Weighing a property around Biglerville? The Gettysburg flood zone map tells you whether FEMA puts it in a high-risk zone, and it costs nothing to check. Covered here for Gettysburg: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the PASDA Pennsylvania Tax Parcels viewer.
Getting started with the Gettysburg flood zone map
Flood zones come from FEMA's Flood Map Service Center: type an address near Biglerville, then open the map view for that panel. Rural land near Arendtsville with no street number is still easy to locate: search the nearest road and click the spot.
Getting to the right map
Go first to the PASDA Pennsylvania Tax Parcels viewer; it includes every tax parcel around Biglerville and Arendtsville. Out toward Bonneauville, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Bonneauville, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Beyond the mapped zones
Low-lying fields near Bonneauville aren't always studied in detail, so walk the land after rain. Wet ground around Biglerville is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Legal descriptions in Pennsylvania
Rural deeds near Arendtsville commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Town lots near Carroll Valley usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near New Oxford for any title or survey request.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around New Oxford are filed with the Recorder of Deeds. Inherited tracts around Bonneauville can go back through a long string of deeds, and a title company can sort it out before a purchase.
Getting your bearings
Gettysburg holds the county offices, which is where the courthouse records live. Smaller places on the map include Bonneauville, Biglerville, Arendtsville, and Fairfield, each with its own cluster of lots. Around 106,748 people call Adams County home (Census Bureau estimate, 2023) across some 519 square miles. Adams County dates to 1800, so old deeds can run back a long way. Features like Caledonia State Park are easy to spot when you zoom out from Carroll Valley.
City limits and county records
Gettysburg lies within Adams County, Pennsylvania, so its parcels are on the county's map. As the county seat, Gettysburg hosts the courthouse, which puts the Recorder of Deeds close by. For acreage around Carroll Valley, 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. Land beyond the city limits near Arendtsville often falls under county rules, not municipal ones.
What the zone letters mean
If you're looking near Biglerville, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a home near New Oxford, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Offices that can help
Questions about value or the owner field for land near Arendtsville are handled by the county assessment office, since that office keeps the assessment data. Questions about what you can build around Biglerville need the planning or permitting office, and the answer depends on jurisdiction.
Field tips
Most viewers work in a phone browser, useful out on a road near Carroll Valley, but coverage can be spotty out of town. A saved image of the lot near Bonneauville and its lines keeps working without signal.
What to request from a seller
Ask the seller about past flood claims on the property near Carroll Valley; an insurance quote early avoids surprises.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the PASDA Pennsylvania Tax Parcels viewer to confirm you have the right parcel near Arendtsville.
Insurance, lenders and building
Out toward Fairfield, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Remodeling a house in a zone near Biglerville usually means extra permit review; ask the local floodplain administrator early.

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.
