In the race for the Austin City Council District 6 seat, Donald S. Zimmerman leads Jimmy Flannigan with 2,478 votes, or 52.11 percent of the votes, to Flannigan's 2,277 votes, or 47.89 percent, according to early runoff voting totals.

Flannigan, a longtime small-business owner, said fighting traffic, affordability, public safety, sustainable growth and a streamlined city government would be his top priorities if elected. He received 3,697 votes, or 24.05 percent of votes, in the Nov. 4 election.

A fifth-generation Texan, Zimmerman founded the Travis County Taxpayers Union in 2012. He said ending corporate favoritism, enacting the maximum allowable homestead exemption and solving transportation issues through roads in place of rail are his top priorities. Zimmerman received 3,722 votes, or 24.21 percent of the vote, the most of any District 6 candidate in the Nov. 4 election.

The Dec. 16 runoff is being held because no District 6 candidate garnered at least 50 percent of the vote in the Nov. 4 election. Since Flannigan and Zimmerman were the top two vote-getters Nov. 4, they proceeded to the runoff.

In November 2013, a 14-member Independent Citizens Redistricting Commission established the boundaries of the city's 10 new voting districts. Starting with the November 2014 elections and December runoffs, one City Council member is elected from each geographic area, and the mayor is elected at-large.

Austin City Council District 6 covers about 48 square miles of the northwest and western portions of Austin. The area primarily surrounds RR 620 and includes the entire Williamson County portion of the city.

Neighborhoods in District 6 include Anderson Mill, Angus Valley, Avery Ranch, Balcones Village, Canyon Creek, Los Indios, Milwood, Riata and River Place. It is the only district in the city that has a majority of Republican voters.

After the new City Council is elected, five members will be selected at random to serve initial two-year terms, and five will serve initial four-year terms. The initial terms allow future council elections to be held every two years, and future council terms will last four years.

All results are unofficial until canvassed.
