1 Managing the Risk of Unstable Slope Failure

Managing the Risk of Unstable Slope Failure / Washington State DOT

The Washington State DOT recognized the potential safety risk to highway travelers and the adverse impact on regional commerce associated with unstable slope failure. To become more proactive in managing this risk, WSDOT developed the Unstable Slope Management System (USMS) that provides a method for evaluating known unstable slopes and using the information to prioritize slopes for funding of proactive stabilization efforts. The mitigation objective of the unstable slope management program is to sustain a desired state of good repair and low risk over the life span (> 20 years) of known unstable slopes and constructed geotechnical assets at the lowest practicable cost.
