Humboldt Bay Trail


The Humboldt Bay Trail is envisioned as a network of trails providing non-motorized access for transportation and recreational use throughout the Humboldt Bay region.  The current focus is on developing a continuous trail from central Arcata to south Eureka over the next several years for a total length of approximately 13 miles.  The Humboldt Bay Trail is being developed as a collaborative effort between the Humboldt County Association of Governments, Humboldt County, City of Arcata, City of Eureka, California Department of Transportation (Caltrans), State Coastal Conservancy, North Coast Railroad Authority (NCRA), and a variety of other agencies and organizations.

The portion of the Humboldt Bay Trail between Eureka and Arcata is proposed to be situated within the U.S. Highway 101 and railroad transportation corridors. This portion is being developed in conjunction with the Highway 101 Eureka-Arcata Corridor Improvement Project, which will improve highway safety and operations at six at-grade intersections.

The Humboldt Bay Trail Project Update brochure was produced in June of 2014 to provide details about project history, goals, and status.

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 project area extends from the Bracut Industrial Center to X Street in Eureka near the Target store, for a total length of 3.8 miles.

The County was allocated funds 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 segment.  This work has been initiated and is expected to require two to three years to address the various challenges and constraints.  Preliminary cost estimates for right-of-way and construction range from $9 to $12 million. Costs for environmental mitigation are estimated at $1.5 to $2.0 million.  Future funding will need to be secured for these components.

Project Documents

Request for Qualifications Questions & Answers
(December 10, 2015) – This memo provides answers to questions received during the RFQ solicitation period.

Request for Qualifications (November 18, 2015) – This RFQ solicits Statements of Qualifications from experienced and qualified engineering consulting firms to provide professional services to assist with planning, environmental analysis, permitting, and engineering design for the Bay Trail South segment of the Humboldt Bay Trail.  Submittal deadline is December 18, 2015.

Preliminary Surveying Analysis of Railroad Right-of-way, Northwestern Pacific Railroad Co., Eureka to Arcata (around Humboldt Bay) (February 26, 2015) - This report contains the results of an analysis of deeds associated with the right-of-way of a portion of the Northwestern Pacific Railroad around Humboldt Bay between Eureka and Arcata. The purpose of the study was to develop a master list of deeds that define the railroad right-of-way within the project area, and to identify the location and extent of the parcels referenced in the deeds.  This file contains the report text, figures, and tables (no attachments).

Botanical Report (September 17, 2014) - This report documents the results of a survey for special status plants within the project area.

Initial Engineering Study (August 2014) - This report provides a detailed evaluation of alignment options within the project area.  Alignment options generally include “rail-with-trail” (trail closer to the railroad) and “highway-with-trail” (trail closer to the highway) segments.  The Initial Engineering Study is a technical support document and does not identify a preferred or recommended alignment.  

Project Study Report (March 18, 2014) - This report provides a general overview of the project including background and history, purpose and need, planning and design issues, and alternatives.
