<br />Table 6-2 shows the City’s projected supplies during normal, single dry and multiple dry years through 2045
<br />based on the assumptions in the City’s 2020 UWMP which assumes implementation of the Bay-Delta Plan
<br />Amendment.

<br />
<br />The water supply estimates provided in Table 6-2 use the best available data at the time the City’s 2020 UWMP
<br />was prepared, but do not account for the following factors:
<br />
<br /> Potential changes to the implementation of the Bay-Delta Plan Amendment as discussed in Section 6.1.1
<br />of this WSA
<br /> Climate change impacts on the SFPUC RWS
<br /> Potential delays in completion of the WSIP6
<br />
<br />For comparison purposes, the SFPUC 2020 UWMP also evaluated a scenario without implementation of the Bay-
<br />Delta Plan Amendment. Table 6-3 shows the City’s projected supplies during normal, single dry and multiple dry
<br />years for 2025 through 2045 assuming that the Bay-Delta Plan Amendment is not implemented. SFPUC’s analysis
<br />indicated that it would be able to meet 100 percent of the wholesale projected purchases during all year types
<br />through 2045 except during the fourth and fifth consecutive dry years for base year 2045 when a 11.1 percent
<br />supply shortfall is projected for the City7.
<br />
<br />
<br />
<br />6 The San Francisco portion of the WSIP is 100 percent complete as of October 2020. The Regional portion of the WSIP is
<br />approximately 99 percent complete. The current forecasted date to complete the overall WSIP is May 2023.
<br />
<br />7 The projected purchases for Redwood City that are used in SFPUC’s analysis for the scenario without implementation of
<br />the Bay-Delta Plan Amendment vary slightly from the demands projected in Redwood City’s 2020 UWMP. Therefore,
<br />although SFPUC projects it can meet 100 percent of Redwood City’s purchases, except for the fourth and fifth consecutive
<br />dry years for base year 2045, slight supply shortfalls (1 to 2 percent) are projected for the City in dry years prior to 2045,
<br />as further discussed in Section 7.
