Colo bamboo herbicide treatment

The National Park Service Northeast Region is soliciting proposals for invasive species herbicide treatment services at Colonial National Historical Park in Yorktown, Virginia. The contractor will be responsible for treating 8.76 acres of land across four locations (Tobacco Road, Moore House, Cornwallis Cave, and Windmill Point) that have been infested with Golden Bamboo, Empress Trees, Chinese privet, Chinese Wisteria, and English Ivy. The work involves applying a 5% glyphosate solution with non-ionic surfactant and blue dye using ground sprayer equipment, with treatments occurring in spring when vegetation has resprouted and a follow-up application 14 days later. Contractors must hold a Virginia Certified Pesticide Applicator License and demonstrate technical capability through a project narrative along with three examples of similar projects from the past five years. The evaluation will be based on price, technical capability, and prior experience, with the award going to the lowest-priced responsible offeror meeting technical specifications. A mandatory site visit is scheduled for July 11, 2025, at 10 AM at the Visitors Center, and proposal submissions are due by July 18, 2025.
