Protecting People, Property and Our Way of Life

Lockport-Larose

The boundary is the area enclosed by a polygon beginning at the intersection of Bayou Lafourche and the Company Canal in Lockport. The boundary runs generally south and east along the eastern bank of the Company Canal to the intersection of the Company Canal and the GIWW.  From there, the boundary follows the north bank of the GIWW west than turning northwest to the intersection of the GIWW and Bayou Lafourche in Larose. At this point the boundary meanders generally north and west along the west bank of Bayou Lafourche back to the point of beginning at the intersection of Bayou Lafourche and the Company Canal in Lockport. The 2010 Census shows a population of 6,385 in this Project Area which represents a 6% increase in population over the last 20 years and a 1% increase in the last 10 years.

 

Lockport to Larose Levee Project: This large project includes major maintenance and re-sectioning of the levees from Lockport to Larose along the 40 Arpent Canal and Bayou L’ Bleau. The NLLD hired J. Wayne Plaisance Engineers and David Waitz Engineers for design and surveying work for individual portions of this project. The project is underway at this time with work beginning in the Edna Plantation section near Valentine. Ultimately, the goal of this project will provide a levee with a height of 9 feet above sea level throughout its length. The current permitted project area is from the Parr Pump Station to just pass the Edgar Guidry Pump Station. Currently, the levees have been substantially completed from just east of the Edna Pump Station to the Parr Pump Station (Reaches C1, C2 & C3). The plan is to continue work to the southern permit extent. This portion of the Project is called Reach “C”.

Project COA for current work section (center) is 6300.50Z.

Estimated Cost: $38,100,000.00

This project has the following short term sub-projects within it:

Edna / Barrios Pump Relocation and Consolidation:  A consequence of the Lockport to Larose Levee Project is the need to address the location and function of both the existing Edna and Barrios Pump stations. Both stations are poorly positioned for the new levee alignment, old, and antiquated. The NLLD has completed a study of the best solutions and cost estimates for this issue. Overall, it has been determined that the best course of action would be to:

1) Remove the existing Barrios Pump Station.

2) Remove the existing Edna Pump Station and replace it with a new station at the end of the existing outfall canal. With sufficient capacity, this new pump station would allow us to:

3) Remove or re-align the existing Edgar Guidry pump station, also not properly positioned for the levee alignment especially if you:

4) Relocate the Larose Pump Station further west at the existing canal running from the 40 Arpent levee to the GIWW.

Primary funding for items 1) & 2) above is coming from the Parish HUD CDBG.  Angelette and Picciola has been selected as engineer for the project and the NLLD is monitoring and is involved in the project scope and details as well as technical support and review as it moves forward.

Reaches C4 (Phillip Plaisance to the Edgar Guidry Pump Station), C5 (Edgar Guidry Pump Station to the end of the permit at Defilice) and Reach D1 (described below) will require a different method of construction as compared to reaches C1-C3.  The NLLD has engaged John Plaisance, Neil Angelette and others, plus geotechnical experts to determine the best course of action for this very challenging section of levee. The goal is to develop plans for a levee to a stable +7’ elevation throughout Reaches C4, C5 and D1 that can be practically maintained for the next 15 to 20 years.  A recommendation towards the design and location of this levees system has been made by the Engineers and accepted by the NLLD. The NLLD plans to hold a series of public meetings to explain the construction design and material requirements. After receiving public input and answering any questions, the District will pursue Rights of Ways from impacted landowners in the area. It is hoped that the project remains practical and that the residents and businesses of the area will be able to benefit from an improved levee system.

Continuity of Levee at Allied Shipyards: There exist a low area in the current Lockport to Larose flood protection (also known as reach D4) where the existing levee near Larose fails to connect to the 7 foot contour along the GIWW and Bayou Lafourche. Just prior to Hurricane Ike, the NLLD installed HESCO bags to close this gap. Gaps in these bags were re-installed for Tropical Storm Lee and Hurricane Isaac. NLLD hired J. Wayne Plaisance Engineers as engineers for this project and they have been working with local property owners to provide a permanent and easily deployed solution to this situation. The project was advertised and has been awarded to Sea Level Construction for $426,610.00. The project should be completed in April or May of 2014.

Repairs of Weakened Levee Sections Valentine to Larose: The section of levee along the 40 Arpent Canal from Valentine to Larose was poorly constructed and previously modified by removing the protected side berm. This causes a continuous maintenance requirement until the levee can be re-constructed as part of the Lockport to Larose Levee Project as described below as Reach “D”. The NLLD Deep-water Excavator, along with a LPG small track excavator completed a keying and recapping project in the summer of 2010. This levee reach has been re-sectioned as the material dried and settled. Subsequently, the NLLD Lockport to Larose Levee Project Committee decided to consider an engineered solution for the 2000 foot problematic section. An emergency action opportunity caused by the opening of the Morganza Spillway allowed the Parish, the NLLD, and the State to specifically address the weakened sections with work completing on 6/10/2011. The committee continued to consider temporary action in this area. Work was planned and was budgeted for the winter of 2011/2012. Engineering design and geotechnical was completed to make the interim repairs and the local impacted landowners had been contacted for RoW donations. Due to a lack of donations of borrow materials, the designed interim solution cost had increased to an estimated $1,000,000.00.   As such, the NLLD proposed a project with shared cost whereby the NLLD contributed $500,000.00, with the balance of the funds coming from the Parish or the State. The NLLD has received notice of an additional $500,000.00 in funding from the State Coastal Protection and Restoration Authority (CPRA).  The NLCLDD has hired Picciola and Associates as an engineer to design and advertise / bid  this project to address this issue as rapidly as possible. The Project has been awarded to Apeck Construction and work on the project construction has been completed. Because the original bid amount was less than the $1,000,000 available, the contract was extended to repair another weakened section and adjacent levee in that area.

Maintenance to the return Levee at Phillip Plaisance:  This project involves re-sectioning a section of levee between Bayou L’ Bleau and the 5 foot contour line near Bayou Lafourche adjacent to the Phillip Plaisance property. Most of this project area is on land owned by ConocoPhillips and Phillip Plaisance. The NLLD is working with the landowners to develop project specifics. The section from Bayou L’ Bleau to the 40 Arpent Canal has been improved using material from the inside and in house equipment.  The project includes a return levee to the 5 foot contour along Bayou Lafourche and a gated culvert across the new Borrow Canal. The NLLD will be engaging an Engineer to develop the scope for this project.

This project has the following longer term sub-projects within it:

Smithport Levee Lift (North End): Also known as “Lift A1”. This project includes adding height to the Smithport Levee along the back side of Lockport from the Company Canal to the Al Robichaux Pump Road Gate. A recently completed project brought the elevation of this levee to a 5’ elevation throughout its length and addressed issues with the culverts through this levee system. The Levee District completed the work in this project area by using a portion of the funds made available through 2010 / 2011 State Capital Outlay funds along with District funds. The District intends to provide a hauled in future lift to a 7.5’ elevation to match the planed second levee lift at the Company Canal once the material has had time to settle from this most recent lift.
