Yes, cars do drive down that alley. Note it is not a street but an alley, but those are the front doors to the town homes. The town houses are over 100 years old.

It is the standards that we need to challenge not that trees cannot be grown in denser spaces. Is this an ideal condition for trees, no but far better for the residents that no trees. Please do not think that I am proposing that we can design cities this way, only to illustrate what is possible if the designers were to understand all the issues, design to those issues and the standards allow the tree and pedestrian win.</div><div><br></div><div>Attached, below, is another example of large trees in dense areas, this time on a street with parking on both sides. Note that on one side of the street there are power lines in the trees. These homes are some of the most expensive homes in Annapolis. This block is one of the most favored by walkers in the city despite the narrow irregular sidewalks. Examples like these can be found in Toronto. The owners fight for these trees.</div><div><br></div><div><img id="3225553a-bc9c-4260-b518-fd1db721ebef" height="240" width="320" apple-width="yes" apple-height="yes" src="cid:C3CD52AC-D450-4221-AADF-B01C662F3184"><img id="b230f92e-429f-4477-9725-d0dfba7a545e" height="320" width="240" apple-width="yes" apple-height="yes" src="cid:4DA7C278-C31C-4A69-BD53-8798D9E872F1"><br><div>

Agreed. It would also appear that this picture also touches on a
previous issue that was addressed not too long ago and that being the
need <br>
for adequate soil exposure around the base of the tree. <br>

Friends

<div>Please note the following example from Philadelphia Pa.
Densification does not mean you cannot plant trees or even grow trees.
it is all about the resources needed to accomplish the goals not that
they cannot be accomplished<br>

Kelowna, because much of the new development is happening on
hillsides. In these areas, the roads are narrower and so are the
building lots. In some cases we’ve said we don’t want street trees
because it’s too narrow. However you might be able to work with your
development bylaw and require that the trees get planted elsewhere on
the private property (in the back yard) if there’s enough space. That
way you still get the environmental benefits but not the maintenance
