Addressing the urban heat island, a quality-of-life issue in a desert environment, was key to the development of the City of Phoenix’s Cool Pavement Pilot Program. During the summer of 2020, Phoenix completed a project by installing an innovative asphalt seal coat technology that could provide meaningful relief from the urban heat island affect. This technology first tried by the City of Los Angeles, CA, reflects solar energy and reduces the daytime pavement surface temperature. The pilot resulted in 36 miles of Cool Pavement treatment in eight neighborhoods and one city park; all with the potential to improve comfort and livability in Phoenix.
