Sound Transit can’t avoid the voids

The Seattle Post Globe fills us in on the filling of an eighth “void” along the tunnel excavation route at 18th and Lander. Another potential void is also being examined at 17th as well. Crews are expected to complete investigation and repairs by May 22nd.

After the initial report of the sinkhole that rose all the way to the surface, subsequent voids were identified by reviewing records of excavation spoils for abnormally high readings originally attributed to mismeasurement, accuracy, or instrument calibration issues.

BHB reader Heidi wrote this morning about having seen crews working at these repair sites (and being a bit hesitant about answering questions) and pointed out the crumbling retaining wall nearby. Interestingly, in the Post Globe report Sound Transit spokesman Bruce Gray states no structural damage has been reported from these voids and that only a quarter-inch of settling has been measured, and none of that near the void sites.

Thanks Heidi!

Parties, crime, and alcohol touched on at NBHC meeting

The North Beacon Hill Council met tonight at 7 at the Beacon Hill library. Very briefly, here’s what went down:

  • Reps from DPD present talked about outreach and prep for the next planning meeting May 30th.
  • An ad hoc committee and an outreach subcommittee of the Neighborhood Planning Advisory Committee is seeking a six month delay in the DPD neighborhood planning process to get outreach to more of the community and focus more closely on neighborhood issues specifically instead of Southeast Seattle issues generally.
  • Beacon Mountain Playground is moving forward with phase 1 of the project.
  • An SDOT representative will be at the June meeting to provide an update.
  • Some background on the Sound Transit tunnel voids was given by Roger Pence. There are believed to be only two unfilled voids remaining and they are being actively worked on.
  • Some discussion of the pedestrian safety, zoning, and environmental issues around the new car wash occurred, leading into a proposal to form a committee to work on attracting additional businesses to the hill and a motion to write a letter to the DPD concerning the zoning conflict with the transit overlay area.
  • Police updates included notice that staffing hours will likely change soon, focusing more bodies during the times of day when they’re needed. Also brief discussion of car prowls, burglaries, graffiti, car accidents, prostitution, etc.
  • Asian Express’s liquor license renewal is mentioned to be coming up soon, and it may be an opportune time to work out a “good neighbor” agreement to reduce the sales of high-alcohol beverages.
  • Volunteers were sought to staff the NBHC booth at the Jefferson Park festival on June 6th.
  • Michael Richmond mentioned the possible upcoming city council and mayoral candidate forums this fall. Previous candidate forums are said to have been especially well attended here on the hill.
  • The Piñata Party will be on July 18th this year — the same day as the Sound Transit Link Light Rail grand opening. This may be both good and bad.
  • Newly elected board members:
    • Matthew Stubbs
    • Sara Hasan

Underground voids found, filled by Sound Transit

In addition to the one that came all the way to the surface, the Seattle Post Globe reports Sound Transit has found an additional six underground voids above the bored tunnel on the East side of the hill. Six of the seven total found voids have now been filled with concrete at a cost so far of about $1 million. Keep an eye out for more shifting soil!

Update: KOMO reporter (and Beacon Hill resident) Travis Mayfield has a video report on this story.

Sinkhole develops over light rail tunnel

The P-I reports on a sinkhole that appeared at 18th and Lander above the northbound light rail tunnel. Numerous trucks delivered fill material today to solidify the 18-inch hole that widened as it descended. Sound Transit is monitoring the area for any further problems.

(Edited: An earlier version of this post said that the sinkhole developed “due to Sound Transit construction.” The cause of the sinkhole has not been determined.)
