Permafrost underlies approximately 20% of the landmass in the Northern Hemisphere. Inevitably human infrastructure has been and will be built on permafrost; however, due to climate change, the permafrost in many regions has begun to thaw. Using past reports and surveys as guidance, a survey was conducted to track the effects of permafrost thaw on housing infrastructure in the community of Point Lay, Alaska. The Cold Climate Housing Research Center, Inc. and the National Renewable Energy Lab conducted a literature review and interviews to document community issues from thawing permafrost and identify potential mitigation strategies for existing and new infrastructure. Researchers also identified strategies for individual homeowners to inspect their foundations for current issues or anticipate future ones. This poster will cover the results from the survey on the effects of permafrost thawing to Point Lay and include permafrost basics, common concerns from thawing permafrost, steps to identify permafrost sites and visible signs of permafrost degradation, and potential mitigation strategies that may be beneficial to Alaskans and increase resilience in the Arctic.

Permafrost is ubiquitous in the Arctic and Antarctic, and present in high elevation regions throughout the world. The communities and industrial development in permafrost regions require transportation infrastructures (roadways, airports, railways, etc.) and, in these regions, transportation is of vital social, economic, and political importance (Regehr, Milligan, and Alfaro 2013). However, warming climate conditions will endanger existing and future transportation infrastructure in Alaska to the tune of $282 to $550 million (2015 USD) depending on future emission scenarios (Melvin et al. 2016). Given these conditions, tools are required to aid decisionmakers in prioritizing infrastructure maintenance, replacement, and construction, and potentially justifying the use of mitigation strategies of permafrost embankments. Risk analysis methods can be used but their existing application to permafrost engineering is limited. Risk is a product of hazard, consequence and vulnerability for each of the dangers under consideration. The probability and costs of a danger's occurrence is a hazard and the consequence, respectively, while vulnerability correlated the damage with the consequence. Since little failure data is available for permafrost infrastructure, the hazard must be determined from reliability analysis methods (First-Order Second-Moment or Monte Carlo Simulation), which aggregate the uncertainty of input parameters to determine the result's variation. These methods require the characterization of random variable uncertainty, which can be difficult without sufficient data, often more than the current standard-of-practice. Additionally, the method requires a limit state function for the danger to be analyzed. Common dangers effecting permafrost embankment infrastructure included: settlement, cracking, sudden collapse, lateral embankment spreading, drainage and ponding water, and active layer detachment landslides. Of these dangers, only a few have existing limit state functions or have limit state functions that can be developed by the author. The dangers with limit state functions or hazard functions include: total and differential thaw settlement, particle position bridging over voids, active layer detachment landslides, and culvert gradient and structural failure. A Microsoft Excel-based program was created to calculate the risk for permafrost embankment linear infrastructure, using statistical methods applied to limit state functions to determine hazards for common permafrost dangers, estimated direct costs for the repair of a hazard's occurrence, and scaling factors to account for the indirect costs of damage to the infrastructure's users and connected communities. Hazard calculations are based on geotechnical property and climate uncertainty, as characterized by probability density functions, using Monte Carlo Simulation methods. A climate change fragility analysis recalculates the hazard with warming air temperatures. Repeated analyses along the infrastructure provide a risk profile of the infrastructure, now and with a warming climate. The program is used to determine hazard for the Airport Access Road in Salluit, and hazard, risk and cost/benefit assessments were conducted using this program for the Iqaluit International Airport.
