When Is a Permit Required?

Application and Instructions

Only an owner of the property adjacent to the planting strip, or the owner's designee, may apply for a street tree permit. 

All information in the Tree Attachment Proposal is required. Please be as specific as possible. 

Timeline and Process

The processing times for Street Tree Attachment Permits may vary. Incomplete applications will delay the process.

Once an application is received and deemed complete it will be processed to a Tree Inspector who will perform an on-site inspection.  If the Tree Inspector needs more information or wishes to discuss the application, they will contact the applicant. The Tree Inspector will make a permitting decision and send a Notice of Decision to the applicant.
