The Massachusetts Department of Environmental Protection (MassDEP) and the Massachusetts Office of Coastal Zone Management (CZM) have identified the position of ocean-facing coastal banks over the last 30 years and estimated coastal bank erosion over time. In addition to the coastal bank position in the MassDEP Wetlands data layer, top of coastal bank delineations are now available for multiple time periods between 2000 and 2014. High-resolution elevation data (LIDAR) and historical aerial photography were utilized for the project. The data were developed to identify the magnitude of coastal bank erosion and location of hotspots, and inform planning and policy efforts. The presentation and discussion focus on the coastal bank erosion hazard data and its application.
