Land Surveyor in Collinsville, Illinois
Surveying in Collinsville, IL
Collinsville sits right on the edge of the bluffs, which gives it two very different kinds of land. Uptown and the neighbourhoods around Main Street are on the higher ground, with older homes on compact lots and streets that climb and dip with the terrain. West of Bluff Road, the city drops into the flat American Bottom, where Cahokia Mounds lies inside the western city limits. Slopes, retaining walls and drainage paths shape many surveys up top, while flood mapping drives more of the work below.
The city also crosses a county line. Most of Collinsville is in Madison County, but two sections extend south into St. Clair County, so the first step on any job is confirming which county holds the parcel. That decides whether the deed is recorded in Edwardsville or in Belleville. We sort that out when you send the address, confirm your price, and schedule a licensed surveyor on our team or in our network who is familiar with both counties' records.
Schoolhouse Branch drains the northwest part of town and Canteen Creek drains the south, both running west toward the bottomland. Homes along those creeks, and properties near the base of the bluff, are the ones most likely to need an elevation certificate. Elsewhere, the usual reasons are a sale, a refinance or a new fence on a lot whose old line nobody has checked in years.

Collinsville survey questions
Is my Collinsville property in Madison County or St. Clair County?
Most of the city is in Madison County, but parts on the south side are in St. Clair County. Your property tax bill or either county's parcel search will show which one applies, and that decides where your deed is recorded.
Does building on the bluff change what a Collinsville survey shows?
A boundary or property survey shows lines and improvements either way. If you are planning a new building, addition or retaining wall on a steep lot, a topographic survey adds ground contours that an engineer or builder can design from.
Can you survey land near Cahokia Mounds?
Private parcels around the site can be surveyed like any other. The state historic site itself is public land, so any work involving its boundary would need to be coordinated with the site's managers.
