HomeServicesAs-Built Surveys › Lockport, IL

Lockport blends historic canal-era character with newer residential and commercial construction throughout its township. As those newer projects finish, the constructed improvements must be surveyed and measured against the plans that approved them. That documentation of constructed conditions comes from the final as-built survey.

Lockport & Will County specifics

Lockport, with about 26,000 residents, sits in Lockport Township within Will County, and the county seat is Joliet. The city lies along the historic canal corridor near the Des Plaines River, where FEMA Special Flood Hazard Areas make accurate as-built elevations especially relevant for grading and drainage. When a subdivision or commercial site is finished, engineers and city reviewers use the as-built survey to verify that improvements were built in place and to the designed elevations before acceptance. Plats and related recorded documents are filed with the Will County Recorder of Deeds. That verified data closes out the project on a factual footing.
