Transportation corridors, depending on the geology and topography, will intercept unstable slopes and slope failures. These slope failures range in severity; some cause property damage and block traffic, while others go unnoticed by the general public. Although slope failures that cause significant blockages, property loss, or loss of life are not common, any slope failures along transportation corridors remain a thorny issue facing state transportation agencies, which are responsible for providing and maintaining safe routes with limited budgets. Consistent with the federal efforts for overall disaster preparedness and risk reduction, many state transportation agencies are moving towards proactive risk management strategies for mitigating unstable slope issues. |
