Emergency Infrastructure Stabilization and Resilience Response Following Hurricane Helene-PPT Presentation

PPT Presentation

Pdf Summary

Hurricane Helene made landfall in Florida on September 26, 2024, as a Category 4 storm, then caused catastrophic damage across the southeastern United States. The presentation reports at least 227 deaths, initial damage estimates of $80 billion, up to 30 inches of rain in some areas, more than 2,000 landslides, and damage to or destruction of about 7,000 roads and bridges.<br /><br />In western North Carolina, the storm severely affected I-40, a key transportation route carrying more than one million people daily. Lidar analysis indicated that roughly one million cubic yards of material had been lost near the Tennessee–North Carolina border. Restoring even partial highway capacity required urgent stabilization of the remaining roadway.<br /><br />GeoStabilization International began responding in early October 2024 and expanded from four crews to 28 by mid-November, using a triage approach. Response work faced major logistical obstacles: outages, limited lodging and cell service, closed roads, and shortages of materials. Field conditions were also difficult, including unstable shot rock, hidden voids, active drainage, cold and wet weather, and uncertain excavation quantities. Coordination among crews, contractors, and transportation agencies was essential for safety, scheduling, and documenting cost overruns.<br /><br />The presentation describes several storm-related failure types—including embankment failures, scour-induced slides, debris flows, and rockfalls—and reviews typical transportation-department repairs and additional examples. It concludes that the frequency and intensity of such events are increasing, underscoring the need for resilient infrastructure and rapid emergency-response capacity.
