Extreme weather events, flooding and rising sea levels devastate communities, destroy or severely damage costly infrastructure, and introduce a strong element of uncertainty in current and future planning. This new normal spotlights how and where we build new -- or strengthen existing -- infrastructure and communities and the governance systems that manage and regulate these decisions and investments. Hear experts tackle these issues, from Hurricane Sandy to sea level rise in the Bay Area. What are the weak links in terms of existing infrastructure, cross-jurisdictional government response systems and disaster preparedness? Learn about state guidelines and legislation.

Poten2al
Consequences
— Flooding
of
bridges
or
of
tracks
will
interrupt
train
operations.
— Permanent
or
frequent
inundation
of
ballast
and
roadbed
will
damage
the
integrity
of
the
track
structure.
— Flooding
of
signal
cabinets
and
lights
can
cause
problems
for
the
signal
system
and
result
in
service
interruptions
and
delays
throughout
the
system.
— Flooding
of
roads
near
the
station
will
cause
problems
for
passengers
and
other
personnel
trying
to
access
the
station
and
boarding
platform.

Poten2al
Consequences
— We
don’t
know
them,
what
they
do,
what
they
want
— Risks,
vulnerability,
and
resiliency
differ
by
asset
— Do
we
want
to
team
up
with
our
neighbor?
— How
do
we
equitably
pay
for
the
adaptation?
— Is
one
adaptation
appropriate
across
asset
types?
— What
about
the
other
neighbors
around
that
should
participate
in
the
sense
of
fairness?

— Rail

— Neighbors

— Information

23. Governance
Collabora2on
— Consider

— Need

to
