Green Technologies for Reducing Slope Erosion, Preliminary Investigation

As climate change alters precipitation patterns, departments of transportation will increasingly face the problem of slope failures. The California Department of Transportation (Caltrans) conducted this Preliminary Investigation to identify innovative strategies for reducing the risk of roadside slope erosion. They hope to implement the latest vegetative and soil-based solutions for reducing the volume of highway stormwater runoff on slopes and in water conveyance systems.

The Caltrans team reviewed recent research, national guidance, and related efforts of other state DOTs; emerging “green” solutions; and biotechnical guidance related to slope design, soil engineering, and vegetation selection and management. This report is a synthesis of their findings, and as such, it is useful to other states and localities facing the same issues.
