ROCKFALL HAZARD RATING SYSTEM: IMPLEMENTATION MANUAL

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 tool for managing rockfall sites adjacent to highways. The system is proactive by design and provides a rational way to make informed decisions on where and how to spend construction funds. This manual documents the components of the RHRS, the steps an agency should follow to implement the system, and discusses the level of commitment required. It also describes the benefits of implementation.
