Los Angeles, LADWP has more than 7,200 miles of pipelines, 680,000 water service connections, 59,000 fire hydrants, 100 reservoirs and tanks in the City, and eight storage reservoirs along LAA.2 Currently, the existing on-site uses consume an estimated 2,458 gallons of water per day (see Table IV.L- 1).
