San Bruno City Council Meeting February 24, 2015
10c. Authorize Agreement for LED Streetlight Conversion
A
B
Evening,
mr.
mayor
members
of
the
council,
we
have
come
before
you
in
the
past
with
an
update
on
replacing
our
existing
street
light
fixtures.
As
you
know,
we
have
approximately
2,100
street
lights
throughout
the
city.
Ninety-Five
percent
of
them
are
the
Cobra
head.
As
you
see
on
the
majority
of
the
streets
in
the
area
we
about
five
percent
of
them
are
ornamental,
which
you
see
based
basically
in
downtown
and
some
in
the
Bay
Hill
area.
B
B
We
wanted
to
get
better
electricity
usage
out
of
this
lower
electric
bill
substantially
if
possible,
and
we
wanted
to
have
better
reliability
and
less
failure
of
these
pictures.
So
what
we
did
was
we
looked
at
the
LED
technology
over
a
long
period
of
time
and
we
watched
it
get
better
and
better
more
manufacturers
coming
into
the
into
this
type
of
business,
creating
fixtures
that
would
apply
to
the
streetlights.
We
contacted
many
other
cities
throughout
the
Bay
Area
and
throughout
California,
and
we
try
to
learn
from
their
experiences
and
from
their
mistakes.
B
We
looked
at
the
rebates
available
that
will
reduce
down
the
cost.
For
us,
we
looked
at
financing
options
as
where
do
we
actually
get
the
funds
to
start
the
project
pay
back
through
the
say
beings,
and
we
also
looked
at
certain
part
of
our
system,
which
is
regulated
output
or
the
series
fixtures
there,
approximately
350
out
of
the
2100
that
are
on
those
series
circuits
and
we
want
to
see
what
we
can
do
with
those.
So
over
this
period
of
time,
the
technology
has
improved
tremendously.
B
The
prices
have
come
down
tremendously,
but
also
the
rebates
have
come
down,
not
20,
but
have
to
come
down
quite
a
bit
since
we
were
looking
at
in
the
first
place.
So
we
at
this
point
in
time,
based
on
all
the
experiences
other
cities
based
on
the
information
we
got
from
all
the
different
manufacturers
and
contractors.
The
prices
have
come
down
to
a
point
that
we
want
to
make
a
recommendation
to
you
with
a
system
that
would
work
for
our
city.
This
will
save
electricity
in
the
magnitude
or
approximately
one
hundred
thousand
dollars
a
year.
B
B
It
has
reduced
crime
in
other
cities,
and
we
also
coordinate
it
with
our
finance
department
as
to
how
we're
actually
going
to
finance
this
and
be
able
to
pay
back
less
than
ten
years,
hopefully
nine
years,
eight,
perhaps
or
even
seven,
depending
on
how
the
maintenance
saving
is
going
to
come
into
effect.
So
with
that
I'm
going
to
turn
it
over
to
William
Lee
our
management
analyst.
To
give
you
the
details
of
our
current
recommendation.
C
Thank
you
Ray
good
evening,
honorable
mayor
members
of
the
City
Council,
the
street
light
replacement
project
is
included
in
the
adopted
1419
CIP
budget,
with
the
three
main
project
goals
that
mr.
razavi
just
mentioned,
which
are
illumination
and
safety,
reliability
and
energy
savings.
The
current
lights
that
the
city
utilizes
our
high
pressure,
sodium
and
metal,
halide
lights,
and
these
lights
are
outdated
and
do
not
mean
any
of
the
three
goals.
C
As
you
can
see,
from
the
chart,
LED
lights
surpass
high-pressure
sodium
meta
metal
halide
in
all
categories.
The
LEDs
can
reach
a
higher
temperature,
and
this
is
achieved
with
the
lower
power
usage
compared
to
the
high-pressure
sodium.
By
about
sixty
to
seventy
percent,
the
high-pressure
sodium
lights
use
a
lot
of
power,
but
cannot
reach
a
high
temperature,
which
is
why
these
lights
omit
that
orange
glow
that
we're
used
to
the
wider
lights
from
the
LEDs
can
create
a
brighter,
more
accurate
environment
at
night
that
more
closely
resembles
daylight.
C
The
next
couple
of
slides
has
some
examples
of
lights
that
we've
put
up
in
the
city.
