E
C
Phenomenal,
thank
you
chloe.
We
will
go
ahead
and
get
started.
It
is
602
pm,
so
welcome
everyone.
Thank
you
for
being
in
attendance
this
evening.
This
is
a
the
second
for
the
day
meeting
of
the
city
of
charleston
city
plan
water
lab,
and
this
is
an
informational
session
where
you
are
going
to
hear
from
city
staff,
but
primarily
the
team
of
experts
who
we
have
hired
to
assist
us
to
analyze.
How
water
is
going
to
affect
is
currently
and
will
affect
the
city
of
charleston
as
we
work
on
our
comprehensive
plan.
C
F
C
First
of
all,
just
as
we
do
before
every
meeting
a
virtual
gathering
code
of
conduct.
First
of
all,
please
be
patient
with
each
other
and
with
the
technology.
Even
though
we're
seasoned
professionals,
things
do
go
wrong.
Occasionally,
all
everyone's
microphones
will
be
muted
for
the
duration
of
the
event,
and
that's
so
that
we
can.
We
can
hear
the
speakers
and
if
you
have
questions
which
we
hope
that
you
do,
please
use
the
chat
box
at
the
bottom
of
your
zoom
program
to
ask
those
questions.
C
We
will
look
at
those
and
then
we
will
have
our
team
members
answer
those
questions
by
the
themes
and
during
the
q
a
session,
and
I
would
also
just
remind
everyone-
this
is
being
broadcast,
live
on
youtube
and
I
believe
that
we're
being
recorded
looking
to
my
staff
to
verify
that.
I
think
that
I
think
that
we
are
yes,
we
are
as
of
right
now.
Thank
you,
chloe,
okay,
very
good,
so
we'll
go
to
our
next
slide.
C
C
C
So
what
is
the
charleston
city
plan?
This
plan
is
required
by
the
state
of
south
carolina.
Every
major
city
has
to
produce
a
comprehensive
plan.
That
plan
guides
the
physical
growth
of
the
city.
It
is
a
vision
plan
that
discusses
the
ways
that
the
city
will
change
over
time
and
it's
developed
by
the
planning
commission
and
it
is
adopted
by
our
elected
city
council,
and
it
is
also
revised
every
10
years,
and
this
is
one
of
those
years.
C
C
First
of
all,
it
makes
recommendations
about
the
future,
and
this
plan
uses
objective
information
and
analysis
to
help
make
those
recommendations.
That's
one
of
the
things
you'll
be
seeing
this
evening.
It
also
incorporates
input
from
everyone.
It's
our
job,
to
listen
to
all
people
in
the
city,
not
just
those
who
are
the
regulars
at
public
meetings,
but
also
folks
who
don't
normally
participate.
We're
really
trying
to
listen
to
everyone.
C
The
plan
also
informs
daily
decisions
by
the
city
of
charleston's
planning
staff
by
the
planning
commission
and
by
city
council.
When
we
look
at
changes
in
land
use.
So
it's
a
document
that
we
use
every
single
day
there's
a
few
things
the
plan
doesn't
do
it
does
not
by
itself
change
zoning
in
the
city
of
charleston.
It
makes
recommendations,
but
any
change
in
zoning
has
to
be
considered
individually
and
has
to
be
taken
up
by
our
planning,
commission
and
city
council.
C
It
does
not
change
stormwater
regulations,
it
is
not
about
how
individual
sites
are
regulated
at
the
at
the
technical
level.
That's
handled
by
a
completely
different
mechanism
and
the
handling
of
stormwater
on
individual
development
sites
is
a
separate
process
that
is
run
by
our
amazing
stormwater
department.
C
The
plan
does
not
change
taxation
in
the
city.
Nothing
about
your
taxes
will
change
as
a
result
of
this
plan.
It
is
about
land
use
and
growth
and
infrastructure,
but
it
does
not
change
anything
related
to
taxes,
and
the
last
thing
is
that
it
doesn't
make
detailed
policy
recommendations
that
are
already
covered
in
other
adopted
plans.
There
are
a
whole
constellation
of
other
documents
and
and
plans
that
guide
detailed
policy.
This
is
about
the
30
000
foot,
guiding
vision
for
our
city,
so
we'll
go
to
the
next
slide.
C
Thank
you.
Just
continuing
on
here,
very
briefly,
an
introduction.
This
plan,
the
charleston
city
plan
in
the
year
2020,
is
rooted
in
four
basic
guiding
principles.
Water
comes
first
we're
looking
at
where
it
is
and
where
it's
going
to
be,
that's
what
we'll
be
talking
about
this
evening.
The
second
thing
is
that
it's
data
smart
and
we
have
used
some
of
the
best
people
in
the
country
and
we
are
working
with
some
phenomenal
teams
to
gather
the
best
data
available
and
to
understand
the
challenges
facing
the
city
objectively.
C
We
are
asking
all
members
of
the
community
to
partner
in
the
planning
process,
not
just
to
give
their
input
but
to
help
guide
decisions
that
are
made
by
staff,
as
this
plan
is
being
created,
we'll
go
to
our
next
slide,
I'm
going
to
be
done
soon.
I
promise
you
the
city
plan,
as
are
all
comprehensive
plans
guided
by
10
key
elements.
These
are
set
forth
in
the
by
the
state
of
south
carolina.
It
looks
at
population,
economic
development,
natural
resources,
cultural
resources,
community
facilities.
C
These
are
things
like
public
services,
housing,
of
course,
land
use
transportation,
something
called
priority
investment.
The
comprehensive
plan
should
inform
the
city's
decisions
about
how
to
invest
money
in
infrastructure,
and
then
the
last
thing
which
we
are
willingly
adopting
is
is
resilience,
which
is
how
we,
as
a
city,
bounce
back
from
disasters
and
how
we
become
more
prepared
for
what
the
future
will
bring
us.
These
are
the
ten
key
elements
that
we
have
to
address
so
we'll
go
to
the
next
slide.
C
Okay,
almost
at
the
end
here,
if
you
look
at
this,
this
pinwheel
diagram,
starting
at
the
very
top,
the
first
phase,
which
is
what
we're
in
now
is
this
phase
in
the
kind
of
orange
color,
which
is
about
defining
existing
conditions
and
establishing
the
shared
vision
and
tonight
we're
going
to
be
talking
about
the
water
and
land
use
analysis,
defining
those
existing
and
future
conditions.
This
is
not
the
plan,
we're
not
at
the
point
where
we
are.
We
know
what
the
city
is
going
to
do.
C
C
Planning
for
water
is
our
reality
and
today
we're
going
to
do
a
deep
dive
into
the
preliminary
analysis
starting
number
one
with
water
and
land
use
we're
going
to
look
at.
Why
does
it
flood
where
what
kind
of
flooding
how
much?
And
how
will
this
change
with
the
climate?
This
is
a
key
question
for
us
to
answer.
C
C
We
are
working
with
our
team
from
the
dutch
dialogues
for
those
of
you
who
are
familiar
with
that.
We
had
some
of
the
foremost
experts
in
the
world.
