To maintain a healthy and diverse urban forest, the City of Boulder’s Parks and Recreation Department’s Forestry Team will be performing necessary tree pruning, hazardous tree removal, and ash tree removal in the Fourmile Canyon Creek area north of Pleasant View Fields Sports Complex between 47th Street and East Palo Park.

The natural lands area will be closed starting Monday, Nov. 7 with work happening from 8 a.m. to 5 p.m. each day. The project is planned to continue through the end of the year.

The work will also include removing dead and downed trees from Fourmile Canyon Creek to improve its flow.

City park and public street trees are inspected annually for structural integrity and safety using industry-set standards and techniques. The Forestry team is conservative when determining if a tree must be removed. Trees are removed due to structural concerns, poor health or if they are diseased/infested with Emerald Ash Borer (EAB). Now present in 30 other states, EAB has killed hundreds of millions of ash trees over the past two decades.

The city is partnering with Mile High Flood District and Arbor Force to complete the tree work.

No closures are anticipated to Fourmile Creek trail or East Palo Park.

The Forestry team manages approximately 51,000 public trees in city parks and street rights-of-way, so this work helps keep our streets, sidewalks, and our urban canopy clean and maintained for our community.
