The Rockland County parcel map turns a drive past an empty field near Clarkstown into a name, a parcel number and an acreage figure.
This guide walks through the official link, the kinds of land you'll find around Clarkstown, and what to do when the map and the ground don't agree.
Communities and countryside on the map
Most of the platted lots cluster in and around New City (the county seat) and Clarkstown, Haverstraw, Orangetown, and Ramapo. Don't overlook unincorporated places like Bardonia, Blauvelt, and Congers, where rural homesites often come up. The county's land area is about 173 square miles, and the Census Bureau estimated 340,807 residents there in 2023. Subdivision plats fill most of the map near Clarkstown; open acreage survives mainly at the edges of the county. Water features such as Pine Meadow Lake shape where lots fall and where floodplain sits. Public land in or near the county, including Nyack Beach State Park, Rockland Lake State Park, and Harriman State Park, changes how nearby private land sells.
Search by owner, address or parcel number
Go straight to the Rockland County parcel viewer, the county's own public parcel viewer. Try the search box with a Clarkstown street address first; for open land near Hillcrest, it's faster to pan and click. We track the link on our Rockland County directory page, so check there if it stops loading.
Property lines: what the map can and can't tell you
A Rockland County parcel map is built for assessment, not construction. In Rockland County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. In Rockland County, a rural deed may describe a line running to a creek, a stone or a neighbor's corner, which is why the map lines wander. If the map and the fence disagree, see why the deed and the GIS map disagree before you assume either one is right.
Where Rockland County deeds and plats are kept
The map near Clarkstown is only as good as the deeds behind it, and those are kept in the county's recording office. Check the county government website to see which office records deeds for land near Hillcrest. When the chain of title matters for land near Clarkstown, ask for the full deed history or hire a title company in New York.

Hunting land and landowner permission in Rockland County
Scouting around Stony Point? The parcel layer turns the woods into a list of named owners, which is exactly what you need to ask for access. Near Nyack Beach State Park and Rockland Lake State Park, the line between public and private matters. Pull up the parcel layer before you walk in. Check the New York State Department of Environmental Conservation for public hunting areas and current regulations before you hunt near Stony Point.

Vacant land and acreage on the Rockland County parcel map
To use the Rockland County parcel map for a vacant land search:
- Turn on the aerial imagery and scan for parcels with no house, barn or driveway.
- For the open ground around Stony Point, copy the owner, acreage and mailing address into a simple spreadsheet.
- Pull up three or four similar parcels near Stony Point and compare their land values.
- Confirm legal access. In Rockland County, as anywhere, a parcel with no road frontage depends on an easement.
- Before you buy, confirm zoning, flood zone and septic or well feasibility with the local offices.
If access is the concern, read how to tell if land is landlocked.
Two things the map won't tell you
A lot in Haverstraw that sold last month may still show the previous owner on the map. For a rural tract near Hillcrest, get acreage from a survey, not the tax record, if it matters for a deal.
