The
nearest
off-site
sensitive
receptor
referred
to
here
is
on
Desmond
Street
and
in
the
Little
Hollywood
neighborhood
of
San
Francisco.
The
mitigation
measures
on
Draft
EIR
page
4.J-25
are
identified
to
address
vibration
impacts.
Sound
monitoring
and
recording,
as
suggested
in
this
comment,
would
not
serve
to
reduce
vibration
levels.
Mitigation
measure
4.J-2a
establishes
a
vibration
performance
standard
to
be
applied
to
proposed
residential
development
in
the
DSP
and
DSP-V
scenarios.
To
ensure
proposed
residential
development
in
the
DSP
and
DSP-V
scenarios
meets
those
requirements,
the
developer
would
be
required
to
prepare
an
acoustical
study
that
would
be
verified
by
the
City’s
Building
Department.
Mitigation
measure
4.J.2b
requires
the
developer
to
prepare
Pre-Construction
Assessment
to
Minimize
Structural
Pile-Driving
Vibration
Impacts
and
establishes
performance
standards
to
protect
historic
structures.
A
text
revision
is
hereby
added
to
Mitigation
Measure
4.J-3b
on
Draft
EIR
page
4.J-31,
based
on
recommendations
of
the
Renewable
Energy
Research
Laboratory
(RERL,
2004):
Mitigation
Measure
4.J-3b:
Small
wind
turbines
shall
be
sited
a
minimum
of
50
feet
from
the
property
line
of
noise
sensitive
land
uses
(e.g.,
residential,
schools,
religious
institutions).
,
and
uUtility
scale
wind
turbines
shall
be
csited
a
minimum
of
100
feet
from
the
property
line
of
noise
sensitive
land
uses
and
separated
from
one
another
by
a
distance
no
less
than
a
minimum
of
two
times
the
rotor
diameter
of
the
larger
turbine.
The
data
presented
in
Draft
EIR
Table
4.J-7
presents
noise
generation
by
construction
phase
for
the
information
of
the
reader.
The
pile
driving
noise
generation
estimates
of
this
table
are
also
corroborated
by:
Federal
Transit
Administration
(FTA),
Transit
Noise
and
Vibration
Impact
Assessment
,
May
2006.
California
Department
of
Transportation
(Caltrans),
Technical
Noise
Supplement
to
the
Traffic
Noise
Analysis
Protocol
,
September
2013.
Additionally,
as
stated
on
Draft
EIR
page
4.J-12,
to
further
define
the
level
of
pile-driving
noise,
monitoring
was
conducted
during
pile-driving
activities
at
Sierra
Point
in
Brisbane,
approximately
one
mile
southeast
of
the
Baylands
site
where
soil
conditions
could
be
similar
to
conditions
at
the
Baylands
site.
Maximum
noise
levels
monitored
were
91
dBA
at
a
distance
of
200
feet,
which
is
consistent
with
the
data
presented
in
Table
4.J-7.
