Draft
EIR
Section
4.E,
Geology,
Soils,
and
Seismicity
,
includes
multiple
mitigation
measures
(4.E-2a,
4.E-2b,
4.E-3,
4.E-4b)
that
rely
upon
compliance
with
applicable
state
and
local
regulations,
namely
the
California
Building
Code,
as
well
as
the
final
design
parameters
and
building
recommendations
to
be
included
in
the
final
design-level
geotechnical
report
to
be
prepared
by
a
licensed
geotechnical
or
soil
engineer
and
subject
to
approval
by
the
City
Engineer.
For
example,
as
discussed
on
page
4.E-37:
The
geotechnical
report
required
by
Mitigation
Measure
4.E-2a
would
provide
site-specific
construction
methods
regarding
grading
activities,
fill
placement,
soil
corrosivity/expansion/
erosion
potential,
compaction,
foundation
construction,
drainage
control
(both
surface
and
subsurface),
and
avoidance
of
settlement,
liquefaction,
differential
settlement,
and
seismic
hazards.
The
report
would
also
include
stability
analyses
of
final
design
cut
and
fill
slopes,
including
recommendations
for
avoidance
of
slope
failure(s).
The
final
grading
plan
and
associated
development
elements
would
be
designed
and
constructed
in
accordance
with
requirements
of
the
final
design-level
geotechnical
investigation,
and
would
be
submitted
to
the
City
Engineer
prior
to
the
issuance
of
building
permits.
Designers
and
contractors
would
comply
with
recommendations
of
the
design-level
geotechnical
investigation
during
Project
construction.
Additionally,
a
licensed
geotechnical
or
soil
engineer
would
monitor
earthwork
and
construction
activities
to
ensure
that
site-specific
construction
methods
are
followed
during
Project
construction.
The
recommendations
would
be
incorporated
into
all
development
plans
submitted
for
site-specific
development
projects
within
the
Baylands.
As
demonstrated
for
Mitigation
Measure
4.E-2a,
each
of
the
aforementioned
mitigation
measures
includes
specific
performance
measures
based
on
site-specific
circumstances.
Also,
Subsection
4.E.3,
Regulatory
Setting
,
provides
a
thorough
discussion
of
federal,
state,
regional,
and
local
regulations.
Therefore,
the
EIR
demonstrates
that
the
application
of
existing
regulatory
standards
would
reduce
impacts
related
to
geology,
soils,
and
seismicity
to
less-than-significant
levels.
Similarly,
mitigation
measures
(4.G-2a,
4.G-2b,
4.G-2c,
4.G-2d,
4.G-2e,
4.G-2f,
4.G-2g,
4.G-2h)
within
Section
4.G,
Hazards
and
Hazardous
Materials
,
include
performance-based
standards
pursuant
to
regulatory
requirements
providing
for
the
management
of
soil
or
groundwater
within
the
Baylands.
As
discussed
in
more
detail
in
the
subsection
on
Responsible
Agencies
below,
the
Department
of
Toxic
Substances
Control
(DTSC),
San
Francisco
Bay
Regional
Water
Quality
Control
Board
(RWQCB),
and
San
Mateo
County
have
regulatory
oversight
for
remediation
of
contamination
resulting
from
previous
uses
on
the
site
and
for
Title
27
closure
of
the
landfill.
While
the
specific
remediation
technologies
that
will
be
employed
have
not
yet
been
determined,
the
Draft
EIR
includes
a
description
of
the
required
remedial
actions
that
would
be
completed
prior
to
any
Baylands
development
in
Section
4.
G
,
Hazards
and
Hazardous
Materials
,
on
pages
4.G-78
and
4.G-79.
Proposed
remedial
action
objectives
and
the
specific
remedial
action
plans
are
described
on
pages
4.G-81
through
4.G-86.
In
addition,
proposed
Project
Site
development
would
also
be
subject
to
land
use
controls
such
as
deed
restrictions
that
limit
site
uses
and
require
notifications
for
any
ground
disturbances.
All
of
these
measures
would
be
required
by
Title
27
CCR
Section
21190,
in
order
to
achieve
landfill
closure
and
to
minimize
or
eliminate
risk
to
human
health
and
the
environment
under
any
of
the
proposed
Project
scenarios.
These
actions,
as
they
pertain
to
the
former
landfill,
have
been
generally
described
in
the
Final
Brisbane
Baylands
Final
EIR
