Want a copy of the San Patricio County plat book? It's a printed atlas of landownership, usually by township, popular with hunters, farmers and buyers near La Paloma Addition. Covered here for San Patricio County: what's in a plat book, where to look for printed copies, and the free online map that stays current.
Getting started with the San Patricio County plat book
For a home near Corpus Christi, a plat book is a privately published atlas, that map ownership across the countryside, usually township by township.
Pulling up a parcel
Parcels around Edgewater Estates can be looked up on the San Patricio CAD interactive map, a viewer that needs no account. If you only know roughly where the land is, follow US Route 181 on the aerial and click the parcel itself, for land near Del Sol included. For land near Del Sol, copy the parcel ID from that panel; each office in the county asks for it first.
Common uses
Farmers, hunters and appraisers near La Paloma Addition use plat books for a big-picture view of who owns what.
Finding a printed edition
Libraries near La Paloma Addition sometimes keep past atlases, useful for family or title research.
Making your own township pages
Screenshot each section of the viewer around Corpus Christi and keep them in a binder for the truck.
Who handles what
For assessment questions about property around Sinton go to the appraisal district, the office behind the parcel record. Building or septic questions for a lot near Aransas Pass need the planning or permitting office, depending on whether the land is inside town limits.
On site with the map
Most viewers work in a phone browser, useful out on a road near Edroy, but coverage can be spotty out of town. A printout of the tract near Edgewater Estates keeps working without signal.
Using the parcel viewer instead
For current names, use the San Patricio CAD interactive map, across the county, whether the land is near Edroy or elsewhere in the county.
Sections, lots and bearings
Tracts outside towns near Del Sol are often described by metes and bounds, a series of courses and distances from a starting point. Town lots near Del Sol usually use lot and block from a recorded plat instead, making them easier to find. Write down the legal description for the tract near Falman for any title or survey request.
Deeds, plats and who keeps them
For a home near Edroy, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county sit with the County Clerk. Inherited tracts around Edgewater Estates may go back through many deeds, and a title company is worth hiring before a purchase.
When a parcel crosses a boundary
San Patricio County borders Aransas County, Bee County, Jim Wells County, Live Oak County, and Nueces County; every one of them runs a separate parcel map. A tract near the line by Edgewater Estates can show up in two county records, so look at the neighboring map before you assume the acreage. Out toward La Paloma Addition, the Platbookmapper state page links every bordering county map for Texas.
Places you'll see on the map
Sinton holds the county offices, where most land records are kept. You'll also find Aransas Pass, Corpus Christi, Ingleside, and Portland, each with its own cluster of lots. Around 70,660 people call San Patricio County home (Census estimate, 2023) across some 693 square miles. The county dates to 1836, and some chains of title near Corpus Christi are long.
Before you lean on the lines
In and around Edgewater Estates, the acreage figure is an assessed number; just a licensed surveyor establishes the real lines on the ground. Owner names and values update on a schedule, so a fresh transfer around Del Sol may not show yet.
Atlas or legal document
If you're looking near Portland, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Clerk is a legal document, while the atlas is a reference.
