Weighing a property around Nederland? Checking the Port Arthur flood zone map reveals whether the lot falls inside a mapped floodplain, and it costs nothing to check. What this Port Arthur guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Jefferson County ArcGIS parcel map.
Checking the Port Arthur flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: search an address around Groves, then open the map view for that panel. A tract near Bevil Oaks without an address can still be found: zoom in from US Route 96 then click the parcel area.
Where the parcel data lives
Your first stop is the Jefferson County ArcGIS parcel map; it maps every tax parcel from Taylor Landing to Groves. Without an address in hand, follow US Route 96 on the aerial and click the parcel itself. For a home near Taylor Landing, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Bevil Oaks, though signal can drop in rural spots. A printout of the tract near Nederland helps when you meet an owner or agent.
Who handles what
If the acreage or value on a parcel near Groves looks off belong with the appraisal district, the office behind the parcel record. Zoning, permits and septic questions near Groves are for the local planning and health departments, town or county, depending on location.
Port Arthur, TX: the basics
Port Arthur is part of Jefferson County, Texas, and the county assessor maps its lots. For property near Port Neches, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits out by Nederland usually falls under county rules rather than the town's.
Reading A, AE and X
An AE label includes a base flood elevation (BFE), which plain A zones lack; builders around Port Neches design to it. On ground around Groves, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Reading the legal description
Older tracts around Groves are often described by metes and bounds, listing bearings, distances and landmarks. Platted lots around Bevil Oaks refer to a recorded plat, making them easier to find. Keep the legal description for land near Port Neches when you talk to a surveyor.
Lining it up with the parcel map
FEMA doesn't draw property lines, so pair it with the Jefferson County ArcGIS parcel map to see exactly which lot near Groves you're looking at.
What a flood zone means for a buyer
For a parcel near Taylor Landing, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Bevil Oaks often needs a floodplain permit; check with the county or town building office early.
Questions to ask before you buy
Request whether the home has flooded on the property near Nederland; getting a quote early avoids surprises.
Neighboring parcel maps
Jefferson County borders Cameron Parish, LA, Chambers County, Hardin County, Liberty County, and Orange County, all with their own assessor records. Ground near Bevil Oaks that runs to the line may be split in two county records, so open the adjacent map as well. For a home near Bevil Oaks, our state page lists every neighboring county map across Texas.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor can set the real boundary for a parcel near Port Neches. Closer to Beaumont, records update in batches, so a deed recorded last month might lag behind.
Beyond the mapped zones
Small streams around Port Neches aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Port Neches can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Getting your bearings
Beaumont holds the county offices, where most land records are kept. You'll also find Groves, Port Neches, Nederland, and Taylor Landing. Around 251,496 people live in Jefferson County (Census Bureau estimate, 2023) on about 877 square miles. Jefferson County was organized in 1837, and some chains of title near Beaumont are long. Features like Pine Island Bayou, Neches River, and Sea Rim State Park are easy to spot when you zoom out from Bevil Oaks.
