Document Description
A tunnel through the ANF is being considered for a portion of the Palmdale to Burbank Section of the California High Speed Rail Project. The purpose of the geophysical investigation is to obtain subsurface field data to help evaluate the tunnel portion of alternatives with respect to potential environmental impacts, design constraints, and construction constraints.
The project consists of data collection and resource evaluation activities that would not result in major disturbance to environmental resources because all data collection and evaluation activities would be generally in existing disturbed areas and would be temporary in duration; as such, no permanent effects would occur. Temporary effects may occur as a result of the subsurface investigation; but would not be significant because the impacts are in existing disturbed areas and any new disturbance would be restored once investigations are complete.
