Dr. Peter Schiess is a professor of Forest Engineering from the University of Washington. His work centers on Road Construction. Poorly constructed, non paved roads are the greatest cause of erosion, and many new roads were being (badly) built to meet the demand of developers and ranchers. The seminar was attended by local road builders as well as land owners and representatives of local environmental agencies. The quality of road building in the area has improved considerably as Dr. Peter continues to return at the invitation of local landowners to advise and supervise. Here are some materials from his presentation:
