Los Alamos County Waterline and San Ildefonso Pueblo Fiber Optic Cable Floodplain Assessment
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) for two projects by two separate proponents in Los Alamos County (County), New Mexico (NM). One project is the construction and operation of a new water supply line within the right-of-way of New Mexico State Highway 4 (NM 4) by Los Alamos County’s Department of Public Utilities (LACDPU). The other project is the installation of a fiber optic conduit and cable within the right-of-way of NM 4 and NM Highway 502 (NM 502) by Pueblo de San Ildefonso (Pueblo).
