Tree Removal in Critical Areas

Tree removal that is not associated with a development project is not allowed in a critical area (wetlands, watercourses, landslide hazard areas, and buffers). One or more of the following criteria must apply and documentation must be prepared by a qualified arborist showing that:

1. The tree is a hazard;
2. The tree is diseased, in decline, or not viable for retention; or
3. The removal of the tree will enhance the ecosystem functions and values and/or promote slope stability (this report may be prepared by a qualified professional)

If one of the above conditions apply to the tree(s) you wish to remove, include the following with your Non-Development Tree Permit Application:

1. A restoration plan prepared by a qualified professional that contains the following:
   1. Analysis demonstrating how the ecological functions and values including but not limited to slope stabilization, hydrologic function, and habitat value are preserved by the proposed plan.
   2. Proposed removal of all noxious weeds, as defined in Chapter 19.16 MICC.
   3. Removed trees shown as made into snags at a safe height, where feasible.
2. Confirmation that the approved restoration plans shall be completed by a qualified professional.
3. Completed Non-Development Tree Permit Application (for more information about tree removal on private property click here).
