Is that lot in Bedford in a flood zone? The Pike County flood zone map answer comes from FEMA, and it's free to look up. For any tract in Pike County, Illinois, the answer affects insurance, permits and resale.
We'll cover finding a Pike County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
Where to see the official Pike County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Atlas. If a parcel near Pittsfield has no street number yet, search the nearest road and pan to it. On acreage outside Atlas, try FEMA's National Flood Hazard Layer viewer and reports the zone wherever you click near Atlas. Switch to the Pike County WTH GIS map and locate the same parcel near Pittsfield. Match the Pike County lines and acreage to the FEMA view, since flood maps don't draw property lines in detail.
Opening the Pike County parcel viewer
For land around Pittsfield, open the Pike County WTH GIS map (a WTH Technology GIS parcel site); it's the map Pike County itself publishes. Click any Pike County parcel near Atlas to open its record: owner, parcel ID and assessed acreage are generally listed. For a backup route to the map covering Pittsfield, our Pike County directory entry keeps the link current.
What the flood zone letters mean
On the FIRM covering Pike County, zones that start with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). Zone AE near Pittsfield means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a Pike County parcel shows shaded Zone X, it falls between the base flood and the 500-year flood. Unshaded Zone X near Pittsfield is minimal risk.
Recorded documents in Pike County, Illinois
The parcel layer for Pike County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). A deed book and page or instrument number on the county record is the fastest way to order the document for a lot in Bedford.

Low ground and small streams around Atlas
Small streams and ditches near Atlas may not be studied in detail, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
Insurance, permits and map changes
The zone shows up again when a loan on a house near Pittsfield is underwritten. When a Pike County home falls inside an A or V zone and is financed by a regulated or federally insured lender, the lender must require flood coverage under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a Pike County home in shaded or unshaded X, insurance is a choice, not a mandate, although some lenders require it anyway. When a Pike County homesite is on a rise inside a mapped zone, FEMA's LOMA process allows a review, supported by elevation data from a professional surveyor. Building or filling inside a mapped zone near Atlas generally needs a floodplain permit; the county floodplain administrator can say what applies.
Quick answers for Pike County
Is there a floodplain layer in the Pike County WTH GIS map?
Check the layer list in the Pike County WTH GIS map; if Pike County includes a floodplain layer, confirm the zone on FEMA's map anyway.
Who prepares an elevation certificate for a house in Atlas?
A professional surveyor or engineer prepares it, and the building office serving Atlas may already have one on file for newer construction.

Building in a Special Flood Hazard Area near Atlas generally needs a floodplain permit and may require elevating the structure, so check with the county floodplain administrator.
My lot in Atlas shows Zone AE. What does that mean?
For a Pike County parcel, Zone AE means a Special Flood Hazard Area with a 1-percent annual chance of flooding and a published base flood elevation.

Not at all; a Pike County tract in that zone carries a 1-in-100 chance in any single year, not a once-a-century schedule.
