HomeServicesResidential Boundary Surveys › Mendota, IL

Mendota is a small city of roughly 7,060 in the northwestern corner of LaSalle County, surrounded by productive farmland. Its town lots and the agricultural parcels at its edges both benefit from a plat of survey when ownership, boundaries, or improvements are in question. Confirming corners against the record helps avoid disputes on lines that may not have been surveyed in years.

What a plat of survey shows

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.

Mendota & LaSalle County specifics

With about 7,060 residents, Mendota occupies Mendota Township in the far northwest of LaSalle County, well away from the county seat at Ottawa. The surrounding country is heavily agricultural, so surveys here often involve rural boundary retracement and farm parcel description as much as in-town residential lots. Plats are recorded with the LaSalle County Recorder of Deeds in Ottawa. A licensed Illinois surveyor researches the recorded description, recovers existing monuments, and identifies easements and encroachments, providing a drawing that ties the deed to the ground.

Yes. A surveyor re-establishes the recorded boundary from monuments and measurements, showing whether an existing fence sits on, over, or short of the true line.
