Not long after we took that photo last week, excavation concluded at the site of the Murray Combined Sewer Overflow Project‘s future million-gallon tank. After a reader mentioned seeing a big excavator on a truck heading eastbound, we checked the project’s status today with Doug Marsano from King County Wastewater Treatment. He confirmed the conclusion of the 60-foot-deep excavation, which started two months ago, and said the next big job will be a three-day concrete pour for the 17-foot base on which the tank will rest – no dates set yet, but they hope to get it done before Thanksgiving. It’ll mean:
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 SW to pump the concrete into the hole. Trucks will enter the site from Lincoln Park Way SW and exit using 48th Ave SW. Trucks waiting to pour will park on Fauntleroy Way SW and Lincoln Park Way SW. 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.
That’s from the official construction update, which you can see here. In case you missed it in our early excavation coverage, here’s how much dirt was removed and where it went.
