Buckhorn Closure - Geotechnical Studies - Phase 1
NOE - Notice of Exemption
Caltrans proposes to conduct seismic refraction studies from PM 0.75 to 2.5, on (SR) 299 in Shasta County. These geotechnical studies will measure sound waves on geological layers and rock/soil units in order to characterize the subsurface geologic conditions and geologic structure. The work will require brush and duff clearing five feet wide and up to a height of nine feet, laying electric cable and geophones on the ground, and transmitting seismic shock waves through the ground. The seismic shock will be provided by on e of the following methods: a hammer and metal plate; a blank shotgun shell placed down a hole, 2 to 3 feet in depth (2 inches in diameter; or a small amount of anfo explosive placed in a similar hole. These proposed studies are to be conducted in the summer and fall of 2011.
This project will not result in any significant impact to the environment.
