Information about a community's floodplain regulations, floodplain permitting process, initiatives that a community can adopt to better promote floodplain management and to earn points through the Community Rating System.
NFIP Floodplain Regulations
Communities that participate in the NFIP must adopt at least the minimum NFIP regulations. More information about the NFIP regulations including the State’s model floodplain ordinances can be found on the Regulations page.
Going Beyond the Minimum NFIP Regulations
Communities are strongly encouraged to adopt more stringent floodplain regulations that go beyond the minimum NFIP regulations. Adopting such standards can improve a community’s resiliency to future floods by reducing potential: loss of human life; property and environmental damage; displacement of residents; disruption of businesses; and the burden on community infrastructure, services and staff. Learn more on the Regulations page.
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.
