Climate Adaptation 

Contaminated Sites




Adaptation Work:

Precipitation has increased 25% in the last 30 years in Ann Arbor and the frequency of extreme storm events has increased 43%. Climate experts agree that climate change is already occurring and the impacts are likely to increase in the future. The City of Ann Arbor recognizes the serious threats that climate change poses to the local environment, economy, and livelihoods and is taking steps to prepare for these unavoidable climate changes.

Undertaking both adaptation and mitigation efforts will make Ann Arbor most resilient to climate changes. For example, building rain gardens and harvesting rainwater on-site is an adaptation technique that facilitates a reduction in flooding during storm events. This action also saves energy by reducing the need to pump water, which is a long-term mitigation technique. Ann Arbor's Climate Action Plan, adopted by City Council in December 2012, identifies both adaptation and mitigation strategies for the city.

According to Great Lakes Integrated Sciences and Assessment (GLISA), Ann Arbor is expected to experience a variety of impacts to its current climate. Expected impacts include:

  • Warmer average temperatures
  • Warmer low and nighttime temperatures
  • Shorter winters
  • More total precipitation
  • More severe precipitation events
  • More extreme heat and drought


Community Climate Partnership

The Ecology Center, the Huron River Watershed Council, the City of Ann Arbor, along with a growing list of other partners launched the Community Climate Partnership to implement Ann Arbor's Climate Action Plan

Urban and Community Forestry Management Plan

The current urban and community forestry management plan underdevelopment will help increase the quality and size of the urban and community forest, which is an adaptive strategy to improve water quality and limit flooding by mitigating storm water runoff
