What Beaverton Arborists Do...

Beaverton prides itself on, and is dedicated to, its trees.

Beaverton’s Urban Forestry Maintenance section provides care and maintenance for the city’s urban forest enhancing the health of existing resources while encouraging conservation and preservation. Arborist technicians annually prune more than 20,000 city trees, providing additional care for a record number of trees, all the while maintaining the highest percentage of trees in ’excellent’ and ’good’ condition for more than 5 years.

The city also aspires to increase the inventory of trees in the urban forest by managing the Development Tree Program, encouraging partnerships with community based groups to complete tree planting projects. The city arborists are also responsible for offering educational classes/materials related to arboriculture and professional arboriculture assistance to residents.

We can address any landscaping or tree questions you may have; please fill out the Report a Problem form or contact Jered Lane at 503-526-2237 or Steve Brennan at 503-526-2206 for any immediate concerns.

Leaf removal is an important part of city landscaping to avoid slippery sidewalks and flooded street drains. City crews sweep and shovel up as much as possible, but it’s important for Beaverton residents to do their part; please avoid blowing/raking leaves into the public paths and streets. Deposit leaves into the yard debris bin provided by Waste Management, or take advantage of Beaverton’s leaf disposal services every fall.

Things to Remember with your Trees 

  • Do not top your trees. Topping a tree promotes sucker growth and produces multiple weaker branches at the top of tree. 
  • Cut dead wood out of trees and shrubs. 
  • Monitor for insects and only treat them when the tree cannot support the number of insects and/or they are causing physical damage to the tree. 
  • Keep vegetation within the right-of-way and at corner lots at acceptable heights (below 3 feet for visibility reasons). 
  • Remove tree suckers from base of the trees. 
  • Water young street trees (planted 2 years or less) at least once a week with approximately 15 gallons of water. 
  • Remove the tree stakes from young trees after the first year. Tree stake ties will prohibit proper growth if not removed. 
  • Don’t dump landscape materials into the street. During heavy rain events it will wash into the inlets and plug the water’s way, which could cause flooding.

Tree Pruning the Basic Cuts 

It is important to prune your tree the right way, the health of the tree depends on it. Whether you are training a tree to grow a certain way when it is young or removing dead branches. If you cut them the proper way it will heal better and be less susceptible to problems, such as: Cutting too close into the branch collar will cause the tree to not heal over correctly and may cause a cavity to form over time; also cutting too far away from the branch collar will cause a branch stub which will prevent the tree from healing over the part of the branch left over. Below is a diagram of the three-cut method that will insure that a proper cut has been made. 

  1. First make a bottom cut to prevent peeling of bark down the side of the tree trunk. 
  2. Then cut off the bulk of the branch. 
  3. Last step is to cut off the remaining stub at the branch collar; this enables the tree to compartmentalize over the wound. 

If these instructions are followed your tree will be in good health and after time the cut will no longer be noticeable. This is the basic technique for removing small 1 ½ inch to 4 inch branches. Branches less than 1 inch may only require one cut, And branches over 4 inches may require many other cuts further out on the limb to remove more end weight prior to finishing with step 3.
