Written by GovTribe AI · Jul 16, 2025

These are engineering design plans for the Tiger Pass Bar Channel Maintenance Dredging project in Plaquemines Parish, Louisiana, prepared by the U.S. Army Corps of Engineers New Orleans District. The comprehensive set of technical drawings details the dredging work for approximately 2.25 million cubic yards of material to restore navigation in the Tiger Pass Ship Channel, with precise geospatial coordinates, channel centerline alignments, and profile views spanning multiple stations from approximately 237+48.63 to 772+15.

The plans include detailed technical specifications such as typical cross-sections, channel geometry, curve data, and disposal site configurations. The project involves single point discharge pipeline disposal of dredged materials into designated areas, with survey data collected in November 2023 and April 2024. The engineering drawings meticulously document channel elevations, bottom edges of cut, navigation markers, and geographical features around Chawee Bay and Joes Bay near the Gulf of Mexico, with the project area located in the vicinity of Venice, Louisiana.
