A common pavement maintenance practice that extends pavement life and provides a good driving surface. The City of Oak Harbor is responsible for the maintenance of 71 centerline miles of roadway. Asphalt surfaces should last between 15 to 20 years (varies depending on traffic). Roads are reviewed annually to determine if pavement preservation is required. Contractors are hired through a bidding process to perform the work.
