Adopt the Water Supply Master Plan 2050.
Body
SUMMARY:
The Water Supply Master Plan (WSMP) is Santa Clara Valley Water District's (Valley Water) guiding document for long-term water supply investments to ensure water supply reliability for Santa Clara County. Updated approximately every five years, this long-range plan assesses projected future county-wide demands and evaluates and recommends water supply and infrastructure projects to meet those demands to achieve Valley Water's level of service goal through the planning horizon. Valley Water's Level of Service (LOS) goal, as established in Board Ends Policy E-2, is to "Meet 100 percent of annual water demand during non-drought years and at least 80 percent of demand in drought years."

During the plan development, staff have presented five updates to the Board of Directors (Board) as well as appropriate committees and advisory committees. Following the September Board update, which incorporated public and Board comments received, staff finalized the plan in response to feedback from the Board. The final WSMP 2050 is attached (Attachment 1).