This
slide
is
an
example
of
a
high-pressure
sodium
vs.
LED
light,
and
this
is
near
the
public
services
corporation
yard
on
huntington
avenue,
so
it's
pretty
clear
even
without
before-and-after
labels
that
which
one
is
the
before
and
which
one
will
be
the
after.
C
The
high-pressure
sodium
light
on
the
left
has
poor,
illumination
and
many
dark
spots,
making
pedestrians
and
cyclists
difficult
to
see
at
night
until
they're,
up
close
the
LEDs,
the
LED
light
on
the
right
site,
illuminates
the
whole
road
and
will
enable
a
clear
field
of
vision,
and
this
slide
just
illustrates
what
the
two
fixtures
look
like.
So
on.
The
left
is
the
current
high
pressure
sodium
lamp
and
on
the
right
is
an
LED
fixture.
So
you
notice
this
is
on
the
same
zoom,
so
the
LED
fixture
is
a
lot
smaller
than
the
high
pressure
sodium.
C
This
is
an
example
of
a
Demento
post-op
metal
halide
on
the
left
and
a
LED
retrofit
on
the
right,
while
the
illumination
difference
is
less
noticeable
here.
The
metal
halide
light
on
the
left
needs
a
far
greater
amount
of
power
than
the
LED,
so
the
energy
savings
will
still
be
substantial,
and
here
is
a
picture
of
the
two
fixtures,
so
you
might
notice
that
the
rachelle
will
be
the
same.
We
are
recommending
a
retrofit
fixture,
so
only
the
fixture
on
the
inside
will
be
changed
if
approved.
C
C
The
most
common
concern
from
the
feedback
received
was
a
residents
concerned
with
like
glaring
or
bleeding
into
their
homes
at
night.
So
during
the
installation
process,
if
approved,
these
potential
issues
can
be
mitigated
by
adjusting
the
LED
fixtures
to
a
degree,
but
if
further
action
needs
to
be
taken,
shields
can
also
be
installed
on
these
fixtures
to
prevent
the
bleeding
go
into
the
homes,
so
staff
released
an
rfp
in
September
and
based
on
the
proposals
receive
selected,
tanko
lighting
incorporated
as
the
most
qualified
vendor
for
this
project.
This
project
would
have
two
stages.
C
The
first
stage
will
include
the
vendor
performing
a
comprehensive
audit
of
the
city's
streetlights
and
holes
from
this
audit.
It's
estimated
that
about
30
poles
will
need
to
be
replaced
when
the
audit
is
completed.
The
audit
will
also
include
an
update
of
the
city
street
light
inventory,
as
this
current
inventory
that
the
city
utilizes
is
based
off
of
the
utility
bills.
It
will
also
include
populating
the
lights
into
our
GIS
system
to
to
improve
our
overall
infrastructure
mapping.
C
After
the
audit
is
completed,
a
plan
will
be
developed
to
replace
approximately
2100
streetlights,
with
the
majority
about
2000
being
the
Cobra
head
fixtures
and
the
rest
about
a
hundred
being
the
decorative
post-ops
on
san
mateo
avenue
and
Bay
Hill
Drive.
The
plan
will
most
likely
involve
converting
the
fixtures
in
sections
section
by
section
across
the
city,
but
that
will
be
finalized
when
the
audit
is
completed.
C
Should
the
council
or
anyone
from
the
public
wishes
to
view
them
stage.
Two
of
the
project
will
be
for
the
regulated
output
or
the
RO
circuits.
The
map
below
shows
the
locations
of
the
RO
circuits
across
the
city.
The
RO
circuits
are
on
a
series,
which
means
it's
a
string
of
lights
that
shares
the
same
power
source.
So
it's
similar
to
a
string
of
holiday
lights.
It
might
be
hard
to
see
on
the
map,
but
the
crest,
more
area,
ro
lights
are
highlighted
in
red.
C
The
diagram
on
the
left
side
shows
the
current
ro
set
up,
so
it's
typically
a
string
of
10
or
more
lights,
with
one
power
source,
that's
buried
in
the
ground.
So
in
order
for
in
order
to
deliver
enough
power
to
all
the
lights
within
the
series,
the
power
source
needs
to
deliver
enough
power
to
each
light,
which
means
that
each
lamp
in
this
each
lamp
in
the
series
can
carries
a
high
voltage.
