Quantifying and Prioritizing Road Impacts

The Forest Service has developed:

"a process and a set of tools for analyzing the impacts of roads on forested watersheds. GRAIP combines a road inventory with a powerful GIS analysis tool set to predict sediment production and delivery, mass wasting risk from gullies and landslides, stream diversion potential, culvert maintenance and fish passage at stream crossings."

The attached memo gives a brief introduction to the GRAIP process/tool, which is, for example, being used to assess the effectiness of projects implemented through the Legacy Roads and Trails Remediation Initiative in the Pacific Northwest region of the Forest Service.
