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.

Community Resources

Seed Mixes

A variety of seed mixes are used to help shorten soil stabilization and long-term reclamation. These mixes often include native species and mixtures that are beneficial to elk/deer winter ranges and sage grouse.
