Land due diligence in Yorktown, NY.
Yorktown is where Westchester still has real acreage, and also where the most buildable-looking parcels fail — wetlands, watershed rules and septic feasibility take out more Yorktown lots than zoning ever does.
Most Yorktown land outside the hamlet centers depends on a private well and an on-site septic system. That makes soil the deciding factor. A parcel with the right acreage and the right zoning is still worthless for a house if the soils will not support a system and there is no reserve area. Mapped soil data and slope tell us early whether that is a live risk, and our report says plainly when a perc and deep-hole test should be a contract condition rather than an afterthought.
Large parts of the town drain to Croton reservoirs inside the New York City watershed, which layers additional stormwater and subsurface-sewage review over the town's own process. Combine that with state and federal wetlands mapping and the practical buildable area of a wooded ten-acre parcel can be a fraction of what the acreage suggests.
Access is the third recurring problem. Older Yorktown parcels are frequently reached over private roads or long shared driveways created by deed rather than by a filed subdivision map. Whether that access is recorded, who maintains it, and whether it satisfies the town's frontage requirement are three separate questions, and a buyer needs all three answered.
If you want the underlying method rather than the local version, start with our complete land due diligence guide or the free 47-point checklist.
Westchester County Clerk — Land Records Division
Deeds, mortgages, liens, easements and maps for every municipality in the county are recorded centrally in White Plains, with an online index. We pull the recorded instruments themselves, not just the index entry, and read each easement and restriction in full.
Town or village assessor and receiver of taxes
Assessment, deeded acreage, land class and tax status sit with the municipality, not the county. We reconcile the assessor's acreage against the county GIS parcel and flag mismatches, which are common on older subdivided lots.
Town of Yorktown zoning, wetlands and steep slope provisions
Zoning district and minimum lot area, plus the town's own wetland and slope controls, which can be stricter than state mapping alone.
Soils, wetlands and watershed mapping
NRCS soil survey ratings for septic suitability, national and state wetlands inventories, FEMA flood mapping and NYC watershed boundaries, assembled into one picture of usable area.
We work from these records remotely — no site visits, no survey, no brokerage. Our completed reports so far are concentrated in Texas and Pennsylvania; the records workflow is the same one we apply to a Yorktown parcel, and every source is cited so you can check it yourself. See a sample report for the exact format.
Yorktown questions we get
Can you tell me if a Yorktown parcel will perc?
No one can tell you that from records alone. What we do is read mapped soils, slope and wetlands to say whether a perc test is likely to be the deciding risk, and we recommend making it a contract contingency when it is.
How much land is actually usable on a wooded lot?
We estimate it by subtracting mapped wetlands and buffers, steep slope, flood area, easements and required setbacks from the parcel — and we show our sources so you can check the math.
Is a shared driveway a problem?
Only when it is undocumented. We look for a recorded easement, its width, who benefits and whether any maintenance obligation was ever put in writing. Missing maintenance terms are the usual finding.
