HomeServicesAs-Built Surveys › Union, IL

Union is a small village in southwestern McHenry County where construction and site-improvement projects still conclude with a formal closeout. When work is finished, the built improvements must be measured against the approved plans. A final as-built survey provides the measured record of the finished improvements.

Union & McHenry County specifics

Union, home to about 550 residents, lies in Coral Township within McHenry County, whose seat is Woodstock. The area drains toward the Kishwaukee River watershed, with FEMA Special Flood Hazard Areas that preliminary FIRMs updated, so as-built grades are considered where projects approach regulated drainage. Village or county engineers use the as-built survey to confirm that a subdivision or commercial build was constructed within its easements and to design grade before acceptance. Recorded plats and related documents are filed with the McHenry County Recorder. The completed survey lets the village or county close out the constructed improvements.
