Mr.
chair
members
of
the
committee
Mike
Kennedy
and
the
director
of
Transportation
maintenance
and
repair
for
Minneapolis
Public
Works
today
our
subject
is
to
report
on
the
findings
of
the
tree.
Failure
study
conducted
by
the
University
of
Minnesota
following
the
wind
storms
in
June
of
2013
with
me
today,
is
Gary
Johnson,
a
professor
at
the
University
of
Minnesota,
who
was
the
lead
investigator
on
the
report.
I
will
give
a
brief
introduction
here
and
then
Gary
will
come
up
and
present
the
report.
Findings
to
you,
then
I'll
follow
up
with
a
little
bit
of
discussion.
C
Brief
discussion
on
some
of
the
steps
that
Public
Works
has
been
taking.
Since
this
study
came
out
in
the
last
year.
Also,
we
have
Ralph
sievert,
the
chief
Forester
from
Minneapolis
Park
and
Rec
board
here
to
answer
any
questions
that
you
might
have
and
his
team,
as
well
so
on
jun,
21,
2013,
severe
wind
storms
that
began
west
of
the
Twin
Cities
moved
eastward
into
Minneapolis
in
the
early
evening.
Private
and
public
Boulevard
tree
damage
caused
by
the
storm
was
quite
extensive.
C
Damage
trees
interrupted
above
ground
electrical
services,
many
streets,
sidewalks
and
alleys
were
blocked
for
several
days.
Anecdotal
evidence
suggested
a
higher
than
normal
frequency
of
total
tree
failures
involving
Boulevard
trees
in
Minneapolis.
These
tree
failure
incidents
called
wind
throws
and
forestry
terminology
are
where
trees
are
uprooted
or
partially
tipped
observations
suggested.
C
The
investigation
sought
to
determine
that
what,
if
any,
pre-existing
factors
may
have
contributed
to
the
rate
of
tree
failures
during
this
wind
loading
event,
funding
for
the
study
came
from
the
Minneapolis
Park
and
Recreation
Board
and
the
Mississippi
watershed
management
organization
with
that
I'll
bring
up
Garry
Johnson
and
he
can
go
through
the
his
report.
For
you.
D
Mr.
chair
council
members,
thank
you
good
morning
right
and
I'm
going
to
do
my
best
make
this
interesting
free.
All
the
the
opportunity
to
study.
Something
like
this
is
is
pretty
rare
and
unpredictable.
Most
research
studies
we
can
set
up,
observe,
collect
data
analyze.
This
is
we
wait,
wait
for
storms
to
hit
and
because
of
that,
there's
actually
a
dearth
of
information
on
the
type
of
storm
damage
that
we're
going
to
discuss
this
morning
because
of
this
waiting,
not
knowing
when
the
storms
going
to
strike.
D
So
this,
in
particular,
was
from
as
Mike
stated
2013
that
storm
one
of
the
storms
had
hit
Minnesota
that
summer
and
I'd
like
to
start
off
with
trees
and
winds
collide
everywhere.
The
the
kind
of
flip
it
reacts
you
get
from
some
people
is
like
well.
The
reason
why
trees
go
down
is
because,
when,
in
my
equally
flippant
responses,
then
why
don't
all
trees
go
down?
If
it's
wind,
then
everything
should
go
down.
Is
that
strictly
yet?
D
And
this
study
gave
us
a
rare
opportunity
to
look
at
this
typical
scene,
so
I
understand
why
people
would
say
well
it's
because
of
the
wind.
But
if
you
look
at
this
scene
by
the
way
which
was
in
Minneapolis,
it
looks
pretty
destructive
but
they're
only
two
trees
down
there
only
two
trees
damaged-
and
this
is
fairly
typical
for
storms,
it's
the
weaklings
or
the
ones.
You
know
if
we
have
a
catastrophic
wind
event
like
a
tornado
or
nothing
survives
silos.
D
Buildings
don't
survive,
but
in
these
in
these
regular
storms
that
are
becoming
even
more
regular
watching
the
state
climatologist
that,
where
we're
up
by
thirty-seven
percent
in
these
high
volume,
rain
events
and
wind
events
over
the
last
three
decades,
so
I
think
that
was
kind
of
the.
The
critical
reason
for
the
study
is,
then,
why
don't
all
trees
fail?
D
And
if
you
look
at
a
storm
failure
triangle,
there
are
three
elements
to
look
at
or
two
to
analyze
in
an
event
like
this
one
is
the
loading
then
itself
and
we're
going
to
focus
on
a
wind
loading
event.
Second,
is
the
site
characteristics
and
we're
focusing
on
boulevards,
and
then
third
is
the
tree
variable
and
we
looked
at
a
lot
of
different
variables
with
the
trees,
including
the
size,
etc.
So
with
wind
loading
events,
I
think
what
the
general
public
doesn't
understand
is
that
a
thunderstorm
can
be
more
outrageous
than
an
ef-0
tornado.
D
It
has
higher
wind
velocity,
so
I
think
there's
almost
a
sense
of
complacency
as
I.
Don't
worry
it's
just
a
thunderstorm
coming
along,
but
thunderstorms
can
be
clocked
at
80
miles
per
hour
and
that's
what
hit
Minneapolis
that
day,
that
you
know
didn't
didn't
even
reach
70
miles
per
hour,
so
it's
in
that
category,
but
that
is
still
more
powerful
than
any
f0
tornado.
So
these
wind
loading
events
are
unpredictable
and
and
they
can
cause
a
lot
of
damage
the
site
characteristics.
D
The
degree
of
friction,
which
is
just
a
fancy
word
for,
is
there
anything
the
slow,
the
wind
down
buildings,
other
trees,
topography,
etc,
a
limited
root
plate.
