Weighing a property around Smackover? The El Dorado flood zone map tells you whether FEMA puts it in a high-risk zone, and the lookup is free. This El Dorado guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Union County ArcGIS parcel map.
Getting started with the El Dorado flood zone map
The official source is FEMA's Flood Map Service Center: search an address around Smackover, and choose the dynamic map. Vacant ground around Junction City can still be found: pan from the closest town and click the spot.
Pulling up a parcel
Go first to the Union County ArcGIS parcel map; it covers each assessed parcel in the county, Calion included. Around Smackover, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For land near Huttig, the record panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
When a parcel crosses a boundary
Union County meets Ashley County, Bradley County, Calhoun County, Columbia County, and Ouachita County; every one of them runs a separate parcel map. A tract near the line by Huttig may show up across two assessors' files, so check the neighboring map too. For acreage around Norphlet, our state page links each bordering county map across Arkansas.
Getting your bearings
El Dorado serves as the county seat, where most land records are kept. You'll also find Norphlet, Calion, Smackover, and Junction City, where town lots give way to larger tracts. Roughly 37,397 people live in Union County (Census Bureau estimate, 2023) spread over about 1,039 square miles. Union County was formed in 1829, and some chains of title near Calion are long. Features like Ouachita River and Felsenthal National Wildlife Refuge are easy to spot when you zoom out from Huttig.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed through the Circuit Clerk; the parcel map near Huttig only summarizes it. Older tracts around Calion can sit on many deeds, and a title company can sort it out on a real sale.
A short flood checklist
Ask the listing agent for any Elevation Certificate for the house near Huttig; an insurance quote early keeps the budget honest.
Where El Dorado fits in
El Dorado sits in Union County, Arkansas, and the county assessor maps its lots. As the county seat, El Dorado hosts the courthouse, handy when you need recorded documents. For a home near Calion, City or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the town limits toward Norphlet generally answers to county rules instead.
What the zone letters mean
An AE label carries a published BFE, and an unnumbered A zone has none; surveyors near Strong use that number. For land near Strong, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Low spots and local drainage
Low-lying fields near Norphlet may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Smackover can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so pair it with the Union County ArcGIS parcel map to confirm you have the right parcel near Norphlet.
Money questions tied to the zone
For acreage around Norphlet, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Strong usually means extra permit review; check with the county or town building office early.
Limits of the parcel data
Acreage on the record is a tax-roll number; just a licensed surveyor can set the real lines for a parcel near Calion. Records update in batches, so a recent sale near Calion might lag behind.
Who handles what
If the acreage or value on a parcel near Smackover looks off go to the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Smackover go to planning, building or health offices, town or county, depending on location.

Is AE a high-risk flood zone near Huttig?
Good question; an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near Calion design to that elevation.
What is a base flood elevation in El Dorado?
Good question; a BFE near Junction City tells builders how high the lowest floor should be; surveyors near Strong use it often.
What is a LOMA around Calion?
You can ask FEMA for a LOMA if surveyed elevations show the building near Huttig is above the BFE; it starts with an elevation survey.
When is flood insurance required in El Dorado?
Short answer: for a building near Calion in an A or V zone with a federally backed or regulated mortgage, it's generally required; elsewhere it's optional.
Is the parcel map a survey around Calion?

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
