If this is YOUR meeting, an easy way to fix this is to add a description to your video, wherever mtngs.io found it (probably YouTube).
A
All
right
we'll
go
and
get
started
here.
It's
it's
603.
welcome
everybody.
My
name
is
steve
nabor,
I'm
the
city
engineer
for
the
city
of
des
moines.
I've
got
a
number
of
team
members
with
me,
including
craig
bushka,
who
is
the
project
engineer
for
the
levy
project?
I've
also
got
mark
lan
with
schneider
associates.
A
He
is
the
project
manager
for
the
what's
actually
the
the
icon
now
known
as
the
iowa
confluence
water
trails,
project
and
and
so
we're
presenting
these
together,
because
they
actually
have
been
coordinated
together
while
they're
a
separate
construction
contract
there'll
be
separate
construction
contracts.
A
A
So
so
so
that's
the
point
of
our
meeting
tonight
is
to
touch
on
on
those
two
projects
and
when
their
schedules
and
timing,
what
is
actually
going
to
occur,
and
so
here
you
can
see
a
photo.
This
is
actually
levy,
work,
that's
being
done
on
the
first
phase
of
the
levee
alterations
if
you've
seen
some
of
the
light
blue
trucks
with
corel
contracting
on
them
up
and
down
the
river
on
the
des
moines
river
north
of
the
confluence
upstream
of
the
confluence
you
may
have.
That
is
actually
phased.
A
The
first
phase
of
the
of
the
major
phase
of
the
levee
alterations
project.
So
this
is
a
photo
of
that
work
of
the
levy
project,
so
some
attendee
instructions
we're
running
this
meeting.
You
know
similar
to
other
city
meetings
in
the
past.
Hopefully,
if
you're
on
a
computer
or
smart
device,
you
see
a
menu
bar
like
this,
as
shown
on
the
bottom
of
your
screen.
A
If
you
click
on
the
participants
icon,
you
can
that'll
give
you
some
tools
where
you
can
raise
your
hand,
lower
your
hand,
and
that
way
we
can
kind
of
keep
the
meeting
in
order
early
fashion
and
respond
to
questions
and
whatnot.
So
craig
and
I
are
going
to
give
a
quick
presentation
of
what
of
the
staging
of
the
projects
and
then
then
we'll
have
a
pause
at
the
end
for
for
questions
and
and
comments,
and
so,
if
you're
on
a
phone,
I'm
not
seeing
anybody
on
a
phone.
A
But
if
you
are
on
a
phone
press
star
nine
to
raise
your
hand
and
to
mute
or
unmute
yourself
press
star
six
otherwise,
like
I
said,
if
you're
on
a
smart
device
or
computer,
you
see
this
participants
tab.
That
should
give
you
the
tools
to
raise
your
hand
and
mute
yourself
that
sort
of
thing
we
are
recording
this
meeting.
That's
that's
a
big
benefit
of
us
doing
these
meetings
virtually
we
can
record
them
and
we'll
actually
post
them
on
our
website.
A
So
if,
if
you
have
neighbors
or
friends
or
family
or
fo,
folks
that
colleagues,
that
that
didn't
get
a
chance
to
attend
tonight,
they
can
actually
watch
this.
You
know
this
meeting
as
it's
being
recorded.
A
So
we're
here
to
talk
tonight
again
about
two
projects:
the
iowa
confluence,
water
trails,
scott
avenue
project,
the
scott
avenue
portion
of
the
project,
the
levy,
alterations,
phase
b
and
c,
so
essentially,
the
second
and
third
phases,
major
phases
of
the
levee
alterations
project
and
then
go
through
the
phasing
of
projects
and
then
ask
questions
and
again
this
is
a
photo.
Hopefully
maybe
you
recognize
this
area.
A
This
is
a
the
entrance
to
principal
park,
the
baseball
stadium
there,
and
so
there
are
levy
the
the
berms
that
you
see
in
fro
out
in
front
along
second
avenue,
though
that's
actually
these
are
actually
levees
and
so
that
those
levees
have
already
been
improved.
This
was
the
grading
that
was
done
earlier
this
summer
to
raise
those
levees
and-
and
so
we
are
so
that
that
was
actually
technically
phase
one.
So
again,
what
is
a
levy?
A
levy
is
a
man-made
structure.
A
Often
an
earthen
embankment,
designed
to
in
accordance
with
engineering
practices,
to
control,
contain
or
divert
the
flow
of
water,
providing
you
know,
reduced
flood
risk.
You
know
providing
that
protection
from
from
temporary
flooding.
Essentially,
it's
a
levee
is
a
barrier
that
keeps
the
flood
waters
from
flooding
adjacent
areas
that
are
lower
than
the
levee
and,
from
the
purposes
of
the
national
flood
insurance
program,
the
federal
emergency
management
agency,
otherwise
known
as
fema
they'll
they'll.
