Slope failures pose serious risks for state transportation agencies and federal agencies that own or maintain roads, highways, and/or adjacent property. Many transportation agencies have adopted unstable slope management programs and standards as part of a larger effort to provide an efficient and effective methodology to prevent or control landslides or rockfalls.
The TRB National Cooperative Highway Research Program's NCHRP LRD 82: Potential Liability Associated with Unstable Slope Management Programs provides a detailed description of several specific unstable slope management programs, including the type of data collected and rating systems that are utilized.
