<br />NOTES:
<br />It is conservatively assumed that a five consecutive dry year scenario is a repeat of the single dry year
<br />(106% of projected normal year values) over five consecutive years. The 2025 column assesses supply
<br />and demand for FY 2020-21 through FY 2024-25; the 2030 column assesses FY 2025-26 through FY
<br />2029-30 and so forth, in order to end the water service reliability assessment in FY 2044-45.
<br />Groundwater is sustainably managed through the BPP and robust management measures (Section
<br />6.3.4 and Appendix G), direct and indirect recycled water uses provide additional local supply (Section
<br />6.6), and based on MET's UWMP, imported water is available to close any potable water supply gap
<br />that local sources cannot meet (Section 7.5.1).
