Key Facts

Lead agency: SCC Roads and Airports
Surface temp drop: 10 to 15 degrees Fahrenheit
Pilot communities: Heat-vulnerable unincorporated pockets

Summary

Santa Clara County Roads and Airports runs limited cool pavement pilots in heat-vulnerable unincorporated communities like East San Jose foothill fringes. Reflective coatings reduce surface temperatures by roughly 10 to 15 degrees Fahrenheit on summer afternoons aligned with OneSCC heat equity goals.

Full Breakdown

Santa Clara County Roads and Airports has piloted solar-reflective pavement coatings on selected residential streets in heat-vulnerable unincorporated pockets, including stretches near East San Jose, Alum Rock fringes, and South County agricultural-edge neighborhoods. Coatings raise surface albedo from typical 0.05 for fresh asphalt to 0.30 or higher, lowering peak surface temperatures by roughly 10 to 15 degrees Fahrenheit. Pilots align with the OneSCC 2030 Sustainability Master Plan and county climate adaptation work prioritizing low-income and BIPOC neighborhoods identified in vulnerability mapping. Roads monitors durability and air-temperature effects before scaling. Residents face no permit obligation since coatings are applied by county crews under standard street-maintenance budgets.

Violations & Fines

Cool pavement is a county capital project, not a regulatory mandate, so private property owners face no fines or permits. Driving on freshly coated streets during the cure period without following posted detours can draw a standard traffic citation.

Frequently Asked Questions

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.
