Chowchilla Subbasin Groundwater Recharge Project 1 (Streambed Alteration Agreement No. EPIMS-MAD-40478-R4)

The Chowchilla Subbasin Groundwater Recharge Project involves the construction of a flow diversion structure along or beneath the left bank levee of the Eastside Bypass in Madera County, California, to enhance aquifer recharge during periods of drought. The project includes the installation of a 36-inch diameter rubber gasket reinforced concrete (RGRCP) conveyance pipeline, a 14-foot diameter fish screen, a concrete cutoff wall, a reinforced concrete control box, and a reinforced concrete pump box, all designed to safely divert surface water into the subsurface. The effort is statutorily exempt from California Environmental Quality Act (CEQA) review under Executive Order N-7-22 due to the ongoing drought emergency and qualifies for exemption under Public Resources Code Section 21080(b)(4) and CEQA Title 14, Section 15269(c). The project is sited at three locations near Chowchilla—Haynes Parcel, Clayton Flood-MAR, and Vlot Parcel—each situated approximately 14 miles southwest of the city, with final construction activities occurring in the vicinity of Lincoln Road, Avenue 20, Avenue 21, and Road 3. The Central Valley Flood Protection Board is the approving agency, with Madera County serving as the lead agency and primary point of local administration. There is no formal contract value, pricing structure, or CLIN/SLIN data provided, indicating this is a preliminary or emergency-driven action not yet structured with standardized federal financial terms. The solicitation number is 19789, linked to the Streambed Alteration Agreement EPIMS-MAD-40478-R4, with a posting date of December 19, 2025, and an execution date of December 17, 2025. No federal acquisition regulation (FAR) clauses, federal contracting requirements, or socioeconomic certifications apply; the initiative operates under state authority without inclusion of federal procurement mechanisms such as WAWF invoicing, COR/COTR designations, TAS accounting codes, or UEI/CAGE identifiers. Performance will occur entirely within Madera County, with inspection and acceptance responsibilities held by state and county agencies, not by a formal contracting officer or technical representative. No delivery schedule, FOB terms, or submission deadline are explicitly defined, and proposals are to be filed with the Office of Land Use and Climate Innovation in Sacramento, though no formal bid process or evaluation criteria are documented.
