Contact Info: (660) 747-2666

On September 25, 1990 the Johnson County Commission signed a resolution adopting floodplain management control measures to reduce future flood losses pursuant to Chapter 49.600 RSMo.

Floodplain maps for the unincorporated areas of Johnson County as well as the cities of Warrensburg, Holden and Knob Noster are available for viewing in the Emergency Management office, as well as base flood elevations of some of the bridges in the county for permit purposes.  If you are building in a special flood hazard area in the unincorporated areas of Johnson County, you will need to obtain a permit from the Emergency Management office.  If you are building in the incorporated city limits, you will need to contact the respective city hall.
