• Abstract:
  In July 2016, the Oregon Department of Transportation (ODOT) was awarded a Federal Highway Administration (FHWA) grant to analyze how green infrastructure, or nature-based infrastructure, can help protect the Oregon Coast Highway from the impacts of extreme storms and coastal bluff erosion. This study builds upon prior ODOT research on dynamic revetments, also known as cobble beaches or berms, and incorporates lessons learned from similar projects. Results from the study include a set of conceptual design plans for three high-risk sites. More detailed analysis of the preferred designs was conducted and includes anticipated protection against future coastal impacts, estimated construction and maintenance costs, and implementation benefits and challenges. A goal of the study was also to collaborate with regulatory and resource agencies and on the design options that could be permitted and constructed under current rules and regulations. The options developed and our outreach with stakeholders will help inform and guide decisions for how we address these and similar sites vulnerable to coastal hazards in the future. The project was co-led by the ODOT Sustainability Program and Region 2 Technical Center in Salem, Oregon.
