Noxious Weed Removal

The City of Wheat Ridge, Colorado is soliciting proposals for noxious weed removal and herbicide application services through a Request for Proposals issued February 2, 2026. The procurement covers approximately 72 acres of infested open space (including Lewis Meadows, Wheat Ridge Greenbelt, and Lena Gulch), 9.85 acres of non-irrigated parkland (Baugh property, Creekside Park, Founders' Park, Hopper Hollow Park, and areas south of the Recreation Center), and specified right-of-way areas totaling 5 acres. Services include three annual treatment cycles for open space areas, three annual treatments for poison hemlock and poison ivy along trail margins, two annual applications to parkland areas, and two annual broadleaf herbicide applications to right-of-way areas. The City prefers contracting with a single qualified firm using their own staff, though reserves the option to award to multiple firms. All applicators must hold current Colorado Department of Agriculture licenses, maintain commercial general liability insurance of $1,000,000 per occurrence and $2,000,000 aggregate, and achieve a minimum 75 percent kill rate on first applications with any additional treatments provided at no cost to the City. Contractors must provide 72 hours advance notice before herbicide application and respond to City requests within three business days. Questions are due by February 10, 2026 at 2:00 p.m. Mountain Time, and proposals must be submitted via the OpenGov Procurement portal by February 26, 2026 at 2:00 p.m. Mountain Time, with an anticipated contract date of March 4, 2026. Pricing proposals should be submitted on a per-acre basis for the three service categories, and all prices must remain firm for one year after acceptance.

The City of Wheat Ridge does not require set-asides for disadvantaged business enterprises but affords them full opportunity to bid without discrimination. No incumbent contractor has been identified for this procurement. The contract term is one year with options to renew for four additional one-year periods and may be extended on a month-to-month or cycle basis pending completion of a new solicitation. Subsequent price increase requests are limited to no more than one adjustment per contract term and capped at 10 percent of the original cost, subject to City approval. Invoicing occurs monthly with payment due within thirty days of receipt via Electronic Funds Transfer, and the City is exempt from sales and use taxes. While specific budget figures are not disclosed in the available documentation, the scope encompasses treatment of approximately 308.5 acres of open space annually for three cycles, 9.85 acres of parkland for two cycles annually, and 5 acres of right-of-way for two cycles annually, with pricing to be determined through the competitive proposal process.
