The PMSC mission is to leverage local expertise and additional technical resources into a regional collaboration that will promote:
• broader understanding of storm surge dynamics in the lakes,
• better-informed storm surge risk-reduction strategies for all communities around the Lakes, and
• the environmental sustainability, community resilience, and safety of residents through enhanced storm surge risk management.
An initiative from the Coastal Sustainability Program at the Lake Pontchartrain Basin Foundation.
This website will serve as a repository for documents and data files for the project:
Workshop #13 is scheduled for Friday, May 12 in Denham Springs. It will cover the 2016 riverine flooding within the Pontchartrain Basin.
Email email@example.com if you would like to be added to the invitation list.
A few useful maps are below:
The map below depicts the extreme storm surge risk. It is based on SLOSH model run the NHC, and shows the maximum possible surge flooding, based on a suite of category 5 storms. “MOM – Maximum of Maximums”. It is a snapshot in time that reflects the landscape & climatology at the time of the analysis along with the basic assumptions of the model. For reference, it also shows the approximate storm surge outline for Hurricane Isaac, a weak but slow moving category 1 storm.
This shows the elevation and bathymetry for the Pontchartrain-Maurepas study area. It is based off a dataset produced by NOAA, and it also shows levees using a CPRA dataset. A higher resolution version along with our storm surge dynamics report is available here.
Here is the early draft of our projects inventory map with the 2010 USGS Land Change map as the basemap. This project is ongoing and we hope to release it in early 2017.
Here is a map showing the four major coastal lines of defense that influence storm surges in Lake Pontchartrain and and Lake Maurepas. Storm surge risk for the communities along Lakes Pontchartrain and Maurepas is function of the conditions of these major landscape features.
