Individual
Responses
to
Comments
from
Organizations
species
that
do
not
live
underwater
will
be
affected.
The
comment
does
not,
however,
identify
any
particular
species
or
noise
sensitivity
parameters.
Several
mitigation
measures
in
the
Draft
EIR
protect
terrestrial
wildlife
species
from
disturbance
from
construction
noise
and
associated
vibration,
including
Mitigation
Measures
4.C-1c,
4.C-1d,
and
4.C-1f,
which
all
require
preconstruction
surveys
for
sensitive
species
prior
to
initiation
of
any
ground
disturbing
activities.
These
measures
require
that
if
sensitive
species
are
detected,
the
species
would
be
protected
from
disturbance
with
buffers
and
construction
work
windows.
The
establishment
of
no-disturbance
buffers
would
function
to
protect
species
from
noise
and
vibration
impacts.
As
discussed
in
the
Draft
EIR,
tidal
marsh
habitat
features
are
located
around
the
perimeter
of
Brisbane
Lagoon,
and
consist
of
highly
fragmented,
isolated
areas
susceptible
to
predator
and
human
access.
In
light
of
these
conditions,
tidal
marsh
areas
are
unlikely
to
support
special
status
species
that
would
nest
in
this
habitat
type.
Tidal
marsh
habitat
is
depicted
on
Draft
EIR
Figure
4.C-1;
however,
precise
dimensions
of
these
habitat
types
were
not
included
in
the
Draft
EIR
because
they
fall
within
the
Lagoon
and
lagoon
perimeter
acreage
area
is
provided
in
Section
(page
of
the
Draft
EIR
Project
Description,
which
identifies
the
size
of
the
Lagoon
and
lagoon
perimeter
(defined
as
the
area
bounded
by
the
rights-of-way
of
Lagoon
Road,
Sierra
Point
Parkway,
and
the
Caltrain
rail
line),
as
being
136.6
acres,
including
119
acres
of
open
water
subject
to
muted
tidal
influence
and
an
additional
17.6
acres
of
lagoon
perimeter.
See
also
revised
Figure
4.C-1.
Physical
alterations
to
the
Brisbane
Lagoon
are
not
proposed
under
any
Project
Site
development
scenario.
In
the
absence
of
a
specific
proposal
that
would
affect
waters
of
the
Brisbane
Lagoon,
it
is
not
possible
to
speculate
regarding
coordination
with
federal
agencies
related
to
such
alterations.
Mitigation
Measure
4.C-1
requires
implementation
of
an
on-going
maintenance
plan
to
ensure
no
reduction
in
water
and
environmental
quality.
In
addition,
the
Draft
EIR
includes
performance
standards
that
stipulate
no
in-water
construction
and
no
development
at
the
Lagoon
beyond
passive
trail
uses
and
fishing.
This
performance
standard
avoids
significant
impacts
to
aquatic
species,
and
therefore
baseline
studies
of
lagoon
water
quality
were
unnecessary.
Monitoring
requirements
are
set
forth
in
the
Mitigation
Monitoring
and
Reporting
Program,
Chapter
4.0
of
the
Final
EIR.
Potential
contamination
of
the
Lagoon
by
the
former
landfill
is
an
existing
condition,
and
not
a
result
of
proposed
development
within
the
Baylands.
