The design of this project includes two separate borrow areas located within the Houma Navigation Canal (HNC), from which suitable material was hydraulically pumped to a large, fully contained, fill area approximately 4 miles away. The fill area for the project was designed in an area which is protected from wave erosion by an existing natural ridge. This will help the TLCD achieve the required design life of 20 years. DCC incorporated local studies or optimal wetland plant habitats and relative sea level rise, along with geotechnical considerations of sub-soil and marsh-fill consolidation and compaction to determine the optimal target marsh elevation for the project.
