Over the last 100 years hurricaneshave caused approximately
$2,700 billion(in 2010 dollars) across Texas,Louisiana, Mississippi, and
Alabama.

As storms intensify andincrease in frequency andcoastal environmentscontinue to degrade, the Gulf
Coast could face cumulativeeconomic damages ofaround
$350 billion
over the next twenty years.

97% of commercial seafood landings from the Gulf rely onestuaries and wetlands
75% of North American migratory birds depend on estuarinehabitats during migration
1 acre of wetlands can sequester significant amounts ofcarbon dioxide and store 1.5 million gallons of water therebyreducing flooding impacts

watertight closures, etc.)
Voluntary acquisitions or buyouts
Community relocation measures
Nonstructural programmatic measures: Hazard mitigation and recovery planning
Public education and outreach

1. Increase coordination among state and parishagencies working on nonstructural issues inLouisiana. Need a single entity to act as aclearinghouse.
2. Consider amending regulatory requirements,
such as: 1) local land use planning; 2) buildingcodes; 3) flood damage preventionordinances; 4) risk reduction project funding.
3. Identify the needs of Louisiana residents andencourage the development of funding and
support initiatives to meet those needs.
4. Train officials and educate the public on theirflood risks and the nonstructural optionsavailable to them.

1) Develop Data & Tools: Develop integrated databases on flood risk,vulnerability, and socio-economic trends to determine the most effectiveresilience measures.
2) Provide Information: Increase public awareness of current and futureflood risks due to climate change and provide clear mapping and
visualization tools for coastal communities.
3) Provide Options: Maximize choices of flood risk reduction measuresand clearly communicate options to individuals and communities so theycan make decisions for themselves.
4) Create Platforms for Collaboration & Action: Create networks ofcoastal stakeholders and diverse community participants to partner inprogram development and implement solutions.

Outline the specific operational structural of the program and seek
approval from CPRA
Determine appropriate methods for prioritizing projects in areas ofhigh risk which best maximize the MP risk reduction objective
Provide communities and parishes with effective options for the useand dispersal of funds

Goal: to provide an innovative, inter-agency partnership whichsupports a more holistic statewide decision making process to reducethe socio-economic, cultural, and environmental risks that communitiesface from coastal hazards.
Charge: Synchronize, streamline, and further develop agency efforts to enhance
coordinated decision making
Focus resources on critical areas of need
Provide clear recommendations on policies and procedures for
nonstructural implementation
Anticipate meetings held quarterly with reports back to the CPRABoard as we progress

Current Act ions: Develop a GIS database of projects implemented since Hurricanes Katrina
and Rita, high risk areas, and census/demographic data (e.g., income,education, age, race, etc.).
Conduct a higher resolution spatial analysis with the CLARA model than thatprovided in the 2012 Coastal Master Plan.
Use benefit-cost and vulnerability analysis to assist in the identification of highpriority areas.
Consider additional nonstructural options, such as additional levels offreeboard and different acquisition heights.
CPRA will utilize the updated data to provide enhanced visual and graphic toolsthat can help to educate and inform the public on their levels of risk andresiliency options.
