  5. The Yolo Subbasin Groundwater Agency Boundary Shapefile is from DWR's BBM 2016 Update; however, RD 999's 200-acre triangle has been cut out to ensure there is no overlap. REASON FOR THE GSA BOUNDARY EXCEEDING THE LOCAL AGENCY SERVICE AREA BOUNDARY: The University of California, Davis is participating in the Yolo Subbasin Groundwater Agency as an Affiliated Party via an MOU with the Yolo Subbasin Groundwater Agency JPA. Since they are not a local agency by the definition of SGMA, the Yolo Subbasin Groundwater Agency is entering into an MOU with Solano County to ensure sustainable groundwater management within the Yolo Subbasin portion of Solano County (within UC Davis's property). Please see the attached resolution approving entering into an MOU with the County of Solano. Also, as part of this notice, Dunnigan Water District, Reclamation District No. 108, and Reclamation District No. 787 are rescinding their GSA notifications since they chose to be members of the Yolo Subbasin Groundwater Agency JPA. Please see the attached letters for rescinding.