This
is
why
we
focused
on
boulevards
in
particular,
because
that's
a
good
example
of
a
limited
amount
of
space
that
roots
can
actually
grow
in.
So
they
don't
have
normal
route
plates
and
normal
distribution
routes
to
keep
them
vertical,
etc,
etc,
etc.
So
we'll
go
over
those
site
characteristics
and
then
the
tree
itself.
Now
the
trees
are
all
different.
D
They're,
dynamic
systems,
they're
a
dynamic
system,
basically
perched
on
a
static
infrastructure.
The
streets,
don't
change
the
soils
pretty
much
same,
it's
the
tree
that
is
so
dynamic.
And
then,
if
you
look
at
the
variables
you
know
it's
intuitive,
how
big
is
it
how
much
wind
sail?
Does
it
have
etcetera
any
any
structural
weaknesses
and
that's
how
we
analyze
and
we've
been
when
I
say
we
it's
collectively,
this
team
I've
been
working
with
since
1994.
D
We
were
kind
of
directed
at
that
point
by
the
state
tree
board
to
investigate
why
trees
fail
and
storms
and,
quite
honestly,
there's
a
lot
of
information
on
why
trees
fail
above
the
ground
when
they
break
at
stems
or
branches
break
off
very
very
little
information
when
there's
total
tree
fail
year.
So,
as
you
look
at
the
data
in
here,
the
storms
that
data-
and
there
were
two
of
them-
were
worse
in
western
Minnesota
and
Hutchinson,
etc.
D
Then
they
were
here,
but
they
still
caused
a
considerable
amount
of
damage,
and
if
you
were
one
of
the
unlucky
people
that
lost
your
power
that
day,
there
are
a
lot
of
people,
the
the
losses
in
terms
of
electrical
service
and
repair,
etc.
It's
just
amazing
for
a
storm
like
this
to
relatively
tolerable
wind
storms
that
came
along
that
cause
that
much
damage
well,
as
Mike
said,
we
were
already
collecting
data
at
this
point
in
other
communities
during
the
storm.
D
Quite
honestly,
and
one
of
the
things
that
we
were
noticing
is
like
there
is
seem
to
be
an
extraordinary
lean
toward
the
number
of
trees
going
down
in
boulevards,
as
opposed
to
lawns
and
parks,
etc.
And
the
other
thing
we
noticed
that
seemed
to
be
associated
with
some
fresh
sidewalk
repair
and
fresh
is
this
kind
of
relative
thing,
but
you
could
tell
it
was
relatively
fresh
because
the
color
of
the
concrete
was
so
much
brighter,
it's
kind
of
anecdotal.
Well.
We
then
had
this
opportunity
to
study
this
in
much
more
detail.
D
Things
to
the
park
board
to
the
watershed
district
to
to
the
University
to,
and
one
of
the
things
that
I
wanted
to
be
very
conscientious
about-
is
to
remain
as
unbiased
as
possible
on
this,
so
I
contracted
with
the
university
of
minnesota
statistics
department
to
design
the
study.
So
I
told
him
what
we
wanted
to
study
they
laid
out
the
study
completely
and
that
we
followed
their
directives
turn
the
data
over
to
them.
They
analyzed
it
and
that's
a
results
of
the
study
today,
also
to
remove
as
much
bias
as
possible.
D
Collectively
there
are
probably
15
people
trained
by
us
that
we're
collecting
data,
so
it
was
not
one
person
going
out
because
there
is
that
danger.
You
start
seeing
what
you
want
to
see
and
when
you
have
the
conscious
conscientiousness
of
15
people
out
there
you
kind
of
get
caught.
If
you
start,
you
know
showing
any
bias
whatsoever,
so
we
did
everything
we
could,
because
this
is
such
a
unique
study.
There's
only
been
one
study
in
the
world.
D
That's
published
that's
similar
to
this,
and
that
was
in
Australia
and
as
you're
going
to
see
with
this,
we
ended
up
studying
a
total
of
I
think
it
was
3076
trees.
We
looked
at
every
single
tree
in
the
boulevards
in
the
path
of
the
storm
and
as
long
as
that
block
street
segments
have
at
least
more
than
one
tree
that
went
down.
We
studied
every
single
tree
there
and
that's
what
made
this
sword
unique
and
so
robust
excuse
me
there
were
a
total
of
three
hundred.
D
What
is
it
sixty
seven
trees
that
were
tipped
in
that?
So
again
we
look
back
at
why
don't
all
trees
too?
There
were
three
thousand
seventy
three
trees
white
and
only
three
hundred
sixty
seven
trees
too,
and
that's
really
what
piques
your
curiosity
there's
got
to
be
a
weak
link
in
there,
an
Achilles
heel,
so
I'm
sure
you
all
remember
the
path
of
the
storm
and
it
essentially
went
from
the
northwest
corner
to
the
southeast
corner
of
Minneapolis
and
it
hit
Richfield,
st.
Paul,
etc.
D
And
so
this
is
where
we
focused
a
study
and
in
particular,
when
we
talked
about
tipped
trees.
There
are
two
categories
of
tipped:
one
is
that
the
stump
tipped
greater
than
fifty
percent
of
the
roots
out
of
ground
and
the
other
one
was
less
than
fifty
percent.
Quite
honestly,
they're
they're
both
gone.
D
You
don't
leave
partially
tip
trees,
but
this
this
is
kind
of
a
technical
term
used
to
evaluate
tree
losses,
and
that's
why
we
use
this
to
be
consistent
with
federal
terminology
on
this
excuse
me,
so
the
black
street
segments,
then
we're
defined
as
a
typical
block
length
the
street
or
the
trees
on
both
sides
of
the
street
in
the
boulevard
and
I.
Think
I
have
a
graphic
here
yeah.
This
would
explain
it
a
little
bit
better.
