homeowner options after a flood
Move to a new home
Usually expensive, may need to leave your neighborhood, value of your (flooded) house significantly lower than pre-flood.
Elevation
Guaranteed protection if elevate high enough....but very expensive, intrusive, and inconvenient. ROI (return on your investment) questionable at best.
Use permanent or temporary flood barriers
None are well-suited for residential use--were developed for commercial applications.
