Weekend Work Scheduled for Lowman Beach Retention Tank Dirt Removal

IMG_1610Contractors for King County Wastewater Division will be working on weekends this month to remove the dirt from the million-gallon retention tank being constructed at Lowman Beach Park as part of the Murray Basin Combined Sewer Overflow project.

To keep the project on schedule and avoid digging during heavy rains, King County’s contractor will work Saturdays in October. Saturday work will begin at 9:00 am and finish at 6:00pm. The County contractor expects to finish digging out the tank area by early November, before the largest winter storms usually arrive. Digging during storms takes longer and increases the chance of mud from the site getting on to streets and storm drains.

What to expect on Saturdays:

  • Upcoming Saturday work days:
    • October 4
    • October 11
    • October 18
    • October 25
  • Work hours from 9:00 am to 6:00 pm  (Weekday work hours continue to be 7:00 am to 6:00 pm)
  • Noise from trucks and excavators, including backup alarms
  • Excavators, pumps, and trucks working on and near the site
  • Up to 55 trucks entering and leaving the site each day (about 7-8 trucks per hour)
  • Flaggers to keep traffic moving as trucks access the site
  • No parking on the eastern side of Beach Drive SW
  • Limited parking on the western side of Beach Drive SW
  • Limited access to the eastern sidewalk on Beach Drive SW
  • Beach Drive S.W. and Lowman Beach Park remain open
  • Primary haul routes remain Lincoln Park Way and 48th Ave SW
  • The sound of running water may also be noticeable. Groundwater is being pumped from the tank area into a holding tank on site to allow for safe digging. The sound you may hear is typical for this kind of work.
