HomeServicesResidential Boundary Surveys › La Salle, IL

La Salle is a city of about 9,580 on the Illinois River in the western part of LaSalle County, adjoining Peru and Oglesby. Its older platted blocks and industrial river frontage make boundary retracement a common need before construction, sales, or lot-line disputes. A plat of survey grounds the paper description in the actual monuments and improvements on site.

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.

La Salle & LaSalle County specifics

La Salle spans LaSalle, Utica, Peru, Waltham and Dimmick Townships and sits along the Illinois River corridor, roughly a dozen miles west of the county seat at Ottawa. As a river community, some of its parcels sit near FEMA-mapped flood hazard areas along the Illinois, which a plat of survey can show alongside the boundary lines. Plats are recorded with the LaSalle County Recorder of Deeds in Ottawa. A licensed Illinois surveyor retraces the recorded lot or tract, recovers or sets monuments, and notes easements and encroachments that could affect a title or a proposed improvement.

What La Salle-area clients say

Frequently asked questions

The plat confirms exactly where your boundaries and easements are, so a new garage does not encroach on a neighbor or over a utility easement. That avoids costly relocation later.

Plats and deeds for La Salle are recorded with the LaSalle County Recorder of Deeds in the county seat of Ottawa, not in La Salle itself.

It is the process of following the original survey and recorded description to re-establish where the true property corners lie on the ground, using found monuments and measurements.
