Chelsea:
Seriously (not always easy to do here), the draining was undoubtedly programmed. Virtually all the bodies of water in TV are connected in some way to the public-area irrigation system. That's why you may see them watering along the main roads even while it's pouring down rain.
There's a fairly large pond along Belvedere Blvd, just across from the Pimlico Rec Center that has frequently been drained - mostly because of some faulty plumbing underneath.
Forget sinkholes!
