Floodplain Mapping Projects

FEMA has available several services for different phases of a mapping project. Preliminary, Pending and Effective products can be downloaded on from the Map Service Center. FEMA also maintains several map viewers:

National Flood Hazard Layer - displays the effective digital data
> Flood Map Changes Viewer  - includes the Preliminary and Pending digital map data, with a Changes Since Last FIRM layer that compares the Preliminary/Pending data with the effective data


KDA maintains project-specific map viewers for active projects that are based on the same digital data. The web links are included on the project pages below. 

Frankfort Levee PMR


The purpose of this project is to update the floodplain maps around Frankfort, Kansas. The current effective flood insurance rate map (FIRM) for Marshall County, Kansas, currently doesn't show flood hazard behind the Frankfort Levee system. However, the Frankfort Levee system is currently unaccredited and the draft floodplain modeling has been developed to show the extent of the flood hazard in Frankfort. This webpage will be updated as the project moves forward.
