We regret that Block Party Applications and New Tree requests cannot be accommodated online. Please contact the office to apply for these two services. Regarding block parties, it is important to note that all necessary information and a money order must be in our office 65 days prior to the party (because the Mayor's Office must have it 60 days before the party). Be sure to include a money order (only) for $15.00 made out to NYC Dept. of Finance and a petition, which is drawn up by the person applying, stating that they would like the street closed on the date requested any time between 8 am to 11 pm. The petition must have 51% of the residents on the block signing, and they must each include their name, address, and phone number.
