FEMA has introduced several enhancements to the Map Service Center (MSC) that expand access to National Flood Hazard Layer (NFHL)-based dynamic maps throughout the mapping lifecycle. These improvements simplify access and make the flood hazard information easier to use.

When users enter an address or location, the map results now show interactive flood hazard information. Most FIRMettes (a portion of the Flood Insurance Rate Map [FIRM] that is easier to print) are created dynamically from the NFHL. Changes also include an improved viewer for the NFHL that provides customizable, interactive views and printable products. There are also big improvements for interacting with preliminary data through the Flood Map Changes Viewer that shows the preliminary and pending flood hazard data, the preliminary Changes Since Last FIRM (CSLF), and includes the Preliminary Map Comparison Tool. The new draft National Flood Hazard Layer Viewer, allows FEMA to share draft flood hazard data as well as draft CSLF data when appropriate. Contact MSC Help if you need more information.