A
They
will
only
recognize
on
their
flood
hazard
and
risk
mapping
those
levee
systems
that
meet
and
continue
to
meet
correct
design
criteria
and
maintenance
criteria
that
are
consistent
with
their
their
certification
and
accreditation
requirements.
So
fema
will
accredit
a
levy
is
providing
adequate
risk
reduction
on
their
flood
insurance
rate
maps.
A
If
that
certification
and
the
adopted
operation
and
maintenance
plans
provided
by
the
levy
owners
are
confirmed
to
be
adequate
and
the
city
of
des
moines
is,
is
the
owner
of
the
the
levees
that
are
downtown
so
this,
and
this
does
impact
insurance
and
building
requirements.
Okay.
So
when
we
talk
about,
why
we're
doing
these
improvements,
it's
it's
to
meet,
we
need
one.
One
of
them
reasons
is
we
need
to
improve
the
levies
to
meet
the
the
the
latest,
the
the
accreditation
and
certification
requirements
of
of
fema
and
so
years
ago.
A
You
know,
I
think,
about
in
2011
that
the
u.s
army
corps
of
engineers
did
some
some
flood
from
some
modeling
of
the
rivers
and
determined
that
certain
events
are
more
likely
to
occur
more
frequently
higher.
You
know
higher
flows
higher
intensities
and
so
that
that
modeling
of
the
rivers
is
driving
the
need
for
improvements
to
the
levee
system,
and
so
again
our
goal
is
to
make
sure
one.
A
The
levees
one
provide
the
necessary
flood
risk
to
meet
the
fema
accreditation
requirements
which,
in
the
in
our
case
fema
typically
requires
the
levy
to
be
three
feet
above
what
is
known
as
the
100
year
flood
or
one
percent
annual
exceedance
probability
storm,
but
again,
mostly
known
as
the
100
year
storm
event.
So
we
want
to
meet
those
requirements.
A
We've
decided
to
actually
design
our
project
to
be
above
that,
so
we're
actually
meeting
two
higher
criteria.
We're
going
with
the
fema
requirement,
plus
six
inches
or
using
the
us
army
core,
has
a
design
requirement
for
the
hundred
year,
90
conditional
non-exceedance
elevation,
which
is
a
it's
a
probabilistic
chance.
That's
based
on
modeling
that
the
levee
will
ex
will
be
exceeded.
A
So
we're
actually
designing
this
project
to
be
above,
given
some
free
board
above
the
requirements
that
we
need
for
fema
and
so
again,
what
does
that
mean
in
a
lot
of
and
there's
a
number
of
cases
downtown
where
our
levees
are
only
two
two
feet
or
so
give
or
take
above
the
hundred
year?
Flood
elevation
well
fema
says
we
need
to
be
three
feet
for
the
most
part
and
in
some
areas
next
to
structures.
A
We
need
to
be
four
feet
above
so
again,
that's
where
it
requires
a
raise
of
the
levy
of
the
levee
system.
We've
also
done
a
number
of
testing
on
these
levees.
We
want
to
ensure
that
they
are
geotechnically,
sound
and
so
we've
taken
a
number
of
of
we
call
them
soil,
borings
or
samples
to
test.
Basically
the
stability
of
the
levees
and
model.
A
We
call
it
seepage-
or
you
know,
there's
water,
that
actually
groundwater,
that
flows
underneath
the
levees,
and
so
so
we
we're
we've
done
that
testing
with
the
levees
to
see
if
there
are
improvements,
geotechnically
that
need
to
be
done
to
the
levee
system
and
so
that
that's
kind
of
the
I
know
it's
a
lot
of
information,
that's
the
overview,
but
in
general,
we've
got
to
improve
our
levies
if
we
want
fema
to
continue
to
recognize
these
levees
as
accredited
levies
shown
as
moderate
risk.
A
On
the
you
know,
the
flood
insurance
rate
maps,
if
you
pull
up
a
flood
insurance
rate
map
for
these
areas,
that's
what
has
shown
moderate
risk
protected
by
levy
as
part
of
the
national
flood
insurance
program,
so
which
again
those
impact,
insurance
and
building
requirements
so
and
again
and
there's
that
requirement,
and
we
also
want
to
mitigate
and
reduce
flood
risk
as
well.
A
So
how
do
we
do
all
this
again?
I
just
threw
a
lot
at
you
here,
but
first,
let's
go
to
one
real,
quick,
the
iowa
confluence
water
trails,
scott
avenue
project
you
may
have
heard
about
this
in
the
news.
A
This
project
does
a
number
of
things,
one
it's
providing
an
incredible
recreational
feature
in
the
river
and
also
it's
it's
it's
in
modifying
the
dam
by
by
notching
the
dam
and
by
also
making
some
improvements
just
downstream
of
the
dam
to
control
the
drop
essentially
so
that
there's
not
that
vortech.
