Can you provide information about harmful algal blooms?
June 15, 2020How far upstream and downstream will the levees be affected and what kind of mitigation will be used? How do changes to the East Bank affect the West Bank, and what kind of mitigation will be used?
June 15, 2020The geotechnical data currently being evaluated consist of summary reports, well drilling reports and/or soil investigations by DWR (including flood projects), Caltrans and other state agencies. These data files include confidential personal information (e.g., property owner names). Due to the confidential nature of these files, most of the individual well logs and soil borings cannot be released. Soil boring data was provided for several locations in previous conceptual engineering reports for canal alignments in the eastern and western Delta and a central-Delta tunnel alignment. Soil boring data was also summarized in the following reports as part of previous studies:
- Draft Phase I Geotechnical Investigation – Geotechnical Data Report – Isolated Conveyance Facility West, 07-12-2010, DWR.
- Draft Phase I Geotechnical Investigation – Geotechnical Data Report – Isolated Conveyance Facility East, 07-12-2010, DWR.
- Draft Phase II Geotechnical Investigation – Geotechnical Data Report – Pipeline/Tunnel Option, 08-22-2011, DWR.
