NARRATIVE DESCRIPTION:

1. A description of each activity, including the need, purpose, objective(s), milestones and location. Include map showing the 

location of each activity.

Terrebonne Parish is removing the North Lake Boudreaux Forced Drainage/Flood Risk Reduction Project from its 

Multiyear Implementation Plan (MYIP) and is adding another project in this amended MYIP (Amendment No. 01). 

The North Lake Boudreaux Forced Drainage/Flood Risk Reduction Project is being removed because of a lack of 

sufficient local and state funds necessary to supplement available RESTORE Act funding to undertake and complete 

this project.

Amendment No. 01 of this Multiyear Implementation Plan contains one new project which is eligible for RESTORE Act 

Direct Component funding. This new project is the Bayou Little Caillou Flood Risk Reduction System (Pump Station and 

Conveyance Channel).

Bayou Little Caillou Flood Risk Reduction System (Pump Station and Conveyance Channel):

Description: This new project entails the construction of a conveyance channel and drainage pump station in the Lower 

Little Caillou (5-1A) Forced Drainage Basin on property owned by Terrebonne Parish Consolidated Government as part 

of the Terrebonne Parish Hurricane/Flood Risk Reduction Levee and Forced Drainage System. This basin has been 

closed-in by a series of levees and a floodgate that in tandem prevents excessive rainfall runoff from escaping the basin. 

When storms, such as hurricanes and other severe weather events approach the area, floodgates, including the one on 

Bayou Little Caillou, are closed to prevent storm surge flooding and saltwater intrusion. When such closures are coupled 

with excessive rainfall events, the existing pumping capacity within the 5-1A system is insufficient to prevent flooding in 

the basin. The proposed conveyance channel and pump station will divert freshwater from Bayou Little Caillou into the 

Lake Boudreaux basin to the west, thus reducing the threat of backwater flooding from an excessive rainfall event 

within the 5-1A system. This project will also have a secondary beneficial effect. The introduction of freshwater into the 

Lake Boudreaux basin will help to move the salinity gradient further to the south in this lake and spur the growth of 

freshwater vegetation in this area and eventually reduce the amount of open water in the lake.

This project represents critical coastal flood protection and related infrastructure that is designed to provide the 

affected coastal community with redundant flood risk reduction and protection. The proposed project will consist of a 

pump station with four (4) 48-inch vertical axial pumps with electric motors with the ability to move 450 cubic feet of 

water per second (cfs). The project also includes a 20 ft. wide conveyance channel from Bayou Little Caillou to the 

pump station, four (4) box culverts and sluice gates to convey flow from Bayou Little Caillou under LA Hwy 56 to the 

pump station, and an access road to the pump station. See Site Map.

Need: With its location along the Louisiana coast, Terrebonne Parish is susceptible to tidal flooding from storm surge 

generated by Gulf of Mexico hurricanes and other storm events. Such flooding events are common and have been 

frequent. For nearly 50 years, therefore, Terrebonne Parish as worked to build flood protection systems and 

infrastructure for its citizens. This is the general need for this project, but the specific need for this project is seen in the 

fact that the Little Caillou Basin has been closed-in over the years by a series of levees and floodgates that are designed 

to prevent storm surge from flooding the structures and homes behind these protective structures. When all existing 

flood risk reduction components have been activated, however, the basin does not have the ability to drain excess 

water from the protected areas in the event of a concentrated rainfall event. This has led to flooding in the basin as 

water becomes trapped. Engineering analysis has been undertaken to evaluate peak runoff conditions in the 5-1A 

drainage basin, concluding that the conveyance channel and its pump station are necessary to prevent this type of 

flooding under the conditions described that also includes runoff from the Smithridge, Ward 7, Aragon, and LaCache 

Drainage Basins all of which pump directly into Bayou Little Caillou. 

Purpose: This project will address several critical purposes in the Terrebonne Basin. It consists of construction of a 

pump station and the dredging of a conveyance channel to convey storm water from Bayou Little Caillou and the 

protected areas of Terrebonne Parish to Lake Boudreaux and eventually to the Houma Navigation Canal. The addition 

of a new pump station in the Lower Little Caillou Forced Drainage area will serve two main purposes. First, it will serve 

as a bypass pump station to convey storm water from Bayou Little Caillou that is discharged from the various basins 

mentioned above. All these basins are served by pump stations. The proposed pump station and conveyance channel, 

in the event of floodgate closure in advance of storm surge AND a significant rain event inside the system, will provide 

for the protection of life and property in the area by greatly reducing the chances of flooding which will afford the 

impacted communities and the parish a higher level of resiliency. This project will also lower the risk to life and 

property associated with relative sea level rise, subsidence, and tropical events that impact this area from time to time. 

In general, it will improve the long-term economic health of the parish and region.

