Also from the ‘in case you wondered’ file: Why the windows rattled, and might again

(ADDED FRIDAY NIGHT: Newly published Port of Seattle video that, toward the end, shows one of these tests)

12:54 PM: We’ve just confirmed with the Port of Seattle that what rattled windows from Admiral to Pigeon Point a little while ago was another one of those rapid-load pile tests related to the planned Terminal 5 modernization project. Port spokesperson Peter McGraw says the test scheduled for yesterday – second one this week – was postponed until today because of the wind. Judging by the messages/questions we received, this one was apparently the most widely felt one yet. Here’s the original alert from December.

P.S. The next major step in the T-5 project, after this testing ends later this month, is the release of the draft Environmental Impact Statement, expected in May.

ADDED 1:32 PM: McGraw just sent word that two more tests are scheduled, Monday (~3 pm) and Wednesday (~noon).

ADDED 8:06 PM: The Port has just published a video explaining how the tests work, and showing one – we’ve added the video above.

    Definitely heard/felt @ 35th & Alaska. Hadn’t noticed the earlier ones.

    That rattled the entire hill.

    Is this what we are to expect when/if  this is approved?

    Is the Port going to be setting up monitoring on Admiral hill? With all the rain soaked soil  what about stability issues?

    Good questions/concerns Neighbor!

    I noticed new cracks on one of my interior walls on the East side. Will they pay for damages?

    Not a good time. The steep slope behind our house is delicate right now.

    It was a big explosive shake. I live on city view right above the terminal. What a crappy thing they are doing down there. Go sign the petition

    Look for the announcement for the draft EIS in the late Spring. The public will have the opportunity to comment further about the impacts of T5

    It was pretty bad. Up on the top of Pigeon Point I didn’t notice the shaking, but the NOISE. Sounded like the most sudden, loud C-R-A-C-K of thunder I ever recall hearing. We were out on the back deck enjoying the tiny bit of sunlight we had this morning when ~WHAM! The dogs were totally freaked and ran back inside, stumbling up the stairs. This is really not fun.

    Rocked our s–t up around 41st and Hill.  Dogs were freaking out

Sorry, comment time is over.
