What you need to know about removal

Mercer Island City Council passed new Residential Development Standards in September of 2017 which included a re-writing of the Tree Code. The City now requires a tree removal permit for the removal of any tree over 10 inches in diameter. In most cases, the permits are free and available at the Permit Center.

• Permit required to remove any tree unless specifically exempted.
• Hazardous tree may be removed before permit application if the tree poses a threat.
• Exempt from permit if tree is smaller than 10 inches and not an exceptional tree or a previously required replacement tree.
• Normal pruning and maintenance requires no permit

Tree removal associated with development has different requirements so if you are planning construction of a house or commercial building, we can help you navigate the new tree code.

Please think twice before removing trees as they are a valuable resource to the Mercer Island community. They slow erosion, increase property values, provide wildlife habitat, clean our air and reduce wind and noise.
