Humboldt County 4th Street Property Acquisition and Development Project
Humboldt County retained LACO Associates to prepare an Initial Study and Mitigated Negative Declaration of environmental impact for the Humboldt County 4th Street Property Acquisition and Development Project in accordance with the California Environmental Quality Act (CEQA). The proposed project would acquire three parcels located in Eureka: Assessor Parcel No. (APN) 001-174-006 (1033 and 1039 Fourth Street), APN 001-174-007 (1023 and 1025 Fourth Street), and APN 001-174-008 (1017 Fourth Street). These parcels are located adjacent to a County-owned parcel (APN 001-174-009) containing the Public Defender’s (PD) and Child Abuse Services Team (CAST) offices. The proposed project involves purchase of land, demolishing all or a portion of the existing buildings currently located on site, and redevelopment of the site. Five potential development scenarios are currently under consideration, including:
- Removing the newly-acquired buildings and turning their footprint into parking with landscaping, while leaving the existing PD and CAST offices and parking in place.
- Turning the entire site into parking with landscaping.
- Removing all existing buildings and replacing with three modular buildings, parking, and landscaping.
- Constructing an approximately 110,000 square foot building to be used for the Humboldt County Administrative Complex (HCAC). At this time, it is estimated that the proposed HCAC building would have five or six levels and a maximum height of 100 feet.
- A combination of Development Scenarios #1 and 4, where a phased approach would occur. In the first phase, the PD/CAST offices and parking would remain, the other buildings on-site would be demolished, and a 35-space parking lot on the footprint of the demolished structures would be constructed. Phase 2 would involve construction of the HCAC facility.

ACV Airport Microgrid Project
Humboldt County Public Works prepared an Initial Study and Mitigated Negative Declaration Opens a New Window. 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.
