SPA 124 Permit Decision Notice: Dorvall Corner Bank Repairs and Stabilization
Mar 17, 2025 2:30 PM
Carbon County is planning repairs to a previous bank armoring project on Dorvall Corner on the Edgar Fromberg Road along the Clarks Fork of the Yellowstone River. The original project was done to prevent further bank erosion after the 2022 flood event along a section of river directly adjacent to the Edgar Fromberg Road. Bank stabilization efforts consisted of placing rock-filled gabion mattresses. However, high flows in the spring 2024 (25-year flood event) damaged the gabion mattresses and fill material was transported downstream. Currently, the bank is at risk for additional erosion. The proposed project entails refilling the gabion mattresses with large angular rock rather than the previous round river rock.
Based on the environmental review provided in the Draft EA, and, to the greatest extent possible, in accordance with all applicable laws, rules, regulations, and policies, FWP determined the proposed action (Alternative 2), will not have significant adverse impacts on the human environment associated with the proposed action and constitutes a reasonable and appropriate strategy to achieve identified objectives. Therefore, preparation of an environmental impact statement or EIS is unnecessary.
FWP hereby adopts the Draft EA as final and approves Alternative 2, the Proposed Action.