Look
at
how
water
interacts
with
our
city
in
four
areas,
and
now
we
are
using
that
same
team,
along
with
our
dedicated
city
staff,
to
look
at
the
whole
city.
C
This
is
a
city-wide
analysis
and
it
is
a
massive
undertaking,
as
you
will
see
so
we'll
go
to
our
next
slide,
and
this
is
the
last
thing
that
I'll
say
and
then
I'll
turn
it
over
to
our
team,
because
that's
who
you
really
want
to
hear
from
so
we're
in
this
analysis
phase
and
the
question
in
everybody's
mind-
is-
will
be.
What
are
we
going
to
do?
We
are
a
city
that
is
surrounded
by
water
and
we
have
to
confront
our
future
with
water.
C
What
are
we
going
to
do
and
we
know
that
there
will
be
four
strategies.
There
are
areas
of
the
city
that
will
need
to
be
defended
from
water.
We
will
have
to
build
defense
systems,
barricades
that
protect
us
from
water.
There
are
places
in
the
city
where
we
can
adapt
to
water
where
buildings
and
infrastructure
can
be
elevated
and
it
can
be
flooded.
This
is
not
unlike
volley
beach
or
any
beach
community.
Today
they
are
adapted
to
to
higher
seas.
C
There
are
areas
that
we
will
need
to
reserve
for
sea
level
rise
where
there
should
be
no
new
construction,
because
those
places
should
be
reserved
to
help
us
live
with
water
and
then,
finally,
there
are
places
that
are
free
of
threat
from
rising
sea
levels
and
those
are
areas
where
we
should
grow,
so
this
strategy
has
not
been
figured
out
totally,
but
we
know
that
this
is
where
we
are
going
we're
going
to
have
to
view
the
city
through
this
lens
in
the
future.
As
we
look
at
how
water
will
change
our
our
future.
C
So
with
that
we'll
go
to
the
next
slide,
I
am
going
to
now
turn
this
over.
Thank
you
all
for
hearing
me
out
in
this
brief
introduction.
At
this
point,
I'm
going
to
turn
it
over
to
our
incredible
team
at
wagner
ball.
The
water
institute
robinson
design
engineers
in
circulation,
who
will
introduce
themselves
as
they
go,
and
thank
you
everyone,
and
now
I
will
turn
it
over
to
to
david
and
andy.
G
G
We
led
the
dutch
dialogues
process.
This
is
something
we
started
a
decade
plus
ago
in
new
orleans
and
it
seems
to
be
a
good
methodology.
The
basis
of
it
is
looking
first
at
ground
and
water,
those
of
us
who
own
buildings
or
live
in
buildings
or
understand
the
top
level
that
we
think
a
lot
about
our
houses.
We
think
a
lot
about
our
buildings.
G
D
D
Just
to
give
you
a
brief
run
of
show
for
this
evening,
I'll
be
doing
most
of
the
talking,
but
we'll
ask
for
some
key
supported
key
moments
from
members
of
our
team.
Aaron
stevens
at
circulat,
local
landscape
architecture,
firm
and
joshua,
robinson
robinson
design,
engineers,
also
there
locally
in
charleston,
and
then
we'll
wrap
it
up
at
the
end.
Dale
morris
at
the
water
institute
of
the
gulf
is
watching
the
chat
window
closely
and
taking
notes.
D
So
please,
as
we
go,
if
you
have
any
questions
put
those
in
the
chat
and
dale
will
collect
those
and
we'll
pose
them
all
at
the
end.
And
finally,
this
is
the
purpose
of
tonight
is
a
technical
presentation
of
our
analytical
method.
This
is
this:
is
an
in
progress?
Look
at
our
work
so
far,
so
this
presentation
is
not
meant
to
fully
explain
all
of
the
landscape
concepts
and
all
of
the
all
of
the
functions
out
there
in
the
landscape
for
a
public
audience.
This
is
a
very
technical.
D
D
The
slides
probably
are
not
going
to
stay
on
the
screen
as
long
as
you'd
like
or
as
long
as
you
need
to
fully
understand
what
we're
saying,
but
I'll
try
my
best
so
who
we
talked
to.
We've
been
engaged
on
the
in
this
project
with
the
city
over
the
course
of
the
summer,
even
since
early
early
in
the
spring,
and
have
tried
to
broaden
our
knowledge
gained
from
dutch
dialogues
to
all
the
areas
across
the
city
like
jacob
mentioned.
D
So
we've
we've
not
been
engaged
in
full
public
engagement,
there's
a
others
in
the
city
working
on
that
effort,
but
we
have
talked
to
key
elected
officials,
city
staff,
business
and
citizen
leaders
to
try
to
get
core
analytical
feedback
that
we
need.
This
process
isn't
finished.
It's
still
ongoing
and
we've
got
a
little
while
left
this
year
to
wrap
this
project
up.
So
would
encourage
your
feedback
if
you
have
any
to
please
reach
out
to
the
city.
D
So
I'll
work
through
a
couple
of
contextual
issues
around
water,
the
the
types
of
water
we're
looking
at
jacob
alluded
to
and
then
how
we're
looking
at
those
water
and
land
types
across
different
scales
in
the
city
and
then
wrap
up
with
a
little
bit
of
what
it
means.
But
we
don't
have
any
recommendations
drafted
at
this
point
so,
first
of
all
rain,
something
everyone's
familiar
with,
as
defined
by
the
noaa
atlas.
14
metrics.
This
is
a
national
data
set
you'll.
D
Just
take
note
that
the
two-year
and
the
25-year
rainfall
events
are
regulatory
design,
storms
in
the
state
of
south
carolina.
So
those
are
important
events,
however
they're
smaller
than
the
types
of
rainfall
that
we
might
be
accustomed
to
seeing
causing
significant
flood
impacts.
Those
are
more
on
the
order
of
magnitude
of
100
year
or
500
year.
Storms.
D
D
D
That
means
for
our
comp
plan
purposes.
Looking
at
a
10-year
look
ahead,
we're
looking
at
somewhere
just
shy
of
one
foot
in
sea
level
rise,
but
we
have
to
be
aware
that
the
decisions
we
make
today
for
land
use
and
construction
will
often
outlive
that
10-year
framework.
So
we're
looking
ahead
towards
30
30-year
length
of
a
mortgage,
for
example,
towards
this
50-year
target
that
the
city
set.
D
Another
water
issue-
storm
surge,
you'll,
see
mapped
in
yellow
here
the
storm
surge
risk.
This
is
mapped
also
by
a
particular
type
of
model
called
the
noaa
slash
model.
This
is
a
representation
in
yellow
of
the
category
3
storm
surge
and
that's.
This
is
a
worst
case
scenario.
Category
3,
storm
surge,
different
types
of
storm
models
are
used
for
different
purposes,
but
for
this
representation
we're
using
kind
of
a
worst
case
event
at
category
three
and
just
for
a
point
of
comparison.
D
Hugo
in
1989
was
a
category
4
storm
at
landfall,
just
north
of
charleston,
with
a
12.9
foot
storm
tied
at
the
battery
and
that
that
did
not
occur
at
high
tide.
So
this
this
this
is
also
an
abstraction.
It's
like,
I
said
it's
the
worst
case
at
every
possible
point.
