NAME OF APPLICANT:  Terrebonne Port Commission, c/o GIS Engineering, LLC, Attn: Mohan Menon, 450 Laurel Street, Suite 50, Baton Rouge, Louisiana 70801 

LOCATION OF WORK:  In the Houma Navigation Canal (HNC) and the Gulf of Mexico, approximately 24 miles south of Chauvin, Section 9, T22S-R18E, in Terrebonne Parish, within the Terrebonne Basin in hydrologic unit (HUC 08090302), as shown on the attached drawings.   

CHARACTER OF WORK:  The applicant has requested Department of the Army authorization to dredge the HNC using a barge mounted cutter head dredge in effort to maintain the authorized channel depth.  The applicant has separated the project into two segments with the first taking place from mile 11 to mile 0 and the second segment from mile 0 to mile -3.5.  The first segment of channel is 150’ wide, 15’ deep, and will be dredged down to 18’.  The second segment is 300’ wide, 18’ deep, and will be dredged down to 22’.  The dredge area will cover approximately 375 acres and the material will be deposited in two different sections of open water covering 890 acres.  The material will be deposited into two shoal locations adjacent to the navigational channel and into open waters 1000' west of the navigational channel.  Approximately 6,500,000 cubic yards of material will be dredged and re-deposited.  

A Preliminary analysis has determined that the proposed project would directly impact approximately 1,265 acres of jurisdictional water bottoms.   

The applicant stated that they have designed the project to avoid and minimize direct and secondary adverse impacts to the maximum extent practicable.  Any further reduction would limit usage of the canal and, therefore deem the project impracticable.  There are not wetland impacts associated with this project.
