To increase ecological and social resilience to climate impacts, Washington State has shifted from conventional flood mitigation measures, such as engineered infrastructure, to process-based (PB) restoration, which promotes multiple-benefit solutions that encourage the integration of ecological and social systems. Widespread funding opportunities for local PB restoration projects have led to the reconnection of thousands of acres of floodplains, restoration of countless miles of salmon habitat, preservation of immense swaths of farmland, and removal of thousands of at-risk properties from Washington’s landscape. However, as PB restoration programs scale up projects, success hinges on streamlined regulatory processes. In addition, the lack of standardized ecological and social monitoring measures makes it impossible to define overall success of PB restoration programs. It is important that these measures are addressed so additional communities can reap PB restoration's widespread ecological, social, and economic benefits.
