Again,
when
the

the
Bay,
the
lesser
surface

of
the

will
enable
the

to

which
can
be
seen
in

no

The

on

wind
resources
of
the
CPSRA,
as

There
is
no
evidence
that
the
“Sailable
Day
Impact
Analysis”
can
reliably
determine
the
impact
on
the
CPSRA
windsurfing
resource
due
to
Project
Site
development.
As
described
further
the
suggested
alternative
wind
analysis
considers
wind
lulls
and
gusts
that
are
not
affected
by
Project
Site
development
and
evaluates
data
with
an
unknown
calibration
and
correlation
to
the
Resource
against
absolute
thresholds
of
significance,
referred
to
as
“Required
Conditions”
as
defined
in
the
comment
letter,
that
are
not
demonstrated
to
be
necessary
and/or
appropriate
for
all
users
of
the
CPSRA
windsurfing
resource.
See
for
additional
detail
regarding
this
topic.
In
contrast
to
the
threshold
of
significance
used
in
the
Draft
EIR,
the
threshold
of
significance
suggested
by
CPA
appears
not
to
have
been
previously
used
in
an
EIR
to
evaluate
the
wind
impact
of
a
proposed
project
on
the
CPSRA
windsurfing
resource
(see
