Free, no account. Or open the Illinois map and tap a lot.
Towns in Bond County: Greenville.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA has 3 FIRM panels covering Bond County, the newest effective August 2007; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Bond house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Illinois county parcel layers (each county publishes its own), so a Bond lot shows the same lines the county supervisor of assessments draws. Bond County covers about 243,415 acres of land and 1,597 acres of water.
Mapped lines are approximate. The Bond County supervisor of assessments keeps the parcel record (Bond County website); a licensed surveyor sets the true corners.
Zoning
Bond County zones its unincorporated land, and Greenville zones the land inside its limits. ParcelSheet shows the use the county supervisor of assessments lists for the lot and links the county zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Illinois's county zoning law (Counties Code, 55 ILCS 5/5-12001 and following), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Bond lot can add one depends on its district; the county zoning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Bond County is soil survey area IL005, Bond County, Illinois, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Bond County needs a permit from the Bond County health department (Illinois Department of Public Health private sewage program; IDPH itself where the county has no health department).
