When land near Baldwin catches your eye, a look at the Morgan City GIS map gives you the outline, the owner of record and a parcel ID. What this Morgan City guide covers: which viewer to open, how to search it, and what to double-check with records.
Getting started with the Morgan City GIS map
For a parcel near Patterson, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Pulling up a parcel
Begin with the St. Mary Parish parcel viewer; it maps each tax parcel around Franklin and Patterson. With a lot near Franklin, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. Write down the parcel ID from that panel; every office in the parish will want it.
Places you'll see on the map
Franklin is the county seat, where most land records are kept. You'll also find Berwick, Patterson, and Baldwin, where town lots give way to larger tracts. About 47,055 people live in St. Mary Parish (Census estimate, 2023) spread over about 556 square miles. St. Mary Parish dates to 1811, so old deeds can run back a long way. Features like Vermilion Bay and Cypremort Point State Park are easy to spot when you zoom out from Berwick.
What the map can't tell you
The acreage figure is an assessed number; just a licensed surveyor can set the real corners for a parcel near Baldwin. If the land is near Berwick, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Berwick, though signal can drop in rural spots. A screenshot of the parcel near Baldwin with its ID keeps working without signal.
Browser tips
When the map won't open around Berwick, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Land on the parish line
St. Mary Parish touches Assumption Parish, Iberia Parish, St. Martin Parish, and Terrebonne Parish; every one of them runs a separate parcel map. A tract near the line by Berwick may show up in two parish records, so open the adjacent map as well. Our state page links every neighboring parish map across Louisiana.
Saving what you find
Print or screenshot the parcel near Patterson with its ID visible, so you have it when calling an office.
Deeds, plats and who keeps them
For anything that matters, get the recorded deed through the Clerk of Court; the parcel map near Patterson only summarizes it. Older tracts in the parish can sit on many deeds, and a title company can sort it out on a real sale.
Morgan City, LA: the basics
Morgan City sits in St. Mary Parish, Louisiana, which means parcel data comes from the county. Local government in Morgan City handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits out by Franklin generally falls under county rules rather than the town's.
Which office to call
If the acreage or value on a parcel near Berwick looks off go to the Parish Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Patterson go to planning, building or health offices, town or parish, depending on location.
Searching the map
Addresses are the easiest route inside Morgan City; owner search often wants the surname first. If you're looking near Franklin, searching by parcel number never misses, and you'll find it on tax statements.

Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Patterson can be irregular. Write down the legal description for the tract near Berwick for any title or survey request.
