As elected officials, we are committed to serving the public good. That requires us not only to think beyond what’s needed for our communities to thrive today but also to focus on long-term planning for current and future residents. That is why we both support the Port of Seattle’s proposed second terminal at Seattle-Tacoma International Airport. The growth of our region over the last few decades — more jobs, more people, more economic activity — has been a net positive to our region.
