Weighing a property around Duquesne? Checking the McKeesport flood zone map reveals whether FEMA puts it in a high-risk zone, and no account is needed. This McKeesport guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Allegheny County ArcGIS parcel map.
Where the McKeesport flood zone map lives
Flood zones come from FEMA's Flood Map Service Center: type an address near Versailles, and pick the FIRMette or map view. A tract near White Oak without an address can still be found: search the nearest road and click the spot.
Where the parcel data lives
Begin with the Allegheny County ArcGIS parcel map; it maps every tax parcel in the county, Versailles included. Near Duquesne, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Glassport, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
McKeesport and the county around it
McKeesport sits in Allegheny County, Pennsylvania, and the county assessor maps its lots. Near Duquesne, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the town limits near Glassport often follows county rules, not municipal ones.
Low spots and local drainage
Creeks and ditches near Duquesne may not have detailed mapping, so walk the land after rain. Wet ground around Port Vue is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
What the map can't tell you
The acreage figure is an estimate; only a licensed surveyor can set the real corners for a parcel near Dravosburg. For a parcel near Port Vue, records update in batches, so a deed recorded last month might lag behind.
Decoding the flood zone labels
For a parcel near Duquesne, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a tract near Glassport, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Getting your bearings
Pittsburgh is the county seat, which is where the courthouse records live. Smaller places on the map include Port Vue, Versailles, Duquesne, and Glassport. Roughly 1,224,825 people call Allegheny County home (Census estimate, 2023) spread over about 730 square miles. Allegheny County was formed in 1788, and some chains of title near Port Vue are long. Features like Allegheny River and Monongahela River help you orient on the aerial around Versailles.
Sections, lots and bearings
Rural deeds near Dravosburg are often described by metes and bounds, a series of courses and distances from a starting point. Town lots near Glassport are typically described by lot and block, making them easier to find. Copy the legal description from the record for the parcel near Versailles before you request a deed or survey.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Allegheny County ArcGIS parcel map too to confirm you have the right parcel near Port Vue.
Deeds, plats and who keeps them
When the details count, pull the recorded deed from the Recorder of Deeds; the parcel map near Duquesne only summarizes it. Long-held tracts around White Oak can trace back through several deeds, and a title company can sort it out on a real sale.
Questions to ask before you buy
Ask the listing agent about past flood claims on the property near Glassport; an insurance quote early keeps the budget honest.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, which applies near Dravosburg as much as anywhere. New construction in a floodplain near Port Vue usually means extra permit review; call the permitting office early.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Versailles, though signal can drop in rural spots. A saved image of the lot near Versailles and its lines keeps working without signal.
