Two weeks after a Seattle Public Utilities contractor started night work cleaning sewer/storm lines at the Fauntleroy ferry dock, SPU has announced an extension: “The concrete slurry found in the pipes is a higher strength than we had expected. Therefore, the contractor will discontinue with the jet and hydro cleaning efforts and move to a milling process to grind the slurry from the pipes. The equipment and noise levels will remain the same as before.” Part of the north ferry-loading lane will continue being coned off while this work is done. It’s now expected to continue 9 pm-5 am through January 30th.
