[CANUFNET] Private Tree Protection

[Michael Richardson]

The trunk formula method is obsolete, it has been replaced by the Trunk
Formulae Technique.

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

If you wish to calculate the value of a tree on a development site then in
all likelihood the value is negative as it will be a cost to the developer
to maintain and it may be used to sterilize development rights and reduce
development footprint which reduces profit and is a negative CREMV.



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