Special design parameters must be considered for these structures if they are located in the WA-TDZ. Further, the code requires the use of WA Department of Natural Resources (DNR) Tsunami Inundation Data for design purposes, or that such data be considered as a baseline for self-conducted studies. Please consult the 2021 Washington State Building Code for official language.The data provided in feature class were derived from merged datasets from several tsunami hazard publications for the Cascadia Subduction Zone. For detailed methodology and metadata please refer to the source publications listed below. In July of 2024 this feature class was revised per the lineage process description to more closely match the source publications.Source PublicationsAllan, J. C.; Zhang, Joseph; O'Brien, F.
