Support and participate in community-driven programs for green initiatives. Work with your community to increase urban trees and vegetation to create an expanded urban tree cover, which is vital for cooling cities, managing water, improving air quality, and decreasing stress. And did you know asphalt heats up faster than bare ground? Depaving has a number of benefits including decreasing water pollution, increasing green space and thereby cooling surrounding areas, improving air quality, and reducing flooding. Install permeable pavers. These are made up of a layer of concrete or fired clay brick. The pavers are separated by joints filled with crushed aggregate. Rainwater passes around the paver and percolates into the ground, thereby recharging groundwater.
