NARRATIVE DESCRIPTION OF GSA AUTHORITY TO MANAGE TEMESCAL SUBBASIN The City of Corona (Corona), the City of Norco (Norco), and the Home Gardens County Water District (Home Gardens) have developed and adopted a Memorandum of Understanding (MOU) for the purpose of forming a Groundwater Sustainability Agency (GSA) for the entirety of the Temescal Subbasin of the Upper Santa Ana Valley Groundwater Basin (Bulletin 118 Basin 8-002.9) in accordance with the Sustainable Groundwater Management Act (SGMA). Corona, Norco, and Home Gardens have long relied on groundwater from the Temescal Subbasin for municipal use, and these agencies have also been responsible for managing groundwater conditions in the Temescal Subbasin for decades. Corona adopted a Groundwater Management Plan (GWMP) in 2008 that covers the Temescal Subbasin. Corona, Norco, and Home Gardens service areas cover almost all of the Temescal Subbasin. Those portions of the subbasin outside of these service areas are not within the area of any other proposed GSA. While the service areas of Corona, Norco, and Home Gardens do not cover the entire subbasin, these agencies do propose to serve as the GSA for the entire subbasin. The three agencies in the GSA are coordinating with Riverside County Flood Control and Water Conservation District (RCFCWCD) for these currently unmanaged areas. Specifically, the RCFCWCD recognized the ongoing efforts for this GSA and offered to participate in any advisory or stakeholder committee formed by the GSA. Details of the MOU, including the resolutions adopting the MOU and bylaws are attached to this submittal.

NARRATIVE DESCRIPTION OF GSA AUTHORITY TO MANAGE TEMESCAL SUBBASIN The City of Corona (Corona), the City of Norco (Norco), and the Home Gardens County Water District (Home Gardens) have developed and adopted a Memorandum of Understanding (MOU) for the purpose of forming a Groundwater Sustainability Agency (GSA) for the entirety of the Temescal Subbasin of the Upper Santa Ana Valley Groundwater Basin (Bulletin 118 Basin 8-002.9) in accordance with the Sustainable Groundwater Management Act (SGMA). Groundwater has been an important component of water supply in the Temescal Subbasin for more than 100 years. Until the 1970s, most of the groundwater production in the subbasin was for agricultural supply (Todd and AKM, 2008). A few well owners have also produced small amounts of groundwater for domestic use (Todd and AKM, 2008). Production for municipal supply increased in the 1960s and 1970s and continues today. Corona, Norco, and Home Gardens have long relied on groundwater from the Temescal Subbasin for municipal use, and these agencies have also been responsible for managing groundwater conditions in the Temescal Subbasin for decades. Corona adopted a Groundwater Management Plan (GWMP) in 2008 that covers the Temescal Subbasin. Corona, Norco, and Home Gardens service areas cover almost all of the Temescal Subbasin. Those portions of the subbasin outside of these service areas are not within the area of any other proposed GSA. While the service areas of Corona, Norco, and Home Gardens do not cover the entire subbasin, these agencies do propose to serve as the GSA for the entire subbasin. The three agencies in the GSA are coordinating with Riverside County Flood Control and Water Conservation District (RCFCWCD) for these currently unmanaged areas. Specifically, the RCFCWCD recognized the ongoing efforts to for this GSA and offered to participate in any advisory or stakeholder committee formed by the GSA.
