Boulder County removes ash during the cold season from September to April to avoid the times when the Emerald ash borer is in flight and therefore avoid spreading the bug more. Trees marked with blue “X”s will be removed during this time.
Ash trees in the right-of-way will be removed unless they are being treated by an adjacent homeowner or homeowner’s association. Permit holders are responsible for scheduling and paying for treatment in accordance to the terms and conditions.
For more information, tree removal maps, and to apply for a permit visit www.BoulderCountyEAB.org
Most EAB chemical treatments should be applied in the spring when the trees are leafing out for best results.
Contact a licensed applicator to get on their list for spring treatment.
