Trees are amazing creations that enhance our daily lives. They provide the aesthetic qualities of beauty, color, and form; especially in our urbanized landscapes. Greeley loves trees. In fact, we have been a Tree City USA for over 30 years!

In order to keep Greeley green, we do the following:

  • Maintain trees and shrubs in our parks and public grounds.
  • Monitor for damaging insect and disease issues
  • Test, license and monitor shade tree contractors
  • Enforce City codes for tree maintenance and planting
  • Manage a Memorial Tree and Tree Donation Program
  • Plan, implement, and maintain the public floral displays
  • Provide consultations to citizens, as time allows
