HomeServicesPlat of Subdivision › La Salle, IL

La Salle is a river-and-canal city that grew up alongside Peru and Oglesby, its name tied to the county itself. Parcel divisions here run from infill on established streets to larger tracts on the community’s outer edges. A plat of subdivision is the recordable instrument that makes those lots official.

La Salle & LaSalle County specifics

With around 9,582 residents, La Salle spans parts of Utica, Peru, Waltham and Dimmick townships. As the community lies within LaSalle County, an approved plat is recorded with the LaSalle County Recorder of Deeds in Ottawa, the county seat. Creating lots, blocks, streets or easements requires review under the city’s subdivision and zoning ordinance, and drainage toward the Illinois River corridor can shape how a layout is drawn. Pi Surveying prepares both the boundary survey and the plat so the recorded parcels match the approved plan.

What La Salle-area clients say

Frequently asked questions

It is recorded with the LaSalle County Recorder of Deeds in Ottawa, since La Salle sits in LaSalle County and Ottawa is the county seat.

An easement is a defined area where another party — often a utility or the municipality — has the right to install or maintain infrastructure. The plat shows its location and width so it runs with the lots.

Any division that creates new lots, streets or easements is generally handled through a plat that meets municipal subdivision and zoning rules before recording, even a two-lot split.
