2017 Coastal Master Plan

The CPRA continually works to improve its methods to ensure projects are completed as efficiently and effectively as possible. Louisiana citizens will see this progress reflected in the 2017 Coastal Master Plan update. Materials currently being developed for the 2017 effort will be cataloged on this page for ease of reference.

Coastwide Reference Monitoring System (CRMS)

CRMS is a multiple reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling. This approach includes a suite of sites that encompass the range of ecological conditions for each stratum, with projects placed on a continuum of conditions found for that stratum.

Flood Risk and Resilience Viewer

This resource displays information on coastal land change, flood risk, and impacts to communities. This innovative online-tool provides 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.

Journal of Coastal Research: Special Issue #67

The extensive scientific analysis that was conducted to support the decision-making process for the 2012 Coastal Master Plan was an unprecedented effort.   The advances in science-based planning made in the Coastal Master Plan incorporate the principles and practices recommended by the science and engineering community, which included over 100 practitioners with regional, national and international experience.  The Journal of Coastal Research (JCR) Special Issue #67 highlights this work.

This special issue contains 10 peer-review articles about key aspects of the Master Plan analysis, including eco-hydrology, wetland morphology, vegetation, fish and wildlife habitats, nitrogen removal, surge and waves, flood risk, parametric uncertainty and planning tool.  The special issue also includes an overview of the science-based and publicly-informed decision making process.  Over 40 scientists, engineers and planners contributed as authors to the special issue.

Monitoring Data

Hydrographic, accretion, herbaceous marsh vegetation, soil properties, and surface elevation data collected by the CPRA are now available on-line. All downloaded files will be in zipped, comma-delimited format with headers that describe the data. For a detailed explanation of all data types, please review the Data Descriptions document.
