Document Description
A tunnel through the ANF is being considered for a portion of the Palmdale to Burbank Section for the California High-Speed Rail Project. Previously, five original sites had been elected to investigate in-situ rock conditions and to measure groundwater pressures along proposed tunnel alternatives. Since then, three alternate site locations have been identified. Alt-B1, Alt-B2 and Alt-B3. These test borings are needed to test site conditions in locations that lie close to the alternate alignments proposed by the California High-Speed Rail Authority. The purpose of the geophysical investigation is to obtain sufficient subsurface field data to help evaluate the tunnel portion of alternatives with respect to potential environmental impacts (i.e., groundwater, hydrogeological and surface water resources), design constraints, and construction constraints.
