Humboldt Bay Trail


The Humboldt Bay Trail is a network of paved paths connecting the communities around Humboldt Bay. Efforts are actively underway to complete a continuous 14-mile, non-motorized trail from central Arcata to the southern end of Eureka. This trail will increase road safety, provide a low-cost travel alternative, expand recreational opportunities, improve community livability, and promote active, healthy transportation. The trail is being constructed in phases by the cities of Eureka and Arcata and Humboldt County, with support from Caltrans, the North Coast Railroad Authority, California Coastal Conservancy, and many other entities. Construction funding is secured for all but the final four miles of the trail, a section called the “Humboldt Bay Trail South” Project, which extends from the Target store near Eureka Slough to the Bracut Industrial Park near Bayside Cutoff.

Partnerships For Trails

Three local agencies are currently leading the development of segments of the Humboldt Bay Trail:
  1. County of Humboldt
  2. City of Arcata
  3. City of Eureka

Humboldt County is leading the development of the Humboldt Bay Trail South segment which will provide the interconnecting link between Eureka’s and Arcata’s trail projects.

The County was allocated funds in 2015 through the State Transportation Improvement Program to complete preliminary engineering, environmental studies, and permitting and to develop engineering plans and specifications for the Bay Trail South project. Right-of-way, permits, wetland mitigation, and funding for construction still need to be secured. Preliminary cost estimates for construction range from $14 to $16 million. The goal is to have engineering plans, funding and permits in place to initiate construction by 2021.

The latest episode of KCET's California Coastal Trail series highlights the Humboldt Bay Trail and the broad community support for completing the trail. Check out this inspiring segment.

Funding to Complete the Final Four-mile Gap

In July 2018, Humboldt County applied to the state's Active Transportation Fund for $13.3 million of funding to complete the four-mile gap in the Humboldt Bay Trail between Arcata and Eureka. The total construction cost (including $2.5 million for wetland mitigation) is $18.6 million. The proposed cost-share for the project is $2 million from Coastal Conservancy and $3.3 million from Caltrans District 1. A funding decision should be made late October or November 2018

California Environmental Quality Act Document Adopted

On Tuesday, July 31, 2018, Humboldt County Board of Supervisors adopted the proposed initial study and mitigated negative declaration prepared for the Humboldt Bay Trail South project in accordance with the California Environmental Quality Act (CEQA). Humboldt County Public Works prepared the Initial Study and Proposed Mitigated Negative Declaration to analyze potentially significant environmental impacts and identify appropriate mitigation measures. The project approved by the Board includes removal of the northern group of eucalyptus trees. To provide additional information regarding the safety hazards of the eucalyptus trees, the Board asked Public Works to hire two certified arborists to perform independent risk assessments. The Board is expected to receive a report regarding the results of the risk assessments in late October or early November 2018.

The Humboldt Bay Trail Fund

The Humboldt Bay Trail Fund was established at the Humboldt Area Foundation to provide a mechanism for private donors to assist in the continued development of the Humboldt Bay Trail by focusing on the critical need for trail maintenance funds. The fund will give priority to on-going emergency trail maintenance with emphasis on supporting volunteer efforts. Make an online donation!
