Development Patterns

The portion of this subwatershed generally north of Burnside includes some of Portland’s oldest neighborhoods. The blocks just west of the Willamette were early residential and commercial areas serving the docks along the river. Wetlands north of Everett were part of the floodplain that included Couch Lake and were filled in the late 1800s to accommodate growth.

The areas farther west were early residential neighborhoods, and the portion of the subwatershed along the canyon now occupied by Highway 26 was developed in the early 1900s.

The entire subwatershed has redeveloped into a dense urban area. Commercial development dominates the areas in the eastern portions, with an increasing incidence of multiple story apartments and condominiums west of NW Broadway. The areas generally south of Highway 26 are primarily single family residential neighborhoods.

New development, including commercial and residential, has occurred on the former industrial area generally north of NW Flanders and east of Interstate 405.

Major transportation corridors include Interstate 405, West Burnside Street, Naito Parkway, and Highway 26, which effectively splits the subwatershed into north and south halves.
