Permit No. 11540-1 – Existing Pump, Well, and Pipeline Upgrades Project

The project authorizes the continued use and minor upgrades of existing infrastructure associated with a six-inch steel irrigation pipe originally permitted under Permit Nos. 11540 and 11540-A, issued in 1976 to Wilearlee Walnuts. These include a power pole, well, pump, three sand media filters, and a footing pad, all of which are authorized for ongoing operation without expansion of their current use. The permit also allows for the construction of a timber-framed shade structure and the installation of up to six raptor perches and barn owl boxes, designed to enhance local wildlife habitat. All work is limited to maintenance, minor modifications, and ecological enhancement, with no increase in facility capacity or operational footprint. The project is located on the left bank levee of the Sacramento River in Colusa County, California, approximately twelve miles north of the city of Colusa along River Road. The permitting process is governed by the California Environmental Quality Act (CEQA), with categorical exemptions under Sections 15301 for existing facilities and 15303 for new small structures applied, meaning no full environmental impact report is required. The Central Valley Flood Protection Board is the approving agency, with Westervelt Ecological Services serving as the lead entity responsible for implementation. Key contacts include Jordan Robbins, Senior Environmental Scientist at the Board, and Dayna Winchell, Senior Conservation Planner at Westervelt. No federal acquisition regulation clauses, pricing data, payment terms, inspection standards, or contractor certifications are included in the documentation, as this is a state-level environmental permit rather than a federal procurement contract. The posted date is December 8, 2025, and the signing date of the underlying exemption notice is December 5, 2025, with no specified period of performance or delivery schedule outlined. There is no solicitation number, contract value, or formal offeror submission process detailed, indicating this is a permitting action rather than a competitive or negotiated contract award.
