Weighing a property around Ector? Checking the Bonham flood zone map reveals whether it sits in a FEMA flood zone, and the lookup is free. This Bonham guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Fannin CAD interactive map.
Checking the Bonham flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: search an address around Savoy, and pick the FIRMette or map view. A tract near Bailey without an address can still be found: zoom in from the nearest road then click the parcel area.
The viewer Fannin County publishes
Begin with the Fannin CAD interactive map; it covers each tax parcel in the county, Ravenna included. For property near Bailey, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. Closer to Ravenna, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Ector, so load it before you lose signal. A saved image of the lot near Savoy and its lines keeps working without signal.
Getting your bearings
Bonham is the county seat, where most land records are kept. Other places on the map include Ector, Ravenna, Dodd City, and Savoy, where town lots give way to larger tracts. Around 37,571 people call Fannin County home (Census estimate, 2023) spread over some 891 square miles. Fannin County dates to 1838, so old deeds can run back a long way. Places such as Caddo National Grassland help you orient on the aerial around Windom.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor can set the real lines on land around Savoy. For a parcel near Savoy, owner names and values update on a schedule, so a deed recorded last month may not show yet.
City limits and county records
Bonham lies within Fannin County, Texas, and the county assessor maps its lots. Bonham is also the county seat, so deeds and plats are filed in town. Out toward Ravenna, City or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the town limits out by Ravenna generally follows county rules, not municipal ones.
Zones on the Bonham flood zone map
Near Savoy, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. In and around Windom, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so open the Fannin CAD interactive map next to see exactly which lot near Ector you're looking at.
Low spots and local drainage
Low-lying fields near Windom aren't always studied in detail, so walk the land after rain. Marshy spots near Windom can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Lenders and permits
Around Dodd City, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Building or adding on near Savoy in a mapped zone can trigger elevation rules; check with the county or town building office early.
Who handles what
If the acreage or value on a parcel near Bailey looks off belong with the appraisal district, since that office keeps the assessment data. Building or septic questions for a lot near Ector are for the local planning and health departments, town or county, depending on location.
How land is described here
Older tracts around Savoy commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Town lots near Dodd City are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Ravenna when you talk to a surveyor.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate for the house near Dodd City; an insurance quote early avoids surprises.