So
no
storm
would
cause
this
widespread
of
impact,
which
is
again
why
we
need
to
be
looking
at
scenarios
and
ranges.
D
I
should
say
the
storm
surge
is
a
is
a
really
dramatic
and
striking
impact
across
the
city.
However,
it
happens
less
frequently,
so
we
also
need
to
take
that
into
account.
Tidal
and
rainfall.
Flood
events
will
happen
more
often
and
that's
where
we
need
to
think
about
what
the
flood
event
actually
means
in
our
minds.
D
The
point
where
water
might
come
inside,
whereas
a
building
built
on
a
pier
and
beam
foundation,
has
some
ability
for
water
to
flow
underneath
and
also
has
the
ability
to
be
elevated
over
time.
Perhaps,
as
these
scenarios
and
thresholds
change,
I
think
there's
one
thing
for
certain
about
the
low
country
landscape
is
that
it's
dynamic
and
ever-changing,
so
we
need
to
plan,
therefore,
to
adapt
with
it.
D
So
this
map
will
give
you
a
sense
of
our
the
boundary
of
our
study,
which
is
a
little
bit
different
from
other
types
of
planning
in
charleston
and
other
boundaries.
You
might
be
familiar
with
you
see
here
in
dark
gray,
the
charleston
city
limits.
So
that's
the
extent
of
the
city
plan
jurisdiction,
then
you'll
see
the
black
dash
line.
D
D
That
means,
of
course,
water
doesn't
follow
political
boundaries,
so
property
outside
the
city
might
be
impacting
property
inside
the
city
if
runoff
is
transferred
or
flowing
between
the
two.
So
we've
taken
this
wider
view
on
water,
as
it
relates
to
the
city
a
lot
of
these
sub-watersheds
and
these
smaller
purple
lines.
Sub-Watersheds
are
defined
by
topography.
D
You'll
see
here,
the
brown
is
the
high
ground,
relatively
high
ground,
down
to
green
in
the
low
ground.
The
marsh
most
of
the
city
of
charleston
is
in
this
yellow
green
range,
so
you'll
see
that's
kind
of
a
10
to
20
foot
above
sea
level
range.
There
are
areas
of
the
city
that
are
quite
a
bit
higher.
For
example,
you'll
see
this
brown
peninsula
on
the
canehoe
peninsula,
where
some
of
the
land
is
over
30
feet,
even
40
or
50
feet
above
sea
level.
D
So
we've
broken
down
this
wider
watershed
boundary
into
sub-areas
within
the
city
johns
island
outer
west
ashley,
inner
west
ashley,
james
island
peninsula,
daniel
island
and
kane
hoy.
So
those
are
kind
of
our
units
of
study
which
correspond
broadly
to
the
city
of
charleston
vulnerability
analysis,
this
vulnerability
analysis,
work
underpins
our
work
today
and
so
we're
trying
to
align
with
its
with
its
process
and
approach
and
recommendations
as
much
as
possible.
D
D
There's
it's
a
combination
of
a
fema
model
which
includes
flooding
from
rainfall,
includes
flooding
from
tide
and
high
tidal
events,
and
it
also
includes
flooding
from
storm
surge.
It's
using
a
little
bit
different
storm
surge
model
than
that
yellow
map.
I
showed
before
I'll
get
into
a
little
more
detail
about
that
going
forward.
D
D
D
These
ve
zones
are
defined
by
fema
as
areas
that
may
be
subject
to
higher
water,
velocity
and
waves
due
to
storm
surge.
So
these
are
areas
kind
of
at
the
edges
that
would
bear
the
brunt
of
a
storm
surge
risk
and
would
bear
storm
surge
elevations
in
a
different
way
from
areas
elsewhere.
So
those
are
places
of
special
focus.
D
This
presentation
is
going
to
stay
pretty
high
level
and
won't
zoom
in
too
far
just
for
the
the
sake
of
time
today,
but
our
analysis
will
zoom
in
and
and
capture
kind
of
cause
an
effect
at
the
watershed
scale.
Ultimately,
that's
where
we're
headed,
but
for
the
purpose
of
today,
I'm
staying
somewhat
broader.
D
These
are
the
sub-watersheds
in
the
city
and
give
you
a
sense
of
the
scale
of
the
sub-watersheds
and
how
they
change
across
the
city.
So,
for
example,
this
is
the
church
creek
watershed
in
west
ashley,
it's
quite
large,
so
it
has
a
significant
flow
length
I'll
get
into
what
that
means.
What
the
upstream
and
downstream
conditions
are
and
how
they're
different?
Why
that's
important
you'll
see
in
some
other
parts
of
the
city
like
inner
west
ashley
around
the
edges?
As
you
get
around
the
rivers
and
and
the
sea,
the
watersheds
tend
to
get
smaller.
D
There
are
smaller
areas
that
drain
directly
into
the
rivers,
for
example
with
less
of
that
upstream
downstream
impact
so
that
that's
important
for
land
use
coming
up,
but
moving
around
the
rest
of
the
city.
Here
you
see
john's
island,
we'll
just
pause
here
for
a
minute
one
of
the
larger
watersheds
from
john's
island
burden,
creek.
D
Again,
you
see
how
the
watersheds
sort
of
conform
to
topography
if
you're
familiar
at
all
with
this
area.
You
know
that
the
old
dune
structures
run
parallel
to
the
coast
on
john's
island,
and
you
see
some
of
the
watersheds
reflecting
that
that
underlying
geology,
I'm
also
on
james
island.
I
would
note
that
the
largest
watershed
on
the
island
is
james,
island,
creek,
here
primarily
tidal,
even
in
its
higher
reaches,
even
though
it's
so
large,
it's
relatively
low
lying.
D
One
thing
to
point
out
here
is
on
daniel
island.
You
see
that
much
of
the
island
is
light.
Blue
much
of
the
island
is
in
that
100
year
floodplain,
and
something
interesting
that
we've
heard
from
stakeholders
around
the
city
is
that
daniel
island
does
not
report
the
same
level
of
flooding
from
rainfall
as
other
parts
of
town
and
what
we've?
D
What
we've
heard
in
the
working
hypothesis
is
that
this
area
has
a
more
functional,
better
maintained
drainage
system,
despite
its
relatively
low-lying
elevation
that
allows
water
to
drain
away
more
quickly,
more
efficient
manner,
despite
the
fact
that
it's
so
low-lying
and
that's
that's
under
the
current
sea
levels.
So
that's
something
again
to
project
forward
as
those
river
and
sea
levels
change
over
time.
D
Okay,
so
here
those
blue
those
light
blue
areas
are
now
shown
in
green
and
we've
added
the
orange,
which
is
the
additional
portion
of
the
city
at
risk
of
storm
surge
category
3
storm
surge.
It's
important
to
note
here
this
is
the
100-year
flood
plain
defined
by
fema.
This
is
the
category
3
maximum
storm
surge
defined
by
the
noaa
slash
model,
the
different
modeling
types,
this
category,
three
storm
surge,
the
yellow,
is
really
building
up.
D
D
The
landscape
of
the
low
country
is
characterized
by
three
basic
types:
aaron
we'll
get
into
this
a
little
bit
more.
