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. 

Upper Solomon Saline Custom Watershed

The Upper Solomon - Saline Custom Watershed Floodplain Mapping update project will produce Base Level Engineering (BLE) floodplains for the entire custom watershed. These production started in 2022 and should be available in the Fall of 2022. We will work to identify areas to scope for regulatory updates as the project moves forward and update this website with relevant content.
