Background
Illinois has one of the largest inland systems of rivers, lakes and streams in the
United States. Nearly 15% of our total land area (or 7,400 square miles) is subject to
flooding. Total stream flow in Illinois averages over 25 BILLION gallons per day!
We are very flood prone.
Floods are
an inevitable natural event. Floods are by far the most common natural disaster in Illinois,
accounting for well over 90% of the declared disasters. It is estimated that over 250,000
buildings are located in floodplains of Illinois.
Unwise floodplain development further increases property damage and potential loss of
life from flooding. There are almost always adverse impacts upon the citizens, local
governments and state government from both physical and financial damages. Therefore,
it is very important to develop and expand flood risk reduction activities in order to
yield positive, long-term benefits. The Illinois Emergency Management (IEMA) has
information on risk identification, mitigation planning, and disaster awareness.

THE NATIONAL FLOOD INSURANCE PROGRAM (NFIP)
The National Flood Insurance Program (NFIP) was created by Congress in 1968 to slow ever
rising disaster relief costs and reduce the loss of life and property caused by flooding.
To join the NFIP, a community must adopt and enforce local floodplain management regulations.
In exchange, the Federal Emergency Management Agency (FEMA) makes flood insurance, disaster
assistance, and mitigation grants available to that community.
The Illinois Department of Natural Resources/Office of Water Resources (IDNR/OWR) is the state
coordinating agency for the NFIP. The NFIP is a voluntary program based on a mutual agreement
between the federal government and the local community. Currently, 82 counties and 770
communities in Illinois have adopted a local floodplain ordinance and participate in the
National Flood Insurance Program.
To find out how your community can join the NFIP please see

Floodplain Maps
FEMA and the State of Illinois have identified floodplains the state. These floodplain maps
are used by communities, planners, lenders, and insurance agents to identify flood risk areas.
Floodplain maps of Illinois can be viewed on line at:

On occasion, residents in Illinois will dispute a property's location within a floodplain.
FEMA has a process to remove a property from a floodplain. However, before this happens a
property owner must provide FEMA with technical or elevation data to prove the property is
not at risk of flooding. Information on map changes can be found at:
http://www.fema.gov
Flood Insurance
The average homeowners policy does not cover flood damage. Therefore, we encourage citizens to
purchase flood insurance. Information on flood insurance can be found at:

FLOODPLAIN REGULATIONS
Both FEMA and the Illinois Office of Water Resources have established floodplain
management standards for communities to follow. These regulations prevent future
flood losses from occurring. Adopting the state model floodplain
ordinance
is the first step. This ordinance is being used by the majority of communities in
Illinois. Please contact OWR or FEMA to obtain copies of the appropriate model
ordinance for your community.
Since the 1993 the state has aggressively targeted the most flood prone structures using a variety
of FEMA and state mitigation funds. Nearly 50% of the state's most flood prone structures have now
been mitigated saving the taxpayers millions of dollars every year. However, additional mitigation
work needs to be done to continue to reduce flood damages. Mitigation programs are available to
address flood losses:

COMMUNITY RATING SYSTEM = REDUCED FLOOD INSURANCE PREMIUMS
Many communities in Illinois have gone well above state and federal minimum standards to adopt
higher regulatory standards. Currently, 45 communities in Illinois get discounted flood
insurance premiums for exceeding state and federal minimum standards. To see how your community
can benefit, see this link:
