The Federal Emergency Management Agency is nearing completion of updates to the floodplain maps, also known as Flood Insurance Rate Maps (FIRM). Preliminary FIRMs are under review for Wyandotte County. The new Flood Insurance Rate Maps reflect updates to Wolf Creek, Brenner Heights Creek, Little Turkey Creek, and Betts Creek. The Unified Government of Wyandotte County/Kansas City, KS is hosted a public information open house regarding the new Flood Insurance Rate Maps for residents of Wyandotte County and its communities.

Flood Protection Information Directory

Know Your Hazard- Wyandotte County is subject to flooding from the Kansas River, Missouri River, Turkey Creek, Brenner Heights Creek, Jersey Creek, and other channels and streams. As a highly urbanized area, portion of the community may also experience flooding from storm water runoff.  The local floodplain administrator can tell you if you are in or near a regulated floodway, or in an area known for repetitive flooding. The floodplain administrator can be reached at 913 573-8664. An online web-mapping application is available for viewing floodplain boundaries, parcels and more at DotMaps http://www.wycokck.org/GSS/DotMaps.aspx

Protect Natural Floodplain Functions- The preservation of open space is the most effective practice for avoiding flood damage. In Wyandotte County, preservation and restoration of natural banks along the Kansas River, Missouri River, Turkey Creek and smaller channels are key components of local floodplain management. Wyandotte County requires a floodplain development permit for all work to be done within the regulated Special Flood Hazard Area; A zones and floodway. Private property owners can do their part to maintain natural floodplain functions by working to preserve drainage ways, natural channels, ditches and open space on their property. Additional information on the importance of maintaining floodplains can be found at:  Protecting Floodplain Resources