A
Maybe
that
is
maybe
the
right
word
vortech
feature
and
that's
the
problem
with
the
dams,
if
it
and
when
the
water
goes
over
the
dam,
it
creates
almost
kind
of
like
a
a
rolling
effect
kind
of
like
a
washing
machine
type
effect
where
the
water
just
kind
of
spins
in
a
vortex
manner,
and-
and
so
this
will
eliminate
that
that
hazard
and
as
well
as
instead
of
just
the
river
dropping
at
the
dam
they'll
be
set,
there'll
be
multiple
drops,
you
can
see
them
on
here,
drop
one
drop
two
and
and
also
create
a
recreational
type
course
for
for
river
users.
A
You
know
kayaks
and
whatnot,
and
also
even
creating
a
improving
it
for
fish
habitat,
creating
a
fish
passage
to
go
upstream
as
well,
and
you
can
see
in
the
picture
lower
in
the
lower
left
there.
You
also
some
improvements
along
the
bank
portage.
A
A
Here's
kind
of
a
rendering
graphic
showing
that
the
iowa
confluence
water
trails
has
created
a
website
iconwatertrails.com
if
you'd
like
to
find
out
more
so
again,
that's
a
quick
overview
of
what
the
project
is
so
again,
mitigating
the
dam
risk
and
and
then
also
providing
the
recreational
feature,
and
I
talked
about
all
the
the
needs
for
the
flood
protection
system,
the
levee
system
right.
So
so
this
is
a
big
project.
A
This
map
actually
shows
in
color
where
the
downtown
levees
are,
and
so
you
can
see,
there's
multiple
levees,
there's
one
on
there
on
each
side
of
the
river
and
phase
a
so
we've
broken
it
out
into
phases,
because
it's
a
massive
project
phase
a
has
already
been
under
construction.
A
That's
well
along
the
way
that
included
the
simon
s
amphitheater
if
you're
familiar
with
the
simonides
and
amphitheater
the
back
walls,
that's
the
seat,
walls,
that
is
a
flood
wall
actually,
and
so
we've
we've
raised
those
to
meet
the
fema
standard
and
then
we've
also
added
done
improvements
to
what
we
known
as
closure
improvements
where,
if
you
notice
there's
walkways
between
the
seat
walls
right
well,
you
know
to
to
get
down
to
the
concerts
and
nightfall
in
the
river
and
those
walkways
are
openings
right.
A
So
so
we
also
have
openings
or
closures
what
we
call
at
the
railroad
tracks
or
at
roadway
bridges
right
because
the
levees
up
here,
but
then
we
come
down
to
where
the
where
the
road
is
or
the
railroad
tracks
are.
So
those
are
what
we
call
closures
if
there
was
ever
and
when
a
high
water
event
at
certain
stages,
we
actually
have
to
come
and
close
those
openings.
So
the
areas
between
the
seat,
walls
we
put
in
notches
to
create,
stop
logs
and
close
those
openings,
and
that's
the
case
also
for
roadways.
A
Even
the
picture
I
showed
you
earlier
with
principal
park.
We'd
have
to
close
over
the
entrance
way
to
the
parking
lot
between
the
levy,
the
two
levy,
the
levy
opening
there
and
then
we've
also
done
some
levy
raises.
So
again,
that's
shown
in
green
here
in
phase
a
that
that
project's
already
nearly
nearing
completion,
so
we're
here
tonight
to
talk
about
phases
b,
going
up
the
raccoon
river
and
phase
c
shown
in
pink
here.
Okay,
so
those
are
the
two
phases
we're
here
to
talk
about
tonight.
There
are
future
phases
going
downstream.
A
In
fact,
all
the
way
down
the
river
and
around
up
and
around
four
mile
creek
is
the
levee
system.
We've
got
to
improve
all
that
because
it's
all
hydraulically
connected
right.
If
we
just
raise
the
levees
up
here
downtown
well,
then
that
you
still
would
have
levies
at
lower
elevations.
So
if
the
river
came
up
it
would
it
would
go
up
in
the
backflow.
A
You
know
basically
up
up
land
from
the
downstream
section.
So
so,
there's
our
levy
phasing
again
a
nearing
completion,
b
and
c
we're
here
to
talk
about
tonight,
we're
in
the
design,
video,
and
so
this
graphic
right
here
maybe
hopefully
gives
you
a
little
bit
more
of
a
picture.
You
know
this
is
the
top
of
the
levee
right
here
with
this
berm.
So
so,
right
now
in
this
graphic,
you
can
see
this
solid
line
right
here.
A
That
is
the
current
top
of
the
levee
okay.
Fema
says
we
need
to
be
three
feet
above
the
hundred
year.
