Towns in Acadia Parish: Crowley, Rayne, Church Point.
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 Acadia Parish has 23 FIRM panels, the newest effective November 2010; 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 an Acadia 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 an Acadia lot shows the same lines the parish assessor draws. Acadia Parish covers about 419,356 acres of land and 1,467 acres of water.
Mapped lines are approximate. The Acadia Parish assessor keeps the parcel record (Acadia Parish website); a licensed surveyor sets the true corners.
Zoning
Acadia Parish zones its unincorporated land, and Crowley, Rayne, Church Point each zone the land inside their 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 an Acadia 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
