Urban Forestry (Trees)

Trees overhanging power lines: Removing limbs from power lines is extremely dangerous. Please contact Xcel Energy by calling 1-800-895-4999. More info at

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 You Can Do for Your Trees

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.

Prepare Your Trees for Winter

Nov. 1 until early April

  • Wrap all young thin-barked trees such as Lindens, Oaks, Honey Locust and Maples with commercial tree wrap from the ground up to the first branch.
  • Place some type of organic mulch two to three inches deep around the base of the tree. Be careful to keep it back from the trunk.
  • If the winter is dry and the ground isn’t frozen, try to water the area from the trunk to the outer-most branches at a rate of 10 gallons per diameter inch of trunk once per month.

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).
  • 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.

Free Mulch

The Parks Department provides free mulch to residents when it is available. Mulch can be picked up in the parking lot at the Disc Golf Course at 17925 West 64th Parkway just east of Highway 93 on 64th Avenue below the Arvada Blunn Reservoir. You load. You haul.
