St. Bernard Parish Government recently broke ground on the Lake Lery Marsh Creation (Phase 2) project near Delacroix. The project ($11 million) was designed under the Coastal Impact Assistance Program and Phase 1 (68 acres of marsh creation) was completed in 2016.

The parish has since secured Phase 2 construction funding via the RESTORE Act Direct Component Program ($300,000) and the Coastal Protection and Restoration Authority RESTORE Act Parish Matching Program ($2.7 million). Phase 2 will include at least 28 acres of additional marsh creation or nourishment.

As the below map indicates, the project involves dredging sediment from a borrow area in Lake Lery and delivering the sediment via a dredge pipe (orange line) into the target marsh creation cell near Delacroix.

What Should I Expect?

  • Construction crews will be active in the area from September 2021 through December 2021.
  • The project may create some navigation challenges and temporarily impact area water quality.

What is Being Done to Limit Adverse Impacts?

  • The contractor will conduct all operations in accordance with the permits, rules and regulations of the U.S. Army Corps of Engineers and the U.S. Coast Guard.
  • The contractor will install temporary navigational aids (warning signs, buoys, and lights) where necessary and appropriate.
  • The contractor may strategically place hay bales and turbidity curtains to limit impacts to water quality.
  • The contractor will avoid impacts to fish, wildlife, and commercial and recreational fishing activities to the extent possible.
  • The contractor will safely demobilize in advance of any tropical weather event.
