Noxious Weeds

The Town of Estes Park Parks Division handles the noxious weed control on Town property. Property owners are responsible for weed mitigation and management on private properties and to comply with the Estes Valley Municipal Code (Section 8.04.030 & 8.04.040) referenced on this website. In addition, the Town teams up with the Estes Land Stewardship Association (ELSA) to hold Monitored Weed Drop-offs and the annual Weed Roundup on one Saturday morning, 9:00 AM - Noon, in each month during June, July, August, and September. The annual Weed Roundup with educational materials is held in conjunction with the July Monitored Weed Drop-off. In 2018 the Monitored Weed Drop-offs are scheduled for June 23, July 21, August 25, and September 22. The July 21 Weed Roundup offers in-depth interaction with weed experts to help with weed identification, management, eradication suggestions, and educational materials.

Bring your weeds - no slash, pine needles, pine cones, trash, etc. - in paper yard bags for free disposal. Please remove/shake off dirt from plant roots. Bags will only be accepted during Monitored Weed Drop-off times at the 666 Elm Road site. Unauthorized drop-offs at this location are considered theft of services; this site is electronically monitored. Weeds and trash can be disposed of year-round at Waste Management for a fee. No bags of non-weed materials will be accepted at these events. Paper yard bags are available for purchase at local hardware stores. These events are made possible with the support from the Estes Land Stewardship Association (ELSA), the Town of Estes Park, Colorado Department of Agriculture, Estes Valley Land Trust, Larimer County and individual donors. ELSA meets the first Thursday of the month (January thru November) at 9:30 a.m. in the George Hix Room at US Bank. For more information about ELSA contact
