HSDRRS levee lift Draft General Re-evaluation Reports public meetings scheduled

Published Jan. 16, 2020

NEW ORLEANS – The U.S. Army Corps of Engineers has scheduled two public meetings regarding the release the of Draft General Re-evaluation Reports for the Lake Pontchartrain and Vicinity (LPV) and West Bank and Vicinity (WBV), which comprise the post-Katrina risk reduction system.



Jan. 21, 2020 6 p.m.

6400 Belgrade Street

Algiers, LA 70131


Jan. 22, 2020 5 p.m.

6500 Spanish Ft. Blvd

New Orleans, LA 70124


The purpose of the two General Re-Evaluation Reports is to evaluate whether federal participation to carry out measures that address consolidation, settlement, subsidence, sea level rise, and new datum that would sustain the Hurricane and Storm Damage and Risk Reduction System are economically justified, technically feasible and environmentally acceptable.


Each report has a Tentatively Selected Plan (TSP) of system-wide periodic levee lifts, floodwall modification, and floodwall replacement to the projected 100-year level of risk reduction through the year 2073. Construction of the TSPs would generally occur in the same footprint as the existing levees and structures.


Through each TSP, existing levees would be lifted as-needed before the combined effects of consolidation, settlement, subsidence and sea level rise reduce the levee elevations below the required design elevation. In some reaches, levee lifts may need to occur more than once through the period of analysis in the future. Floodwalls that will need to be higher in the future to address those same effects will either be modified or replaced.


The general public, interested parties, and stakeholders are invited to comment on the TSPs. The draft reports contain descriptions of the projects, evaluation of the alternatives under consideration, and analysis of potential environmental impacts. All public comments received will be addressed and considered accordingly as part of the continued development of the TSPs into more detailed Recommended Plans.
