Description: A total of 1,385 culverts were analyzed for their vulnerability to inland flood, coastal flood, and geohazards. This data set is limited to NBI culverts on North Carolina primary roads, NBI bridge data was joined to the NCDOT structures data. The combined data was intersected with flood data from NCDOT's resilience applications (https://www.ncdot-raft.info/applications.php), i.e., the Roadway Inundation Tool (RIT) 2.0 for inland flooding, and the Coastal Roadway Inundation Simulator (CRIS) for coastal flooding. In addition, each culvert was intersected with layer representing NCDOT's Geotechnical Asset Management (GAM) database. A score for sensitivity was derived from NBI Item 62, Culvert Condition. The final prioritization score is the sum of exposure scores for flooding and geohazards, criticality, sensitivity, whether the bridge overlaps a State Transportation Improvement Plan (STIP) project. For a complete discussion of the resilience analysis and scoring process, see Appendix C of the NCDOT 2023 RIP.
