About this file

Written by GovTribe AI · Jul 15, 2025

These are detailed engineering design plans for the Calcasieu River and Pass Dredge Material Management Plan (DMMP) project, prepared by the U.S. Army Corps of Engineers New Orleans District. The plans cover the CDF-H (Confined Disposal Facility H) degrading and dike construction in Cameron Parish, Louisiana. Key technical details include site-specific cross-sections, soil boring data, geotechnical test results, and construction specifications for site preparation, including dewatering the site to elevation 15' NAVD88, excavating the platform, and constructing earthen retention dikes with geotextile reinforcement. The project involves a 140-foot landward shift of the existing dike centerline, site grading, and preparing the area for future dredge material disposal, with comprehensive geological and engineering data supporting the design approach.
