AGSA Eligibility Determination

  1. The newly created Santa Clarita Valley Groundwater Sustainability Agency was formed under a Memorandum of Understanding from the following member agencies: The County of Los Angeles, City of Santa Clarita (land use agencies), Castaic Lake Water Agency (CLWA) (water wholesaler), Santa Clarita Water Division (SCWD), Newhall County Water District (NCWD), and Los Angeles County Waterworks District Number 36 (LACWD # 36) (water retailers). Collectively the combined service area covers the entire Santa Clara River Valley East Subbasin (SCRVES). CLWA, the water wholesaler acquires and distributes imported water from the SWP and other sources to water retailers in the SCRVES. The imported water is conveyed through SWP facilities under CLWA?s SWP water supply contract with the state?s Department of Water Resources. Under that contract CLWA has a long-term SWP water supply contract for 95,200 acre-feet (AF) of SWP Table A Amount. However, the availability of SWP supply fluctuates from year to year depending on precipitation, regulatory restrictions, legislative restrictions and operational conditions and is subject to substantial curtailment during dry years. CLWA has therefore entered in to water purchase agreements and water banking and exchange programs. CLWA is also the entity that has contracted with the Santa Clarita Valley Sanitation District for the purchase and distribution of recycled water to the water retailers. Additionally, CLWA also owns and operates two wells that treat perchlorate. The water agencies collectively developed an AB 3030 Plan and subsequent groundwater operating plans. As indicated in the 2015 UWMP the water agencies operate to these plans in order to avoid basin overdraft. The water entities also prepare annual water reports that describe groundwater quality and other details regarding groundwater elevations. The SCWD provides water within the City of Santa Clarita and the unincorporated area. In 2016 SCWD customers received approximately 85% imported water and 15% groundwater. The LACWD # 36 provides water to customers in Hasley Canyon and Val Verde, and in 2016 it provided only groundwater. The NCWD serves customers in the Castaic, Newhall, Pinetree, and Tesoro del Valle areas. In 2016, depending on the area served by NCWD, customers received approximately 100% imported water, 3% imported water and 97% local groundwater, or 60% imported water and 40% local groundwater. The County of Los Angeles and City of Santa Clarita coordinate on land use planning and jointly developed one general plan know as One Valley One Vision. Approximately half the SCRVES is covered by the City of Santa Clarita?s service area, and 99.9% of the SCRVES is covered by the County of Los Angeles. The remaining ~0.1% of the basin is within CLWA's service area but located in Ventura County. Via a June 12, 2017 letter, Ventura County formally declined to participate in GSA forming activities in the SCRVES. Moving forward, SGMA will require coordination of GSA activities and plans with County of Los Angeles and City of Santa Clarita planning documents. The SCV-GSA intends to manage the entire SCRVES, and a small part of the SCRVES (67 acres) that is located within Ventura County. The SCV-GSA has established a dialogue with Ventura County and together the parties will continue to coordinate with land use activities, such as those related to well permitting. Currently a moratorium exists on well permitting within this part of Ventura County.
