<br />(a) Includes projected potable water supply from the SFPUC RWS (based on projected purchases) and projected recycled water
<br />supply (see Table 5-1).
<br />(b) Source: Redwood City 2020 UWMP, Table 7-4.
<br />(c) Source: BAWSCA Drought Allocation Tables by Agency (Table A: Wholesale RWS Actual Purchases in 2020 and Projected
<br />Purchases for 2025, 2030, 2035, 2040 and 2045), dated April 1, 2021.
<br />(d) An 11.1 percent reduction in supply from the SFPUC RWS is projected for the City in the fourth and fifth years of a multiple
<br />dry year drought, but not until 2045 (BAWSCA Drought Allocation Tables by Agency (Table O2: Individual Agency Drought
<br />Allocations, Base Year 2045, Without Bay-Delta Plan), dated April 1, 2021.)
<br />
<br />As required under SB 610, in light of these identified water supply shortages, Section 7 of this WSA describes the
<br />City’s proposals for reducing water demands and developing additional water supplies, including measures that
<br />are being undertaken to acquire and develop those water supplies.
<br />7.0 Comparison of Water Supply and Demand
<br />10910(c)(4) If the city or county is required to comply with this part pursuant to subdivision (b), the water
<br />supply assessment for the project shall include a discussion with regard to whether the total projected
<br />water supplies, determined to be available by the city or county for the project during normal, single dry,
<br />and multiple dry water years during a 20-year projection, will meet the projected water demand associated
<br />with the proposed project, in addition to existing and planned future uses, including agricultural and
<br />manufacturing uses.
<br />
<br />10911 (a) If, as a result of its assessment, the public water system concludes that its water supplies are, or
<br />will be, insufficient, the public water system shall provide to the city or county its plans for acquiring
<br />additional water supplies, setting forth the measures that are being undertaken to acquire and develop
<br />those water supplies.
<br />
<br />Because of the uncertainties surrounding the implementation of the Bay-Delta Plan Amendment, this WSA
<br />presents findings for two scenarios, one assuming the Bay-Delta Plan Amendment is implemented and one
<br />assuming that the Bay-Delta Plan Amendment is not implemented.
<br />
<br />Table 7-1 summarizes the scenario where it is assumed the Bay-Delta Plan Amendment is implemented. Under
<br />this scenario, significant supply shortfalls are projected in dry years for all agencies that receive water supplies
<br />from the SFPUC RWS. For the City, supply shortfalls are projected in single dry years (ranging from 32 to 40
<br />percent) and in multiple dry years (ranging from 32 to 47 percent) through 2045.
