Development of the Rockfall Hazard Rating System (RHRS) is complete. The system has been fully tested and implemented by the Oregon Department of Transportation. The RHRS is a process used in the management of rockfall sites adjacent to highways. The system is proactive by design, providing a rational way to make informed decisions on where and how to spend construction funds in order to reduce the risks associated with rockfall. This Participants' Manual documents the components of the RHRS and the steps an agency should follow to implement the system, and discusses the level of commitment required. The benefits of implementation and the limitations of the system are also described. The manual serves both as a field guide and as a desk top reference for those who perform the slope ratings and those who use the resulting database in establishing rockfall remediation designs and construction priorities.
