The communications between NYC and the Town of Putnam Valley indicate that the pump house is on Lake Peekskill property (correction: Town of Putnam Valley property). The check valve and the gate valve are in a pit that may be in NYC property, but that shouldn’t be such a big deal.
There was something that was done when the town disconnected the district water system back in 2004, but I haven’t seen any of that yet. I have to figure out what to ask for. The Laberge report on disconnecting and the town resolution were circulating in the fall when the original agreement was circulating.
