The King County Wastewater Treatment District says the Monday morning “storm surge” caused some minor damage at the Barton Pump Station expansion project north of the ferry dock. Crews repaired the chain-link fence and concrete barrier blocks, according to a news release:

The storm washed waves and driftwood through the barrier into the construction site. The repaired barrier includes an additional row of concrete blocks to protect against future storm events.

Crew members were on site Sunday to prepare for the approaching storm. All on-site liquids were properly stored and materials from the jet grouting operation were cured. There was no contamination of any materials into Puget Sound.

Crews will continue to monitor site conditions through the winter storm season and will take precautionary measures as needed to protect both the site and Puget Sound.

The construction work is scheduled to continue until late 2014.
