Ahead of any purchase around Crystal Lake Park, check the Des Peres flood zone map: a mapped flood zone changes insurance, building rules and resale. What this Des Peres guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the St. Louis County ArcGIS parcel map.
The Des Peres flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Town and Country with no street number is still easy to locate: search the nearest road then click the parcel area.
Where the parcel data lives
Your first stop is the St. Louis County ArcGIS parcel map; it maps every tax parcel around Huntleigh and Country Life Acres. If you only know roughly where the land is, zoom in from Crystal Lake Park until the lines appear, then click inside the one you want. Near Huntleigh, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
The paper trail behind a parcel
When the details count, request the recorded deed through the Recorder of Deeds; the parcel map near Kirkwood only summarizes it. Long-held tracts near Crystal Lake Park may go back through many deeds, and a title company can sort it out if money is changing hands.
Where Des Peres fits in
Des Peres sits in St. Louis County, Missouri, so its parcels are on the county's map. For a tract near Kirkwood, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the town limits toward Frontenac usually answers to county rules rather than the town's.
A word on accuracy
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Kirkwood often sits several feet off the line on screen. Records update in batches, so a recent sale near Huntleigh can take weeks to appear.
Zones on the Des Peres flood zone map
An AE label carries a published BFE, and an unnumbered A zone has none; that elevation drives building rules near Frontenac. Out toward Frontenac, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Neighboring parcel maps
St. Louis County borders Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County, all with their own assessor records. A tract near the line by Huntleigh may be split across two assessors' files, so check the adjacent map as well. If the land is near Kirkwood, our state page lists every neighboring county map across Missouri.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so open the St. Louis County ArcGIS parcel map next to see exactly which lot near Crystal Lake Park you're looking at.
Money questions tied to the zone
In and around Town and Country, get the Elevation Certificate if one exists: it compares the building to the BFE. Remodeling a house in a zone near Town and Country can trigger elevation rules; check with the county or town building office before you plan.
Getting answers from the right desk
Anything recorded against property around Huntleigh are with the Recorder of Deeds, often with an online index. Questions about what you can build around Town and Country go to planning, building or health offices, and the answer depends on jurisdiction.
Questions to ask before you buy
Request about past flood claims for the house near Country Life Acres; an insurance quote early keeps the budget honest.
Taking the map into the field

Water near Kirkwood
