Ottawa is the LaSalle County seat, a city of roughly 18,800 residents that grew up where the Fox River meets the Illinois River. Its downtown lots, older residential blocks, and riverfront parcels each carry their own boundary history, which is exactly why a plat of survey is worth having before a purchase, addition, or fence line goes in. Confirming corners against the record protects both a longtime owner and a new buyer.
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.
As the county’s largest community and its administrative center, Ottawa spreads across several townships including South Ottawa, Dayton, Rutland and Wallace, and it sits at the confluence of the Illinois and Fox Rivers. That river setting means many parcels near the water fall within FEMA Special Flood Hazard Areas mapped along the Illinois and Fox corridors, so a plat of survey here often needs to note flood zone lines alongside boundary corners. Because Ottawa is itself the seat, plats and related documents are recorded with the LaSalle County Recorder of Deeds right in town. A licensed Illinois surveyor typically retraces the original subdivision or metes-and-bounds description, sets or verifies monuments, and shows easements, encroachments and any waterway influence on the drawing.
Many lenders and title companies request a current plat of survey before closing so the buyer knows the exact boundaries and can see any encroachments or easements. It is not always legally mandatory, but in Ottawa it is a common and prudent step.
Ottawa sits where the Fox River joins the Illinois River, and parcels near either can fall inside FEMA flood hazard areas. A surveyor can note those mapped flood lines on the plat, which is useful for permitting and insurance.
Ottawa is the LaSalle County seat, so plats and deeds are recorded with the LaSalle County Recorder of Deeds, located in the city.
