Annual Slurry Seal Project: Zone D


Slurry Seal, Zone D: This project is part of the City’s Annual Slurry Seal Program funded through the CIP and includes localized pavement repairs, crack sealing and slurry sealing. Zone D includes the residential & commercial areas north of Lake Forest Drive and East of Trabuco and West of the SR-241 Toll Road. Click on the image to the right to view a map of all Slurry Seal Zone sites.

The contractor is currently completing localized pavement repairs and crack sealing. Notifications for the start of slurry sealing were sent out the week of August 14, with slurry operations beginning on Thursday, August 24. In order to minimize disruptions, slurry sealing will occur in residential areas on Thursdays, Fridays and Mondays, and in commercial areas on Saturdays and Sundays.

This schedule will allow the slurry more time to cure in advance of the weekly trash pickup on Wednesdays in this area. Slurry sealing usually requires residents and property owners to avoid driving on the street for approximately 8 hours. This project is expected to be completed by the end of September.
 
For any questions please contact Rina Adjoian Der Alexanian, Principal Engineer, (949) 461- 3490, or Douglas Erdman, Engineering Manager/Assistant City Engineer (949) 282-5233
