Louisiana Flood Risk and Resilience Viewer

Louisiana's Coastal Protection and Restoration Authority (CPRA) has launched a “Flood Risk and Resilience Viewer,” an online resource which displays information on coastal land change, flood risk, and impacts to communities. This innovative tool provides coastal residents with access to the state’s best information about how Louisiana’s coast may change in the future, as well as resources to make communities and properties safer.

Leverage the state's best information on how the Louisiana coast may change to advance hazard mitigation and coastal planning. 

The tool integrates the results of CPRA's 2012 Coastal Master Plan along with coast-wide data including infrastructure, social vulnerability, and other elements of the built environment - showing land loss and flood risk across the coast for current day as well as 50 years into the future. This information can be used by LA state agencies, coastal stakeholders, and community advocates in coastal planning and hazard mitigation efforts. In addition, a variety of resources are provided to enable homeowners and business owners to take steps towards reducing their flood risk.

The Viewer provides multiple data layers and views to choose from:

  • 2012 Coastal Plan: to learn more about project details for specific community areas.
  • Land Change: Explore what the landscape will look like over the next 50 years - choosing an Environmental Scenario and Time Period to display land change for those conditions.
  • Flood Risk: Explore current and potential future flood depths over the next 50 years by selecting Environmental Scenario, Flood Event, and Time Period to display flood depths for those conditions.
  • Impact on Communities: Explore impacts on community facilities by selecting an Environmental Scenario, Flood Event, and Time Period. Facilities located in areas impacted by flooding under selected conditions will be highlighted.
  • Socio-Economics: Explore the socio-economic context of coastal Louisiana by selecting an option to see different social, economic, and demographic variables that may make communities more vulnerable to flood risk. Data is based on the 2007-2011 American Community Survey (ACS).

Recognizing that communities are vulnerable to flood risk for a variety of reasons beyond just their physical location, this tool allows users to review economic and social factors that influence risk. The socioeconomic filters include per capita income, housing density, the rural population, the elderly population, the non-English speaking population, and the population without a high school diploma.

The The Coastal Protection and Restoration Authority is established as the single state entity with authority to articulate a clear statement of priorities and to focus development and implementation efforts to achieve comprehensive coastal protection for Louisiana. CPRA’s mandate is to develop, implement, and enforce a comprehensive coastal protection and restoration Master Plan.
