Riverdale is a south-suburban village of roughly 10,700 residents, spanning Thornton and Calumet townships near the Little Calumet River. Its low-lying setting makes a plat of survey especially useful for combining boundary work with flood-hazard review.
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.
Riverdale, with about 10,700 residents across Thornton and Calumet townships, sits in the south suburbs of Cook County near the Little Calumet River. Its plats of survey and deeds are recorded through the Cook County Clerk’s Recordings Division, which replaced the Recorder of Deeds in December 2020. The village’s older residential lots carry decades of fences, garages, and additions that can drift from the recorded plat, so a survey often clarifies lines and easements before permits or sales. Because the area lies within the Calumet river system, low-lying parcels should be reviewed against FEMA Special Flood Hazard Areas in the MWRD-managed watershed, which can be significant for building and insurance.

Parcels near the waterways can fall in FEMA flood-hazard areas, and a survey paired with that mapping clarifies flood exposure for building and insurance.
Typical triggers are a sale, a fence or addition permit, or a boundary question with a neighbor.
