Part of the north end of Cal Anderson Park will be closed for more than a month starting Monday while city employees work on the underground Lincoln Reservoir, according to Seattle Public Utilities. We’ll try to find out exactly how much of the park will be shut down while crews run what is being called a regular inspection and cleaning of the 109-year-old reservoir.

Still hunting down a map that shows the exact dimensions of Lincoln but Google Maps graphics indicate a very large pool and this image from Wikipedia’s entry on Cal Anderson also gives a glimpse of the size of the reservoir.

In July, CHS reported that reservoirs in West Seattle and Beacon Hill were leaking and the same manufacturer and contractor had been involved in the construction of Lincoln. At the time, Seattle Public Utilities told CHS that there were no plans to remove the surface layer of Cal Anderson to inspect Lincoln.

The work could also coincide with the start of construction activity on the nearby Capitol Hill light Rail station site.

The Lincoln Reservoir is a major distribution point for the Cedar River pipeline which provides most of the potable water for central Seattle.

More when we get a chance to make a few phone calls on Thursday.

Project:  Seattle Public Utilities (SPU) construction crews will inspect, clean and make repairs at the Lincoln Reservoir as a part of regular maintenance.

Location:  Crews will work in and around the reservoir, located at 1700 Nagle Place, Seattle, WA, underneath Cal Anderson Park.

Description of Work:  The reservoir will be drained, inspected and washed.   Inspections of the reservoir’s roof, hatches, vents and screens will take place.  Repairs to the system will be made.  Debris will be removed from the reservoir’s perimeter and grounds as needed.

Dates/Times: Work is scheduled to begin on Monday, November 2, and last until Friday, December 11.  Crews will work Tuesday through Friday, from 7 a.m. to 5 p.m.

 Potential impacts during construction:

• A portion of the park over the reservoir will be closed to the public.

• Noise from power equipment and trucks.

• An increase in truck traffic in the neighborhood.

SPU tries to limit inconveniences to citizens, and safety is our top priority when working in neighborhoods and public facilities.