C
So
currently,
if
the
bulb
goes
out
in
the
series,
the
entire
series
must
be
shut
off
in
order
to
deal
with
the
high
voltage.
As
mr.
razavi
mentioned
earlier,
the
cost
of
LED
fixtures
has
decreased
to
the
point
where
the
city
can
address
some
of
the
maintenance
issues
with
the
RO
lights,
with
a
temporary
solution
which
is
to
install
transformers
on
each
RL
circuit
light
to
eliminate
that
high
voltage.
So
the
animation
should
pop
up
here
so
once
the
transformers
are
installed.
C
The
transformers
would
save
a
substantial
amount
of
maintenance
time
through
historical
maintenance
records
that
we
keep.
We
estimate
that
about.
Eighty
percent
of
all
malfunctions
with
the
RO
circuits
are
due
to
the
to
the
lamp
itself,
so
this
would
save
a
suspension
amount
of
maintenance
time.
The
cost
to
install
these
transformers
is
approximately
two
hundred
thirteen
thousand
dollars.
C
However,
if
the
circuit
power
or
the
lines
underground
go
out,
the
entire
series
will
still
shut
off
until
the
problem
area
can
be
identified
and
repaired.
That
is
why
the
staff
still
recommends
that
the
RO
circuits
be
replaced
in
the
future
when
adequate
funding
sources
can
be
identified.
The
current
total
project
cost
estimate
for
replacing
the
entire
ro
series
in
the
city
is
approximately
two
to
three
million.
C
This
slide
shows
a
breakdown
of
the
proposed
project
costs.
It
includes
the
conversion
of
the
lights
for
the
cobra
heads
and
the
post-ops
also
the
installation
of
the
transformers,
and
it
also
includes
the
estimated
replacement
of
the
thirty
street
poles.
It
also
includes
a
ten
percent
contingency
and
about
34,000
for
staff
time.
Pg&Amp;E
rebates
are
expected
to
be
around
ninety
two
thousand
and
also
in
the
current
CIP
there's
already
a
ninety
one
thousand
seven
hundred
dollar
gas
tax
appropriation.
C
Borrowing
from
the
capital
reserves
will
result
in
the
lowest
project
costs
due
to
the
absence
of
interest
payments,
and
currently
there
is
about
6.5
million
in
the
capital
reserve.
Fund.
Payback
of
the
project
costs
will
be
through
the
energy
savings
that
can
be
achieved
through
the
conversion,
since
PG&E
new
rates
are
fixed
and
based
on
wattage,
the
energy
savings
will
be
seen
immediately
after
conversion
and
it's
estimated
to
be
about
a
hundred
thousand
a
year
and,
as
mr.
razavi
mentioned
earlier,
a
full
payback
of
the
project
kazakh
is
expected
within
nine
years.
C
C
Here
we
have
a
estimated
project
timelines
with
council
approval
tonight.
The
comprehensive
audit
would
take
place
in
April
to
Maine
and
with
the
followed
by
the
Cobra
head
post
hub
and
transformer
installations
expected
from
June
to
october,
and
again
we
recommend
replacing
the
RO
series
at
a
later
date
to
be
determined
once
funding
sources
can
be
identified.
C
D
You
mentioned
this,
the
series,
the
RO
fixtures
as
temporary
and
then
to
be
determined
when
to
spend
when
we
have
a
2
to
3
million
dollar
funding
source.
What,
if
we
don't-
and
what
is
temporary
and
tell
me
about
you-
know
assuring
us
that
the
crestmore
neighborhood
is
you
know,
is-
is
safe
to
have
you
know
ongoing
lighting,
even
with
these
new
transformers,
the.
B
B
But
but
the
rest
of
the
the
rest
of
the
city,
which
would
be
approximately
300
a
little
over
300
lights,
those
would
be
on
seven
circuits
and
those
circuits
will
still
will
have
problems
in
the
future.
However,
with
the
Transformers
would
take
care
of
approximately
eighty
percent
of
our
maintenance
follow
up
on
those
circuits.
In
other
words,
the
Transformers
would
make
the
streetlight
separate
from
the
circuit
itself,
so
the
streetlight
all
the
wiring,
the
streetlights,
would
be
normal.
