Preliminary Engineering Studies for Overwater and Land Geotechnical Exploration

Preliminary Engineering Studies for Overwater and Land Geotechnical Exploration

The DWR is planning to conduct overwater and land geotechnical borings, perform cone penetrations tests (CPT) and dig ~30 small test pit in order to test soils in the Sacramento-San Joaquin Delta. This testing is necessary because of the lack of geotechnical data available to DWR in the relevant area. DWR's geotechnical staff and/or its consultants will investigate the engineering properties of the soils in the Delta, including auxiliary structures, as well as the proposed intakes and the proposed forebays. The purpose of the investigation is to gather necessary geotechnical information to support the preparation of a Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the proposed BDCP and/or preliminary engineering design for the Delta Habitat Conservation and Conveyance Program.
