Gravel Extraction on the Lower Mad River

The project involves commercial gravel extraction from the Mad River at the Guynup site in Humboldt County, California, under a single encroachment permit with an annual extraction limit of 33,600 cubic yards, as determined by a flow-based replenishment analysis designed to ensure sustainable resource use and address prior over-extraction concerns. Historical data from 2020 through 2024 shows annual extraction volumes of 17,036; 18,580; 14,867; 27,144; and 35,172 cubic yards, with the 2024 figure exceeding the current permitted limit, indicating a potential need for regulatory review. Extraction activities are governed by federal permit conditions and must comply with the California Environmental Quality Act, including implementation of approved mitigation measures, payment of environmental filing fees under Fish and Game Code § 711.4, and adherence to determinations issued by the California Department of Fish and Wildlife as the lead agency. The project is administered through the Humboldt County Planning and Building Department and monitored by CDFW staff, with no formal federal contract clauses, pricing data, payment details, invoicing systems, or procurement evaluation factors documented, indicating the arrangement is primarily a regulatory environmental permit rather than a federally procured contract. Performance occurs at the specified parcel locations in the Mad River channel, and all operations are subject to ongoing environmental compliance oversight without defined contract term dates, delivery schedules, or financial terms beyond regulatory limits.
