Land Surveyor in Chesterfield, Missouri
Surveying in Chesterfield, MO
Chesterfield is really two landscapes. Up on the bluffs, curving residential streets hold homes on wooded, sloping lots, many with drainage swales and retaining walls along the back line. Below the bluffs, Chesterfield Valley stretches flat toward the Missouri River, filled with retail centers, warehouses and newer commercial pads. A survey request from a homeowner off Clarkson Road looks nothing like one from a developer in the Valley, so we start by asking where the parcel sits and what the drawing is for.
The Valley's story is the levee. In July 1993 the Missouri River broke through the Monarch-Chesterfield Levee and put the Valley underwater. The levee was later rebuilt and raised to a far higher standard, and development returned on a large scale. Even so, much of the Valley and many of the city's streams are still mapped as FEMA special flood hazard areas, and the city requires a floodplain development permit before grading or building permits are issued there.
Chesterfield also draws a buffer around its flood zones. Its rules describe a Supplemental Protection Area that reaches beyond the mapped zone in the Valley, so a site just outside the shaded line can still need floodplain review. Work in a floodway needs a no-rise certification. For projects like these, we schedule a licensed land surveyor who knows St. Louis County records and Chesterfield's review process, confirm your price up front and deliver the signed survey with one invoice from us.

Chesterfield survey questions
My Chesterfield Valley site is behind the levee. Do I still need floodplain review?
Often, yes. Large parts of the Valley remain mapped as special flood hazard areas, and the city also reviews a supplemental area near those zones. Chesterfield wants a floodplain development permit approved before it releases grading or building permits, and a licensed surveyor's elevations are usually part of that file.
What is the Supplemental Protection Area in Chesterfield?
It is a city designation covering land outside the FEMA flood zone but close to it, measured from the zone boundary or from the 100-year high-water elevation in the Valley. Ask the city's public works staff whether your parcel falls inside it before you finalize plans.
I live on the bluffs, far from the river. Why would I need a survey?
Hillside lots bring their own questions: where the rear line falls in the trees, whether a deck or wall crosses a drainage easement, and how steep grades affect a pool or addition. A boundary or plot plan survey answers those before a contractor starts digging.
Where are Chesterfield deeds and plats recorded?
Chesterfield is in St. Louis County, so deeds, subdivision plats and recorded easements are filed with the St. Louis County Recorder of Deeds in Clayton. Your surveyor reviews those along with any earlier surveys of the lot.
