San Bruno City Council Meeting June 10, 2014
10d. Storm Drain Master Plan
A
B
Honorable
mayor
councilmembers,
the
city
provides
many
services
to
our
asset
to
our
residents
in
order
to
maintain
a
certain
level
of
quality
of
life
and
to
protect
public
health
and
property.
Many
of
those
services
like
water,
sewer,
roads,
transportation,
stone
required
and
need
a
infrastructure
to
provide
those
services.
B
As
responsible
managers
for
those
system
for
the
city,
you
are
Eddie,
approved
the
updated
master
plan
for
our
water
system
for
our
sewer
system
and
also
you
are
approving
an
ongoing
basis.
Our
payment
management
system
at
our
storm
master
plan
is
the
last,
certainly
not
the
least
important
system
which
need
this
long-term
assessment
being
wrong.
Is
the
project
manager
for
this
project
and
he
will
take
you
through
the
content
of
the
master
plan?
C
Good
evening,
mayors
and
council
on
the
somme,
dream
master
plans
provide
the
thorough
evaluation
of
the
storm
system.
It
defines
a
long-term
capital
improvement
program
and
it
also
serve
as
the
roadmap
for
future
rate
studies
and
storm.
The
revisions
for
the
implementation
of
the
proposed
improvement.
C
To
give
you
a
little
background
and
history,
the
City
Council
adopted
a
storm
system
study
in
1991
and
then
an
update
after
study
in
two
thousand
and
this
2014
Sundering
master
plan
that
we
are
presenting
is
the
city's
first
comprehensive
storm
system
master
plan
and
they
are
some
significant
accomplishment.
With
this
master
plan,
the
city
had
the
least
information
on
the
storm
system
compared
to
sewer
and
water
and
at
the
early
stage
of
the
master
plan
preparation.
C
This
map
here
shows
basically
the
islets
ten
Bruno
stomps
drain
system.
There
are
six
watersheds
and
they're
labeled,
a
b
c
d,
e
and
f
and
in
general,
the
storm
water
runs
from
the
west
to
the
east,
the
major
branches
of
the
sewer
system.
They
were
constructed
in
the
early
1900s
and
at
the
bel-air
culvert.
Here,
that's
the
backbone
of
the
of
the
storm
system,
and
the
collection
system
consists
of
inlets
V
ditches,
pipes,
culverts
earth
channels,
concrete
channels.
C
C
C
However,
any
storm
that
was
about
that
in
a
ten-year
25-year,
that
would
be
a
lot
of
flooding.
But
if
we
were
to
select
like
100
year,
storm,
maybe
even
go
up
to
150
years.
No,
it
would
be
very
expensive.
It
would
probably
end
up
being
rebuilding
half
this
city
storm
system,
and
that
becomes
unrealistic,
and
so
at
the
early
stage
of
the
preparation,
the
25
years,
storm
was
selected
and
what
are
the
results
of
other
that
this
hydraulic
model
it?
They?
C
It
predicted
that
a
localized
flooding
conditions
throughout
the
city
in
a
25-year
storm,
and
this
next
few
slides
would
prepare
in
response
to
requests
from
the
utility
subcommittee
and
what
what
are
the
problem
areas
and
again,
the
problem
areas
defined
as
area
that
will
likely
flood
in
the
25-year
intensity
storm.
So
this
is
watershed
a
and
you
can
see
the
circled
areas
of
the
problem
areas.
You
got
some
a
long,
El
Camino
and
then
there
are
some
moving
towards
huntington
in
this.
C
C
Anyone
storm
water
that
goes
into
the
system
will
be
able
to
be
conveyed
and
go
into
the
channel
where
the
detention
option
is
they
the
ones
that
allow
for
some
room
in
the
system
to
hold
er
hold
on
to
the
rain
water
a
longer
period
of
time,
so
it
doesn't
overflow
and
the
main
difference
between
the
pipe
option
and
the
detention
option.
Is
that
there's
a
major
pipe
improvement
project
in
watershed,
a
between
in
the
state
I
280
and
el
camino?
Real?
C
And
what
are
the
recommended
improvement?
There
are
five
priority
project
the
priority
one
project,
and
probably
one
projects,
are
the
ones
that
basically
will
cost
a
major
flooding
event
if
that
would
cause
the
major
flooding
events
and
so
the
the
five
priority
one
project
consists
of
the
customer
canyon,
detention
bases
and
for
other
pipeline
improvement
projects
for
total
of
twelve
million
dollars.
That's
also
when
million
dollars,
four
minutes,
the
total
regional
permit
compliance
and
for
the
long
term,
trash
control,
operation
and
maintenance.
C
In
addition,
there
are
seven
proudly
two
projects
for
seven
million
dollars:
the
total
of
the
20
million
dollars.
The
basket
plan
also
identified
two
county
flood
control
project,
and
then
they
are
the
rehabilitation
of
these
of
the
tiger
and
also
the
walnut
and
the
Angus
pump
station,
and
this
slide
shows
the
location
of
the
tie,
gate
and
then,
and
also
the
water
pump
station.
C
C
So,
in
conclusion,
it's
been
a
long
time
coming
and
we
finally
have
a
comprehensive
storm
system
master
plan
in
place.
It's
it
provides
a
definitive
camera,
kept
capital
improvement
program.
