Trees (Urban Forestry)

The City of Arvada is home to a diverse and beautiful array of wildlife and plants. Trees are a major part of the City’s infrastructure, providing both beauty and supporting vital ecosystems. Our goal is to help promote and preserve Arvada's urban forest.

What Trees Do For Us

  • Shade and cool our homes
  • Clean our air and produce oxygen
  • Help reduce soil erosion
  • Lower utility bills
  • Protect rivers and streams
  • Provide homes for birds and other animals
  • Add beauty and enrich our lives

What the City Forestry Team Does

  • What do we do? We care for trees!
  • Prune trees for aesthetics, health and safety
  • Remove trees and branches to eliminate hazard conditions
  • Plant trees with an emphasis on diversity
  • Identify, diagnose and treat tree ailments
  • In the past, we have provided free mulch to residents, but during the construction of our new parks maintenance facility, we will not be offering mulch.

What You Can Do

Assess the health of your tree and provide maintenance as needed.

Signs of a healthy tree

  • New growth: A healthy tree produces new growth yearly on both its trunk and branches.
  • Healthy branches: Branches should show signs of leaf budding and/or new growth• Strong bark: Healthy bark is free of fungi, large holes and cracks.
  • Plenty of leaves for deciduous trees; plenty of needles for evergreens.

Tips for maintenance

  • Prune dead, dying or broken limbs.
  • Inspect for insect damage or disease. If signs are present, contact a tree specialist for treatment options.
  • Deep water trees year round (in warmer temps)
    • Trees should be watered every 3-4 weeks even throughout the winter months.
    • Special attention should be given to evergreens such as Spruce, Pines and Firs and all trees planted within the last 3-5 years.
    • Water when temperatures are above 40 degrees and during mid day so the water has a chance to soak in.
    • Apply water out to the drip line (the area around the trunk out to under the outer most branches).
    • A general rule is to apply 10 gallons of water for each diameter inch of tree trunk measured 6" above the ground.
    • If using a water probe or needle do not go down more than 8-10". Going deeper will put much of the water under the root system. It is also important to close all holes so the water is not wicked out.
  • Apply mulch
    • To help reduce soil evaporation, improve water absorption, insulate against temperature extremes and reduce weed growth, apply between two and four inches of wood chips around the base of the tree, but not touching the tree trunk.

Plant a Tree 

The City of Arvada Plant A Tree Program is designed to inspire our residents and promote the planting of trees in the city's parks and open spaces, as a rewarding and unique means of paying tribute, honoring, commemorating or celebrating special times.

The donor chooses the type of tree based on the recommendation of the city forester. The type of tree must be appropriate for both the park and the planting location. The forestry department will then select the tree, purchase it and make arrangements with the tree donor for the tree planting. Tree prices range from $225 to $350.

For more information and to discuss tree type/park location for the Plant a Tree Program, contact our City Forester Ian MacDonald at imcdonald@arvada.org.

Donate a Tree 

If you have a tree on your property that is in the way of construction or has outgrown its present location, the City of Arvada's forestry division will consider transplanting it to one of Arvada's many parks.

We will visit your site to determine if the tree is suitable to be moved. Donations to the City are tax deductible.

Contact City Forester Ian McDonald at imacdonald@arvada.org for more information.
