  1. A 45 MPH design speed roadway with a 2000 ADT has a 6’ shoulder with a 12:1 slope. The shoulder immediately drains into a roadside ditch with 4:1 sideslopes, a bottom width of 4’. The bottom of the ditch is 1.75 feet deeper than the edge of the shoulder. The face of a rock cut is located 7’ from the center line of the ditch, away from the roadway. Is the rock cut located within the clear zone?
