Westchester is a stable residential village west of Chicago where additions and select redevelopment make up most construction. Expanding a home on an established lot requires knowing exactly how the land sits. A topographic survey records the contours, improvements and drainage the design must work with.
A topographic survey maps the elevations, contours and natural and man-made features of a site — grades, structures, utilities, trees and drainage — giving architects and engineers the data they need to design accurately and secure permits.
The Pi Surveying process — clear, sealed, and ready for your project.
About 16,900 residents live in Westchester, which lies within Proviso Township in western Cook County. Recorded plats and easement documents for the village are maintained by the Cook County Clerk’s Recordings Division. The community sits within the Des Plaines River drainage, including the Salt Creek corridor, so grading and stormwater control frequently shape design. Topographic surveys provide the elevation base engineers use to manage runoff on additions and redevelopment parcels throughout the village.
