Digging a trench with a dragline caught my eye. Cable driven backhoes probably existed in 1928, but they were not big enough to move that much dirt.
I checked, the O'Brien WRP was completed in 1928 so I presume tht this was the outfall for that plant. I had assumed that the outfall for that plant was into the North Shore Channel.

I wonder if this was the same dragline. We can see that it was a walking dragline.

When I Googled "park ridge outfall project," I discovered that Park Ridge plans to spend millions of dollars to build storm sewers and underground retention vaults to reduce flooding. [Dec 2017 plan]
