Purposes of the NFIPPurposes of the NFIP

Identify & map flood hazard areasProvide a framework for floodplain

management regulationsMake flood insurance available in

Communities that participate in the NFIP


Effects of Hurricane Floyd on Effects of Hurricane Floyd on NCNC

51 deaths

$3.5 billion in damages to homes, roads, businesses, & infrastructure

31,000 jobs lost


NFIP BackgroundNFIP Background

Prior to the creation of the NFIP in 1968:Flood insurance coverage was not availableNo national flood mapping programNo Federal minimum standards for floodplain managementEscalating costs to taxpayers for flood disaster relief


NFIP GoalsNFIP Goals

Reduce loss of life & loss of propertyReduce rising disaster relief costsIncrease importance of hazard mitigation (flood

resistant construction, guide future development, & prohibit development in floodplains that would increase flood levels)

Restore & protect natural resources & functions of floodplains

Decrease taxpayer-funded disaster costsMake Federally backed insurance coverage available

to property owners


Community Participation in the Community Participation in the NFIPNFIP

To join NFIP, communities must submit:Resolution of intent to “maintain in force…adequate land use & control measures” & to cooperate with FEMATheir adopted floodplain management regulations (often are referenced within zoning ordinances, building codes, subdivision ordinances, sanitary ordinances, or floodplain ordinances)


Role of NFIP Participating Role of NFIP Participating CommunityCommunity

Issuing or denying floodplain development &/or building permits

Inspecting all development to ensure compliance with local ordinances

Maintaining records of floodplain developmentAssisting in preparation & revision of

floodplain mapsHelping residents obtain information on flood

hazards, floodplain map data, flood insurance, & proper construction measures


Sanctions for Non-ParticipationSanctions for Non-Participation

No Federal grants or loans for development in Special Flood Hazard Areas (SFHAs) under Federal programs

No Federal disaster assistance to repair insurable buildings located in SFHAs

No Federal mortgage insurance or loan guarantees in SFHAs

Federally insured or regulated lenders must notify applicants seeking loans in SFHAs that: There is a flood hazard The property is not eligible for Federal disaster

relief


NFIP RegulationsNFIP Regulations

Communities must adopt & enforce ordinances that meet or exceed NFIP criteria

NFIP criteria ensures that new buildings will be protected from flood levels shown on digital FIRM

Over time, stock of pre-FIRM buildings should be replaced with post-FIRM buildings & risk to flooding reduced


Definition: Flood Definition: Flood

A “flood” is defined by the NFIP as “a temporary condition of partial or complete inundation of normally dry land areas from:Overflow of inland or tidal waters orUnusual or rapid accumulation or runoff of surface waters from any source”


Definition: FloodplainDefinition: Floodplain

Any land area susceptible to inundation by water from any source

Biloxi, MS, April 1, 2006 - Beauvoir, the National Historic Landmark home of Jefferson Davis, is one of very few wooden homes still standing in the coastal Mississippi

area after Hurricane Katrina.


Biloxi, Miss., August 19, 2010 - Construction is complete on the Jefferson Davis Home. The house was heavily

damaged by Hurricane Katrina in 2005. FEMA provided grants for the project.
