species tree (one (1)tree credit).

e. Replacement Requirements:As pn alternative to retaining trees,
tThe Administrator may authorize the planting of replacement trees, as an
alternative to retaining trees in conformance with subsection H.1.a of this Section,

that an insufficient number of trees can be retained, the proposed removal and
replacement is the minimum necessary to accomplish the desired purpose, and
the tree replacement complies with the following:
i. Replacement Criteria: Replacement planting in lieu of minimum
tree retention may be granted for situations where:
a) There are special circumstances related to the size, shape,
topography, location, or surroundings of the subject property; or
b)The strict application of the code would prevent reasonable
use of property; or
c) The strict application of the code would prevent compliance
with minimum density requirements of the zone; or
d) The project is a short plat with four (4) or fewer lots.
ii. Replacement Quantity and Standards: When the minimum
number of protected trees cannot be retained, replacement trees with at least a

based on the tree credit value of each protected tree removed pursuant to the
table shown in subsection H.1.b of this Section. The protected trees used for
calculating required credit replacement shall be determined based on the priority
order of the significant trees proposed for removal on-site. Replacement trees
shall not contribute to the total credits required pursuant to subsection H.1.b of
this Section. The City may require a surety or bond to ensure the survival of
replacement trees.
iii. Replacement Tree Species: The Administrator shall have the
authority to approve, deny, or restrict the tree species for proposed replacement
trees.

trees cannot be retained, replacement trees, with at least a two inch (2") caliper
or an evergreen at least six feet (6') tall, shall be planted at a rate of twelve (12)
caliper inches of new trees to replace each protected tree removed. Up to fifty
percent (50%) of trees required pursuant to RMC 1 1 070, Landscapin0, may
contribute to replacement trees. The City may require a surety or bond to ensure
the survival of replacement trees.
