King County just about ready to pour the 17 foot thick base for the Murray Basin CSO: Expect traffic disruptions near Lowman Beach
The tank area at the Murray CSO Control Project has been dug out and now the base concrete pour will take place. That base will be 17 feet thick, and constructing it will cause some traffic disruptions in the area as it is built.

information from King County
King County contractors finished digging out the tank area at the Murray CSO Control Project site on Thursday, November 13. The resulting hole is 60 feet deep – big enough to house the facility’s one million gallon underground storage tank. The tank will help keep sewage and stormwater out of Puget Sound.
Before the tank can be built, crews must install a 17-foot thick concrete base below the tank. The base will keep the tank from being pushed out of the ground by groundwater. Rebar will be installed in the next 10 days. Then nearly 5,000 cubic yards of concrete will be poured into the hole over three days to build the base.
About 20 trucks an hour will deliver concrete to the site to pour the base. Two concrete pump trucks will be located on the east side of Beach Drive S.W. to pump the concrete into the hole. Trucks will enter the site from Lincoln Park Way S.W. and exit using 48th Ave S.W. Trucks waiting to pour will park on Fauntleroy Way S.W. and Lincoln Park Way S.W. Flaggers will direct traffic around the site. To maintain local vehicle access, no parking will be available from 7 a.m. to 5 p.m. on the 7000 block of Beach Dr. S.W. and on Lincoln Park Way from Murray Ave. to Beach Dr. on pour days.
The contractor plans to complete the pour before Thanksgiving. No work is scheduled over the Thanksgiving holiday. Updated information will be provided when the dates for the pour are confirmed.
What to expect during the base pour:
• Concrete pours between 7 a.m. and 5 p.m. for three days
• Crews working on the east side of Beach Drive S.W. near Lowman Beach Park
• Trucks parked on Fauntleroy Way S.W. near 47th Ave. S.W. and on Lincoln Park Way S.W. near the intersections of 47th Ave S.W. and Murray Ave. S.W.
• No parking on the 7000 block of Beach Dr. S.W. between 7 a.m. and 5 p.m.
• No parking on Lincoln Park Way S.W. between Murray Ave S.W. and Beach Dr. S.W. from 7 a.m. and 5 p.m.
• Increased truck traffic entering and leaving the site during work hours
• Traffic delays and congestion
• East sidewalk of Beach Dr. S.W. closed between 7 a.m. and 5 p.m.
