COST AND BENEFITS OF ROAD, DUST CONTROL IN SEATTLE'S INDUSTRIAL VALLEY

The paving of gravel roads with an average daily traffic (ADT) over 15 is a least cost method for reducing suspended particulate in the air in Seattle. It is also a good business investment when the ADT exceeds 100. In a study done in Seattle's Duwamish Valley the impact of road dust on air quality was measured by obtaining dust emission factors for vehicles traveling at 10, 20, and 30 mph on gravel as well as dusty paved roads. Nineteen miles of gravel roads and 110 miles of dusty paved roads contributed 2700 tons/year of particulate, of which 700 tons were below 10 microns. Paving or oiling such roads will produce benefits of $3,881,000 yearly in household cleaning, health care, sewer, vehicle operation, and road maintenance costs as well as an increase in property values.
