Community Resiliency, Morganza to the Gulf and by gty33410


									Community Resiliency,
 Morganza to the Gulf
         Community Resiliency
• Resiliency is frequently defined as the capacity
  of human and natural/physical systems to
  adapt to and recover from change.

• This change can be the result of an ongoing
  event occurring over a long period of time
  (land loss) or the result of a single specific
  event (such as a hurricane).

  Hurricane Protection
The residents of south
Louisiana need storm

Terrebonne Parish is
experiencing the highest rate
of land loss in coastal
Louisiana, and communities
in the lower parish are often
flooded from extreme high
tides and small storms.

Wetland restoration alone
cannot do the job; storm
surge barriers are also
  Hurricane Protection

  Consider the entire

Hurricane protection systems
must be built and maintained
so that the ecosystem remains
dynamic and functional.

We must also ensure that
protection and restoration
actions do not induce flooding
in low-lying communities.
  How Communities Can
  Minimize Their Flooding

Use smart growth; prohibit
development in wetland
areas and require buffer
zones near levees.

Communities should strictly
enforce National Flood
Insurance Program
regulations and use
appropriate building

Smart growth.

Wetland areas inside the
hurricane protection
system need to remain
intact and undeveloped.

Smart growth.

Once a national and state
commitment to building a
levee is made, local
governments must enforce
appropriate land use and
zoning regulations to
ensure that the system,
once built, contributes to
the long-term
sustainability of the region.

Flood insurance.

According to FEMA, a home has
a 26% chance of being damaged
by a flood during the course of a
30 year mortgage, compared to a
9% chance of damage from fire.

Given the base risk, all residents
of coastal Louisiana should
purchase flood insurance, even if
they live inside a hurricane
protection system.

Elevating & retrofitting

Hazard mitigation funds can be
used to elevate, retrofit, or buy
out homes that have suffered
damage from flooding.

Adoption of these kinds of
measures has the added benefit
of lowering flood insurance
premiums for homeowners as
well as reducing storm

Building codes.

In 2007 the state enacted the
Louisiana State Uniform Construction

This new building code adopted
provisions from national and
international codes and was
designed to ensure that new
construction could better withstand
hurricane winds.

When used in concert with structural
elevation, the code will result in
substantially safer buildings.

FEMA-approved hazard
mitigation plans.

All 64 Louisiana parishes plus an
additional 14 communities received
funds from FEMA to develop hazard
mitigation plans.

Hurricanes and storms were the
main hazards addressed in the
plans, which made
recommendations for retrofitting
critical facilities to make them more
disaster resistant.

  Minimize Their
  Flooding Risk

Evacuation routes.

We need to make sure that
evacuation routes are raised where
necessary and adequately armored
so that residents may safely
evacuate and return after a storm

DOTD is working with the
Louisiana State Police and the
Governor’s Office of Homeland
Security and Emergency
Preparedness to continually
improve emergency plans for
hurricane evacuation.
• Restoration and non-structural measures can
  reduce the risk from storm surge.
• But in most areas, the risk of storm surge
  flooding will remain unacceptably high, even
  after restoration and non-structural measures
  are factored in.
• To more fully protect these high risk areas,
  hurricane protection structures are
  recommended in order to provide more
• Structural protection, such as Morganza to the
  Gulf , doesn’t just reduce risk associated with
  the design event, it reduces risk associated
  with more frequently occurring lesser events
  that would otherwise regularly disrupt
  regional production and economy.
