Localized Flooding

Water in basement, home, business

If you cannot determine the source of the water entering your home, contact your city hall or a plumber.

Water in yard, drives, drainage areas

If you have water pooling in your yard for long periods of time, contact your city to determine if this is a city responsibility issue or a homeowner issue.

Water standing in the streets for long periods of time, clogged/blocked inlets, culverts and bridges?

Contact your city and inform them of the situation.

Water in car, truck, vehicles

Restoring cars and vehicles that have been partially or completely submerged under water requires professional attention. Check with your dealer or look in the telephone directory for automobile service and repair firms.

Floodplain Management


The Stormwater Management Program (SMP) contracted for seven watershed studies between 1998 and 2002. These studies were part of a county-wide effort to provide the following information:

  1. identify existing and potential future flooding problems;
  2. develop planning solutions to mitigate flooding problems;
  3. generate new 1% chance (100 year) floodplain maps based on current conditions and fully urbanized conditions; and
  4. develop the data required by the Federal Emergency Management Agency (FEMA) to update FEMA regulatory 1% chance floodplain maps.

Through this effort, the SMP and the cities have created a tool that will assist in providing a public service to help protect the welfare and safety of Johnson County residents and visitors.


Additional Information

The floodplain mapping is complete and was adopted by FEMA on August 3, 2009. Johnson County floodplain mapping information can be found at the following locations:

If you have questions about the floodplain information or want additional information, contact the floodplain administrator for your community.

Flood Safety


If you are experiencing a life threatening situation, call 911. Otherwise contact your city to request help.

Flood Safety

Before a flood:

  • Prepare an emergency kit that includes non-perishable food, drinking water, a flashlight, and basic medical supplies. Find a complete list of a basic disaster supplies kit at www.ready.gov/kit.
  • If your basement has the potential for flooding, store your kit on a shelf and elevate boxes and other items off the floor.

During a flood:

  • Do not walk or drive through moving water. Although appearing harmless, water only 7 inches deep can move rapidly and with great force, posing a significant threat.
  • Never drive through a flooded road, always "Turn Around, Don't Drown". 
  • Stay away from downed power and electrical lines.
  • Stay away from streams during storms as water can rise rapidly and without warning.
  • Keep children away from creeks or storm drains during and after a storm.

After a flood:

  • If the path is dry, turn off the electricity at the main breaker box or fuse box – if you have to step in water to do so, call an electrician.
  • Don't use wet appliances or motors until they have been taken apart, cleaned and dried.
  • Watch your step inside and outside: surfaces may be slippery and covered with debris.
  • Use a flashlight to inspect for damage.
  • Because it is difficult to identify if water in a basement is stormwater or from the sanitary sewer, treat all surfaces and furnishings as if they are unhealthy.
  • Protect yourself with good personal hygiene: wear rubber boots and gloves; wash hands with soap and water; protect open sores or wounds from contact with the water.
  • Disinfect and clean everything that got wet. If in doubt, throw it out.
  • Visit Johnson County Wastewater for specific guidelines for cleaning up after a sewer backup.
  • Find out if a "Boil Water" order is in effect for drinking water.
