Background State highway departments and transportation agen- cies have a continuing need to keep abreast of operat- ing practices and legal elements of specific problems in highway law. The NCHRP Legal Research Digest and the Selected Studies in Transportation Law (SSTL) series are intended to keep departments up-to-date on laws that will affect their operations. Foreword Slope failures pose serious risks for state transporta- tion agencies and federal agencies that own or maintain roads, highways, and/or adjacent property. These enti- ties may be subject to liability for unstable slope related incidents involving administrative and judicial claims for personal and property damage. Many transportation agencies have adopted unstable slope management pro- grams and standards as part of a larger effort to provide an efficient and effective methodology to prevent or con- trol landslides or rockfalls. These programs typically use a ranking or rating scale to help determine which slopes should receive preventive or corrective maintenance. This digest provides a detailed description of several specific unstable slope management programs, includ- ing the type of data collected and rating systems that are utilized. The digest presents an analysis of govern- mental immunity and discretionary waivers of immuni- ty and the application of such to transportation activities and employees, especially in the context of highway slope failures. Pertinent cases are analyzed, with special attention given to expert testimony elicited to support or defend a claim. This digest would be useful to federal and state trans- portation agency personnel particularly in the areas of street and highway construction, planning, main- tenance, asset management, and attorneys practicing transportation law.
