Jacob
I'm
glad
you're
here
we're
going
to
get
some
words
of
advice
for
you
and
and
congratulate
you
on
your
new
position.
You
know
when,
when,
when
team
keen
got
his
job
up
in
atlanta
I'll
never
forget,
I
called
him
to
congratulate
him
and
it
was
a
friday
afternoon
and
he
happened
to
be
in
atlanta.
I
think
he
was
looking
for
a
place
to
live.
It
was
friday
afternoon
and
he
was
in
buckhead
and
he
said
wow.
He
said
I
don't
know
what
I'm
into
here.
E
This
is
crazy,
so
it
was
bizarre-
and
I
can
just
imagine
on
a
friday
afternoon,
being
the
buckhead
with
all
the
traffic,
and
here
he
is
trying
to
get
more
pedestrian
friendly
stuff
going
on.
But
we
appreciate
your
work
and
thank
you
for
your
work
and
grant
congratulate
you
on
your
new
job
and
we'd
like
to
hear
from
you
and
hopefully,
you'll,
give
us
some
good
words
of
wisdom
for
the
future.
G
Well,
it
will
well,
mr
chairman,
first
of
all,
thank
you
so
much
charlie,
it's
been
such
a
pleasure
working
with
you
over
the
years
and
your
your
your
incredible
colleagues
on
the
planning.
Commission,
you
know
it's
it's.
It's
just
been
a
such
an
honor
to
to
be
not
just
with
this
department,
but
with
you
all
and
and
yes,
I'm
enjoying
the
the
last
bit
of
temperate
temperate
charleston
weather
before
we
head
off
to
the
the
rocky
mountains.
G
So
it's
great
to
be
with
you
and
and
for
you
and
for
all
your
your
fellow
planning
commission
members.
I
always
say
this,
but
I
really
mean
it.
Thank
you
for
everything
you
do
for
this
city.
This
city
is
a
great
place
to
live,
because
the
dedication
of
public
servants,
like
yourselves
so
thank
you
and
for
all
y'all,
I'm
not
going
away
forever.
I
got
my
phone
number
you
can
all
reach
out
to
me.
E
G
So
we
are,
we
are
making
progress
in
that
regard,
right,
okay,
so
what
I
think
what
I
think
we're
all
here
to
do
today,
first
of
all,
is
is
obviously
for
me
to
just
say
thanks
to
you
all,
as
I'm
on
my
way
out
to
boulder.
But
second,
I
wanted
to
give
you
all
just
a
few
thoughts
in
regards
to
the
comprehensive
plan.
G
I
wanted
to
offer
you
all
some
parting
thoughts,
one
of
the
one
of
the
wonderful
things
about
being
at
the
end
of
your
tenure
and
a
job
is
that
you
can
say
whatever
you
need
to
say,
and
I've
always
felt
the
liberty
to
do
that,
but
in
this
case
a
few
key
thoughts
as
I'm
on
my
way
out
to
boulder
this.
You
all
know
this.
G
With
some
of
the
best
people
from
around
the
world,
that
means
working
with
wagner
and
ball
working
with
the
the
water
institute,
working
with
our
incredible
housing
consultants,
who
are
using
a
whole
host
of
world-class
techniques
that
you're
gonna,
see
to
give
us
insights
into
what's
happening
in
this
place.
Insights
that
we
never
had
before,
and
the
biggest
takeaway
that
we're
seeing
right
now
from
all
this
work
in
the
words
of
the
brilliant
chris
from
morgan,
is
that
when
it
comes
to
the
future
of
our
city
business
as
usual,
just
can't
continue.
G
G
What
you're
going
to
see
is
that
sea
level
rise
and
climate
change
are
going
to
reshape
the
city
and
you're
going
to
see
that
people
in
our
city
are
burdened
by
housing,
we're
going
to
have
to
figure
out
how
to
help
keep
people
in
their
homes,
how
to
add
more
housing
stock
and
how
to
connect
it
all
together
in
a
way
that
helps
people
get
around
without
having
total
gridlock
and
decreasing
quality
of
life.
That
puzzle
can
be
intimidating
at
first,
and
this
is
the
key
concept
here.
G
G
G
G
What's
the
worst
case
scenario,
the
worst
case
scenario
looks
a
lot
like
new
orleans.
Today,
let's
say
sea
level
rise
speeds
up.
Let's
say
climate
change
gets
worse
and
we're
getting
hit
by
hurricanes
on
a
regular
basis.
Let's
say
that
we've
got
a
retreat
from
certain
areas.
We
call
that
reserve
certain
areas
for
sea
level
rise
and
the
whole
thing
is
propped
up
by
crumbling
infrastructure
behind
barriers.
