From YouTube: This Week in Ames
Description
Water and Pollution control director John Dunn stops by to update us on the Flood Mitigation Study.
A
A
You've
had
a
very
busy
week
and
it
kind
of
culminated
with
the
presentation
to
the
aim:
City
Council
recently
about
final
strategies
for
flood
mitigation.
The
process
itself
was
very
took
very
many
months
and
involved
a
lot
of
information.
Can
you
just
walk
us
through
how
we
got
to
that
recent
presentation?
Well,.
B
B
So
they
were
looking
at
developing
a
hydrologic
model,
sort
of
a
rainfall
model
and
then
also
a
hydraulic
model,
which
is
what
happens
once
the
water
hits
the
ground
and
using
that
they
performed
a
new
statistical
calculation
to
define
what
constitutes
the
other
definition
of
a
hundred
year,
flood,
which
is
an
important
definition
in
managing
the
floodplains
and
then
they
they
also.
Then,
the
next
phase
that
they
moved
into
was
looking
at
the
development
of
mitigation
alternatives.
So.
A
A
B
In
the
simplest
form,
what
they
meant
by
mitigation
was
just
looking
at
trying
to
reduce
the
impact
of
flooding,
and
you
can
do
that
in
a
couple
different
ways.
You
can
do
it
by
trying
to
move
properties
out
of
the
floodplain.
You
can
do
it
by
trying
to
protect
properties.
You
could
do
it
by
trying
to
move
water
out
of
aims
faster
or
you
could
do
it
by
trying
to
hold
water
up
in
the
watershed
longer
and
the
alternatives
that
HD
are
developed
and
looked
at,
ran
the
gamut
of
that
full
spectrum
of
possibilities.
B
A
B
The
the
modeling-
well,
it's
a
fairly
straightforward
exercise.
It
is
pretty
time-intensive
there.
As
you
mentioned,
there
was
a
substantial
public
involvement
component
to
what
happened.
We
held
a
series
of
public
workshops
that
actually
started
in
October
of
2012
and
continued
through
to
the
spring
of
2013,
as
the
design
team
or
the
engineering
team
was
developing
their
alternatives.
They
they
were
repeatedly
coming
and
presenting
those
to
the
public
in
either
open
house
formats.
You
a
very
informal
setting-
or
we
also
did
the
real,
formal
podium
presentations
with
question-and-answer
sessions.
B
In
addition
to
all
those
in
public
meetings,
there
was
also
an
online
meeting
that
ran
the
entire
time
that
the
study
was
underway
so
through
through
those
different
mechanisms.
We
we
receive
literally
hundreds
of
comments
from
the
public,
and
many
of
those
ideas
were
incorporated
into.
The
final
evaluation
were.
B
B
In
april
of
2013,
we
held
a
workshop
with
the
council,
where
we
presented
them
a
number
of
individual
discrete
mitigation
measures
that
could
be
undertaken.
What
we
were
presenting
to
the
council
this
week
was
taking
those
and
starting
to
pair
them
up
in
combinations
that
look
like
they
made
sense,
both
in
terms
of
having
some
synergistic
impacts
in
terms
of
reducing
the
impact
of
the
flooding
and
also
some
cost
efficiencies.
And
so
we
presented
to
the
aim
City
Council
this
week
for
combination
alternatives
for
them
to
consider
and.
A
B
Certainly,
and
in
many
of
the
public
comments
that
we
got
could
could
fall
into
one
of
three
categories:
some,
and
it
really
depends
on
where
you
live.
What
you
would
like
to
see
done
with
with
flooding
there
was
was
a
one
group,
a
catacomb
ants
that
were
people
who
live
south
of
Ames,
who
were
saying:
please
don't
do
anything
to
speed
up
the
flow
of
water.
B
A
B
The
City
Council
will
they'll
have
to
weigh
the
alternatives
and
decide
which,
if
any
of
those
that
they
want
to
move
forward
on
the
the
timeline.
If,
if
a
project
was
going
to
appear
in
the
next
update
to
the
city's
capital
improvement
plan,
we
would
probably
need
to
have
some
direction
by
the
end
of
november,
so
that
it
can
be
incorporated
when
that
plan
gets
published
in
early
january.
You.
A
B
There
was
one
alternative
that,
from
the
staff
perspective
seemed
like
it
was
the
one
that
made
the
most
sense
and
it
was
in
the
in
the
written
report.
It
was
referred
to
as
combination
alternative
number
one
and
it
involved
pairing
up
to
individual
strategies,
one
of
which
was
to
extend
the
span
of
the
US
highway
30
bridge
by
about
400
feet.
B
Basically,
opening
up
the
the
space
under
that
bridge
to
allow
water
to
pass
through
and
in
conjunction
with
that,
then
doing
some
reshaping
of
the
creek
channel
in
the
immediate
vicinity
of
South,
tough,
going
about
a
thousand
feet,
or
so
upstream
and
downstream
of
the
Duff
crossing
and
reshaping
that
channel
into
a
more
of
a
trapezoidal
shape.
It's
a
more
hydraulically
efficient.
It
would
allow
water
to
move
through
there
quicker
now.
A
B
A
In
general,
when
you
hear
from
the
public,
obviously
everybody
has
their
own
sort
of
concerns,
but
is
there
concern
about
doing
something
versus
doing
nothing,
or
is
it
that
we're
not
headed
in
the
right
direction?
