Weighing a property around Hummelstown? Checking the Middletown flood zone map reveals whether it sits in a FEMA flood zone, and it costs nothing to check. What this Middletown guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the PASDA Pennsylvania Tax Parcels viewer.
The Middletown flood zone map: start here
The official source is FEMA's Flood Map Service Center: type an address near Royalton, and pick the FIRMette or map view. Vacant ground around Highspire can still be found: zoom in from Interstate 81 and click the spot.
The free map to start with
Parcels around Paxtang appear on the PASDA Pennsylvania Tax Parcels viewer, which opens without registering. If you only know roughly where the land is, pan along Interstate 81 until the lines appear, then click inside the one you want. If you're looking near Paxtang, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Neighboring parcel maps
Dauphin County touches Cumberland County, Juniata County, Lancaster County, Lebanon County, and Northumberland County, all with their own assessor records. A tract near the line by Penbrook can be split in two county records, so look at the neighboring map too. If you're looking near Penbrook, our state page lists each neighboring county map across Pennsylvania.
City limits and county records
Middletown is part of Dauphin County, Pennsylvania, which means parcel data comes from the county. For acreage around Royalton, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits near Steelton usually falls under county rules rather than the town's.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near Steelton may sit a few yards off the line on screen. For property near Royalton, records update in batches, so a deed recorded last month can take weeks to appear.
Zones on the Middletown flood zone map
Zone AE comes with a base flood elevation, while plain Zone A does not; builders around Hummelstown design to it. Closer to Steelton, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so open the PASDA Pennsylvania Tax Parcels viewer next to see exactly which lot near Steelton you're looking at.
Lenders and permits
With a lot near Steelton, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Steelton can trigger elevation rules; check with the county or town building office early.
Questions to ask before you buy
Request for any Elevation Certificate for the house near Royalton; getting a quote early avoids surprises.
Water near Royalton
Creeks and ditches near Hummelstown aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Penbrook is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Field tips
Most viewers work in a phone browser, useful out on a road near Highspire, so load it before you lose signal. A screenshot of the parcel near Steelton with its ID keeps working without signal.
Sections, lots and bearings
Rural deeds near Highspire are often described by metes and bounds, which trace the boundary call by call. Subdivision lots in Hummelstown refer to a recorded plat, making them easier to find. Keep the legal description for land near Steelton when you talk to a surveyor.
