Run-off elections will be held next month to determine mayor races in both Waterloo and Cedar Falls.

Voters in each city must return to the polls on Dec. 1, 2015, because none of the candidates in Tuesday's municipal elections failed to garner the required 50-percent support needed to win the races.

In Waterloo, the run-off election will feature Ward 4 city councilman Quenton Hart and former Mayor Tim Hurley. Hart was the top vote-getter in Tuesday's election, picking up 34-percent of the votes. Hurley was favored on 26-percent of the ballots cast and finished second among the five candidates in the race.

Hurley previously served three terms as Waterloo mayor from 2004 to 2009, and was involved in the city's first-ever run-off election when he was first elected to office in November 2003. Hart is hoping to become Waterloo's first black mayor.

The winner of the Dec. 1 run-off election will replace out-going Waterloo Mayor Buck Clark, who chose not to run for a fourth term.

The Waterloo mayor's race also featured Leah Morrison, who finished third behind Hart and Hurley with 24 percent of the votes. Black Hawk County Supervisor and former Waterloo Fire Chief Frank Magsamen ended up in fourth place (15.2 percent), finishing ahead of Wayne Natham (one percent).

The run-off race for Cedar Falls mayor will feature school board member Jim Brown and incumbant city leader Jon Crews, the top vote-getters among three candidates in Tuesday's election. Brown got 45-percent of the votes cast, while Crews got by 35-percent. The third candidate, David Halterman, finished with 20-percent support.

City Council Races - Waterloo & Cedar Falls

The mayor's race in Waterloo won't be only one decided next month. One city council seat will also be up for grabs.

Jerome Amos Jr. and Chris Schwartz are both hoping to replace Hart as the Ward 4 city council representative and vying to get the most votes in the Dec. 1 run-off election. Amos garnered 33.4-percent of the vote on Tuesday, while Schwartz finished with nearly 30-percent support. They were the top two vote-getters in the four-way race, which also featured Agnes Kress (19 percent) and Rosetta Robinson (17.6 percent).

The other contested city council race in Waterloo was won by Bruce Jacobs in a landslide. The commercial banker picked up more than 72 percent of the votes cast in the Ward 2 race and out-distanced his lone challenger, Robbie Hadaway.

In Cedar Falls, unofficial election results show challenger Tom Blanford defeated incumbent Jim Stichter by just 32 votes (473 to 441), while At-large incumbent Dave Wieland won re-election over Tyler Trunnell by just 83 votes. Incumbent Susan de Buhr coasted by challenger Kyle Helland with 62 percent of the vote.

Grout Museum District Levy - Waterloo

A separate issue on the ballot in Waterloo was overwhelmingly approved by voters on Tuesday. A property tax levy to support annual operations of the local Grout Museum District passed by a wide margin, with 59-percent of the voters (5,559) saying "Yes" and 41-percent (3,937) casting ballots against the measure.

Waterloo's Grout Museum District includes the Grout Museum of History and Science, the Sullivan Brothers Iowa Veterans Museum, the Bluedorn Science Imaginarium, the Snowden House, and the Renssellaer Russell House Museum.
