Zero emission buses are the future of transit, and Metro is moving forward with a large and important first step

Emissions from transportation make up a significant portion of carbon pollution. Electric vehicles offer solutions that more public agencies including our client, King County Metro Transit (Washington State), are turning to for reducing carbon emissions. With a goal to achieve a zero-emission bus (ZEB) fleet by 2035, King County Metro contracted us for engineering and design services for its Interim Base Electrification (IBE) project.

The $67 million IBE project will provide parking and charging stations for 120 ZEB buses at the existing King County Interim South Base. Our role includes providing electrical engineering services, transportation planning, information and communications technology design, acoustic design, charging system design, and even archaeological services should they be required.

King County Metro, which serves a population of more than 2.1 million people, is leading the transit industry as an early adopter of battery-electric buses that produce no emissions. Electrification also has the potential for lower operating costs. System users will find the electric buses are quieter on-board, as well as in the community. Metro’s goal is to maintain its current fleet of approximately 1,400 coaches as it transitions to a ZEB fleet by 2035 in alignment with the County’s equity and social justice goals.
