When a deed near Anita says lot and block, look up the Atlantic plat map it refers to. This Atlantic guide covers: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
Who keeps the Atlantic plat map
For land around Marne, look for the plat book reference on the parcel record; use it to request a copy.
The free map to start with
Go first to the Cass County Beacon site; it includes each assessed parcel around Lewis and Wiota. When a rural tract has no street number, pan along the nearest road and click the parcel itself, whether the land is near Marne or elsewhere in the county. For a parcel near Anita, the parcel card usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Atlantic and the county around it
Atlantic lies within Cass County, Iowa, and the county assessor maps its lots. As the county seat, Atlantic hosts the courthouse, handy when you need recorded documents. Closer to Cumberland, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits out by Marne often falls under county rules instead.
Cass County in a few facts
Atlantic is the county seat, which is where the courthouse records live. You'll also find Marne, Lewis, Wiota, and Cumberland, where town lots give way to larger tracts. About 13,130 people live in Cass County (Census estimate, 2023) across about 564 square miles. Cass County was formed in 1851, and some chains of title near Wiota are long.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Wiota, though signal can drop in rural spots. A screenshot of the parcel near Marne with its ID is a good backup.
Neighboring parcel maps
Cass County meets Adair County, Adams County, Audubon County, Guthrie County, and Montgomery County, and each of those keeps its own parcel map. A tract near the line by Griswold may be split in two county records, so open the neighboring map as well. For a parcel near Anita, our state page lists every bordering county map for Iowa.
Recorded documents worth pulling
The map is an index, not the title: deeds, plats and easements covering ground around Wiota are kept by the County Recorder. Long-held tracts near Anita may sit on several deeds, so a title company is worth hiring before a purchase.
Sections, lots and bearings
Iowa follows the Public Land Survey System, which means a tract near Griswold is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Wiota can be irregular. Keep the legal description for land near Marne before you request a deed or survey.
Two different maps
The tax map on the Cass County Beacon site is a summary, whereas the plat carries surveyed dimensions.
Replats and vacations
Lots near Cumberland can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Lewis show up in the records too.
What the map can't tell you
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near Cumberland can sit several feet off the line on screen. For property near Wiota, records update in batches, so a deed recorded last month might lag behind.
Metes and bounds instead
Rural land near Cumberland that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Which office to call
Anything recorded against property around Anita sit in the index kept by the County Recorder, sometimes only in person. Zoning, permits and septic questions near Wiota go to planning, building or health offices, depending on whether the land is inside town limits.
Details on the Atlantic plat map

Online indexes and office visits