D
So
when
you
look
down
this
typical
block
street,
we
looked
at
the
boulevard
trees
on
both
sides
and
what
we
are
trying
to
do
to
keep
this
as
unbiased
as
possible.
As
we,
we
literally
went
with
black
street
segments
that
were
running
north-south,
so
we
would
kind
of
avoid
the
impact
Valley
sir
blunt
force,
winds,
etc
just
to
try
to
even
this
out
as
much
as
possible,
and
we
still
came
up
with
over
3,000
trees.
D
These
are
the
variables
we
studied
on
this
and
I
learned
a
long
long
time
ago,
not
to
second-guess
or
predict
what
variables
going
to
end
up
being
influential
or
important
in
the
ends.
We
just
collect
as
much
information
as
we
can.
The
information
collected
started
in
August.
It
was
completed
in
March,
so
it's
kind
of
a
if
you're
thinking
wasn't
there
a
lot
of
snow
inside
box
yeah
there
were
a
lot
of.
There
was
a
lot
of
shoveling.
D
What
we
were
particularly
interested
in
is
documenting
a
sidewalk
replacement
or
curbed
replacement
and
sidewalk
also
included
the
carriage
path
to
so
had
they
been
replaced
repaired
within
the
last
five
years.
Why
did
I
pick
five
years
completely
arbitrary,
completely
and
in
retrospect
and
clap
that
I
did
because
it
took
so
long
to
get
all
this
information?
It
was
an
onerous
task
and
if
you
look
at
the
lower
right
photo
in
some
cases,
there
was
actually
driveway
pad
replacements
in
there
too,
and
then
the
measurements
from
the
replacement
to
the
root
plate.
D
Most
of
the
time
I'd
say
at
least
half
the
time.
We
were
lucky
enough
to
find
the
date
stamped
in
the
concrete,
so
we
do
when
it
was
poor
to
replace
but
the
other
half
the
time
we
didn't,
and
so
we
spend
a
lot
of
time
and
the
archives
in
minneapolis
and
and
thanks
to
all
the
different
in
the
end,
you'll
see
the
the
thank
you
list
all
the
people
that
were
kind
enough
to
help
us
go
through
these
files
to
find
this
exact
data.
D
When
was
the
concrete,
when
was
the
sidewalk
repaired
without
that
I
wouldn't
be
here
today?
I
would
not
feel
comfortable
enough
today
to
give
you
the
information
that
we
had
so
and
we
also
recorded
if
there
was
any
damage
subsequent
to
the
three
failure
to
the
sidewalks
occurrence,
because
I'm
also
infra,
you
know
interested
in
how
much
does
it
cost
a
community
when
the
tree
leans
or
partially
leans
too?
So
this
data
was
collected,
etc,
and
sometimes
it
was
bad
most
time
that
big
of
a
deal.
D
So,
as
you
probably
know
by
now,
the
major
finding
was
having
the
sidewalks
replaced
was.
Was
the
Achilles
heel
for
these
tips?
This
was
the
most
critical
thing
and
it
it
if
you
looked
at
a
tree
that
was
not
near
a
sidewalk
pad
replacement
versus
one
that
was.
There
was
a
two
point,
two
four
times
greater
chance:
greater
risk
of
failure
for
the
one
near
the
sidewalk
replacement,
and,
if
you
think
about
this,
it
makes
sense.
D
Why
was
that
Sidewalk
pad
replaced
because
the
tree's
roots
or
the
trunk
of
the
tree
had
lifted
it
and
caused
a
trip
hazard,
something
unacceptable?
So
the
sidewalk
concrete
was
removed,
the
tree
roots
were
cut,
a
new
sidewalk
pad
was
replaced,
and
within
five
years
we
had
this
wind
storm
that
caused
this
type
of
damage.
So
you
know
it
did
make
sense.
D
One
of
the
things
that
we
did
find
out,
that
was
that
curb
replacement
did
not
have
a
significant
impact,
so
it
was
really
a
sidewalk
pad
replacement.
We
also
look
for
areas
where
there
had
been
complete
reconstructions
in
water
lines.
New
sidewalks
electric
lines,
whole
new
streets,
nothing
significant!
So
it
was
these
individual
repair
jobs
that
really
caused
the
this
weakness
in
here
and
more
than
doubled
the
chance
that
trees
would
fail.
D
So
we
would
have
situations
like
this,
where
the
concrete
pads
had
been
replaced
within
the
last
five
years
because
of
the
damage
that
the
tree
roots
had
caused
on
this
now,
looking
at
space
and
species
and
again
this
is
intuitive
and
if
you're
sitting
there
thinking
like
good
grief,
does
this
man
get
paid
to
do
this
kind
of
intuitive
stuff?
Well,
that's
the
only
time
when
intuitive
things
really
start
becoming.
D
So
that
double
chance
to
so
we
had
this
this
list
of
species
there
were
over
30
different
tree
species
in
the
study,
but
there
are
only
about
four
or
five
of
them.
That
really
showed
the
weakness
and
what
did
they
have
in
common
they're,
big
and
so
an
ash
tree
when
it's
mature
as
a
big
tree
in
ash
tree
when
it's
been
planted
when
in
the
last
five
years
as
a
small
tree,
and
so
it
was
actually
what
was
the
category
of
tree
large
tree
category
ash?
D
What
was
this
actual
age
big,
so
smaller
trees,
no
big
deal
big
trees,
big
deal,
so
now
we
have
the
data
to
support
that
and
so
little
leaf
Linden's
and
if
you're
familiar
with
this
tree,
they
literally
have
the
wind
resistance
of
a
brick
wall.
If
a
blue
spruce
could
become
deciduous,
it
would
be
a
little
leaf
linden,
and
so
they
catch
a
lot
more
wind
than
the
average
treated
does
and
they're
big
too,
and
then
green
ash
borer,
green
ass,
just
gets
hammered,
left
and
right,
maples
and
Elms.
