Cost Sharing Agreement For The Los Vaqueros Reservoir Expansion Project Planning ACWD Board Meeting December 8, 2016
Los Vaqueros Reservoir (LV) Owned and operated by CCWD Off-stream reservoir, adjacent to the Delta. 165 Thousand Acre Feet (TAF) Filled with CVP water and CCWD local water from the Delta CCWD is planning a second expansion to 275 TAF and is seeking partners to participate 2
Phase 2 Expansion Details Proposed expansion to 275 TAF Construction of a Transfer-Bethany Pipeline New diversion and conveyance facilities CCWD uses reservoir heavily for water quality benefits (poor Delta WQ in summer months) Screened Diversions reduced fish impacts More diversion points, able to shift in response to WQ and environmental issues 3
LVE Phase 2 Expansion Costs Capital cost Dam raise, pumps & conveyance improvements Transfer-Bethany Pipeline $500M to $600M $150M to $200M 4
ACWD / CCWD History ACWD participated in the 2001 Phase 1 Expansion Studies but declined to participate in the actual Project due to insufficiently demonstrated benefit for cost CCWD expanded LV in 2012 from 100 to 165 TAF. Since 2013, ACWD has been working with CCWD on reliability concepts: Purchased and transferred 5,000 AF of water by exchange during the 2014 drought Acquired regulatory permissions to exchange CVP and SWP supplies in order to store SWP water in LV (not executed.) 5
Partnering Opportunity in Phase 2 Expansion ACWD has identified Expanded Los Vaqueros (ELV) as a water supply reliability initiative. Benefits include: South of Delta Storage of SWP supply that is upstream of ACWD Potential new supply (CCWD s delta surplus water right ) Facilitate exchanges amongst other partnering agencies Studying 30 TAF (10 emergency + 20 operational) Current Partners: BAWSCA / SFPUC, BBID, Brentwood, EBMUD, SLDMWA, SCVWD, Zone7, ECCID, GWD Cost: $100,000 plus in-kind contribution 6
Agreement to Participate in Planning The planning effort includes preparing: Draft Federal Feasibility Report Draft Supplemental EIS / EIR Funding application to CWC for Prop 1 implementation funds Participation now preserves opportunity to partner Participating now does not obligate us beyond the currently proposed agreement Should CWC funding be received, the next steps would be: Finalize partners, negotiate terms Finalize EIS/EIR Design & Construction 7
Staff Recommendation By motion authorize the General Manager to enter into a cost sharing agreement with the Contra Costa Water District in an amount not to exceed $100,000 for professional services needed to prepare a California Water Commission Funding Application for the Los Vaqueros Reservoir Expansion Project. 8
