Here is a cop of the memo I sent to Scott.
Kath
I have reviewed the plan for the trees around the proposed
SANS stadium and have visited the site. I have the followin
comments:
1. Trees to be protected or transplanted: The spruce trees, both
those indicated to be protected in place, and those which are to be
transplanted, are not in ver g ood condition. Man of the white
spruce have severe dama from y ellow-headed spruce sawfl and the
Colorado spruce are sufferin from drou stress, Rhizosphaera
needlecast and C canker. Of the 12 trees indicated on sheet
C1 to be protected in place, 6 are essentiall dead or in ver poor
condition. Of the 17 trees indicated on sheet C1 to be transplanted
on site, 7 are in ver poor condition. Trees which are in poor
condition are not g ood candidates for either preservation or
transplantin M recommendation would be to remove the trees which
are in ver poor condition, and onl protect or transplant trees
which are health and attractive in appearance. Additional
ever ma need to either be purchased or transplanted from the
Environmental Learnin Center in order to replace the 13 trees which
will need to be removed.
2. Trees alon west propert line and berm: Plantin new or
transplanted ever alon the propert boundar to the west of
the stadium is a g ood idea. At this time, 10 trees are indicated on
the landscape plan to be added to that area. I recommend doublin
the number to 20 and usin trees which are at least 8 feet in hei
These trees could be planted on the stadium side of the berm on level
g round. Onl health trees of attractive appearance should be used
and I recommend var the species b addin some white or red pine
to the spruce.
3. Tree maintenance after plantin Trees which are
planted nurser stock or transplanted from elsewhere on site, will
need to be watered well at plantin time and at least once per week
durin the first two g rowin g seasons, dependin on weather
conditions. Ever of this size ( 8-16 feet tall will each
re at least 20 g allons of water a week, provided in one or two
waterin Trees should be mulched with 4 inches of woodchip mulch
from j ust outside the trunk to j ust be the branch spread.
4. Su for vines on boundar fence: There was a su to
add vines to the existin fence. This would have no effect on either
noise or si abatement, particularl since leaves will not be on
the vines during most of the times that ti stadium would be used
(fall and spring). The vines would also require maintenance which
could better be spent on maintaining the transplanted evergreens to
be used for screening. Some native vines, such as Virginia creeper
and riverbank grape, will undoubtedly seed in along the fence and
grow naturally.
In conclusion, the SANS project will require removal of 13
trees and the planting /transplanting of 23 (13 replacements and 10
additional).