D
Now,
if
you're
thinking
well,
this
makes
sense
because
maybe
little
leaf
linens
are
the
most
common
tree.
They're
not
do
not.
Maples
are
the
most
common
ash
and
then
you
start
going
down
to
the
others.
So
it's
not
the
most
commonly
planted
tree
and
then
dbh
that
DB
h
is
in
measurement
of
the
trunk
diameter
at
four
and
a
half
feet
above
ground.
So
that
goes
back
to
what
I
was
saying,
that
these
are
not
only
large
tree
category
trees
but
they're
actually
mature,
and
they
actually
are
big
at
that
point.
D
Instead
of
a
new
12-foot
tall,
green
ash
being
planted,
these
are
mature
trees.
So
dbh,
then,
was
significant
again
when
sidewalk
repair
had
been
done
and
then
Boulevard
with
Boulevard
width
was
significantly
related
to
it,
but
again
only
when
the
sidewalk
repair
was
done.
So
as
you
go
through
this
data,
you
see
that
common
thread,
which
is
sidewalk
replacement,
and
it's
not
that
concrete,
is
bad.
It's
just.
Why
is
the
concrete
being
replaced
because
the
tree
roots
or
the
tree
trunk
could
come
in
conflict?
D
D
Oddly
of
all,
this
research,
that's
a
one
piece
of
research.
It
has
about
four
decades
of
previous
research
behind
it,
and
this
was
University
of
Wisconsin
and
first
published
it
in
university.
Illinois
that
boulevards
less
than
10
feet
wide
are
more
at
risk
for
construction
damage,
declined
to
construct
an
image
and
then
failure
in
wind
storms
too.
D
So
a
little
bit
of
previous
research
backing
that
up
so
Boulevard
with
yes,
but
only
when
the
sidewalks
were
repaired
I
you
may
be
able
to
breathe
a
collective
sigh
of
relief
on
the
soil
properties
because
none
of
them
were
significant.
So
that's
one
thing
you
don't
have
to
worry
about.
The
bad
part
is
I
spent
a
ton
of
money
on
these
lab
tests.
D
Soil
tests
are
extremely
expensive
and,
in
the
end,
to
find
out
that
and
no
nothing
mattered,
except
soil
compaction
at
six
inch
depth
and
really
the
only
time
again
that
it
made
a
huge
difference
was
and
the
sidewalks
had
been
replaced.
So
we
keep
going
back
to
that
point,
which
kind
of
makes
it
easier
for
the
take
home
recommendations.
You
know
cutting
roots
jeopardizes
stability
whenever
possible,
consult
with
forces.
This
is
what
we're
trying
to
do.
D
D
Wider
is
better
at
least
for
boulevards
whenever
you
can
and
then
larger
trees
need
larger,
boulevards
or
larger
root
plates,
and
there
are
ways
of
playing
around
with
it
a
little
bit
to
accommodate
that,
so
an
acknowledgement
of
the
funding
which
you've
seen
it
and,
more
importantly,
an
acknowledgement
of
all
the
partners,
the
people
that
were
part
of
this.
This
is
a
very
unique
study
with
a
lot
of
partners,
a
lot
of
people
looking
at
each
other
scratching
their
heads.
Why
are
you
here?
What
are
you?
What
are
you
looking
for?
D
And
you
know
throughout
the
process?
It's
like
I,
don't
know
what
I'm
finding
I
don't
even
know
for
sure
when
I'm
looking
for
that's,
why
I'm
looking
at
everything,
but
in
the
end
it
was
a
outstanding
study.
I
do
want
to
mention
as
a
side
note.
I've
proved
that
or
presented
this
research
to
conferences
in
the
last
12
months
from
Utah
to
Massachusetts,
so
nothing
west
of
you
talk
I,
don't
know
why
they
haven't
invited
me,
but
this
has
helped
a
lot
of
communities
most
recently
last
week
in
Omaha.
D
E
Thank
you
very
much
and
I
really
appreciate
this.
This
report,
lots
of
trees
in
my
part
of
the
city,
went
down
because
of
the
storm,
and
people
were
wondering
and
curious
about
this
I
have
one
question
in
terms
of
the
sidewalk
replacement:
did
you
do
any
kind
of
inspection
of
the
tree
roots
to
see
if
they've
been
ground
or
cut
off
or
or
were
used
to
suming,
they
must
have
been.
D
D
Think
one
of
the
unusual
things
that
you
find
out
about
this
kind
of
study
is
you
can't
predict
how
roots
regenerate
or
how
fast
they're
going
to
regenerate
and
and
so
that's
why
we
photo
document
everything
and
we
have
it
up
next
to
a
screen.
So
we
know
this
scale.
You
know
it's
like
a
grid
board,
so
we
can
understand
scale.
We
can
see
the
severed
roots,
etc.
So,
in
answer
your
question-
yes,
they
had
been
cut
was
documented,
every
single
one
of
them,
Thanks.
E
D
And
I
think
that
it
also
emphasizes
again
these
little
insidious
things
that
happen.
You
know
grinding
and
cutting
roots
sounds
so
dramatic,
putting
in
a
cable,
TV,
cable
gas
line
or
something
just
cutting
a
forge.
It
doesn't
matter
if
you
go
in
with
a
backhoe
or
if
you
go
in
with
a
scalpel.
If
you
cut
the
root
to
the
trees,
cut
the
roots
of
the
tree,
it's
less
stable,
so
I
think.
With
this
study
it
seemed
a
little
bit
more
gross,
but
it's
no
different
than
the
other
activities
that
reduce
the
stability
of
a
tree.
D
F
Thanks
mr.
chair,
well
Wow
what
I
have
to
say,
this
was
a
really
really
striking
report.
