Key Takeaways

Arizona Threats Are Increasing

Temperature rises, floods and wildfire occurrences are exacerbating the risks to critical roads.

Adaptations Will Be Costly

Adapting roads to be resilient to extreme events will significantly increase project costs.

Transportation Faces New Concerns

The overall road networks will face new issues as combined threats increase the types of risks that exist.

About the Project

Enhancing SR-88's Resilience Against Wildfire and Flood Risks

Arizona is experiencing increased wildfire and flood risks due to extreme climate events. SR-88 is a key recreation access route in the northern part of the state. After several washouts due to extreme storms and wildfire, the state wanted to establish greater resiliency for the redesigned highway. A component of that resilience is understanding key threats to the road and the potential for these threats to occur.

Resilient Analytics was the climate consultant in this effort to determine the physical risk due to changes in wildfire and extreme precipitation events. The team was tasked with delivering risk evaluations for the highway, as well as providing potential changes in design criteria to the Stanley Consultants design team. The intent of this project was to reduce the chances in the future of the road being closed.

Resilient Analytics utilized its core Infrastructure Planning Support System technology to analyze the potential for severe damage over the next 20 years. The team focused on an in-depth analysis of the highway and its resilience to potential rockslides, wildfire and flood from the surrounding area. The team delivered a report to the design team detailing the risk to the highway and recommended design conditions that should be considered.
