Jackson Retention Basin

The Jackson Retention Basin project in Indio, California, is a municipal stormwater management initiative designed to mitigate flooding at the intersection of Jackson Street and Kenner Avenue by capturing and storing runoff from storm events up to and including a 10-year, 3-hour recurrence interval. The retention basin will have a storage capacity of 1.74 acre-feet, with a bottom slope of 0.4 percent and depths ranging from 5 feet at the southern end to 5.7 feet at the northern end. A 6-foot wide, 3-inch thick Class II maintenance access path will surround the basin to ensure ongoing inspection and upkeep. To improve drainage efficiency and reduce drawdown time, a drywell will be installed to promote subsurface percolation. A new catch basin will be constructed to divert runoff currently blocked by traffic pull boxes, as the existing southern catch basin is no longer functional for this purpose. All existing site features—including trees, fences, utilities, power poles, water meters, guard posts, valves, fire hydrants, curbs, gutters, catch basins, and sidewalks—will be preserved in place during construction. The project is categorized under CEQA Guidelines §15301(f) and §15303, qualifying for a categorical exemption as a minor alteration to an existing facility and the construction of a small new structure. The place of performance is the northwest corner of Jackson Street and Kenner Avenue, Indio, CA 92201, and the City of Indio’s Public Works Department is responsible for oversight and acceptance. Donn Uyeno, Principal Civil Engineer, serves as the primary point of contact. The contract is listed as a forecast with no solicitation number, contract value, or specified period of performance, indicating it is in the planning phase and not yet awarded. There is no mention of pricing, payment terms, invoicing systems, or accounting codes. No Federal Acquisition Regulation clauses, packaging or marking requirements, evaluation factors, or standard procurement certifications are included in the documentation, nor are there details on submission procedures, proposal formats, or deadlines beyond a filing date of July 30, 2025. The absence of federal procurement structure, such as CLINs, COTR roles, FAR clauses, or socioeconomic requirements, suggests the project is being administered under local municipal authority with minimal federal oversight.
