CVFPP Conservation Strategy Appendix I. Floodplain Restoration Opportunity Analysis

As part of the Conservation Strategy for the 2017 Central Valley Flood Protection Plan (CVFPP), a continuation of the Floodplain Restoration Opportunity Analysis (FROA) (DWR 2012a) was conducted to develop, identify, and prioritize potential locations for implementing management actions. Two types of management actions were considered in this analysis: modification of floodplain topography (specifically, lowering floodplain topography through targeted excavation) and levee relocation (specifically, constructing setback levees). Preliminary areas for floodplain modification and setback levees were identified within the Systemwide Planning Area (SPA) of the State Plan of Flood Control (SPFC) (Figure 1-1). The following technical memorandum documents the goal, objectives, methods, and results of this analysis.
