The Oregon Department of Transportation maintains quarries as part of a statewide material source network. ODOT uses these material source locations to obtain rock material for use in construction, maintenance and emergency repair projects, as well as stockpiling excess material for future use or reclamation.
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 for ODOT as it plans excavation activities. ODOT and its contractors make every effort to minimize potential impacts on neighboring properties from this type of work.
A variety of seed mixes, including native species and mixtures beneficial to elk/deer winter range and sage grouse, are used to help shorten soil stabilization and long-term reclamation.