Some
areas
under
sea
level
that
scenario
for
us
is
like
new
orleans.
Today:
it's
not
optimal,
but
it's
manageable.
G
Now,
there's
a
best
case
scenario
too,
and
that's
a
scenario
where
we
reserve
areas
where
the
climate
is
changing,
places
where
we
shouldn't
be
building,
we
say:
don't
build
there.
We
reallocate
growth
to
areas
where
it's
good
to
grow
places
like
k,
noise,
sam
rittenburg,
the
maybank
ridge
places
where
we
know
the
growth
is
good
laurel
island.
G
We
reconnect
all
those
places
with
great
transportation
infrastructure
and
we
build
the
right
kinds
of
climate-proof
infrastructure
to
help
us
drainage
to
help
pump
water
out
barriers
that
are
actually
great
waterfronts
and
we
get
ready
and
climate
proof
the
city
adding
enough
housing
so
that
the
market
doesn't
go
crazy
and
people
can
keep
living
here.
That
scenario
is
real
too,
and
in
that
condition
we
preserve
our
quality
of
life.
We
even
enhance.
G
It
but
it's
going
to
require
a
lot
of
work
on
everybody's
part.
Both
of
those
things
are
likely
in
my
mind
and
possible,
depending
on
the
choices
that
you
all
make
and
the
choices
that
our
elected
officials
make,
and
hopefully
this
plan
is
going
to
give
you
the
tools
to
consider
those
choices
and
plan
for
the
future
of
the
city.
G
So
I'm
going
to
be
quiet,
I'm
going
to
get
off
my
soapbox.
I
hope
that's
not
too
dramatic,
but
I
think
it's
real
and
I
think
that
you
all
are
the
best
qualified
people
to
consider
these
options
as
we
go
forward.
So
with
that
said,
I'll,
be
quiet
I'll.
Let
y'all
get
some
great
info
and
I'll
I'll
take
a
question
if
you
want
to
otherwise
I
will
sign
off.
H
Thank
you
jacob
for
all
of
your
guidance
during
this
time.
You
have
a
fresh
perspective,
a
young
perspective.
I
think
that's
what's
most
important
for
us.
A
lot
of
us
have
been
here
a
long
time
and
I
think
new
and
fresh
words.
I
have
a
lot
of
family
and
friends
in
colorado,
some
in
boulder,
so
you're
going
to
enjoy
that
state.
H
It's
a
very,
very
much
different,
and,
oddly
enough,
during
my
studies
for
this
comp
plan,
I
read
the
the
new
comp
plan
for
colorado
springs
because
I
thought
it
was
kind
of
a
completely
different
thing.
So
it's
kind
of
you
know
funny
that
you're
moving
to
colorado.
Now
after
I
read
that
we
will
miss
you
and
thank
you
for
your
guidance,
and
you
know
we
might
pick
up.
We
might
pick
up
that
phone
sometime,
so
safe
travels.
I
Yes,
I'd
like
to
just
say
it
reiterate
what
everybody
else
has
said:
jacob
you've
been
a
breath
of
fresh
air
and
it's
been
wonderful
to
have
you
on
the
commission.
I've
been
on
this
commission
a
long
time
and
I've
seen
a
lot
of
a
lot
of
directors
come
and
go
and,
and
it's
been
delightful
working
with
you
and
I'm
envious
of
you
moving
to
colorado,
but
we're
certainly
going
to
miss
you
here
and
good
luck
to
you.
B
Mr
chairman
yeah
I'd
like
to
say
you
know
jacob.
I
have
already
talked,
but
I'd
like
to
say
publicly
how
grateful
I
am
for
jacob's
friendship
and
and
for
all
these
years,
we've
jacob,
and
I
have
worked
together
in
lots
of
different
capacities
over
two
decades
now
and
and
I'm
just
grateful
for
all
the
things
he's
done
for
our
city
and
for
for
the
city
of
charleston,
and
I
know
he's
gonna
do
great
things
in
colorado
and
I-
and
I
know
this
is
not
goodbye.
E
D
So
we're
going
to
move
into
a
brief
update
from
chloe
steuber
on
our
engagement
with
the
public
on
the
plan
and
then
we'll
move
on
to
from
that
to
our
housing
consultants
and
then
to
our
water
and
land
use
consultants
and
then
we'll
have
some
public
comment.
As
you
can
see
from
the
agenda
here
chloe,
you
want
to
give
us
a
brief
update.
A
Yes,
I
will
bless
through
this
so
that
we
have
time
for
our
the
updates
about
the
housing
analysis
and
water.
