Traffic on Broadway Between College and University Avenues to Be Reduced to Single-Lane Travel April 1 for Tree Removals

City of Boulder crews will remove 20 non-treated ash trees on the Broadway median between College and University avenues April 1, weather-permitting.

This tree work is taking place to mitigate safety issues caused by the potential for falling limbs from dead and dying trees. All 20 of the ash trees being removed are affected by Emerald Ash Borer (EAB), an invasive wood-boring beetle prevalent across the U.S.

The work will require a closure of both the north- and southbound interior lanes of Broadway between College and University avenues on April 1 from 9 a.m. to 5 p.m. Traffic will be reduced to one lane of travel during this time and signage will be onsite to guide pedestrians and cyclists.

Staff recognize the importance of trees located within the median providing aesthetic and environmental benefits, however at this time staff will not immediately replace the trees based upon inadequate irrigation and the size constraints of the planting areas in the median. The Transportation and Mobility Department is working on estimations for possible future replacement in consultation with the city’s Forestry Division.  Future improvements will be planned to provide adequate planting areas and irrigation to ensure the long-term survival of new trees that are planted.

EAB attacks all North American ash trees (Fraxinus spp.) not protected by pesticides. Now well established across the eastern and midwestern U.S., EAB has killed hundreds of millions of ash trees over the past two decades. All public and private ash trees in Boulder are currently at risk. Declining public and private ash trees will require removal before they present an unacceptable level of risk to public safety. As EAB populations in Boulder continue to increase, ash trees are expected to die at an accelerated rate. Residents can expect to see increasing numbers of ash tree removals across the city in coming years. To learn more about the City of Boulder EAB Plan, please visit EABBoulder.org.

The city would like to remind residents that when contracting the removal of a tree on their property, they should be sure to use a tree care company licensed through the City of Boulder. A list of licensed arborists and more information about the Boulder Forestry is available at BoulderForestry.org.
