Los Alamos National Laboratory Floodplain Assessment for the West Road Post and Cable Fencing Project

The National Nuclear Security Administration (NNSA), a semi-autonomous agency within the U.S. Department of Energy (DOE), is proposing to take action at Los Alamos National Laboratory (LANL) to install post and cable or in-kind barriers along West Road at selected locations near the Los Alamos County ice-skating rink in Los Alamos Canyon. The proposed project is intended to improve vehicular and pedestrian safety on West Road by reducing traffic hazards associated with unsafe roadside parking and reduce wildland fire hazards associated with vehicles driving and parking on vegetation. West Road crosses approximately 0.35 miles (mi.) (1,900 feet (ft.)) of the Los Alamos Canyon floodplain at the bottom of Los Alamos Canyon. Project activities within the floodplain include blocking access to the informal roadside parking along either side of West Road in Los Alamos Canyon.
