A special thanks to Bob Marvin for supplying these images. These images aren't exactly to scale, but if you squint and relax your eyes the right way you'll see a sailboat.
On the left we have the actual PLG Historic District. On the right is the proposed historic district from the 1970s. Note that the proposed district is larger and strangely fragmented. The actual historic district does not include some blocks further from Flatbush Ave. and some blocks of Lefferts Ave. and Sterling St.
On the idea of expanding the historic district, we're on the fence. On the one hand, preservation is important. However, some attractive new development wouldn't be a bad thing, either. Some of the newer condos built in Brooklyn are downright attractive and look great against the brownstone backdrop. Yes, some are ugly, but there's no point in being overcautious and preemptively resistant to change.
