Los Angeles FAQ
Can I request CoolSeal on my street?
Residents can submit requests through Council District offices or MyLA311. Selection prioritizes disadvantaged communities and heat-island intensity scores from CalEnviroScreen rather than a first-come basis.
Is cool pavement required for new parking lots?
Not by Los Angeles ordinance. CALGreen Title 24 Part 11 §A5.106.11 offers voluntary credit for cool surfaces in nonresidential parking, and LEED Sustainable Sites credit also applies.
How long does CoolSeal last?
The coating typically lasts 6 to 8 years before reapplication, similar to conventional sealcoat. StreetsLA tracks performance through pavement-management audits in treated CoolStreets corridors.
Norwalk FAQ
Can I request cool pavement on my street?
Submit a request through LA County Public Works at 800-675-HELP. Crews prioritize streets in Heat Equity Zones identified by the Climate Vulnerability Assessment. 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 31 Green Building Standards encourage but do not require reflective driveway surfaces.
