10 WATER PLANNING COMMITTEE DISCUSSION OUTLINE Date: May 15, 217 Originator: Subject: Parag Kalaria - Water Resources URBAN WATER CONSERVATION REPORT BACKGROUND AND RECOMMENDATION Since June 214, Elsinore Valley Municipal Water District (EVMWD) has been providing monthly Water Conservation Reports to the State Water Resources Control Board (SWRCB) under the Urban Water Supplier Reporting requirements established, as part of the current drought conditions. On April 1, 215, Governor Brown signed Executive Order B-29-15, directing the State Water Resources Control Board (SWRCB) to impose restrictions to achieve a statewide 25 percent reduction in potable urban water usage as compared to the amount used in 213. Currently, State mandate s enforcement period is from July October 216. On June 21, 216, EVMWD submitted to the SWRCB its Water Supply Reliabilitycertification application (Stress Test) requesting for % water conservation target for the enforcement period June 216 January 217. On August 16, 216, SWCRB approved our application, and our current Water Conservation Target is %. On February 8, 217, SWRCB adopted an emergency water conservation regulation to amend and extend the May 18, 216 regulation. Compliance with the conservation standard extends through October, 217. During the meeting, staff will provide an update of the monthly urban water conservation report. ENVIRONMENTAL WORK STATUS Not applicable. FISCAL IMPACT 1 Discussion Items: #3.
