New York City has a goal to have 85% of its residents living within a 10-minute walk from a park by 2030. Right now there's an average of 2.83 acres of green space (or a little more than two football fields) for every 1,000 residents, says New York City Parks Department assistant commissioner Alyssa Cobb Konon. But acreage varies depending on where you live. An interactive map displays the distribution of park space, with the dark pink areas representing places with less than two acres per 1,000 residents and the green spots representing areas with more than 12 acres. Lucky Crown Heights North has 23 acres of greenery per 1,000 residents, thanks to Prospect Park, while Williamsburg has just 2.5 acres. South Brooklyn and most of Queens are pretty starved for open space with some residents sharing just .4 acres. There's another map that shows the distance to the nearest park. Areas like Ditmas Park and some portions of the Upper East Side are furthest (meaning more than half a mile) from green space. [WNYC]
