It's going to get louder; Pile driving begins at Barton Pump Station on Fauntleroy

Expect increased vibration and noise

Information from King County

Starting as early as Wednesday, June 19, crews will need to install additional steel sheet piles in order to complete soil stabilization work at the Barton Pump Station. As crews install the sheet piles, there will be a temporary closure of the north ferry entrance lane and toll booth on Thursday, June 20. The lane is expected to be re-opened by 3:30 p.m. but could extend into the evening commute.

King County will notify commuters and the community if the lane closure extends past 3:30 p.m. on Thursday, June 20. Work is expected to be complete by Friday, June 21.

During jet grouting activities, crews determined that soils in the southwest corner of the site were incompatible with the jet grout. Crews have already installed one set of necessary sheet piles and now must complete the work.

Installing the piles requires the use of a vibrating hammer, which is expected to increase levels of noise and vibration. In an effort to mitigate these impacts, a portion of the pile locations will be pre-drilled and filled with sand. The crew will be closely monitoring vibration levels to minimize disruption to the extent possible.