I,
don't
know
that
it's
just
the
the
significance
of
the
sidewalk
work
as
compared
to
being
more
significant,
the
boulevard
width
and
some
other
elements.
If
I'm
reading
that
right
right,
because
I
think
there
was
a
lot
of
speculation
as
we
went
through
the
aftermath
of
the
storm
about
how
the
boulevard
width,
how
significant
that
was
compared
it
to
other
elements,
it
I,
you
know,
and
so
this
report
wasn't
planned
to
have
comments
by
city
staff.
F
So
I
don't
know
if
mr.
Kennedy
or
miss
Hamilton
have
thought
through
kind
of
what
their
recommendations
are,
but
it
seems
to
me
just
refining
through
your
study,
what
was
the
cause
of
so
many
trees
really
gives
us
a
good
ability
to
maybe
think
different
differently
about
our
practices
and
how
they
can
affect
tree
strength
into
the
future.
The
other
thing
I
was
thinking
about
is
we
are
the
city
is
not
the
only
entity
that
works
in
the
boulevard
or
does
work
on
the
sidewalks.
F
So
often
we
have
entities
and
I'm
thinking
of
it
a
particular
example,
but
this
is
not
the
only
entity
that
works
in
that
space
is
centered.
Centrepointe
was
doing
some
required
work
on
the
gas
lines
and
we
actually
had
some
complaints
from
neighbors
who
saw
how
they
were
cutting
tree
roots,
and
then
we
did
some
work
together
with
staff
to
work
on
recommendations
for
how
they
could
have
a
lesser
impact.
But
it
seems
to
me
this
is
a.
F
B
Mr.
chair
and
member
glidden
mike
kennedy
is
in
fact
prepared
to
step
up
and
share
with
you.
We
took
the
the
results
of
this
study
very
seriously.
Obviously,
a
lot
of
interesting
things,
and
so
mike
has
been
working
internally
with
Public
Works
staff,
as
well
as
the
park
board
to
figure
out.
What
can
we
do
and
how
can
we
utilize
these
results
so
when
you're
ready,
he
can
certainly
step
up
and
share
that
information
with
you.
D
If
I
may
say
one
more
thing,
mr.
chair
and
councilmembers
trained
as
a
scientist,
I'm
trained,
not
to
believe
one
thing.
Actually,
that's
my
human
nature,
I
pretty
much
doubt
everything.
That's
ever
said
to
me,
but
I'm
trained,
also
not
to
believe
solely
in
one
research
study
or
even
solely
in
to
research.
Studies
are
three:
when
you
start
getting
an
accumulated
body
of
evidence,
then
you
become
more
comfortable.
D
That's
the
first
thing
and
one
of
the
this
sounds
terrible,
but
one
of
the
things
that
has
resulted
from
this
as
I
have
a
memorandum
of
understanding
the
st.
cloud
with
a
number
of
cities
in
the
state
that,
when,
if
storms
come
this
year
next
year
next,
following
year,
we
can
duplicate
the
study
in
that
community.
We
have
permission
to
do
that.
D
The
more
evidence
like
this
that
we
can
collect
then
the
more
comfortable
we
can
be
with
it,
so
that
that's
the
first
thing
is
like
this
is
a
really
good
study,
very,
very
good
evidence
from
it.
But
it's
one
study
here
and
just
keep
that
in
perspective.
The
second
thing
is,
it's
very
easy
to
find
faults
very
difficult
to
find
solutions
sometimes,
and
most
of
the
solutions
associated
with
this
are
not
solutions
that
can
happen
tomorrow.
D
A
G
D
You're
perfect
tree
is
a
tree
that
gives
you
canopy
I,
don't
I,
don't
know
if
anybody
has
sits
in
the
shade
of
a
tree.
Trunk
I,
don't
know
of
any
tree
trunk
that
helps
you
know
moderate
or
slow
down
rainfall,
so
it
doesn't
all
end
up
in
the
storm
water
system
and
that
its
canopy
canopy
canopy.
So
your
your
perfect
tree
is
a
large
tree
with
a
large
canopy.
The
trick
is
finding
the
perfect
space
for
it.
D
Okay,
that's
the
trick
and-
or
you
know,
substituting
sidewalk
paths
of
perhaps
they'll
be
a
redesign
of
the
architecture
of
sidewalks,
where
sidewalks
in
certain
areas
start
at
the
curb
line,
rather
than
leave
for
six
or
eight
foot
wide
Boulevard,
and
this
has
largely
been
the
path
of
Duluth.
They
have
gone
to
when
they've
reconstructed
a
lot
of
their
there
they've
eliminated
boulevards.
Basically,
they
start
the
sidewalk
at
the
curb
and
they
use
the
right-of-way
area
for
planting
trees.
That's
just
one
alternative,
so
that's
my
long-winded
way
of
saying.
No.
G
G
A
H
You
mr.
chair
I,
think
council
vice-president
Glen.
It
mostly
kind
of
answered
my
question
and
gave
that
comment,
but
I'm
curious
part
of
your
presentation
talked
about
there
was
there.
What
do
you
suspect
could
be
the
difference
with
curb
replacement
versus
sidewalk
replacement
and
I
think
this
might
get
more
into
our
public
work.
H
Staffs
I
know
there's
a
different
process
for
those
things,
but
it
occurs
to
me
that
they're,
mostly
equidistant
from
from
each
and
like
you
said
when
you
make
a
cut,
doesn't
matter
if
you're
going
in
with
a
backhoe
or
or
ask
Apple
in
terms
of
what
you're
removing
but
I.
Just
wonder.
You
know
what
kinds
of
things
do
we
do
with
curb
replacement
versus
sidewalk
that
makes
sidewalk
work
more
precarious
for
the
urban
canopy.
