The ability to not only bounce back, but “bounce
forward” – to recover and at the same time to
enhance the capacities of the community to
better withstand future stresses.
Due to climate change and sea level rise, assets
with multi-decadal lifespans will be exposed to
weather events more extreme and less easy to
predict than ever before. Building codes and
zoning need to plan for changes.
Not just the built environment, but resilience on
the societal level also.
The ability to not only bounce back, but “bounce

destroy natural areas.
• Accommodate – “Buy Some Time” Retrofit or raise buildings,
elevate roads, enhance wetlands.

decision to withdraw, relocate or abandon assets includes
setbacks and restore wetlands.

as communications aspects of sustainability, in addition to mitigation
and adaptation to coastal hazards.

A Resilience Zone is a special improvement district,
precinct, neighborhood, or corridor designated in
official planning documents for comprehensive risk
management and upgrading so that it performs
with resilience in the face of a variety of predictable
and unpredictable extremes.
‘Resilience’ is itself proposed here as a new
category of urban property performance. Resilience
is the ability of a property and its surrounding
urban area to provide predictable, targeted benefits
to tenants, residents and users, and predictable
returns to owners and investors, under a wider
range of often unpredictable circumstances.
