I don’t know about you, but when I see the term “Private Street,” I think of Riverdale, the Bronx. I always thought that Riverdale has the most private streets, but actually the crown goes to Staten Island. Staten Island has 600 private streets. Imagine my surprise when I saw Parkside Place, a short dead-end street on the north side of Parkside Avenue, between Flatbush and Ocean Avenues. I didn’t expect it in such a densely populated area. It’s a few steps from the Parkside Avenue (BMT) subway station.
