We propose a framework for permitting of sediment delivery from forest roads associated with multiple forest activities, outfalls and varied ownership within a forested watershed. The approach employs well-known quantitative sediment models that are informed by GIS-based forest road, culvert, and stream databases typically maintained by industrial forest landowners. As a proof-of-concept, we applied this framework in a region with highly erosive soils, high levels of precipitation, and intensive forest management. We found the framework to be capable of producing reliable estimates. Our framework enabled crossing-by-crossing estimates of sediment delivery from multiple forest activities that could be rolled-up at various scales. For smaller landowners, with limited activities and haul routes, this is a simple and transparent means to conduct and document road sediment analysis. For larger landowners, this framework is an efficient means to handle the complexity and address road sediment delivery on a strategic, tactical, or operational level. For policy-making, this framework is an effective means to evaluate best management practices alternatives.
