Slope Stabilization at MacArthur Air Force Base

Lakeshore Toltest subcontracted ICS to remediate a ¼ mile soil slope separating Fort MacArthur AFB from adjacent Port of Los Angeles property. Construction included removal of all vegetative material, excavation of all loose/unstable soil within the native soil portion of the wall, mass excavation/removal of impacted “end‐dump soil” that had been installed as a temporary soil buttress, and installation of a soil nail wall with reinforced structural steel and shotcrete. In addition to remedial grading activities and excavation, ICS transported and disposed (T&D) of over 20,000 cubic yards of impacted soil. Although ICS was working off of construction drawings, the final subgrade locations were unknown. To address this challenge, ICS worked closely with the geologist on record to identify these limits so the project could be built according to the specifications provided.
