The
City
College
fault
is
not
categorized
as
an
active
fault
(i.e.,
shown
evidence
of
displacement
within
last
11,000
years)
by
the
California
Geological
Survey.
Active
faults
are
generally
considered
to
have
the
highest
probability
for
causing
a
significant
earthquake,
and
in
accordance
with
the
seismic
design
criteria
of
the
California
Building
Code
(CBC),
all
proposed
improvements
would
be
required
to
consider
the
anticipated
groundshaking
that
could
occur
from
a
maximum
credible
earthquake
3
considering
a
site’s
location
relative
to
act
ive
faults
in
the
region.
As
stated
on
page
4.E-
37
of
the
Draft
EIR,
“Chapter
16,
Section
1613
of
the
CBC
provides
earthquake
loading
specifications
for
every
structure
and
associated
attachments
that
must
also
meet
ASCE
07-
05.”
This
approach
considers
the
best
science
available
on
seismic
design
and
requires
that
structures
incorporate
these
design
measures
that
meet
or
exceed
these
building
code
requirements
in
order
to
minimize
any
potential
damage
or
injury
that
could
occur
from
a
major
earthquake.
The
Draft
EIR
concludes
on
page
4.E-40
that
with
the
inclusion
of
Mitigation
Measures
4.E-2a
and
4.E-2b,
impacts
related
to
strong
seismic
groundshaking
associated
with
Project
Site
development
would
be
reduced
to
less-than-significant
levels.
Mitigation
Measures
4.E-2a
requires
compliance
with
current
California
Building
Code
requirements
including
Chapter
16,
Section
1613
in
relation
to
grading
activities,
fill
placement,
soil
corrosivity/expansion/erosion
potential,
compaction,
foundation
construction,
drainage
control
(both
surface
and
subsurface),
and
avoidance
of
settlement,
liquefaction,
differential
settlement,
and
seismic
hazards.
Mitigation
Measures
4.E-2b
addresses
possible
corrective
actions
that
might
need
to
be
taken
in
relation
to
the
former
landfill
following
a
major
earthquake.
See

a
discussion
of
the
adequacy
of
the
CBC
as
mitigation
for
seismic
hazards.

Review
Process
and
Responsibilities
for
Site
Remediation
and
Title
27
Landfill
Closure
Comments
A
number
of
comments
questioned
the
review
process
and
responsibilities
for
site
remediation
and
Title
27
landfill
closure.
The
purpose
of
this
Master
Response
is
to
identify
responsibilities
and
requirements
for
site
remediation
and
Title
27
landfill
closure.
Response
“Remedial
action”
or
“remediation”
refers
to
required
actions
to
prevent,
minimize,
or
mitigate
damage
that
may
result
from
the
release
or
threatened
release
of
hazardous
materials.
These
actions
include
site
cleanup,
including
excavation
and
disposal
of
soils,
pumping
and
treating
of
groundwater,
removal
of
leachate
and
volatiles,
in
situ
treatment
of
appropriate
media,
and
placing
restrictions
on
the
land
use
after
completion
of
remediation.

A
maximum
credible
earthquake
is
a
technical
term
that
defines
the
largest
earthquake
capable
of
occurring
under
the
known
tectonic
framework
for
a
specific
fault
or
seismic
source,
as
based
on
geologic
and
seismologic
data.