In
a
few
minutes,
the
coastal
edge
condition
the
salt
marsh.
The
flood
plain
low-lying
flood
plain
with
some
variety
of
elevation
within
it.
It's
not
all
at
the
same
level
and
then
the
upland
condition
those
remnant
dune
geological
sand,
dune
structures
in
the
landscape
the
highest
ground.
D
D
D
So
I'll
just
spend
a
minute
on
this
graphic.
This
is
the
next
few
are,
are
pretty
data-heavy
so
again,
I
would
encourage
you
to
download
this
presentation
online
following
this
event
to
study
more
closely,
but
what
this
drawing
represents.
What
this
chart
represents
is
the
land
within
the
flood
plain
the
100
year,
flood
plain
per
elevation
and
then
the
land
within
that
orange
shape
the
storm
surge
risk
area
by
elevation.
D
D
D
Then
you'll
see
on
top
of
that
building.
On
top
of
that
is
the
storm
surge
risk,
which
also
affects
different
areas
of
the
city
at
different
elevations
into
different
water
depths.
That's
something
that
is
building
on
top
of
more
frequent,
tidal
and
rainfall
risk,
but
can
impact
the
city
up
to
a
much
higher
elevation.
D
So
now
we'll
map
those
elevation
thresholds
across
an
average
in
the
city.
This
is
a
this
is
a.
This
is
an
average
of
all
the
land
elevations
within
the
urban
growth
boundary.
So
we
see
a
range
of
land
all
the
way
from
sea
level
up
to
over
30
feet.
Small
percentage
of
land
in
the
city
within
the
ugb
is
above
30
feet.
D
Most
of
the
land
is
occurring
in
this
kind
of
range
up
to
about
15
15
18
feet
on
this
side
of
the
graph.
You
see
tidal
flood
thresholds.
This
is,
according
to
the
charleston
harbor
gauge
the
major
tidal
flooding
threshold,
which
was
hit
a
couple
of
times
based
on
king
tides.
Over
the
last
couple
of
days,
there
is
eight
feet
above
mean
lower
low.
D
These
ranges
are
projected
to
increase,
of
course,
as
sea
level
rise
increases.
So
what
we're
trying
to
do?
One
of
the
things
we're
trying
to
do
through
this
analysis
is
identify
these
risk
thresholds
and
then
apply
those
to
specific
areas
of
the
city,
see
what
the
impacts
are
and
what
adaptive
strategies
might
be
put
in
place
there.
D
D
If
we
overlay
now
those
floodplain
percentages
and
storm
surge
percentages
based
on
elevation,
I
think
you
you
where
this,
where
you
get,
you
get
a
sense
that
this
land
below
10
feet
and
there's
there's
a
there's
a
range
here,
of
course,
but
this
land
below
about
10
feet
is
subject
to
multiple
different
types
of
flood
risk.
More
often,
a
high
percentage
of
that
land,
those
elevations
the
percentage
of
land
subject
to
flood
plain
and
storm
surge
risk
diminishes
as
you
get
higher.
D
D
We
did
in
dutch
dialogues
on
john's
island
if
you're
familiar
with
that
report
at
all
where
we
outlined
a
couple
of
key
thresholds
across
the
island
based
on
water
risk
and
the
type
of
developments
that
we
felt
would
be
most
suited
to
those
ranges,
kind
of
taking
that
methodology
now
and
applying
it
across
the
rest
of
the
city
in
in
a
much
more
rigorous
way.
I
mean
you
remember:
dutch
dialogues
was
a
fast
high-level
process
and
now
we're
able
to
get
more
a
little
more
into
the
detailed
information.
D
D
John's
island
has
a
little
bit
more
land
at
high
ground
than
elsewhere
in
the
city,
all
right
at
a
higher
elevation,
but
you
see
the
tidal
title
levels
and
then
eventually
trying
to
map
this
tidal
risk
combined
with
compound
flood
risk
across
all
of
the
zones.
So
again,
this
is
not
a
specific
level
recommended
here.
This
is
a
zone
and
a
range,
that's
being
refined
per
individual
focus
area
as
we
proceed
in
our
analysis,.
D
D
So
this
this
is
kind
of
a
first
attempt
to
synthesize
and
see
where
that
compound
flood
risk
zone
occurs
in
space
and
how
it
might
be
changing
over
time
as
we
project
through
multiple
scenarios.
In
this
case,
this
is
representing
a
three
level.
Three
foot
sea
level
rise
scenario,
so
those
elevation
ranges
will
be
changing
over
time,
as
they
have
changed
over
time
for
the
history
of
of
the
low
country.
D
D
D
D
So
first
attempt
at
mapping
where
that
marsh
migration
might
occur,
also
where
marsh
loss
will
occur
as
sea
level
rise
will
is
expected
to
drown
some
areas
of
existing
salt
marsh.
The
water
will
just
get
too
deep
in
those
in
those
areas
to
sustain
the
marsh
grass
and
that
ecological
community.
So
that's
what
you
see
in
red
wetlands
in
the
darker
red
that
are
that
we
expect
to
be
lost
in
a
three-foot
sea
level,
rise
scenario
and
light
red
wetland
marsh
areas
at
risk.
D
In
green,
you
see
where
those
marshes
may
naturally
tend
to
migrate.
That's
moving
up
these
tidal
creeks
and
that
depends
on
that
depends
on
the
land.
Surface
condition.
As
you
move
inland
depends
on.
The
slope
depends
on
soil
qualities
and
what's
built
there,
whether
there's
a
road
in
the
way,
for
example.
D
D
A
place
to
store
rainfall
without
causing
flooding,
you
can
use
these
natural
ecosystem
functions
as
opportunities
and
so
a
further
layer-
and
I
know
this
is
a
bit
hard
to
read,
but
a
first
stage
analysis
at
what
the
what
those,
what
that
migrating
marsh
might
be
expected
to
find
in
terms
of
current
land
uses
as
it
moves
into
the
tidal
creeks
you'll
notice.
There's
a
I'll
go
back
back
and
forth
one
time
here,
so
focus
on
the
green.
D
These
light
green
shapes,
like
here,
for
example,
kind
of
the
rantal's
creek
area,
that
portion
of
land
is
currently
a
woody
wetland.
So
most
of
the
areas
the
marsh
is
expected
to
migrate,
at
least
in
the
near
term,
are
currently
naturalized
conditions.
That
might
be
a
benefit
for
this
ecosystem
to
sustain
itself.
B
Thanks
andy
again,
my
name
is
aaron
stevens,
I'm
a
landscape
architect
here
in
charleston
and
what
we're
trying
to
show
with
these
graphics.
Here,
it's
it's
visualizing.
What
andy
was
just
talking
about
at
the
the
landscape
scale
and
as
he
mentioned
as
the
sea
levels
rise
and
as
saltwater
moves,
inland
and
upland.
We
need
to
allow
for
some
areas
for
our
marsh
to
migrate
as
well.
B
Whereas
if
we
do,
you
know
a
structural
bulkhead
to
prevent,
you
know
that
marsh
migration,
eventually,
it
will
go
extinct
because
it
will
have
nowhere
to
go.
