This document discusses why trees near power lines need to be trimmed or cut. It notes that trees can pose safety hazards by potentially causing electrocution if they touch power lines, and can also cause power outages if their branches break during storms. The document outlines minimum clearance zones around power lines to prevent tree growth from interfering with lines. It proposes documenting any tree trimming and compensating by planting two new saplings for every tree affected to help conserve the environment.

2. Why trees or it’s
branches are cut by us?
 Safety of the public is paramount to us Godrejites.
 Trees in contact with power lines are a safety hazard, with
the potential for causing injury or even death by
electrocution if someone touches a tree made ‘live’ by a
power line.
 Trees in windy or stormy conditions can cause power
cuts. Power supply may be disrupted when trees or
branches break thereby damaging poles, power lines or
other structures.

3. Continued…
 Similarly, when conditions are dry, trees near power lines
can cause serious fires.
 These are the danger of trees near power lines.

4. Growth Limit Zone:
 The tree in this illustration will
need to be cut or trimmed
because it encroaches the
Growth Limit Zone.
 The Growth Limit Zone (GLZ) is
the minimum space
surrounding any powerline that
must be kept clear of trees and
other vegetation. The size of
this zone depends on the
voltage of the power lines.

5. The Notice Zone:
 The Notice Zone (NOTZ) extends one metre beyond the
Growth Limit Zone. Should a tree encroach the Notice
Zone, we may send a 'Hazard Warning Notice' advising
you that the tree must not encroach the GLZ.
 For Powerline spans up to 150 meters
VOLTAGE GROWTH LIMIT ZONE
Distance from any point on the lines or
equipment
33 kV 2.5 m
11 kV 1.6 m
0.433 kV 0.5 m

9. Problems caused by cutting
or trimming trees:
 Adverse impact on:
1. Atmosphere
2. Biodiversity
3. Economical impact, etc.
Most pressure will come from the world's developing
countries, which have the fastest-growing populations
and most rapid economic (industrial) growth.

10. Why this Kaizen?
 In our work, while erecting poles, sometimes it is seen
that a tree or it’s branch come in the way of our erection
activity.
 After taking all the requisite permissions, the tree or it’s
branches are trimmed off so that the line is laid and the
work is carried forward without any difficulties or
hindrances.
 Hence, we see that cutting or trimming of trees in
INEVITABLE. Therefore we have come out with this kaizen.

11. What can be done?
 All such events where we are required to cut or trim the
trees are to be noted by the site engineer in charge.
 Proper documentation of such activities should be done.
 For every tree affected (be it’s branch or the tree as a
whole), idea is to plant at least two saplings that would
not only serve as a compensation but also work as an
initiative towards the conservation of our mother nature.

12. Excel sheet for Documentation:

13. Tree plantation & Godrej :
 In face of ever increasing urbanization, Godrej has always
been alive to environmental concerns.
 It is our intention to give back as much, if not more, as is
being taken through the rigorous development process.
 At our Godrej, environmental consciousness is all pervasive.
So such initiative is only going to add to our CSR activity in
environmental preservation.
 Godrej strongly believes that green environment enhances
productivity and quality.
 So, continuing this noble ideology of our company, We, the
site engineers, too, can contribute.

14. After effects of Kaizen:
 After proper documentation of tree trimming activities at
site, the tree plantation can be done on quarterly basis.
 Plantation of saplings can be done along the roads, empty
places in the Jabalpur city area taking care that the
saplings would get ample amount of water, sunlight.
 The whole concept is to ensure that the situation is
improved upon from it's condition prior to trimming trees
hence maintaining the ecological balance.
