Flood Insurance Rate Maps are published by the Federal Emergency Management Agency (FEMA). Since Clallam County participates in the federal Flood Insurance Program, permits issued by Clallam County must address activities conducted within the flood zones shown. The map images accessed from this page represent the legal delineation of flood hazard zones, as used in the Flood Insurance Progam.
Why the Change to web maps?
Due to accuracy issues, the "100 year Flood" layer has been removed from the web maps.
Instead, map users are being encouraged to consult the actual Flood Insurance Rate Maps (FIRM), whose images are linked from this page, and from the web maps. Only the FIRM maps are legally valid.
A more technical explanation is included at the bottom of this page.
||This page has a clickable index map which identifies all the Flood Insurance Rate Map (FIRM) panels in Clallam County. Clicking on any of the panels will open a PDF of that panel. (Note that this is a simple image map, with no zooming in or out, no layers to turn on or off.)
Using the Web Maps to access FIRM maps PDF Files
The Flood Map Index layer is present on both the Parcel Express and the Critical Areas and Parcel Web Maps
To use either of these maps to access FIRM map panels for a specific spot on the map,

- go to the layer list in the bottom right corner of the map viewer.
- The Flood Map Index layer will be at the top of the list
- check the square box (to make the layer visible) and
- select the round button (to make the layer active).

Previously, the web maps included a "100 year Flood" layer, produced by FEMA, depicting a digitized version of the 100 year (1%) Flood Zones from the FIRM maps. Because the base map on which this data was mapped is distorted relative to current geographic information, the flood zones depicted often landed well outside the actual intended location. Despite disclaimers about map accuracy issues, it was decided that this inaccuracy had the potential to mislead map viewers about the applicability of flood zone regulations to specific parcels. Since the legal definition of these zones is based on the published maps, any definitive inquiry about FEMA designated flood zones must consult the actual FIRM maps, whose images are accessible from this page, and from the web maps.
The FIRM maps are in the later stages of being replaced with new digital data. Once the updated version of this data is released, we will evaluate the appropriateness of overlaying it with Clallam County data.
