This playground is adjacent to the school building housing MS 352 Ebbets Field Middle School and PS 375 Jackie Robinson School. Along with the McDonalds across the street there are two other fast food restaurants only a block away. Incidentally, that huge apartment complex used to be the beloved Ebbets Field, home of the Brooklyn Dodgers (aka "Boys of Summer" and "dem bums").
With a relatively small investment of time and money, this could become a Portable Outreach Neighborhood Garden (PONG) like the one recently installed at PS 102 Bay View School in Bay Ridge, Brooklyn. A PONG in this space would certainly do much to improve the streetscape and the neighborhood diet.