Elevation-
that's
shown
down
here
in
this
kind
of
skip
dash
line
right,
so
our
levee
is
currently
above
above
the
well
above
the
hundred
year
elevation
today,
but
again,
fema
says
it
needs
to
be
three
feet
above
in
most
cases,
and
when
we
approach
bridges
it
needs
to
be
four
feet
above
for
a
certain
distance.
A
So
here's
where
we
need
to
be
this
dashed
line
and,
as
I
mentioned
before,
we're
going
above
and
beyond
that
with
adding
some
buffer
in
there.
So
the
the
gray
shaded
area
is
the
proposed
fill
and
so
so
we're
raising
the
levy
up
in
this
case
almost
about
two
feet.
A
So
if
you
could
visualize
this
being
two
feet
higher,
that's
what
we
need
to
do.
Obviously
this
impacts
the
trail.
We
talked
about
closures.
This
would
be
an
opening
right
in
the
in
the
in
the
system.
You
know,
there's
a
gap
between
this
levy
here
and
this
levy
over
here
for
the
tr
for
the
trail
users
to
get
through,
and
so
that's
a
closure.
So
when
we
do
it
talking
about
closure
improvements,
so
I
don't
know
craig.
B
No,
I
don't
think
the
thing
so
I
can
kind
of
take
over
from
here
and
as
steve
kind
of
stated
stated
here,
this
is
obviously
looking
to
the
west
from
southwest
fifth
street
and
the
the
southwest
fifth
street
bridge,
or
also
known
as
the
jackson
street
jackson
street
bridge,
but
right
here
too,
it's
kind
of
interesting,
because
you
know
we
have
foot
traffic,
that
traverses
kind
of
over
the
top
of
the
levee
and
it's
created
kind
of
a
a
dirt
pathway.
B
Well
that
dirt
dirt
pathway
is
not
a
desirable
thing.
I
mean
that.
Would
that
would
kind
of
show
up
on
levee
inspections
is
something
that
the
city
needs
to
improve
upon,
so
like
at
this
location,
we're
to
steve's
point
we're
going
to
actually
create
an
opening
in
the
levy
and
install
a
a
floodgate
system
or
swing
gate.
So
basically
there'll
be
a
direct.
B
You
know,
path,
connection
from
southwest
5th
street
directly
to
the
the
jackson
street
bridge
also
just
kind
of
a
neat
feature
this,
and
I
you
know
I'll
talk
about
this
just
a
little
bit
more
here
shortly.
Is
you
know
this?
This
section
of
the
meredith
trail
is
on
on
the
riverside.
Well
with
our
levee
improvements.
You
know.
B
But
some
of
the
improvements
with
the
phase
b
project
include,
you
know.
In
phase
b,
project
would
be
from
from
southwest
3rd
street
upstream
to
martin
luther
king,
jr,
parkway
and
includes
you,
know,
earth
and
levy
raises
flood
wall
raises
and
replacement
bank
armoring
with
riprap
and
and
also
gateway
modifications
as
well,
as
you
know,
just
kind
of
abandoning
old
utility
penetrations
that
that
create
a
you
know,
a
pathway
for
for
water
to
get
through,
and
you
know,
potentially
provide
some.
B
B
The
first
phase
is
from
southwest
3rd
street
to
southwest
7th
street,
basically
on
on
both
sides
of
the
river,
and
this
is
going
to
be
kind
of
an
impactful
phase
too,
because
it
involves
closure
of
of
the
meredith
trail
for
approximately
a
three
to
four
month
duration.
But
this
will
be
the
first
phase
of
the
project
and
when
this
work
happens
like
right
away
kind
of
in
the
spring
of
2022
trail,
users
will
have
to
you
know
detour
to
martin
luther
king
jr
parkway.
B
The
nice
part
about
this
phaso
is
it
is.
It
is
shorter
in
duration,
then,
as
we,
you
know
proceed
upstream
with
our
work,
you
know
kind
of
starting
in
the
summer
of
2022.
The
area
shown
there
in
purple
as
well
as
the
orange
section
will,
will
pretty
much
just
exclusively
be
earthen.
Levee
raises
and
stuff
like
that.
But
once
again,
one
of
the
unique
features
of
this
project
is
from
you
know
the
the
the
jackson
street
bridge
or
southwest
5th
street
bridge
to
the
west
to
the
christian
mercy
coleman
bridge.
B
We
will
be
widening
out
the
existing
levee
section
to
accommodate.
You
know
a
future
trail
section
so
that
that's
a
really
kind
of
neat
feature
of
of
this
levee
improvement
project.
B
B
So
the
next
slide
there,
the
phase
c
levy
alteration
project
will
be
more
downstream
of
southwest
3rd
street
to
southeast
14th
street.
This
section
levy
is
kind
of
more
of
a
it's
heavy
on
the
geotechnical
modifications,
because
there's
a
lot
of
rubble
and
debris
that
are
kind
of
within
the
levy
itself.
So
you
know
there's
going
to
be
a
lot
of
geotechnical
work.
