The National Nuclear Security Administration (NNSA) Los Alamos Field Office is proposing to allow Los Alamos County to replace an irreparably damaged water line from the Los Alamos Canyon Reservoir to the townsite of Los Alamos.
This activity would occur on small segments of land within the Los Alamos County 100-year floodplain. The majority of this project occurs on property owned by the U.S. Forest Service. A segment of this project occurs on U.S. Department of Energy (DOE) administered land in Technical Area (TA) 62.
In accordance with 10 Code of Federal Regulations 1022 Compliance with Floodplain and Wetland Environmental Review Requirements, NNSA has prepared a floodplain assessment for the proposed action.
