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. 

Middle Smoky Hill Custom Watershed


The Middle Smoky Hill Custom Watershed Floodplain Mapping update project will produce Base Level Engineering (BLE) floodplains for the entire custom watershed. Enhanced data development is anticipated to begin in 2024 for the areas that will undergo a regulatory update. Ellis County was not included because it is being updated as part of a separate county-wide project. This website will be updated with relevant content as the project moves forward. The Kickoff Meeting was held virtually on November 17, 2020, and the Discovery Meeting was held virtually on March 10, 2021.  The presentation slides are located below.
