Trying to size up a property near White Castle? Pulling up the Plaquemine GIS map gets you there fast, with no account needed. In this Plaquemine guide: where that map lives, how to search it, and the limits worth knowing.
Getting started with the Plaquemine GIS map
With a lot near Rosedale, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The viewer Iberville Parish publishes
The official parcel map for this area is the Iberville Parish parcel viewer, and anyone can open it without signing up. On ground around St. Gabriel, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Save the parcel ID while you have it open; each office in the parish asks for it first.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Rosedale are kept by the Clerk of Court. Long-held tracts in the parish may trace back through a long string of deeds, and a title company earns its fee if money is changing hands.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Grosse Tete, though signal can drop in rural spots. A printout of the tract near Grosse Tete helps when you meet an owner or agent.
Plaquemine, LA: the basics
Plaquemine sits in Iberville Parish, Louisiana, which means parcel data comes from the county. As the county seat, Plaquemine hosts the courthouse, which puts the Clerk of Court close by. For land near Rosedale, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the city limits toward St. Gabriel generally answers to county rules instead.
Offices that can help
For assessment questions about property around Maringouin are handled by the Parish Assessor, which maintains the tax roll. Building or septic questions for a lot near Rosedale need the planning or permitting office, town or parish, depending on location.
