Licensed Illinois land surveyors · Sealed plats for closings, permits & boundary disputes
Pi Surveying PLLC provides professional land surveying across LaSalle County, Illinois, from the county seat in Ottawa to communities throughout the region. We prepare plats of survey, ALTA/NSPS land title surveys, topographic surveys, FEMA elevation certificates and land-development surveys for residential, commercial and government clients. Recorded plats and easements are filed with the LaSalle County Recorder of Deeds. Because Illinois River and its tributaries cross the county, some parcels fall within mapped FEMA floodplains — our team can handle boundary, topographic and elevation work together where needed.
