On the site New Geography read Jan Rosenberg’s account of gentrification in Ditmas Park over the last 20 years. Here’s an excerpt:

Twenty some years ago my husband, 2 young sons and I moved from our
cramped 16-foot wide attached row house in Brooklyn’s trendy Park Slope
to a free-standing, 7-bedroom Victorian house in the Ditmas Park
section of Flatbush with stained glass windows, pocket doors, original
wood paneling, a back yard, front porch, driveway and 2-car garage in a
little-known, tree-lined neighborhood about 10 minutes away – on the
other, high-crime side of Prospect Park. Friends thought we’d taken
leave of our senses!

Built early last century, our neighborhood Long has been known for its
architecture, with the largest concentration of Victorian houses in
America. It’s the kind of neighborhood sensible new urbanists dream
about it; the only block in New York with subway stations at each end.
This was a tribute to the clout of the neighborhood’s original
developers who had a strong commitment to building “suburbs in the
city,” and secured the best in public transportation for their
customers.
