<br />WATER SUPPLY ASSESSMENT AUGUST 21, 2020
<br />• Each project and program to achieve the 75 percent BPP goal will be reviewed
<br />individually and assessed for their economic viability.
<br />The BPP goals mentioned above coincide with other management strategies as shown in
<br />OCWD's Long Term Facilities Plan (LTFP), the 2015 Groundwater Management Plan and the
<br />2020 Water Master Plan Report. These documents highlight OCWD's plans to ensure
<br />groundwater supply will be available into the future to support growing demands of its service
<br />area.
<br />As shown in Table 8 below, the City's available supply, including OCWD groundwater and
<br />Metropolitan imported water, will meet projected demand during normal, single dry and
<br />multiple dry years. For the City's 2015 UWMP, the normal dry year was selected as the City's
<br />2015 demand. A single -dry year is defined as a single year of no to minimal rainfall within a
<br />period that average precipitation is expected to occur. The City has documented that it is 100%
<br />reliable for single dry year demands from 2020 through 2040 with a demand increase of 6%
<br />using FY 2013-14 as the single dry -year. Multiple -dry years are defined as three or more years
<br />with minimal rainfall within a period of average precipitation. The City is capable of meeting all
<br />customers' demands with significant reserves held by Metropolitan, local groundwater supplies,
<br />and conservation in multiple dry years from 2020 through 2040 with a demand increase of 6%
<br />using FY 201 1-12 through FY 2013-14 as the driest years.
