Ahead of any purchase around Fountain Hill, look at the Emmaus flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for Emmaus: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Getting started with the Emmaus flood zone map
Flood zones come from FEMA's Flood Map Service Center: type an address near Fountain Hill, then open the map view for that panel. A tract near Coopersburg without an address is still easy to locate: pan from the closest town then click the parcel area.
Pulling up a parcel
Property in and around Coopersburg can be looked up on the Lehigh County ArcGIS parcel map, free to use and open without a login. When a rural tract has no street number, pan along US Route 222 and select the outline. For a parcel near Macungie, the parcel card typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Legal descriptions in Pennsylvania
Older tracts around Alburtis are often described by metes and bounds, a series of courses and distances from a starting point. Subdivision lots in Alburtis usually use lot and block from a recorded plat instead, which is simpler to follow. Write down the legal description for the tract near Alburtis for any title or survey request.
A word on accuracy
The acreage figure is a tax-roll number; only a licensed surveyor establishes the real boundary for a parcel near Coopersburg. On ground around Macungie, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Emmaus, PA: the basics
Emmaus is part of Lehigh County, Pennsylvania, which means parcel data comes from the county. With a lot near Allentown, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits near Macungie generally follows county rules rather than the town's.
What to request from a seller
Request about past flood claims on the property near Catasauqua; an insurance quote early keeps the budget honest.
Decoding the flood zone labels
An AE label comes with a base flood elevation, while plain Zone A does not; builders around Alburtis design to it. If the land is near Alburtis, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Lining it up with the parcel map
FEMA doesn't draw property lines, so check the Lehigh County ArcGIS parcel map too for the outline of the tract near Fountain Hill.
Who handles what
If the acreage or value on a parcel near Macungie looks off are handled by the county assessment office, since that office keeps the assessment data. Building or septic questions for a lot near Alburtis need the planning or permitting office, town or county, depending on location.
Neighboring parcel maps
Lehigh County touches Berks County, Bucks County, Carbon County, Montgomery County, and Northampton County; every one of them runs a separate parcel map. Ground near Allentown that runs to the line may show up in two county records, so check the neighboring map before you assume the acreage. Near Catasauqua, our state page links every bordering county map across Pennsylvania.
Water near Fountain Hill
Low-lying fields near Macungie may not have detailed mapping, so walk the land after rain. Marshy spots near Catasauqua can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
A quick look at the area
Allentown holds the county offices, which is where the courthouse records live. You'll also find Macungie, Alburtis, and Coopersburg, where town lots give way to larger tracts. Around 377,754 people call Lehigh County home (Census Bureau estimate, 2023) on about 345 square miles. Lehigh County dates to 1812, so old deeds can run back a long way.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Fountain Hill sit with the Recorder of Deeds. Long-held tracts around Catasauqua may trace back through a long string of deeds, and a title company can sort it out on a real sale.
Insurance, lenders and building
On ground around Allentown, get the Elevation Certificate if one exists: it can change the insurance price a lot. New construction in a floodplain near Catasauqua often needs a floodplain permit; call the permitting office before you plan.

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.
