Contract 19-058-240

In June 2019, the State Water Board adopted Resolution Number 2019-0029, authorizing a contract to support the environmental and economic analysis of new water efficiency standards.

The California Department of General Services approved Contract 19-058-240 on November 1, 2019. California State University (CSU) Sacramento will be leading the work to generate water use scenarios given varying and reasonably foreseeable climatic and economic conditions. The scenarios will inform both the environmental and economic impact analyses.

Teams at the University of California (UC) Los Angeles, UC Davis, and CSU Sacramento will carry out the environmental analyses, which include meeting CEQA obligations and evaluating impacts to local wastewater management, developed and natural parklands, and urban tree health. Teams at CSU Humboldt and CSU Sacramento will carry out the economic impact analysis.
