Lyons is a small western suburb along the Des Plaines River, where riverfront land, older neighborhoods, and commercial corridors shape a compact, drainage-sensitive setting. Confirming that finished grades and structures match the approved design is a serious step before the village accepts a project. A final as-built survey records the completed improvements’ locations and elevations and compares them to the plans on file.
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.
Lyons has about 11,000 residents and spans Lyons and Riverside Townships in western Cook County. Its riverside position places it within the county’s flood-aware Des Plaines corridor. Plats and recorded survey records for the village are maintained by the Cook County Clerk’s Recordings Division. At acceptance, that as-built confirms the finished riverside work was graded to the elevations the approved plans required.

Because Lyons lies along the Des Plaines River, the as-built’s recorded elevations let the village confirm the site was graded to the approved plan before accepting the work.
It is a survey documenting the constructed location and elevation of completed improvements, compared against the approved plans, used at closeout.
It is needed once construction is complete, during the municipal acceptance process.
