  • Public trees - managed by the Urban Forestry Program

  • Private property trees - regulated to an extent by the city to prevent unnecessary damage or removal.

Benefits of Trees

Trees provide communities with environmental, social, and economic benefits referred as "ecosystem services." Most tree benefits have been thoroughly researched and assigned an actual dollar value.

  • Shade from trees reduces incidence of skin cancer
  • Deterrent to climate change and sequester carbon dioxide
  • Filter pollutants and produce oxygen
  • Reduces the heat island effect
  • Control storm water, flooding and soil erosion
  • Decrease heating and cooling costs.
  • Increase real estate values
  •  Attract shoppers, increase business activity and profits by at least 12%
  • Provide and improve wildlife habitat
  • Recharge groundwater and improve water quality
  • Create visual barriers
  • Reduce the incidence of crime
  • Improve mental and physical health
  • Enhance community spirit
  • Lower incidence of neonatal problems

Why Tree Topping is Harmful

There are plenty of good science-based reasons that topping trees is terrible for tree health.

It has been discredited as a pruning practice for decades, a fact the arboricultural industry has been promoting years. Good urban forestry programs do not allow tree topping as part of their best management practices and tree trimming standards.

  • Topping stresses and often kill trees because it removes the leaves that produce food for the tree. The resulting wounds expose the tree to insect attacks and diseases.

  • Topping cuts create decay. The rapidly growing sprouts that emerge at that point as the tree scrambles to grow new leaf cover pose a high risk to public safety because they are weakly attached.

  • Topping destroys a tree's natural shape and is very ugly because trees have an excellent natural shape unique to each species.

  • Topping is expensive and unnecessary, creating an ongoing liability – if the tree survives - which is costly to maintain and makes for a future hazard where the tree has to be removed and replaced.

  • Topping is prohibited by city code and can result in thousands of dollars in fines and replacement costs.

  • Topping jeopardizes our Tree City USA status, a highly prized designation for cities that value their trees and exemplify good environmental stewardship.

Tree Maintenance Program

Street Tree Replacement Program

Provides funding for the purchase and contracting of trees. Applies only to tree planting at locations where trees were removed the previous years. A new tree planting program is planned for the future to provide over 3,000 identified sites for new street trees.

Street Tree Maintenance Program

  • Pruning public trees for clearance over streets, sidewalks, street lights, and traffic signs identified as high priority locations
  • Removing public trees that have died or pose a high risk to public safety. The #1 Priority Tree Removal Program tree work is contracted to tree service companies through competitive bidding.
  • Special Programs are budget dependent and address tree and sidewalk heaving issues. These programs are a partnership between the Urban Forestry Program and Public Works. 
  • Emergency Tree Maintenance Services address immediate tree concerns of extreme risk. On-call agreements exist with various tree companies to expedite the removal process. 
  • Tree Watering Program over 330 street trees are hand watered each summer using a contracted 4,000 gallon tanker.

Public services

  • Street tree questions and assistance
  • General information on yard trees
  • Site visit to assist with tree and landscape issues
  • Other tree informational resources available
  • Site Development inquiries related to tree retention and landscape design review
  • Tree planting and maintenance training for neighborhood groups
