The proposed project would involve construction of a 12.42-mile-long road between the Whiskey Bravo Airstrip and the Korbel mining exploration area at the head of the north tributary to Portage Creek. Construction would consist of improving 2.9 miles of existing trail north of the airstrip and building 8.5 miles of new road up the Portage Creek valley. The road corridor would be 30 feet wide with a 15 foot wide driving surface. Cross drainage culverts measuring 24 inches in diameter would be installed to maintain hydrology in wetland areas and full-span timber frame bridges would be installed at 5 stream crossings. Three low water crossing locations would be established further up the watershed. Approximately 8,132 cubic yards of fill would be discharged into waters of the United States as part of the project, which would adversely impact approximately 2.55 acres of emergent, forested, and scrub shrub wetlands and 0.11 acres of intermittent and perennial stream habitat. All work would be performed in accordance with the enclosed plan (sheets 1-8), dated January of 2025.
