therefore
also

This
comment
does
not
raise
any
significant
environmental
issues
regarding
the
adequacy
of
the
EIR
or
its
analysis
and
conclusions.
All
buildings,
including
proposed
multi-story
buildings,
as
well
as
proposed
grading,
the
topography
of
the
Baylands
and
vicinity,
were
modeled
for
each
scenario
evaluated
in
the
Draft
EIR.
A
description
of
the
model
is
provided
on
Draft
EIR
page
4.M-12.
Additional
information
regarding
wind
analysis
conducted
for
the
Draft
EIR
is
provided
in
through
The
wind
analysis
focused
on
the
wind
effects
of
Project
Site
development
within
the
CPSRA,
and
did
not
measure
wind
effects
near
street
level
that
might
occur
within
the
interior
of
the
Project
site.
The
thresholds
of
significance
used
to
analyze
air
quality
impacts
are
identified
on
page
4.B-15,
and
does
not
include
potential
wind
tunnel
effects
of
tall
buildings
within
the
Baylands.
Such
effects
are
dependent
upon
the
height,
size,
and
location
of
buildings
in
relation
to
prevailing
winds
and
other
buildings,
and
cannot
be
accurately
evaluated
without
site-specific
information
on
the
design
and
locations
of
buildings,
which
is
not
possible
at
this
programmatic
stage
of
review.
Winds
vary
at
pedestrian
levels
within
an
urban
area.
Development
patterns
--
including
street
and
building
orientation
with
respect
to
prevailing
wind
directions
--
building
heights,
and
building
massing
can
affect
the
winds
experienced
at
the
pedestrian
level.
Wind
speeds
are
generally
greater,
on
average,
along
streets
that
are
oriented
parallel
to
the
prevailing
wind
direction
(in
the
case
of
the
Baylands
Site,
this
orientation
would
be
West-East
or
West
Northwest-South
Southeast).
Wide
streets
bordered
by
tall
buildings
are
especially
vulnerable
to
the
funneling
effects
that
result
when
streets
are
oriented
parallel
to
prevailing
wind
directions.
The
impact
of
wind
funneling
can
often
be
reduced
by
the
presence
of
tall,
bushy
trees
along
streets
susceptible
to
wind
to
force
the
wind
to
stay
above
street
level.
Winding
streets
and
streets
oriented
perpendicular
to
the
prevailing
wind
direction
tend
to
have
lighter
winds
at
pedestrian
level.
Building
height,
massing,
and
orientation
also
affect
ground-
level
wind
accelerations.
Tall,
slab-like
buildings
tend
to
deflect
wind
downward.
As
wind
flow
comes
over
the
edge
of
a
roof
or
around
a
corner,
it
separates
into
streams
at
about
three-quarters
of
the
building
height.
Above
this,