Land
use
analysis,
and
I
know
andy
presenting
the
water
and
land
use.
Analysis
says
need
to
leave
at
4
30.
So
I'm
going
to
try
and
keep
this
quick
engagement
updates
over
300
participants
in
city-led
virtual
listening
sessions.
We
had
a
spanish
language
listening
session
on
the
charleston
ikea
salmo's
facebook
page.
It
was
live
streamed
and
then
it's
since
been
viewed
over
a
thousand
times.
A
So
that's
getting
great
coverage.
We've
had
over
200
participants
in
community-led
meetings
and
they're
more
scheduled
for
this
month.
So
we
expect
that
number
to
increase
we're
close
to
getting
2
000
survey
responses
online
survey.
We
have
200
printed
surveys
that
are
out
being
distributed
now
and
that's
that
total
includes
both
the
english
and
spanish
survey
responses,
950
flyers,
300
postcards
and
then
our
website
has
been
getting
good
traction.
We've
had
7
700
unique
views,
so
those
are
just
some
quick
stats
and
this
top
picture
here
is
artpot
volunteers.
A
This
is
the
community
organization
that
we
partnered
with
to
help
with
spanish
language
outreach.
They
did
a
community
walk
last
week
on
john's
island,
passing
out
surveys
and
getting
the
word
out
about
the
city
plans.
This
is
a
group
photo
of
them
and,
and
then
the
bottom
photo
there
is
the
charlie
come
on
held
on
facebook
in
early
october,
just
a
quick
update
on
where
we
are
in
the
overall
engagement
schedule.
A
So
we
have
extended
the
deadline
for
sir
to
complete
the
survey
and
to
submit
meeting
notes
from
community-led
meetings,
so
that
deadline
is
now
november
16th
and
at
this
point,
we're
going
to
be
moving
in
to
we're
closing
out
the
sort
of
input
gathering
stage
and
and
going
into
drafting
the
plan.
But
during
this
time
we're
not
going
to
stop
engagement,
we're
going
to
continue
engagement
through
the
city
plan,
blog
sharing,
updates,
findings
and
topic,
specific
learning
material
just
to
you
know,
keep
there's
still
plenty
of
opportunities
for
us
to
keep
people
informed
about.
A
What's
going
on
with
the
plan,
what
we're
learning
and
sharing
other
material
as
well.
If
people
want
to
dive
deeper,
we
have
our
for
the
first
city
plan,
blog
post,
we'll
have
a
farewell
letter
from
jacob,
and
also
you
can
already
watch
this
now
on
the
community
solutions.
Consulting
facebook,
page
or
the
city
plan
youtube
page,
a
short
15-minute
interview
with
jacob
and
our
consultant
aj
davis
about
the
city
plan
and
the
importance
of
getting
involved
and
some
some
farewell
reflections
from
him.
So
that's
those
are
those
updates.
Any
questions.
H
These
community-led
meetings
are
on
your
engagement
schedules.
Those
are
things
like
the
preservation
society
in
the
center
for
hairs,
property
and
stuff.
Like
that
right,
I
attended
the
preservation
society
coastal
conservation
week,
one
and
then
several
of
the
ones
that
y'all
did
and
I'm
really
noticing
a
thought
process
based
on
demographics
that
are
there,
and
I
just
want
to
make
sure
that
you
all
feel
we're
getting
that.
I
know
that
our
our
consultants
are
really
hard
on
the
ground.
Are
they
do
they
feel
like
they're?
Getting
good
responses
and
good
information
do
y'all?
H
A
Fatika,
aj
and
eric
are
doing
targeted,
outreach
to
different
groups
to
host
those
to
try
and
address
some
of
those
gaps
in
demographics,
and
they
have
been
very
clear
and
that
that
is
a
challenge
that
we're
not
going
to
necessarily
be
able
to
overcome.
With
this
one
engagement
push
that
that's
going
to
take
some,
some
of
some
of
that
some
of
those
gaps
in
participation
is
going
to
take
a
longer
more
con.
A
You
know
ongoing
relationship,
building
and
sort
of
rebuilding
of
trust
that
has
been
lost
in
the
past
so
but
they
are
going
to
in
december
at
the
end
of
this
year,
we'll
have
a
report
from
them
that
will
you
show
us
what
representation
we
did
get
through
through
these
efforts,
which
have
been
multifaceted,
and
you
know,
as
you
said,
they've
been
out
and
out
in
the
community
pounding
pounding
the
pavement
we've.
You
know.
A
We've
really
used
our
full
tool
kit
at
our
disposal,
even
with
the
pandemic,
but
even
with
that
we're
gonna.
