Ahead of any purchase around McDermott, look at the Scioto County flood zone map: the zone on that map shapes insurance, building rules and resale. In this Scioto County guide: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Ohio Statewide Parcels layer in ArcGIS Map Viewer.
Checking the Scioto County flood zone map step by step
If you'd rather pan and zoom, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, for land near Wayne National Forest included. Vacant ground around New Boston is still easy to locate: zoom in from the nearest road and click the spot.
Getting to the right map
Begin with the Ohio Statewide Parcels layer in ArcGIS Map Viewer; it covers every tax parcel around New Boston and Franklin Furnace. Without an address in hand, zoom in from Wayne National Forest and select the outline. With a lot near South Webster, write down the parcel ID from that panel; every records desk in the county uses it to find the file.
Getting answers from the right desk
Anything recorded against property around Portsmouth are with the County Recorder, usually searchable by name or document number. Building or septic questions for a lot near Rarden need the planning or permitting office, and the answer depends on jurisdiction.
Land on the county line
Scioto County meets Greenup County, KY, Lewis County, KY, Adams County, Jackson County, and Lawrence County, and each of those keeps its own parcel map. Acreage along the edge near New Boston can be split in two county records, so look at the neighboring map before you assume the acreage. For property near Friendship, our state page lists every neighboring county map for Ohio.
A short flood checklist
Ask the listing agent about past flood claims on the property near Shawnee State Park; getting a quote early keeps the budget honest.
Low spots and local drainage
Creeks and ditches near Rarden aren't always studied in detail, so walk the land after rain. Wet ground around Franklin Furnace is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
What the zone letters mean
Zone AE comes with a base flood elevation, and an unnumbered A zone has none; surveyors near South Webster use that number. For a home near Franklin Furnace, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Getting your bearings
Portsmouth is the county seat, which is where the courthouse records live. Other places on the map include New Boston, Otway, Rarden, and South Webster. Around 71,969 people live in Scioto County (Census estimate, 2023) across roughly 610 square miles. Scioto County was formed in 1803, so old deeds can run back a long way. Features like Shawnee State Park make handy reference points on the map.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements covering ground around Wayne National Forest are filed with the County Recorder. For land near New Boston, have ready the document number from the tax record and the lookup takes minutes.
What the map can't tell you
Acreage on the record is an estimate; only a licensed surveyor can set the real corners for a parcel near Shawnee State Park. On ground around Rarden, records update in batches, so a deed recorded last month can take weeks to appear.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Friendship, so load it before you lose signal. A saved image of the lot near New Boston and its lines helps when you meet an owner or agent.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so open the Ohio Statewide Parcels layer in ArcGIS Map Viewer next to see exactly which lot near McDermott you're looking at.
Money questions tied to the zone
For property near South Webster, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Lucasville in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
