DID YOU KNOW?

Clean soil will be brought onsite for future use starting the week of July 28, 2025. This clean soil import work includes transporting a total of approximately 40,000 cubic yards of clean soil onsite through an approved truck route (pictured below) with dust, dirt and traffic mitigations in place to minimize inconvenience to the community. By importing clean soil sooner than originally planned we hope to potentially shorten the overall project schedule.

SITEWIDE ACTIVITIES

  • FIELD WORK: Excavation work will continue in the northern and eastern areas of Ascon this week, depending on weather and Site conditions.

    Here is what you can expect to see during clean fill soil import work:

    • As many as 100 trucks will arrive onsite per day. Work is planned for Monday through Friday, between 7 a.m. and 6 p.m. for four to eight weeks. Work may occur on Saturdays, if needed.
    • Trucks will enter from Hamilton Ave. (green arrow on map) and exit on Magnolia St. (orange arrow on map). Trucks will avoid the major intersection of Hamilton and Magnolia per the project’s approved haul route plan.
    • The Ascon team will monitor soil import trucks to ensure drivers follow the approved route, and we will address any variance from the approved route. Dust mitigation and traffic control measures will be in place during this clean soil import, including continued onsite dust mitigation measures. We will also conduct additional street cleaning outside project site entrance and exit areas.

    The Ascon information table will be set up in Edison Park across from the Site on days that northern excavation and initial clean soil import work is occurring. Offsite odor monitoring technicians, in Ascon-labeled orange safety vests, will be monitoring outside the Site.

    During this phase of work, personnel may be onsite on Saturdays to conduct Site and equipment maintenance, from 7 a.m. – 5 p.m. No excavation work is planned to occur during this Saturday maintenance work.

  • INSPECTIONS:

    • DTSC is the lead regulatory agency for the Ascon project and conducts inspections at Ascon. Their inspection reports can be found on the online DTSC database, Envirostor.
    • The City of Huntington Beach continues its regular stormwater inspections of Ascon. Ascon remains in compliance with stormwater pollution prevention requirements.
    • Regular inspections are conducted by Orange County Mosquito and Vector Control District of areas of the Ascon Site where water may be detained. Active mitigation measures are implemented by Vector Control to protect the community, as well as onsite workers, from mosquitoes.
