Seneca sits along the Illinois River, where municipal, utility, and small commercial construction occasionally call for documentation once the work is done. A final as-built survey records the constructed location and elevation of those improvements and sets them against the approved plans. For a riverside village, that finished-condition record often anchors closeout and acceptance.
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.

Seneca is a village of about 2,353 people, seated primarily in Manlius Township and extending into Grundy County townships, within LaSalle County, whose seat is Ottawa. The Illinois River borders the community, and FEMA flood hazard areas along that corridor make built elevations a real factor at closeout. Following construction, the as-built survey ties finished elevations and structure locations to the approved plans so a reviewing engineer or agency can accept the work. LaSalle County deeds and plats are recorded with the LaSalle County Recorder of Deeds in Ottawa. In a river-edge village like Seneca, an accurate as-built confirms that work was built to design.
It provides the measured, as-constructed record of improvements — location and elevation — that an engineer or municipality reviews before accepting a completed project.
The LaSalle County portion records deeds and plats through the LaSalle County Recorder of Deeds in Ottawa.
