Land Surveyor in St. Charles County, Missouri
Surveying across St. Charles County
St. Charles County is a peninsula. The Missouri River wraps its southern and eastern sides, the Mississippi runs along the north and east, and the two meet at the county's tip near West Alton. That geography explains much of the survey work here: broad river bottoms that flood, bluffs and rolling farm ground inland, and a fast-growing corridor of suburbs along Interstates 70 and 64. Survey Coordinator takes a single request, confirms the price and assigns a licensed land surveyor from our team or network who already works these records.
Land records for every town and every rural road in the county are filed with the Recorder of Deeds in the county government complex on North Second Street in St. Charles. Outside city limits, the county's own Unified Development Ordinance governs zoning, subdivision and building, so a family dividing acreage near New Melle or Augusta deals with county planning staff rather than a city hall. The county also publishes a public GIS map, which is useful for spotting parcel numbers and zoning but does not replace a boundary survey on the ground.
Flooding has shaped county policy for decades. After the great flood of 1993, many low-lying properties in places like Portage des Sioux and West Alton were bought out, and the county still manages that land as open floodplain. The county has followed a written floodplain management strategy since 1999 and requires a floodplain development permit before building in mapped areas. If you own land in the bottoms and need a land surveyor in St. Charles County, MO, an elevation certificate is often the first document a lender or permit reviewer asks to see.
What to know about St. Charles County
Unified Development Ordinance
Unincorporated land follows the county's Unified Development Ordinance for zoning, subdivision and building. Splitting acreage or adding a structure outside city limits starts with county Community Development, not a municipality.
Floodplain permits and buyout land
Building in a mapped floodplain needs a county floodplain development permit. Parcels bought out after major floods stay in public ownership, which can affect access and boundaries for neighbours along the river bottoms.
Two river borders
Few counties have as much river frontage. Missouri and Mississippi river bottoms, levee districts and shifting banks make careful research of older deeds and plats part of many surveys here.

St. Charles County survey questions
My property is outside any city in St. Charles County. Who handles zoning and building permits?
County Community Development does. Unincorporated parcels fall under the county's Unified Development Ordinance, which covers zoning, subdivision of land and building permits. Ask the county what it needs for your project first, and then have a licensed surveyor prepare the drawing in that form.
Where are deeds and plats for St. Charles County recorded?
At the St. Charles County Recorder of Deeds, located in the county administration building on North Second Street in St. Charles. It records deeds, deeds of trust, plats and other land documents for the whole county, including every incorporated city.
Can I use the county GIS map to settle where my fence should go?
No. The county's GIS mapping is compiled for reference and tax purposes, and parcel lines on screen can be shifted from their true position. Only a boundary survey by a Missouri-licensed professional land surveyor locates your corners on the ground.
Do I need a permit to build on river-bottom land in the county?
If the site is in a mapped floodplain, yes. The county requires a floodplain development permit, and an elevation certificate prepared by a licensed surveyor is commonly part of that process. Check the current FEMA map for your parcel before you plan any structure or fill.
