Field work at the Ascon Landfill Site during the week of March 9, 2026

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

An offsite odor monitoring technician, in an Ascon-labeled orange safety vest, monitors outside the Site on days of onsite excavation in areas with a higher potential for odor. To answer community questions, the Ascon information table will be set up in Edison Park across from the Site on days of active excavation in areas with a higher potential for odor.

During this phase of work, personnel may be onsite on Saturdays to conduct Site work and equipment maintenance from 7 a.m. to 5 p.m.

Upcoming Clean Soil Import Work

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

• As many as 100 import trucks may arrive onsite per day. ​
• Work may occur Monday through Friday, between 7 a.m. and 6 p.m.
• Haul trucks enter Ascon from Hamilton Avenue and exit on Magnolia Street. Import haul trucks avoid the major intersection of Hamilton and Magnolia per the project’s approved haul route plan.  ​
• Dust mitigation and traffic control measures are in place during this clean soil import, including continued onsite dust mitigation measures. We also conduct additional street cleaning outside project site entrance and exit areas.​
• Approximately 11,000 CY of clean soil will be brought onsite during this upcoming import. Additional clean soil import work will occur in the future.

Magnolia Street Storm Drain Connection Work

Ascon will conduct infrastructure work to connect to the City’s storm drain that is located on the western side of Magnolia Street outside of the Site. This work was paused due to recent weather events in the area and is scheduled to resume the week of 3/16, dependent on weather and Site conditions.

Here is what you can expect to see:

• This work is expected to take approximately 3 to 4 weeks to complete, dependent on weather. Lane closures may occur for 1 to 2 weeks intermittently during this period.
• Traffic and bike lane closures may occur from 8:30 a.m. to 3 p.m., as needed, and will be limited to the southbound outer traffic and bike lane.
• A portion of the barrier wall between the Ascon Site and Magnolia Street will be removed and replaced with temporary chain link fence during this work. The barrier wall will be restored upon completion of this work.
• Traffic control equipment and personnel will be present to support traffic, as needed. One southbound lane will remain open for traffic during this work.
• To answer community questions, the Ascon information table will be in Edison Park during the Magnolia Street lane closure work.
