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. 

Verdigris Custom Watershed

The Verdigris Custom Watershed Floodplain Mapping update project kicked off on January 28, 2020, in the cities of Howard and Eureka. The Discovery Meeting was held virtually on April 21, 2020. Data development for regulatory maps will began in 2022 for Chautauqua, Elk and Greenwood Counties. This website will be updated with relevant content as the project moves forward.
