<font size=2 face="sans-serif">If you are going to be looking at planting
trees in Hydro corridors/right-of-ways, and I think it's a great idea,
you need to consider the safe limits of approach to those overhead
lines.</font>
<br>
<br><font size=2 face="sans-serif"> Safe limits are determined by
the voltage of the those lines and no portion of the tree or any part of
equipment that needs to get into the tree to maintain should encroach into
those safe limits. </font>
<br>
<br><font size=2 face="sans-serif">I'm going to assume that anyone you
send to do work on trees that you've planted would be an unauthorized worker
(unauthorized from the stand point of the power authority who owns the
equipment) so the safe limits would be (in Ontario, Section 188, Reg 627/05,
s7) 750 or more volts but not more than 150,00, safe limits is 3 meters,
150,000 to not more than 250,000 safe limits is 4.5 meters, more than 250,000
safe limits is 6 meters. </font>
<br>
<br><font size=2 face="sans-serif">Hydro 1 or any smaller power utility
is going to be exempt from any municipal bylaw that protects trees and
at the end of the day unfortunately the mantra is "clearance before
appearance". Often you'll see some pretty horrific "trimming"
attempts by power line arborists to try and compromise complete removal
when they are pressured but keeping the power on and worker/public safety
from electrocution is going to trump tree preservation any day of the week.</font>
<br>
<br>
<br><font size=2 face="sans-serif">Now having stated that, I just happen
to have in front of me an old easement agreement between a private homeowner
and the Hydro Commission of Ontario which deals with vegetation on ROW.</font>
<br>
<br><font size=2 face="sans-serif">This document deals with a wood pole
transmission line built in the 1940's but not much has changed. The poles
would be 45-50 foot and the construction would be cross arm. Voltages I
believe are 115,000 volts.</font>
<br>
<br><font size=2 face="sans-serif">"( c ) To keep the said land as
described clear of all trees except fruit trees which shall not exceed
twelve feet in height, and to cut or trim from time to time such trees
as the Commission may consider necessary for the operation and maintenance
of the said line and necessary equipment." </font>
<br>
<br><font size=2 face="sans-serif">That agreement gives the utility the
right to access and maintain at their discretion, all the vegetation on
the easement that they determine may interfere with the safe distribution/transmission
of electricity. Small little paragraph but very powerful. </font>
<br>
<br><font size=2 face="sans-serif">Keep all of this in mind when you're
dealing with power corridors and Hydro 1, work with their forester and
respect the safe limits and you should have no issues as long as you don't
impede access to equipment. Hydro 1 controls the corridor and what grows
on it, you're going to need their cooperation. </font>

<br><font size=3>Speaking of short trees in Hydro corridors....</font>
<br><font size=3> </font>
<br><font size=3>Here in downtown Toronto, open space is at a premium and
the city often licenses hydro corridors for use as parkland or trails.
Hydro One reviews site plans for our parkland proposals and they require
that any tree planted in the corridors be "maximum 4.5 m height at
maturity". This doesn't mean "max. 4.5 m if you prune them
diligently". It means a naturally short tree: Hawthorn, Crabapples,
shrubs. </font>
<br><font size=3> </font>
<br><font size=3>My questions to the list (especially utility arborists!):</font>
<br><font size=3>What tree species would be ideal for planting in hydro
corridors in downtown Toronto? I am especially interested in nut trees,
since we've recently had a request for a fruit and nut orchard in a hydro
corridor.</font>
<br><font size=3> </font>
<br><font size=3>Thanks!</font>

Would love to see restrictions for maximum height for trees planted under
overhead power lines but it's likely someone who is scared of tall trees
and wind who made the initial call and, I'll bet that they are senior.

Okay everyone, here’s one that I have never come across before. Our
corporate media person had someone contact them to see if we in Saskatoon
were going to be doing anything about restricting the height of trees in
our city. They claim that some municipalities are already doing this.
I have never heard of this. Has anyone out there heard of this?
I’d really like to know and some of the history behind this.</font><font size=3>
