Zion carries a distinctive planned street grid along with industrial and residential development, and each completed project must be documented against its approved plan. A final as-built survey records the true placement and elevation of the finished work. Pi Surveying prepares the closeout documentation for the responsible parties.
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 city of Zion has about 24,655 residents across the Zion and Benton townships in Lake County. Waukegan serves as the county seat, and plats and easements for Zion property are recorded through the Recording Division of the Lake County Clerk’s Office. Because the northeastern county drains toward Lake Michigan and the Des Plaines River watershed, a final as-built survey confirms that grading and stormwater facilities were built as engineered. That confirmation supports the city’s acceptance of a completed Zion development.
It requires a measured record confirming pavement, grading, utilities, and stormwater facilities were built in their approved locations and elevations before accepting the improvement.
Yes. The surveyed constructed conditions feed record drawings showing what was actually built, which supports future work on the site.
An Illinois Professional Land Surveyor prepares and certifies it, giving the closeout document standing with the reviewing authority.
