Before 60-foot-deep excavation – pre-construction meeting November 6 for Murray overflow-control project

Demolition work is over at the future site of a million-gallon storage tank meant to reduce combined-sewer overflows across the street at the Murray Pump Station on Lowman Beach. As King County’s Doug Marsano told the Morgan Community Association last week, this is going to be a BIG dig – 80 feet wide and 60 feet deep. It’ll all be previewed at a public meeting planned for 6:30 pm Wednesday, November 6th. The official announcement has just arrived:

Construction of King County’s new water-pollution-control facility near Lowman Beach Park gets underway later this year.

Do you have all the information you want about the project activities, schedule, and potential impacts to the community? Please join King County’s Murray Combined Sewer Overflow (CSO) Control Facility project team for the project’s pre-construction public meeting!

The loss of housing is regrettable. But I think this project will enhance the neighborhood when completed.

I had no idea of the ginormous volume of that tank! I’ll be glad when it is completed and is doing its part to help stem the tide of 200+ million gallons of untreated sewage and storm water that routinely get discharged into the Sound every year in the City of Seattle.

80feet X 60 Feet X ??Feet?
There will be three dimensions to the hole.
Regardless, they are going to have to move a heck of a lot of dirt.
Once it comes out, where does it go?
I hope they will be able to have an estimated schedule; hours of operation and number of trucks per hour; and the route(s) they intend to use. Also, is there any pavement repair money in their budget to fix the damage they will inevitably inflict on our roads?
Is there going to be any impact on our already stressed bus system?
I can just see all the mud droppings all over wherever they go, for a very long time.
Did they consider pumping it out to a barge like the DB Tunnel?

Sorry, Old Timer, that’s all I got :) Got so caught up in imagining 80 feet long and 60 feet deep that I didn’t ask about the width. Well, and it was in the middle of a meeting, too. Probably in the docs somewhere but I’ll send off a question, easier than spending half an hour combing through … TR

I was an English major and it has been a while since I’ve looked at any Algebra or Geometry. But I think I saw somewhere that the tank will be 6,000 square feet. So assuming that refers to length and width wouldn’t that make it 80′ x 75′ ? If the depth is 60′ (and V=LxWxH) and the volume of a million gallon tank is 133,681 cubic feet then that doesn’t seem like it’s far off. Maybe someone smarter than me can check the math.
