Dust Abatement Program

Winslow Avenue

This multi-year project is in accordance with EPA requirements and part of a larger countywide plan to reduce air pollution.

MCDOT maintains nearly 700 miles of unpaved roads throughout the valley. With the population increasing in our outlying/rural areas, dust suppression has become a major concern as these roads are significantly contributing to the airborne pollution in our dry desert community. MCDOT is committed to you, the citizens, and pledges to continue this aggressive program to reduce our airborne pollution and increase our air quality.
