Ahead of any purchase around Palm Valley, pull up the La Feria flood zone map: the zone on that map shapes insurance, permits and resale. In this La Feria guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the appraisal district map.
Checking the La Feria flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: type an address near Primera, and pick the FIRMette or map view. A tract near Combes without an address can still be found: zoom in from Interstate 2 and click the spot.
Getting to the right map
Your first stop is the appraisal district map; it covers each assessed parcel from Palm Valley to Combes. With a lot near Combes, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Palm Valley, a pop-up or side panel typically gives the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Beyond the mapped zones
Small streams around Rangerville aren't always studied in detail, so walk the land after rain. Wet ground around Santa Rosa is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
City limits and county records
La Feria lies within Cameron County, Texas, so its parcels are on the county's map. Around Palm Valley, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits out by Rangerville usually answers to county rules, not municipal ones.
Zones on the La Feria flood zone map
Zone AE carries a published BFE, and an unnumbered A zone has none; that elevation drives building rules near Harlingen. For property near Primera, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
A short flood checklist
Ask the listing agent for any Elevation Certificate on the property near Primera; getting a quote early keeps the budget honest.
A word on accuracy
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near Combes often sits several feet off the line on screen. Near Primera, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the appraisal district map next to see exactly which lot near Santa Rosa you're looking at.
Cameron County in a few facts
Brownsville holds the county offices, home to the main records offices. You'll also find Palm Valley, Rangerville, Primera, and Santa Rosa. About 426,710 people call Cameron County home (Census Bureau estimate, 2023) across roughly 892 square miles. Cameron County dates to 1848, and some chains of title near Harlingen are long. Places such as Laguna Atascosa National Wildlife Refuge help you orient on the aerial around Santa Rosa.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements covering ground around Primera sit with the County Clerk. For a parcel near Combes, have ready the document number shown in the record panel and the lookup takes minutes.
Getting answers from the right desk
For assessment questions about property around Combes are handled by the appraisal district, since that office keeps the assessment data. Building or septic questions for a lot near Harlingen are for the local planning and health departments, town or county, depending on location.
Insurance, lenders and building
For a structure inside an A or V zone and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, and that holds around Rangerville too. New construction in a floodplain near Combes often needs a floodplain permit; ask the local floodplain administrator early.
Land on the county line
Cameron County meets Hidalgo County and Willacy County, all with their own assessor records. A tract near the line by Santa Rosa may show up in two county records, so look at the adjacent map too. Closer to Santa Rosa, the Platbookmapper state page links every neighboring county map for Texas.

Do I need to worry about flooding in Zone X around Santa Rosa?
Generally, Zone X near Harlingen means moderate (shaded) or minimal (unshaded) mapped risk; many owners near Combes buy coverage anyway.
Does the county parcel map show flood zones near Palm Valley?
Good question; a flood layer may appear in the appraisal district map layer list, but FEMA's own map is the official source.
Is my property near Rangerville in a flood zone?
Short answer: look up the spot near Combes in FEMA's National Flood Hazard Layer viewer, which takes a couple of minutes.
When is flood insurance required near Combes?
It depends, but lenders generally require it for buildings near Palm Valley in a Special Flood Hazard Area when the loan is federally regulated or insured; outside those zones it's your call.
