Tonica’s building activity is limited to municipal maintenance, utility work, and occasional small construction. A final as-built survey documents how those improvements were actually built — their field location and elevation — and lays that record against the approved plans. Engineers and village officials use it to confirm and accept completed work.

Tonica is a LaSalle County village of roughly 749 people in Eden Township, with Ottawa serving as the county seat. It lies within the Illinois River watershed that drains the county. After construction, the as-built survey records the constructed elevations and structure locations against the design so a reviewer can sign off on the project. County deeds and plats are recorded through the LaSalle County Recorder of Deeds in Ottawa. For a small community like Tonica, the as-built gives officials a clear record that a build matched its approved plans.
