- Lake City is the northeast region of Seattle, centered along Lake City Way NE (SR-522), 7–8 miles (11–13 km) northeast of Downtown Seattle. A broader definition of the Lake City area includes all the land between 15th Avenue NE and Lake Washington, and between NE 95th and 98th streets to the Seattle city limits at NE 145th Street. Lake City encompasses much of the Thornton Creek watershed, the focus of a long restoration campaign by citizens and Seattle Public Utilities staff to enhance the residential environment of Lake City.
