Arroyo Bridge

The City’s environmental consultant and structural engineer are in the process of completing hydrologic studies, required by permitting agencies. The results of the studies will be used by the project team to finalize permits and construction documents.

The bridge supports and superstructure are broken at the existing stone abutment and the current repair scope includes new steel/I-beam stringers from the existing stone abutment to the North bank, as well as decking and hand railing. Construction access is challenging due to location and topography and the project includes upgrades to an existing nearby wooden bridge along the creekside trail.

The project requires multiple permits at the federal, state and city levels:

  • City of Bellingham – State Environmental Policy Act (SEPA)
  • City of Bellingham – Shoreline Development Permit Exemption (SDP, Type II)
  • Washington Department of Fish and Wildlife (WDFW) – Hydraulic Project Approval (HPA)
  • U.S. Army Corps of Engineers (USACE) – Section 404/10 Permit (Nationwide Permit (NWP) #3 – Maintenance)
  • USACE Joint Aquatic Resources Permit Application (JARPA)
  • Certification and Coastal Zone Management Act (CZMA) Consistency Determination

Please note that the project is impacted by a salmon/fish spawning window which does not allow for work to occur during certain times of the year.

In the interim, Arroyo Park and Chuckanut Mountain trails can be accessed from the North Chuckanut Mountain Trailhead parking lot on Chuckanut Drive. Bridge repairs are expected to be complete summer 2023.
