Before you buy or build near Beaumont, pull up the Port Neches flood zone map: a mapped flood zone changes insurance, permits and resale. What this Port Neches guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Jefferson County ArcGIS parcel map.
Checking the Port Neches flood zone map step by step
The official source is FEMA's Flood Map Service Center: search an address around Bevil Oaks, and choose the dynamic map. Vacant ground around Beaumont can still be found: zoom in from US Route 96 and click inside the land.
The free map to start with
Go first to the Jefferson County ArcGIS parcel map; it covers each assessed parcel from Bevil Oaks to Taylor Landing. For acreage around Taylor Landing, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Closer to Port Arthur, the record panel usually lists the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Next door to Jefferson County
Jefferson County touches Cameron Parish, LA, Chambers County, Hardin County, Liberty County, and Orange County; every one of them runs a separate parcel map. A tract near the line by Nederland can be split across two assessors' files, so check the adjacent map before you assume the acreage. If the land is near Bevil Oaks, our state page lists each bordering county map for Texas.
Getting your bearings
Beaumont is the county seat, which is where the courthouse records live. You'll also find Nederland, Groves, Port Arthur, and Taylor Landing, where town lots give way to larger tracts. About 251,496 people call Jefferson County home (Census Bureau estimate, 2023) spread over roughly 877 square miles. The county dates to 1837, and some chains of title near Nederland are long. Features like Pine Island Bayou, Neches River, and Sea Rim State Park are easy to spot when you zoom out from Nederland.
Port Neches, TX: the basics
Port Neches lies within Jefferson County, Texas, and the county assessor maps its lots. With a lot near Beaumont, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits toward Nederland generally answers to county rules rather than the town's.
Questions to ask before you buy
Request for any Elevation Certificate for the house near Beaumont; an insurance quote early avoids surprises.
Beyond the mapped zones
Low-lying fields near Groves may not have detailed mapping, so look for water marks and debris lines. Wetlands near Port Arthur can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
What the zone letters mean
With a lot near Taylor Landing, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. Around Groves, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
How land is described here
Tracts outside towns near Bevil Oaks are often described by metes and bounds, which trace the boundary call by call. Town lots near Port Arthur are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Port Arthur when you talk to a surveyor.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Nederland, but coverage can be spotty out of town. A printout of the tract near Nederland is a good backup.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around Beaumont are filed with the County Clerk. Older tracts around Beaumont can go back through many deeds, and a title company earns its fee if money is changing hands.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Jefferson County ArcGIS parcel map too for the outline of the tract near Bevil Oaks.
Money questions tied to the zone
For a tract near Beaumont, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Remodeling a house in a zone near Groves often needs a floodplain permit; call the permitting office before you plan.
Port Neches: common questions
Do I need flood insurance in Port Neches?
In most cases, for a building near Bevil Oaks in an A or V zone with a federally backed or regulated mortgage, it's generally required, in communities that take part in the NFIP.
Is there a flood layer on the parcel viewer near Nederland?
It depends, but a flood layer may appear in the Jefferson County ArcGIS parcel map layer list, but FEMA's own map is the official source.
Is AE a high-risk flood zone near Port Arthur?
It depends, but both are high-risk zones, but only AE has a base flood elevation, which shapes building rules near Beaumont.
What is a base flood elevation for land near Beaumont?
In most cases, the BFE is printed in AE zones on FEMA's map; surveyors near Beaumont use it often.
What is a parcel ID near Bevil Oaks?
It's the number the appraisal district uses to track a tract near Nederland; copy it before you call anyone.
