Intensification Area Urban Design Guidelines - City of Barrie

g) Where occasional compaction of planting soil is
anticipated, the use of soil cells should be considered.
h) Where possible, soil infrastructure should be improved on
boulevards where trees will be planted. This will ensure
the long term health of the tree and benefits to the
community.
i) Street trees should generally be located within the
boulevard and should be offset a minimum of 1.5 metres
from the curb to accommodate snow storage, large
vehicle movements and minimize salt damage. Where this
is not possible, street trees should be located between
the sidewalk and the public right-of-way. For streets
with wider boulevards where the distance between the
sidewalk edge and back of curb was greater than 3 metres,
the distance between curb edge and the street tree would
have a greater setback proportionally.
j) Trees should be spaced consistently at 6.0 to 9.0 metre
intervals (ideally) based on mature size. Additional
distance may be required (10.0 to 12.0 metres) to ensure
appropriate clearances from utilities, street lights and
sight triangles. Sight lines should also be considered in
the location of trees planted at intersections.
k) Consider the type and location of trees to ensure that
higher branching trees do not interfere with large vehicles.
l) Street trees and landscaping should be locally adapted
species. Plants that grow naturally in the City of Barrie
are adapted to the local climate and soil conditions and
can survive with minimum maintenance, use of fertilizer,
pesticide or irrigation.
m) Shrub and ground cover planting should be utilized in
open tree pits, provided the minimum pedestrian clearway
dimension is available.
n) All shrubs and ground cover should be tolerant of urban
conditions, should be noninvasive and be completely nontoxic,
appropriate for use in public areas.
o) Seasonal appeal, especially for the winter months should
be considered for all planting.

Drive, please refer to Section 5.8.
