Thibodaux-Lockport-Bayou Blue Gheens Valentine-East Lockport-Larose
The boundary is the area enclosed by a polygon beginning at the intersection of Bayou Lafourche and LA Highway 20 (North Canal Blvd.) in Thibodaux. The Boundary then follows LA Highway 20 north and east to the intersection of LA Highway 20 and the Choctaw Road. The boundary then follows the Choctaw Road generally to the south east to the intersection of the Choctaw Road and the Laurel Valley Road. From there the boundary follows the Laurel Valley Road generally south to the intersection of Laurel Valley Road and LA Highway 308 extending across LA Highway 308 to Bayou Lafourche. From there the boundary meanders up the east bank of Bayou Lafourche to the point of beginning at the intersection of North Canal Blvd. in Thibodaux. The 2010 Census shows a population of 4,002 in this Project Area which represents a 67% increase in population over the last 20 years with a 23% increase in the last 10 years.
Legendre – St James – 80 Arpent canals: The NLLD is confident that improvements to the existing drainage can be made in the St James Plantation area. This drainage also impacts the drainage in portions of the City of Thibodaux which drains through this basin. Broadly defined, this project includes clearing the canals and adjacent rights of ways of debris and vegetation, along with maintenance dredging of the canals. Engineering and surveying to receive permits for all of these projects are currently in process or has been completed by the NLLD. Clearing and Maintenance Dredging of the Legendre Canal has recently been completed.
St. James Canal Clearing Project: This project includes clearing the St. James Canal and adjacent rights of ways of debris and vegetation, along with maintenance dredging of the canal. Engineering and surveying to receive permits for this project are currently in process by the NLLD through its engineer assigned to the project, Leonard Chauvin, Inc. The NLCLDD has cleared trees from this Canal post Hurricane Isaac.

80 Arpent Canal Clearing Project: This project includes clearing the 80 Arpent Canal and adjacent rights of ways of debris and vegetation, along with maintenance dredging of the canal. Engineering and surveying to receive permits for this project are currently in process by the NLLD. The NLCLDD has cleared trees from this Canal post Hurricane Isaac. This project is also continues into the Choupic Project Area (See project No. 6400.53Z). Recently, the NLLD received $1.1M in State Capital Outlay funds for this project.

Backwater Flood Protection Levees (Broad Scope): This broadly defined project would include making improvements to various existing backwater flood protection levees within the project area. Targeted areas include the Sugar Ridge Subdivision area, and the Chackbay and Choctaw communities on the south side of Highway 20, and the Choctaw Road to the Laurel Valley Road. This broadly scoped project is assigned the following COA and estimated funding is primarily for project development.

While no threats were reported during Hurricane Isaac in August of 2012 to the following system, record high water pushed by the storm into the upper portions of the Barataria Basin and high rainfall amounts give reason to consider improvements to the following systems. The following individual project is being added as a result of this newly demonstrated weakness to flood protection. Further Project Development is required in the following system.
Chackbay 101 / Water Tower Forced Drainage Area / Backwater Protection Levees: This 630 acre forced drainage system in the Chackbay Community protects 204 residences, several businesses, and other infrastructure. The system has approximately 17,856 feet of ring levees providing backwater flooding protection. Forced drainage of the area is accomplished with two pump stations. The Water Tower Pump station has 1 – 20” diesel fueled, engine or electric motor driven pump which discharges into the 101 reservoir canal. The Chackbay 101 Pump Station has 2 – 24” diesel fueled, engine driven pumps. Overall, the ring levees are insufficient in height and profile with multiple encroachments and many trees and roots in the levees. Hurricane Isaac did not top the levee system; but, it was threatened in several locations. Proposed improvements would include re-capping and re-shaping the entire ring levee, clearing and widening of internal drainage channels / culverts and making improvements at the existing WT Pump Station.

Thibodaux Drainage Canal Improvements. The City of Thibodaux has requested drainage canal maintenance dredging to improve existing drainage conditions in in the area east of North Canal Blvd. The NLCLDD will work with a NLCLDD hired Engineer (Duplantis Design Group) and the City of Thibodaux to complete these projects as required.
Rienzi Canal Maintenance Dredging: This project involves maintenance dredging and removal of the spoil for the portion of the Rienzi Canal from Highway 308 heading north approximately 2000 feet to Ashland Dr. It is expected that a portion of this work can be performed by the NLCLDD with in-house equipment.
Project COA 6500.56Z, Estimated Cost: $37,000.00
Rosedown Canal Maintenance Dredging: This project involves maintenance dredging and removal of the spoil for the portion of the Rosedown Canal approximately 330 feet east of and parallel to North Canal Blvd from Melrose Street heading north approximately 3700 feet to the Thibodaux Family Church. It is expected that a portion of this work can be performed by the NLCLDD with in-house equipment.
