The geotechnical data currently being evaluated consist of project-specific data collected over the past years by DWR, supplemented by historic data from other agencies. The project data has been compiled and issued as part of the administrative record for prior environmental permitting for the California WaterFix project. The majority of the supplemental agency data are publicly available through Caltrans and the California State Water Resources Control Board. Water well data compiled by DWR is confidential and therefore cannot be shared. There are other limited data provided by specific agencies that are also subject to confidentiality requirements and therefore cannot be shared.
