Prado Basin Ecosystem Restoration and Water Conservation Integrated Feasibility Study, Orange County, CA

The California Department of Fish and Wildlife issued Lake and Streambed Alteration Agreement EPIMS-RIV-52599-R6 to the Orange County Water District to authorize maintenance activities at the Prado Constructed Wetlands located in the Prado Basin along the Santa Ana River in Riverside County, California. The agreement, approved on January 20, 2026, permits a range of operational and conservation activities including erosion repairs, reconstruction of existing facilities, removal of trash and sediment, repairs to water conveyance structures, vegetation management, and the use of a temporary push-up dam to divert water during work. These activities are conducted under the authority of Section 1602 of the California Fish and Game Code and are subject to compliance with the California Environmental Quality Act, though no Mitigation Reporting and Monitoring Plan or Statement of Overriding Considerations was adopted. The project does not involve a traditional procurement contract with pricing, line items, or payment terms; instead, it functions as a regulatory permit with enforcement and acceptance responsibilities held by CDFW. The Orange County Water District serves as the lead agency responsible for execution, while CDFW maintains oversight and approval authority, with Lisa Cardoso as the environmental scientist contact and Shawn Nevill as the principal planner and primary point of contact. No federal contract clauses, FAR provisions, packaging standards, or evaluation factors apply, as this is a state environmental permitting instrument focused solely on ecological and hydrological maintenance within a regulated aquatic environment.
