This document is a design plan set for canal backfilling at the Barataria Preserve Unit of Jean Lafitte National Historical Park and Preserve in Jefferson Parish, Louisiana. The project, prepared by the National Park Service Denver Service Center, consists of 12 sheets detailing the backfilling of multiple canals to restore the wetland ecosystem and reduce environmental damage caused by historical canal construction.

The design plans include sheet overview, access plan, sequence of construction, and detailed technical specifications for eight parallel upper Kenta canal and various backfilling alternatives. Key construction phases include spoil bank degradation and vegetation removal, followed by plug and check meander installation. Backfilling methods vary by canal type and include partial backfill, complete backfill with gap designs, and embedded woody debris options. The project coordinates with existing utilities including Entergy Louisiana transmission lines, Enterprise Products operating pipeline, Shell pipeline, Enlink operating pipeline, and Gulf South operating pipeline. Construction sequencing accounts for three to four-foot canal depths and requires careful management of spoil bank material, environmental considerations for wildlife and marine mammals, and coordination with utility owners. Monitoring sites will be established adjacent to backfilled areas to assess restoration effectiveness. The design accommodates natural revegetation and specific plantings to establish forested bald cypress at designated locations.
