Tucson's Department of Transportation and Mobility runs a cool-pavement pilot applying reflective coatings to selected residential streets to lower surface temperatures, with no homeowner obligation to retrofit private driveways.
Building on CAAP heat-mitigation actions, Tucson DTM has piloted high-albedo coatings on residential streets in heat-vulnerable neighborhoods, monitoring surface and air temperature changes. The program is voluntary and city-funded; private property owners are not required to apply cool coatings to driveways or parking lots, though the UDC encourages light-colored hardscape and shaded surfaces in new commercial sites. Reports are coordinated with the Office of Sustainability and University of Arizona researchers, and findings feed into future paving specifications.
No private fines apply. Damaging or defacing a city cool-coated street section can trigger right-of-way restoration costs under the standard Tucson Code Chapter 25.
