Floodplain Permitting Process
Communities that participate in the NFIP are also responsible for enforcing their floodplain regulations through a permitting process. Guidance and information on the floodplain permit process can be found on the Permit Process, Applications and Certificates page.
Floodplain Regulations that Exceed the Minimum NFIP Regulations
OSI and FEMA highly recommend that communities adopt regulations that exceed the minimum regulations. The minimum regulations do not account for the effects that floodplain development will have on future flood levels.
OSI has compiled a list of communities around the state that enforces at least one regulation that exceeds the minimum NFIP regulations. The list also includes a link to the community's ordinance online, when available. If your community is not listed and you would like to be added, please Contact Us.
