Free, no account. Or open the Virginia map and tap a lot.
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 24 FIRM panels covering Petersburg city, the newest effective May 2024; 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 Petersburg 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 Virginia statewide parcel layer (Virginia Geographic Information Network, from each locality), so a Petersburg lot shows the same lines the real estate assessor draws. Petersburg city covers about 14,541 acres of land and 143 acres of water.
Mapped lines are approximate. The Petersburg city real estate assessor keeps the parcel record (Petersburg city website); a licensed surveyor sets the true corners.
Zoning
In Petersburg city zoning is set by the city itself, an independent city outside any county. ParcelSheet shows the use code on the lot's parcel record and the municipality it sits in; the city planning office has the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Virginia's zoning law (Code of Virginia Title 15.2, Chapter 22), the city itself, an independent city outside any county can allow an accessory dwelling unit on a lot with a house. Whether a Petersburg lot can add one depends on its district; the city planning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Setbacks
Setbacks in Petersburg city come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the city planning office gives them for the lot's district.
