Want a copy of the Imperial County plat book? It's a printed atlas of landownership, usually by township, useful for farms near El Centro NAF. What this county guide covers: how the atlas is organized, where to find editions, and the free online map that stays current, at least around Niland.
Tracking down an Imperial County plat book
If the land is near Holtville, plat books are commercial atlases, with owner names on each tract, usually township by township.
Getting to the right map
Begin with the Imperial County ArcGIS parcel map; it maps every tax parcel around Bombay Beach and Niland. When a rural tract has no street number, pan along Interstate 8 until the lines appear, then click inside the one you want. For a tract near Holtville, copy the parcel ID before closing the panel; every office in the county will want it.
Editions and availability
Not every county has a current edition, so ask at the courthouse, extension office or a local library near Imperial National Wildlife Refuge.
Reading the legal description
California uses the Public Land Survey System, so rural legal descriptions near Desert Shores cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Cibola National Wildlife Refuge can be irregular. Write down the legal description for the tract near El Centro NAF for any title or survey request.
Places you'll see on the map
El Centro serves as the county seat, where most land records are kept. You'll also find Brawley, Calexico, Calipatria, and Holtville, each with its own cluster of lots. About 179,057 people live in Imperial County (Census estimate, 2023) spread over roughly 4,176 square miles. Landmarks such as Colorado River and Cibola National Wildlife Refuge are easy to spot when you zoom out.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near El Centro NAF, though signal can drop in rural spots. A screenshot of the parcel near El Centro NAF with its ID helps when you meet an owner or agent.
Between editions
The Imperial County ArcGIS parcel map is updated more often than any atlas, including rural land around Holtville.
Backing up the map with records
In and around El Centro NAF, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county sit with the County Recorder. For a parcel near Bombay Beach, bring the document number from the tax record to skip a name search.

Common uses
Farmers, hunters and appraisers near Calipatria use plat books for a big-picture view of who owns what.
Before you lean on the lines
The acreage figure is an assessed number; just a licensed surveyor sets the real lines for a parcel near Cibola National Wildlife Refuge. In and around Cibola National Wildlife Refuge, records update in batches, so a deed recorded last month can take weeks to appear.
Getting answers from the right desk
Deeds, mortgages and recorded plats for land near Westmorland come from the County Recorder, often with an online index. Questions about what you can build around El Centro are for the local planning and health departments, depending on whether the land is inside town limits.
Atlas or legal document
For property near Cibola National Wildlife Refuge, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Recorder is a legal document, while the atlas is a reference.
Neighboring parcel maps
Imperial County borders La Paz County, AZ, Yuma County, AZ, Riverside County, and San Diego County; every one of them runs a separate parcel map. A tract near the line by Brawley may be split across two assessors' files, so open the neighboring map before you assume the acreage. Closer to Bombay Beach, our state page lists every bordering county map for California.
