Individual
Responses
to
Comments
from
Organizations
for
proposed
Baylands
development
would
discharge
to
an
improved
Visitacion
Creek.
As
described
in
Chapter
3,
Project
Description
,
of
the
Draft
EIR,
a
separate
stormwater
drainage
system
would
be
constructed
within
the
Baylands
to
collect
and
discharge
stormwater
runoff
from
Project
Site
development
to
meet
City
of
Brisbane
Storm
Drainage
Master
Plan
and
stormwater
treatment
requirements.
With
the
exception
of
the
Recology
site
that
currently
has
a
wastewater/stormwater
system
discharging
into
SFPUC’s
system,
stormwater
runoff
will
not
be
discharged
into
the
SFPUC’s
dual
wastewater/stormwater
system.
The
onsite
storm
drain
system
would
be
designed
to
meet
the
requirements
of
the
NPDES
permit,
as
stated
on
Draft
EIR
page
Project
Site
development’s
wastewater
flows
would
be
treated
by
an
onsite
recycled
water
plant
to
meet
onsite
irrigation
water
demand,
with
the
remaining
wastewater
collected
by
the
Bayshore
Sanitary
District
and
pumped
to
SFPUC
for
treatment
and
discharge
according
to
SFPUC’s
NPDES
discharge
permits.
The
onsite
recycled
water
plant
would
be
constructed
once
sufficient
wastewater
flows
were
being
generated
within
the
Baylands
to
provide
for
efficient
plant
operations.
Because
technologies
for
recycled
water
plant
design
continually
evolve,
a
specific
numerical
threshold
that
would
trigger
plant
construction
has
not
been
set.
A
specific
target
flow
that
would
trigger
the
required
construction
of
the
onsite
recycled
water
plant
will
be
determined
by
the
City
as
part
of
its
review
of
proposed
water
and
wastewater
plans.
This
target
flow
will
be
based
on
a
combination
of
the
amount
of
wastewater
generated
within
the
Baylands
and
the
demand
generated
by
Baylands
development
for
recycled
water.
The
combination
of
available
wastewater
for
recycling
and
demand
for
recycled
water
supply
will
be
evaluated
to
determine
the
level
of
Baylands
development
needed
to
provide
for
efficient
operation
of
the
recycled
water
plant.
The
Draft
EIR
acknowledges
that
as
much
as
75
percent
of
Project
Site
development
could
occur
prior
to
construction
of
the
recycled
water
plant.
As
opposed
to
impermeable
surfaces
that
block
infiltration
of
stormwater,
the
proposed
Water
Savings
Program
includes
the
use
of
hardscape
in
landscaping
design
that
would
allow
infiltration
of
stormwater
(e.g.,
porous
asphalt,
paving
blocks,
cobble,
decomposed
granite,
etc.).
The
word
“increase”
as
quoted
by
the
commenter
from
page
4.O-31,
was
used
as
a
comparison
to
non-permeable
surfaces
that
would
block
infiltration.
Comment
recommends
using
native
vegetation
instead
of
turf
to
reduce
water
demands.
As
described
on
Draft
EIR
pages
4.O-30
and
4.O-31,
water
demands
for
irrigation
of
turf
and
other
landscaping
would
be
served
by
the
recycled
water
plant
during
the
dry
Brisbane
Baylands
