Individual
Responses
to
Comments
from
Organizations
(Mitigation
Measure
4.J-3b),
and
reduce
construction
noise
impacts
to
existing
and
proposed
receptors
(Mitigation
Measure
4.J-4a
and
4.J-4b).
Both
the
DNL
and
CNEL
noise
descriptors
are
defined
on
Draft
EIR
page
4.J-3.
The
Draft
EIR
uses
both
descriptors
because
the
FAA
uses
the
DNL
for
its
criterion
related
to
aircraft
noise,
while
the
State
of
California
uses
the
CNEL
for
its
criterion
related
to
aircraft
noise.
Except
under
unusual
circumstances
the
calculated
CNEL
and
DNL
are
very
similar
and,
as
demonstrated
in
Table
4.J-1,
they
differ
by
no
more
than
1
dBA.
A
third
party
acoustical
consultant
was
retained
to
consider
the
acoustical
effects
of
Brisbane’s
topography
and
the
effects
it
may
have
on
the
analysis
of
noise
impacts
of
the
Draft
EIR.

Response
The
significance
threshold
used
to
evaluate
the
impact
of
proposed
Baylands
development
is
discussed
in
detail
in
which
also
discusses
the
ability
of
the
lead
agency
to
define
significance
thresholds
under
CEQA.
There
are
no
known
critical
thresholds
in
wind
speed
or
wind
speed
reduction
that
cause
a
substantial
degradation
of
the
CPSRA
windsurfing
resource
(see
Draft
EIR
page
4.M-11).
The
thresholds
offered
in
the
“Required
Conditions”
as
defined
by
the
CPA
comment
letter
(CPA2)
are
subjective
and
conflate
considerations
of
gust
and
lull
wind
speeds,
which
are
weather
phenomena
not
related
to
proposed
Project
Site
development,
with
the
wind
speed
and
turbulence
caused
by
changes
in
surface
roughness
at
the
Baylands
Project
site.

discussion
The
first
paragraph
under
“Roadway
Network”
on
Draft
EIR
page
4.N-1
is
revised
to
read
as
follows:
This
subsection
describes
the
freeways
and
streets
that
provide
vehicle
access
and
circulation
within
the
Project
Site
and
vicinity
(see
Figure
4.N-1
and
Figure
4.N-2
).
Cumulative
projects
are
described
in
Chapter
6
(see
Figure
6-1A
for
the
locations
of
these
cumulative
projects).
With
the
exception
of
the
freeways,
each
of
the
facilities
described
in
this
subsection
also
provides
the
primary
means
of
bicycle
and
pedestrian
circulation
(described
in
greater
detail
in
the
subsections
describing
travel
by
those
modes).
Study
intersections
were
identified
by
the
City
of
Brisbane
as
lead
agency
at
the
time
of
the
NOP
to
fully
capture
the
impacts
of
Project
Site
development.
The
intersections
were
selected
based
on
traffic
patterns,
modeling
results,
and
engineering
judgment.
