After clicking on the content menu, you will see precinct options. Click on the precinct category that you want to view. In this case, we're going to choose the Brazos County Commissioners Court Precincts.
After you've selected the precinct category that you want to view, use the search bar in the top-right of the site to search your address. When you submit the search (by pressing ENTER or clicking the magnifying glass), the map will zoom in on your address and you will be able to see which precinct you are in.
