About Precinct Splits
A precinct split is a geographic subdivision of a precinct. Within a precinct split, all voters are eligible to vote in exactly the same combination of districts. A precinct split is typically necessary when there are changes to districts within a precinct, such as the incorporation of county land within a city or creation of a new taxing district.
In the illustration below, a precinct split was created to accommodate voters in the precinct affected by a city incorporation that makes them eligible to vote in city elections.
In your county's Voter Focus database, each precinct split has a record where the districts for the precinct split are defined. Precinct split records are maintained in STREETS &PRECINCTS > Precinct Maintenance, within the record of the parent precinct. Each precinct split has an ID consisting of the parent precinct ID plus a precinct split ID. The exact format of the ID depends on the system settings for your county. See About Precinct IDs for more information.
