It is important to place the trees strategically, so they don’t block storefronts and signs, and won’t damage surrounding infrastructure as they grow. This approach will prioritize the long-term health of the trees and your community’s investment in establishing a vibrant urban canopy, as well. Advocate for tree-friendly regulations like St. Petersburg, Florida, which requires that Community Redevelopment Districts (including two Main Street districts: EDGE District and Deuces Live) have a minimum of one shade tree every 200 square feet along walkways and pedestrian connections.
Smaller plants can also help reduce the urban heat island effect. Just grass alone can have a significant cooling effect: research has found that they can make areas 2 degrees cooler. As with trees, make sure to select smaller plants that are appropriate for your district’s climate and sites — consider reaching out to your local nursery or master gardener association for recommendations on grasses, shrubs, succulents, and bushes.
If your sidewalks are already well-landscaped with plants, consider expanding your greenery cultivation sights to the rooftops. Green roofs have many benefits, including stormwater management, reduced cooling costs, and beautification. Rooftop vegetable and pollinator gardens can serve a dual purpose in producing food for humans and beneficial insects alike. Learn more about green roofs here.
Splashing Out
Whether you are dipping your toes in or simply standing nearby, water has amazing cooling effects. Adding water to your downtown, or taking advantage of existing waterways, is a great way to mitigate the heat.
If your district is near a river, lake, beach, or other water source, consider building strong connections between it and the downtown core. For example, the Skowhegan River Park in Maine is transforming the nearby industrial downtown river corridor into an accessible outdoor area with a trail network and other recreational opportunities. Strengthening connections between downtown and nearby waterways helps people escape the heat while still engaging with your district.
Artificial water features are another great option. Splashpads are a fun way for children, animals, and adults to cool down. Connecting these features with public art or other placemaking installations ensures that they fit seamlessly with the character and style of your Main Street. Fountains can also help cool the air while also creating a space for people to gather. Misters can offer a smart solution cooling effect in districts, especially those located in arid regions where water conservation is a priority.
Seemingly basic civic infrastructure, such as public restrooms and water fountains, serve important roles in helping people beat the heat. Public restrooms provide places of rest and respite from the sun, as well as fresh water to rinse faces or prepare cool compresses. Water fountains, bubblers, and water bottle filling stations provide clean drinking water essential for helping people stay cool and hydrated.
