If you run, walk, rollerblade, skateboard, ride, etc., along Alki Beach during the day, you might have to change your plans next Tuesday, according to this alert just out of the WSB inbox:

On Tuesday, March 4, a King County crew will perform maintenance to the 53rd Avenue Pump Station, a below-ground facility near the corner of Alki Avenue Southwest and 53rd Avenue Southwest, on the west side of the street next to the sidewalk and waterside walking path.

Work will take place between 8 a.m. and 3 p.m., and will involve opening a hatch to replace the pump station’s carbon filter. The crew will need up to three vehicles for this work, and while the replacement work is under way, there could be some increase in noise and odors.

We have the city’s approval to close off the work area, including closing the sidewalk and walking path, but we’ll try to maintain access for walkers, joggers and bicyclist as much as possible. It’s possible that the work will require us to detour foot and bicycle traffic to the other side of the street.

This is the pump station that was expanded over a 2+-year period between 2008 and 2010.
