1 Cost Sharing Agreement For The Los Vaqueros Reservoir Expansion Project Planning ACWD Board Meeting December 8, 2016

2 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

3 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

4 LVE Phase 2 Expansion Costs Capital cost Dam raise, pumps & conveyance improvements Transfer-Bethany Pipeline $500M to $600M $150M to $200M 4

5 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

6 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

7 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

8 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

9 Alameda County Water District Resolution to Authorize the Submittal of an Alternative to a Groundwater Sustainability Plan for the Niles Cone Subbasin and Declaring this Action Exempt from CEQA December Month, Day, 8, Year 2016

10 Sustainable Groundwater Management Act (SGMA) Signed into law on September 16, 2014 The District is identified in SGMA as an Exclusive Local Agency Niles Cone Subbasin is a Medium Priority Basin (therefore, subject to SGMA) Provides for formation of local Groundwater Sustainability Agencies (GSAs) Requires groundwater sustainability plans: Alternative to Groundwater Sustainability Plan Groundwater Sustainability Plan 2

12 Update on Groundwater Sustainability Agency (GSA) Formation November 10, 2016, the Board decided to become the GSA for the Niles Cone Subbasin November 21, 2016, GSA submittal received by DWR. November 22, 2016, letters sent to 18 agencies and approximately 100 well owners/operators. December 2, 2016, District s GSA submittal posted on DWR s website. 4

13 Alternative and Groundwater Sustainability Plan Timing Deadline to submit an Alternative to a Groundwater Sustainability Plan (Alternative) is January 1, If District doesn t submit an Alternative, then the Niles Cone Subbasin must be managed under a Groundwater Sustainability Plan by January 31,

14 Alternative to a Groundwater Sustainability Plan (Alternative) An Alternative may be based on any of the following: Groundwater Management Plan (AB 3030) or plan developed pursuant to other law authorizing groundwater management. Management pursuant to an adjudication action. An analysis of basin conditions that demonstrates that the basin has operated within its sustainable yield over a period of at least 10 years. 6

15 Groundwater Sustainability Plan Emergency Regulations Approved by Office of Administrative Law on August 15, Provided additional information for Alternative requirements. Webinar demonstrating the Alternative reporting system on December 2, Alternative reporting system available to agency s on December 5,

16 Bases for Submitting an Alternative- Plan Developed Pursuant to Other Law Authorizing Groundwater Management Replenishment Assessment Act of Alameda County Water District County Water District Law (Water Code et seq.) Existing Plan Core Documents Groundwater Management Policy Survey Report on Groundwater Conditions Groundwater Monitoring Report 8

17 Bases for Submitting an Alternative- Analysis of Basin Conditions Demonstrating the basin has operated within its sustainable yield over a period of at least 10 years. Existing plan core documents support this analysis. Survey Report on Groundwater Conditions Groundwater Monitoring Report 9

18 Alternative Submittal Reflects existing recognized authority and framework for management of groundwater. Continues the District s existing groundwater management practices/programs. Preserves the successful sustainable management already being performed by the District. 10

19 10 Year Analysis Analysis simply compiles existing information from various District programs, practices, and documents. Includes technical information from existing hydrogeological studies (DWR, District, etc.). Includes output from the Integrated Groundwater Surface Water Model which was created through a joint project between EBMUD and the District, with the City of Hayward s cooperation. 11

31 Key Requirements of an Alternative and the District s Management Efforts Submitted by a Local agency, GSA, or Watermaster The District is an Exclusive Local Agency and a GSA. An Alternative as described in Water Code Section (b) The District has in place a plan developed pursuant to laws authorizing groundwater management. The District has an analysis of basin conditions that demonstrates that the Niles Cone Subbasin has operated within its sustainable yield over a period of at least 10 years. 23

32 Key Requirements of an Alternative and the District s Management Efforts (Cont.) Functional Equivalency Requirement The District s existing groundwater management efforts and programs for the Niles Cone Subbasin satisfy the objectives of SGMA. Applies to the entire basin & CASGEM compliant The District manages the entire basin and is CASGEM compliant. 24

33 Recent Information from DWR s 12/2/16 Webinar Informed that an agency is only allowed to select one type of Alternative when submitting. However, a local agency is allowed to submit more than one Alternative. As previously mentioned, the District satisfies two of the three bases for submitting an Alternative, and therefore will submit an Alternative for each bases. 25

34 Alternative Submittal Preserves and continues the District s existing and successful sustainable groundwater management. Accomplished by continuing groundwater management practices and programs under pre-existing authority by which the District carries out groundwater management efforts. 26

35 Alternative Submittal and CEQA Determination Is not a project under the California Environmental Quality Act (CEQA), or alternatively is exempt from CEQA: Continues existing uses which do not result in a change in management of groundwater resources. Submitting an Alternative does not have a significant effect on the environment. Expressly exempt pursuant to Water Code Section in the SGMA regulations. Authorizes the District s continued ability to assure the maintenance, restoration, or enhancement of the Niles Cone Groundwater Basin while balancing and protecting environmental and natural resources. 27

36 Staff Recommendation Recommendation by motion, adopt a resolution authorizing staff to submit an Alternative to a Groundwater Sustainability Plan for Niles Cone Subbasin and declaring this action exempt from the California Environmental Quality Act. 28

37 Next Steps The District will submit an Alternative to a Groundwater Sustainability Plan prior to the January 1, 2017, deadline. 1.
