Brooklyn schools are about to get swamped by a wave of overcrowding as the effects population growth and residential development hit dozens of neighborhoods. Meanwhile, the Education Department has done little to anticipate growth. The summary in today’s Daily News is grim. Take Williamsburg and Greenpoint: “…the City Planning Commission projects a general population increase of 12.5% from 2000 to 2010 because of thousands of new apartments being built. But Education Department consultants project an enrollment decline of 19.5%.” Meanwhile, in Downtown Brooklyn, “more than 3,000 housing units are under construction or were recently completed in the PS 287 school zone alone, yet no new capacity is planned for that area.” The problem is serious in many Brooklyn neighborhoods from Bath Beach to Bushwick where the city has apparently failed to plan for population growth that everyone knew was coming.