H
D
Chair
councilmember,
Palmisano
I
think
in
this
case
it
was
probably
more
of
a
situation
of
there
were
so
few
curb
replacements
done
within
the
last
five
years
in
the
path
of
the
storm,
but
I
go
back
to
since
I've
been
working
on
this
since
1994
working
a
lot
of
communities
and,
generally
speaking,
it's
the
different
between
routes,
running
parallel
to
the
activity
versus
perpendicular.
So
with
sidewalk
replacements,
the
roots
are
running
perpendicular
to
the
sidewalk
their
severed,
so
the
sidewalk
can
be
replaced
with
with
curbs
roots
hip
curbs.
Rarely
do
they
ever
go
under.
D
Mellow
they
hit
a
curb,
and
rather
than
confront
it,
they
just
follow
the
path
of
the
curb.
So
unless
you're
asked
Philly
widening
the
street
most
of
the
time
the
curb
is
removed
and
a
new
curb
is
put
in
and
very
little
damage
is
done
to
those
roots
that
are
almost
stacked
up
to
the
interior,
the
curb
because
they're
running
parallel.
D
A
Thank
you
turn
in
this
study,
obviously
very
comprehensive
and
to
your
earlier
point,
not
only
is
it
interesting,
it's
also
very
edifying
as
well,
but
definitely
interesting
and
I
think
the
effort
and
the
expenses
that
you
you
highlighted.
We
want
to
invest
in
knowing
how
to
best
manage.
We
want
to
have
a
data-driven
approach,
and
so
this
work
is
very
impressive
indeed
and
clearly
unique
coming.
A
This
is
just
completely
anecdotal,
but
there's
a
row
of
hack
berries
of
several
blocks
in
my
where
I
live
and
they
full
canopy
they've
been
around
for
a
long
time
and
not
one
is
dropped.
Is
there
some
kind
of
root
pattern
that
they
just
adapt
better
to
urban
conditions,
or
is
that
a
variable
that
would
need
to
be
explored
more
vertically
in
another
study?
Mr.
D
Chair,
that
is
that's
a
really
good
question
and
it
also
points
out
the
dynamic
situation.
These
trees
are
grown
if
there
is,
if
the
soil
is
not
a
compacted
soil
compacted
to
the
point
where
roots
can't
penetrate
hackberry
roots
do
go
deeper,
so
they
would
be
more
stable
because
they
would
be
less
dependent
upon
those
roots
right
near
the
surface.
So
yes,
what's
interesting
about
hacker?
Oh
it's!
You
know
I'm
a
tree
gig.
D
So,
what's
interesting
to
me
about
hack,
berries
is
when
hack
berries
cause
damage
to
sidewalks
its
most
time,
it's
not
from
their
roots.
It's
from
the
trunk
flare.
So
at
the
base
of
the
tree,
where
it
spreads
out
there
and
if
they're
in
very
narrow,
Boulevard
errs
or
planned
a
too
close
to
pavement,
they
will
damage
the
concrete,
but
it's
not
from
the
roots.
It's
from
the
base
of
the
trunk,
where
it
tapers
out
which
gives
the
tree
stability.
So
there
there
are
some
unusual
growth
habits
with
hackberry
yeah.
D
It's
kind
of
this
randomness
of
the
soil
in
the
city
too,
because
we
we've
studied
some
soils
where
you
know:
I'm
185
pounds
and
I
have
to
jump
up
and
down
on
the
probe
just
to
get
it
through
the
soil
and
then
we'll
go
a
block
later
as
beautiful
sandy
long
and
it's
completely
completely
unpredictable
and
I.
Think
that's
why
it
seems
that
the
trees
are
unpredictable
too.
A
Thank
you.
I
think
there
were
some
queries
that
suggested
some
interface
with
other
staff
folk.
So
I
know
we
have
our
public
works
and,
of
course
we
have
our
our
jurisdictional
partners
who
do
most
of
the
care
of
the
trees,
and
so,
if
anyone
felt
appropriate
to
the
questions
that
have
arised
so
far.
Okay.
Thank
you.
Thank
you.
Thank.
C
You
very
much
Gary
that
was
very
interesting.
Let's
talk
a
little
bit
about
what
Public
Works
has
done
in
since
the
release
of
the
report
and
looking
at
it.
One
of
the
things
that
we
did
was
we
reviewed
the
2004
urban
forest
policy
that
was
commissioned
and
completed
back
in
two
thousand
four
collaboration
with
the
Memphis
tree.
Advisory
Committee,
the
public
works
in
forestry
to
look
at
design
conditions
in
considerations
for
the
urban
forest.
We
found
that
a
lot
of
the
things.
C
A
lot
of
the
recommendations
that
came
out
of
this
report
were
already
mentioned
there
and
are
sort
of
being
done,
and
in
fact
now,
Public,
Works
and
forestry
folks
are
getting
together
to
go
through
the
policy
and
update
it.
Based
on
the
findings
of
this
current
report
and
see,
if
there's
more,
that
we
can
do
and
in
an
update
it.
Like
I
said
there
were
a
lot
of
things
that
we
were
already
doing.
C
One
of
the
things
that
the
Minneapolis
tree
advisory
committee
recommended
was
a
creation
of
a
person,
a
staff
member
who
could
focus
on
these
issues
and
they
advocated
for
the
creation
of
a
forestry
preservation
coordinator,
an
FPC
on
behalf
of
the
park
board
that
could
be
specialize
in
working
with
us
and
any
other
parties
that
are
doing
construction
and
maintenance
work
in
around
the
trees.
To
help
prevent
that.
C
C
We
discussed
alternative
excavation
techniques
in
the
field
that
was
this
was
something
that
was
already
mentioned
in
the
2004
orbit
forest
policy,
but
there's
new
technology
and
new
things,
and
one
of
the
things
they
talked
about
was
I'm
using
some
technology
called
an
hydro
excavator,
which
is
much
less
invasive,
much
less
Demi
damaging
to
roots
and
will
aid
in
the
not
needing
to
sever
roots
and
be
able
to
install
utilities
underground,
with
minimal
effect
to
the
trees.
