Union is a small rural village in southwestern McHenry County surrounded by farmland and open country. Its agricultural setting means most parcels are larger tracts with boundaries that a survey helps define. A plat of survey gives owners a dependable record of their land where lot lines are rarely visible from the road.
A plat of survey is a drawing, signed and sealed by a licensed Illinois land surveyor, that locates the corners and boundary lines of your lot and depicts the buildings, driveways, fences and recorded easements on the property. It is the document lenders, title companies and municipal permit desks rely on.
The Pi Surveying process — clear, sealed, and ready for your closing or permit.
Union has roughly 550 residents and sits within Coral Township in southwestern McHenry County. Plats and deeds for the village are recorded with the McHenry County Recorder in Woodstock to the northeast. Being in the county’s southwest, the area drains toward the Kishwaukee watershed, so low-lying and creek-adjacent parcels should be checked against FEMA mapping, with preliminary county maps released in 2024. Given the surrounding farmland, plats of survey here mainly address acreage boundaries, easements and occasional permit or transfer work.
