Towns in Schuyler County: Rushville.
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's countywide study for Schuyler County has 23 FIRM panels, the newest effective September 2015; 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 Schuyler 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 Schuyler lot shows the same lines the county supervisor of assessments draws. Schuyler County covers about 279,872 acres of land and 2,597 acres of water.
Mapped lines are approximate. The Schuyler County supervisor of assessments keeps the parcel record (Schuyler County website); a licensed surveyor sets the true corners.
Zoning
Schuyler County zones its unincorporated land, and Rushville 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.

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 Schuyler 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
