The Urban Forest Departments routine pruning is responsible for keeping our city beautiful and maintaining the health of our boulevard trees. We operate on a cyclical rotational pruning schedule. Rotational pruning is a proactive, cost effective  approach that allows us to get more work done annually and provides a greater community wide benefit.

Why do we prune trees?

  • Public safety
  • Clearance for signs, signals, street lights, pedestrians and traffic
  • Protect property by removing limbs that may fall and damage property or limbs that are rubbing on buildings

Increase tree health by removing branches that are unhealthy or dead, fixing growth defects and lowering wind resistance.

Tree trunk and basal sprouts, suckers, water sprouts
Property owners are encouraged to remove sprouts from the base or trunk of a tree as soon as they appear in spring while the new growth is soft. Use only hand tools and cut sprouts as close to the trunk as you can without damaging the bark. Sprouts can grow very quickly and are poorly attached. This can create clearance and/or safety concerns. Pruning sprouts improves the health of the tree.

In order to stay on schedule of our cyclical pruning, we will only dispatch crews to a pruning request if there is a legitimate threat to public safety or property.

Reasons you may request pruning

  • Cracked or hanging branches
  • Danger of car or truck hitting a large branch
  • Branches rubbing on house

We will not prune a boulevard tree

  • To improve a view, for aesthetics, or to provide more light for solar panels If it blocks a commercial sign.
