Are there other regulations pertaining to trees aside from tree removal restrictions?
As mentioned above, new developments must meet tree retention requirements that govern which trees can and cannot be removed when a project is built. In addition, the City limits the manner in which tree pruning and tree maintenance can be conducted. In general, tree topping – radical removal of the canopy of a tree – is prohibited in the City of Issaquah. This pruning regulation prohibits removal of more than 25% of a tree’s canopy during any one pruning event.
