Document Description
The project is limited to one encroachment for commercial gravel extraction from a single gravel bar on the Middle Fork of the Eel River. On May 19, 2022, the County of Mendocino granted approval of Major Use Permit and Reclamation Plan U_2020-0007/REC-2020-0001 – 51110 Covelo LLC. Consistent with those parameters set forth in the County permit, the Permittee proposes to extract up to 20,000 cubic yards of gravel, rock, and sand annually from the Stewart Bar on the Middle Fork Eel River. Gravel extraction at the site will be consistent with accepted skimming methodology which involves removal of gravel from selected areas of the bar in a sloped configuration to avoid creating holes or channels, and is done by using excavators, loaders, and haul trucks. Extraction will be limited to the aggraded portion of the bar, with horizontal and vertical offsets for buffers from the low-flow channel. Total annual extraction volumes would be replenishment based, with a maximum annual quantity of 20,000 cubic yards. Actual extraction quantities shall be determined on an annual basis based on channel morphology and gravel replenishment, subject to review and approval by CDFW and the National Marine Fisheries Service (NMFS). During operations, water will be drafted from the Middle Fork Eel River adjacent to the gravel bar for use as dust control only. The drafting will be limited to a maximum of 8,000 gallons/day (two loads) and the maximum instantaneous diversion rate will not exceed 100 gallons per minute. Intake screens will meet CDFW/NMFS fish screen requirements. Temporary crossings may be necessary. The location, design, and timing of installation and removal of crossings will be subject to review and approval by the gravel extraction review agencies. Post-extraction reclamation activities will include removal of any remaining temporary gravel stockpiles, finished grading of the gravel bar utilizing native materials to fill in low areas and depressions, re-contouring of the gravel bar to meet agency-approved post extraction slopes and gravel bar configuration, removal of temporary crossings, installation of storm water control measures, and removal of all work materials and debris.