We
know
that
we're
gonna
fall
short
with
some
demographics
and
so
they're
going
to
present
us
with
what
we
did
get
and
some
recommendations
for
how
we
can
move
forward
addressing
those
gaps.
So,
yes,
we're
we're
we're
seeing
as
good
of
representation
as
we
could
have
hoped
for,
given
everything
but
there's
definitely
so
still
more
work
to
be
done.
H
I
guess
where
I'm
going
is.
I
don't
want
issues
to
appear
weighted
just
because
we
didn't
hear
from
a
group
and
and
the
reason
I'm
saying
that
is
I've
attended
many
boards
and
even
the
planning
commission
for
years.
You
know
representing
something
and
have
heard
like
there's
nobody
here
from
that
neighborhood,
so
they
must
not
be
concerned
and
that's
not
necessarily
an
immediate
translation.
H
So
I
just
want
to
even
even
one
person
telling
us
that
there's
an
issue
we
might
want
to
really
dig
into
the
issue
just
because
we
haven't
reached
the
other
999
people
that
might
have
the
same
issue.
I
just
that
really
caught
me
in
the
last
couple
of
sessions
that
I've
been.
So
I
just
wanted
to
make
sure
that
we
all
keep
an
open
mind
about
that
as
we
move
forward.
E
H
E
D
J
I'm
here
and
I
both
here
actually
hi
everyone.
My
name
is
remy
beveridge
and
with
me,
anna
is
somewhere.
Anna
tapp
is
our
lead
data
scientist
and
we're
with
community
data
platforms.
So
here
I
am
anna.
If
you
want
to
wave
everybody
nice
to
meet
you
guys,
I
am
going
to
start
sharing
and
then
we
will
get
moving
on
our
presentation.
J
J
J
J
We
also
have
a
wonderful
team
of
data
scientists
and
statisticians,
so
we
apply
expert
knowledge
of
those
two
fields
ensuring
the
validity
of
the
data,
provided
we
have
a
really
extensive,
qa
process,
so
we
aren't
going
to
give
you
something
that
we
aren't
confident
in
and
then.
Thirdly,
we
craft
visualizations
that
illustrate
housing
in
ways
that
are
useful
for
planning
decisions.
J
J
It's
it's
great
that
you
have
this
spreadsheet
or
something,
and
so
what
cdp
really
prides
itself
in
is
that
we
are
able
to
give
visualizations
and
we're
able
to
give
different
pieces
of
information
that
are
really
going
to
be
helpful
as
y'all
are
making
this
comprehensive
plan
and,
as
you
all
are
making
decisions,
we
also
want
to
talk
a
little
bit
about
what
charleston
had
asked
of
cbp.
So
one
of
those
things
was
to
collect
and
map
current
and
pass
costs
to
buy
and
rent
in
the
city
at
a
parcel
level.
J
Another
thing
was
to
collect
attributes
related
to
the
housing
type,
such
as
number
of
bedrooms,
the
units
per
building
and
demographics,
and
this
is
something
else
that
cdp
has
leverage
on
is
that
we
have
aggregated
demographic
data
that
we're
able
to
show
the
city,
so
you
guys
can
see
patterns
and
different
things
that
are
happening
and
then,
like
I
mentioned,
we
have
this
craft
visualization
point
and
the
create
data.
Visualization
point
are
really
similar.
J
We
want
this
data
to
be
visualized
in
a
way
that
number
one
you
as
planning
commissioners
can
make
a
decision,
but
secondly,
we
want
it
to
serve
multi-purposes,
as
we
are
show,
as
you
guys
show
different
community
members
and
different
stakeholders,
these
things
too.
We
we
don't
want
it
to
just
be
planning
focus.
We
also
want
it
to
tell
stories.
We
want
to
tell
the
story
of
the
changing
city.
We
want
to
tell
the
story
of
housing
and
transportation
cost
burdenness,
which
all
of
those
we'll
continue
to
talk
about
later.
J
J
The
valuations
listed
here
so
the
home
valuations,
the
rental
valuations
and
the
historical
valuations
which
we
created
using
machine
learning
and
if
that's
a
term,
that's
not
really
familiar
we'll
go
into
a
little
bit
more
of
what
that
means.
In
a
later
slide,
we
will
also
be
delivering
a
method
summary,
which
will
just
be
an
explanation
into
some
of
the
more
technical
things
that
we
did
and
how
we
leverage
different
data
and
some
more
of
these
kind
of
fancy
machine
learning
words.
Those
will
be
explained
and
and
gone
over
in
that
method.
