Integrating Assets Vulnerable to Sea Level Rise and Extreme Weather Events into Ongoing Structural Review Decisions at MaineDOT

Maine Department of Transportation (MaineDOT) has identified coastal bridge and culvert features along its coastal assets that are vulnerable, sensitive, and critical according to a range of technical, environmental, bureaucratic, and economic risk metrics. For the most critical assets it has then identified which engineering designs would be good investments given extreme weather scenarios in both coastal and inland areas, across possible environmental futures. The current project goes farther, using geographic information systems (GIS) to incorporate lessons from these efforts into ongoing asset management so that similar benefits can accrue to larger numbers of vulnerable assets on an ongoing basis. The authors report on (1) a GIS overlay method developed to be easily communicable between DOT programs and replicable each year as part of developing the next work plan iteration and (2) efforts to use results from the method to identify immediate and longer term actions to enhance resiliency of vulnerable road segments, bridges, and culverts. Lessons are drawn about fitting such targets into existing agency processes, satisfying federal requirements for risk-based asset management, and taking advantage of existing expertise.
