Trying to understand lot lines near Allentown? Start with the Emmaus plat map, since it shows lots, streets and easements as approved. In this Emmaus guide: where to request a copy, plat versus tax map, and what to look for on the sheet.
Who keeps the Emmaus plat map
For a subdivision near Macungie, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Getting to the right map
Go first to the Lehigh County ArcGIS parcel map; it maps each tax parcel from Allentown to Alburtis. For a tract near Catasauqua, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Catasauqua, write down the parcel ID before closing the panel; every office in the county asks for it first.
Metes and bounds instead
Rural land near Alburtis that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Macungie, but coverage can be spotty out of town. A printout of the tract near Alburtis is a good backup.
Where Emmaus fits in
Emmaus sits in Lehigh County, Pennsylvania, so its parcels are on the county's map. With a lot near Macungie, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits toward Alburtis usually falls under county rules instead.
Plat map vs. parcel map
The Lehigh County ArcGIS parcel map draws parcels for taxes, but the recorded plat is what the deed relies on.
Who handles what
If the acreage or value on a parcel near Catasauqua looks off go to the county assessment office, the office behind the parcel record. Building or septic questions for a lot near Coopersburg need the planning or permitting office, and the answer depends on jurisdiction.
A word on accuracy
Listed acreage is a tax-roll number; only a licensed surveyor can set the real lines for a parcel near Macungie. Out toward Fountain Hill, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Amended plats
An amended plat may change lots around Allentown, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Lehigh County in a few facts
Allentown serves as the county seat, which is where the courthouse records live. You'll also find Macungie, Alburtis, and Coopersburg. Around 377,754 people call Lehigh County home (Census Bureau estimate, 2023) spread over roughly 345 square miles. Lehigh County dates to 1812, and some chains of title near Coopersburg are long.
What a plat shows
Out toward Allentown, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements covering ground around Catasauqua sit with the Recorder of Deeds. For a home near Coopersburg, have ready the book and page shown in the record panel so staff can find the deed fast.
Getting a copy
In and around Coopersburg, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Next door to Lehigh County
Lehigh County touches Berks County, Bucks County, Carbon County, Montgomery County, and Northampton County, and each of those keeps its own parcel map. Ground near Alburtis that runs to the line may be split in two county records, so look at the neighboring map before you assume the acreage. Around Coopersburg, the Platbookmapper state page lists each neighboring county map across Pennsylvania.
Legal descriptions in Pennsylvania
Older tracts around Alburtis commonly use metes-and-bounds descriptions, which trace the boundary call by call. Town lots near Alburtis usually use lot and block from a recorded plat instead, making them easier to find. Keep the legal description for land near Alburtis when you talk to a surveyor.
