Community Information and Initiatives

Information about a community's minimum NFIP requirements including the floodplain permitting process , initiatives that a community can adopt to better promote floodplain management and to earn points through the Community Rating System, and information about mitigation.

Minimum NFIP Floodplain Regulations

Communities that participate in the NFIP must adopt at least the minimum NFIP regulations, which are contained in the state's model floodplain ordinances.

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

OEP 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. Also, as floodplain development increases, the floodplain storage area decreases thereby causing adverse flooding affects on others in the floodplain and watershed.

OEP has compiled a list of communities pdf file 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.

The following documents detail floodplain regulations that a community can adopt that exceed the minimum NFIP regulations.

Community Rating System

The objective of the Community Rating System (CRS) is to reward communities that are doing more than meeting the minimum NFIP requirements to help their citizens prevent or reduce flood losses. The CRS also provides an incentive for communities to initiate new flood protection activities.

In CRS, communities earn points for adopting and enforcing certain floodplain management regulations and activities. The number of points a community accumulates decides what percent discount their residents will receive on their flood insurance premiums. Many times a community will receive points for activities or regulations that they are already conducting or enforcing.

A community can receive points for several activities that are organized under the following four categories: Public Information, Mapping and Regulations, Flood Damage Reduction, and Flood Preparedness.

The CRS Coordinator's Manual is the guidebook for the CRS and sets the criteria for CRS classification. It explains how the program operates, what is credited, and how credits are calculated. Although it is primarily a reference for CRS activities and credits, it can also help guide communities that want to design or improve their floodplain management programs.

New Hampshire Communities Participate CRS
Community CRS Class Percent Discount on Flood Insurance
Keene 8 10%
Marlborough 9 5%
Peterborough 8 10%
Winchester 9 5%

Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. Mitigation is taking action now—before the next disaster—to reduce human and financial consequences later (analyzing risk, reducing risk, insuring against risk). Effective mitigation requires that we all understand local risks, address the hard choices, and invest in long-term community well-being. Without mitigation actions, we jeopardize our safety, financial security, and self-reliance.
