Individual
Responses
to
Comments
from
Organizations
designed
based
on
the
results
of
the
soil
corrosivity
testing
and
subsequent
recommendations
of
the
manufacturer
or
a
corrosion
engineer.
The
City
Engineer
would
approve
all
final
design
and
engineering
plans
prior
to
any
construction.”
As
described
above,
and
in
compliance
with
the
California
Building
Code,
geotechnical
investigations
(design
level
geotechnical
report
mentioned
above)
would
evaluate
existing
site
soils
and
any
related
constraining
qualities
such
as
corrosiveness,
and
would
specify
engineered
backfill
and
other
corrosive-
resistant
materials
to
mitigate
potential
impacts
to
project
utilities
from
soil
materials.
All
final
design
and
engineering
plans
required
to
be
submitted
by
a
licensed
geotechnical
engineer
would
be
subject
to
review
and
approval
by
the
City
Engineer,
as
discussed
in
the
Draft
EIR
Impact
4.E-2
and
Mitigation
Measure
4.E-2a.
Mitigation
Measure
4.E-2a
requires
design
plans
for
underground
utilities
within
the
Baylands
would
be
required
to
account
for
site-specific
conditions,
such
as
potential
ground
settlement
and
shifting.
The
water
supply
proposed
for
Baylands
development
is
the
proposed
transfer
of
water
supply
from
the
Oakdale
Irrigation
District.
The
water
supply
assessment
and
evaluation
in
Section
4.O
of
the
Draft
EIR
determined
that
the
proposed
water
supply
agreement
provided
an
assured
supply
of
water
for
proposed
development
of
the
Baylands.
In
the
unlikely
event
that
the
Brisbane
City
Council
would
approve
development
of
the
Baylands
in
the
absence
of
a
water
supply
agreement
to
provide
potable
water
to
support
Baylands
development,
a
significant
unavoidable
impact
would
result.
The
Draft
EIR
does
not
speculate
as
to
what
the
water
supply
for
the
Baylands
would
occur
should
such
an
action
be
taken.
This
comment
raises
issues
about
the
SFPUC
existing
Southeast
Treatment
Plant.
The
SFPUC
provides
wastewater
treatment
service
to
the
portion
of
Brisbane
that
includes
the
Baylands
Project
Site.
The
project
does
not
involve
changes
in
the
SFPUC’s
facilities
or
operations;
the
SFPUC
has
embarked
on
its
own
improvement
program
for
its
Southeast
Treatment
Plant
(http://sfwater.org/index.aspx?page=616).
There
is
no
basis
to
support
the
comment
assertion
that
“a
new
facility
must
be
built.”
For
proposed
Baylands
development,
as
described
in
Chapter
3,
Project
Description
,
and
as
analyzed
on
pages
4.O-44
to
4.O-47,
proposed
Project
Site
development
includes
the
construction
of
a
recycled
water
plant
that
would
treat
a
portion
of
Project
Site
development’s
wastewater
to
provide
recycled
water
for
irrigation
use
within
the
Baylands.
Until
the
recycled
water
plant
is
constructed,
all
wastewater
flows
would
be
discharged
to
the
existing
Bayshore
Sanitary
Brisbane
Baylands
