Surveying in O'Fallon, IL

O'Fallon started in 1854 as a stop on the railroad, and the blocks around the old downtown still follow the grid laid out near the depot. Most of the city's growth came much later, after Interstate 64 was widened in the 1990s and subdivisions spread out across the farm fields on either side. Neighbourhoods such as Thornbury Hill, Fairwood Hills and Nolin Creek Estates were platted with recorded setbacks, drainage easements and covenant rules that matter whenever an owner adds a fence, deck or pool.

Scott Air Force Base lies a few miles east, and military families buying and selling on reassignment timelines make up a steady share of O'Fallon's home sales. Those closings often depend on a lender or title company getting a survey quickly. Survey Coordinator takes the request, confirms the price and scheduling, and sends a licensed Illinois surveyor on our team or in our network. You get the sealed drawing from us along with one invoice, so there is a single contact even if you are moving from out of state.

Several creeks cross the city, including Ogles Creek, which has had its FEMA flood mapping revised near newer development, and Engle Creek, where the city has invested in detention and drainage work. Some O'Fallon streets have also seen repeat drainage problems after heavy rain. If your home backs onto a creek or a detention area, an elevation certificate or a survey showing the drainage easement can answer questions from an insurer, an HOA or the city.
