Toothaker HMU Invasive Vegetation Removal

The U.S. Army Corps of Engineers Walla Walla District is soliciting competitive bids for invasive vegetation removal services at the Toothaker Habitat Management Unit at McNary Lock and Dam Operating Project in Finley, Washington. The scope of work includes mechanical removal of invasive Russian olive trees and other invasive vegetation species from approximately 6.25 acres (4.5 acres in a Shoreline Area and 1.75 acres in an Inland Area), with vegetation cutting and mulching to ground level required by May 1, 2026, followed by herbicide treatments during spring and summer of 2026 and 2027. Contractors must meet performance standards requiring 80 percent of vegetation to be 12 inches or less in length and four inches or less in diameter following initial removal work, and must avoid applying herbicides near native plantings scheduled for November 2026. Key requirements include contractor provision of all personnel, equipment, supplies, and supervision, completion of security training within 30 days of award, E-Verify employment verification, and identification of key personnel within 15 calendar days after award. The proposal due date is March 26, 2026, with contracting officer Tracy Gluck, Contracting Officer's Representative Leah Bonstead, and USACE Technical POC Brad Trumbo listed as government contacts.

This is a total small business set-aside opportunity, restricting competition to qualified small businesses. The work will be performed in Kennewick, Washington, with the contract period extending through summer 2027 to accommodate both initial vegetation removal and multiple seasonal herbicide treatment phases. No specific award value or budget range is provided in the available solicitation documents, though the scope encompasses two distinct work areas with defined acreage and treatment schedules. The contractor must possess the capability to conduct both mechanical land clearing operations and chemical herbicide application in compliance with the Walla Walla District's Integrated Pest Management Plan. Interested small businesses should submit complete offers including all required documentation by the March 26, 2026 deadline.
