2 InformationPhase 2 Information
Knowledge gained from the Phase 1 Risk Analysis Report (URS/JBA 2008h) was used to develop improvement strategies in the Phase 2 report that would increase the reliability of the Delta and Suisun Marsh levees that present the highest risks. The objectives of the DRMS Phase 2 report were to evaluate the risks and consequences to the State and the Delta associated with the failure of Delta levees considering their exposure to all hazards (seismic, flood, subsidence, seepage, sea-level rise) under present and foreseeable future conditions.
