Floodplain and Wetland Assessment for the Site 300 Entrance/Exit Corral Hollow Road Widening Project Adjacent to the LLNL Experimental Test Site; San Joaquin County, California

The DOE National Nuclear Security Administration (DOE/NNSA) Livermore Field Office issued a floodplain and wetland assessment for proposed traffic safety improvements to Corral Hollow Road at the entrance to the Lawrence Livermore National Laboratory (LLNL) Experimental Test Site (Site 300). The proposed road widening would encroach on the 100-year Corral Hollow Creek floodplain. In addition, a small artificial wetland occurs within the footprint of the project site.
