Stakes shall be attached to the tree with No. 12 gauge
galvanized wire covered with rubber or plastic hose where wire is likely to
come in contact with the tree trunk. An alternative may be any of the commercially
available materials designed for staking trees with the approval of the Planning
Board. The loop in contact with the tree shall be loose enough to permit growth
and prevent grinding for two years but shall be tightly bound to the stake
to prevent slipping.
Wood chips partially rotted or nitrogen enriched may
be used. New wood chips are not acceptable because of the bacteria drawing
available nitrogen from the soil, thus preventing its use by the plants it
is intended to protect.
Plant species should not be of the exotic variety requiring
substantial maintenance or be materially affected by pollution, salt damage
along highways or current insect manifestations.
The grade of land located within six feet of an existing
tree that will remain on the site after construction shall not be raised or
lowered more than six inches unless compensated by welling or retaining wall
methods.
For existing trees that will remain on the site after
construction, no vehicular equipment is to be driven within six feet of such
trees and no building materials may be stacked or stored within six feet of
such trees.
The existing natural trees remaining in the area under
construction shall be pruned to remove dead and diseased limbs and trees and
offensive vines and undergrowth.
