Surveying in St. Charles, MO

St. Charles is one of the oldest towns west of the Mississippi, and its historic core shows it. Along South Main Street and in Frenchtown, narrow lots run back from the Missouri River in a pattern laid out long before modern platting, and many buildings stand right at the lot line or share walls with their neighbours. Owners restoring a brick storefront or a French-style cottage frequently need a survey that untangles old city block descriptions. We take the request, confirm the price and send a licensed surveyor from our team or network who has worked those early records.

Away from the river, the city is mostly post-war and newer subdivisions stretching west toward Interstate 70 and Highway 94. Here the typical jobs are more familiar: a fence along a rear lot line, a deck or room addition that has to respect platted setbacks, or a buyer's lender asking where the house sits within its easements. Because St. Charles is also the county seat, the Recorder of Deeds that holds every plat for these neighbourhoods is downtown, a short walk from the historic district itself.

The Missouri River defines the city's eastern edge, and low ground near the riverfront and the Katy Trail sits within mapped flood zones. Smaller streams such as Cole Creek and Boschert Creek cross residential areas on their way toward the river, and homes beside them can fall near a floodplain line. If your insurer or the city's permit staff raise flood risk, a licensed land surveyor in St. Charles can prepare an elevation certificate showing how your lowest floor compares with the mapped flood level.

St. Charles survey questions

Why are old St. Charles lot descriptions hard to follow?

Parts of the city were laid out in the French colonial and early American periods, and some deeds still refer to original city blocks and lot numbers rather than a modern subdivision plat. A licensed surveyor traces those references through the recorded chain of title before setting or confirming corners.

My Frenchtown building sits on the property line. Is that a problem?

Not by itself, since many older buildings in the historic districts were built to the line or with shared walls. A survey shows exactly where the walls fall relative to the deed, which matters for a sale, a refinance or any exterior work that touches the neighbour's side.

Does my home near the Missouri River need an elevation certificate?

If it sits in a FEMA-mapped special flood hazard area and carries a federally backed mortgage, your lender will normally require flood insurance, and an elevation certificate can help set the premium. Check the current flood map, and if you are close, we can schedule a licensed surveyor to prepare one.

Who reviews fence and addition permits in the city?

Inside city limits, the City of St. Charles handles building and zoning permits. Ask its permit staff what they want on the site drawing, then a licensed surveyor can show your lot lines, setbacks and easements in that format.
