The objective of this scope of work is to identify a short list of one or more alternative plans that would achieve the project objectives. Data, tools and analytical results developed in Phase I of the Mokelumne Aquifer Recharge and Stora_e Project (.MARS) will be used to the extent possible and practicable in this work to minimize costs and provide consistency of analyses and results between the two efforts. In particular, the San Joaquin County IGSVf and the GIS originJly developed for Phase 1 MARS will serve as L` a basic analytical tools for this work. STAGE I - DEVELOP PROJECT BASIS Activities completed in this stage are intended to provide the nandamental knowledge and understanding required to support subsequent for^tulation of coherent alternative plans that would achieve the project objectives. Task A Evaluate Water ;Heeds and Potential Water Sources 1. Using the San Joaquin Counrl IGSM, evaluate dhe following: - Total yearly quantity of water required to stop saline intrusion and initiate basin storage recovery, - Minimum groundwater elevation(s) required to have no further saline intrusion (threshold elevation), - Annual average volume of water required to achieve threshold elevation in S years, 10 years ' - Annual average quantiry of water required to me;.t joint project goals with rroudwater elevations always above threshold elevation, - Dry year water supply if :00.000 aflyr is available in wee years, dry year water supply if 400,000 aflyr is available in wet years. - Describe the basis and evaluate the following potential water sources: 2. EB.MUD A.* a:;can River water service ceraract delivered froan the Folsom South Canal (FSC), as conditioned by the Hodge Decision. 3.

Possible assi;nmem or transfer of sure flings or reserved water rights on the Mokelumne, assuming inst earn Bows as specified in EB` UD's July 16, 1993 offer of se:Lle :fent to ) IHRC. For each potential source, describe existing water right conditions, crenare baseline monthly water availability hydrographs, and identify relevant reliability and i,:,plementabiiity issUes associated with water right priority, related regional water management initiatives, and apparent statutory and institutional constraints.

BACKGROUND INFORMATION: A committee, appointed by Supervisor Barber, has been working with East Bay Municipal Utility District (EBMUD) for approximately a year to develop the Water Banking/ Conjunctive Use Project. A copy of the Agreement initiating preliminary study is attached as Exhibit 1. The City of Lodi will be asked to sign this Agreement at a later date. All costs under this Agreement will be the responsibility of EBMUD and San Joaquin County. The major principles of the Project include: • stop the overdraft of the East San Joaquin groundwater basin • restore this groundwater basin to a reasonable level • stop saline intrusion • provide the water needs to the East San Joaquin Parties (ESJP) • supply EBMUD with dry -year water The ESJP include the following agencies- . - • Woodbridge Irrigation District (WID) • North San Joaquin Water Conservation District (NSJWCD) • Central San Joaquin County Water Conservation District (CSJCWCD) • Stockton East Water District (SEWD) • City of Lodi • City of Stockton • San Joaquin County Flood Control and Water Conservation District The ESJP Technical Committee, a subcommittee of the Water Policy Committee, is presently -working with EBMUD engineers to develop a formai work plan. As part of the work plan, some of the major water sources to be considered are: • wet -year Mokelumne River water supply • existing entitlements of ESJP from the Mokelumne and Calaveras rivers • EBMUD's American River supply APPROVED: THOMAS A- PETERSON r.ere�.e a.o.r City Manager CONJUSEAOC RAG East San Joaquin Parties/East Bay Municipal Utility District Jcint Conjun44ve Use Project (Information Only) June 7, 1995 Page 2 • USSR/SEWD/CSJWCD contracts • 1485 Water (treated wastewater from Stockton released to Delta) reclaimed wastewater from City of Lodi and City of Stockton Some of the needed facilities include an unlined canal between Folsom Canal and Farmington Canal, and new irrigation distribution systems to serve surface water in lieu of groundwater. A pian showing the canal alignment is attached as Exhibit 2. The total preliminary study project costs are approximately $630,000. These costs are to be shared equally between EBMUD and San Joaquin County. The majority of the work will be performed by Montgomery Watson consulting engineers. The ESJP Technical Committee has also retained Boyle Engineering as its consultant to work with them. The total County's share is approximately $315,000 and will be funded by the County using its Water Zone Investigation II funds. A time schedule for this work is attached as Exhibit 3. Also attached for your information is a document entitled `Undercurrents Developed by EBMUD and ESJP' which provides more general information on this joint project Andy Christensen, from WID, is the Chairman of the ESJP Technical Committee. He will be at the Council Meeting to help answer any questions you may have related to this project. FUNDING: San Joaquin County funds.
