Natural Resources


Natural Resources staff perform environmental review and permitting for Public Works projects and operations, to support Humboldt County’s commitment to environmental stewardship and appropriate resource management.

The office manages environmental regulatory compliance and coordinates with Public Works management and staff on environmental practices and resource management involving county roads, bridges, airports, buildings, parks, levees, gravel mining and quarry rock extraction, solid waste facilities, and county-managed natural areas and open space.

Natural Resources staff work with engineering and maintenance staff to incorporate environmental constraints and considerations into planning and design.  The office prepares environmental review documents required by federal and state funding agencies; directs and administers specialized technical studies to assess potential environmental impacts; identifies measures to avoid and minimize impacts; develops feasible mitigation measures; and supports the environmental permitting process.

The office manages the closed municipal landfill at Table Bluff and environmental aspects of the County’s franchise solid waste facilities (Redway Transfer Station and 11 container sites).  The Table Bluff landfill is equipped with a leachate collection and treatment system.

ACV Airport Microgrid Project


Humboldt County Public Works prepared an Initial Study and Mitigated Negative Declaration of environmental impact for the ACV Airport Microgrid Project in accordance with the California Environmental Quality Act (CEQA). The proposed project would construct a 2.3 megawatt microgrid facility on approximately nine acres at the California Redwood Coast-Humboldt County Airport. The facility would include photovoltaic arrays and a lithium-ion battery energy storage system. Four mitigation measures were identified to ensure that environmental impacts are less than significant. The public review period for the CEQA document ended April 30, 2018. The Board of Supervisors adopted the CEQA document on May 8, 2018. Construction is expected to begin in 2020.