Kind
of
done
on
on
this
portion
of
levy,
including
a
seepage
relief
trench,
which
I
think
steve
had
kind
of
mentioned
earlier,
is
something
that
kind
of
captures
water
as
it
flows.
B
You
know
kind
of
underneath
or
through
the
levee
section.
You
know
we'll
also
be
replacing
unsuitable
materials,
as
well
as
doing
earthen
raises,
and
widening
bank
armoring
with
rip
rap
and
gatewall
modifications
and
obviously
old
utility
penetrations.
B
So
the
the
the
picture
shown
here
is
is
basically
at
southeast
sixth
street
looking
west
toward
downtown
and
as
you
look
at
the
the
the
cross
section
view
kind
of
there
at
the
at
the
bottom
of
the
screen,
once
again
kind
of
on
the
east
side
of
the
bridge,
we're
looking
at
nominally,
you
know
a
two-foot
fill
which
is
which
is
somewhat
common
on
on
phase
you
know,
b
and
c,
but
obviously
there
are
sections
that
that
are
less
than
that,
but
there
are
also
sections
that
are
more
than
that.
B
So
on
the
west
side
of
the
bridge,
we're
going
to
be
basically
raising
the
the
levee
4
to
6
feet
now,
a
lot
of
the
reason
behind
that
is
just
because
we're
kind
of
realigning
the
levee
to
create
a
better
trail
connection
or
or
or
street
crossing.
You
know
at
southeast
6th
street
next
slide
there.
Please
steve-
and
this
is
also
just
kind
of
an
overview
map
of
the
entire
faci
project
shown
in
in
blue
there.
B
Also
inlaid
within
the
project
is
a
is
the
iowa
confluence
water
trails
project
there
too,
as
steve's
kind
of
shown
on
the
on
his
screen
there,
and
so
basically
you
know
one
of
the
the
the
neat
features
of
of
this
project,
or
this
phase
phase
c
is
the
jon
pattorian
trail
is
is
really,
as
many
of
you
already
know,
is
in
really
kind
of
rough
shape.
Right
now
it
doesn't
have
it's
not
up
to
current
design
standards
as
well,
either.
B
B
Then,
with
the
with
the
following
slide,
we
get
a
little
bit
more
into
the
the
phasing
of
the
water
trails
project,
as
well
as
the
facey
levy
improvement
project.
B
So
with
this
one
well,
basically
right
off
the
bat
in
in
2022,
we
will
be
starting
to
work
on
the
levees
from
scott
avenue
to
southeast
6th
street
and
that
work.
B
There
is
not
necessarily
going
to
take
us
very
long
to
do,
but
once
we
are
complete
with
that
work
on
the
north
side,
then
central
iowa
or
the
water
trails
improvement
project
will
then
start
their
in
river
and
upland
work
on
the
north
half
of
the
morning
des
moines
river,
as
shown
in
green
there,
and
their
work
you
know
is-
is
anticipated
to
take.
B
You
know
just
short
of
a
year,
so
you
know,
while
we're
going
to
be
within
the
scott
avenue,
to
southeast
six
portion
of
the
levy
for
for
two
to
three
months
time.
Duration,
obviously
they'll
be
there
for
an
extended
period
period
longer
than
that.
As
then,
we
work
downstream
from
from
southeast
6
to
southeast
14th
street.
B
B
The
des
moines
river
from
southeast
sixth
street
to
southeast
14th
street,
but
that's
really
kind
of
a
time
dependent
phase,
and
if,
if
that
does
happen,
where
we
then
kind
of
start
work
on
on
the
south
half
of
the
des
moines
river,
you
know
all
pedestrian
or
trail
traffic
will
then
be
diverted
to
the
new
john
john
pat
dorian
trail
on
the
on
the
north
side
of
the
river.
B
One
other
interesting
feature
that
we're
going
to
be
doing
with
this
phase
too,
is
from
the
pat
cavero
park.
We're
going
to
be
also
grading
for
a
future
trail
connection
underneath
southeast
14th
street
to
the
the
harriet
street
improvements
work.
That
is
also
happening
happening
with
the
water
trails
project
on
the
east
side
of
southeast
14th
street
as
well
so
there'll
be
an
additional
connection
underneath
the
southeast
14th
street
bridge
in
the
future,
a
trail
section
that
will
be
connected
there.
But
we'll
be
grading
that
section
out
now.
B
And
then
moving
along
to
the
next
slide,
if
work
within
that
section
of
southeast
6th
street
to
southeast
14th
street
is
not
completed
in
in
2022,
we
will
basically,
then
just
be
working
on
this
entire
scratch
from
southwest
3rd
to
southeast
14th
street
in
2023,
the
biggest
piece
that
we
have
to
get
done,
and
once
again
probably
one
of
the
more
impactful
pieces
is
from
southwest
third
to
to
scott
avenue.