It
can't
travel
up
the
face
of
the
wall
so
again,
just
emphasizing
the
importance
of
keeping
keeping
a
soft
edge
where
we
expect
the
marsh
to
migrate,
and
then
another
component
that
we're
showing
here
is
that,
in
addition
to
changing
locations
of
our
saltwater
marshes,
the
sea
level
rise
projections
also
have
the
potential
to
create
freshwater
wetlands
from
emerging.
B
If
you
want
to
flip
to
the
next
slide,
I
think
that's
all
so
what
we've
done
here
is
looking
at.
You
know
these
future
hydrologic
conditions
that
we're
starting
to
be
able
to
predict
with
the
maps
that
we
just
looked
at
looking
at
soil
types,
which
joshua
will
get
into
more
detail
about
later,
but
basically
how
well
specific
soil
types
drain
or
don't
drain
looking
at
flood
risk
and
then
looking
at
elevation.
B
We
began
to
develop
these
landscape
typologies,
so
if
we
are
either
preserving
or
promoting
the
preserving
existing
vegetation
or
promoting
the
revegetation
reforestation
of
these
areas,
it's
really
important
that
we
choose
the
right
plants
that
will
be
most
durable
in
the
face
of
these
anticipated
changes.
So
we've
developed,
you
know
images
kind
of
showing
the
iconic
landscapes
that
we're
describing
here
with
a
list
of
recommended
plants
that
will
be
most
durable
in
these.
B
These
changing
conditions,
and
so
all
of
these
also
are
native
plants,
because
they
they
provide
great
ecosystem
services
and
can
support
the
habitat
necessary
to
preserve.
You
know
the
the
natural
elements
within
within
our
city
and
now
I'll
turn
it
back
over
to
andy
hill.
Talk
more
about
the
structural
and
housing
typology
implications
for
these
various
conditions.
Thanks.
D
Thank
you,
aaron,
and
I,
I
think,
just
building
on
putting
a
point
on
one
thing.
You
said
about
landscape
adaptation.
We
often
think
about
how
buildings
in
the
built
environment
need
to
change
for
a
resilient
city,
but
equally
important
is
landscape
adaptation
and
especially
as
someone
who
doesn't
live
in
charleston,
it's
it's
striking.
How
beautiful
the
salt
marsh
and
the
natural
landscape
of
charleston
is
naturally
and
so
also
important.
D
I
think
to
recognize
the
beauty
of
that
landscape
and
it's
and
it's
just
inherent
value
that
way,
but
buildings
and
the
built
environment
also
need
to
evolve.
As
as
the
the
low
country
landscape
changes,
there
are
certain
types
of
of
constructions
that
are
more
flood
adaptive
than
others.
I
think
in
many
ways
this
is
really
simple
logic:
homes,
for
example,
built
on
pier
and
beam.
D
Allow
flood
water
to
move
underneath
them
can
be
raised
over
time,
whereas
homes
built
on
slabs,
whether
they're
on
existing
ground
or
they're,
built
up
on
landfill
on
fill
dirt
are
inherently
more
difficult
to
adapt,
they're
much
harder
to
lift
up
and
change
over
time
same
for
commercial
buildings.
Those
tend
to
be
a
bit
more
fixed,
maybe
a
bit
of
a
longer
term
investment,
yet
they
can
still
be
adapted,
whether
that's
dry
floodproof,
whether
it's
allowing
a
raised
floor
inside
new
types
of
access
or
whether
they're
reconstructed,
perhaps
at
a
little
bit
higher
elevation.
D
D
Only
if
additional
mitigation
measures
are
taken
to
store
extra
flood
water
and
mitigate
the
runoff
surrounding
that
property,
whereas
the
unmodified
slab
on
grade
of
course,
is
is
subject
to
flooding.
Basically,
sandbagging
is
the
opportunity
there
and
water,
especially
if
it's
tidal
and
salt
water
has
pretty
detrimental
impacts
on
buildings,
and
so
these
recommendations
start
to
play
out
in
space
and
have
different
value
in
different
parts
of
the
city.
D
They
can
provide
kind
of
just
a
quick
glimpse
at
different
ways
forward
in
terms
of
adapting
and
also
adapting
existing
structures.
What
kinds
of
changes
might
be
needed,
as
well
as
building
new
structures
for
the
future?
Not
using
the
same
types
of
methodology
that
have
elevated
risk
up
to
the
present
moment,
so
part
of
the
analysis
has
been
to
capture
the
land
cover
types
across
the
city.
D
D
D
So
what
you
can
take
away
from
this,
drawing
first
of
all
on
the
left.
Here's
the
curve,
if
you
remember
that
curve
from
john's
island,
the
land
surface
per
elevation,
here's
the
flood
plain
risk
per
elevation
percentage
of
land.
In
the
flood
plain,
and
here
on
the
right
side,
you
see
the
land
cover
per
elevation
foot
per
foot
of
elevation.
D
The
main
thing
is
this
gray
shape
that
indicates
land
outside
the
urban
growth
boundary.
So
there
is,
if
you
look
in
this
10
10
foot
and
above
range,
there's
a
lot
of
gray
stuff
out
there,
but
it's
outside
the
urban
growth
boundary,
even
though
it's
high
ground,
potentially
perhaps
suitable
for
certain
types
of
development.
D
D
If
we
compare
inner
west
ashley,
this
is
just
a
flip.
To
compare
two
you'll
see
that
it's
a
lot
more
developed,
there's
a
lot
more
red
and
pink
you'll
see
that
that
development
occurs
primarily
in
this
mid
elevation
range,
it's
a
little
bit
lower
down
than
john's
island,
so
I'll
flip
back
and
forth.
Just
to
compare
here's
john's
island,
you
see
that
curve
includes
some
higher
ground
and
more
green.
D
Here's
west
ashley
curve
came
down
a
little
bit
less
availability
of
naturally
high
ground
and
more
developed.
So
what
does
that
mean?
What
are
the
consequences
of
this
development
and
type
of
development
to
understand
that
we
have
to
understand
the
different
types
of
watersheds
and
where
that
development
is
occurring
within
it?
So
we
have
identified
we've
classified
basically
small
and
large
watersheds
across
the
city.
D
The
large
watersheds
include
this
upstream
condition,
whether
it's
a
low-lying
watershed
such
as
james
island
creek,
it's
mostly
tidal,
so
even
the
upstream
condition
is
titled
or
something
like
church
creek.
Where
you
have
this
upstream
condition,
that's
not
tidal.
It's
subject
to
different
kinds
of
flood
risk.
D
D
These
are
determined
through
our
analysis,
based
on
the
length
of
the
creek
channel
based
on
the
the
distance
storm.
Water
has
to
flow
from
the
farthest
inland
condition
until
it
reaches
the
outlet
and
so
we've
that
that's
sort
of
an
indication
of
how
many
steps
that
runoff
has
to
go
through
before
it
finally
drains
how
many
people,
along
the
way
it
could
potentially
impact
people
in
properties
that
type
of
analysis.
