Mill Creek Canyon Road

FHWA-CFLHD, in cooperation with Salt Lake County, Millcreek, and the Uinta-Wasatch-Cache National Forest (UWCNF) are proposing improvements to the upper 4.6 miles of Mill Creek Canyon Road, located primarily within the UWCNF in Salt Lake County, Utah. The purpose of the project is to improve user safety, access to recreational opportunities for all users, and water quality degraded by surface erosion and poor drainage infrastructure. The project would extend from the Winter Gate parking area to the Upper Big Water Trailhead, where the road terminates. Funding for the project is through the Federal Lands Access Program in conjunction with a local funding match.

FHWA-CFLHD, as the lead agency, has examined actions to improve access and safety for visitors to upper Mill Creek Canyon and determined that the Upper Mill Creek Canyon Road Improvement Project will have no significant impact on the human or natural environment. The Finding of No Significant Impact (FONSI) documents FHWA-CFLHD’s decision on the project under the National Environmental Policy Act (42 U.S.C. §4321 et seq. and 40 C.F.R. §1501.6) and FHWA’s implementing regulations (23 C.F.R. §771, specifically 23 C.F.R. §771.121). It incorporates by reference the Environmental Assessment and Draft Section 4(f) Evaluation for the Upper Mill Creek Canyon Road Improvement Project (EA) and presents relevant information to support FHWA-CFLHD’s decision on the project.

The Forest Service will issue an independent decision on limited aspects of the project, as described in, and based on the analysis in the FHWA-CFLHD EA. The Forest Service decision is subject to 36 CFR 218 subparts A and B.
