Summary
Greeley bans growing, selling, offering or knowingly allowing any noxious weed on its designated list, and the city can enter property to eradicate infestations and bill the owner for the cost.
The weeds designated in the noxious weed management plan are hereby declared noxious and, as such, are declared a threat to the economic and environmental value of the land within the city, and it is hereby decreed that no owner, tenant or agent shall allow any such plant growth to occur on any lot, block or parcel of ground, including those areas adjoining public rights-of-way.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Municipal Code: Supplement 6 Update 1).
Full Breakdown
Under Section 12-606(g), every plant on Greeley's noxious weed management plan is declared a threat to the city's economic and environmental value, and no owner, tenant or agent may let one grow on their land, including areas next to public rights-of-way. Section 12-606(b)(3) separately makes it unlawful to intentionally introduce, cultivate, sell or offer for sale any designated noxious weed. The management plan itself is on file with the Community Development Department and the City Clerk's office and can only be updated after a public hearing with 30 days' public notice.
Violations & Fines
Noncompliance after a seven-day notice lets the city eradicate the weeds itself and bill the owner the full cost plus $50 and a 20 percent surcharge, recoverable as a lien on the property.
