Per Montgomery County: The results of the 2022 Montgomery County “Urban Heat Island Mapping Campaign” document that neighborhoods with less green infrastructure and more concrete experienced temperatures up to 10 degrees higher than nearby cooler areas. The County’s Department of Environmental Protection (DEP) released the results of the campaign in partnership with the National Oceanic and Atmospheric Administration (NOAA) and Climate Adaptation Planning and Analyst (CAPA).
A StoryMap created by DEP provides a comprehensive overview of the campaign. Among its findings were that areas with low-income households and people of color have higher temperatures than other areas in Montgomery County due to a lack of green spaces and trees, indicating that extreme heat is a social justice issue.
