Blue Island is a historic south Cook County city of about 23,000 set on a ridge above the surrounding lowlands, with a name that reflects its distinctive geography. Sitting near the Calumet drainage, the community pairs older platted neighborhoods with genuine flood considerations. A plat of survey here helps owners understand both their boundaries and their relationship to the flood maps.
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.
Blue Island has a population of roughly 23,000 and spans Calumet, Worth, Bremen, and Thornton Townships in south Cook County, one of the broader township footprints in the region. Historically a rail and industrial hub built on a glacial ridge, the city has older, tightly platted residential blocks near lower ground that drains through the Calumet system under the Metropolitan Water Reclamation District, placing some parcels within FEMA Special Flood Hazard Areas. Recorded plats for Blue Island properties are filed with the Cook County Clerk’s Recordings Division following the 2020 consolidation of the Recorder of Deeds. Surveys here commonly address encroachments on aging lots along with flood determinations near the waterways.
