During the Open House New York weekend, I volunteered for the “From Pollution to Progress “walking tour of Gowanus in Brooklyn, where rezoning is underway. The Gowanus Canal is one of the most polluted bodies of water in the U.S. The rezoning includes not only high-rise condos, but also affordable housing for the area's low-income residents. This public children's pool is located near the canal. According to NYC Parks, this Douglass & DeGraw Pool is one of the public pools built in the early 1970s, generally referred to as "vest-pocket pools" (an allusion to the "vest-pocket park" trend in the late ´60s and early ´70s that helped transform small lots into "oases of green" for underserved city children). It is rather modest, but in the harsh midday Indian summer sun, with the shadow of the fence, it looked very beautiful and powerful.
