Developing Sinkhole in Dayton Ave N. at 122nd Street

[Pedersen, Alex]

Thank you for adding me to the thread to alert me to this. 

As the Chair of the Committee that monitors both SPU and SDOT, I’ll inquire with SPU and cc SDOT and the district Councilmember. Also, the location you note  (southbound lane of Dayton Ave. at N 122nd Street) appears to be in Council District 5 so I’m looping in the office of Councilmember Debora Juarez and moved CM Strauss to bcc so he knows I replied. 

Regards,

Alex Pedersen

City Councilmember

District 4, Seattle, WA

CAUTION: External Email

I question whether that's due to a broken culvert (which would imply it's one of the culverts that carries a watercourse under the road - there are none nearby). There are only 2 utilities shown on the city's SPU website at that location: 

A waterline runs under the east side of the road (you can see where from the maintenance hole at 122th - the line runs straight under Dayton  from there

A sewer line (combined sanitary and storm sewer) runs slightly west of the centerline of the road (you can see where from the maintenance hole at 122th and another at midblock- the line runs straight under Dayton from there.

And of course, each house along the road has both a house water line and a side sewer connecting to the mains.

My speculation is that it's a leak from any of the above (the water or sewer main or a house's water or sewer connection) that's carving out a void under the road.

The void will keep getting larger until the appropriate pipe is fixed regardless of what is done at the road surface. Those can require a fair amount of work when caught early (like now), but those sorts of voids keep growing until a sinkhole develops if not attended to.

I've added the chair and vice chair of Council's Transportation & Utilities Committee to this thread.

In so many words ‘yes we have’ and that was SPU who did the repair job, removed the cones and left it in a precarious condition. Today SPU generated a new work order - put sand bags in as a temp measure.  They’ve noted there is a broken culvert underneath the road. Let’s hope they will repair that ‘underlying problem’ before the serious rains hit.

LOL. And of course he punts it to D5 like we don’t know what district we’re in. I’m sure Juarez will be a big help. 

The last time I raised a road / RoW condition issue with her office, she said “I’m not SDOT!”. She’s just too busy getting ready for Hockey season and more photo ops with Durkan.