What
are
some
of
the
criteria
you,
you
kind
of
fit
think
about
when
you're
looking
to
perceive
oh.
B
There's
a
lot
of
different
perspectives
that
folks
are
looking.
Certainly
if
they
own
or
live
in
property,
that's
impacted
by
flooding.
They
desperately
want
to
see
some
sort
of
protection
from
that
there's
also
a
different
school
of
thought,
which
is
that
the
individual
property
owners
should
buy
flood
insurance
and
protect
themselves
and
that
and
that
perhaps
it's
not
an
obligation
of
the
of
the
government
to
protect
them
from
that
there
are
folks
who
have
interest
in
issues
like
water
quality.
B
You
know
doing
some
land
management
practices
further
in
the
watershed
that
would
have
benefits
both
in
terms
of
flood
protection
and
aniston
general
water
quality.
There's
folks
who
have
concerns
about
environmental
impacts
of
any
of
the
mitigation
strategies.
That's
certainly
an
important
consideration
as
well.
So
there's
it
is
such
a
complex
issue
and
there
are
so
many
different
perspectives
that
need
to
be
considered
that
that's
what
makes
this
such
a
challenging
process.
Some
some
folks
are
frustrated
that
you
know.
B
B
You
know
if
somebody
were
to
tell
me
you
know:
when
is
it
going
to
rain?
What's
the
pattern
of
the
rainfall
we're
in
the
watershed?
Is
it
going
to
fall
how
much
rain
if
we
had
in
the
two
weeks
prior
to
that?
How
high
are
the
rivers
at
the
time
the
rain
falls
if
I
know,
all
of
that,
I
can
probably
give
you
a
pretty
good
estimate
as
to
how
high
it's
going
to
get
but
you're
right.
B
Every
rainfall
event
is
different,
just
in
terms
of
even
if
you
get
the
same
amount
of
rain
where
it
falls
in
the
watershed.
The
timing
of
the
peak
between
the
creek
and
the
skunk
river
has
a
significant
impact
on
what
the
flood
heights
are,
that
we
see
in
the
South
stuff.
So
it's
a
pretty
complex
issue
to
be
able
to
give
a
single,
discrete
answer
to
I.
Think.
A
B
That
would
that's
that's
a
really
neat
tool
that
came
out
of
this
study.
Hdr
was
partnered
with
the
Iowa
flood
Center
through
the
University
of
Iowa
to
do
the
modeling
in
the
mapping
and
if,
if
people
were
to
go
to
the
Iowa
flood
Center
website,
which
is
Iowa
flood
Center,
o
RG
and
go
to
the
flood
information
system
following
the
links
through
there,
you
can
get
to
the
community
flood
mapping.
B
And
you
can
you
can
pull
up
a
high
resolution
map
where
you
can
zoom
in
on
your
specific
property
and
then
by
adjusting
a
slider
bar
tell
it
do
you
want
to
look
at
what
the
flooding
would
be
like
on
a
10
year,
flood
of
50
year
flood
a
500
year
flood
and
it
will.
It
will
give
you
a
map.
Now,
there's
a
there
might
be
a
desire
to
be
able
to
trust
those
maps.
Implicitly
and
I
would
hope
people
remember
when
they
go
there.
B
That's
a
theoretical
projection
and
I
always
tell
people,
don't
let
what
you
hear
on
the
news
or
from
somebody
like
me,
interfere
with
your
own
best
judgment.
People
are
the
best
judges
of
the
history
of
their
property
and
they
should
protect
themselves,
but
in
terms
of
planning
ahead
and
protecting
that
inundation
mapping
tool
is
a
really
really
handy
thing.
It.
A
A
B
B
You
know,
I
would
expect
that
we
would
probably
spend
the
first
year
trying
to
line
up
funding
for
whatever
project
we
were
going
to
do
and
then
once
we
have
that
that
funding
mechanism
lined
up
then
there'd
be
a
period
of
time
for
design
and
then
some
some
not-insignificant
environmental
reviews
and
permitting
that
would
need
to
happen.
So
it
would
probably
be
about
three
years
out
before
any
construction
actually
where
to
begin
well.
A
B
That
process
is
is
well
underway
and
design.
We're
probably
I
would
say
roughly
at
about
seventy
percent
complete
on
the
design.
We
are
on
schedule
to
have
the
design
completed
in
March
of
2014,
we're
assuming
about
a
three
month
window
for
permitting
of
that,
and
so
a
notice
to
bidders
will
likely
happen
in
July
of
2014
and
hopefully
a
year
from
now
there
will
be
a
hole
in
the
ground
in
that
property
out
on
East
13th
street.
So.
B
A
B
A
I
have
some
things
to
mark
on
your
calendar
for
November.
Remember
as
Thanksgiving
approaches,
the
city
hall
in
motor
city
offices
will
be
closed
on
November,
28
and
29.
Also,
don't
forget
if
you
still
have
leaves
we
have
two
yard
waste
free
days
coming
up
the
last
two
or
November
16th
and
November
30th,
those
are
from
8am
to
4pm
and
you
can
get
more
information
on
our
website.
Well,
that's
our
show
for
today,
thanks
for
watching
and
tune
in
next
week.
For
this
weekend,
Ames.
