Trees and native plants like the ones in Grant Park are common tools in green infrastructure planning, a way to manage stormwater by replacing cement and asphalt with natural landscapes. Going green is cheaper than using sewers, overflow pipes, and other traditional methods. Plants can trap rainwater and prevent pollutants from city streets from running into waterways. At the same time, green spaces provide food and homes for wildlife, improve soil health, prevent erosion, replenish groundwater supplies, and create beautiful, walkable areas for residents and tourists to enjoy.

Some cities are using green infrastructure to prepare for the effects of climate change. Scientists predict the Midwest will have wetter winters and more frequent extreme events like blizzards, heavy rainstorms, and droughts. Trees and other greenery along city streets can absorb and retain water, which helps cities avoid the worst of droughts and storms and ensures residents have access to a safe, stable supply of water. In Chicago, green infrastructure can also help fight rising temperatures made worse by air pollution and buildings and roads that trap heat. Trees cool the air and provide much needed shade.
