What are the requirements for additions or improvements to structures?
Any repair, reconstruction or improvement to a structure, the cost of which equals or exceeds fifty (50) percent of the fair market value of the structure requires a Floodplain Development Permit. Any addition, no matter what the cost, will also require a Floodplain Development Permit. All other conditions apply.
