U.S. DHS Casco Bay Region Climate Change Resiliency Assessment

As a part of the Department of Homeland Security (DHS)’s Regional Resiliency Assessment Program (RRAP) - this research focuses on the local and regional impacts of climate change in the Casco Bay area, the most developed and populous region in Maine. The report focuses primarily on vulnerabilities that may affect the region’s ability to maintain its critical infrastructure systems, and provides corresponding Resilience Enhancement Options that DHS and other partners may utilize in climate adaptation planning.

The RRAP is a cooperative, non-regulatory, DHS Office of Infrastructure Protection (IP) led assessment of specific critical infrastructure, and regional analysis of the surrounding infrastructure. IP identified the critical lifeline infrastructure systems - Water Resource Systems; Energy Systems; Transportation; and Telecommunications - in the Casco Bay region as the focus for one of 10 RRAP projects conducted nationwide in 2014. The Casco Bay RRAP is the first in the history of the program to focus on climate change and provide information and methodologies to stakeholders to enable regional climate change adaptation planning. 

Climate change impacts on the four critical infrastructure systems analyzed in the Casco Bay RRAP (energy, transportation, water/wastewater, and telecommunications) were identified through stakeholder workshop discussions and infrastructure analysis. The results of the impact assessment for these systems are detailed in the report, and Key Findings are summarized.   

Based on the Key Findings from the assessment process, Resilience Enhancement Options were developed and are described along with the findings. 

Some of the Resilience Enhancement Options detailed in the report include the following:

  • Form an integrated planning body to address the impacts of climate change at the regional level
  • Work with Federal partners to model future climate change impacts on infrastructure and develop adaptation strategies
  • Conduct an assessment of critical infrastructure dependencies to develop a better understanding of potential cascading impacts due to climate change

Along with the resources identified in the individual Key Findings, the report describes additional sources for funding or assistance for implementing the Resilience Enhancement Options.
