Subject: Best Bu - Landscape Plan and Tree Replacement
{KPH Staff -
I have reviewed the plans submitted for the Best Bu project re the tree inventor and the
landscapin and have the followin comments:
1. Tree Inventor (Site Visit 10/18/07)
a. The number of trees as well as tree sizes present on the site are accurate
b. The tree species are not all accurate - there are a number of Fraser fir on site, especiall trees on the S
end of
the parcel, N of Menard's parkin lot. These trees were identified on the tree inventor as white
spruce.
c. Tree Condition: I would classif most trees on this site as bein in "fair" condition due to some minor
problems with dead/broken branches, g aps, brownin needles due to drou stress and for minor
issues
with tree form.
d. Transplantable Trees: All but about six trees are in g ood enou condition to be transplanted. Some of
the
spruce have lower dead branches which ma indicate infection with C canker. Trees which
are not
in ver g ood condition and are not considered transplantable will be marked with oran fla
e. Total inches of trees to be transplanted are 218 minus approximatel 40 diameter inches = 178 in.
2. Conditions for Transplantin
a. an 85 in. diameter tree spade should be used for ever trees 14-18 ft. tall (per N1ND0T
landscape spec's.
b. trees should be moved prior to June I st or after Sept. I st, not durin the summer
c. g aps between ed of holes and root balls should be filled in before mulchin
d. trees should be mulched with 4 inches wood chip mulch
e. trees should be watered well (root areas soaked) once per week durin I st and 2nd g rowin g seasons,
unless there is sufficient rainfall to provide ade moisture for the trees
*f. transplanted ever trees from this site should be g uaranteed for 2 y ears from installation date
3. Tree Replacement Re
All 21 diameter inches of trees on the site are to be removed for development. Trees will be replaced
b the trees moved on site (approx. 178 diameter inches and the trees to be provided in the landscape plan
(approx. 182 diameter inches). These diameter inches (360) exceed the inches removed, so no additional
tree replacement is re *To insure that lar on-site ever which are transplanted survive the
transplantin process and recover period, a 2 y ear g uarantee should be provided for these trees.

4. Landscape Plan
a. The tree and shrub species are fine, being varied, relatively insect and disease resistant, well- suited to
the site conditions and hardy in Minnesota
b. The size and type of nursery stock to be used are appropriate and meet code requirements
c. The plan is attractive and complements the land use. The landscaping fulfills appropriate aesthetic and
screening functions
5. Planting Detail and Notes
The developer should add the following to the Planting Detail/Notes:
a. evergreens transplanted on site to be guaranteed for 2 years from date of planting
b. remove twine from base of trunks of B &B materials
c. remove top rungs of wire basket, if present, before back - filling B &B materials
d. cover root balls of trees and shrubs with soil before mulching
