Multnomah County has jurisdiction over about a quarter of the subwatershed, areas located west of Cornell Road. Lands zoned Residential Farm/Forest (RF) are located primarily along the western edge of the subwatershed. A mixture of residential, employment, and commercial designations comprise smaller portions of the subwatershed.
