About the company
Hanson Tree Service LLC, doing business as Hanson LLC, operates as a woman-owned small disadvantaged business providing landscaping and tree service to federal agencies as a prime contractor under Total Small Business set-asides. Based in Auburn, Washington, Hanson is a for-profit limited liability company certified as a self-certified Small Disadvantaged Business and Woman Owned Small Business, competing exclusively under set-aside vehicles rather than full-and-open competition.
Hanson's federal footprint comprises three small purchase orders across two agencies, all classified under NAICS 82110 (Landscaping Services) and PSC 7210 (Housekeeping, Landscaping, and Groundskeeping). The U.S. Army Corps of Engineers accounts for two awards totaling $24 thousand in combined potential value: a $5,010 firm fixed-price purchase order awarded June 27, 2024, for tree and shrub pruning and debris removal to clear the security fence at the Lake Washington Ship Canal in Seattle; and an $18,900 purchase order awarded June 16, 2025, for ivy removal and Fremont poplar care services, also in Seattle, with ultimate completion scheduled for June 26, 2025. A third award came from the Department of the Army Corps of Engineers Engineering District Seattle — a $22,840 purchase order awarded April 16, 2026, for tree service in Seattle under the LWSC FY26 program, with completion due August 31, 2026. Combined potential value across all three awards is $47 thousand, with $41 thousand obligated (88% of ceiling).
