Flood Preparedness

Floods are one of the most common hazards in the United States. Flood effects can be local, impacting a neighborhood or community, or very large, affecting entire river basins and multiple states.

Flash Floods
However, all floods are not alike. Some floods develop slowly, sometimes over a period of days. But flash floods can develop quickly, sometimes in just a few minutes and without any visible signs of rain. Flash floods often have a dangerous wall of roaring water that carries rocks, mud, and other debris and can sweep away most things in its path.

Overland Floods
Overland flooding occurs outside a defined river or stream, such as when a levee is breached, but still can be destructive. Flooding can also occur when a dam breaks, producing effects similar to flash floods.

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, culverts, dry stream beds, or low-lying ground that appear harmless in dry weather can flood. Every state is at risk from this hazard.

Before a Flood
To prepare for a flood, you should:
  • Avoid building in a flood-prone area unless you elevate and reinforce your home
  • Elevate the furnace, water heater, and electric panel if susceptible to flooding
  • Install check valves in sewer traps to prevent floodwater from backing up into the drains of your home
  • Contact community officials to find out if they are planning to construct barriers (levees, beams, flood walls) to stop floodwater from entering the homes in your area
