<p>As a professional planner, I would love to know what 'true
planning' is.</p>
<p>The carbon sequestration concept is more myth than reality. Most
studies suggest that urban trees sequester around 1.4 to 1.7% of
the carbon produced by human activities. In effect a largely
irrelevant amount as an offset. I don't doubt developers will
embrace whatever they can to get approval and planting trees is a
very cheap additional cost, far less than saving them and working
around them where feasible. But we need to get away from the idea
that one of the main benefits of urban forests is carbon
sequestration. Health benefits and enhanced livability are far
higher economic benefits and area much better justification.</p>

If it involves true planning then the cost of trees will be a
savings when owners or tenants are involved in planning ,
planting, maintenance, monitoring and reporting!<br>
<br>
Trees carbon sequestered and carbon dioxide drawdowns can be
used to offset the building emissions and if properly built
hold water and save taxes <br>
and don’t forget grey water usage <br>

Developers who get these concepts have been building and

it has been replaced by the Trunk<br>

The TRM or TFT do not "apply" a value to a tree but rather
both are<br>
calculations of the cost of reproduction. Cost is not value!<br>

If you wish to calculate the value of a tree on a development
site then in<br>
all likelihood the value is negative as it will be a cost to
the developer<br>

I developed the City of Cambridge private tree bylaw based
on the economic<br>
disincentive concept. It uses the trunk formula method to
apply a value<br>
to any trees protected within scope of the bylaw; anyone can
get an<br>
approved permit if they pay the fees. While the trunk
formula method<br>
isn't the best fit for every situation, it is a reasonable
standard that<br>
the public can understand and apply. The fees go into a
reserve account<br>
which funds a tree planting program operated by a local
not-for-profit<br>
REEP (<a class="moz-txt-link-freetext" href="https://reepgreen.ca/trees/">https://reepgreen.ca/trees/</a>) that plants trees back on
private<br>
property (no funds are used for city tree planting). It
applies to<br>
development and non-development scenarios. You can review it

Subject: [External] Re: [CANUFNET] Private Tree Protection<br>
<br>
Hello Folks,<br>
<br>
Council has asked Halifax Administration to investigate
options to<br>
incentivize tree retention on private lands scheduled for
new development<br>
(subdivisions etc.). I am curious if other municipalities
have conducted a<br>
similar jurisdictional review that they might be willing to
share, or have<br>
any experiences with private tree bylaws or other planning
tools used to<br>
either incentivize, disincentivize or compensate for urban
canopy loss in<br>
greenfield development?<br>
<br>
I know some of you may have already responded to a colleague
of mine via<br>
the CUSP mind hive, and thank you.<br>
