When a deed near Forsan says lot and block, the Big Spring plat map is where those numbers come from. What this Big Spring guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Tracking down the Big Spring plat map
For a lot in Big Spring, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Getting to the right map
The official parcel map for this area is the Howard CAD interactive map, and anyone can open it without signing up. Around Coahoma, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Forsan, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
City limits and county records
Big Spring lies within Howard County, Texas, and the county assessor maps its lots. As the county seat, Big Spring hosts the courthouse, handy when you need recorded documents. Around Coahoma, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits near Coahoma often falls under county rules, not municipal ones.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Forsan, though signal can drop in rural spots. A saved image of the lot near Forsan and its lines keeps working without signal.
Recorded plat or GIS layer
The tax map on the Howard CAD interactive map is a summary, while the recorded plat is the legal document.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Forsan are filed with the County Clerk. Older tracts near Forsan may go back through several deeds, so a title company can sort it out before a purchase.
When there's no plat
Rural land near Forsan that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Reading the legal description
Tracts outside towns near Forsan are often described by metes and bounds, a series of courses and distances from a starting point. Subdivision lots in Forsan are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Coahoma before you request a deed or survey.
Which office to call
For assessment questions about property around Coahoma go to the appraisal district, which maintains the tax roll. Questions about what you can build around Coahoma need the planning or permitting office, depending on whether the land is inside town limits.

Details on the Big Spring plat map
Utility or drainage strips on a lot in Big Spring limit where you can build or fence; check the plat notes and any covenants.
What the map can't tell you
The acreage figure is an estimate; just a licensed surveyor can set the real corners on land around Forsan. If the land is near Forsan, records update in batches, so a deed recorded last month can take weeks to appear.
Getting a copy
In and around Forsan, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
When a plat changes