Objectives: Construction of the proposed Bayou Little Caillou Flood Risk Reduction Project (both pump station and 

conveyance channel) will be critical to the overall success of the project. To that end, the project will aim to maximize 

benefits to life and property. The objectives of the project are the following: 1) Alleviate back water flooding within the 

levee system by constructing the pump station/conveyance channel. 2) Provide a vital link in the parish’s overall flood 

risk reduction system, thus reducing vulnerability to life and property from storm-related flooding. And 3) Increase 

resiliency and sustainability in the parish. In order to meet these important objectives, the pump station will be 

constructed at an elevation of +11.00 feet and will consist of four (4) 48-inch vertical axial pumps with electric motors 

supplemented with diesel back-up generators. The construction of the station includes sheet piling and slab, a 20 ft. 

wide conveyance channel from Bayou Little Caillou with box culverts under Hwy 56. The box culverts will be fitted with 

sluice gates to control the flow of water into the conveyance channel. The pump station will be accessed by a 15 ft. 

wide gravel road which will be gated to exclude unauthorized access. The pump station is being designed to discharge 

water into Lake Boudreaux at a rate of 450 cfs that will offset the amount of water that is pumped into Bayou Little 

Caillou from the drainage basins located upstream. The proposed project (pump station and conveyance channel) will 

prevent flooding of adjacent areas during storm events which precipitate the closure of the Bayou Little Caillou Sector 

Gate.

3. How each activity included in the applicant's multiyear plan narrative meets all the requirements under the RESTORE Act, 

including a description of how each activity is eligible for funding based on the geographic location of each activity and how each 

activity qualifies for at least one of the eligible activities under the RESTORE Act.

The project described herein and included in this amendment to the Parish MYIP for the use of its Direct Component 

RESTORE Act funds is designed to generate benefits that will accrue to a Louisiana parish located along the Gulf of 

Mexico that was impacted by the BP/Deep Water Horizon Oil Spill in 2010. Not only is Terrebonne Parish located in the 

Louisiana Coastal Zone, but is also situated on the Gulf of Mexico. This makes projects that are otherwise eligible for 

funding under the RESTORE Act also eligible by virtue of their geographic location. 

The Bayou Little Caillou Flood Risk Reduction System (Pump Station and Conveyance Channel) is an eligible activity since 

it is a coastal flood protection and related infrastructure project. The construction of the proposed 450 cfs pump 

station and conveyance channel will provide for the protection of life and property in the area by greatly reducing the 

chances of flooding, thereby providing the impacted communities and the parish a higher level of resiliency. This 

project will also lower the risk to life and property associated with relative sea level rise, subsidence, and tropical events 
that impact this area from time to time. In general, this project will improve the long-term economic health of the 

parish and region.

4. Criteria the applicant will use to evaluate the success of the activities included in the multiyear plan narrative in helping to restore 

and protect the Gulf Coast Region impacted by the Deepwater Horizon oil spill.

Bayou Little Caillou Flood Risk Reduction System (Pump Station and Conveyance Channel):

The success of this project will be evaluated by construction of the 450 cfs pump station and conveyance channel that 

will lead to the reduction in flood events from storm surge and storm-related flooding events in this region of the 

parish.

5. How the activities included in the multiyear plan narrative were prioritized and list the criteria used to establish the priorities.

Bayou Little Caillou Flood Risk Reduction System (Pump Station and Conveyance Channel):

Flood risk reduction has always been an overarching priority for Terrebonne Parish for a very long time. It continues to 

be an important priority since all the components of our flood risk reduction system are not yet in place. Terrebonne 

Parish Administration, with the full support of the Parish Council, has budgeted funds on an annual basis to address this 

important priority. Virtually every annual parish budget contains funds to address one or more components of our 

flood risk reduction system. With the completion of the Bayou Little Caillou Sector Gate designed to stop storm surge 

and reduce saltwater intrusion, the potential for backfill flooding in the Bayou Little Caillou basin is significant. Other 

storm water drainage systems pump water into Bayou Little Caillou, but when the sector gate is closed to counter storm 

surge, water in the system generated by a rain storm cannot be removed. In these circumstances homes and 

businesses in this basin as susceptible to flooding. To alleviate this situation, the parish hired an engineering firm to 

design and engineer the pump station and conveyance channel. Although Terrebonne Parish has invested parish funds 

and has budgeted additional parish funds towards this project, these funds are insufficient to complete it. The parish’s 

currently allocated RESTORE Act Direct Component funds will allow the parish to complete this high priority flood risk 

reduction project.

6. If applicable, describe the amount and current status of funding from other sources (e.g., other RESTORE Act contribution, other 

third party contribution) and provide a description of the specific portion of the project to be funded by the RESTORE Act Direct 

Component.

Bayou Little Caillou Flood Risk Reduction System (Pump Station and Conveyance Channel):

The all-inclusive project cost estimate for this flood risk reduction project is $11,874,832, which includes $250,000 in 

compensatory mitigation to be paid with local funds. Third party funding sources, both state and local, amount to 

$9,189,307. These funds have been committed. The components of this project to be paid for with RESTORE Act Direct 

Component funds include the Conveyance Channel and its Access Road ($845,525) and the Electrical Vertical Axial Flow 

Pumps ($1,840,000) which equals $2,685,525.
