Jackson Retention Basin

The City of Indio is forecasting a civil infrastructure project to construct the Jackson Retention Basin at the northwest corner of Jackson Street and Kenner Avenue in Indio, California. The project aims to mitigate street flooding caused by a blocked drainage pipe and provide a discharge location for the Indio Water Authority's Well BB flush system. The basin will feature a storage volume of 1.74 acre-feet to accommodate a 10-year, 3-hour storm event, a basin bottom depth ranging from 5 to 5.7 feet with a 0.4 percent slope, and a drywell to enhance percolation and reduce drawdown time. Additional construction includes a new catch basin to handle runoff from the Jackson Street and Kenner Avenue intersection and a 6-foot wide, 3-inch thick Class II maintenance access path. The project is categorized as a forecast under NAICS code 237990 and is managed by the City of Indio Public Works Department, with Principal Civil Engineer Donn Uyeno serving as the primary point of contact. It is categorically exempt from the California Environmental Quality Act under Guidelines 15301(f) and 15303, as it involves minor alterations and the construction of small drainage structures. All existing site infrastructure, including utilities, trees, and fire hydrants, must be protected in place. No specific contract value, performance period, or federal acquisition regulation clauses have been established, as the current documentation serves as a project forecast and environmental notice of exemption.