Just
like
any
other
straight
line,
you
can
change
the
fixture.
B
You
can
put
the
LED
fixture
on
it.
There
will
be
any
no
problem
with
the
lights
popping
because
of
the
high
voltage
or
any
kind
of
fluctuation
and
the
voltage.
What
will
we
remain
is
from
the
streetlight
down
into
the
conduits
into
the
ground,
where
the
one
of
the
line
runs,
so
that
area
would
still
would
have
problems
in
the
future
until
we
do
a
replacement
project
once
the
finding
financing
I'm.
D
B
So
until
we
actually
take
these
lines
and
put
a
new
conduit
in
and
put
a
brand-new
wired
through
them,
they're
going
to
have
these
problems
and
the
issue
is,
you
know:
these
are
seven
different
locations
throughout
the
city
and
in
each
location
you
actually
have
to
cut
the
street
and
put
the
line
in
or
bury
it
behind
the
sidewalk.
So
we
have
to
make
sure
that
the
conduits
and
the
lines
are
done
so
either
through.
E
D
D
Other
question
is
I:
realize
we're
gonna,
have
all
these
cost
savings
and
pay
back
through
cost
savings
payback
through?
Do
we
have
a
paint
back
this
staff
has
financed?
Do
we
have
a
payback
plan?
I
mean
yeah
it
would
it
be
unreasonable
to
just
say,
let's
put
a
hundred
thousand
dollars
every
year
back
into
the
reserve.
I
mean
we
know
through
you
know
through
previous.
You
know,
communities
and
everything
that
we're
gonna
have
a
significant
savings,
and,
yes,
you
have
the
disclaimer
that
you
know
could
be
some
maintenance
here
there,
whatever.
B
Payback
councilmember
bar
is
actually
going
to
go
up
as
the
we're
based
on
the
ls2
rate,
as
it's
called
by
PG&E
and
it's
a
fixed
rate
per
streetlights
and
our
basic
street
lights.
For
example,
we
pay
close
between
five
to
six
dollars
per
month
per
street,
like
that's,
going
to
drop
down
to
about
two
to
three
dollars:
I'm
right,
bulleid,.
D
E
Yeah
I
do
like
that
yeah.
That
is
our
goal
at
your
end,
when
we
are
closing
the
books
to
actually
move
that
money
into
the
capital
reserve
first,
because
we
do
it
is
a
fixed
rate.
So
we
do
know
I
mean
just
to
give
you
an
idea.
Per
month,
we're
currently
paying
14,500
it'll
go
down
to
five
thousand
four
hundred
a
month
annually.
E
It's
1740
174,000
it'll
go
down
to
65,000,
so
that's
the
savings
of
109,000
the
first
year
and
we
anticipate
that
will
increase
so
and
then
that's
not
including
the
maintenance
costs
so
we'll
we'll,
monitor
and
finance,
we'll
leave
that
at
year-end.
So
if
you
want
to
put
it
in
the
resolution,
that's
fine,
but
we
plan
on
doing
it
anyway,
because
I
want
that
money
back.
A
F
Else
Michael
did
through
the
chair
just
to
follow
up
on
that
question.
So
currently
do
we
increase
X
I,
don't
recall
seeing
this
when
we
do
that
the
budget
and
is
there
an
annual
increase
that
we
allocate
for
the
the
increase
in
electrical
costs,
for
that
has
that
been
a
line
item
that
traditionally
goes
up
every
year.
E
Each
each
year
the
departments
are
charged
with
estimating
utility
costs,
electrical
costs
for
all
city
facilities,
including
the
streetlights
and
those
are
estimated
based
on
rate
information
and
the
utilization
and
historical
expenditure.
Information,
so
I
can't
say
that
they
have
always
gone
up,
but
they
are
analyzed
every
year
and
adjusted
accordingly.
Ok.
F
B
Correct
councilmember
cells
are,
we
are
to
monitor
the
maintenance.
These
lights
will
have
ten
year
warranty
on
the
parts
not
on
the
labor.
Labor
would
be
one
year
through
tanko,
but
ten
years
through
the
part,
so
we
expect
to
save
quite
a
bit
from
not
having
to
replace.
These
lights
was
usually
currently
last
between
three
to
five
years,
