Before an offer near Enon Valley, look at the Lawrence County flood zone map: a mapped flood zone changes insurance, building rules and resale. Covered here for Lawrence County: the free FEMA tools, what each zone label means, lender insurance rules and how to challenge a map that looks wrong.
Getting started with the Lawrence County flood zone map
For a parcel near Mount Jackson, start with FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. A tract near New Wilmington without an address is still easy to locate: zoom in from US Route 19 and click the spot.
Pulling up a parcel
Go first to the Lawrence County ArcGIS parcel map; it maps every assessed parcel from New Bedford to Ellport. If you only know roughly where the land is, follow US Route 19 on the aerial and click the parcel itself, which applies near McConnells Mill State Park as much as anywhere. On ground around New Castle Northwest, copy the parcel ID from that panel; each office in the county will want it.
Limits of the parcel data
For a home near New Castle Northwest, listed acreage is a tax-roll number; only a licensed surveyor establishes the real boundary on the ground. Owner names and values update on a schedule, so a recent sale near Chewton may not show yet.
Questions to ask before you buy
On ground around Bessemer, ask the seller for any Elevation Certificate before closing; getting a quote early keeps the budget honest.
Decoding the flood zone labels
For a tract near Ellport, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. If the land is near Chewton, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the Lawrence County ArcGIS parcel map to see exactly which lot near Chewton you're looking at.
Who handles what
If the acreage or value on a parcel near New Wilmington looks off belong with the county assessment office, which maintains the tax roll. Questions about what you can build around Bessemer go to planning, building or health offices, town or county, depending on location.
Neighboring parcel maps
The county touches Columbiana County, OH, Mahoning County, OH, Beaver County, Butler County, and Mercer County; every one of them runs a separate parcel map, at least around Frizzleburg. Ground near Enon Valley that runs to the line can show up across two assessors' files, so open the adjacent map too. Around Frizzleburg, our state page links every neighboring county map across Pennsylvania.
What a flood zone means for a buyer
Out toward McConnells Mill State Park, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Mount Jackson in a mapped zone can trigger elevation rules; ask the local floodplain administrator early.
Water near New Bedford
Small streams around New Bedford may not have detailed mapping, so walk the land after rain. Wetlands near New Beaver can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Sections, lots and bearings
Older tracts around New Beaver commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Platted lots around New Castle Northwest refer to a recorded plat, which is simpler to follow. Copy the legal description from the record for the parcel near McConnells Mill State Park before you request a deed or survey.
Recorded documents worth pulling
In and around Mount Jackson, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county are filed with the Recorder of Deeds. For land near Mount Jackson, use the document number listed on the parcel record so staff can find the deed fast.
A quick look at the area
New Castle is the county seat, where most land records are kept. Other places on the map include Bessemer, Ellport, Ellwood City, and Enon Valley, where town lots give way to larger tracts. Around 84,472 people call Lawrence County home (Census Bureau estimate, 2023) across some 357 square miles. Lawrence County was formed in 1849, which matters when you trace an old farm's title. Landmarks such as McConnells Mill State Park help you orient on the aerial.

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.
