Weighing a property around Callery? A quick look at the Butler County flood zone map shows whether it sits in a FEMA flood zone, and the lookup is free. What this Butler County guide covers: 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 Butler County flood zone map
For a more interactive look, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, and that holds around Callery too. Vacant ground around Chicora can still be found: zoom in from Interstate 79 then click the parcel area.
Opening the official parcel viewer
Begin with the PASDA Pennsylvania Tax Parcels viewer; it covers every assessed parcel from Fernway to Bruin. If you only know roughly where the land is, pan along Interstate 79 until the lines appear, then click inside the one you want. For a home near East Butler, save the parcel ID before closing the panel; every records desk in the county asks for it first.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near McConnells Mill State Park, so load it before you lose signal. A screenshot of the parcel near Connoquenessing with its ID keeps working without signal.
Reading A, AE and X
For land near Callery, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. On ground around East Butler, a low-risk label isn't a guarantee: according to FEMA, many claims come from moderate- and low-risk areas.
Next door to Butler County
Butler County touches Allegheny County, Armstrong County, Beaver County, Clarion County, and Lawrence County; every one of them runs a separate parcel map. Ground near McConnells Mill State Park that runs to the line may be split across two assessors' files, so check the neighboring map as well. For acreage around East Butler, the Platbookmapper state page lists each bordering county map across Pennsylvania.
Sections, lots and bearings
Older tracts around Bruin commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Town lots near Lake Arthur Estates 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 Meadowood before you request a deed or survey.
Lining it up with the parcel map
FEMA doesn't draw property lines, so open the PASDA Pennsylvania Tax Parcels viewer next for the outline of the tract near Meadowood.
Money questions tied to the zone
For a structure inside an A or V zone and the loan is federally backed or regulated, flood insurance is generally required where the community participates in the National Flood Insurance Program, for land near Moraine State Park included. Building or adding on near Forestville in a mapped zone can trigger elevation rules; ask the local floodplain administrator early.
Beyond the mapped zones
Creeks and ditches near Chicora aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Lake Arthur Estates can limit building too; check the National Wetlands Inventory mapper for a first look.
Questions to ask before you buy
On ground around Fernway, ask the listing agent about past flood claims before closing; an insurance quote early keeps the budget honest.
Limits of the parcel data
With a lot near Lake Arthur Estates, listed acreage is a tax-roll number; just a licensed surveyor establishes the real boundary on the ground. For a parcel near Moraine State Park, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Places you'll see on the map
Butler serves as the county seat, home to the main records offices. You'll also find Bruin, Callery, Cherry Valley, and Chicora, where town lots give way to larger tracts. Around 198,413 people call Butler County home (Census estimate, 2023) across roughly 789 square miles. Butler County was formed in 1800, and some chains of title near Lake Arthur Estates are long. Features like Slippery Rock Creek and Moraine State Park help you orient on the aerial.
Which office to call
Questions about value or the owner field for land near Connoquenessing are handled by the county assessment office, the office behind the parcel record. Zoning, permits and septic questions near Lake Arthur Estates need the planning or permitting office, and the answer depends on jurisdiction.

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.
