Crystal Lake is the largest city in McHenry County, a suburban hub in the county’s southeast that grew around its namesake lake and rail connections. Its dense residential development and recreational-water setting make plats of survey a common reference for permits and closings. Boundary clarity supports the many additions and fences typical of an established suburb.
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.
Crystal Lake has a population of roughly 40,000 and sits within Algonquin Township, also spanning the Nunda and Grafton townships in southeastern McHenry County. Plats and deeds for the city are recorded with the McHenry County Recorder in Woodstock, the county seat to the northwest. McHenry County drains toward the Fox River and Chain O’Lakes to the east and the Kishwaukee to the west, and preliminary FEMA flood maps for the county were released in 2024, so parcels near lakes and streams should be checked against current mapping. In this densely developed community, plats of survey most often support fence and addition permits and confirm boundaries between neighboring lots.
