Document Description
The planned work includes overwater and land-based soil borings, cone penetration tests, and geophysical surveys. The primary objective of the proposed project is to determine the composition, location, and geotechnical properties of soil materials commonly found in the Delta which would inform the design, environmental analysis, and development of alternatives for a potential Delta conveyance project and contribute to DWR's overall understanding of Delta geology. Based on current engineering considerations of alternative alignments for the proposed Delta Conveyance Project, the following additional geotechnical information is needed for preliminary design and to support environmental review. The proposed changes include the removal of 60 soil investigation sites identified in the 2020 Final IS/MND and the replacement with 60 new soil investigation sites in locations that are in and around the general study area of the Approved Project but were not specifically, previously evaluated in the 2020 Final IS/MND
