Individual
Responses
to
Comments
from
Organizations
and
approaching
vehicle
drivers
to
see
each
other
when
vehicles
parked
in
a
parking
lane
would
otherwise
block
visibility.
The
Specific
Plan
also
proposes
one,
pedestrian
overcrossings
over
the
Caltrain
right-of-way
and
Tunnel
Avenue
for
pedestrians
and
bicyclists
along
the
Geneva
Avenue
extension
and
Roundhouse
Street
in
addition
to
the
overpasses
at
the
existing
and
proposed
relocated
Caltrain
platform
(see
Figure
4.N-17).
While
the
proposed
overcrossings
would
not
result
in
any
significant
impacts
to
pedestrian
or
bicycle
access,
as
determined
in
the
Draft
EIR,
whether
additional
overcrossings
would
be
desirable
to
promote
pedestrian
movement
within
the
Baylands
will
be
considered
as
part
of
the
City’s
planning
review
and
decisionmaking.
Wind
data
for
the
Baylands
Project
Site
indicate
that
winds
from
the
west
and
northwest
blow
more
than
75
percent
of
the
time
and
calm
wind
scenarios
only
occur
13
percent
of
the
time.
Consequently,
the
pollutants
are
dispersed
primarily
to
the
east
out
over
San
Francisco
Bay.
Heavier
pollutants
such
as
particulate
matter
could
eventually
be
deposited
into
the
Bay.
Other
pollutants
such
as
ozone
precursors
could
be
transported
into
the
atmosphere
under
warmer
conditions
and
combine
to
form
ozone.
The
Draft
EIR
identified
significant
and
unavoidable
construction-related
and
operational
air
quality
impacts
would
result
from
implementation
of
all
four
development
scenarios.
Thresholds
applied
in
the
assessment
of
impact
significance
in
the
Draft
EIR
were
derived
by
BAAQMD
based
on
federal
and
state
Clean
Air
Act
stationary
source
limitation
levels
for
non-attainment
pollutants
and
precursors
and
represent
what
would
constitute
cumulatively
considerable
contributions
to
air
quality.
The
health
implications
of
this
significant
impact
would
consist
of
the
potential
for
increased
violations
of
the
air
quality
standards
for
ozone
and
particulate
matter
(both
PM10
and
PM2.5).
As
stated
on
Draft
EIR
page
4.B-2,
elevated
ozone
concentrations
can
cause
eye
irritation,
airway
constriction,
and
shortness
of
breath
and
can
aggravate
existing
respiratory
diseases
such
as
asthma,
bronchitis,
and
emphysema.
As
stated
on
page
4.B-5
of
the
Draft
EIR,
both
long-term
and
short-
term
exposure
to
PM
2.5
can
cause
a
wide
range
of
health
effects
(e.g.,
aggravating
asthma
and
bronchitis,
causing
visits
to
the
hospital
for
respiratory
and
cardiovascular
symptoms,
and
contributing
to
heart
attacks
and
deaths).
The
extent
to
which
these
significant
emissions
would
result
in
adverse
health
effects
is
not
readily
quantifiable
on
a
regional
scale.
