Kenmore also hosts one of the last industrial ports on Lake Washington, at the mouth of the Sammamish River. Larger local businesses near the port include Rinker Materials's Kenmore plant, Kenmore Ready-Mix (cements and asphalts, a division of Glacier Northwest), Pacific Topsoils (topsoils and landscape construction materials), Michael Homchick Stoneworks (stone fabrication and installation), Plywood Supply (lumber, plywood, and millwork, wholesale, retail, and company headquarters), and several others. As home to the James G. Murphy Company, one of the ten largest commercial/industrial auction houses in the United States, the city is also an auction center.
