The Ranch

The project, associated with The Ranch in Antioch, California, involves the installation of a bio-retention water quality basin and a 60-inch diameter storm drain outfall with flared end sections to manage stormwater runoff at Sand Creek. Work includes excavation of a 49-foot bank slope, placement of geotextile fabric beneath the slope, backfilling with rock to restore grade, and construction of a rock apron at the creek base to dissipate flow and prevent erosion and scour. The project is regulated under Section 1602 of the California Fish and Game Code and supported by Lake and Streambed Alteration Agreement EPIMS-CCA-53210-R3 and California Endangered Species Act Incidental Take Permit CESA No. 2081-2022-022-03, with compliance monitored through an approved Mitigation Monitoring Plan. The City of Antioch serves as the lead agency, while the California Department of Fish and Wildlife provides regulatory oversight, with Mia Bianchi and Alexis Morris as primary points of contact for environmental and planning matters. All construction activities are to occur at 6275 Deer Valley Road in Antioch, and no formal contract value, pricing structure, or federal acquisition clauses are documented, as the underlying instrument is an environmental permit rather than a procurement contract. The project aligns with CEQA requirements and regulatory conditions established to protect aquatic resources and ensure stormwater management meets environmental performance standards, but no specific delivery schedule, payment terms, or contracting officer designations are provided in the available documentation.