J
Summary
then,
as
I
said
earlier,
we
have
three
visualizations
that
we'll
be
delivering
to
the
city,
the
first
in
affordability,
analysis,
the
second,
a
housing
and
transportation
analysis
and
third,
a
neighborhood
analysis
or
a
changing
city,
we've
kind
of
gone
back
and
forth
on
the
name.
So
if
it's
changing
city
or
neighborhood
analysis,
it's
referring
to
the
same
thing
next,
I
think
it's
really
important
that
we
talk
about
some
of
cdp's
process.
J
I
don't
live
in
charleston,
neither
does
anyone
on
our
team,
and
so
we
don't
want
to
just
come
in
and
not
understand
the
community.
Obviously
you
guys
do,
and
this
is
home,
and
so
we
wanted
to
do
our
best
to
understand
the
process
that
we
are
jumping
into,
and
so
what
cdp
does
is
we
have
many
stakeholder
interviews,
and
so
we
had
interviews
with
developers
with
community
organizations
with
real
estate
professionals,
housing
agencies
and
professionals.
J
We
had
input
from
all
of
this
a
lot
of
the
sessions
that
chloe
just
mentioned,
specifically
the
housing
labs.
So
we
listen
to
residents.
We
also
have
team
collaboration,
chloe,
jim
and
my
team,
and
I
we
meet
twice
a
week
and
go
through
all
of
these
different
things,
and
so
you
guys
are
our
boots
on
the
ground,
as
chloe
said
that
there's
people
running
all
over
and
handing
out
surveys.
J
You
are
our
boots
on
the
ground,
and
so
we
also
collab
with
housing
staff
and
with
people
on
the
gis
team,
and
then
we
also
wanted
to
discuss
a
little
bit
of
our
data,
and
so
we
leveraged
data
from
the
gis
and
assessors
department
from
charleston
city
from
berkeley
county
from
charleston
county.
We
also
use
a
lot
of
our
own
commercial
data
which
pulls
from
commercial
listings.
We
also
for
the
housing
and
transportation
analysis.
We
use
charleston's
placer
data
and
we
also
use
census
data
next.
J
Here
is
that
machine
learning
slide
that
I
promised,
and
so
the
definition
of
machine
learning
is
we
use
technology
to
create
data,
that's
not
readily
available
through
predictive
formulas
and
algorithms,
and
some
of
our
examples
of
what,
if
you
can
think
about
it,
we
input
data.
We
train
it
through
these
predictive
algorithms
and
these
formulas,
and
then
we
have
an
output,
and
so
what
our
outputs
were
are
the
home
valuations,
the
rent,
valuations
and
the
historical
evaluations.
J
J
So
what
we
web
script
was
a
lot
of
multi-family
apartment,
complex
data,
so
their
bedrooms
available
their
pricing.
We
also
web
scraped,
the
advertised
homes
for
sale
and
why
these
are
really
important
for
the
home
valuations,
and
the
rental
analysis
is
that
these
are
the
best
market
indicators,
the
advertised
sales
and
the
advertise.
The
advertised
home
for
sales
and
multi-family
apartments
for
a
sale
are
the
best
indicators
of
the
current
market.
We
also
use
flood-related
data,
so
we
use
the
fema
floodplains.
J
J
This
is
the
most
predictive
subset
that
we
could
create,
and
so
that
happens
over
and
over
and
over
again,
and
so
our
team
decided
that
the
xgboost
model
was
the
most
predictive
and
the
most
accurate,
and
so
they
used
that
for
the
home
valuations
and
then,
like,
I
said,
our
outputs,
we
will
have
the
home
valuations,
the
rental
valuations
and
the
historical
valuations
doing
it.
This
way
also
allows
for
some
ground
truth,
and
so
it
allows
some
of
the
planning
department
to
go
through
and
say.
Okay,
this
totally
makes
sense.
J
We
can
see
that
this
house
in
this
area
and
this
neighborhood,
that
it
matches
that
this
is
what
that
looks
like,
and
so
it's
not
just
people
coming
in
from
all
over
the
country,
as
our
team
is
I'm
currently
in
michigan,
but
I
also
have
colorado
connections.
I'm
about
home,
for
me,
is
about
two
hours,
west
of
denver
and
boulder,
and
so
we
have
people
that
can
go
ground
truth
all
of
this
information.
J
So
we
know
that
the
city
wants
to
understand
who
is
class
burdened
and
where
do
these
people
live?
We
know
that
you
want
to
know
what
type
of
homes
that
these
people
who
are
cost
burdened,
what
type
of
homes
do
they
need,
and
then
third,
where
does
the
current
zoning
allow
for
these
homes
to
be
built?
