1. WSDOT has created a map, obtained by PubliCola, that shows how much the ground has sunk around the Bertha repair shaft—that's the red circle on the left side of the drawing.
The deep blue, purples, and pink areas represent the worst of it (1.1 inches to 1.39 inches) while the green areas have sunk much less, zero to 0.49 inches.
The deep blue epicenter (ground zero is at Cowgirls Inc.) and the magenta around it—areas that have sunk 1.1 inches to 1.39 inches—are concentrated south of the spot where the tunnel contractor is digging to rescue Bertha, pumping out water so they can hoist part of the boring machine up and try to fix it.
The only tunneling that has happened to date has been south of the repair zone—adjacent to where the ground has sunk the most dramatically.
I'm no geologist, but it looks like there's a relationship between the tunneling and the most susceptible or destabilized earth.
I'm no engineer either, but I'd say proceed with this project at your own risk Seattle.
2. Meanwhile, KIRO has the news that SDOT is reviewing emergency plans in case they have to close the viaduct, which itself has sunk more than an inch. SDOT would channel traffic to 1st, 2nd, 4th, and Denny and may remove parking on those streets to ease traffic.
SDOT Director Scott Kubly cancelled a long-scheduled neighborhood meeting in North Seattle last night due to "issues with the Viaduct," according to North District Council members.
3. A new study shows that contrary to anecdotal conventional wisdom, Seattle is not gentrifying. (The metric the report used to measure "gentrification" was if a census tract had gone from 30 percent of people living in to poverty in 1970 to 15 percent in the same tract today.
As opposed to seeing a decline in poor neighborhoods, Seattle actually went from six tracts with high poverty rates in 1970 to 12 tracts today.
Overall, about one percent of people lived in poverty in Seattle in 1970 and about three percent do today.
This presents a strange question to progressives who insist Seattle is increasingly becoming a city for the wealthy: Are these good numbers or bad numbers?
