Clarendon Hills sees ongoing residential rebuilding and drainage-conscious construction, and each completed project must be squared against its permit. A final as-built survey records the constructed elevations and locations for that comparison. Pi Surveying prepares it so the project can reach municipal acceptance.
A final as-built survey documents the actual location and elevation of completed improvements and compares them to the approved plans. Municipalities, engineers and owners rely on it to close out projects and confirm compliance.
The Pi Surveying process — clear, sealed, and ready for your project.
The village of Clarendon Hills has roughly 8,702 residents and lies within the Downers Grove township of DuPage County. Wheaton serves as the county seat, and plats and easements for Clarendon Hills property are recorded with the DuPage County Recorder of Deeds. Since local drainage feeds the DuPage River system, a final as-built survey confirms that finished grades and stormwater facilities were built as engineered. Clarendon Hills treats that documented match as the precondition for accepting the finished work.

Rebuilding changes grading and drainage, so the village often needs a measured record confirming the new construction was built as approved. The as-built provides that record.
Yes, finished grades are documented along with storm structure elevations so the drainage design can be verified against what was built.
An Illinois Professional Land Surveyor license is required to prepare and certify a valid as-built for closeout.
