Water Conservation Legislative Update

Due to improved hydrologic conditions, the state has said that “the unprecedented mandatory state-driven conservation standards in place over the last ten months must transition to conservation standards based on supply reliability considerations at the local level.” The new emergency regulation, adopted by the State Water Resources Control Board on May 18, 2016, will remain in effect until at least January 2017. Although state requirements have eased in some areas, the state declared drought emergency has not been lifted. City of Davis remains committed to meeting the mandatory conservation goals of reducing water use by 20% by 2020 as enacted through the Water Conservation Act of 2009 and additionally meeting the City’s goal of 20% below the 20% by 2020 goal, a target of 134 gpcd (gallons per capita day).

The newly adopted regulation requires locally developed conservation standards to be based upon each agency’s specific circumstances. Local water agencies must ensure a three-year water supply, assuming three additional dry years, and each agency is required to meet a conservation standard equal to the amount of water supply shortage, based on the calculation of the three-year supply. The state’s requirement for the City of Davis has been reduced from the current 25% to 0% due to a stable local supply of groundwater and surface water sources. Having a dual supply system of surface water and groundwater provides the City with greater water supply flexibility and more resiliency in times of drought.

Current state mandated end user restrictions on water use remain in effect and are likely to become permanent.  Mandatory conservation measures to prevent water waste will remain in effect for the City of Davis through the end of the current State Emergency Regulation. During this time, staff will work with the Natural Resource Commission Water Subcommittee and the public to update the City’s Water Shortage Contingency Plan (WSCP), determine which local water waste provisions should become permanent in the revised plan and will incorporate any permanent state-wide restrictions into the plan. The mandatory conservation measures for the City of Davis that have been in effect over the past year and will remain in effect during the current Emergency Regulation are listed under "Mandatory Water Use Restrictions" below.
