tree removal permit, or on parcels zoned other than single-family (R-1) or low density
residential (RE, R-2, or RMD), the director of planning and development services authorizes
the removal through staff level architectural review pursuant to Section 18.76.020(b)(3),
having determined, on the basis of a tree report prepared by a designated arborist and

12 0010_20240212_mv30
the death of the tree, and there is no financially feasible design alternative that would

financially feasible design alternative that would allow for preservation of the tree(s). For
the purposes of this subsection (a)(2), a financially feasible design alternative means a design
alternative that preserves the tree(s) and would not increase the project cost by more than
twice the reproduction cost of the tree(s) or ten percent of the given project valuation,
whichever is greater. All tree protection zones impacting buildable area are included in the
reduction of buildable area calculation.
(2) (3) The tree could be removed due to the conditions listed in Section 8.10.050(a)(1)(i),
(ii)or (iii) and treatments or corrective practices are not feasible.

necessary to repair a geologic hazard (landslide, repairs, etc.), in which case only the protected
tree or trees necessary to allow access to the property or repair the geologic hazard may be
removed.
(2)The tree could be removed due to the conditions listed in subsection (a)(1)(i), (ii), or
(iii)and treatments or corrective practices are not feasible.
(d)In the case of development requiring planning approval under Title 18, and not included
under subsections (b) or (c), a protected tree shall not be removed unless determined by the
urban forester, on the basis of a tree report prepared by a designated arborist and other
relevant information, that anyeither of the following apply:
(1) Retention of one or more treesthe tree would result in reduction of the otherwise-
permissible buildable area of the lot by more than twenty-five percent, and there is no
financially feasible design alternative that would permit preservation of the tree(s),, where
financially feasible means an alternative that preserves the tree(s) unless retaining the
tree(s) would increase project cost by more than twice the reproduction cost of the tree or
ten percent of the given project valuation, whichever is greater. All tree protection zones
impacting buildable area are included in the reduction of buildable area calculation.
(2)The tree should be removed because it is dead, hazardous, or constitutes a public
nuisance under Section 8.04.050. In such cases, the tree protection zonedripline area of the
removed tree, or an equivalent area on the site, shall be preserved for mitigation purposes
from development of any structure.

woodland and riparian landscapes as the key ecological basis of the urban forest with focus
on native species and habitat," or
(ii)Uses climate adaptive, drought tolerant species.
(e)In any circumstance other than those described in subsections (a), (b), (c), or (d), a

dead, is hazardous, or constitutes a public nuisance under Section 8.04.050.
8.10.055 Tree replacement.
(a)In the event a protected tree is removed pursuant to Section 8.10.050(a)(1)(i), mitigation
for the removed tree, replacement tree ratio, in lieu fees, or a combination thereof shall be
