Flood Response

The City of Sultan sits at the confluence of the Sultan and Skykomish Rivers. Its location provides wonderful recreation opportunities. However, it also presents challenges, especially during times of heavy rain when the rivers rise and overflow their normal channels. About 30% of Sultan residents are located within the Flood Hazard Area.
