Flash Flooding and Drainage Issues

Posted by jshockley at Jul 07, 2015 12:12 PM |

The City of Tonganoxie has received several concerns from residents regarding yesterday’s storms and the associated flash flooding and drainage issues. The City is aware that numerous streets and areas of town became flooded yesterday after the City experienced nearly 6 inches of rain in one hour. While the City is constantly evaluating our infrastructure and identifying improvements that need to be made as funding becomes available, including stormwater improvements, when we receive a high volume of precipitation in a very short amount of time, there is very little even the most sophisticated stormwater system can do to mitigate the effects of flooding. In fact, the Federal Emergency Management Association states that in the past 5 years, all 50 states have experienced floods or flash floods. While flash floods are impossible to prevent, there are many steps our residents can take to be prepared for this type of event:

  • Do not drive through flooded areas; vehicles can be swept off the roadway.
  • If you are in a low-lying area, move to higher ground.
  • Stay away from streams, concrete channels, and other drainage structures.
  • If you are on a road, watch for flooding at dips, bridges, and low areas.
  • Report road flooding to 911.
  • Build an emergency kit and make a family communications plan.
  • Avoid building/buying property in a floodplain.
  • Construct barriers to stop floodwater from entering the building and seal walls in basements with waterproofing compounds.
  • If you live in a high-risk flood zone, in a low-lying area, or near a creek, stream, or other drainage structure, consider purchasing flood insurance, as flood damage is almost never covered by homeowners insurance.
