DOWNTOWN TREES 

Hillsboro has been a Tree City USA since 2018

Help with the Tree Inventory

Here at Hillsboro Downtown Partnership, we love trees! Shade, beauty, and fresh air are just a few of the benefits of a tree, but to Hillsboro residents they are an environmental asset that contribute to the overall livability of our community. We are working to increase not only the number of street trees in Downtown Hillsboro, but the canopy cover of our district. 

Making improvements always begins with figuring out where we are starting out. And this is where you come in! We are looking for tree lovers to help us inventory and assess the health of all of the existing street trees. You don't have to be an expert to help, you just need a mobile phone with a data plan and fill in as much all the information you observe and then upload that info into our online collection form. 

Here are some tools that might help. 

  • Clothing that keeps you comfortable and visible. 
  • Measuring tape (retractable construction tape or soft sewing tape both work)
  • A free mobile app that measures tree height. Android
  • A free mobile app to identify the tree. Android

Here's the link to the form:

Importance of Street Trees

Street trees provide many benefits including:

  • increase shade
  • improve air and water quality
  • reduce water runoff
  • reduce greenhouse gas emissions cooling of up to 9 degrees Fahrenheit
  • reduce air conditioning needs
  • lower energy bills
  • increase house values (by up to $8870 in the Portland metro area)
  • stimulate the local economy by attracting new businesses
  • buffer traffic noise
  • slow traffic
  • create a sense of place



What is the Urban Heat Island Effect?

The Urban Heat Island Effect occurs when natural settings (like fields, forests, or riparian areas) are replaced by pavement, buildings, or other surfaces that trap heat. The trapped heat near the surface increases the air temperature much faster than rural areas that surround the city. This leads to increased energy costs to cool large areas, increased air pollution, and increased heat-related illness. 

Planting street trees in an urban areas can greatly reduce the negative effects of the Urban Heat Island Effect.
