The National Nuclear Security Administration (NNSA) Los Alamos Field Office is proposing to install a permanent fire break across the canyon bottom, which includes approximately 300 feet of the 100-year floodplain.
The proposed work will occur in Portrillo Canyon in Technical Area (TA) 36. The purpose of this work is to further reduce wildfire risk in upper Potrillo Canyon from the Lower Slobbovia firing site operations at Los Alamos National Laboratory (LANL).
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.
The Floodplain Assessment for the Proposed Fire Break at the Lower Slobbovia Firing Site at Los Alamos National Laboratory is available in the LANL Electronic Public Reading Room, on the Los Alamos Field Office NEPA Documents webpage or in hard copy at the LANL Public Reading Room, 94 Cities of Gold Road, Pojoaque, NM. The 15-day public comment period for this assessment ends March 2, 2018.
