Robert Searns has been serving as planning and development specialist for a multi-disciplinary team invited by the National Park Service and the Grand Canyon National Park Foundation. The team included ten experts recruited nationwide to address problems of overcrowding and vehicular traffic. The challenge was to entice park visitors to leave their autos behind and use on-motorized means to experience the canyon. The team developed concepts for a multi-use, non-motorized greenway trail system along the rim. The team also formulated an implementation plan. Specifically, Searns helped develop North and South Rim greenway trail layout concepts, design principles, cross sections, proof of concept pilot project plans and budget.
