Purpose of the RFMPBuild upon the CVFPP by describing
regional flood management challenges and deficiencies, identifying solution
strategies and projects, setting priorities, and developing a local financing plan for their implementation which leverages
local, State, and federal funding opportunities.

Levees: Raise crown elevation Increase levee cross section and improve its geometry Provide stability berms buttress the levees Provide waterside berms and erosion protection on the water side Provide cutoff walls, seepage berms, or relief wells Reconstruct deficient levees in place or construct levee setbacks Provide off‐stream transitory storage Provide improved access and visibility to facilitate inspection and
flood fighting activities Remove or improve levee penetrations Provide overflow protection Provide vegetation management including root barriers
