To maintain a healthy and diverse urban forest, the City of Boulder’s Parks and Recreation Department's Forestry Division will be performing necessary tree pruning and removals in Pearl Street Mall from Sept. 20-24.

Blue River Forestry and Tree Care, a city contractor, will prune or remove trees on the 1200 and 1300 blocks of Pearl Street Mall. All tree maintenance procedures are scheduled to take place between 6-11 a.m.

No street closures will occur as work zones are small and will be coned and taped off for public safety.

“We’ve identified five trees that have severely declined in health due to restricted root zones and, thus, pose a public safety hazard if they aren’t pruned or removed,” said Forestry Manager Kathleen Alexander. “All the trees removed will be replaced in the spring with a new species to create better tree species diversity in the downtown area.”

The trees to be removed include three Honeylocust trees on the 1200 block and two Lindens on the 1300 block of Pearl Street Mall. In addition, twelve Honeylocust on the 1200 block will be pruned to remove dead wood.

City park and neighborhood street trees are inspected annually for structural integrity and safety by the Boulder Forestry Division using industry-set standards and techniques. This work is also in line with the Boulder Urban Forest Strategic Plan, which is the guiding document for maintaining the city’s urban canopy and achieving a variety of sustainability and climate goals.
