(ADDED: Video of this morning’s entire meeting, above)
9:41 AM: Ten days after concerns about “settling” related to the Alaskan Way Viaduct Replacement Project, WSDOT reps are briefing the Seattle City Council right now. Transportation secretary Lynn Peterson says there appears to be “no further settlement” since what was reported a week and a half ago, and no damage to buildings in the area. She says that while this is a “tense moment” in the project, WSDOT firmly believes it’s “less risky” to proceed than to rely on the earthquake-vulnerable Viaduct. She also vows that the contractor, Seattle Tunnel Partners, is being and will be held accountable for what they’re expected to do. And she says they can’t commit to any kind of timeline right now for completion, because the cutter head has to be retrieved for repair first: “This is a design-build contract and we have purchased a tunnel … the fix .. is the responsibility of the contractor. We do not own the machine nor the method” STP chooses to fix it.
WSDOT’s Todd Trepanier tells the council STP was asked to stop excavating, at least temporarily, on Friday, until getting a green light for resumption. He’s getting into more technical points; here’s the slide deck just added to the agenda.
You can watch the briefing live here. After WSDOT reps are done explaining, and answering council questions about, the “settling” situation, city reps are scheduled to talk about the status of plans in place in case a Viaduct closure was needed. We’ll have toplines of that later; you can preview the slide deck (which involves a 2005 plan centered on “what ifs” in case of an earthquake) here, plus a new city update on the “settling” situation here.
11:26 AM: The meeting, originally scheduled for about an hour, has now lasted for two and isn’t likely to end any time soon – again, it’s live at seattlechannel.org. Councilmembers continue to press for more specifics on Viaduct safety – a moment ago, Councilmember Kshama Sawant was asking what size of earthquake would take the AWV down; WSDOT says it doesn’t want to speculate but notes they all believe the structure “is vulnerable.”
11:30 AM: City reps are now coming to the table to discuss the status of plans in case it was determined the Viaduct had to be closed – not just transportation, but utilities.
SDOT director Scott Kubly says the “unified command structure” has been meeting at least once a day to talk about the situation. Seattle Public Utilities says it’s been monitoring utility lines and pipes in the area – they’re using a hydrophone to “acoustically” detect water leaks, as well as using closed-circuit video to watch the sewer lines. The presentation embedded above this paragraph shows all the utility info they’re presenting, including what types of lines are in the Viaduct/tunnel-pit area, as well as the transportation plan that SDOT will discuss shortly.
11:46 AM: Now it’s SDOT director Kubly’s turn, after a council question asking SPU who covers the cost if there are utility problems – answer: the state. Meantime, he says that they are in “good shape” if a Viaduct closure was necessary, because the 2005 plan is updated each year. The “variable message boards” on paths to The Viaduct would be called into action, as would equipment like barricades etc. which he says are “pre-loaded” onto vehicles and ready to go at a moment’s notice, if needed. He is followed by Seattle City Light with its plans. Meantime, the Department of Planning and Development hasn’t heard yet of any buildings that would be deemed unsafe, but if settlement was “a lot steeper in areas,” they have authority to “do various things depending on how much damage we see … (including) ordering vacation of (a) building.”
11:58 AM: Councilmember Tom Rasmussen asks how Metro works into this plan if the Viaduct had to close. Kubly says Metro is “at the table” and they are looking at “how would we speed buses” and “what detour routes would be in place … how (to) add service would depend on length of the closure.” Could the plan deal with all 60,000 people/vehicles that would not be able to use the AWV? Kubly says it would address elements such as possible restrictions on “non-essential construction,” changes in deliveries, and looking at ways to get more people carpooling, using transit, etc. (The funding for extra transit is “already gone,” the council is told.) WSDOT’s Trepanier is asked to come back to the table to answer some questions, such as what if there’s a long-term gap between the Viaduct going out of service and the tunnel coming into service. He says the Legislature made the decision not to use any more project money toward “transportation mitigation” (such as transit).
12:13 PM: The Viaduct discussion is over and the council has moved into a preview of its 2 pm meeting, which will include the White Center annexation proposal. When the video of this meeting is available, we’ll add it to this story.
3:18 PM: Just added the video.
8:18 PM: Mike Lindblom of The Seattle Times (WSB partner) reports on the downtown water main that needs replacement.
