Barton Street Pump Station upgrade project

Frequently asked questions

These frequently asked questions are also available to download as a PDF file (May 2012).

What is the Barton Pump Station Upgrade?

This project will protect Puget Sound and the surrounding environment from sewer overflows. It will increase the pump station’s capacity from 26 million gallons per day (mgd) to 33 mgd – enough capacity to meet West Seattle’s needs through 2060.

The Barton Pump Station, built in 1958, is an underground wastewater conveyance facility located next to the Fauntleroy Ferry Terminal. Upgrades will include a new underground vault to house a standby generator and odor control system; an underground valve room; new underground equipment including pumps and supporting pipes and valves, an electrical system, a standby generator and odor control system; and above‐ground electrical equipment, including a new transformer.

How long will construction last?

The project is expected to begin construction in the summer of 2012 and be complete by the end of 2015.

What impacts will there be to Fauntleroy Way Southwest and the Fauntleroy Ferry Terminal?

All lanes of Fauntleroy Way Southwest will remain open during construction. Some temporary delays may occur when construction vehicles and equipment are moving in and out of the construction site. Flaggers will help move construction vehicles in and out of the work site and the contractor will time movement of construction vehicles to avoid busy ferry travel times.

As construction wraps up, there will be sporadic daytime closures of the northern ferry lane entrance and toll booth.  Starting in September, neighbors and commuters can expect a two-week, 24 hour/day closure with daytime closures occurring the week prior to and after the two week full closure. These closures are needed to restore the sidewalk in front of the pump station and the retaining wall between the pump station and the ferry terminal.

Will this project require weekend and/or night work?

Work hours will typically be between 7 a.m. and 6 p.m. The project may require some night work in order to complete certain activities. Advance notice will be provided of all work outside of regularly scheduled hours.

How much noise should I expect?

Construction can be noisy. King County is committed to being a good neighbor and will work to minimize noise impacts to the extent possible. Individuals with concerns about noise should contact King County immediately using the project hotline. Prompt notification about noise concerns helps the team pinpoint the activities the community found disruptive.

Where can I access the beach during construction?

To keep the public safe, the public beach and Cove Park will be closed during construction. There is public beach access two‐tenths of a mile north of the site at the south end of Lincoln Park.

Where can I find more information about the project?

For more information about the construction schedule, site plans, and project updates visit the project home and library pages.

Who do I call if I experience problems or have questions during construction?

We have a 24‐hour project hotline to answer any questions or concerns and to assist with any problems that may arise during construction. Please call us at 206‐296‐2999.
