RIGBY, Idaho –
The U.S. Army Corps of Engineers’ Walla Walla District issued a Finding of No Significant Impact (FONSI) on June 29, 2018, to repair several sections of the Heise-Roberts Levee System along the Snake River in Jefferson and Madison counties, Idaho. The levees were damaged by sustained high flows during the 2017 and 2018 flood seasons.
The Corps of Engineers has authority under Public Law 84-99 to supplement local efforts in the repair of both federal (Corps-constructed, locally operated and maintained) and non-federal (constructed by non-federal interests or by the Work Projects Administration) flood risk management projects damaged by flooding events. Several criteria must be met to satisfy eligibility for flood rehabilitation assistance, including participation in the National Levee Safety Program and complying with maintenance standards.
As a federally constructed levee system, locally maintained to acceptable standards under the National Levee Safety Program, the Heise-Roberts Levee System is eligible for rehabilitation assistance from the Corps.
The Corps prepared an environmental assessment (EA) for this rehabilitation project to repair the levee to its pre-flood-damage condition. The Corps’ signed FONSI, EA and other associated attachments are available for viewing or downloading on the Walla Walla District’s website www.nww.usace.army.mil/Missions/Environmental-Compliance.For more information about the Corps’ PL 84-99 programs, visit the District’s Flood Assistance webpage www.nww.usace.army.mil/Missions/Flood-Assistance.
