Floodplain Map

Johnson County Stormwater Management has released a new study that has resulted in changes to the floodway and floodplain map for Mission Hills.

The new map as been adopted by the City Council, the State of Kansas and the Federal Emergency Management Agency (FEMA).

We have a large copy of the map at City Hall for review, but you can also view small sections of the map here:

Primary Goals of Johnson County Watershed Studies

  • Update the current FEMA regulatory floodplain maps
  • Identify floodplain boundaries for existing and future development
  • Help reduce the creation of future stormwater problems in areas that are likely to flood as development occurs