B
That
portion
of
levy
project
is
also
not
anticipated
to
take
very
long,
approximately
three
months,
but
that'll
be
a
key
piece
to
kind
of
get
done.
So
you
know
we
maintain
kind
of
a
nice
trail
section.
You
know
here
basically
crossing
the
scott
avenue
bridge
and
using
the
new
john
pat
dorian
trail
as
a
detour
route,
but
then
we
will
continue
downstream
of
of
scott
avenue
on
the
levy
project
through
you
know.
Well,
I
guess
kind
of
we
anticipate
completion
in
in
fall.
B
I
guess
of
2023,
whether
it's
to
to
south
southeast
6th
street
or
southeast
14th
street,
the
whole
section
should
be
completed,
then
by
fall
of
2023
with
a
with
a
whole
new
trail
section.
B
While
that
work
is
going
on
and
once
the
the
levy
project
work
is
kind
of
completed
at
scott
avenue
or
or
southwest
first
street,
that's
when
the
water
trails
project
will
also
be
in
there
for
an
additional
18
months,
so
through
kind
of
october
of
2024
doing
their
in
river
and
upland
improvements
that
that
steve
had
briefly
touched
on
earlier
in
the
presentation.
B
With
the
next
slide,
too,
we'll
we'll
you
know
the
on
the
city's
website
under
the
engineering
department
under
projects
and
studies,
we
also
have
a
web
link
for
the
des
moines
levy
alterations
program
and
within
that
link
we'll
be
providing
construction
updates,
trail
closures
and
stuff,
like
that.
So
it's
just
another
kind
of
neat
little
thing
to
get
information
out
there
with
all
that
being
said,
I
guess
any
questions.
A
A
We're
talking
about
earth
and
embankment
levy
raises
again
elevating
the
lev
stripping
off
the
top
kind
of
the
top
soil
layer
and
then
lit
elevating
the
levee
with
compacted
lifts
of
clay
materials
to
raise
it
up
to
the
proper
elevations
so
stripping
it
down.
Then
building
it
back
up
to
the
the
new
more
higher
elevation.
So
so,
as
craig
mentioned,
do
we
have
any
yeah?
A
That
was
a
lot
of
information
to
put
at
you
is:
do
we
have
any
any
questions
or
comments
from
from
our
folks
on
the
on
the
meeting.
A
And
if
you,
if
you
think
of
any
late
or
two,
please
don't
hesitate.
I
have
craig's
information
up
here.
Contact
us.
C
A
Yep,
that's
a
good
question.
Jim
is
correct
because
we
are
raising
levy.
You
know
three
to
four
feet
when
you,
when
you
carry
the
slopes
out,
that
would
that
will
also
widen
the
footprint
of
the
levee
and
then
obviously
on
on
phase
b,
craig
mentioned
and
actually
the
john
pat
dorian
trail
on
the
north
side
of
the
river
that
you
know
we're.
A
Actually
you
know
the
trail
for
the
jon
pat
dorian,
I
think,
is
only
like
seven
feet
wide,
so
there
we
would
also
be
winding
to
accommodate
a
wider
trail
and
then
provide
the
two
foot
shoulders
as
well,
but
yeah
so
in
general,
because
of
the
levee
raises
it
it
the
footprint
winds
as
well.
So
I
think
there
is.
A
You
know
there
is
some
property
impact,
so
some
people
who
are
right
along
the
levee
system
would
have
to
be
may
have
already
been
contacted
by
our
real
estate,
folks
about
getting
easements
or
or
those
impacts.
Exactly
anything
craig.
I
miss
anything
there.
B
No,
I
said
I
was
gonna
say
that
steve.
I
think
you
pretty
well
covered
it.
I
we
had
a
fair
amount
of
of
all
the
real
estate
we
need,
so
that
really
the
need
on
both
projects
was
was
was
somewhat
minimal.
D
C
A
B
Yeah
that
that
that
section
of
levy
is
kind
of
unique
because
that's
like
I
said
earlier-
is
kind
of
where
a
lot
of
our
geotechnical
modifications
are
coming
or
are
going
to
be
done
in
that
area.
So
really,
within
that
section
we're
basically
doing
a
pretty
much
an
equivalent
amount
of
landside
and
riverside
widening
and
basically
what
we're
doing.
In
some
cases,
you
know
where
we
have
some
issues
with
with
seepage
or
whatever
we're
creating
a
cap
or
a
impermeable
layer
of
dirt
kind
of
more
on
the
river
side
of
things.
A
Is
this
showing
the
kind
of
the
limits
craig
right
here
and
see
how
this
kind
of
flares
out
right
there
yeah
that's
correct?
Okay,
so
so
it
looks
like,
like
you
said,
between
scott
and
south
e6,
it's
kind
of
split,
so
the
widening
would
kind
of
occur
on
both
sides,
except
for
right
down.
