Before you buy or build near Pitcairn, pull up the Monroeville flood zone map: FEMA's zone label affects insurance, building rules and resale. Covered here for Monroeville: finding the address on FEMA's map, reading the zone codes, and pairing it with the Allegheny County ArcGIS parcel map.
Where the Monroeville flood zone map lives
Start with FEMA's Flood Map Service Center: search an address around Pitcairn, and pick the FIRMette or map view. Vacant ground around East McKeesport is still easy to locate: zoom in from Interstate 376 then click the parcel area.
Where the parcel data lives
Your first stop is the Allegheny County ArcGIS parcel map; it covers each assessed parcel from Trafford to Turtle Creek. Near Trafford, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Wilmerding, write down the parcel ID from that panel; every clerk in the county will want it.
How land is described here
Older tracts around East McKeesport commonly use metes-and-bounds descriptions, which trace the boundary call by call. Subdivision lots in Turtle Creek usually use lot and block from a recorded plat instead, making them easier to find. Keep the legal description for land near East McKeesport for any title or survey request.
City limits and county records
Monroeville is part of Allegheny County, Pennsylvania, and the county assessor maps its lots. Local government in Monroeville handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the town limits near Turtle Creek usually follows county rules, not municipal ones.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Trafford, so load it before you lose signal. A saved image of the lot near Wilmerding and its lines keeps working without signal.
What to request from a seller
Request about past flood claims for the house near Wilmerding; an insurance quote early avoids surprises.
Who handles what
If the acreage or value on a parcel near Pitcairn looks off are handled by the county assessment office, which maintains the tax roll. Questions about what you can build around Wall are for the local planning and health departments, depending on whether the land is inside town limits.
A quick look at the area
Pittsburgh serves as the county seat, where most land records are kept. Smaller places on the map include Pitcairn, Wall, Trafford, and Wilmerding, where town lots give way to larger tracts. Around 1,224,825 people call Allegheny County home (Census Bureau estimate, 2023) spread over some 730 square miles. Allegheny County dates to 1788, and some chains of title near Wall are long. Landmarks such as Allegheny River and Monongahela River are easy to spot when you zoom out from Wilmerding.
Zones on the Monroeville flood zone map
If the land is near Wall, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. Around East McKeesport, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Allegheny County ArcGIS parcel map too for the outline of the tract near Wall.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements for land near Turtle Creek sit with the Recorder of Deeds. For a parcel near Wall, have ready the instrument number shown in the record panel to skip a name search.
Land on the county line
Allegheny County touches Armstrong County, Beaver County, Butler County, Washington County, and Westmoreland County, and each of those keeps its own parcel map. Acreage along the edge near East McKeesport may be split across two assessors' files, so open the neighboring map too. If the land is near Pitcairn, our state page links every bordering county map for Pennsylvania.
Beyond the mapped zones
Low-lying fields near East McKeesport aren't always studied in detail, so walk the land after rain. Wetlands near Wilmerding can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
What a flood zone means for a buyer
For a tract near East McKeesport, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Remodeling a house in a zone near East McKeesport often needs a floodplain permit; call the permitting office before you plan.
