Heather Murphy: Cooling the Desert

Hot pavement is a problem in cities across the country. Heather Murphy, Communications and Public Engagement Coordinator at the Phoenix Street Transportation Department, talks about a new pilot program that is now working to cool the city by decreasing the heat of the pavement. The non-toxic treatment that Phoenix is using also contributes to less wear and tear on the underlying asphalt. The innovations in the desert will hopefully spread to other cities that need to reduce heat as the population increases.
