<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>A total of 848 bridges were analyzed for their vulnerability to inland flood, coastal flood, and geohazards. This data set is limited to NBI bridges on North Carolina primary roads, Only bridges exposed to at least one natural hazard are included. NBI bridge data was joined to the NCDOT structures data. The combined bridge 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 bridge was intersected with layer representing NCDOT's Geotechnical Asset Management (GAM) database. The sensitivity assessment for bridges was derived from the condition state for structures from Natural Bridge Inventory (NBI) items. For bridges with known foundation where NBI Item 113 Scour Critical is not equal to “U”, a matrix intersecting NBI Item 113 with NBI Item 60 Substructure Condition produced the sensitivity score. 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.</SPAN></P></DIV></DIV></DIV> |
