by

King County Wastewater Treatment Division

Feb 4, 2013

Tunneling continues from the south shaft towards the north shaft in Ballard. Beginning February 7, crews will be tunneling from the south site (24th Avenue West and West Commodore Way) up to 24 hours a day, Monday through Saturday. Night activities will allow the tunnel to be completed sooner. Neighbors can expect increased nighttime noise, truck traffic and additional lighting on site until tunneling is complete.

Crews also continue constructing the afterbay structure which will connect the new siphon to the existing sewer system. These construction activities will continue to occur during typical work hours from 7:00 a.m. to 6:00 p.m. weekdays and some Saturdays.

What to expect at the south site:

  • Activity on the project site 24 hours a day, Monday through Saturday
  • High levels of activity involving equipment and trucks
  • Increased night truck traffic around West Commodore Way
  • Additional nighttime noise
  • Additional lighting on site