Here
looks
like
there
is
some
more
riverside
on
this
side,
so
it
looks
like
it
is
a
lot
split
through
these
phases.
A
B
But
but
a
lot
of
times
to
also
add
on
to
that
too,
we
it
is,
you
know,
because
of
the
full
frequency
study
you
know,
has
increased
our
flows
and
what
not
to
you
know
most
of
the
time,
with
the
exception
of
kind
of
this
area
too,
we
are
generally
widening
more
to
the
land
side,
because
we
cannot,
you
know,
inhibit.
You
know
flow
more
riverside
because
of
that
increased
flow
frequency
that
we
have.
A
I
think,
if
I
recall
usually
we're
sitting
at
about
a
three
to
one
slope
right
and,
and
so
correct
me
if
I'm
wrong,
so
in
other
words,
if
we're
raising
the
levee
say
two
feet
that
toe
of
the
levee,
the
bottom
of
the
levee
here
see
this
little.
The
toe
here
would
be
going
out
another
six
feet
than
it
is
today
so
correct.
A
Just
while
people
are
are
thinking
that
you
know
just
one
thing,
I
think
in
generality
craig
correct
me
if
I'm
wrong
but
2022
down
here
in
this
area,
phase
c
in
the
water
trails
project
2022
anticipate
a
lot
of
work
between
scott
avenue
and
southeast
14th
street
for
the
pretty
much
the
whole
year
2022.
I
know
craig's
got
it
broken
down
into
phases
here,
but
2022
the
north
side
of
the
river
2023,
the
south
side
of
the
river,
and
then
the
water
trails
actually
is
2023
and
2024
for
the
end
river.
A
A
D
I'm
not
sure
how
to
raise
my
hands.
That's
right,
john!
Go
ahead!
Yes,
on
the
on
this
slide
here,
where
there's
the
number
four
and
then,
if
you
go
up
or
if
you
go
to
the
right
a
little
bit
and
go
yeah
right
around
there,
there's
that
part
towards
the
bottom
looks
like
it's
separate
kind
of
right.
There,
yeah
you're
on
the
right
hand,
side
of
it
like
if
you
just
yeah
right
well
to
the
left,
a
little
bit
like
right,
where
the
arrow
is
pointing
like
right
at
the
tip
of
that
arrow.
D
A
Craig
is
that
a
is
that
delineating
a
seepage
control
structure,
or
is
that
see
how
it's
kind
of,
as
john
mentioned
it's
it's
kind
of
its
own
line
there?
Is
that
delineating
a
seepage
trench?
Do
you
know
there
right
well.
B
That's
the
levee
I
mean
predominantly
the
meredith
trail
is-
is
riverside.
I
think
there,
oh
yeah
so
yeah
that
that's
what
that's
kind
of
depicting-
and
I
think
you
know
some
of
the
stuff
that's
going
out
to
the
bow
straight
wall.
There
too,
is
you
know
we're
armoring
that
that
section
with
riprap,
so
that's
kind
of
why
it's
showing
that
that
really
wide
kind
of
area
of
improvement
there.
B
A
So
this
this
line
right
here
is
the
levy
yeah
and
then
it
is
being
raised,
but
it
looks
like
most
of
the
fill
will
be
down
to
the
ballast
trade,
which
is
this
so
then
the
trail
is
the
trail
is
not
on
the
levy.
It's
it's
right
next
to
the
levee
or
on
the
riverside
right
next
to
the
levee.
So
with
that,
okay,
thank
you.
Where
was
that
picture
just
here?
Let
me
find
so
well,
that's
not
it!
A
The
levy
would
be
like
if
there
was
a
berm
right
over
here
sure,
and
so
then,
if
we
raise
that,
then
the
trail
would
have
to
be
raised.
I
assume
craig
right
and
then
tapering
down
yep
yeah.
I
thought
we
had
a
oh.
D
A
D
C
Okay,
so
that
last,
when
you
had
that
last
elevation
slide
up
according
to
like
the
river
gauge
the
south
side
at
east.
Sixth-
it's
it
says
the
levee
height
is
like
37
36.9
or
something
at
the
east
sixth
street
river
gauge.
C
A
Right
here
we're
showing
the
des
moines
from
the
at
the
des.
Moines
datum
it's
it's.
You
know
this
is
showing
the
existing
levy
at
about
24..
A
C
A
C
C
A
Yeah,
okay,
so
there
there
be
a
conversion
to
the
between
the
two
correct
yeah
and
I
and
I
don't
yeah
I
pledge
we
don't-
have
have
that
yeah.
A
Yeah
yeah
you
you're
you're
asking
is
there?
How
are
these
numbers
in
relation
to
the
river
gauge?
Were
they
the
same
or
they're?
Not
and
so
they're,
not
they're,
not
the
same
as
the
river
gauge
elevations
that
you
see
right
that
are
stages
of
the
river.
This
is
actually
just
a
city.
