Algonquin sits along the Fox River in the southeastern corner of McHenry County, a suburb that has grown through residential subdivisions while extending across the county line into Kane. Its river setting makes floodplain location a real survey consideration for many parcels. A plat of survey helps owners place improvements while respecting both boundaries and the river corridor.
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.
Algonquin has about 30,000 residents and lies within Algonquin Township, with the village also extending into Kane County. Plats for the McHenry-County portion are recorded with the McHenry County Recorder in Woodstock, while Kane-side parcels record with the Kane County Recorder in Geneva. Because the Fox River runs through the area, riverfront and low-lying parcels can intersect FEMA Special Flood Hazard Areas, and McHenry County released preliminary FEMA maps in 2024. With subdivision development dominating the housing stock, plats of survey here support closings, fence and addition permits, and boundary confirmation.
Yes. Algonquin is mostly in McHenry County but extends into Kane County, so a parcel’s plats may be recorded with either the McHenry County Recorder in Woodstock or the Kane County Recorder in Geneva.
The Fox River runs through Algonquin, so riverfront and low-lying parcels can fall within FEMA flood hazard areas that a plat of survey helps locate.
