Brazoria County Sheriff | Where the plate reads go
In one motion in August 2026 the Commissioners Court put Brazoria County's plate reads into a statewide database and a federal drug program's regional one. Both are shared with agencies the county does not name.
At a glance
- What the Court approved
- 11 August 2026, items H.7 and H.8, both inside the consent block: the Houston High Intensity Drug Trafficking Area plate reader memoranda under the District Attorney, and the Texas Department of Public Safety plate reader memoranda under the Sheriff's Office [4]
- What goes into the state database
- For each read: the plate number, the latitude and longitude where it was captured, the date and time, and the identifier of the agency that captured it [1]
- Who else can see it
- A user agency agrees to let the Department of Public Safety share its contributed data with other authorized criminal justice or law enforcement agencies. The agreement names no list [1]
- How long the state keeps a read
- At least one year. The agreement sets a minimum, not a maximum, and says an agency may ask for a shorter period [1]
- How long the regional center keeps a read
- Up to two years where the member agency's state law sets no period, after which the data is purged unless it has become evidence [3]
- Whether searches are audited
- The regional agreement requires an audit log of user access to shared data, kept at least twelve months. The state agreement gives the Department of Public Safety a right to inspect and audit the county, and requires the county to keep records of use and dissemination [1] [3]
- When the county first agreed to export plate information to the state
- Not established, but no later than October 2020: the Court's agenda for 27 October 2020 carries an item authorizing county law enforcement to enter an agreement with the Department of Public Safety for exporting license plate information [2]
- Whether the county has an opt-out or a sharing policy of its own
- None appears in the Commissioners Court record we read [5]
How it happened
- Decision
The first export agreement
Item 7.B.6 on the Commissioners Court's agenda reads "Authorization for Brazoria County Law Enforcement to Enter Into Agreement with DPS for Exporting of License Plate Information". The archive publishes no minutes for that meeting, so the outcome is not established. [2]
- Decision
Two databases, one motion
Items H.7 and H.8 passed inside the consent block, moved by Commissioner Stacy L. Adams and seconded by Commissioner David R. Linder. H.7 is the Houston High Intensity Drug Trafficking Area plate reader memorandum, brought by the District Attorney. H.8 is the pair of Texas Department of Public Safety plate reader memoranda, brought by the Sheriff's Office: a user agreement for the state database and a hotlist agreement for stolen plate and stolen vehicle files. [4] [1] [3]
One motion, two databases
On 11 August 2026 the Brazoria County Commissioners Court approved its consent agenda. Inside it were items H.7 and H.8. H.7 came from the District Attorney and H.8 from the Sheriff’s Office, and between them they connect the county’s plate readers to two shared databases.[4]
The state database
The Department of Public Safety agreement describes the Texas Automated License Plate Reader Database as “shared data from all participating local, state, and federal agencies, as well as TXDPS captured data”. For each read it holds the plate number, the latitude and longitude of the capture, the date and time, and the identifier of the agency that captured it.[1]
Two terms are worth reading closely. The first is about sharing. A participating agency “shall allow TXDPS to share the User Agency’s data contributed to the LPR Database with other authorized criminal justice or law enforcement agencies”.[1] The agreement names none of them.
The second is about time. The agreement sets a minimum retention period of one year for information in the database, “unless the User Agency indicates to TXDPS that a shorter retention period is required”.[1] That is a floor. The agreement sets no ceiling.
The second document under the same item is a hotlist agreement: the Department of Public Safety exports a file of stolen plate and stolen vehicle records from the Texas Crime Information Center, updated hourly, for the county’s readers to match against.[1]
The regional one
The Houston High Intensity Drug Trafficking Area is a multi-jurisdictional program run by an executive board of twenty area law enforcement leaders, half federal and half state and local. Its memorandum covers more than plates. Member agencies agree to share information from “Records Management Systems, Computer Aided Dispatch Systems, Automated License Plate Readers, Intelligence Management Systems, Jail Management Systems, and Law Enforcement Data Sharing Systems”.[3]
Plate data travels to the program’s operations center by fiber or encrypted private network and is kept for the period the member agency’s state law requires. Where state law sets none, the memorandum stores it “for a period not to exceed two years”, after which it is purged unless it has become evidence. Access to shared data is logged, and the log is kept at least twelve months.[3]
This is not new, and the county’s own rules are not written down
The Court’s agenda for 27 October 2020 already carried an item authorizing county law enforcement to enter an agreement with the Department of Public Safety for exporting license plate information.[2] The archive publishes no minutes for that meeting, so what the Court did with it is not established. Six years later the same subject came back as two memoranda inside a consent block.
What the county’s record does not contain is a Brazoria County rule. No policy sets how long the Sheriff’s Office keeps a read on its own system, which agencies may query it, or who checks. The retention periods and audit terms on this page belong to the state and to a federal drug program, and they govern the copies, not the original.
What a resident can ask for
The Sheriff’s Office and the District Attorney each hold the executed copies of these memoranda and the county’s own query logs, if any exist. The Sheriff’s plate readers has the cameras that feed them.
What we do not know
- Which agencies have actually queried Brazoria County's reads, and how often.
- Whether the county keeps its own log of who searched what.
- What the 2020 agreement with the Department of Public Safety said, and whether it is still in force.