And
again
we
started
to
work
with
the
FPC
in
in
our
design
force.
C
There's
a
lot
of
recognitions
about
Boulevard
wits
and
things
like
that.
Whenever
there's
an
opportunity
to
do
that,
our
design
folks
will
be
in
looking
at
those
opportunities
to
get
wider
boulevards
plant,
the
appropriate
trees
and
we
can't
get
wider
boulevards
and
just
be
much
more
in
tune
with
with
the
process.
So
Public
Works
will
continue
to
collaborate
with
the
forestry
park
board
forestry
to
find
ways
to
minimize
the
effect
of
construction
and
maintenance
activities
and
increase
tree
resistance
to
storm
damage
from
wind
loading.
C
If
you
have
any
questions
about
trees
themselves
and
a
lot
of
the
park,
board's
processes
and
and
work
so
far,
Ralph
Seifert
is
here
to
answer
questions.
I
can
answer
any
questions
you
have.
Otherwise.
Our
recommendation
today
is
to
receive
and
file
this
report
and
and
we're
here
to
answer
any
questions.
A
Counseling
record
and
then
I
would
actually,
after
that,
whatever
queer
you
have
mr.
sievert,
if
you
could
just
come
up
an
approach,
we
always
look
to
to
the
park
and
rec
as
our
caretakers
of
the
trees
themselves
and
so
any
comments
or
insights,
/
/.
The
findings
would
be
helpful
for
today's
conversation,
if
you'd
be
willing
but
councilman
or
mr.
Seaver
wait,
wait.
Yeah.
I
Welcome
good
morning,
council
members
I
think
one
of
the
things
that
Mike
alluded
to
and
Gary
also
is
that,
in
addition
to
the
work
around
sidewalks,
there
are
a
lot
of,
let's
call
them
external
factors
that
affect
trees.
So,
in
addition
to
what
Public
Works
does
there's
things
that
centerpoint
energy
does
there's
things
that
Xcel
Energy
does
there's
things
that
our
own
park
board
playground
redevelopment
pads
all
those
sorts
of
things.
So
there's
many
different,
the
county,
the
state.
I
We
we
just
see
that
improving
and
we're
very
fortunate,
because
the
individual-
that's
in
this
position,
uniquely
came
to
us,
maybe
like
say
seven
years
ago,
but
he
previously
had
worked
for
the
city
of
milwaukee
and
was
very
intimately
involved
in
this
exact
same
work
with
the
person
in
Milwaukee
who
has
been
doing
it
for
decades.
So
he
was
kind
of
already
sort
of
well
trained
in
a
lot
of
the
work
that's
involved
in
in
preserving
trees
and
the
other
part
two
is
he's
already
been
able
to,
because
we
look.
I
We
also
look
at
the
idea
that,
if
you
can't
preserve
a
tree,
then
we
do
want
to
make
sure
we
get
the
tree
removed
before
the
tree
falls
and
I
think
that's
another
important
part
of
it
and
he's
been
able
to
make
that
determination
in
the
field.
In
some
cases
where,
based
on
the
situation,
you
know
there's
a
tree
that
might
have
to
be
sacrificed
in
order
for
the
safety
and
the
elimination
of
all
the
hazards
that
come
with
a
tree
falling.
I
A
A
It
seems
like
we
have
an
ongoing
process
here,
that
of
which
this
is
not
an
endpoint,
and
so
what,
in
terms
of
the
activities
that's
taking
place
with
both
the
jurisdictional
partners,
the
other
outside
utility
partners
and
and
of
course,
are
relevant
Commission's
being
both
the
pedestrian
realm,
as
well
as
the
treat
advisory,
and
so
what's
what's
the
outcome
after
we
do
the
receiving
file
and
what
ongoing
products
and
policy
directives
might
come
out
of
this
work
as
we
move
forward
in
time
lines?
Yes,.
B
Chairman
Reich
I
think
it
as
Mike
highlighted
he
and
his
team
are.
We
have
staff
who
are
frequently
engaged
with
Minneapolis
Park
part,
and
we
are
reviewing
our
policies
and
looking
at
how
we
can
do
this
work
better.
We
are
calling
the
forestry
coordinator
to
come
in
and
confer
with
us
in
the
field
and
on
our
plan
review
so
I
I
would
say
this
is
just
an
ongoing
relationship
where
we
are
trying
to
improve
our
practices
and
try
and
figure
out
how
we
can
cause
less
the
image
two
trees.
B
One
of
the
things
I
think
we
can
note,
is
there's
lots
of
trade-offs
here.
As
you
all
know,
there's
always
a
lot
of
debate
about
how
we
spend
every
foot
in
the
right
of
way
and
so
well.
An
eight-foot
Boulevard
is
ideal.
Absolutely
we
know
that
sometimes
that
wider
Boulevard
can
mean
we
can't
get
parking
or
we
can't
get
a
bike
lane
in
or
we
can't
get
other
things.
B
So
I
think
the
knowledge
base
is
something
we're
going
to
continue
to
try
and
spread
and
utilize
throughout
public
works,
and
it
comes
down
to
the
point
by
point
decision
we
make
on
in
whether
it's
in
the
field
or
in
a
particular
design.
So
I
really
see
this
as
ongoing
knowledge
that
Public
Works
is
going
to
continue
to
use
and
incorporate
it
into
our
practices.
E
E
The
the
the
report
made
me
go
in
and
look
at
our
urban
forestry
policy
and
look
at
that
and
there's
a
whole
section
about
avoiding
conflicts
between
trees
and
public,
sidewalks
or
right
of
ways
in
there
and
there's
one
point.
