Combating Heat Stress: Why Schools Are Replacing Asphalt Playgrounds
Schools across the U.S. are transforming their asphalt-covered playgrounds into safer, cooler spaces by planting trees, building shade structures, and adding rain gardens. The Trust for Public Land is leading this effort, especially in urban areas where extreme heat poses a greater risk. Research shows that asphalt surfaces can reach dangerously high temperatures, turning schoolyards into hazardous "heat islands."
States like California and districts such as Los Angeles Unified are investing billions in these greening projects to reduce the risks of heat-related illnesses among children. However, funding disparities and maintenance concerns remain challenges for many districts. Advocates hope these changes will set a precedent for safer play areas nationwide.
