should the flood insurance program continue?

NFIP: Community Floodplain Management
One purpose of the NFIP is to “mitigate and reduce the nation’s
comprehensive flood risk”. (Horn & Brown, p.2)
Before NFIP, only a few states and a few hundred communities
regulated floodplain development. For many communities, the NFIP
was their first exposure to land use planning and community
regulations. (FEMA, PD, p.12)
What is floodplain management?
FEMA, NFIP definition
Floodplain management is a decision-making process that aims to achieve the wise use of the nation's floodplains. "Wise use" means both reduced flood losses and protection of the natural resources and function of floodplains.
Roles of FEMA and the local community
FEMA is responsible for identifying areas at risk in the United States
o Flood
o Flood-related erosion hazards
Communities choose whether to participate in NFIP.
2
Participating communities and FEMA develop Flood Insurance Rate Maps (FIRM) that identify the community’s flood risk and floodplain.
o Creating the FIRM is primarily FEMA’s responsibility
o Implementing the FIRM is the community’s responsibility (Horn & Brown, p.3)
FEMA relies on local governments to notify them of changes to flood
hazards in the community so that flood maps can be updated. (GAO p.4)
Communities Adopt and Enforce Regulations
Communities incorporate the FIRM into law.
The authority to regulate floodplain development belongs to the States
with their capacity to regulate behavior (police powers)
o Require and approve permits
o Inspect property
o Cite violations
Federal government does not have land use authority.
o FEMA has no direct involvement in administering local
ordinances.
o NFIP is based on Federal government’s power to spend under the
Constitution.
(FEMA, PD, pp. 12-13)

Federal Government Sets Standards Community Must Meet
Standards are designed to
o protect buildings (new and existing) from anticipated floods
o prevent new development from increasing the flood threat (GAO, p.4)
Building Standards
Standards depend on the level of risk. Risk is defined through zones on
the map. The community’s Flood Insurance Rate Map (FIRM) identifies
any Special Flood Hazard Areas (SFHA).
o Zone A
o Zone could flood in ‘1 in 100-year’ flood
o Properties have risk of 1% or more of flooding each year
o “The Base Flood Elevation (BFE) is the water-surface
elevation of the base flood, which is the l%-annual-
chance flood, commonly called the 100-year flood”
(Horn & Brown, p. 14)
o Zone V
o more hazardous coastal flood zones
o subject to high velocity wave action
(FEMA, PD, p.7)
4
Standards apply to new construction or existing buildings that are
‘substantially improved’ or ‘substantially damaged’.
If a building is in Zone A
• Residential building: lowest floor (incl. basement) elevated
to or above Base Flood Elevation
• Nonresidential building: either elevated or dry-floodproofed
• Foundations, enclosure walls: flood resistant materials;
openings to let water flow
If a building is in Zone V
• Elevated on piles or columns
▪ Bottom element of lowest floor at or above Base Flood
Elevation
• Structures must be located landward of the reach of mean
high tide
Restrictions on New Development
New development cannot increase the risk of flood damage.
5
In the A Zone
Community must select a ‘regulatory floodway’ for rivers
o area designed to carry the water of the 1-percent-annual-chance
flood without raising the water level of the flood more than one
foot at any point.
o Usually river channel and adjacent floodplains
All development prohibited in floodway
In the V Zone
In these coastal zones, no development can deplete existing natural
barriers.
o man-made alteration of sand dunes and mangrove stands are
prohibited
(FEMA, PD, p. 14)

Community-Level Decisions
New Developments
The community approves new developments in the SFHA.
o Community reviews proposal to ensure compliance with
6
o local ordinances (include FEMA standards)
o requirements of other state of Federal agencies
▪ Wetlands (Army Corps of Engineers)
▪ Endangered Species Act
The NFIP does not prohibit large developments in the SFHA.
Subdivision proposals (including manufactured home parks) need to be
reviewed
o Homes are reasonably safe
o Service facilities (utilities) constructed to minimize flood damage
(FEMA, PD, p. 13)
Status of Existing Buildings
Community decides whether a property has been substantially
improved or substantially damaged. These classifications require the
property to be brought up to NFIP standards.
The relationship between FEMA and local communities
The NFIP structure fits a principal-agent framework.
o FEMA sets the standards and bears the risk. (principal)
o Communities need to implement the standards to manage the
risk. (agent)
7
How does the federal government ensure compliance?
Incentives
The ‘carrot’ for the community is the ability to buy flood insurance.
FEMA provides technical assistance to help and encourage community
compliance
o workshops
o formal floodplain management courses
o direct responses to inquiries from local officials
Monitoring
FEMA can monitor participating communities in several ways.
Through the paperwork that is filed
o Applications for flood insurance policies
o Requests to remove properties from floodplain designation
Community Assistance Contact (CAC)
o Establish contact to see if problems exist
o Phone call or short visit
Community Assistance Visits (CAV)
o Viewed as opportunity to provide technical assistance
o tour of floodplain
8
o meet local officials involved
o examine records on permits and variances
If the CAV reveals problems, communities are given time to address
them.
Penalties
If a community makes no effort to resolve issues FEMA has identified, it
can be put on probation.
o Flood insurance remains available
o An additional charge ($50) is added to the premium for at least 1
year
(FEMA, PD, p. 19)
A community can be suspended from the NFIP if
o The problems remain unresolved
o Does not adopt an approved FIRM and management standards
within the required timeframe
o Repeals or revises the floodplain standards so that they fail to
meet FEMA’s minimum standards
If the community is suspended from the program, federally-backed
flood insurance not available in the community. There are limitations
on other federal assistance.
9
One of the primary reasons communities comply is to avoid disruptions
in the real estate market that would result with the potential loss of
flood insurance. Federally-backed mortgages require flood insurance
for properties mapped into an SFHA.
