Inventory of the Physical Infrastructure at Risk of Flooding due to Climate Change-Induced Sea Level Incursion in Three Nova Scotian ACAS Communities

Development of climate adaptation strategies, and subsequent decisions on which are the best options to pursue, require a quantifiable understanding of the infrastructure that is at risk due to flooding and sea level rise. Infrastructure is the physical plant of public services in the communities, as well as privately owned built structures. Public infrastructure can include transportation structures (e.g. roads, wharves, bridges, causeways, parking sites, etc), utility structures (e.g. power lines, rail tracks, pipelines), public service buildings (e.g. hospitals, fire halls, police and emergency service buildings, community centres, etc), and recreation structures (e.g. buildings, trails, parks). Private infrastructure can include residences, commercial and industrial buildings and associated facilities, places of worship, among other structures. From a climate adaptation planning perspective there is a need to identify the infrastructure in municipalities that is at risk of inundation by coastal flooding under different sea level rise and storm surge scenarios., To inventory and identify infrastructure in the ACAS study areas of the Town of Yarmouth, the Municipality of the District of Yarmouth and the Municipality of the District of Lunenburg that is at risk of inundation by coastal flooding under different sea level rise and storm surge scenarios, Reports for each community, detailing the site characteristics, project method, results, discussion of findings and conclusions. Maps showing the spatial distribution of infrastructure in the communities, and intersection maps that show infrastructure potentially impacted by climate change under different flood scenarios currently and into the future. Data sets that may be developed as a result of the work (in digital format)., The project will contribute to the development of methodology and approaches by which impacts on infrastructure can be assessed by municipalities in Nova Scotia. The analyses will contribute to additional analyses that assess social and economic impacts of climate change in the target areas. The project will contribute to the training of professional human resources who are competent in conducting similar analyses elsewhere.
