People who grew up near Airmont remember the Rockland County plat book as the book that named every farm. Here's what a plat book is, where to look for one in Rockland County, and the free official map that stays current between editions.
How to use the Rockland County plat book
A plat book, sometimes called a land atlas, lists each township in Rockland County as a page, with ownership blocks labeled by owner name and approximate acreage. Deeds and recorded plats, not the atlas, still govern land near Hillcrest in the county.
Step one: the free Rockland County viewer
Rockland County publishes its parcels on the Rockland County parcel viewer, free to use for a lot in Ramapo or a property near Orangetown. Use the search box for an address in Ramapo or a parcel number, or simply zoom in and click a property near Orangetown. If the official address for the Rockland County, NY map ever changes, our directory page carries the current link for Ramapo and the rest of the county.
Current and older editions
Private publishers have printed plat books for many rural counties, but editions for Rockland County come and go; check at the courthouse, the extension office or a farm supply store in New City. Collectors and genealogists prize old Rockland County atlases since they show farm names and owners near Hillcrest long before online maps.
What a plat book page lists near Haverstraw
Plat book pages for Rockland County typically include an index of owners, so you can locate a family name near New City without knowing the township. Acreage printed in a county atlas is approximate; the deed and a fresh survey decide the real figure for a property near New City. Genealogists in New York often pair an old Rockland County atlas with deed records to follow a farm through the generations.
Editions, deeds and printouts
Farm families near Airmont often keep successive editions of the Rockland County plat book, which together show how ownership shifted over decades. Saving PDFs of the county map around Hillcrest gives you an offline reference when the signal drops.

Smaller places such as Bardonia, Blauvelt, and Congers appear on the Rockland County map as little clusters of lots. Rockland County had an estimated 340,807 people in 2023 (Census Bureau), spread across about 173 square miles. Subdivision lots dominate the county map around New City, and open tracts are scarce.