J
And
so
I
think
that
these
questions
really
set
up
the
actionable
steps
that
this
visualization
will
allow
you
all
to
take,
because
it
would
be
great
if
we
could
say
okay.
This
amount
of
people
are
cost
burdened
in
charleston,
but
if
you
don't
know
where
they
live,
how
can
you
help
them
and
then,
even
if
you
do
know
where
they
live,
what
kind
of
housing
do
they
need?
J
So
those
two
groups
of
people,
the
one
single
person
in
the
family-
they
need
completely
different
housing
and
appropriate
and
affordable
housing
for
a
single
person
looks
completely
different
than
for
this
family
of
four.
So
we
also
need
to
know
who's
cost
burden.
Where
do
they
live
and
then
what
types
of
homes
are
going
to
be
appropriate
for
them?
J
Next,
we
want
to
talk
about
the
housing
and
transportation
visualization,
so
to
be
clear
right
here.
This
is
a
mock-up.
It
doesn't
display
real
data
and
it
will,
but
it
doesn't
right
now,
and
so
we
have
these
three
different
sections.
We
know
we
have
cost
burden,
non-cost
burden
and
severely
cost
burden
and
the
reason
for
doing
a
deep
dive
into
the
housing
and
transportation
visualization
was
to
get
a
fuller
picture
of
cost
furtherness
in
the
city.
J
Then
our
final
visualization
is
this
neighborhood
analysis,
visualization,
and
so
we
have
spent
we've
had
many
conversation
conversations
with
jim
and
chloe
talking
about
the
importance
of
telling
the
story
of
gentrification
within
the
city
of
charleston,
and
so
we
really
landed
on
three
different
pieces
that
we
wanted
to
talk
about.
We
want
education
to
be
a
part
of
this.
We
want
the
residents
and
the
community
members
to
be
able
to
learn
about
the
different
factors
that
do
influence
gentrification
and
really
understand
how
those
play
a
role.
J
We
also
wanted
to
give
a
neighborhood
profile
so
that
people
would
be
able
to
say.
Okay.
Where
does
my
neighborhood
stand?
Where
how
are
we
doing,
and
so
there
will
be
a
neighborhood
profile
part
where
all
of
these
different
factors,
demographics,
housing
costs,
permits,
property
value
and
the
change
from
residential
to
commercial?
They
will
be
able
to
see
how
their
neighborhood
has
changed
over
time
did.
Has
there
have
their
housing
costs
rised
risen?
Have
their
permits
gone
up?
J
Has
the
property
have
the
value
property
values
increased
and
then
displacement
risk
will
actually
be
called
priority
areas
and
we
will
be
able
to
see
the
different
neighborhoods
that
are
a
priority
area
for
displacement
and
just
to
give
a
little
bit
more
insight
into
the
process
of
how
we've
come
up
with
what
this
will
look
like.
It's
been
a
really
collaborative
effort
between
our
team
and
jim
and
chloe,
along
with
other
housing
and
planning
staff
members,
and
we
also
came-
we
started.
H
Well,
I
I
think
she
may
have
answered
it,
but
I
wanted
to
review
because
they
were
talking
about
taking
all
the
data
putting
in
an
algorithm
and
getting
out
an
answer
for
us
and
then
putting
it
in
a
graphic
form
that
we
can
use
to
understand
it
to
make
policy.
And
I
think
she
used
the
term
ground
truths.
H
F
Can
I
answer
that
remy
yeah
yeah,
so
anna
here?
What
we
do
when
we
create
a
machine
learning
algorithm?
Is
we
don't
use
all
the
data
to
train
the
algorithm?
We
hold
out
data,
so
that's
the
primary
source
of
ground
truthing.
Is
that
a
bunch
of
recent
sales
we
did
not
put
into
the
process
of
the
algorithm
we
held
it
out
and
then
we
go
back
and
we
look
at
that.
F
You
know
those
holdouts
and
we
compare
it
to
the
output
of
the
algorithm
to
see
whether
it
did
a
really
good
job
or
not
of
predicting
those,
and
we
keep
on
going
back
and
we
keep
on
going
back
until
that's
right
and
another
technique.
That's
often
used
is
that
hold
out
group.
It's
not
always
the
same
group
every
time.
So
you
might.
F
H
F
Yeah,
so
you
have
that
group
and
you
say:
okay:
this
is
our
truth
right.
This
is
our
ground
truth,
like
these
houses
actually
sold
for
this,
but
we
didn't
use
that
information
to
train
the
algorithm.
