Urban Forestry mailed reminders to all property owners who were required to plant a tree as a condition of a permit in 2016. Portland’s planting season lasts from October 1 – May 1 each year. To ensure compliance with permit requirements, make sure all required plantings are in the ground by the end of this period. If you have already planted your tree(s), thank you! Urban Forestry staff regularly visits properties to inspect for compliance with tree planting requirements; inspections this year will start in May 2017.  For questions regarding your permit, email trees@portlandoregon.gov or call 503-823-TREE.
