The
2004
American
Association
of
State
Highway
and
Transportation
Officials
(AASHTO)
guidelines
include
references
for
underground
utility
criteria,
citing
studies
that
indicate
vibration
under
the
ground
surface
is
lower
than
that
measured
at
the
ground
surface.
One
major
utility
(AASHTO
2004)
has
adopted
a
criterion
of
4.0
in/sec
(100
mm/s)
for
underground
optical-fiber
cables.
Underground
or
restrained
concrete
structures
can
withstand
vibration
of
10.0
in/sec
(254
mm/s)
before
the
appearance
of
threshold
cracks.
Thus,
underground
utilities
are
less
sensitive
than
surface
structures.
As
discussed
on
Draft
EIR
page
4.J-22,
pile
driving
can
result
in
peak
particle
velocity
(PPV)
of
up
to
1.5
in/sec
at
a
distance
of
25
feet
(FTA,
2006),
but
typically
average
about
0.644
PPV
at
that
distance.
All
other
construction
activities
would
have
substantially
lower
vibration
inducing
potential.
Vibration
from
pile
driving
could
potentially
reach
levels
in
excess
of
the
4.0
in/sec
AASHTO
criteria
at
distances
between
10
to
15
feet.
Consequently
additional
mitigation
measures
are
identified
to
implement
alternatives
to
impact
pile
driving,
as
needed.
The
PG&E
natural
gas
pipeline
running
within
the
Bayshore
Boulevard
right-of-
way
and
the
Kinder
Morgan
tank
farm
are
existing
uses
whose
operations
are
subject
to
federal,
state,
and
local
requirements
to
ensure
public
safety.
They
are
not
part
of
the
development
proposed
for
the
Baylands.
See
for
discussion
of
land
use
compatibility
between
proposed
development
in
the
Baylands
and
the
Kinder
Morgan
tank
farm.

Any
sureties
or
performance
bonds
related
to
site
remediation
would
fall
under
the
regulatory
authority
of
the
RWQCB
and
DTSC.
The
Mitigation
Monitoring
and
Reporting
Program
set
forth
in
Chapter
4.0
of
the
Final
EIR
contains
provisions
to
ensure
implementation
of
EIR
mitigation
measures.
The
roadway
facilities
analyzed
in
the
Draft
EIR
are
described
in
Section
4.N,
Traffic
and
Circulation
.
As
discussed
in
that
Section,
the
Candlestick
interchange
is
proposed
to
be
