result,
they
generally
do
not
result
in
standing
water
very
long
after
a
storm
event
and
can
remain
completely
dry
through
extended
summer
months
of
little
to
no
precipitation.
For
this
reason,
bioswales
and
culverts
would
not
represent
substantial
new
habitat
for
mosquitoes.
The
San
Mateo
County
Mosquito
and
Vector
Control
District
manages
San
Mateo
County’s
mosquito
control
program,
which
uses
multiple
methods
to
control
the
risk
of
disease
in
San
Mateo
County,
including
surveillance,
prevention,
and
control
of
mosquito
populations.
Proposed
Project
site
development
would
be
consistent
with
the
County’s
mosquito
control
program.
The
engineering
design
of
all
proposed
culverts
and
swales
will
be
reviewed
by
the
City
to
ensure
that
the
design
of
culverts
and
swales
minimizes
the
potential
for
standing
water
and
areas
for
mosquito
breeding.

Mitigation
Measures
4.H-4a
through
4.H-4c
address
Baylands
Project
Site
drainage
patterns
and
runoff
by
requiring
drainage
improvements
to
accommodate
all
increased
runoff
and
correct
existing
drainage
deficiencies.
Rather
than
relying
on
natural
processes
to
filter
sewage,
Mitigation
Measure
4.H-4a
requires
that
drainage
inlets
fronting
the
Levinson
Overflow
Area
be
isolated
from
the
Brick
Arch
sewer
system.
Doing
so
protects
public
health
and
safety,
and
is
not
intended
to
characterize
the
functionality
of
the
Levinson
Marsh.
In
addition,
Mitigation
Measures
4.C-2a,
through
4.H-2c
provide
additional
requirements
to
protect
wetlands
ensuring
that
maintenance
of
the
total
area
and
or
overall
functions
and
values
of
jurisdictional
wetlands
or
waters
of
the
U.S.
would
apply
to
site
development.
In
compliance
with
CEQA,
the
above-referenced
mitigation
measures
include
performance
standards
to
ensure
that
the
significant
effects
of
Project
Site
development
are
mitigated
to
less
than
significant
levels.
Final
design
plans
would
not
be
tied
to
the
referenced
BKF
modeling
that
was
completed
as
part
of
the
2011
Infrastructure
Plan
prepared
as
part
of
proposed
Brisbane

the

rather
to
the
requirements

Mitigation
Measure

4.H-24
of
the
Draft
EIR,
which
would
require
adherence
to
a
final
Stormwater
Management
Plan
that
is
consistent
with
the
most
recent
NPDES
C.3
requirements.
The
