AUSTIN — For three open Austin City Council seats, it was too close to call in the Nov. 6 Election. Now, voters will decide who will fill districts: 1, 3 and 8.

Early voting in the runoff elections ran from Nov. 29 to Dec. 7 before the run-off election on Dec. 11. You can learn more about polling locations, hours of operations and other races on the Travis County and Hays County websites.

Here's an explainer about each race:

District 1

Candidates Natasha Harper Madison and Mariana Salazar were in a tight race Election night, with Salazar receiving 26 percent of the votes and Harper-Madison receiving 25 percent -- a difference of a little more than 200 votes. The two were clearly the front-runners in a race that initially included four other candidates.
