CASTLE ROCK – Erosion Control and Revegetation
Erosional processes are a major concern in the restoration of disturbed ground that is subject to the forces of either wind or water, or that are located on steep slopes. The Castle Rock erosion control and revegetation project, located in the foothills above Wenatchee, Washington, involved a small piece of land that had been excavated out of a hillside to provide more vertical space for the power line above it. In order to prevent erosion on the steep slope created by excavation, BFI undertook the process to revegetate and stabilize the site in March 2014 by first broadcast seeding native grasses, followed by the installation of a woven straw erosion control blanket. In addition, BFI strategically placed straw waddles at the site to prevent movement of the soil during the revegetation process.
