Before an offer near Freeport, pull up the Harrison County flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for Harrison County: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
The Harrison County flood zone map: start here
If you'd rather pan and zoom, try the National Flood Hazard Layer viewer, where zone shading sits over a photo base, and that holds around Conotton too. Rural land near Cadiz with no street number can still be found: zoom in from the nearest road and click inside the land.
Where the parcel data lives
Lots and tracts near Harrisville are published on the Ohio Statewide Parcels layer in ArcGIS Map Viewer, which opens without registering. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, whether the land is near Adena or elsewhere in the county. For property near Bowerston, write down the parcel ID before closing the panel; every records desk in the county will want it.
A short flood checklist
For acreage around Cadiz, ask the seller about past flood claims before closing; an insurance quote early keeps the budget honest.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Hopedale, but coverage can be spotty out of town. A printout of the tract near Conotton helps when you meet an owner or agent.
Reading A, AE and X
In and around Adena, A and V zones mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. For property near Tippecanoe, shaded Zone X is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Ohio Statewide Parcels layer in ArcGIS Map Viewer to see exactly which lot near Harrisville you're looking at.
Who handles what
For assessment questions about property around Deersville belong with the County Auditor, which maintains the tax roll. Questions about what you can build around Conotton go to planning, building or health offices, town or county, depending on location.
The paper trail behind a parcel
When the details count, request the recorded deed through the County Recorder; the parcel line is a drawing of it, and that holds around Harrisville too. With a lot near East Cadiz, older tracts in the county can go back through several deeds, and a title company earns its fee if money is changing hands.
Limits of the parcel data
For land near Tippecanoe, listed acreage is a tax-roll number; just a licensed surveyor establishes the real boundary on the ground. For a tract near Bowerston, records update in batches, so a deed recorded last month can take weeks to appear.
How land is described here
Tracts outside towns near Freeport commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in Cadiz are typically described by lot and block, making them easier to find. Keep the legal description for land near Cadiz for any title or survey request.
Harrison County in a few facts
Cadiz holds the county offices, home to the main records offices. You'll also find Adena, Bowerston, Deersville, and Freeport, where town lots give way to larger tracts. About 14,159 people live in Harrison County (Census Bureau estimate, 2023) across about 402 square miles. Harrison County dates to 1813, which matters when you trace an old farm's title.
Beyond the mapped zones
Creeks and ditches near Deersville may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Georgetown can limit building too; check the National Wetlands Inventory mapper for a first look.
Lenders and permits
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, flood insurance is generally required where the community participates in the National Flood Insurance Program, and that holds around Conotton too. New construction in a floodplain near East Cadiz often needs a floodplain permit; check with the county or town building office early.
