Protecting Your Home > What is your flood hazard?
|
1. Check with your community officials for flooding information in your area. Some questions you might ask are: - Where does the water come from?
- Are you in the mapped Special Flood Hazard Area or floodway as shown on your FIRM?
- Are you in coastal high hazard area or V Zone as shown on your FIRM?
- How bad has it been in the past?
- How bad could it be? (Remember, the next flood can be worse than the last one.)
- What is an appropriate flood protection level? (How high should you prepare for?)
2. Are you protected by levees?
Areas protected by levees face two types of flood hazard: - Deep and sudden flooding due to overtopping or levee failure. This usually occurs as a result of high river or lake levels, or a Tropical Storm or Hurricane. Because there will be some warning of these conditions there should be adequate time to evacuate.
- Shallow flooding from rainstorms. Areas protected by levees are flat and need pumps to drain stormwater runoff. There may not be much of a warning for this type of flooding.

- Does water flow away from your house or does it tend to stand next to your walls?
- Is the ditch, stream or storm sewer that takes water away clear of debris or obstructions?
- Do the downspouts from your roof gutters direct water well away from your house?
- Do you have a sump pump? If so, does it direct water well away from your house?
- Stormwater mitigation best practices from the EPA
Once you have the answers to these three questions, the next step is to look at your building's Foundation.
