Streator’s construction activity leans toward infrastructure maintenance, small commercial buildings, and utility upgrades across an older street grid. When one of those projects finishes, a final as-built survey captures the true field location and elevation of what was constructed, set beside the plans the work was approved under. Municipal staff and project engineers rely on that comparison to accept the job.
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.
Streator has a population of about 12,500 and lies mainly in Bruce Township, straddling the LaSalle–Livingston county line, with its LaSalle County portion tied to the county seat at Ottawa. The city drains toward the Illinois River watershed, and mapped flood hazard areas in the wider region make as-built elevation records useful at closeout. After construction, the survey confirms that pipes, structures, and grades match — or note where they deviate from — the approved design. Property records for the LaSalle County side are filed with the LaSalle County Recorder of Deeds in Ottawa. For a mid-size rural community, the value of the as-built is a clean, defensible record that a project was built as intended.
It is typically prepared at the end of construction, once improvements are in the ground, so the municipality or engineer of record can verify built conditions before granting acceptance.
It measures the as-constructed horizontal location and elevation of improvements — such as utility lines, manholes, curbs, and pavement — and presents them against the approved plan set.
The LaSalle County portion of Streator records deeds and plats through the LaSalle County Recorder of Deeds in Ottawa.
