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.

2 of the worlds largest ports and 6 of the top 10 largest ports in the U.S. onthe Gulf Coast.

50% of all U.S. international trade tonnage passed through Gulf coastports in 2009

Ecosystem

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

What the Master Plan Delivers

The plan includes a wide variety of project types distributed throughout the coast.We are using every tool in the toolbox to protect and restore south Louisiana.

Nonstructural physical measures: Elevation of structures (i.e. homes, businesses) Floodproofing of structures (localized levees, flood resistance membranes,

watertight closures, etc.)

Voluntary acquisitions or buyouts

Community relocation measures

Nonstructural programmatic measures: Hazard mitigation and recovery planning

Public education and outreach

Ordinances and building codes Policy and regulation changes

Land use planning & floodplain management

41/67

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.

Program Framework

45


46/67


47/67


48/67

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

3) Provide Options: Maximize choices of flood risk reductionmeasures and clearly communicate options to individuals andcommunities so they can make decisions for themselves.

48


49/67

Develop CPRA Subcommittee and Advisory Group to enhance

coordination of agencies/efforts

Include members from:

Coastal Parish Officials Federal & State Agencies Community Leaders Non-Profits Academia, Researchers Levee Boards Economic Development Organizations

Planners, Floodplain Managers, Architects, Engineers

4) Create Platforms for Collaboration & Action: Buildnetworks of coastal stakeholders and community participantsto partner in program development and implement solutions.

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

CPRA Coastal Community ResiliencySubcommittee

53/67

Major focus areas moving forward: Outreach & Education

Gathering lessons learned from others

Establishing a network of knowledgeable partners in the field

Next Meeting: May Timeframe

Will focus on the following items: Review updated data and feedback from stakeholders

Develop a targeted outreach and engagement plan

Discuss appropriate design criteria and framework for streamlinedand consistent implementation of projects across the coast

Other stakeholders will be engaged as certain key topics are addressed: Community outreach Design/architecture Land use planning Structural protection Economic development Relocation

Goal: toprovide an innovative, collaborative framework to support solutionsthat reduce the socio-economic, cultural, and environmental risks thatcommunities face from coastal hazards.

30 core participants from federal, state, parish, institutes, and academicswho currently work on resiliency issues or research.

Group will provide feedback on lessons learned, implementation issues,communications, and the programmatic framework.

Stakeholder Survey Results

56/67

Conducted a Stakeholder Questionnaire to collect feedback on thefollowing: How can we best frame the nonstructural program?

What nonstructural-related work is currently being done?

What challenges do practitioners face in their work?

What policies/programs are needed to support effective implementation?

What groups are interested in collaborating with CPRA on the AdvisoryBoard?

Outline program strategy for project prioritization,implementation and community outreach

Next Steps

64


65/67

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.
