This is a view of the benching excavation and the drainage channel below it. The channel will eventually handle the runoff from inside the rock buttress and carry it down to the natural streams, while the silt basin helps dissipate the velocity of the water as it exits the pipes. Each bench is about 12'-15' high. Photo taken October 1998.
