additional

turn
lane,
while
a
performance
standard
requires
a
specific
level
of
performance
to
be
achieved
without
specifying
the
exact
physical
improvement(s)
needed
to
meet
the
standard.
As
stated
on
page
4.N-97,
an
“evaluation
of
engineering
design
considerations
to
mitigate
traffic
impacts
at
this
intersection
indicated
that
needed
improvements
might
not
be
feasible
without
removal
of
the
existing
median
at
this
location.”
To
provide
for
mitigation
of
intersection
operations
impacts,
rather
than
require
one
or
more
specific
physical
improvements,
such
as
adding
one
additional
northbound
left
turn
lane
(prescriptive
mitigation
measure),
Mitigation
Measure
allows
for
alternative
intersection
designs
that
might
allow
the
existing
median
to
remain.
However,
even
with
removal
of
the
median,
improvements
at
this
intersection
under
the
CPP
and
CPP-V
scenarios
would
result
in
LOS
D
traffic
conditions.

The
Draft
EIR
concludes
that
no
feasible
mitigation
measures
are
available
to
address
weekday
arena
traffic
from
a

event.
The
comment
correctly
notes
that
Mitigation
Measure
4.N-1d
at
Intersection
10,
Alana
Way/Harney
Way/Thomas
Mellon
Drive,
though
feasible,
is
under
the
jurisdiction
of
San
Francisco,
and
therefore
mitigation
implementation
cannot
be
assumed
and
a
significant
impact
is
unavoidable.
The
Draft
EIR
makes
no
assertion
as
to
whether
the
resulting
level
of
service
at
Intersection
10
is
“acceptable”
to
the
community.
The
determination
as
to
whether
Project
Site
development
traffic’s
contribution
to
traffic
at
this
intersection
is
“acceptable”
will
be
made
as
part
of
the
City’s
planning
review
and
decision
making
for
the
Baylands.
See

for
discussion
of
the
relationship
between
the
City’s
environmental
and
planning
reviews
for
the
Baylands.
See
also
6
for
discussion
regarding
the
differences
between
“significant
unavoidable”
and
“unacceptable”
impacts.
The
comment
correctly
notes
that
Mitigation
Measure
4.N-1e
at
Intersection
12,
Tunnel
Avenue/Bayshore
Boulevard,
is
subject
to
San
Francisco’s
approval
and
implementation.
As
a
result,
impacts
of
proposed
Baylands
development
are
significant
and
unavoidable.
