Current flood maps that determine whether a homeowner's dwelling is at a risk of flooding are from the 80's and a lot has changed since then. So, FEMA is undertaking a remapping, which could change the flood risk for particular homeowners. If your home was not in a flood zone, but is in a potentially new flood zone, it might make sense for you to take precautions now and get an elevation certificate and secure flood insurance now. You could lock-in savings before insurance rates rise when the new FEMA changes are approved.
To find out more check-out the proposed changes in your community by viewing Your Community's Preliminary Flood Hazard Data and check out the publication FEMA has produced to help you understand the changes.
A few minutes of research now could prevent an insurance bill from "flooding" your savings tomorrow!
