Before an offer near Crystal Lake Park, check the Town and Country flood zone map: FEMA's zone label affects insurance, permits and resale. In this Town and Country guide: the free FEMA tools, what each zone label means, when insurance is required and what a LOMA is.
The Town and Country flood zone map: start here
The official source is FEMA's Flood Map Service Center: type an address near Crystal Lake Park, then open the map view for that panel. Vacant ground around Westwood can still be found: zoom in from Interstate 64 and click inside the land.
Pulling up a parcel
Begin with the St. Louis County ArcGIS parcel map; it covers every assessed parcel around Crystal Lake Park and Westwood. For a parcel near Crystal Lake Park, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Des Peres, write down the parcel ID from that panel; each office in the county will want it.
City limits and county records
Town and Country lies within St. Louis County, Missouri, so its parcels are on the county's map. For a home near Des Peres, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits out by Country Life Acres usually answers to county rules instead.
What the zone letters mean
Around Creve Coeur, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. Around Crystal Lake Park, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Sections, lots and bearings
Missouri is laid out under the Public Land Survey System, so rural legal descriptions near Crystal Lake Park cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Country Life Acres can be irregular. Keep the legal description for land near Country Life Acres when you talk to a surveyor.
A short flood checklist
Ask the listing agent whether the home has flooded on the property near Country Life Acres; getting a quote early avoids surprises.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the St. Louis County ArcGIS parcel map to confirm you have the right parcel near Frontenac.
What a flood zone means for a buyer
With a lot near Westwood, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Des Peres in a mapped zone often needs a floodplain permit; call the permitting office before you plan.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Westwood, though signal can drop in rural spots. A printout of the tract near Country Life Acres helps when you meet an owner or agent.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed from the Recorder of Deeds; the parcel map near Frontenac only summarizes it. Inherited tracts near Frontenac can sit on a long string of deeds, and a title company is worth hiring before a purchase.
Low spots and local drainage
Creeks and ditches near Des Peres aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Country Life Acres can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Offices that can help
Questions about value or the owner field for land near Creve Coeur are handled by the County Assessor, the office behind the parcel record. Questions about what you can build around Des Peres go to planning, building or health offices, depending on whether the land is inside town limits.
Neighboring parcel maps
St. Louis County touches Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County; every one of them runs a separate parcel map. Ground near Frontenac that runs to the line can show up across two assessors' files, so open the adjacent map too. For acreage around Creve Coeur, the Platbookmapper state page lists every bordering county map across Missouri.
