page
4.H-30
of
the
Draft
EIR
recognizes
that
while
much
of
the
Baylands
Project
Site
is
located
outside
of
the
100-year
flood
zone,
there
are
some
low-lying
areas
that
could
be
subject
to
flooding
if
left
at
current
ground
elevations.
However,
as
required
by
Mitigation
Measure
4.H-4a
on
page
4.H-30,
“Drainage
improvements
shall
accommodate
the
100-year
peak
storm
event
within
the
piping
system
and
streets
such
that
building
finished
floor
elevations
provide
a
minimum
of
1-foot
of
freeboard
above
the
100-year
storm
event
hydraulic
grade
line
water
elevation
with
tidal
flow
and
100
years
of
estimated
sea
level
rise.”
In
addition,
the
City’s
standard
conditions
of
approval
for
site-specific
development
requires
that
site
grading
and
drainage
be
designed
to
as
to
avoid
standing
water,
expect
in
basins
specifically
designed
for
that
purpose.
By
ensuring
that
finished
floor
elevations
of
all
proposed
development
are
a
minimum
of
one
foot
above
the
100-year
flood
zone
with
tidal
flow
and
100
years
of
estimated
sea
level
rise,
and
positive
drainage
is
provided,
flooding
impacts
would
be
reduced
to
less
than
significant
levels.
As
stated
in
the
Draft
EIR
on
page
4.H-5,
the
FEMA
flood
maps
that
were
updated
in
October
2012
were
used
as
a
source
for
the
flood
analysis
in
the
Draft
EIR.
The
sources
listed
for
Figure
4.H-3
are
modified
as
follows:
Source:
ESA,
2012
and
FEMA,
1983
2012
Although
BCDC
does
not
provide
flood
mapping,
it
does
maintain
standards
for
flood
protection.
As
stated
on
page
4.H-15,
BCDC
has
jurisdiction
within
the
Baylands
Project
Site
that
“includes
the
Brisbane
Lagoon,
Visitacion
Creek,
and
a
100-foot
shoreline
band
around
these
features,
each
of
which
are
designated
Waterfront
Park,
Beach”
in
the
proposed
development
at
the
Baylands.
The
proposed
developments
would
be
required
to
adhere
to
the
San
Francisco
Bay
Plan
policies
where
applicable.
Sea
level
rise
is
a
global
phenomenon
that
will
affect
all
coastal
areas
within
the
geographic
area
analyzed
for
cumulative
impacts
in
the
Draft
EIR.
Implementation
of
the
mitigation
measures
developed
for
the
proposed
developments
at
the
Baylands,
specifically
Mitigation
Measure
4.H-8,
would
reduce
impacts
from
sea
level
rise
and
flooding
to
a
less
than
significant
level
through
incorporation
of
the
Sea
Level
Rise
Risk
Assessment
and
any
subsequent
requirements
that
result
from
it.
The
Draft
EIR
text
cited
in
this
comment
provides
a
“regulatory
setting”
to
identify
relevant
General
Plan
requirements
with
which
proposed
Baylands
development
must
comply.
The
comment
incorrectly
concludes
that
the
Draft
EIR
relies
solely
on
General
Plan
policies
to
address
water
quality
issues.
