If a legal description for land in Portland cites a lot number, you'll need the Portland plat map to make sense of it. In this Portland guide: where to request a copy, how a plat differs from a parcel map, and the details that matter to buyers.
Who keeps the Portland plat map
For land around White House, the deed usually cites the plat; bring that to the recorder's office or its online index.
Getting to the right map
Begin with the Tennessee Property Viewer; it includes every tax parcel from Orlinda to White House. Closer to Greenbrier, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Cross Plains, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Orlinda, but coverage can be spotty out of town. A printout of the tract near Orlinda helps when you meet an owner or agent.
Land on the county line
Robertson County borders Logan County, KY, Simpson County, KY, Todd County, KY, Cheatham County, and Davidson County, and each of those keeps its own parcel map. A tract near the line by Greenbrier may show up in two county records, so check the neighboring map before you assume the acreage. Closer to Millersville, the Platbookmapper state page links each neighboring county map for Tennessee.
Where Portland fits in
Portland is part of Robertson County, Tennessee, which means parcel data comes from the county. Out toward Ridgetop, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits near Ridgetop generally falls under county rules, not municipal ones.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements covering ground around Orlinda sit with the Register of Deeds. If the land is near White House, have ready the document number listed on the parcel record so staff can find the deed fast.
When a plat changes
An amended plat may change lots around Cross Plains, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
What the map can't tell you
Listed acreage is an estimate; just a licensed surveyor can set the real lines on land around Cross Plains. In and around Cross Plains, records update in batches, so a deed recorded last month might lag behind.
How land is described here
Tracts outside towns near Greenbrier commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in Cross Plains are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Cross Plains when you talk to a surveyor.
Metes and bounds instead
Rural land near Greenbrier that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Recorded plat or GIS layer
When the two disagree for a lot near Cross Plains, go with the plat and a surveyor's work.
Details on the Portland plat map
Utility or drainage strips on a lot in Portland stay with the land when it sells; check the plat notes and any covenants.
