NNSA News:

The National Nuclear Security Administration (NNSA) has published the floodplain statement of findings for the proposed construction of an additional vehicle inspection lane at the guard post near the East Jemez Road and N.M. 4 intersection.

The project is intended to provide expedited inspection times for vehicles transporting time sensitive loads, such as concrete and asphalt to Los Alamos National Laboratory. Project activities within the 100-year floodplain would include construction of an expedited vehicle inspection lane, relocation of a 4-strand wire fence, possible relocation of at least one power pole, and a laydown area.

A floodplain assessment evaluated potential impacts to floodplain values and functions from implementation of the proposed action, identified alternatives to the Proposed Action, and allowed for meaningful public comment.

It was determined the proposed project would result in limited and minor direct and indirect impacts to the Sandia Canyon 100-year floodplain and would not result in adverse impacts to the floodplain values or functions. Temporary disturbance within the floodplain would cease following completion of installation activities. Best management practices would be implemented.

This proposed project would not significantly modify flow paths within the floodplain from pre-project conditions to post project conditions. No effects to lives and property associated with floodplain modifications are anticipated.
