This project contains datasets associated with Seaside, Oregon, a multi-hazard testbed for infrastructure resilience. Seaside is located along the Oregon coast and is subject to both seismic and tsunami hazards associated with the Cascadia Subduction Zone (CSZ). The Seaside testbed was established as a multi-hazard testbed for the NIST Community Resilience Center of Excellence. The size of Seaside lends itself to parcel-level analyses of multi-infrastructure damage, loss, and recovery modeling. Datasets are provided for built-, natural-, and social-systems in Seaside. The built environment consists of buildings, electric power, transportation, and water infrastructures. The building inventory was constructed from tax-lot data, Google street view, and a field survey (Park et al., 2017b). The electric power network was constructed from aerial imagery. Bridges in the transportation network are from the National Bridge Inventory and roads are from the TIGER/Line database. The water network is from the city of Seaside public works (Kameshwar et al., 2019). The natural environment (hazards) are the result of a probabilistic seismic-tsunami hazards analysis (PSTHA; Park et al., 2017a). The social systems consist of results from a housing unit allocation (Rosenheim et al., 2019). Researchers, decision makers, and planners, among others, can utilize these datasets to conduct community-scale multi-hazard risk assessment, focusing on application to the coastal urban city of Seaside, Oregon.
