The City of Hillsboro has been recognized as a 2019 Tree City USA by the Arbor Day Foundation. The City is proud to receive the designation for the second year.

This designation celebrates the City’s dedication to public tree care and promoting the positive effects trees have on our neighborhoods, businesses, environment, and wildlife.

The Arbor Day Foundation sponsors Tree City USA in partnership with the U.S. Forest Service and the National Association of State Foresters. 


According to the Arbor Day Foundation, the benefits of being a Tree City USA include:

  • Reduced costs for energy, stormwater management, and erosion control: Trees yield three to five times their cost in overall benefits to the city.
  • Increased property values: Properly placed trees can increase property values from seven to 20 percent. Buildings in wooded areas rent more quickly, and tenants stay longer.
  • Stronger neighborhood and community ties: Trees and green spaces directly correlate to greater connections to neighbors.
  • Expanded community understanding of the value of trees: Participation in this program provides the opportunity for the community to come together to learn about the value of trees.

Annual Application for Tree City USA Designation

The City of Hillsboro has been recognized as a Tree City since 2018.

Hillsboro’s 2020 Vision and Action Plan and 2035 Community Plan identify Tree City USA as an important sustainability action item.

The City earned the designation by meeting four fundamental standards of sound urban forestry management:

  • Maintaining a tree board or department
  • Having a community tree ordinance
  • Spending at least $2 per capita on urban forestry
  • Celebrating Arbor Day

The City will reapply annually for the Tree City USA designation.

Tree Care Standards

The Hillsboro Municipal Code and practices already met the Tree City USA criteria before the City applied for designation.

The Municipal Code language updates, approved by City Council in fall 2018, did not introduce new responsibilities for Hillsboro community members and contractors, but instead:

  • Outlined existing responsibilities
  • Adjusted the minimum clearance height over roadways from 13 feet to 15 feet (effective January 1, 2020)
