In most places the county maintains the parcel layer, and for this city that means the, especially near Coplay.Lehigh County ArcGIS parcel map.
Pulling up a parcel
Go first to the Lehigh County ArcGIS parcel map; it covers each tax parcel around Macungie and Coplay. If you only know roughly where the land is, follow US Route 222 on the aerial and select the outline. If you're looking near Emmaus, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Limits of the parcel data
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real boundary for a parcel near Fountain Hill. For a tract near Emmaus, records update in batches, so a deed recorded last month might lag behind.
Reading the legal description
Older tracts around Coplay are often described by metes and bounds, a series of courses and distances from a starting point. Town lots near Macungie usually use lot and block from a recorded plat instead, which is simpler to follow. Write down the legal description for the tract near Coplay for any title or survey request.
Where Allentown fits in
Allentown is part of Lehigh County, Pennsylvania, so its parcels are on the county's map. Allentown is also the county seat, which puts the Recorder of Deeds close by. On ground around Catasauqua, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the town limits near Catasauqua generally falls under county rules, not municipal ones.
Three ways to find a parcel
Vacant ground near Emmaus may lack an address, so zoom in from US Route 222 and click the outline. For land near Coplay, searching by parcel number never misses, and you'll find it on tax statements.
Neighboring parcel maps
Lehigh County borders Berks County, Bucks County, Carbon County, Montgomery County, and Northampton County; every one of them runs a separate parcel map. A tract near the line by Coplay can be split in two county records, so open the adjacent map before you assume the acreage.
