�,,4-i REPORT To the Honorable Mayor and City Council From the City Manager April 4, 2005 � Subject Redwood City Water Supply Plan ReGOmmendation Receive information — No action required Background The San Francisco Public Utilities Commission (SFPUC) owns and operates the Hetch Hetchy regional water system, from which Redwood City purchases 100% of its current drinking water supply. Redwood City is over-drafting its contractual supply assurance by an average of 1,100 Acre-feet per year. The City Council has set a policy goal to erase this water supply deficit by the time the Master Sales Agreement with San Francisco expires in 2010. The State of California's 1984 Urban Water Management Planning Act ("The AcY') AB 797, requires every urban water supplier providing water for municipal purposes to more than 3,000 customers, or supplying more than 3,000 acre feet of water annually, to prepare and adopt an Urban Water Management Plan, the primary objective of which is to plan for the conservation and efficient use of water. In 2001 the City's Urban Water Management Plan (UWMP) was substantially updated to incorporate water use projections in the Redwood City Water Use Forecast 2000-2020, prepared by John Whitcomb, PhD, which the City Councii accepted on July 1, 2002. The amendment also conformed the UWMP to the City's then-pending draft General Plan Housing Element update, pending draft Downtown Plan Environmental Impact Report, and � proposed developments west of Highway 101. In 2003 the UWMP was updated again, and the Council approved the amendment, then authorized a water fund budget and rate adjustments necessary to implement the "active" conservation activities delineated in the new Plan, estimated to cost $4.1 million over a 5- year period. Chapter One of the UWMP describes past, current and projected water use for the City, and covers the planning horizon 2000 through 2020. The water demand projections include assumptions about plumbing code changes and increased water use efficiency that will occur with no city action or cost ("passive" conservation). Appendix B of the UWMP — Water Use Forecast 2000 to 2020 - provides a detailed tist of the "water use drivers" that are imbedded in the forecast model, which generated the Base Demand projections. Key drivers are: Population, potential new housing units, and employment estimates which link to growth in commercial water use (See attachment). _ _ _ _.. . _ ...._ �._._ _ ._ _.. r .
