Phoenix FAQ
Can I request cool pavement on my street?
Phoenix accepts requests through the Street Transportation Department, but selection prioritizes heat-vulnerable zip codes flagged by the Heat Action Plan rather than first-come scheduling. Council district offices can advocate for neighborhood streets.
Is cool pavement required for new parking lots?
No. Phoenix does not mandate cool surfaces for private parking lots. The Phoenix Green Construction Code awards voluntary points for cool-pavement materials in commercial developments seeking enhanced certification.
How long does the coating last?
Phoenix's reflective sealcoat lasts roughly 6 to 8 years before reapplication. Performance is monitored through pavement-management audits in treated corridors, with ASU partners tracking surface temperature data over time.
