How you benefit

Economic incentive
Chip sealing preserves the integrity and life of deteriorating roadway by applying a Bituminous Surface Treatment (BST) seal coat of oil and gravel (chips) to the existing pavement. Restoration is necessary before the underlying road structure is damaged, requiring a much more expensive rebuild.

Partnerships & cooperation
WSDOT addresses the concerns of tribal nations using the process outlined in Section 106 of the National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.
