I recently received a notice from my mortgage company stating I will need flood insurance for my recently built home. When I built the home I used FEMA' s 100 year flood map and built my home out of the flood plain so I did'nt need flood insurance. FEMA recently adjusted the floodplain on my property putting my home in the floodplain all without surveying my property or flooding. This now significantly reduces the value of my home. What right's do I have with this matter.