It
also
identified
funding
issues
or
the
lack
of
funding
issues
and,
as
the
first
step
towards
the
you
know,
improvements
for
the
some
system
in
the
level
of
services
staff
is
recommending.
The
adoption
of
this
2014
storm
drain
master
plan
by
the
City
Council,
and
that
concludes
my
presentation
and
I'm
here.
To
answer
questions
I.
D
Mr.
eagle,
you
had
a
question
Robert
recall
seventh
Avenue
down,
though
excuse
me
very
near
Angus,
where
you
said
there
are
concerns
and
the
the
pipe
that
is
kind
of
gets
the
brunt
of
the
water.
You
talk
about
in
your
proposal
that
a
25-year
storm
back
in
2000
2003,
the
two
or
three
big
storms
that
came
through
people
had
said
that
possibly
they
were
upwards
of
the
rated
at
a
hundred
year
storm.
D
D
C
C
C
B
I
might
add
some
additional
information.
Is
that
also
all
of
the
improvements
under
the
rail
which
were
part
of
the
great
separation
project
they
were
designed
and
implemented
for
100
your
storm?
Isn't
their
capacity
under
the
track
is
able
to
basically
take
the
100-year
flood
event,
also
in
case,
if
the
main
culvert
will
be
designed
that
will
be
contemplated
during
the
design,
but
will
be
the
appropriate
level
of
design
in
more
details
specifically
for
that
pipe,
but
would
be
the
cost
differential
and
what
would
be
the
best
solution
at
that
time?
B
How
to
design
that
culvert
to
that
size,
and
also
the
series
started
having
discussion
with
the
Flood
Control
District,
which
really
is
the
most
critical
partner
in
this
addressing
the
overall
risk
involved
in
any
kind
of
major
flood
event
and
was
our
discussion
that
will
be
developed
a
plan
in
case
or
in
those
cases.
What
would
be
the
plan,
including
and
I?
Don't?
This
is
just
a
preliminary
phase,
even
developing
some
kind
of
agreement
with
the
airport,
how
you
could
release
those
excess
water
and
what
would
be
the
solution
in
those
situation.
E
Alright,
we're
on
the
subject
of
the
canyon
still
so
I'm
assuming
that
detention,
when
you
say
detention
will
mean
that
you're
going
to
collect
water
in
the
canyon,
mostly
from
the
western
part
of
the
city,
you
know
so
that
allows
allows
the
flow.
You
know
a
lot
easier
to
towards
the
east
I'm,
assuming
that
all
the
discussions
about
what
we
heard
earlier
on
land
slight
improvements
and
any
other
improvements
that
are
going
to
be
discussed
now
in
a
preliminary
stage.
E
B
Certainly,
this
is
a
known
recommendation
and
will
be
part
of
you
are
ad
approved
a
preliminary
assessment
of
the
geological
condition
of
the
whole
Canyon
and
during
those
assessment,
part
of
the
physical
of
how
to
integrate
in
the
overall
design
of
the
canyon
and
improvement
in
the
canyon.
How
stabilized
how
to
implement
any
improvement.
This
project
will
be
a
important
component
and
maybe
also
will
provide
some
enhancement
to
that
whole
redesign
environment
of
the
canyon.
But
certainly
this
is
a
known
project
and
will
be
part
of
the
consideration
that.
B
The
storm
drains,
you
say,
parcel
tax,
the
city
is
in
a
even
better,
you
say
not
entirely
unique,
but
not
too
many
cities
in
san
mateo
county
has
this
special
revenue.
You
say
parcel
tax
and
everybody
pays
around
50-54.
I
don't
remember
exactly,
but
I
don't
around
that
dollar
amount
and
the
total
revenue
is
between
500
and
600
thousand
a
year.
This
year
was,
I
think,
is
budgeted.
509
a
dollar,
but
typically
those
are
almost
all
of
their
dollar.
B
A
B
A
So
it's
a
protest
vote.
Correct,
okay
to
chair,
I,
recall
a
discussion
when
we
were
talking
about
the
Seward
water
rates
that
anything
that
was
placed
on
a
tax
roll
was
subject
to
a
vote.
A
general
population
vote
not
a
218
process
which
is
limited
to
fees
and
things
that
are
you
basically
get
something
for
what
you
pay
well,
we'll
need
to
look
into
that
and
we'll
come
back
to
you
with
an
answer.
A
We're
not
really
prepared
to
to
address
it
this
evening,
but
we
understand
the
question
and
we'll
make
sure
that
everybody
gets
an
answer
shortly.
Okay,
thank
you
anything
else.
Michael
I
would
just
comment
that
the
action
before
us
today
is
simply
approving
the
plan,
but
I
I
do
think
it
would
be
prudent
to
start
looking
at
funding
sooner
rather
than
later,
rather
than
putting
it
off
for
two
years.
A
I
think
now
that
we
have
an
idea
of
what
we
need
to
undertake
and
the
magnitude
of
the
cost
that
certainly
now
that
the
economy
is
doing
well
and
we
have
some
options
that
would
be
good
to
start.
Considering
these
things,
as
well
as
all
the
other
projects,
you
mentioned,
that
that
need
to
find
funding
sources
sooner
rather
than
later.
Just
that
comment
agreed
any
action
by
the
council
I'll.
