When a deed near Retreat says lot and block, look up the Corsicana plat map it refers to. Covered here for Corsicana: where to request a copy, plat versus tax map, and what to look for on the sheet.
Getting started with the Corsicana plat map
For a lot in Corsicana, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
The viewer Navarro County publishes
Your first stop is the Navarro County parcel viewer; it covers each assessed parcel from Angus to Navarro. When a rural tract has no street number, zoom in from Mustang and select the outline. For a tract near Retreat, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
When a plat changes
An amended plat may change lots around Navarro, so check for later filings; vacated streets or alleys also get recorded.
Getting answers from the right desk
If the acreage or value on a parcel near Emhouse looks off go to the appraisal district, since that office keeps the assessment data. Building or septic questions for a lot near Retreat are for the local planning and health departments, town or county, depending on location.
Corsicana and the county around it
Corsicana sits in Navarro County, Texas, so its parcels are on the county's map. Corsicana is also the county seat, which puts the County Clerk close by. For land near Emhouse, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits out by Navarro often answers to county rules instead.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Navarro, but coverage can be spotty out of town. A saved image of the lot near Emhouse and its lines is a good backup.
Recorded plat or GIS layer
If the tax map and plat differ near Retreat, go with the plat and a surveyor's work.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a fence near Navarro can sit a few yards off the line on screen. For a tract near Retreat, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Details on the Corsicana plat map
Recorded easements around Oak Valley limit where you can build or fence; check the plat notes and any covenants.
Backing up the map with records
When the details count, get the recorded deed from the County Clerk; the parcel map near Mustang only summarizes it. For property near Retreat, have ready the instrument number shown in the record panel so staff can find the deed fast.
Metes and bounds instead
Acreage around Oak Valley outside a subdivision may have no plat at all; look for a recorded survey for land near Angus.

Legal descriptions in Texas
Tracts outside towns near Mustang are often described by metes and bounds, a series of courses and distances from a starting point. Platted lots around Angus are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Navarro before you request a deed or survey.

Acreage along the edge near Angus can show up across two assessors' files, so open the neighboring map as well.

Getting a copy

Questions about the Corsicana plat map

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
