Arcata Annie & Mary Trail Connectivity Project

The Arcata Annie and Mary Trail Connectivity Project in Humboldt County, California, involves the construction of approximately 3.5 miles of Class I multi-use trail designed for recreational access and non-motorized transportation. The scope of work specifically focuses on two encroachments within the Mad River watershed. The first encroachment requires the installation of a 40-foot bridge spanning an unnamed tributary to the Mad River, and the second involves upgrading an existing culvert. Technical requirements for these sites include work site isolation, excavation, the removal of the old culvert, installation of a properly sized replacement, backfilling, compaction of fill, and the application of rock slope protection and armoring to prevent erosion. The project is managed by the Humboldt County Department of Planning and Building and the Department of Fish and Wildlife Northern Region, falling under NAICS code 237310. It is governed by Lake or Streambed Alteration Agreement EPIMS-HUM-58972-R1C and complies with the California Environmental Quality Act and Public Resources Code section 21108. A Notice of Determination has confirmed that the project will not have a significant environmental effect. Performance is centered in Arcata, California, with specific coordinates identified for both the bridge and culvert installation sites.
