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 parishwide study for Bossier Parish has 86 FIRM panels, the newest effective March 2013; 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 Bossier house comes from a licensed surveyor and is often on file with the parish or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Louisiana parish parcel layers (each parish publishes its own), so a Bossier lot shows the same lines the parish assessor draws. Bossier Parish covers about 537,357 acres of land and 17,468 acres of water.
Mapped lines are approximate. The Bossier Parish assessor keeps the parcel record (Bossier Parish website); a licensed surveyor sets the true corners.
Zoning
Bossier Parish zones its unincorporated land, and Bossier City zones the land inside its limits. ParcelSheet shows the use the parish assessor lists for the lot and links the parish planning and zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Louisiana's parish zoning law (Louisiana Revised Statutes 33:4780.40 and following), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Bossier lot can add one depends on its district; the parish planning and 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. Bossier Parish is soil survey area LA015, Bossier Parish, Louisiana, last updated September 2026, on Web Soil Survey.
