Colorado law makes every landowner responsible for managing noxious weeds. Weld County enforces the Colorado Noxious Weed Act through Chapter 15 of the County Code; if you ignore a notice, the county can control the weeds and bill you, with unpaid costs becoming a property lien.
Under the Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5), all public and private landowners have a legal duty to manage designated noxious weeds so they don't spread to neighbors. Weld County administers this through Chapter 15 (Vegetation) of the County Code and its Weed Management program: an authorized agent may inspect land and issue a Notice to Control Identified Noxious Weeds. List A and List B species carry mandatory eradication or containment requirements. This is separate from ordinary tall-grass nuisance rules and applies across unincorporated Weld County's vast agricultural acreage. Cities (Greeley, Evans) enforce their own weed provisions within their limits.
If a landowner ignores the county's notice, the agent may control the weeds and assess the whole cost plus up to 20% for inspection against the land; unpaid assessments become a lien.
