Portland is committed to improving the city’s air quality, public health, and livability by enhancing and maintaining the health of the urban forest, investing millions of dollars each year planting trees.

Tree preservation and tree density requirements apply to many development projects, including new construction, additions, and exterior renovations. When applicable, tree requirements will be reviewed as part of your building permit application.

Portland's trees provide numerous services to the city, such as stormwater interception, reduced air pollution, urban heat island mitigation, and wildlife habitat.
