It
appears
that
approximately
40
of
the
points
measured
in
the
wind
tunnel
study
for
the
Draft
EIR
lie
within
the
“practical
sailing
area”
(PSA)
identified
in
Comment
CPA-2.
Figure
11,
WNW
Wind

in
Draft
EIR
Appendix
J.1
shows
that
the
points
cited
by
CPA
are
in
the
west-southwest
portion
of
the
PSA.
Figure
11
also
shows
that
at
the
other
28
points
to
the
north
in
the
PSA,
the
winds
would
be
unaffected
by
Project
Site
development.
Furthermore,
the
northwest
portion
of
the
PSA
also
would
be
unaffected
by
Project
Site
development
for
WNW
winds,
because
it
is
not
downwind
of
the
Baylands
site
for
WNW
winds.
New
measurements
in
the
northwest
portion
of
the
PSA,
closer
to
the
freeway,
would
not
change
that
fact.
CPA
Figures
9
and
10
imply
that
there
is
little
or
no
valid
information
about
wind
effects
in
the
PSA
for
Northwest
winds.
It
seems
to
imply
that
a
Northwest
wind
–
a
wind
that,
by
definition,
flows
from
the
northwest
toward
the
southeast
–
could
flow
over
the
Baylands
site
and
then,
somehow,
affect
wind
conditions
in
the
northeast
quadrant
of
the
PSA.
Consider
a
“stream-line”
of
NW
wind.
If,
on
one
hand,
it
passes
over
the
center
of
the
Baylands
Site,
it
would
not
cross
the
“practical
sailing
area”
but
would
pass
over
the
southern
portion
of
the
grid.
On
the
other
hand,
if
the
NW
wind
passes
over
the
northern-most
tip
of
the
Baylands
site,
it
would
have
a
relatively
long
distance
to
travel
over
land,
including
the
freeway
and
the
off-ramp,
before
it
could
reach
the
waters
of
the
Bay.
However,
the
NW
winds
that
would
most
affect
the
largest
fraction
of
the
“practical
sailing
area”
would
pass
over
the
Little
Hollywood
neighborhood,
Bayview
Hill,
and
the
Executive
Park
developments
in
San
Francisco.
For
these
reasons,
the
overall
wind
effects
of
development
on
the
“practical
sailing
area”
are
reasonably
characterized
by
the
data
and
analysis
in
the
Draft
EIR.
(See

With
respect
to
Project
Site
development’s
effects
on
the
“practical
sailing
area”
with
a
West
wind,
most
of
the
effects
on
the
“practical
sailing
area”
would
result
from
proposed
Project
Site
development.

In
the
area
between
the
data
points
on
CPA
Figure
11
and
the
western
shore
of
the
Bay,
the
transect
testing
discussed
in
and
provides
evidence
of
the
lowered
wind
speed
that
now
occurs
over
the
“wind
shadow”
area
at
the
shoreline
and
out
to
750
feet
from
the
shore.
Beyond
that,
the
wind
speeds
increase
with
the
distance
travelled
over
water.
With
the
Project,
a
further
decrease
in
wind
speed
of
approximately
4%
to
6%
due
to
the
buildings,
offset
by
a
2%
to
4%
recovery
of
speed
due
to
removal
of
trees
along
the
roadways,
could
occur
close
inshore
