Louisiana’s Strategic Adaptations for Future Environments

Louisiana’s Strategic Adaptations for Future Environment (LA SAFE) supplements Louisiana’s 2012 Coastal Master Plan by serving as a generalized framework for land use and community development along Louisiana’s coast. Recognizing that not all vulnerable areas can be protected from flood risks, the report outlines three different development strategies - Retreat, Retrofit, or Resettle.  Based upon the expected flood inundation from a 100-year storm event over the next 50 years, the strategies respond to three typological zones: Retreat from areas projected to experience more than 14 feet of flood inundation; Retrofit places of economic and cultural value projected to experience between 3 and 14 feet of flood inundation; and Resettle to maximize underdeveloped areas and high-ground corridors that are projected to experience less than 3 feet of flood inundation.

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.

Resettlement as a Resilience Strategy

October 27, 2015

This document provides background information and guidance to Louisiana’s state and local governments on the retreat and resettlement process, and outlines the strategy for the ongoing resettlement of the Isle de Jean Charles Biloxi-Chitimacha-Choctaw Native American community. As sea level rise and land loss threaten Louisiana’s low-lying regions, coastal communities must consider the costs and benefits of retreat and resettlement. The report provides a history of resettlement in the United States and makes the case that the resettlement of Isle de Jean Charles is just the beginning of more resettlement projects in the region.

Louisiana: Addressing Sea-Level Rise

August 19, 2015

This case study, developed by the Georgetown Climate Center, examines state and local activities in Louisiana to reduce coastal vulnerability from sea level rise, extreme storms, and land subsidence.  It focuses on how the state is prioritizing and designing coastal flood protection and restoration projects in consideration of future sea-level rise through the Louisiana Coastal Master Plan.

New Orleans Comprehensive Zoning Ordinance, Article 23: Landscape, Stormwater Management, and Screening

May 2015

In 2015, the New Orleans City Council adopted a new Comprehensive Zoning Ordinance (CZO). Article 23 of the CZO addresses landscaping and stormwater management with the intended purpose of reducing the urban heat island effect, decreasing flooding and strains on the existing drainage system, improving water conservation, and protecting public health, safety, and welfare. Article 23 of the CZO does not directly mention climate change or climate adaptation, but does specify regulations that can improve the cities ability to manage stormwater in the face of increased precipitation and mitigate heat in the face of rising temperatures though green infrastructure.

Louisiana Coastal Adaptation Toolkit

2015

The Louisiana Coastal Adaptation Toolkit provides adaptation resources that communities can use to address climate impacts on coastal Louisiana. This toolkit highlights adaptation strategies, and offers guidance on how to use certain practices or policy strategies in concert with the natural environment of Louisiana’s coast to foster adaptation. In addition, the toolkit contains links to resources on each of the coastal impacts covered in this document, and funding options to implement these adaptation strategies.

Encroaching Tides: How Sea Level Rise and Tidal Flooding Threaten U.S. East and Gulf Coast Communities over the Next 30 Years

October 2014

This report from the Union of Concerned Scientists describes the threat of tidal flooding in the East Coast and Gulf regions and offers steps that communities can take to adapt. The report makes the case that tidal flooding, currently just considered a nuisance, could become a daily or weekly occurrence, redefining how and where people along the coast “live, work, play, and move through their daily lives. " Data was collected in 52 locations to provide projections for sea level rise and tidal flooding in the region until 2045.
