The activities will take place by positioning an excavator on the excavator access road along an open, un-vegetated area along the northern bank of Auburn Ravine. The excavator will access and relocate existing boulders in the boulder apron without significantly impacting the streambed, bank, riparian vegetation, or habitat.
