HomeMy WebLinkAbout9 Contract with GEI Consulting for Martis GMP Annual Report AGENDA ITEM #9 MEETING DATE: November 2, 2022 TO: Board of Directors FROM: Steven Poncelet, Public Information and Strategic Affairs Director SUBJECT: Consideration of a Contract with GEI Consultants for Hydrogeologic Consulting Services APPROVED BY ___________ Brian C. Wright, General Manager RECOMMENDATION: Authorize the General Manager to execute a contract with GEI Consultants for the Martis Valley GMP Annual Report in an amount of $21,500, plus a 10% change order authorization of $2,150, for a total not to exceed contract amount of $23,650. DISCUSSION: The District has a long history of stewardship and collaboration in managing water resources. A major tenant of local water resource management has been to use the best available science to inform the decision making process. This has resulted in decades of monitoring and scientific study, including the Desert Research Institute’s Martis Valley groundwater model/report as part of the Federal Truckee River Basin Study. This effort was supported by the District, Northstar Community Services District - NCSD, and Placer County Water Agency - PCWA (Local Water Agencies) and was a key component of the collaboratively adopted 2013 Martis Valley Groundwater Management Plan (GMP). In 2014, California passed into law the Sustainable Groundwater Management Act (SGMA) which applied to all Medium and higher Priority basins (Martis Valley was at the time designated Medium Priority). This, in effect, put the implementation of the 2013 GMP on hold. The District, PCWA, NCSD, Town of Truckee, Nevada County and Placer County (local SGMA agencies) in the Martis Valley Groundwater Basin (MVGB) put forth an Alternative Submittal in December, 2016 in compliance SGMA. The local SGMA agencies hired a licensed engineering firm (GEl Consultants) to certify the MVGB Alternative Page 1 of 4 Submittal. The Alternative Submittal and supporting GEl Consultants report document that the MVGB has operated within its sustainable yield for at least 25 years. The MVGB Alternative Submittal was submitted in December, 2016. Subsequently, in April of 2017, a first-year SGMA Annual Report was submitted while the on-going review by the California Department of Water Resources (DWR) of the Alternative Submittal continued. In early 2019, while Alternative Submittal review still continued, DWR was required to review basin prioritization. The MVGB was initially again prioritized Medium but, upon review and engagement with DWR by the local SGMA agencies, the MVGB was re- prioritized to ‘Very Low’ and was no longer required to comply with SGMA. The local SGMA agencies agreed to formally withdraw the Alternative Submittal from DWR consideration and to go back to the 2013 Martis Valley GMP framework, including reconvening the Stakeholder Working Group which was active in the development of the plan. It is believed that this local GMP framework is a much more effective and efficient process to manage groundwater resources than the heavy hand of SGMA regulation. The three Local Water Agencies worked with our local partners to develop a plan to go back to the GMP framework. This included updating the Stakeholder Working Group list to reflect the local agencies or groups with direct interest in Martis Valley groundwater resources. In general, the stakeholders fall into three categories: local public agencies; major water users/pumpers; and local non-profits/interest group. A GMP Stakeholder Working Group kick-off meeting was held on October 3, 2019 where the three Local Water Agencies reviewed the 2013 Martis Valley GMP and the key meetings and actions that would occur going forward. This includes an annual report tracking the performance and long-term sustainability of the groundwater basin along with an update to the GMP every five years. Given the significant amount of work and reporting during the SGMA Alternative Submittal, it was agreed that the start of the GMP would now be 2019. The Local Water Agencies solicited a proposal from GEl Consultants who had previously done work in the Martis Valley on sustainable yield, the SGMA Alternative Submittal, and the SGMA Annual Report. GEl Consultants is very familiar with both the Martis Valley and the Local Water Agencies. The Local Water Agencies agreed to split the costs of the annual reports equally (i.e. 1/3 share). The District’s Board awarded a contract to GEI Consultants in December of 2019 for the GMP annual report to cover water years 2017/2018 and 2018/2019. The two year report was presented to the Martis Valley Stakeholder Working Group in March of 2021. The delay in completing the report and presentation to the Stakeholder Working Group was a result the transition from SGMA to a GMP framework along with the start of the COVID pandemic. Page 2 of 4 The District’s Board awarded a second contract to GEI Consultants in October of 2021 to cover water years 2019/2020 and 2020/2021. Again, due mostly to the impacts of COVID, a two year annual report was prepared and presented to the Stakeholder Working Group in May of 2022. The latest report continues to document that the Local Water Agencies are managing the basin well within the sustainable yield estimates (~8,000 Acre-Feet per Year water use verses 22,000 AFY sustainable yield) and that groundwater levels remain largely stable. That being said, the last two water years have been classified as very dry with 2020/2021 water year having the lowest precipitation in the last twenty years. As expected, with a drop in precipitation there is a corresponding drop in groundwater levels. The MVGB has historically recovered from drought quickly and the Local Water Agencies will continue to monitor the impacts of drought and recovery on Martis Valley aquifer. One proactive step that the Local Water Agencies took a few years back was to change from only monitoring groundwater levels twice per year (spring and fall) to a regime of monthly monitoring. The new data set creates the opportunity to begin understanding how the aquifer responds to drought and seasonal fluctuations. It is important to note, however, that this is the first drought that monthly data is being collected so there is no direct comparison the decades of previous groundwater monitoring but we are developing an important tool for future droughts. ANALYSIS The Local Water Agencies have met and decided to continue to work with GEI Consultants for the annual report and are now back on an annual cycle with the next report covering water year 2021/2022. The Stakeholder Working Group meeting is planned for spring of 2023. The five year update of the GMP is planned for 2024. The GEI proposal for the Martis Valley GMP Annual Report is $21,500 which would be split equally amongst the Local Water Agencies. The GEI Consultants proposal is Attachment 1.