I
was
curious
if
we'd
ever
done,
there's
one
piece
in
there
that
says
public
works.
C
Good
question:
mr.
chair
customer
garden:
the
answer
is
yes,
absolutely
the
the
tool
that
we
use
are
called
tree
rings.
Essentially,
we
take
and
take
sort
of
cut
out
a
scallop
or
a
semicircle
out
of
the
sidewalk
with
maybe
reduce
the
width
by
a
foot
or
something
like
that.
Sometimes
we'll
do
it
immediately
when
replace
the
sidewalk
to
avoid
roots
that
have
come
up.
That
are
that
we
know
would
be
very
danger
to
cut
so
we'll
install
that
tree
ring
other
times.
C
What
we
will
do
is,
as
we
put
a
panel
in
next
to
a
tree,
that
there
may
be
some
expectation
that
in
the
near
future,
it
may
grow
enough
so
that
the
roots
would
start
to
impact
the
sidewalk.
If
you
score
that
ring
in
there,
you
can
go
out
later
and
knock
it
out
as
the
tree
grows
rather
than
having
to
replace
the
whole
panel.
C
E
Many
years
well,
I
think
tree
grates
rings
a
bell
with
everybody.
We
don't
see
a
lot
of
those
in
residential
areas
with
boulevards.
However,
then
there's
a
another
section
that
the
section
that
really
concerned
me
there's
a
through
under
that
it
says:
there's
a
section
about
no
tree
shall
be
removed
without
written
permission
from
Minneapolis
Park
and
Recreation
Board.
E
But
then
it
says
the
contract
remove
all
routes
within
an
area
defined
as
six
and
one-half
inches
below
the
top
of
the
new
finished
sidewalk
grade
by
severing
them
off
cleanly
with
the
sharp
ax
or
by
grinding
them
off
using
a
route
grinding
machine
instead
of
breaking
them
off
with
the
backhoe
or
similar
equipment,
and
that
just
calls
it
out
to
me.
We
then
said
part
of
our
policies
to
allow
them
to
cut
everything
away.
E
There's
actually
a
great
example
in
the
second
ward,
if
somebody
who
had
an
enormous
elm
tree
that
they'd
preserved
and
it
had
made
it
through,
and
so
we
worked
with
Public
Works
and
the
park
board.
We
went
out
there
and
they
actually
did
a
very
small
grade
up
on
the
sidewalk
so
that
we
would
they
didn't,
have
to
cut
and
grind
of
it,
and
it
was
fantastic
so
that
I,
don't
we
don't
have
to
discuss
that
piece
of
the
policy.
But
that's
the
part
that
Tennyson
Oh
finding
this
here
makes
me
think.
E
Committee.
No
later
than
July
thirty-first
2014
and
that's
an
arbitrary
date
that
I
just
thought
would
give
us
plenty
of
time.
But
if
there's
a
different,
if
it's
it,
that
doesn't
make
any
sense
you
can,
let
me
know,
but
I
think
that
might
give
us
some
time
to
develop
some
policy
recommendations.
Especially
if
you
have
to
change
this
policy
itself,
and
we
can.
We
can
hear
that
so.
A
Assistant
director
Hamilton,
since
the
work
is
already
identified
as
ongoing
and
happening,
and
all
the
parties
that
are
referenced
I
are
actually
already
engaged.
The
key
thing
is
actually
the
report
back
and
the
nature
of
the
report
back
said.
Is
it
your
notion
that
it
should
be
specific
to
the
ordinance
the.
E
I'm,
yes,
I'm
hopeful
they'll
have
some
recommendations
for
changes
actually
to
the
policy
I
mean
it
may
be
that
there's
more.
That
comes
back
to
so
we
can
be
open
about
that.
But
I
do
want
to
flag
that
we
could
potentially
flag
that
here.
But
when
I
say
changes
to
city
policy,
that's
the
document
I'm
referring
to.
Okay,.
A
B
Mr.
chair,
of
course
we
are
doing
this
work
already
sort
we're
happy
to
come
back
and
report
back
to
committee.
I.
Think
July
thirty-first
is
fine,
whether
we
would
be
I
imagine
some
of
these
conversations
could
could
be
more
prolonged
than
others,
because
there
are
some
different
perspectives
on
this
issue,
but
in
any
case,
I
think
it
would
be
fine
for
us
to
report
back
midsummer
on
where
we
are
in
terms
of
what
changes
we've
made
and
perhaps
what
questions
were
still
thinking
about
talking
about
discussing
and.
A
A
I
think
we
have
a
counselor
Gordon,
has
a
motion
for
a
staff
directive.
Any
further
discussion
on
that
point
see
none
all
in
favor,
say:
aye
aye,
aye,
dis,
empty
name
that
carries
again.
Thank
you.
Everyone
who's
been
involved
in
putting
this
day
together,
and
the
commitment
to
do
it,
I
think,
is
both
definitely
reflective
in
the
various
jurisdiction
and
departments.
How
important
you
take
this
asset,
but
here
it'll
always
be
an
interesting
topic
for
us
to
the
very
speak
you
know
meet
minneapolis
is
new.
Symbol
has
trees
when
you
fly
into
the
city
minneapolis.
A
The
most
impressive
thing
you
see
is
the
tree
canopy,
it's
stunning
and
so
and
of
course,
all
the
functionary
of
functional
things
that
it
does
in
terms
of
environmental
impacts
and
aesthetics,
etc.
It's
it's
it's
quite
a
package
of
how
important
it
is
and
its
benefits
are
very
layered,
so
we
did
very
much
look
forward
to
that
toward
and
knowing
that
this
will
be
an
ongoing
thing
in
terms
of
managing
our
assets.
So
thank
you
very
much
for
the
work
with
that.
We
have
conclude.
