According to unofficial results, District 10 candidates Mandy Dealey, with 30.65 percent, or 8,539 votes, and Sheri Gallo, with 22.93 percent, or 6,386 votes, will face each other in a runoff election.

"I was not really surprised [to be in the lead] but certainly gratified," Dealey said. "The challenge [of the runoff] will be to highlight the difference between my opponent and myself. I will probably draw attention to my experience and understanding of the issues."

She said the top three issues facing the city are affordability, traffic and transportation, and water.

All results are unofficial until canvassed.

According to early voting results Mandy Dealey is leading the race with 31.73 percent of the votes, or 5,233 votes, to become councilwoman of Austin City Council District 10, which includes the neighborhoods of Great Hills, Jester Estates, Northwest Hills, Rosedale, Spicewood and Tarrytown. Dealey ran on a platform with top issues of water conservation, affordability and transportation.

Margie Burciaga, who ran on a platform of affordability, utility relief, transportation and public safety, has garnered 4.33 percent, or 715 votes.

Tina Cannon, whose platform included property tax appraisals, drought relief, emergency preparedness, affordability and traffic, has received 3.77 percent, or 621 votes.

Candidate Sheri Gallo, whose concerns included city spending, core services, traffic, mobility and affordability, has received 21.92 percent, or 3,615 votes.

Candidate Matt Lamon, who cited his top issues as transportation, living costs, public safety and district representation, has received 3.05 percent, or 503 votes.

Candidate Jason Meeker, whose platform included transportation, wildfire prevention and protecting the Lions Municipal Golf Course, has received 6.01 percent, or 992 votes.

Candidate Robert Thomas ran on a platform of transportation, affordability, education and water and has received 20.2 percent, or 3,331 votes.

Candidate Bill Worsham, with the top issues of mobility, utilities, quality of life, city services and property taxes, has received 9 percent, or 1,484 votes.

This election is the first time in the city's history that voters will choose City Council members from 10 geographic districts—voters can only vote for candidates from their district. The mayor will still be elected at-large, meaning anyone can vote for the mayor.

The candidate who receives more than 50 percent of the votes will win the election. Otherwise the race will proceed to a Dec. 16 runoff election between the two leading candidates.

After the new City Council is established, five council members will be randomly selected 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. Future council terms will last four years.
