Before an offer near Gulfport, pull up the Long Beach flood zone map: the zone on that map shapes insurance, building rules and resale. This Long Beach guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the county parcel viewer for land near Gulfport.
Where the Long Beach flood zone map lives
The official source is FEMA's Flood Map Service Center: type an address near D'Iberville, and choose the dynamic map. Vacant ground around Biloxi is still easy to locate: zoom in from US Route 90 and click inside the land.
Opening the official parcel viewer
Go first to the Harrison County parcel viewer; it includes each assessed parcel around Biloxi and Pass Christian. For a parcel near D'Iberville, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Biloxi, the record panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
City limits and county records
Long Beach lies within Harrison County, Mississippi, which means parcel data comes from the county. Out toward Pass Christian, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits near D'Iberville generally answers to county rules, not municipal ones.
What the zone letters mean
An AE label carries a published BFE, while plain Zone A does not; builders around Pass Christian design to it. Around D'Iberville, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
What to request from a seller
Request for any Elevation Certificate on the property near Pass Christian; getting a quote early keeps the budget honest.
Low spots and local drainage
Low-lying fields near Biloxi may not have detailed mapping, so walk the land after rain. Wet ground around Pass Christian is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Biloxi, so load it before you lose signal. A printout of the tract near Gulfport is a good backup.
Which office to call
Questions about value or the owner field for land near D'Iberville are handled by the County Tax Assessor, the office behind the parcel record. Building or septic questions for a lot near D'Iberville are for the local planning and health departments, depending on whether the land is inside town limits.
Next door to Harrison County
Harrison County borders St. Bernard Parish, LA, Hancock County, Jackson County, Pearl River County, and Stone County; every one of them runs a separate parcel map. Acreage along the edge near Biloxi may show up across two assessors' files, so check the adjacent map too. For property near Gulfport, the Platbookmapper state page links each neighboring county map across Mississippi.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so pair it with the Harrison County parcel viewer for the outline of the tract near Gulfport.
Sections, lots and bearings
Mississippi is laid out under the Public Land Survey System, so deeds around Gulfport reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Biloxi can be irregular. Write down the legal description for the tract near Biloxi when you talk to a surveyor.
Harrison County in a few facts
Biloxi holds the county offices, where most land records are kept. You'll also find Pass Christian, Gulfport, and D'Iberville, where town lots give way to larger tracts. Roughly 210,612 people live in Harrison County (Census Bureau estimate, 2023) spread over about 574 square miles. Harrison County was organized in 1841, which matters when you trace an old farm's title. Features like Tchoutacabouffa River, Biloxi Bay, and De Soto National Forest help you orient on the aerial around Biloxi.
What the map can't tell you
Listed acreage is a tax-roll number; just a licensed surveyor establishes the real corners for a parcel near D'Iberville. Around Pass Christian, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Insurance, lenders and building
Closer to Gulfport, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Gulfport can trigger elevation rules; ask the local floodplain administrator before you plan.
