Providing reliable water supplies in drought conditions is an increasing challenge across Los Angeles County. The CWP defines water supply reliability as the ability to meet current and future needs 100% of the time, including during emergencies. The CWP targets indicate the desire for increases in water conservation and efficiency as well as the further development of local supplies to improve resilience in the face of both longer-term droughts as well as near-term emergencies. The targets reflect an alignment with the upcoming State Water Use Objectives, which are being developed by the State Water Resources Control Board (SWRCB) and will be released after this initial iteration of the CWP. Although imported water will play a vital role in Los Angeles County in the foreseeable future, increasing local sources of water promotes water supply diversity, autonomy, and reliability as well as long-term drought resilience. In addition, water use efficiency and local supplies provide environmental benefits by reducing energy consumption and improving local water quality as well as increasing local workforce. Near-term emergency resilience is equally important and greatly enhanced by maintaining sufficient levels of locally-developed and stored supplies throughout the County.
