Rock Excavation

The process of excavating rock from material sources often requires blasting in the quarry. The potential damage from ground vibration, air blast and flying debris is a major consideration when planning excavation activities. ODOT and its contractors make every effort to minimize potential impacts on neighboring properties from this type of work.