So
you
create
like
an
error
assessment,
so
you
compare
what
the
algorithm
produced
against
that
they
call
it
the
test
data
set
and
then
you'll
do
that
a
few
times
with
some
different
test
data
set.
And
then
you
know,
your
algorithm
is
very
good
and.
F
H
I'm
just
curious
because
it's
definitely
I
mean
this
isn't
the
first
time
I've
seen
this
I've
seen
this
done
for
other
things
and
it's
definitely
the
way
of
the
future.
You
just
want
to
make
sure
that
when
you
build
that
algorithm
and
you
get
an
answer-
you
really
know
you
got
the
answer
and
I
just
want
to
understand
how
that's
happening.
So.
Thank
you
understand.
J
Just
one
other
thing
I
think
I'd
like
to
throw
in
was
that
our
team
actually
was
really
really
diligent
in
what
they
did
so
much
so
is
they
wanted
to
create
different
subsets
to
make
sure
that
they
were
getting
the
entire
picture,
and
so
they
they
created
different
algorithms.
That
then
matched
together
for
the
county
for
the
city
for
the
municipality,
depending
on
where
those
different
subsets
were,
and
so
there
was
just
a
lot
of
detail
and
a
lot
of
again
iterations.
E
D
Well,
then
I
thank
you
all
so
much
and
excellent
info
there
and
everybody
is
ready
to
go
back
to
their
stats
classes
now,
after
all,
that
too,
I
know
it
brings
back
my
memories
of
stats
class,
so
we
have
now
andy
stranad
with
wagner
and
ball,
to
give
us
some
new
info
from
our
water
and
land
use.
Consultants.
C
C
C
Some
of
this
is
can
be
tailored
for
a
public
explanation
and
should
be
made
public,
I
think,
but
but
it
really
is
geared
towards
towards
the
planning
department.
So
this
is
how
we
see
our
work,
plugging
in
kind
of
at
a
base
layer,
the
land
and
water
analysis
below
the
typical,
the
other
more
conventional.
I
guess
elements
of
the
comp
plan.
C
Knowing
how
how
you
relate
to
sea
level
and
the
other
land
levels
around
you,
then
we've
applied
your
watershed
impact
so
how
any
one
particular
property
impacts
the
properties
around
it,
based
on
its
location
upstream,
downstream
et
cetera.
How
rainfall
and
tide
create
those
relationships
between
properties
and
then,
finally,
we
did
an
environmental
overlay.
C
So
we
looked
at
other
ecological
considerations,
especially
on
higher
ground
and
at
the
very
low
fringes
that
should
have
a
special
consideration.
Things
like
marsh
migration
at
the
edges,
the
at
the
water's
edge
and
some
special
high
ground
characteristics
like
forests,
existing
forests
and
tree
cover
that
should
be
that
provide
an
additional
ecological
benefit.
C
C
C
That's
also
an
area
that
has
the
most
potential,
maybe
the
most
risk,
but
also
the
most
potential
to
adapt
over
time
and
then
there's
a
high
ground,
relatively
small
portion
of
the
city,
that's
less
impacted
by
rainfall,
flooding
or
storm
surge.
This
is
kind
of
the
upper
bound
of
storm
surge
across
the
city
as
well,
and
there
are
various
things
you
can
do
projected
to
do
across
these
zones.
C
C
Overlaying
on
these
elevation
zones
is
vulnerability.
Watershed
size,
kind
of
extent
of
tide,
which
sometimes
extends
quite
far.
Inland
vulnerability
has
to
is
really
important
here.
That
has
to
do
with
how
many
properties
are
downstream
from
you
so
who
your
runoff
is
impacting
and
then,
like,
I
said,
some
environmental,
overlays,
ecology
and
importantly,
soils.
One
thing
we
find
is
the
best
soils
for
water
infiltration
are
the
highest
up
in
the
watersheds,
which
is
important,
important
opportunity.
C
C
C
Looked
at
the
rainfall
rainfall
rate,
prediction
kind
of
a
storm
surge
elevation,
which
is
the
maximum
kind
of
worst
case
scenario
for
a
category
three
17
feet
and
then
overlaid.
A
sea
level
rise
projection,
also
a
gradient
nothing
set
in
stone
and
that
those
data
inputs
resulted
in
the
elevation
zones
so,
like
I
was
describing
before
tidal
risk
zone,
an
adapt
zone,
a
portion
of
which
is
subject
to
compound
flooding.
C
That's
the
zone
where
you
have
rainfall
from
above
and
tied
from
below
interacting
the
top
of
the
adapt
zone,
is
more
or
less
equivalent
to
storm
surge
risk.
