Two proposals for expanding shellfish production in North Humboldt Bay are currently under review by the Humboldt Bay Harbor, Recreation, and Conservation District, which is serving as Lead Agency for environmental review.

Both projects will require permits from the California Coastal Commission, Army Corps of Engineers, and Regional Water Quality Control Board. Resources agencies will also weigh in, including the California Department of Fish & Wildlife, U.S. Fish & Wildlife Service, and National Marine Fisheries Service. State and federal agencies have No Net Loss policies for eelgrass due to its importance to many species of fish and wildlife. 

Eelgrass is also thought to buffer the effects of ocean acidification, which lowers pH during upwelling events, interfering with marine organisms’ ability to form shells. Indeed, low pH of sea water has been causing major problems for oyster producers in Washington and Oregon for years.

Coast Seafoods Permit Renewal and Expansion Project: Coast Seafoods, the largest oyster grower in Humboldt Bay, is proposing to expand its footprint from 296 acres to 910 acres. The Initial Study seeks input on environmental impacts that need to be addressed in the CEQA process. Comments are due Feb. 23 Feb. 27. The Initial Study is available HERE.
 

The Mariculture Expansion Pre-Permitting Project: The Harbor District proposes to add 550 acres of production, primarily for oysters, but also for edible seaweed and Manila clams. The Draft Environmental Impact Report (DEIR) is also out for public review and comment, and is posted HERE.

A public hearing will be held on March 4 at the Harbor District conference room on Woodley Island. Written comments are due March 12.

Humboldt Baykeeper and the Northcoast Environmental Center are reviewing these proposals and will comment on the need to avoid or mitigate impacts to eelgrass, shorebirds, migratory waterfowl such as black brant, recreation, and cumulative effects of both proposed projects.
