Buying a lot in a subdivision near Bonney? What you want is the Iowa Colony plat map, since it shows lots, streets and easements as approved. Covered here for Iowa Colony: where to request a copy, plat versus tax map, and the details that matter to buyers.
Getting started with the Iowa Colony plat map
For a lot in Iowa Colony, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Pulling up a parcel
Begin with the Brazoria County parcel viewer; it maps every assessed parcel in the county, Alvin included. When a rural tract has no street number, pan along the nearest road and click the parcel itself, and that holds around Bonney too. For land near Brookside Village, write down the parcel ID while you have it open; every clerk in the county asks for it first.
How land is described here
Older tracts around Bonney are often described by metes and bounds, which trace the boundary call by call. Town lots near Bonney refer to a recorded plat, which is simpler to follow. Write down the legal description for the tract near Bonney for any title or survey request.
Getting answers from the right desk

Plat map vs. parcel map
If the tax map and plat differ near Brookside Village, trust the recorded documents over the GIS layer.
Lots, blocks and easements
In and around Brookside Village, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Limits of the parcel data
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Sandy Point often sits a few yards off the line on screen. Out toward Sandy Point, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Ordering the Iowa Colony plat map
For a tract near Manvel, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
When a parcel crosses a boundary
Brazoria County touches Fort Bend County, Galveston County, Harris County, Matagorda County, and Wharton County, and each of those keeps its own parcel map. A tract near the line by Sandy Point can show up in two county records, so open the adjacent map before you assume the acreage. With a lot near Manvel, the Platbookmapper state page links each bordering county map for Texas.
Land outside a subdivision
Acreage around Pearland outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
When a plat changes
Lots near Brookside Village can be combined or reconfigured by a replat, so check for later filings; street vacations show up in the records too.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements for land near Bonney are kept by the County Clerk. Long-held tracts around Bonney can go back through a long string of deeds, so a title company earns its fee on a real sale.
