Timmerman Jct. to Ketchum Wetland Mitigation

Project: Boulder Flats Wetland Mitigation
Project No.: A011(624)
Key No.: 11624

Project Background

Within the Timmerman to Ketchum corridor are several environmental impacts that require a mitigation plan. Pursuant to the Final Environmental Impact Statement (FEIS) for the reconstruction of Idaho 75 Timmerman to Ketchum, ITD is required to develop a wetland mitigation plan to create and offset all wetland impacts from the reconstruction of Idaho 75 throughout the corridor.

The original site selected to facilitate mitigation at Boulder Flats (milepost 139-140.5) would have realigned Idaho 75 and recreated natural wetlands. Through the wetland delineation, engineering studies, and roadway design for the Boulder Flats site, it was determined the site was not viable due to substantial destruction of additional wetland area to recreate new mitigation wetlands.

Project Description

ITD remains committed to fulfill its obligation to develop wetland mitigation for the Idaho 75 Timmerman to Ketchum corridor. ITD has purchased credits in an approved wetland bank of sufficient size to satisfy the mitigation obligation.

The wetland bank, developed by The Wetland Group of Eagle, Idaho, is located at Grove Creek near U.S. 20 southeast of Bellevue.

Development of a wetland mitigation plan did include a cooperative effort from the U.S. Army Corp of Engineers, U.S. Environmental Protection Agency, Federal Highways Administration, and other key agencies and stakeholders.
