What you need to know about tree removal on Mercer Island

Mercer Island City Council passed new Residential Development Standards on September 19, 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.

What is a critical tree area?

  • Geologic hazard area prone to erosion, sliding, earthquake or geological event (see City geologic hazard map)
  • Protected slope area or watercourse corridor (see City watercourse maps)
  • Wetland or any area within 25 ft. of the wetlands edge
  • Areas which restricts removal of vegetation or trees, such as a Native Growth Protective Easement (NGPE)
