5:09 PM: Thanks to Betsy for the photo and report: Beach Drive by Constellation Park south of Alki Point is blocked by a crew working on a water break. We don’t know yet how many customers are affected.

6:03 PM: Just went by to check (photo added). The Seattle Public Utilities crew tells us they haven’t yet reached the actual break, so this is going to take a while longer.

11:29 AM: Thanks for the tips! A power outage is reported to be affecting part of The Junction. So far the City Light map only shows 1 customer but that’s not always precise.

11:46 AM: SCL has updated to 419 homes/businesses affected.

11:58 AM: Actually two pockets – we’ve added a screengrab from the SCL map – totaling 450+ homes/businesses. No official word yet on the cause. Restoration time is estimated as 7 pm but remember, even SCL acknowledges those times are just speculative – could be sooner, could be later.

12:27 PM: And we’re getting word at least some of the power’s back on, after just about an hour.

12:41 PM: The SCL map has updated, showing the 419 customers (homes/businesses) in the larger pocket are back on, but the 32-customer pocket near 41st/Edmunds is still shown as without power.

3:56 PM: And the smaller pocket has since had its power restored too.

11:39 AM: Thanks to Ryan for the tip. California SW is wet just north of Admiral Way because of a water break. Seattle Public Utilities has a crew on scene investigating but they haven’t yet scoped out what repairs will be needed.

3:07 PM: Just came back to check. A repair crew is on scene and working in a big hole in the northbound lane.

Just after 11 am, a very brief power interruption hit us here in Upper Fauntleroy, and we also heard from Gatewood, Westwood, and High Point. Since that means some people might come home to flashing stove clocks (etc.) and wonder what happened, we checked with Seattle City Light‘s Scott Thomsen, who tells us the cause is listed as “squirrel.”

7:52 PM: Thanks for the tip – Seattle City Light says 133 homes have lost power in upper Alki/west Admiral. While the outage map says SCL is investigating the cause, we note the SFD real-time log shows a recent “wires down” call on Bonair (1900 block).

8:32 PM: Just checked the map again and this outage is apparently already over!

(South Operations Center rendering, from city website)

Almost three years after we first reported on Seattle Public Utilities‘ plan to take over the former bus yard at 4500 West Marginal Way SW, just south of the West Seattle Bridge, the project has won a key land-use approval. Today’s city-circulated Land Use Information Bulletin includes an announcement of the decision. We published details last year about what SPU plans for what it will call the Drainage and Wastewater South Operations Center, and also covered a briefing given to the Highland Park Action Committee. You can read the full decision here. Today’s notice of approval opens a two-week period if anyone wants to file an appeal – the notice explains how. At last year’s briefing, SPU said it expected to start construction on the “retrofit/remodel” project next year; we’ll be checking to see if that’s still the plan.

8:30 AM: Thanks for the texts. Ours is out too. We’re getting reports from a widespread area – as far north as Admiral. More to come.

8:38 AM: City Light map says more than 16,000 homes/businesses are out. Remember that intersections are four-way stops when the signals are out.

8:46 AM: City Light says via Twitter that they “believe the outage was caused by a switching problem and estimate power will be restored about 9:15 a.m.”

8:50 AM: It’s been six days since a similarly widespread outage (WSB coverage here) was blamed on a “relay malfunction,” though that one lasted only a few minutes.

8:53 AM: Our power’s back (Fauntleroy/Gatewood line). Yours? We of course will be following up with SCL. Also note that – as happened after last Tuesday’s even-shorter outage – there may be some lingering effects like flashing traffic signals.

9:26 AM: Just talked with Scott Thomsen at City Light, who is looking into questions such as whether this was human error, a mechanical problem, etc. He says the “routine maintenance” at the Delridge Substation continues so that’s one thing this did have in common with last Tuesday’s outage. We will update again later when we get more followup information.

2:23 PM: SCL’s Thomsen says via e-mail: “Crews were testing switchgear at the Delridge Substation as a part of our maintenance and reliability work. When one of the workers closed the doors for the switchgear they were testing, the vibrations tripped a relay, which then opened, cutting off power for the electrical bus (imagine a giant power strip connected to four feeder lines going out of the substation into the neighborhoods). Our engineering staff is looking at what we can do to dampen vibrations and avoid a repeat of this problem, which does occasionally affect utilities.”

2:32 PM: Thanks for the tips – it’s not fully showing on the City Light map yet but we have reports of a far-flung West Seattle power outage. We have reports from Alki to Westwood. More to come.

