What is a floodplain?
Last Updated: April 18, 2018
The City of Mount Holly has participated in the National Flood Insurance Program since 1974. As part of the participation requirements, the City must adopt floodplain regulations and Flood Insurance Rate Maps (FIRM's), as noted in Article XVI of the Zoning Ordinance. The most recognized floodplain is the 100-year floodplain, representing a flood event occurring every one hundred years or a flood event that has a 1% probability of occurring in any given year.
