Dust

Dust Overview

The Tri-Cities are located in the most arid part of Washington State. In fact, the annual rainfall of 6-8 inches is drier than most parts of Arizona. Because of the combination of climate, soil conditions, and human interaction with the land, dust is often an inevitable result.

Before starting any work that destabilizes the soil, the Proof of Contact: Soil Destabilization Notification form listed below must be completed. Benton County and its cities will need a copy of the completed form before they issue permits.
