 Roads  Bridges  Passenger rail  Freight rail  Airport  Public Transportation  Bicycle and Pedestrian Asset categories to be considered:

Potential Impacts Insert picture CLIMATE CHANGE EFFECT IMPACTS Higher high temperatures, more hot days Asphalt deterioration, road buckling Thermal expansion of railroad tracks and paved surfaces Changes to biodiversity (impacts pest management, wetlands commitments, endangered and invasive species) Pavement & structural design changes Drought /Lack of precipitation Shrinking clay soil – road damage & water main breaks Loss of vegetation and soil stabilization Changes to biodiversity Increase in wildfires More frequent, intense wind speeds More frequent sign damage, truck rollovers, debris disruptions Power outages, disrupted traffic lights and other electronic infrastructure Disrupted air travel Increase in wildfires More frequent, intense precipitation Loss of visibility, lane obstruction Increased flooding of roads- weather-related delays, traffic disruption influence scour rates - size requirements for culverts Standing water impact on road base Erosion of road base resulting in structural failures Impact on emergency services and evacuation routes

Local Impacts Buckling roads Drought: Disrupted Water Flooding: Tropical Storm Hermine Wildfires High winds Fallen tree Aftermath of wildfire Sinkhole

Asset Categories ImpactImpact-Asset RelationshipsThreshold RailroadsHeat Increases in temperature lead to increased risk of buckling and expansion. 110°F cited as threshold for buckling. At 90°F, rail speed is slowed. Roads and health Heat High temperatures can increase health and safety risk as well as engine and equipment heat stress Health and safety risk as well as possible engine/equipment heat stress begins at around 85°F, but the situation becomes more critical at °F. Roads and Highways Wind High winds cause safety risks and travel delays, a loss of visibility, impaired mobility, loss of communications and power, freight/cargo damage risk, increased risk of collisions/spills of hazardous cargo, and transport schedule delays. Winds become dangerous to road maintenance, truck operations, and other road users at around 39 mph and are very dangerous at 74 mph. AirportsRain An increase in precipitation can impede aircraft traffic and flight departure/arrivals. Heavy rain of 1 to 2 inches per hour. When runway becomes wet from precipitation. InfrastructureDrought A decrease in precipitation coupled with heat can cause clay soils to shrink and disrupt waterlines 40 consecutive days over 100°F without rain may impact water infrastructure Setting Thresholds (Mobile AL. example)

Adaptation Framework

 Risk Assessment  Vulnerability = Exposure, Sensitivity, Adaptive Capacity  Vulnerability Assessment Matrix Adaptation Framework

Challenges and Opportunities  Combining and understanding multiple disciplines  Communicating relevance given varied opinions on climate change in the region  Incorporating results into existing processes and avoiding “just another study on the shelf”.