2:40 PM: Back on already for many including us in Upper Fauntleroy. Will update as soon as we find out from SCL what this was about.

2:50 PM: According to comments, some are still out, and SCL is unreachable. (We have a message out to their media reps.)

The map now shows 444 customers out but continues to show it as many individual outages, which is not the way an outage usually would display.

3:02 PM: SCL spokesperson Hernann Ambion tells us a “relay malfunction” related to “routine maintenance” caused the short-lived outage. He says everybody’s back on but the map still shows some outages because the system read the problem as the Delridge Substation being offline when it wasn’t. He says everyone should be back on now.

3:17 PM: Couple of side notes: Your cable/wi-fi router might need a reset – we’ve seen that happen in some power outages, even short ones. Also, if you heard sirens/alarms, this triggered a lot of fire alarms and stopped elevators; you can see the evidence on the SFD real-time log (all the calls with SW addresses).

5:40 PM Scattered traffic-signal trouble, still. Such as Fauntleroy Way at Fairmount Park, flashing and with SDOT on scene.

10:31 AM: A 78-customer power outage that stretches eastward across the Duwamish River is affecting south Harbor Island. Thanks for the call that tipped us to this – the screengrab above is from the Seattle City Light outage map. No word yet on the cause.

11:52 AM: Mary reports in comments that the power’s back on; the City Light map indeed shows the outage is over. We’re checking on the cause.

Thanks to Megan for the tip via Twitter: She says a “crash” was heard at Oregon 42 and then the power went out. The City Light map – itself suffering an outage when we first checked, but working again now – says 138 customers are out, pretty much right on that corner, southeast side of 42nd/Oregon. Cause is listed as “bird/animal” and SCL hopes to fix it within a few hours.

(Added 12:10 pm: Map of outages)

11:19 AM: Thanks for the tip: The Seattle City Light map shows 184 homes/businesses out in Highland Park/Puget Ridge, along 16th SW. No word on the cause yet; Brian says via e-mail, “Explosion was heard toward SSC and then power went out.”

12:03 PM: Checking the SCL site for an update, we see another 299 customers went out just west of the original outage zone, mostly along 21st SW, about half an hour ago. (updated) Added a map image for both outages.

1:19 PM: Tipster Aaron notes that SFD is/was checking out transformers near Riverview Playfield. Meantime, the newer, westernmost outage has dropped in size by about a third.

8:46 PM: As this has stretched on for so long, we tried SCL’s after-hours media pager and just got a call back. The outage was caused by a fire at the base of a pole in the greenbelt by SW Holly – the cause hasn’t been determined – but it’s been difficult for crews to access; they’re “close” to restoration, the spokesperson says.

10:17 PM: We noticed a few minutes ago that the outage was down to 191 customers. And we just got a text that power’s come back on at 21st/Holly. The map might not reflect that immediately.

10:40 PM: Looks like that was it – all but a handful are reconnected, after ~12 hours.

Thanks for the tips on this. A Seattle Public Utilities repair crew is on the way to fix the break that has sent water over the top of Admiral Way hill, just south of the viewpoint. The SPU employee on the scene now tells us only one house is without water and that repairs will have to be made on the other side of Admiral – so be careful tonight if you’re driving/riding through that area.

1:28 PM: Thanks for the tip – City Light says more than 80 homes lost power at midmorning on west Charlestown Hill. “Equipment failure” is listed as the cause, and the restoration estimate is 4:18 pm – could be sooner, could be later.

3:10 PM: A few homes have their power back – City Light’s map has downsized the outage to 69, though it’s also changed the cause to “investigating.”

5:48 PM: Outage over since last we checked, per SCL map.

For all the times we’ve written about what to do if your tap water is brown/discolored … this time it’s happened at WSB HQ. So in case anyone else in Upper Fauntleroy or vicinity is experiencing it, we did call Seattle Public Utilities – which wants to hear from you if it ever happens where you are – at 206-386-1800. They say hydrant use in the area has stirred up sediment. (Here’s SPU’s complete “what if my water’s discolored?” page.)

We hope everyone’s aware of this scam by now but just in case – we got a call from Luna Park Café a little while ago, and they had just received the infamous utility-scam call. Businesses are a favorite target of these scammers, who claim your power’s about to be cut off unless you pay some money right now. Utilities including City Light say they don’t do business that way. But if you get a call like that and somehow fear you might be in arrears, you can call the utility to be sure. All the info you need is here.
