CHAPTER 5 – BASELINES AND TARGETS

The UWMPA requires that retail agencies provide a description of methods used for calculating

their baseline consumption as well as target water consumption. For the 2015 UWMP, the

agencies are required to show if the 2015 interim water use target was achieved and if the agency

is on track to achieve the 2020 water use target set forth in the 2010 UWMP.

5.1 2010 UWMP BASELINE AND TARGETS

Senate Bill X7-7 (SBX7-7) was approved by the Governor of California on November 10, 2009,

and requires urban water suppliers to set target goals for water conservation. Water suppliers

must meet the “20X2020” goals set forth by Governor Schwarzenegger of reducing per capita

consumption by 20 percent by the year 2020.

The evaluation of a supply source or storage needs for future growth is commonly achieved by

evaluating past water consumption on a per person basis. The future needs of the supply source

can then be evaluated by applying the per capita consumption rate, expressed as gallons per

capita per day (gpcd), to the projected population.

Table 5-1

summarizes the baseline periods

and per capita water use targets determined as part of the SBX7-7 calculations. The City had an

average gpcd of 192 from 1995 to 2000, while the average from 2001 to 2010 remained relatively

flat at approximately 200 gpcd. Conservation efforts were successful in lowering the water

consumption to a per capita water consumption rate of 123 gpcd in the year 2015.

It should be noted that the Governor of California released Executive Order (EO) B-37-16 on May

, 2016 regarding the on-going drought conditions that are affecting large portions of the state.

EO B-37-16 addresses the previous Executive Orders from 2014 and 2015, and that those

Order’s remain in effect. As part of this order, the Department of Water Resources (DWR), in

conjunction with the State Water Resources Control Board, must revise urban water use target

framework to develop new targets that build off of the “20x2020” SB X7-7 requirements. The
