Trying to understand lot lines near Point Comfort? What you want is the Port Lavaca plat map, because the recorded plat shows how the land was divided. Covered here for Port Lavaca: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Port Lavaca plat map
For a subdivision near Point Comfort, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
The viewer Calhoun County publishes
Begin with the appraisal district interactive map; it maps each tax parcel from Point Comfort to Seadrift. Closer to Seadrift, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Closer to Seadrift, the parcel card normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Sections, lots and bearings
Older tracts around Seadrift are often described by metes and bounds, a series of courses and distances from a starting point. Subdivision lots in Point Comfort are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Point Comfort for any title or survey request.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Point Comfort, but coverage can be spotty out of town. A screenshot of the parcel near Seadrift with its ID keeps working without signal.
Port Lavaca and the county around it
Port Lavaca sits in Calhoun County, Texas, so its parcels are on the county's map. Port Lavaca is also the county seat, so deeds and plats are filed in town. For acreage around Seadrift, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records.

Offices that can help
Questions about value or the owner field for land near Point Comfort are handled by the appraisal district, since that office keeps the assessment data. Questions about what you can build around Seadrift go to planning, building or health offices, town or county, depending on location.
How a plat differs from the tax map
If the tax map and plat differ near Point Comfort, trust the recorded documents over the GIS layer.
A word on accuracy
Acreage on the record is a tax-roll number; just a licensed surveyor sets the real corners for a parcel near Point Comfort. On ground around Seadrift, owner names and values update on a schedule, so a deed recorded last month might lag behind.
When a plat changes
An amended plat may change lots around Seadrift, so check for later filings; street vacations show up in the records too.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, plats and easements covering ground around Point Comfort are kept by the County Clerk. Inherited tracts around Point Comfort may trace back through many deeds, and a title company is worth hiring before a purchase.
Metes and bounds instead
Rural land near Point Comfort that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land there.
Lots, blocks and easements
Recorded easements around Point Comfort can block a shed or pool; check the plat notes and any covenants.
