under
a
broad
range
of
hydrological
conditions
in
order
to
refine
the
operational
rules,
understand
the
potential
water
losses
of
the
OID
transfer
amount,
and
ensure
that
the
transfer
does
not
adversely
affect
MID
or
SFPUC
system
operations
or
customer
deliveries.
Alternatives
CEQA
requires
an
EIR
to
evaluate
alternatives
to
a
project
that
would
reduce
or
avoid
significant
effects
while
attaining
most
of
the
basic
project
objectives.
Because
none
of
the
development
scenarios
evaluated
in
the
Draft
EIR
would
result
in
significant
water
supply-related
effects,
the
Draft
EIR
did
not
evaluate
a
“water
supply
alternative.”
One
significant
impact
was
identified
associated
with
the
2.0-mgd
flow
reduction
on
the
stretch
of
the
Tuolumne
River
between
Hetch
Hetchy
Reservoir
and
Don
Pedro
Reservoir,
and
Mitigation
Measure
4.O-1
is
identified
to
reduce
that
impact
to
a
less-than-significant
level.
However,
several
water
supply
options
were
investigated
during
the
Brisbane
Baylands
project
development
phase
before
the
proposed
OID
water
transfer
was
incorporated
into
the
project.
Those
efforts
did
not
identify
another
viable
supply
option.
Supply
options
investigated
are
summarized
below.
Other
Supply
Options
The
Project
Sponsor,
UPC,
investigated
a
range
of
options
for
securing
adequate
water
supply
for
the
Project.
These
options
fall
in
to
three
general
categories:
(1)
secure
supply
from
another
SFPUC
wholesale
customer
in
the
Bay
Area
already
served
by
the
SFPUC’s
regional
water
system
and/or
overlying
the
Westside
Groundwater
Aquifer,
(2)
import
supply
from
an
outside
entity
via
a
water
transfer
arrangement
and
wheel
the
water
through
the
SFPUC
regional
water
system
to
Brisbane,
and
(3)
participate
with
others
in
development
of
a
local/Bay
Area
desalination
facility.
UPC
held
discussions
with
several
agencies
as
follows:
Other
SFPUC
Wholesale
Customers
:
California
Water
Service
Company
(CalWater),
City
of
Palo
Alto,
City
of
Hayward,
City
of
Colma,
City
of
San
Bruno,
Alameda
County
Water
District.
Water
Transfer/Supply
Import
:
Modesto
Irrigation
District,
Turlock
Irrigation
District,
East
Bay
Municipal
Utility
District.
Desalination
:
CalWater.
In
each
case,
none
of
these
options
was
found
to
be
viable,
largely
because
the
agency
controlling
the
potential
supply
either
was
not
interested
or
did
not
have
sufficient
supply
to
meet
Brisbane’s
need.
With
respect
to
a
desalination
project
concept
to
develop
a
new
facility
on
the
northern
Peninsula
to
generate
a
new
supply
for
the
area,
CalWater
expressed
some
interest
in
such
a
project,
but
there
is
no
specific
project
development
effort
underway;
thus,
this
remains
a
speculative
option
(Duane
Morris
memo,
March
26,
2012).
