2023 Coastal Master Plan


The 2023 Coastal Master Plan will build upon previous master plan efforts and strive to ensure that the collective effects of project investments reduce storm surge-based flood risk to communities, provide habitats to support an array of commercial and recreational activities, and support infrastructure critical to the working coast. This will be achieved by harnessing natural processes, focusing protection on key assets, and adapting to changing coastal conditions.


Join CPRA as we partner with Restore the Mississippi River Delta and several local partners, for a series of community conversations ahead of the 2023 Coastal Master Plan’s official release in early January 2023.

The meetings will be an opportunity for communities across the coast to engage directly with the Coastal Master Plan team and complimentary dinner will be served.
