National Flood Insurance Program: 

The FEMA Flood Map Service Center (MSC) is the official public source for flood hazard information produced in support of the National Flood Insurance Program (NFIP). Use the MSC to find your official flood map, access a range of other flood hazard products, and take advantage of tools for better understanding flood risk.

 See your map and learn how to read it so you can make informed decisions about protecting your property, both financially and structurally.

FLOOD AWARENESS

Floods are among the most frequent and costly natural disasters, and are not uncommon for certain areas within the City of Warwick and Kent County. Conditions that cause floods include coatsal storm events, seasonal high-rides, heavy or steady rain for several hours or days that saturates the ground, or flash floods occurring suddenly due to rapidly rising water along a stream or low-lying area.

Flood effects can be local, impacting a neighborhood/community or large affecting the entire county.  And there are major differences between flash floods and those that develop slowly, over a period of days and even weeks.

Be aware of flood hazards no matter where you live, but especially if you live in a low-lying area, near water or downstream from a dam. Even very small streams, gullies, creeks, or low-lying ground that appears harmless in dry weather can flood and become potentially dangerous.

Defining Flood Risks

Flooding can happen anywhere, but certain areas are especially prone to serious flooding. To help communities understand their risk, flood maps (Flood Insurance Rate Maps, FIRMs) have been created to show the locations of high-risk, moderate-to-low risk and undetermined-risk areas. Here are the definitions for each:
 
High Risk Areas
(Special Flood Hazard Area or SFHA)
In high-risk areas, there is at least a 1 in 4 chance of flooding during a 30-year mortgage. All home and business owners in these areas with mortgages from federally regulated or insured lenders are required to buy flood insurance. They are shown on the flood maps as zones labeled with the letters A or V.
 
Moderate- to Low-Risk Areas
(Non-special Flood Hazard Area or NSFA)
In moderate- to low-risk areas, the risk of being flooded is reduced but not completely removed. These areas submit over 20% of NFIP claims and receive one-third of disaster assistance for flooding. Flood insurance isn't federally required in moderate-to-low areas, but it is recommended for all property owners and renters. They are shown on flood maps as zones labeled with the letters B, C or X (or a shaded X).
 
Undetermined Risk Areas
No flood-hazard analysis has been conducted in these areas, but a flood risk still exists. Flood insurance rates reflect the uncertainty of the flood risk. These areas are labeled with the letter D on the flood maps.

Determining the Risk

To identify a community's flood risk, FEMA conducts a Flood Insurance Study. The study includes statistical data for river flow, storm tides, hydrologic/hydraulic analyses, and rainfall and topographic surveys. FEMA uses this data to create the flood hazard maps that outline your community's different flood risk areas.

Floodplains and areas subject to coastal storm surge are shown as high-risk areas or Special Flood Hazard Areas (SFHAs). Some parts of floodplains may experience frequent flooding while others are only affected by severe storms. However, areas directly outside of these high-risk areas may also find themselves at considerable risk.

Understanding Your Area

Changing weather patterns, erosion, and development can affect floodplain boundaries. FEMA is currently updating and modernizing the nations Flood Insurance Rate Maps (FIRMS). These digital flood hazard maps provide an official depiction of flood hazards for each community and for properties located within it.

FEMA has published almost 100,000 individual Flood Insurance Rate Maps (FIRMs).

FLOOD TERMS

Terms used to identify flood hazards:

Flood Watch means flooding is possible. Tune in to NOAA Weather Radio, commercial radio, or television for further information.

Flash Flood Watch means flash flooding is possible. Be prepared to move to higher ground; listen to NOAA Weather Radio, commercial radio, or television for further information.

Flood Warning means flooding is occurring or will occur soon; if advised to evacuate, do so immediately.

Flash Flood Warning means flash flooding is occurring; seek higher ground on foot immediately.
