Why a California Water “Fix?” Five Benefits for Southern California Protecting Southern California’s Investment: We’ve invested billions of dollars to build and maintain the State Water Project. Modernizing this system will help to protect this investment and this supply for decades. Minimizing Future Water Rates: Imported supplies – even with reinvestments such as California WaterFix – are less expensive than developing new local supplies. Thinking Long Term: California WaterFix will better capture available supplies from winter storms, helping to meet the needs of future generations. Preserving Jobs: Severe shortage could mean severe economic cost - a reliable water supply from Northern California would protect 1 nearly million jobs statewide. Advancing Statewide Progress: California WaterFix would advance water reliability statewide. 14

Why a California Water “Fix?” Five Benefits for Los Angeles County Sustaining Our Cities: Water from Northern California is the sole imported supply available to several cities in Los Angeles County, including the San Fernando Valley. Providing Local Groundwater: Many cities in Los Angeles County rely on water from Northern California to supplement local groundwater supplies. Promoting Local Supplies: The high-quality supply of water from Northern California allows areas such as the West and Central Basins to recycle water again and again to meet local demand. Surviving Droughts: Communities in Los Angeles County have relied on imported water more than ever during the ongoing drought as local supplies diminished. Capturing Big Storms: California WaterFix seeks to improve the ability to capture some of the state’s major storms and store it in groundwater banks and reservoirs for Los Angeles County in years of drought. 15
