"This online data viewer provides user-friendly access to coastal land cover and land cover change information developed through NOAA’s Coastal Change Analysis Program (C-CAP). The tool summarizes general change trends (such as forest losses or new development) and provides tables, maps, and reports to enhance communication and decision-making."

"This online tool provides managers and citizens with easy-to-understand charts and graphs that describe complex coastal data. Users select a county of interest and the website does the rest, creating a helpful educational tool for governing bodies and citizen groups. Current snapshot topics include flood exposure, wetland benefits, and ocean and Great Lakes jobs."

Coastal Flood Exposure Mapper

"With its high incidence of storms and hurricanes and valuable ecological and economic resources, the Gulf region is a high-risk area with great potential to demonstrate natural risk reduction solutions. The Coastal Resilience approach and tools have been applied Gulf-wide and at specific sites, including those that help identify where to implement oyster reef restoration to meet social and ecological goals."

More information about this tool is available as a PDF or video. Information about this tool's use for specifically studying flood and sea level rise is available here.

Louisiana Coastal Master Plan (2017)

Source: Coastal Protection and Restoration Authority

"The 2017 Coastal Master Plan sets an ambitious path to respond to the loss of our coastal land and the threats from storm surge events. The master a list of projects that build or maintain land and reduce risk to our communities. Because the funding for all of those projects is not available now, the master plan identifies a long-term program of construction, operations and maintenance, and adaptive management that is guided by a robust and continuous planning process, to be implemented as funds become available..."

"Social vulnerability refers to the resilience of communities when confronted by external stresses on human health, stresses such as natural or human-caused disasters, or disease outbreaks. CDC's Social Vulnerability Index uses 15 U.S. census variables at tract level to help local officials identify communities that may need support in preparing for hazards; or recovering from disaster."
