Flood Risk Map

Enter your property address in the field in the upper-right of the flood risk map to see if your property is in a flood risk area. To see what the colors and lines mean, click on the Legend toggle in the upper left. The Legend toggle on the map looks like this icon.

If there is no blue or green overlay as listed in the Legend, the property address you have entered is not located in a flood risk area.

It is important to be aware of the risk of flooding in your area so that you can be prepared to protect yourself and your loved ones. Learn how to be prepared in the event of a flood by visiting the Resources page.

To see additional features, visit the King County iMap and click on the Layers icon in the toolbar on the upper right. The Layers option on the iMap looks like this icon.
