Old copies of the Acadia Parish plat book turn up at auctions and in kitchen drawers around Estherwood, and new ones are harder to track down. Here's what a plat book is, where to look for one in Acadia Parish, and the free official map that stays current between editions.
Plat books vs. recorded plats in Acadia Parish
A plat book, sometimes called a land atlas, lists each township in Acadia Parish as a page, with ownership blocks labeled by owner name and approximate acreage. It's different from a recorded plat, which is the official survey drawing for a subdivision in Estherwood filed with the parish.
Step one: the free Acadia Parish viewer
The parish's own public map is the Acadia Parish ArcGIS parcel map, built on an Esri ArcGIS web map, and it opens without an account for parcels in Crowley and the rest of the parish. Most people track down their Acadia Parish tract fastest by searching an address in Eunice, then clicking the outline. For a backup route to the map covering Eunice, our Acadia Parish directory entry keeps the link current.
Finding a printed Acadia Parish plat book
Try the library in Estherwood or a local historical society for older Acadia Parish editions; libraries sometimes keep past atlases for reference. Older editions are useful for family history around Eunice, showing who held a farm decades ago.
Atlas details and limits
Many atlases add rural residence listings and road maps, handy on back roads near Egan. Acreage printed in a parish atlas is approximate; the deed and a survey decide the real figure for a tract near Basile. If you use a plat book for hunting permission near Estherwood, recheck the landowner on the parish map first.
Making your own atlas of Acadia Parish
Names in an older Acadia Parish atlas can lead you to the right deed in the grantor-grantee index for land near Egan. Saving PDFs of the parish map around Egan gives you an offline reference when the signal drops.
What drives land use around Crowley
