Arapahoe County Weed Control enforces the Colorado Noxious Weed Act (C.R.S. §35-5.5-101) through its Weed Advisory Board. Property owners must abate listed noxious weeds and keep vegetation under 12 inches. Front Range wildfire concerns drive summer enforcement, especially after the Marshall Fire.
Arapahoe County administers weed control under C.R.S. §35-5.5-101 et seq. (Colorado Noxious Weed Act) via the Arapahoe County Weed Advisory Board. The county maintains a list of State A, B, and C list noxious weeds plus locally designated species. Common targets include Canada thistle, leafy spurge, diffuse knapweed, myrtle spurge, and cheatgrass (a major Front Range fire fuel). Unincorporated Arapahoe County enforces a vegetation height standard of roughly 12 inches on developed lots; vacant/undeveloped parcels receive annual spring notices. Aurora Municipal Code §22-116 requires weeds and grass to be kept under 10 inches. Centennial Municipal Code §7-6 follows a similar 12-inch standard. When property owners fail to abate after notice, the county hires a contractor to clear the property and adds the cost plus a 25% administrative fee to the property tax bill as a lien per C.R.S. §35-5.5-109. The Marshall Fire (Dec 2021) intensified Front Range enforcement because cured grass/weeds acted as primary fire fuel.
Notice to abate with 10-day correction period. County abatement: $200 to $1,000+ depending on lot size. 25% administrative fee added. Tax lien on property per C.R.S. §35-5.5-109.
