The project is limited to one (1) encroachment (Table 1) for an existing stream. crossing. The project will include excavation, removal of two undersized culverts, replacement with new properly sized bridge, back filling and compaction of fill, and rock armoring as necessary to minimize erosion. The project will also involve
the restoration of the stream channel, and the installation of grade control structures in order to prevent erosion. A detailed engineering design plan for the bridge will be provided to CDFW for approval prior to any construction activities
see paper for more details.
The project to be completed is located within the South Fork Smith River watershed,
approximately 16 miles east southeast of Crescent City, County of Del Norte, State of California. The project is located in Section 24, Township 15N, Range 2E, Humboldt Base and Meridian; in the Canthook Mountain U.S. Geological Survey 7.5-minute quadrangle; Assessor's Parcel Number 126-180-27; latitude 41.680316 N and longitude -123.896685 W at the stream crossing.

Class 1 CCR, title 14, 15301, 15303, 15333
Reasons for Exemption
The project replaces failing culverts with _an appropriately sized and placed
bridge structure. The project implements stream bank stabilization with native vegetation or other bioengineering techniques, the primary purpose of which is to reduce or eliminate erosion and sedimentation. There would be no significant adverse impact on endangered, rare or threatened species or their habitat pursuant to section 15065. There are no hazardous materials at or around the project site that may be disturbed or removed. The project would not constitute an expansion of use.
