HomeServicesAs-Built Surveys › Clarendon Hills, IL

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.

Clarendon Hills & DuPage County specifics

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.

Yes, finished grades are documented along with storm structure elevations so the drainage design can be verified against what was built.
