Water Resources in Los Angeles County

Water

Climate change impacts will likely mean less certain water supplies for the Los Angeles region.  Water resources in Los Angeles County include imported water, local native water, stormwater and waste water.  Water is managed and used differently across the region, and much of the region is supplied by water companies that are special districts whose boundaries do not align with political jurisdictions.  Researchers are developing a comprehensive database of all water managers in the region, the organizational structure of each entity (public, private, wholesale and retail) and different price structures to be able to determine whether water prices vary widely across the County.  In addition, researchers are conducting measurements to determine outdoor water use by census block group and land use type in the City of Los Angeles.  The aim is to better understand who is using how much water, and where, as well as to provide a definitive compendium accompanied by interactive GIS maps, of water management in the region.

climate change in los angeles county: grid vulnerability to extreme heat

Climate Change in Los Angeles County: Grid Vulnerability to Extreme Heat

In this project, UCLA and Arizona State University researchers developed a sophisticated and in-depth description of future electricity demand, grid response, and vulnerability due to increased heat events in Southern California Edison territory under current and future climate scenarios. The project's findings enable innovative grid management and operation strategies and identify adaptation guidance.
