trees shall be retained in the following priority order:
Priority
One
i. Landmark trees:
ii. Significant trees that form a continuous canopy:
iii. Significant trees on slopes greater than twenty percent (20%);
iv. Significant trees adjacent to critical areas and their associated buffers•
v. Significant trees over sixty feet (60') in height or greater than eighteen

Two
Li. Other significant native evergreen or deciduous trees; and
iii. Other significant non-native trees.
Priority
Three
Alders and cottonwoods shall be retained when all other trees have been
evaluated for retention and are not able to be retained, unless the alders