D
D
A
A
You
know
it's
going
to
become
a
better
idea
to
move
into
the
higher
ground,
and
these
higher
ground
areas
are
are
shown
here,
as
andy
described
in
this
darker
blue
color.
The
question
we've
also
been
asking
is
as
we
as
we
move
further.
You
know
in
deeper
into
the
landscape
onto
this
this
higher
ground.
How
do
we
do
so
in
a
way
that
does
it
create
new
stormwater
flooding
problems?
A
So
as
we
move
upward
to
try
to
avoid
the
tidal
flooding
problems,
how
do
we
be
responsible
neighbors
to
those
living
downstream,
especially
in
these
large
watershed
areas
where
there
are
some?
You
know
large
developed
areas
downstream
of
these
areas
and
we
don't
want
to
create
new
storm
water
flooding
that
will
travel
downstream
and
create
flooding
problems.
We
don't
currently
have,
because
what
we
do
upstream
affects
everything
downstream
and
it
affects
things
that
are
in
the
immediate
vicinity.
A
A
So
really
this
gets
to
the
question
the
fundamental
question
about
stormwater
flooding,
which
is
how
much
rainfall
becomes
runoff,
and
so,
as
we
you
know,
do
flood
studies
and
think
about
how
much
of
this
rainfall
is
converted
into
stormwater
runoff.
The
two
main
factors
are
land
cover
and
soils,
and
so
it's
pretty
obvious
that
you
know
a
parking
lot
will
shed
more
water
than
a
forest
will
or
a
rooftop
will
shed
more
water
than
a
grassed
area.
But
what
we
don't
often
think
about
is
is
what
do
the
soils
themselves
do?
A
How
do
they
absorb
water?
So
the
the
soils
you
see
here
shown
in
green,
which
are
in
hydrologic
group
a
and
hydrologic
group
b?
These
are
the
the
classes
of
soils
you
can
think
of
them
as
sandy
soils
that
have
a
very
high
infiltration
rate
or
they
can
absorb
a
lot
of
storm
water,
whereas
the
soils
in
the
yellow
and
the
brown
shades
that
are
group
c
and
group
d.
These
are
the
soils
that
you
can
think
of
to
be
more
like
clays,
that
can
absorb
so
much
water
and
they
create
more
runoff.
A
A
A
Whereas
if
you
look
at
the
hydrologic
soil
groups
group
a
again,
that's
the
soil
group,
the
green
soils
there
that
are
on
the
high
the
highest
areas,
those
are
the
sandy
soils.
Those
are
the
soils
that
are
basically
ancient
sand
dunes
ancient
beach
features
that
are
that
have
a
high
infiltration
rate,
something
like
a
group,
a
soil.
If
you
have
six
inches
of
rainfall,
only
about
two
inches
of
that
rainfall
is
converted
into
runoff
and
where
does
the
rest
of
the
water
go?
A
Well
the
rest
of
the
water
soaks
into
that
soil
to
be
part
of
the
shallow
groundwater
to
then
be
used
by
the
vegetation
to
evapotranspirated
back
up
into
the
sky.
So
this
helps
us
think
about
again.
How
can
we
use
the
soils
and
the
landscape?
The
vegetation
like
aaron
mentioned?
How
can
we
use
the
actual
natural
landscape
to
manage
more
storm
water
as
we
move
up
into
these
high
ground
areas
so
as
to
not
cause
new
flooding
problems
downstream.
D
A
Yeah,
thank
you.
Andy.
That's
a
great
question.
You
know.
One
one
thing
to
point
out
is
that
nothing
manages
stormwater
better
than
a
wetland.
You
know,
because
wetlands
are
shallow
ponded
areas
that
are
filled
with
vegetation
and
they
hold
storm
water
during
and
immediately
following
a
rain
event.
But
then
they
also,
you
know
let
a
lot
of
that
water
go
back
into
up
into
the
sky
through
through
trees.
A
A
Perhaps-
and
that's
that's
a
that's
a
difficult
question,
but
the
open
water
areas
are
they're
holding
a
lot
of
water,
they
have
the
potential
to
hold
a
lot
of
water
and
let
some
of
that
water
evaporate
back
up
into
the
sky,
but
the
only
better
condition
would
be
an
actual
wetland
if
it
were
to
be
converted
back
into
a
wetland.
So
then,
it's
not
just
open
water,
but
it
actually
has
the
trees
and
other
vegetation
to
create
the
evapotranspiration.
D
D
So
one
final
map,
for
you
is
the
overlay
of
watersheds
in
politics-
and
this
is
a
recurring
theme
that
we
heard
in
all
of
our
conversations
with
with
people
around
the
city.
Is
that
it's
very
difficult
to
understand.
Sometimes,
the
the
the
political
jurisdictions
in
charleston
are
quite
difficult
to
understand
between
properties
that
fall
within
a
public
service
district
within
within
the
city
within
the
county,
within
an
unincorporated
area
within
another
town.
D
So
this
is
a.
This
is
a
tricky.
This
is
a
tricky
problem
beyond
the
scope,
the
political,
the
political
jurisdictions
and
alignments
and
coordination.
It's
not
part
of
our
project
right
now,
not
part
of
our
of
our
direct
recommendations,
but
just
trying
to
give
some
visibility
into
where
that
additional
coordination
will
be
required.
D
Okay,
just
to
reiterate
bringing
back
jacob's
slide
from
earlier
on,
there's
a
range
of
strategies
that
correspond
to
a
range
of
possible
future
conditions
in
charleston
those
land
and
water
conditions
vary
in
elevation,
vary
in
surface
type
and
cover
they
vary
based
on.
What's
already
been
built,
what's
proposed
to
be
built
what's
yet
to
be
built,
all
of
these
all
of
these
factors
occur
in
multiple
scenarios
and
in
different
ranges.
D
It's
not
a
one-size-fits-all
solution
everywhere,
but
there
are
opportunities
that
come
out
of
an
analysis
like
this,
whether
that
be
based
on
ways
to
take
advantage
of
favorable
soil
types
or
elevations
ways
to
anticipate
future
water
changes
at
the
edge
as
compound
flooding,
type
or
upstream,
the
relationship
between
them
all
so,
ultimately,
our
project
is
a
is
a
technical
analysis.
We
will
be
giving
this
our
results
to
the
city.
D
So
with
that,
we'll
turn
it
over
to
questions
looks
like
we've
got,
maybe
about
20
20
25
minutes
left
in
our
scheduled
time
and
dale
morris
has
been
closely
watching
the
chat
window.
Maybe
we'll
save
a
few
minutes
at
the
end
dale
for
chloe
to
wrap
up
with
the
next
steps
in
the
comp
plan.
But
dale,
can
you
tell
us,
give
us
an
update
on
the
chat
window.
F
Sure,
thank
you
andy
and
thanks
all
friends
in
charleston
for
listening
to
this,
a
lot
of
information
was
thrown
at
you.
My
head
hurt
this
morning
after
watching
annie
go
through
this,
and
so,
if
your
head's
hurting
too,
then
then
then
we
share
that
again.
This
is
there's
a
lot
of
information
here.
The
information
will
be
available.
