This site gives you contact information for the person for each piece of vacant public land who we think has the ability to tell you it's status and give you permission to use it. Sometimes our sluething is off -- or sometimes people change jobs. When you call, start by asking if they are the person you should speak to about a vacant property in North/South Brooklyn. If they're not, ask who is (and remember to tell 596 Acres!).
If they are, tell them you are calling from a neighborhood organization. Describe the lot, how long it's been empty. Give the Block and Lot number and maybe the address.
