Seattle is one of the fastest growing cities in the nation, and South Lake Union and Denny Triangle are among its fastest growing neighborhoods. To meet the accelerating power needs of current and anticipated consumers, City Light decided to construct a new electrical substation. The substation, the first and largest of its kind in 30 years, includes an underground distribution network and transmission line. Prior to construction, the utility conducted a two-year design process that included numerous public meetings, close engagement with stakeholders, and dozens of briefings to neighborhood groups and organizations. This extensive community involvement effort resulted in a one-of-a-kind substation design that meets the needs of the utility, while bringing significant amenities to the neighborhood. Feedback from the community was incorporated in the design of the community spaces, off-leash area, and public art. The new substation will support the city's rapid growth, help fuel the local economy, and provide the community a place to utilize and enjoy for years to come.
