<p>So are the trees on the left of the image totally constrained on
their right side with no possibility of roots under the sidewalk?
And are the trees on the right side of the image totally
constrained on all four sides?</p>
<p>My experience would be that the area for the sidewalk / road
would have been heavily compacted (Proctor 90% +) and then the
road and sidewalk laid down. Do you know if the planting pits on
the left side were extended into the grassed area or did the roots
just manage to escape somehow?<br>

<p class="MsoNormal">All, we are having a bit of an internal
debate about standards for local/residential roads and
boulevards. My observation is that trees that are planted in
a boulevard behind a monolithic sidewalk (sidewalk up against
the curb and planting area next to the property) generally do
better. They have access to more soil volume in the front
yard, they get more water and the boulevard is tidier since
the homeowner treats it like part of their yard. Also fewer
issues with roots lifting sidewalks. Some of our staff prefer
the separated treed boulevard, for various reasons. Note, I’m
not talking about busier roads where the trees in boulevards
help to form a barrier from traffic.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We don’t have a lot of good examples here
that directly show a comparison. Does anybody have some photos
that might show the performance of trees on one side of the
road in a separated boulevard, vs. trees on the other side
behind the sidewalk?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Below is an example that doesn’t exactly
show this, but it does show the value of soil volume, with the
trees on the left side being able to access the lawn area
behind the sidewalk, vs. the trees in “coffins” on the right.
These are lindens planted at the same time.<o:p></o:p></p>
