Towns in Scott County: Sikeston, Scott City, Chaffee.
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 Scott County has 78 FIRM panels, the newest effective June 2012; 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 Scott 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 Missouri county parcel layers (each county publishes its own), so a Scott lot shows the same lines the county assessor draws. Scott County covers about 268,808 acres of land and 3,746 acres of water.
Mapped lines are approximate. The Scott County assessor keeps the parcel record (Scott County website); a licensed surveyor sets the true corners.
Zoning
Scott County zones its unincorporated land, and Sikeston, Scott City, Chaffee each zone the land inside their limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning and zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Missouri's county planning and zoning law (Revised Statutes of Missouri Chapter 64), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Scott lot can add one depends on its district; the county planning and zoning office has the rule.