F
This
presentation
will
be
available
to
you
as
a
download
from
the
city
after
this,
and
one
thing
to
keep
in
mind
is
that
the
information
that
we
will
give
to
the
city
will
have
a
fair
amount
of
granularity
to
it
that
we
kept
this
at
a
high
level,
so
it
is
digestible.
But
again
we
understand
that
it
is
a
lot
of
information
to
take
in
so
spend
some
time.
F
Looking
at
it
and
some
of
your
questions
or
concerns
may
be
answered,
I
tried
to
answer
a
few
of
the
questions
as
they
as
they
came
in
through
the
chat,
but
there
are
a
few
that
I
think
our
team,
maybe
even
the
city,
would
want
to
weigh
in
on,
and
one
of
the
questions
was
clearly
why
we
didn't
list
a
number
of
key
citizen
stakeholders
on
the
peninsula
that
we
engaged
with.
So,
as
I
put
in
the
chat
our
team
through
the
dutch
dialogues,
we
understand
in
the
effort
through
the
dutch
dogs.
F
We
understand
very
well
the
various
water
challenges
on
the
peninsula
because
of
the
study
for
the
dutch
dialogues.
Looking
at
the
east
side,
looking
at
the
entire
peninsula
and
looking
at
the
medical
district,
we
did
have
a
shortcoming
of
information
on
wagner,
terrace
and
rosemont
and
maybe
parts
of
the
neck,
but
some
of
that's
north
charleston.
F
So
we
spoke
with
people
there
and
you
know
over
the
last
course
of
last
year
we
have
been
speaking
with
a
lot
of
people
continually
about
the
peninsula
challenges,
so
we
spent
most
of
our
time
for
this
comp
plan
work.
Looking
at
the
other
parts
of
the
city
that
we
didn't
understand
so
well,
because
we
didn't
look
at
it
last
year,
so
it
wasn't
that
we
ignored
the
peninsula,
but
we
had
a
fair
amount
of
information
about
it,
so
we
felt
confident
there.
Another
question,
fairly,
simple
to
answer
is
andy.
F
When
you
referred
to
james
island
and
james
island,
creek
being
the
primary
watershed
that
we
can
see,
impacts
from-
and
we
have
to
have
to
ponder
very
closely,
how
do
you
manage
those
impacts?
Was
that
the
only
thing
we
were
looking
at
and
the
answer
is
no
not
at
all?
That
is
a
watershed
that
we
have
to
pay
attention
to,
but
we
have
looked
at
many
parts
of
james
island
around
the
edge
don
folly
road
in
some
of
the
very
particular
neighborhoods
I
spoke
with
some
citizens
whose
names
are
listed.
F
We
all
we
all
did
and
picked
up
their
information,
so
it
wasn't
that
james
island
creek
is
our
only
focus.
It
just
is
a
watershed
that
we
really
have
to
pay
attention
to
then
I'll.
Ask
mr
ward
asked
a
question,
and
perhaps
the
team
can
can
weigh
in
on
this.
The
question
was
really
about
the
pace
of
landscape
change.
F
Also,
as
andy
noted
it,
it
depends
on
the
nature
of
the
edge
of
the
marsh.
Is
it
hardscape
or
is
it
soft
and
amenable
to
allowing
the
marsh
to
migrate
there,
and
it
also
relates
to
something
called
the
sediment
budget,
which
is
you
know?
Is
there
subsurface
sediment
where
the
marsh
can
can
attach
itself
and
start
to
grow
and
that
will
occur
naturally,
as
the
grasses
go?
F
B
I
think
you
covered
a
lot
of
the
important
points.
I'd
also
say
one
other
factor
that
is
important
to
think
about
in
predicting
where
it's
likely
to
happen.
It
depends
too
on
the
slopes
at
the
banks.
You
know
where
you
have
a
steeper
slope,
you're
less
likely
to
get
the
marsh
because
it
needs
that
flat
landscape
to
travel
into
so
again,
I
think
there
are
a
lot
of
factors
that
go
into
it.
So
it's
there's
not
a
simple
answer.
B
D
Dale
I'd
just
like
to
to
jump
in
and
acknowledge
a
question
that
I
think
I
got
maybe
just
I
saw
privately
from
a
man
named
rick
dawson
on
the
line
and
mr
dawson
just
like
to
acknowledge
your
your
response
about
migration
and
some
of
the
changes
there.
I
may
just
read
this
out.
I
think
this
is
useful
for
others
to
to
understand
and
some
of
your
other
other
questions
too.
Mr
dawson,
but
marshall
migration
related
to
the
salt
line
for
jurisdictional
purposes.
D
He
says
the
changes
in
wetland
plant
species
will
drastically
affect
coastal
productivity.
Have
you
calculated
that
impact
to
coastal
fisheries
and
colonial
bird
communities?
Have
you
considered
the
threat
of
invasive
species
establishing
themselves
if
this
environment
changes
too
fast
or
can't
re-establish
itself
after
a
catastrophic
storm?
A
F
Great
and
as
you
as
citizens
charleston
know,
there
are
many
really
smart
people,
academics
and
professors
over
the
college
of
charleston
and
at
the
citadel
who
have
a
lot
of
knowledge
about
this,
and
they
have
been
consulting
with
us.
We
have
stayed
in
touch
with
them
since
the
dutch
dialogues-
and
I
think
the
city
has
a
great
opportunity
to
consult
with
them
when
they
take
our
analysis
and
try
to
turn
this
into
into
recommendations
for
the
planning,
commission
and
possible
recommendations
for
the
for
the
future
zoning
code
changes.
F
So
this
is
a
work
in
progress,
but
it
is
it's
a
it's
a
very
important
topic
and
I
think,
if
you
see
some
of
the
maps,
you'll
get
a
sense
where
it's
very
clear
that
some
land
is
going
to
have
to
be
reserved
going
forward
so
that
the
marshes
can
migrate
to
do
all
the
wonderful
things
that
they
do
I'll
move
on
to
another
question-
and
this
is
from
mr
john
zugler-
and
he
is
referring
to
the
building
typology
slide
andy,
and
maybe
you
want
to
put
that
up.
He
says
you
know.
F
How
do
we
encourage?
You
know
commercial
structures
to
be
post
and
beam,
and
how
do
we
encourage
to
put
parking
on
the
ground
floor
and
whatever
elevate
above
it,
so
you
can
have
resiliency
from
water
events
and
minimize
impervious
surfaces.
So
this
is
an
urban
design
and
an
architecture
question
as
well
as
a
land
use
question.
G
Yeah
this
david,
I
think
it's
a
great
question.
You
know
we
we
seem
to
have
forgotten
what
the
commercial
structures
in
the
past
looked
like
along
rivers
and
so
forth.
You
know
the
elevated
stores
with
the
raised
porches
and
those
stores
were
all
raised
and
we
went
up
steps
to
them.
The
the
challenge
becomes
more
and
more
the
ability
to
provide
universal
access.
G
So
we
can't
just
have
the
steps
up
to
a
store
or
commercial.
We
have
to
have
some
kind
of
platform.
We
established
the
more
you
aggregate,
those
the
easier
it
is
to
provide
access
at
either
end
and
raise
the
structure
up
to
two
or
three
feet
that
might
be
valuable.
