Look Out Below on Troutman Street

Our Greenpoint correspondent sent us this photo, which was the result of some meanderings around East Williamsburg and Bushwick. She didn't get the exact address, but if you look at the photo you can understand anyone's reluctance to approach the building permit on the construction fence. She writes:

Look at the angle of that "chute" and note were the permits are placed. I know enough about physics to know this is a bad situation. Hence, why I didn't get the address; my sense of self-preservation prevailed.

Uh, is that chute, so-called, legal?
