In a growing city with an aging transportation system, will Seattle voters support a $930 million property tax measure this November to Move Seattle?

Seattle Speaks, a live, televised community forum, will consider the biggest levy in Seattle history — $930 million over nine years. The Move Seattle transportation levy, paid for through a property tax, replaces the existing Bridging the Gap transportation levy that expires at the end of this year.

Seattle Channel host Brian Callanan will lead the discussion, 7 p.m., Tuesday, Sept. 29, at Town Hall Seattle, 1119 Eighth Ave. Seattle Speaks is presented by Seattle CityClub, Seattle Channel and Town Hall Seattle.

Joining the panel discussion in support of the levy proposal are Andrew Glass Hastings, transportation advisor to Seattle Mayor Ed Murray, and Maud Daudon, president and CEO of the Seattle Metropolitan Chamber of Commerce. Speaking against the measure are Eugene Wasserman of the Keep Seattle Affordable opposition campaign and Fremont business owner Suzie Burke.

Some critics say the proposal is a collection of disconnected projects and question where the levy dollars will go. Supporters say levy investments offer more choices to move people and goods around Seattle safely and affordably and will help the city keep pace with growth.

Admission to Seattle Speaks is free, but advance registration is required. Doors open at 6 p.m. with audience instructions at 6:30 p.m. and the live televised program at 7 p.m.

The program will be broadcast live on Seattle Channel cable 21 (HD on Comcast 321 and Wave 721) and online. Join the conversation in person or online, where you can take part in polls and voice your opinion via social media and e-mail. Or take the pre-poll and weigh in before the event!

Seattle Speaks is an Emmy Award-winning series that brings together local leaders, critics, stakeholders and residents to deliberate pivotal moments in our city’s history.
