A person responded to this issue, and found no grease/oil. They found water leaking from a garbage can. 3/29/19.

Nope. I went back and checked. The residue on the sidewalk is grease. If you scrape up a bit and mix it in water you'll see the characteristic immiscibility. It's not terribly slippery today but it's likely to be more so with the upcoming precipitation. We need some sorbent here.

Thank you for this update. Our staff will look back into this issue and update you as soon as we can.
