conditions
could
result
in
differing
rates
of
consolidation
if
not
addressed
appropriately.
However,
as
stated
in
this
paragraph
of
the
Draft
EIR,
“these
effects,
if
calculated
to
be
a
potential
hazard,
could
be
mitigated
as
part
of
the
final
site
design
through
widely
accepted
geotechnical
engineering
practices”
including
surcharging
techniques
that
accelerate
the
anticipated
consolidation
prior
to
construction
or
use
of
pile
foundations
that
are
anchored
in
more
competent
materials
at
depth.
These
techniques
are
widely
used
in
areas
of
similar
conditions
and
all
site-specific
development
would
be
required
to
adhere
to
building
code
requirements,
reducing
ground
settlement
impacts
to
less
than
significant.
See
for
discussion
regarding
the
adequacy
of
studies
for
use
in
the
Draft
EIR.
Studies
characterizing
wastes
within
the
landfill
and
the
soils
lying
on
top
of
the
landfill
were
conducted
subsequent
to
the
closure
of
the
Champion
Speedway,
and
would
therefore
account
for
any
contamination
caused
by
the
Speedway.

discussion
regarding
the
adequacy
of
studies
for
use
in
the
Draft
EIR.
While
the
Draft
EIR
identifies
remediation
technologies
that
have
been
proposed
to
date,
neither
the
RWQCB
nor
the
DTSC
have
approved
use
of
any
specific
technology
for
site
remediation.
Responsibility
for
approving
specific
requirements
for
Title
27
landfill
closure
rests
with
the
RWQCB.
It
is
neither
possible
nor
required
under
CEQA
for
the
Baylands
Draft
EIR
to
identify
all
possible
methods
that
may
be
considered
by
the
RWQCB
for
Title
27
landfill
closure.
See
1
for
discussion
regarding
the
programmatic
nature
of
the
Baylands
EIR
and
requirements
for
subsequent
environmental
review,
including
subsequent
environmental
for
site
remediation
and
Title
27
landfill
closure.
See
for
discussion
regarding
the
remediation
review
and
approval
process.
As
part
of
its
review
and
approval
of
Title
27
landfill
closure,
the
RWQCB
will
set
specific
requirements
for
the
materials
and
thickness
of
the
final
landfill
cap.
Based
on
currently
available
information,
the
visual
simulations
provided
in
Table
4.A-1
of
the
Draft
EIR
are
based
on
final
grades
within
the
former
landfill
that
provide
for
a
landfill
cap
and
site
grading
and
development
on
top
of
that
cap.
The
thickness
of
currently
proposed
engineered
fill
to
be
placed
within
the
former
railyard
is
based
on
required
grading
to
provide
for
drainage
and
site
development,
and
cannot
be
used
as
an
indication
of
the
thickness
of
the
final
landfill
cap.
See

for
discussion
regarding
compliance
with
the
law
as
mitigation
under
CEQA.
