Maximize value of familiar structures and relationships; 2. Acknowledge all key interests of eligible local agencies; 3. Respect legally recognized rights; 4. Anticipate GSA requirements; 5. Make use of basin boundary adjustments; 6. Comply with SGMA regulations; 7. Identify opportunities to address interests of current non-GSA stakeholders; 8. Distribute costs in an equitable manner as possible; 9. Respect mutual interests in maintaining independent decision-making; and WHEREAS, the "white areas" of Butte County within the four sub-basins are not represented by other eligible local agencies and will therefore be represented by Butte County unless these areas choose to annex to an eligible local agency or form a new one; and WHEREAS, Butte Environmental Council (BEC) as a local non-profit engaged in Butte County water advocacy since 1975 has taken an active role in the collaborative SGMA process since it began in 2015 and continues to engage in all aspects of SGMA implementation and governance. Butte Environmental Council is uniquely positioned to represent key interests in SGMA and supports the interests of beneficial users of groundwater including domestic groundwater users, and the environment in decision making processes; and; WHEREAS,the Butte Environmental Council recognizes and respects the leadership of Butte County and it its efforts to create a workable and cooperative structure to discuss GSP; and WHEREAS,the Butte Environmental Council recognizes and respects the leadership of Butte County to move forward to complete a comprehensive GSP by January 31, 2022; and WHEREAS, inherent in this process and timeframe Butte County will endeavor through the stakeholder process to develop a governance structure,for SGMA oversight of each of the four subbasins within Butte County consistent with the nine principles enumerated above; and WHEREAS, principle number 7 above, recognizes that the interests of non-GSA stakeholders such as domestic pumpers, and the environment should be addressed; and WHEREAS, Butte County recognizes the value of input and participation in the SGMA process by the Butte Environmental Council, which has been committed to protecting and defending the land, air and water of Butte County through action, education and advocacy since 1975, and is comprised of more than 600 community members dedicated to our local environment. NOW,THEREFORE, BE IT RESOLVED: 1. The County of Butte will continue to work with stakeholders within Butte County utilizing a collaborative process to establish a governance structure and ultimately develop a Groundwater Sustainability Plan, and the Butte Environmental Council will openly and earnestly participate and cooperate in that process as a representative for the environment at large. 2. As governance structures for implementation of SGMA are discussed among, and ultimately decided by all eligible local agencies within the four subbasins, the County of Butte and the Butte Environmental Council will work together to advocate for and implement governance structures in each subbasin that will recognize and allow for appropriate representation of domestic pumpers, and the environment at large within each governance structure in compliance with SGMA. PASSED AND ADOPTED by the Butte County Board of Supervisors this [DAY] day of[MONTH], 2018 by the following vote: AYES: NOES: ABSENT: NOT VOTING: Steve Lambert, Chair Board of Supervisors ATTEST: Shari McCracken, Chief Administrative Officer And Clerk of the Board of Supervisors By: Deputy GPAC Agenda I Item #10 { Management Areas § 357.. Definitions (r) "Management area" refers to an area within a basin for which the Plan may identify different minimum thresholds, measurable objectives, monitoring, or projects and management actions based on differences in water use sector, water source type, geology, aquifer characteristics, or other factors. § 354.20. Management Areas (a) Each Agency may define one or more management areas within a basin if the Agency has determined that.creation of management areas will facilitate implementation of the Plan. Management areas may define different minimum thresholds and be operated to different measurable objectives than the basin at large, provided that undesirable results are defined consistently throughout the basin. (b) A basin that includes one or more management areas shall describe the following in the Plan: (1) The reason for the creation of each management area. (2) The minimum thresholds and measurable objectives established for each management area, and an explanation of the rationale for selecting those values, if different from the basin at large. (3) The level of monitoring and analysis appropriate for each management area. (4) An explanation of how the management area can operate under different minimum thresholds and measurable objectives without causing undesirable results outside the management area, if applicable. (c) If a Plan includes one or more management areas, the Plan shall include descriptions, maps, and other information required by this Subarticle sufficient to describe conditions in those areas. § 354.34. Monitoring Network (d) The monitoring network shall be designed to ensure adequate coverage of sustainability indicators. If management areas are established, the quantity and density of monitoring sites in those areas shall be sufficient to evaluate conditions of the basin setting and sustainable management criteria specific to that area. § 356.4. Periodic Evaluation by Agency (c) Elements of the Plan, including the basin setting, management areas, or the identification of undesirable results and the setting of minimum thresholds and measurable objectives, shall be reconsidered and revisions proposed, if necessary.
