Weighing a property around Baldwin? The Franklin flood zone map tells you whether the lot falls inside a mapped floodplain, and the lookup is free. This Franklin guide covers: finding the address on FEMA's map, reading the zone codes, and matching it with the county parcel viewer.
Where the Franklin flood zone map lives
The official source is FEMA's Flood Map Service Center: type an address near Morgan City, then open the map view for that panel. A tract near Morgan City without an address can still be found: pan from the closest town and click inside the land.
Getting to the right map
Lots and tracts near Morgan City appear on the St. Mary Parish parcel viewer, a viewer that needs no account. For property near Morgan City, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Write down the parcel ID before closing the panel; every office in the parish will want it.
Franklin, LA: the basics
Franklin sits in St. Mary Parish, Louisiana, so its parcels are on the county's map. As the county seat, Franklin hosts the courthouse, handy when you need recorded documents. Out toward Morgan City, City or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the town limits near Baldwin generally follows county rules, not municipal ones.
The paper trail behind a parcel
For anything that matters, request the recorded deed from the Clerk of Court; the parcel map near Berwick only summarizes it. Long-held tracts in the parish can sit on many deeds, and a title company can sort it out if money is changing hands.
Reading A, AE and X
An AE label comes with a base flood elevation, while plain Zone A does not; builders around Morgan City design to it. If you're looking near Baldwin, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
A short flood checklist
Ask the seller for any Elevation Certificate on the property near Baldwin; getting a quote early keeps the budget honest.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Berwick, though signal can drop in rural spots. A screenshot of the parcel near Patterson with its ID is a good backup.
Next door to St. Mary Parish
St. Mary Parish meets Assumption Parish, Iberia Parish, St. Martin Parish, and Terrebonne Parish, and each of those keeps its own parcel map. A tract near the line by Patterson can show up in two parish records, so open the neighboring map before you assume the acreage. For land near Patterson, our state page lists every neighboring parish map across Louisiana.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the St. Mary Parish parcel viewer too for the outline of the tract near Patterson.
Getting answers from the right desk
Questions about value or the owner field for land near Morgan City go to the Parish Assessor, since that office keeps the assessment data. Questions about what you can build around Berwick go to planning, building or health offices, town or parish, depending on location.
Getting your bearings
Franklin holds the county offices, home to the main records offices. You'll also find Baldwin, Patterson, Berwick, and Morgan City, where town lots give way to larger tracts. About 47,055 people call St. Mary Parish home (Census estimate, 2023) spread over roughly 556 square miles. St. Mary Parish was formed in 1811, and some chains of title near Patterson are long. Features like Vermilion Bay and Cypremort Point State Park make handy reference points on the map near Morgan City.
Beyond the mapped zones
Creeks and ditches near Berwick may not have detailed mapping, so look for water marks and debris lines. Wetlands near Morgan City can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Lenders and permits
For property near Patterson, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. New construction in a floodplain near Berwick usually means extra permit review; check with the parish or town building office early.
