An urban heat island (UHI) is an urban area that is significantly warmer than its surrounding rural areas. Modified land surfaces (paving, sidewalks, streets, etc.) in the urban environment retain heat and are the main cause of UHI.
In Fredericksburg, the UHI is strongest in the summer months. When combined with summer weather, the UHI can create periods of extremely high temperatures and humidity levels that have serious health impacts on vulnerable members of our community (people with asthma and pulmonary conditions, the elderly, etc.). As extreme heat events increase with climate change, the urban heat island is projected to intensify.
How do higher temperatures from urban heat islands impact our community?
Negatively affect our health and comfort
Elevate level of air pollutants and greenhouse gas emissions
Higher energy bills
Increase energy consumption in buildings
Impair water quality
What can you do to reduce the impact of UHIs?
Plant trees or care for trees in your neighborhood
Install a vegetated or green roof
Create a green space on vacant land or help maintain an existing green space
Install permeable surfaces on roadways, sidewalks, parking lots, and alleys
Stay Cool and Safe!
