Prior to December 2015, properties either completely or partially within the site of the proposed reservoir (Texas Hill Reservoir Take Line) were residentially-zoned. However, those residential zones had long been inconsistent with the County's Open Space (OS) General Plan Land Use Designation, which prohibits single family residential structures (including residential accessory structures).
On December 15, 2015, the Board adopted the Zoning Ordinance Update (ZOU) to make the Zoning Map consistent with the General Plan as mandated by state law. As part of the 2015 ZOU, all parcels within the Texas Hill Reservoir Take Line were rezoned to either Recreational Facility, Low Intensity (RF-L) or Open Space (OS) which prohibit residential uses. Therefore, effective January 2016, all property owners within the Take Line were prohibited from applying for any residential building permits (all types).
On March 17, 2020, after receiving confirmation from the regional water purveyor, the El Dorado Irrigation District (EID), that their agency had no plans for the foreseeable future to construct the proposed Texas Hill Reservoir project and therefore EID would support a rezone and General Plan amendment project for lands within the Texas Hill Reservoir Take Line, the Board of Supervisors directed Long Range Planning staff to process the required General Plan Amendment, Rezones and associated environmental documents. As proposed, the project would re-allow residential uses on affected parcels consistent with the uses that were previously allowed per the Zoning Map before December 15, 2015 (File 20-0326, Attachment A).
