A majority of voters — 56 percent to 44 percent — were approving Proposition 1, the bond measure that would pay for a new Mountlake Terrace Civic Center, according to primary election results released Tuesday night. However, the measure’s future is uncertain since it requires a 60-percent yes vote to pass.

Returns issued through the Snohomish County Elections office shortly after 8 p.m. showed that out of 1,872 ballots returned, the measure received 1,050 yes votes to 822 against. The next update reflecting additional ballots received will be released at 5 p.m. Wednesday.

“We’re still cautiously optimistic that we’ll get enough votes to put us over the top,” said Bonnie Mercer, chair of the Yes on Proposition 1 campaign. Mercer expressed “appreciation for all of the volunteers who have worked so hard” to pass the measure.

Approval of Proposition 1 would authorize the city to raise $25 million through the sale of municipal bonds to build a new city hall, build a new community/senior center, remodel and enlarge the current police station, upgrade furnishings and the roof of the library building, and construct outdoor campus space on the southwest corner of 232nd Street Southwest and 58th Avenue West. Repayment of the 30-year bonds would be through an increase in Mountlake Terrace property taxes beginning in 2014.

Here are the other primary election results for MLT voters. In all races, the top two vote-getters, regardless of political party, advance to the November general election.
