The Open Planning Project just released a small community website for those in the greater NYC area: http://www.blockpartynyc.org

From here:

Block Party NYC is a new program by the New York City Streets Renaissance Campaign helping neighborhoods around NYC come together and enjoy their street, free from the usual hazards and distractions of automobiles. This summer, we’re providing mini-grants to over 30 block parties throughout the 5 boroughs, [as well as] the services of a professional urban planner to combat community problems like traffic, speeding, noise and air pollution.

Interested in meeting your neighbors? Getting outside? Having some good ol’ fashioned family fun? Well here’s your chance.
