Document Description
Project proposes to add stabilization measures to the head cut beneath the accessible trestle walkway, near the main park entrance at Indian Grinding Rock State Historic Park to reduce the potential for further erosion of the head cut. The head cut is created by the discharge of culverts under both the park entrance road and Pine Grove Volcano Road. Current conditions of the head cut include actively expanding the 7’ – 8’ drop in the channel that risks damaging existing infrastructure including the trestle walkway, the park entrance road, and Pine Grove Volcano Road.
