• Abstract:
  Oregon Rockfall Hazard Rating System (RHRS) was field tested at over 50 locations statewide to determine where clarification and improvements to the system were needed. Field use of the system demonstrated many areas where refinements were valuable. These changes along with revised narratives explaining the various criteria have been incorporated into the new RHRS. ; This opportunity confirmed the usefulness of the system as a prioritization tool. Once completed through full scale implementation, the RHRS will allow States to systematically evaluate the rockfall hazards along their highways. This will permit them to prudently direct project funding at their most potentially dangerous sites.
