Tree Removal Justification
Per building setback requirements in the Land Use Code, the Powerhouse 2 building will be situated in
close proximity to College Avenue and Vine Drive. Placing the building is this location requires removal
of 5 existing trees located in the southwest corner of the property.
Additionally, with development of this property, the Land Use Code requires Vine Drive to be expanded
to serve the property. The Vine Drive Improvements include reconstruction of the north half of the
street (including a travel lane, bike lane, curb/gutter) a 10’ tree lawn, and a detached sidewalk. City staff
also asked that we explore adding on-street parking on Vine Drive. The addition of these public
infrastructure improvements along with the proposed redevelopment requires removal of 5 additional
trees located on the south edge of the property between College and Jerome.
Existing trees being removed are summarized as follows:
Tree ID # Species Stems DBH (inches) Condition Forestry Mitigation
1 Siberian elm 2 17, 18 fair minus 2
2 Siberian elm 26 fair minus 2
3 Siberian elm 29 fair minus 2
4 Siberian elm 26 fair minus 2
5 Siberian elm 37 fair 3
6 Honey locust 16 fair 1.5
7 Honey locust 7 19 fair 2
8 Siberian elm 2 - 7 fair minus 1.5
13 Silver maple 40 fair minus 3.5
14 Douglas fir 6 fair 1
Tree identification numbers above relate to tree numbering shown on the Tree Mitigation Plan which is
included in the PDP submittal. Refer to the Tree Mitigation Plan for specific tree locations.
To offset the loss of the existing trees, 20.5 mitigation trees will be planted on site, or off-site in a
nearby location.