In
that
case,
the
question
asked
about
parking
underneath
is
an
abrupt
question
in
an
existing
neighborhood.
G
It
often
looks
out
of
place,
or
you
know,
peculiar
to
the
condition.
If
it's
planned
into
a
development,
it
can
be
done
parking
underneath
works.
Fine,
you
flood
the
car
and
you're
safe.
You
still
have
to
get
the
access
for
the
individual
up,
but
I
really
appreciate
the
question
about:
why
aren't
we
building
commercial
structures
also
in
an
elevated
way,
on
a
pier
and
beam?
G
We
we've
been
looking
at
this
for
years
and
how
do
you
just
get
the
access
more
universally
up
to
more
buildings
and
not
just
a
single
store
without
having
to
do
lifts
and
all
that,
but
still
the
right
question
the
right
way
of
thinking?
Why
not
raise
things
a
bit
out
of
the
floodplain
and
then
get
us
and
let
us
come
up
to
them
instead
of
rolling
in
or
driving
in,
as
we
we've
gotten
used
to
doing.
F
Okay,
great
I'll
move
on
to
another
question:
this
is
a
this
is
a
difficult
one,
but
it's
one
that's
been
looming,
it's
looming
not
only
in
the
coast
of
south
carolina,
but
it's
looming
in
most
coastal
areas
in
the
u.s.
It's
clearly
looming
and
happening
in
some
other
places
it's
regarding
retreat
and
it
was
just
a
question.
You
know
why
isn't
retreat
or
why
is
it?
F
As
you
know
there,
the
marshes
have
been
substantially
degraded
for
a
lot
of
reasons,
some
man-made
some
natural,
but
there
are
a
lot
of
wonderful
communities
in
the
in
in
the
marshes
in
acadiana
and
it's
very
tricky
to
decide
what
to
do
with
that.
But
louisiana
is
struggling
with
this
parts
of
texas
are
struggling
with
this
there's
parts
of
new
jersey
that
are
struggling
with
this.
There
are
communities
along
the
rivers,
starting
on
the
upper
stem
of
the
mississippi
river
in
iowa
and
in
whatever
further
north
of
that
that
are
strong.
F
G
I
think
the
the
broad
retreat
thing
like
it's,
an
army
withdrawing
from
a
field
or
something
is
maybe
one
scale,
but
there's
also
the
more
surgical
aspect
of
in
certain
places.
You
have
one
or
two
properties
where
the
water
does.
They
are
the
places
that
flood
we've
heard
that
discussion
from
our
interviews
with
charlestonians
that
there's
this
corner
over
there
that's
low
and
that
house
floods
all
the
time.
I
think
that's
another
scale
of
action
that
could
be
taken.
It's
not
broadly
retreat.
It's
a
really
re
neighborhood
relocations
in
some
cases
like
that.
G
F
Right
and
that's
a
wonderful
point,
david
and
it's
important
to
remind
folks
that
in
charleston
they're,
you
know
with
the
buyouts
in
shadow
moss
and
other
bias
that
have
occurred
in
a
on
a
hard
basis.
I
mean
that
is
in
essence,
every
street
strategy,
this
tactical
one
that
david
mentioned,
and
so
this
doesn't
have
to
be.
F
As
david
mentioned,
abrupt
or
or
you
know,
a
massive
movement
of
people
that
you
know
can
occur
over
time
and
depending
on
how
the
city
adapts
to
rising
waters,
maybe
retreat
is
not
retreat
in
the
scale
that
we've
suggested
is
not
not
necessary
and
we'll
get
to
that.
I'm
going
to
move
on
to
another
question
and
I
have
to
read
it
here
so
there's
a
question
about:
have
we
been
looking
at
polluted
areas?
D
F
G
We
hope
we
are
considering
it
we're
hopefully
going
to
have
an
agreement
with
the
city
that
we
lets
us
advise.
Our
intention
is
not
to
take
an
independent
position,
but
a
position
in
support
of
the
city,
so
I
I
think
that
we'll
we
hope
to
provide
counsel,
it's
a
subtle
condition.
Obviously
it's
quite
involved,
but
in
the
period
between
now
october
and
december,
we
hope
to
provide
that
council
to
the
city
working
with
the
design
department
directly.
D
I
think
just
to
just
to
build
on
that
point.
We
are
not
considering
directly
the
three
by
three
within
the
study
of
the
within
the
comp
plan
analysis.
This
is
a
broader,
really
real
trying
to
capture
regional
approach
to
land
and
water.
So
that's
that's
even
a
little
bit
finer
scale
than
I
think
we'll
get
to
for
the
purpose
of
this
analysis.
Maybe
a
separate
a
separate
engagement
to
deal
with
those
issues
at
a
finer
scale.
F
F
It's
going
to
be
up
to
you
to
work
with
the
city
leaders
and
the
planning
commission
to
help
design
create
the
city
that
you
want
going
forward.
So
our
work
is
just
to
support
that
to
give
you
foundational
information,
but
these
land
use
decisions
are
what
we
call
political
decisions
and
the
decision
on
that
has
to
go
through
those
processes,
and
so
we
wish
you.
You
know
the
best
with
that.
Our
team
appreciates
the
challenges
in
charleston
that
are
there.
F
We
understand
these
are
not
easy
things,
they're
not
easy
anywhere,
but
we
also
appreciate
the
struggle
that
you're
going
through
it's
again,
it's
difficult,
but
we
also
respect
very
clearly.
To
put
it,
we
respect
very
clearly
the
knowledge
that's
already
within
the
city
of
charleston,
in
its
citizens
and
its
stakeholders
and
within
government
to
try
to
manage
this
successfully
going
forward.
E
Thanks
everyone:
this
is
chloe
stewber,
I'm
with
the
city
of
charleston
the
planning
department,
I'm
working
really
closely
with
our
engagement
team
at
gathering
public
input
throughout
this
planning
process.
So
I
want
to
appreciate
everyone
who
has
attended
tonight
and
especially
those
who've
attended
both
morning
and
evening
sessions.
This
is
a
lot
of
information.
We're
really
excited
to
be
able
to
be
transparent
about
the
analysis
that
is
going
on
behind
the
scenes,
and
we
understand
it's
a
lot
of
information,
so
we
will
one.
E
This
meeting
is,
is
being
streamed
to
youtube
and
will
be
on
the
city
plan,
youtube
playlist

watch
as
many
times
over
as
you
can
stand,
and
also
we'll
have
the
slides
from
tonight
we'll
share
out
with
everyone
in
a
follow-up
email
afterwards.
So
you
can
look
over
those
more
closely
and
also
down
the
road
when
we
have.
You
know
the
final
analysis
we'll
be
working
on
creating
some
educational
materials
that
are
a
little
bit
more
boiled
down
that
you
highlight
the
main
takeaways
from
this
so
more
to
come.
E
Where
we're
you
know
we're
in
the
beginning
stages
of
this
planning
process,
and
so
there
will
be
many
more
opportunities
to
get
involved.
Can
you
go
back
one
more
slide,
so
I
could
go
back

I
want
to
highlight.
