bulk
of
the
site
is
comprised
of
fill
consisting
of
earthquake
rubble,
landfill
debris,
and
soil.
As
noted
in
this
comment,
the
Draft
EIR
makes
clear
that
soil
borings
will
be
necessary
to
establish
adequate
foundations
for
buildings.
To
the
extent
that
determining
requirements
for
adequate
building
foundations
requires
establish
how
and
where
there
is
communication
between
the
various
water-bearing
units,
building
foundation
analyses
will
provide
the
requested
information.
In
addition,
to
the
extent
that
site
remediation
under
the
regulatory
authority
of
the
RWQCB
and
DTSC
requires
establishing
how
and
where
there
is
communication
between
the
various
water-bearing
units,
the
requested
information
will
be
provided
as
part
of
remedial
action
plans
and/formal
landfill
closure
plans.
The
Draft
EIR
statement
cited
in
this
comment
was
based
on
the
numerous
hazardous
materials
studies
completed
within
the
Baylands
Project
Site
over
the
years.
These
studies
are
provided
in
the
Draft
EIR
Appendix
H.
The
soils
referred
to
in
this
comment
were
placed
as
the
result
of
an
ongoing
soils
processing
operation
on
the
former
landfill
that
predates
studies
of
waste
characterization
within
the
former
landfill.
No
evidence
has
been
provided
or
is
known
that
soils
processing
has
altered
the
thickness
of
wastes
within
the
landfill
or
altered
its
characteristics.
Formal
closure
of
the
former
landfill
under
the
regulatory
authority
of
the
RWQCB
will
address
anticipated
compaction,
including
compaction
from
future
grading
and
building
construction.
Draft
EIR
Section
4.E,
Geology,
Soils,
and
Seismicity
,
and
Section
4.H,
Surface
Water
Hydrology
and
Water
Quality
,
demonstrate
a
functional
understanding
of
the
geology
and
hydrology
geology
of
the
Baylands
Project
Site
appropriate
to
the
programmatic
nature
of
the
Draft
EIR.
See
1
for
discussion
of
program
versus
project
analyses.
Additional
site-specific
geologic
and
soils
studies
will
be
required
as
part
of
landfill
closure
activities
and
site-specific
development
projects
within
the
Baylands.
As
stated
in
the
Draft
EIR
on
pages
4.E-44
through
4.E-47,
there
are
a
number
of
geotechnical
approaches
(e.g.,
surcharging,
deep
foundation
systems,
dynamic
compaction,
etc.)
that
are
available
to
address
settlement
hazards
prior
to
building
construction.
In
accordance
with
current
building
code
requirements
and
site
specific
geotechnical
design
recommendations,
site
preparations
and
foundation
design
would
occur
at
such
time
as
specific
building
design(s)
are
prepared
prior
to
