 Cool Pavement Coating at San Juan and San Leon 

The City of Irvine is implementing an innovative pavement coating pilot program that extends
the life of City streets while helping to reduce heat from the ground up.

The City’s Public Works & Sustainability Department will apply DuraShield Solar Reflective Grey pavement coating on San Juan and San Leon Monday, August 5, through Friday, August 9, between 8 a.m. and 4 p.m. Work is weather permitting.

This unique coating, which is grey in appearance, has pavement preservation characteristics similar to slurry seal and offers numerous benefits for the community. Irvine is the first Orange County city to apply the solar reflective pavement.
