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. 

Osawatomie


The Osawatomie Flood Hazard Mapping project has developed draft floodplain maps to reflect that the city-owned levee has been accredited and the draft maps will show that the levee provides a reduce risk to flooding from the 1% annual chance flood. The project began in February 2017 to update the FIRM panels for Osawatomie but the project was placed on hold while the levee was certified. The levee accreditation was completed in July 2022 and a re-kickoff meeting was held on August 8, 2022.
