San Jose FAQ
Can I apply cool coating to my private driveway?
Yes. Private cool-pavement coatings are sold at hardware suppliers and require no permit if applied at grade with no drainage changes. Check manufacturer specs for asphalt compatibility and curing time.
Where can I see installed cool pavement in San Jose?
Public Works publishes a pilot map on the Climate Smart San Jose adaptation page. Demonstration blocks have been completed in East San Jose, with additional sites planned in heat-vulnerable Council District 5 and 7.
Sunnyvale FAQ
Can I request cool pavement on my street?
Submit a request through Santa Clara County Roads and Airports. Crews prioritize streets in heat-vulnerable equity zones identified by OneSCC mapping. Most flatland residential streets outside those zones are not eligible currently.
Does the coating affect my driveway?
No. Cool pavement is applied only to publicly maintained roadways. For private driveways, owners can buy reflective sealants at home stores. Title B Green Building amendments encourage but do not require reflective driveway surfaces.
