How safe is the block wall located at Rt. 9 & 240th St. SE.?

Recently there’s been several mudslides over the concrete block wall located at Route 9 and 240th St. SE. There was sufficient mudflow to go down the slope (in three places), to fill-in a gully and then go over the railroad tracks.

People living in the Wellington Hills area often joke about the block wall, calling it “The Great Wall Of Woodinville” while also speculating on when will “The Great Wall” collapse due to its bowing sides and the amount of fill dirt behind it?

How safe is “The Great Wall of Woodinville?” I don’t know but I would like to hear professional assurance that it isn’t about to tumble down.

Snohomish County expects 90% of the traffic going to their proposed Wellington Hills Sports Complex to enter from Route 9 and 240th St. SE. (across from Costco).

We’ve been told traffic on 240th has increased ten-fold since Costco was built.  Pre-Costco, there were about 300 cars a day using 240th and after Costco was built, traffic increased to 3000 cars a day.

The increase in traffic for the sports complex hasn't been stated, but, this is a busy intersection, and I ask, “How safe is it to drive by or be stuck in traffic next to the “The Great Wall of Woodinville?”
