Before you buy or build near Cornwall, pull up the Palmyra flood zone map: a mapped flood zone changes insurance, building rules and resale. In this Palmyra guide: finding the address on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Where the Palmyra flood zone map lives
Start with FEMA's Flood Map Service Center: search an address around Cornwall, and pick the FIRMette or map view. Vacant ground around Mount Gretna can still be found: search the nearest road then click the parcel area.
Getting to the right map
Your first stop is the Lebanon County ArcGIS parcel map; it covers each tax parcel in the county, Richland included. If you're looking near Cornwall, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For land near Lebanon, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements for land near Myerstown sit with the Recorder of Deeds. Older tracts around Myerstown can trace back through several deeds, and a title company earns its fee if money is changing hands.
City limits and county records
Palmyra lies within Lebanon County, Pennsylvania, which means parcel data comes from the county. For land near Cleona, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits toward Cleona generally falls under county rules instead.
Beyond the mapped zones
Low-lying fields near Myerstown aren't always studied in detail, so walk the land after rain. Marshy spots near Cornwall can limit building too; check the National Wetlands Inventory mapper for a first look.
A quick look at the area
Lebanon holds the county offices, where most land records are kept. Other places on the map include Cleona, Mount Gretna, and Cornwall, where town lots give way to larger tracts. Roughly 144,252 people call Lebanon County home (Census estimate, 2023) across some 362 square miles. Lebanon County was formed in 1813, and some chains of title near Mount Gretna are long.
Limits of the parcel data
The acreage figure is an estimate; only a licensed surveyor can set the real corners on land around Myerstown. For property near Mount Gretna, records update in batches, so a deed recorded last month might lag behind.
When a parcel crosses a boundary
Lebanon County borders Berks County, Dauphin County, Lancaster County, and Schuylkill County, and each of those keeps its own parcel map. Acreage along the edge near Cornwall may be split across two assessors' files, so check the neighboring map too. For property near Mount Gretna, our state page links each bordering county map across Pennsylvania.
Decoding the flood zone labels
An AE label includes a base flood elevation (BFE), and an unnumbered A zone has none; builders around Myerstown design to it. Near Myerstown, minimal risk is not no risk: according to FEMA, many claims come from moderate- and low-risk areas.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so open the Lebanon County ArcGIS parcel map next for the outline of the tract near Lebanon.
Reading the legal description
Older tracts around Cornwall are often described by metes and bounds, listing bearings, distances and landmarks. Town lots near Myerstown are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Cleona for any title or survey request.
Which office to call
For assessment questions about property around Cornwall belong with the county assessment office, since that office keeps the assessment data. Building or septic questions for a lot near Mount Gretna need the planning or permitting office, depending on whether the land is inside town limits.
What to request from a seller
Ask the listing agent for any Elevation Certificate for the house near Richland; getting a quote early keeps the budget honest.
Money questions tied to the zone
For property near Richland, get the Elevation Certificate if one exists: it can change the insurance price a lot. Remodeling a house in a zone near Myerstown usually means extra permit review; check with the county or town building 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.
