Ahead of any purchase around San Perlita, pull up the Raymondville flood zone map: FEMA's zone label affects insurance, permits and resale. This Raymondville guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Texas county CAD map.
Getting started with the Raymondville flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Lyford, and choose the dynamic map. Rural land near San Perlita with no street number can still be found: zoom in from the nearest road then click the parcel area.
The free map to start with
Begin with the Texas county CAD map; it includes each tax parcel in the county, San Perlita included. When a rural tract has no street number, zoom in from San Perlita and select the outline. Closer to Lyford, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
Offices that can help
Questions about value or the owner field for land near Lyford go to the appraisal district, the office behind the parcel record. Building or septic questions for a lot near Lyford are for the local planning and health departments, town or county, depending on location.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a tree line near Lyford may sit some distance off the line on screen. For a home near San Perlita, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Where Raymondville fits in
Raymondville lies within Willacy County, Texas, and the county assessor maps its lots. As the county seat, Raymondville hosts the courthouse, handy when you need recorded documents. For a parcel near Lyford, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the city limits toward Lyford usually answers to county rules rather than the town's.
Zones on the Raymondville flood zone map
In and around San Perlita, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. On ground around Lyford, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate on the property near Lyford; an insurance quote early keeps the budget honest.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Lyford, though signal can drop in rural spots. A screenshot of the parcel near San Perlita with its ID is a good backup.