The
city
created
a
survey
datum
and
right
so
we're
not
using
the
the
national
I
mean
we
can
convert
it,
but
there's
a
a
you
know
above
sea
level
datum.
This
is.
D
C
A
Yep
yep
we
did
have
to
go
through
and
and
jim
brings
up
a
good
point
on.
He
talked
about
at
certain
elevations
of
the
river.
We
have
a
flood,
a
flood
mitigation
plan
where
we
so
so.
Obviously
you
know
when
there's
there's
say
storm
sewers
that
go
underneath
the
levee
to
discharge.
You
know
the
flow,
that's
that's
the
rain
water!
That's
coming
internal
behind
the
levee.
A
When
the
river
gets
so
high.
We
have
to
close
those
those
gate.
We
have
gates
that
we
close
to
seal
up
the
sewers,
so
the
water
doesn't
come
up
the
flood
waters
and
come
up
through
the
sewer
and
into
the
system
internally,
and
then
we
have
we
built
brand
new
pump
stations
and
one
of
them
right.
You
know
between
scott
avenue
and
southeast
six
right
dead
center
between
the
two,
a
big
new
pump
station
and
we
elevated
pipes.
A
So
so
there's
pipes
that
go
over
the
flood
protection
system
and
that
pump
station
pumps,
the
rain
water
behind
the
levee
system
over
into
the
river,
and
so
that's
what
jim's
talking
about.
When
we
talk
about
stages,
we've
got
to
cl
at
certain
river
elevations.
We've
got
to
close
those
gates,
so
the
water
doesn't
come
up
through
the
storm
sewers
that
go
underneath
the
levee
or
through
the
levee
essentially,
and
then,
even
beyond
that,
we
talked
about
the
closures.
A
If
it's
a
high
enough
stage,
we
would
have
to
start
implementing
the
closures
so
like
the
gates
at
the
at
the
you
know,
like
the
the
simon
says,
amphitheater,
for
example,
we
would
we
would
close
those
gates
at
certain
river
elevation
stages
before
the
river
gets
all
the
way
up.
So
that's
what
jim
is
talking
about
there
when
our
flood
fighting
plan.
A
D
B
That's
only
at
that
at
that
one
particular
location,
and
I
get
why
that's
kind
of
like
showing
that
extreme
amount
of
fill
is
because
we
are
realigning
the
levee
to
be
a
little
bit
more
landside.
So
they're,
you
know
we're
actually
shifting
it
over.
It
would
be
on
the
opposite
side,
obviously
of
southeast
six,
because
on
the
side,
steve,
where
you
got
your
hand
right
now,
you
know
that
that's
actually
the
section
that's
getting
two
feet
of
fill,
but
on
the
west
side
it's
it's!
B
You
know
it's
a
little
bit
heavier
because
we
are
doing
a
little
bit
of
a
realignment
effort
there.
I
think
I
might
have
seen
this
earlier,
but
normally
within
these
you
know,
phase
b
and
c
projects.
You
know
the
the
generally
the
most
fill
that
we're
we're
going
to
see
is
around
that
2
foot
mark
and
and
we
could
see
as
little
fill
as
a
half
a
foot.
B
A
D
B
A
Again,
if
you
think
of
any
later
I'll
again,
obviously
please
check
out
our
city
website.
Also,
you
know
I've
got
craig's
information
up
here.
The
283
4580
number,
if
you
think
of
any
later.
C
A
Yep
yep
we'll
actually
post
it
on
this
project
and
studies,
location,
a
link
to
it,
we'll
download
it
it'll,
take
us
a
day
or
two
just
because
the
size
of
the
video
but
yeah
jim
is
that
something
you'd
like
us
to
email
to
you
that
link.
Would
that
help.
A
Hurt,
okay
but
yeah
it'll
be
right.
If
you
go
to
our
pro
engineering
projects
and
studies
page,
you
see,
there's
a
whole
bunch
of
different
projects.
Here
the
des
moines
levee
alterations.
We
will
post
the
video
you
know
and
there's
other
information
on
that
website
as
well.
You
know
kind
of
schedule
and
stuff
like
that,
so
they
don't
have
to
watch
the
video
for
the
some
information
but
but
yeah
we'll
post
it
right.
There.
A
So
again
you
go
to
the
city
website,
dsm,
dot
city

then
you
can
go
to
the
engineering
page
projects

studies
and
that'll.
Take

lot
of
infrastructure
improvements
to
say
the
least
bridges
storm
water,
especially,
and
so
we
know
construction
is
very
impactful.
It's
I
live
on
the
east
side
in
des
moines
and
I
am
I'm
taking
detour
routes
now
as
we

to,
but
we're
we're
we're
very
excited
about

improvements
we're
making
improving
our

A
Our

mitigation,
very
importantly
here,
including
this
one,
providing
more
more
reduce
reducing
