Before an offer near Iola, check the Grimes County flood zone map: the zone on that map shapes insurance, permits and resale. What this Grimes County guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Grimes CAD interactive map.
Where the Grimes County flood zone map lives
With a lot near Iola, the official source is FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Navasota with no street number is still easy to locate: pan from the closest town and click the spot.
The viewer Grimes County publishes
Property in and around Anderson can be looked up on the Grimes CAD interactive map, a viewer that needs no account. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, for land near Todd Mission included. In and around Richards, save the parcel ID while you have it open; every clerk in the county will want it.
Reading A, AE and X
Zone AE carries a published BFE, while plain Zone A does not; builders around Navasota design to it. For acreage around Apolonia, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Sections, lots and bearings
Older tracts around Shiro commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Subdivision lots in Pinebrook usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Todd Mission when you talk to a surveyor.
On site with the map
Most viewers work in a phone browser, useful out on a road near Richards, though signal can drop in rural spots. A saved image of the lot near Anderson and its lines helps when you meet an owner or agent.
Which office to call
Questions about value or the owner field for land near Todd Mission go to the appraisal district, the office behind the parcel record. Building or septic questions for a lot near Bedias need the planning or permitting office, town or county, depending on location.
Questions to ask before you buy
Around Richards, request about past flood claims before closing; getting a quote early avoids surprises.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Grimes CAD interactive map too for the outline of the tract near Richards.
Beyond the mapped zones
Creeks and ditches near Pinebrook aren't always studied in detail, so look for water marks and debris lines. Wetlands near Todd Mission can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Before you lean on the lines
For property near Roans Prairie, the acreage figure is an assessed number; only a licensed surveyor sets the real lines on the ground. For a home near Richards, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Grimes County in a few facts
Anderson serves as the county seat, which is where the courthouse records live. You'll also find Bedias, Iola, Navasota, and Plantersville, where town lots give way to larger tracts. Around 32,384 people live in Grimes County (Census estimate, 2023) across some 787 square miles. The county was organized in 1846, and some chains of title near Iola are long.
Money questions tied to the zone
For land near Todd Mission, ask for an Elevation Certificate: it can change the insurance price a lot. Building or adding on near Iola in a mapped zone usually means extra permit review; call the permitting office early.
When a parcel crosses a boundary
Grimes County touches Brazos County, Madison County, Montgomery County, Walker County, and Waller County, and each of those keeps its own parcel map. Ground near Anderson that runs to the line may show up across two assessors' files, so check the adjacent map as well. Closer to Apolonia, our state page links every neighboring county map across Texas.
Grimes County: common questions
What is the difference between Zone A and AE near Shiro?
Good question; AE is a Special Flood Hazard Area with a published base flood elevation, which shapes building rules near Roans Prairie.

If you're looking near Pinebrook, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground, and lenders accept the result.
Will my lender require flood insurance near Pinebrook?
It depends, but for a building near Richards in an A or V zone with a federally backed or regulated mortgage, it's generally required; elsewhere it's optional.
How do I check the flood zone for an address in Grimes County?
For most people, search the address near Apolonia on FEMA's Flood Map Service Center, and the zone code appears on the map.
Which office handles records for land near Pinebrook?