And
then
you
have
the
high
ground,
which
is
relatively
safe
outside
of
the
100
year
floodplain
and
above
category
3
storm
surge,
as
you
play
that
out
across
the
city.
You
see
that
there's
not
that
much
green,
relatively
and
a
lot
of
it
is
outside
the
urban
growth
boundary
we'll
get
to
some
of
those.
What
that
means
a
little
bit
more.
C
So
those
two
types
of
properties
together
generate
the
it's
a
property's
risk
and
we
analyze
that
in
relation
to
other
properties
within
the
watershed,
and
we
resulted
at
this
map.
So
this
is
a
kind
of
that
familiar
zone,
tidal
risk
zone,
adapt
and
high
ground,
but
it's
now
split
into
low
impact
and
high
impact.
C
C
So,
for
example,
this
dark
green
is
high
ground
low
impact.
That's
what
you
might
consider
the
safest
lowest
impact
place
for
development,
whereas,
whereas
this
next
lightest
screen
indicates
that
well,
that's
still
high
ground
property
in
that
zone
has
more
impact
on
the
downstream
watershed
beneath
it.
C
C
C
C
C
C
So
that's
promising,
I
think,
but
you
see
especially,
for
example,
areas
of
cane
hoy,
which
which
are
projected
to
experience
some
of
this
marsh
migration.
It
would
be.
It
would
be
wise,
for
example,
in
areas
like
that
to
consider
the
benefits
of
protecting
marsh
and
protecting
where
that
marsh
might
go
in
terms
of
storm
surge,
buffering,
storm
water
sinks.
Things
like
that
again,
not
to
say
that
anything
is
off
limits
per
se,
I'm
just
that
certain
special
characteristics
should
be
taken
into
account.
C
C
Tree
canopy
is
especially
important,
for
example,
moving
up
towards
francis
marion.
The
high
ground
covered
in
forest
here
is
limiting
the
impact
on
the
properties
below
it
kind
of
the
lower
the
lower
elevation
areas
of
canehoy.
That's
an
important
relationship
to
consider
as
development
is
projected
there,
a
similar
condition
in
the
maybank
corridor.
C
And
finally,
a
soils
overlay,
so
here
you
see
in
green
these
hydrologic
group,
a
soils
that
absorb
the
most
potentially
absorbed
the
most
stormwater
runoff.
Those
are
the
sandy
soils.
Those
high
beach
ridges
correspond
in
many
cases
to
higher
ground
and
as
we
move
down
towards
yellow
and
then
this
kind
of
beige
color
soil
is
less
inclined
to
absorb
water.
More
inclined
to
run
off
to
your.

Any
questions,
commercial
members-
if
not,
I
guess
we're
good,
and
we
appreciate
the
information
we
know
there's
a
lot
of
slides
and
I'm
sure
these
will
be
available
to
us.
If
I
wanted
to
look
at
this
some
of
this
stuff
later,
will
you
share
some
of
this?
So
I
can
pull
it
up
later
on
or
anything
like
that.
E
If
there
yet
they'll
share
that
with
the
commission
members,
we
greatly
appreciate
it
and
thank
you
for
your
work
and
for
your
information,
we'd
love
to
hear
from
you
again.
You
know.
If
there's
no
questions.
Mr
morgan,
I
I
think
we
have.
Is
there
a
correspondence
or
a
public?
So
I
guess
that's
where
we're
at.
K
Great
good
afternoon,
it's
kashan
draulay
with
historic
charleston
foundation.
I
just
wanted
to
say
thank
you
to
the
planning
commissioners
for
your
focus
on
the
city
plan
and
and
starting
from
scratch,
and
really
focusing
in
on
the
issues
of
housing
and
climate
change.
Charleston
has
changed
dramatically
in
the
last
10
years,
since
a
full,
comprehensive
plan
was
worked
on
in
the
century.
K
K
Hcf
looks
forward
to
sending
the
planning,
commission
and
planning
staff
our
final
thoughts
and
recommendations
on
the
city
plan
and
those
thoughts
will
mainly
be
focused
on
the
natural
resources,
cultural
resources,
land
use
and
resiliency
elements
of
the
plan.
Thank
you
for
this
opportunity
to
be
involved
and
we
look
forward
to
working
with
you
all.
E
I
D
We
hope
to
ultimately
have
a
full
draft
of
the
plan
by
late
january
early
february
and
then
begin
meetings
between
you
all
and
ultimately
city
council
and
then
get
it
to
city
council
by
march,
as
a
draft
that
that
is
the
tentative
schedule
right
now,
it's
shifted
a
little
bit
as
we've.
You
know
I've
seen
the
enormous
level
of
work
we
have
ahead
of
us.
