The City of Denver is removing heat-trapping asphalt and replacing it with green infrastructure to cool urban heat pockets [1, 2].
This initiative targets neighborhoods that lack sufficient shade, where pavement absorbs and radiates heat. By reducing the amount of asphalt, the city aims to lower local temperatures and improve how the urban environment manages storm water [1, 2].
The program is led by the Department of Transportation and Infrastructure [1, 2]. Officials said they are prioritizing the installation of tree canopies and other vegetated surfaces to replace the hot pavement. These green alternatives provide natural cooling and help prevent flooding during heavy rains by absorbing water that would otherwise run off concrete surfaces [1, 2].
Urban heat islands occur when dense concentrations of pavement and buildings cause cities to be significantly warmer than surrounding rural areas. This effect is often most pronounced in lower-income neighborhoods where tree cover is sparse, a disparity the city is attempting to address through these targeted removals [1, 2].
By integrating storm-water-managing infrastructure, Denver is attempting to solve two environmental challenges simultaneously. The transition from gray to green infrastructure reduces the thermal mass of the city while creating a more resilient drainage system [1, 2].

This shift toward 'depaving' reflects a growing trend in urban planning to mitigate the urban heat island effect. By focusing on shade-deficient neighborhoods, Denver is addressing both environmental sustainability and public health equity, as green canopy cover directly reduces heat-related stress for residents in vulnerable areas.
