Subsurface Investigations and Laboratory Test Results by

USACE

Summary Tables of all the USACE Los Angeles District exploration activity and the corresponding laboratory test results in support of this project are presented in this attachment.

The Los Angeles District conducted the initial soils investigation between October 2014 and February 2015. The USACE investigation included twenty-six (26) hollow stem auger test borings, ten (10) sonic test holes, twenty-three (23) Becker hammer test holes: ten (10) instrumented closed bit drill, two (2) uninstrumented close bit and eleven (11) open bit drill, converting four (4) open bit Becker hammer test holes with groundwater monitoring wells, twenty four (24) test pits, and nineteen (19) Cone Penetration Test (CPT).

The Reach 9 Phase 5B Plan of Exploration, geologic contacts and profile sheets, geologic cross-sections, and all of the exploration logs are presented in Plates G 01 thru G 77. Detailed field logs for test pits were not generated since the test pits were excavated in artificial fill soils and the intent of the exploration program was to collect a representative bulk quantity of material for a soil cement study. The soil cement alternative was abandoned during the value engineering study so the soil cement study was never conducted.

A Laboratory soils testing program included classification, grain-size distribution, plasticity index, and direct shear testing of relatively undisturbed samples. Tables A-1 through A-5 below summarize all of the exploration locations and laboratory test results are presented herein.
