Boeing Creek - Course

Course

Boeing Creek's original headwaters have been placed into underground pipes. The creek's main stem emerges from storm drain culverts at the intersection of Greenwood Ave and Carlyle Hall Road, which is considered its source, 47°45′02″N 122°21′27″W / 47.750653°N 122.357629°W / 47.750653; -122.357629 (Boeing Creek source). The creek flows along the Shoreline Community College campus, through Boeing Creek Park (the northern part of Shoreview Park). At the west end of the park the creek empties into Hidden Lake, 47°45′05″N 122°22′16″W / 47.7514864°N 122.3712408°W / 47.7514864; -122.3712408. Boeing Creek exits Hidden Lake through a culvert under Innis Arden Way and flows west through a ravine and under BNSF's railroad tracks before emptying into Puget Sound.

There are two main tributary forks of Boeing Creek. The northern fork emerges from a culvert in Boeing Creek Park. Its water comes from drainage pipes beneath 6th Avenue. This fork joins the main stem in Boeing Creek Park. Another tributary fork rises in the neighborhoods of Shoreview Hills and The Highlands and flows north to join Boeing Creek below Hidden Lake.

The lowermost portion of Boeing Creek flows between the neighborhoods of The Highlands and Innis Arden. The Highlands is an exclusive gated community designed by the Olmsted Brothers in 1909. This portion of the creek is not accessible to the public.

During high flow events, additional water from pipes beneath 175th Street enters Boeing Creek Park, flowing into a stormwater detention basin, then into the northern fork of Boeing Creek.
