Project Description:
This project is measuring the benefits of the public street trees throughout Pasadena to quantify the economic and health benefits they provide. This analysis is especially focusing on the air quality benefits of the urban forest to help address major challenges for the city: air pollution and smog. Additionally, the assessment is highlighting energy savings, carbon dioxide reduction and property value increases. This assessment is being used to inform the city’s future Urban Forest Management Plan.

    • $1.36 million in air quality benefits.
    • More than $260,ooo in energy savings.
    • More than $151,000 in carbon reduction benefits.
  • The trees’ replacement cost would be more than $308 million.
  • Pasadena’s street trees provide 663 acres of canopy cover, shading around 27 percent of streets and sidewalks.
