Climate Change Impacts:
Property and Infrastructure

Cities and other heavily developed areas are particularly vulnerable to the risks of climate change. This vulnerability is a result of a unique combination of exposure and sensitivity to a changing climate, and the ability of populations to adapt to these changes.

By definition, cities are characterized by a large concentration of infrastructure, buildings, and people. As a result, all these people and structures are exposed to the impacts of climate change. Older buildings and infrastructure, which were built under less stringent building codes, are typically less resistant to extreme weather events, such as extreme heat periods or precipitation and flooding events. The ability of property owners, municipal managers, and city dwellers to adapt to a changing climate largely depends on the financial resources available to them. The costs of adapting will rise with the magnitude of climate change, straining the resources of the many segments of society and municipalities. Among the potential impacts with implication's for property and infrastructure in Wisconsin are:

  • Increased Frequency of Heavy Rainstorms
    Climate change models for the Great Lakes region project an increase in the frequency of heavy rainstorms—both 24-hour and multiday—over the course of the century. More frequent heavy rainstorms will likely lead to more floods, exacerbated by stream channeling and more paved surfaces. This could result in greater property damage, place heavier burdens on emergency management, increase cleanup and rebuilding costs, and exact a financial toll on businesses and homeowners.

  • Increased Frequency of Flooding
    Wisconsin FloodAn increase in the frequency of storms, and flooding in particular, could overwhelm municipal water-related infrastructure. Therefore, municipalities in Wisconsin will have to upgrade water-related infrastructure—including levies, sewer pipes, and wastewater treatment plants—in anticipation of a changing climate.

  • Decreased Lake Levels
    Low LakesDespite more frequent heavy rain events, lake levels are expected to drop due to higher rates of evaporation. Lower lake levels will have costly implications for shipping and other economic activities on the Great Lakes. A drop in lake levels would require more frequent dredging of channels and harbors as well as adjustments to docks, water intake pipes, and other infrastructure. On the other hand, a longer ice-free season will extend the shipping season.
