Body
SUMMARY:
This item provides an opportunity for the Board and the public to receive information and discuss ongoing Delta planning efforts that are critical both to restoring the health of the Delta ecosystem, and to ensuring the long-term reliability of water supplies conveyed through the Delta.
At the February 22, 2016 Bay Delta Conservation Plan (BDCP) Ad Hoc Committee meeting, staff presented the first phase of a comparison of costs and benefits of several water supply alternatives to the California WaterFix (WaterFix) (Attachment 1). In this updated analysis, the comparison is expanded to include (1) analysis of purchasing additional "permanent" contract or water right water as a new potential alternative to the WaterFix; (2) a breakdown of the cost components for the additional conservation and the purified water program options, as requested by members of the BDCP Ad Hoc Committee on February 22; and (3) a separate evaluation of WaterFix performance without baseline potable reuse compared to 45,000 acre-feet (AF) of potable reuse.
Staff plans to bring further updates to the Board on the WaterFix economic analysis once further information becomes available, including proposed specific methods for allocation of costs among WaterFix participants. The Board will also receive updates from staff on the economic analysis of the Expedited Purified Water Program once substantial work has been completed in the preliminary engineering phase of that program. Further, staff plans to present the Board with an economic analysis of various storage project alternatives in December 2016.
