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.
