Hamilton Avenue Street Closure, 12/16 – 12/17

Good afternoon,

Hamilton Avenue will be closed from east of Surveyor Circle to the Magnolia Street intersection from 8:30 a.m. – 3 p.m. on Tuesday, December 16, and Wednesday, December 17, 2025. This street closure is needed to complete pavement restoration on Hamilton Avenue for DTSC-approved work related to stormwater pipe installation. During this work, traffic control personnel will be supporting traffic, as needed. We apologize for this inconvenience. This work is critical to complete the final cleanup of the Ascon Site. You can learn more about the Ascon project and work at asconhb.com.

Thank you for your patience during this work. If you have any questions regarding the stormwater pipe installation, please contact the Ascon community information line at 714-388-1825 or email the project team at info@asconhb.com.

Thank you,

Ascon Project Team
