however,
existing
transit
service,
rather
than
future
transit
expansion,
was
used
for
the
calculation
in
order
to
provide
a
conservative
internal
capture
reduction.
The
traffic
impact
analysis
uses
commonly
accepted
methods
of
systematically
determining
traffic
impacts
of
a
proposed
development
project.
The
Draft
EIR
follows
this
traffic
impact
analysis
process,
and
the
results
are
presented
starting
on
page
4.N-89,
Project
Impacts
and
Mitigation
Measures
.
The
existing
operational
performance
of
US
101
is
presented
starting
on
page
4.N-7,
Freeway
Mainline
Operations.
Impacts
to
US
101,
from
Baylands
site
traffic
and
other
proposed
and
approved
development
projects
under
existing
and
cumulative
conditions,
are
presented
in
Tables
4.N-28
(page
4.N-105)
and
4.N-33
(page
4.N-125).
The
comment
is
correct
that
the
widening
of
US
101
has
not
been
studied
as
part
of
this
Draft
EIR.
Impacts
to
freeway
mainline
segments
are
based
on
the
existing
configuration
of
the
freeway,
since
Caltrans
has
no
plans
for
widening
the
US
101
freeway.
The
addition
of
HOV/HOT
lanes
from
the
San
Francisco
County
border
to
Whipple
Avenue
(southern
San
Mateo
County)
are
part
of
Caltrans
District
4
Transportation
System
Development
Plan
(2011),
but
is
neither
planned
nor
funded.
See
for
discussion
of
internal
trip
capture.
The
comment
suggests
an
internal
shuttle
that
serves
the
southern
portion
of
the
site,
but
does
not
specify
the
impact
to
be
mitigated.
An
internal
shuttle
would
be
considered
as
a
part
of
the
TDM
program
or
as
a
part
of
the
project-level
review
for
specific
development
proposals.
The
southern
portion
of
the
site
in
the
DSP
and
DSP-V
scenarios
is
connected
to
the
balance
of
the
Baylands
via
Sierra
Point
Parkway
and
Tunnel
Avenue.
In
addition,
a
retail
area
is
proposed
in
the
southeastern
portion
of
the
site
that
would
be
a
prime
candidate
for
providing
the
types
of
commercial
services
that
might
be
frequented
by
employees
of
the
area.
Use
of
traffic
models
to
forecast
traffic
that
would
be
generated
by
large-scale
projects,
such
as
General
Plan
amendments
and
updates,
specific
plans,
and
developments
for
which
specific
commercial,
office,
or
residential
tenants
cannot
be
known
at
the
time
of
analysis
has
long
been
commonly
accepted
as
the
only
viable
methods
of
analyzing
the
impacts
of
such
projects.
As
stated
on
pages
4.N-71
to
4.N-84
of
the
Draft
EIR,

generation
estimates
