3. 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.

12. • Protect/Fortify – “Stand and Defend” Sea walls, dikes, groynes.
But may increase future risks, create false sense of security,
destroy natural areas.
• Accommodate – “Buy Some Time” Retrofit or raise buildings,
elevate roads, enhance wetlands.
• Managed Retreat/Relocation – “Get Out of the Way” Strategic
decision to withdraw, relocate or abandon assets includes
setbacks and restore wetlands.
• Avoid – “Stay Out of the Way” No further development in high
hazard areas.

27. 8) Formal Scenario Planning
a) Engage Stakeholders in Planning Process
I. Hold Public Meetings/Charettes to inform residents of long‐term issues and to
develop a wide support base
9) Hire a qualified sustainability officer with experience in technical as well
as communications aspects of sustainability, in addition to mitigation
and adaptation to coastal hazards.
10) The city to research and apply for grants to fund the above analysis and
possible pilot projects.
11) Plan Resilience or Value Zones. (Managed Relocation)
12) Ensure that our beach re‐nourishment programs are protected for the
next 50 years (ACE now says the county has 50 years of sand offshore);
(Fortify)
10) Review every dune in town every year and budget for select re‐
nourishment and re‐vegetation where appropriate. (Fortify)

29. 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.
