Street Tree Planning Study

In early 2025, the Seattle Department of Transportation (SDOT) launched the Street Tree Planning Study as a pilot project to identify tree planting opportunities, assess community support, and understand local concerns in four census tracts—Roxhill, South Park, SODO, and Capitol Hill/Olive Way—that represent conditions across the city. These areas were selected based on their diverse land uses, varying levels of existing tree canopy, and unique environmental challenges.  

Funded by the Washington State Department of Natural Resources Urban and Community Forestry Program, the study was conducted in support of the city’s goal to achieve at least 30% tree-canopy coverage across all public and private spaces by 2037.
