The construction of this flood gate is scheduled for the next two years on the Delcambre Canal. On the right side, there is a barge that will be used to block the water between the gates. Vermilion Parish aims to replicate this floodgate design on the Boston Canal and the Bayou Tigre in the future.
Could some kind of flood protection system be coming to Vermilion Parish?
Vermilion Parish is taking steps to mitigate future storm surges by proposing a plan to install three floodgates on three navigable waters in lower Vermilion Parish and construct a dirt levee.
The Vermilion Parish Police Jury approved a Master Plan that calls for building a protection levee just north of the Intracoastal Canal and three floodgates to prevent storm surges from moving north from the Vermilion Bay.
The goal is to first build floodgates on the Bayou Tigre, Boston Canal, and the Vermilion River, located by Omega Protein.
The floodgates for the Bayou Tigre and Boston Canal would each cost around $15 million, while the
floodgate for the Vermilion River is projected to cost around $70 million.
The three floodgates would cost nearly $100 million. The parish would seek federal and state funds to pay for the three structures.
This past week, members of the Vermilion Parish Coastal Restoration Board and police jurors visited South Terrebonne and Lafourche parishes to see what type of protection levee system the parishes have built over the last 20 years at a cost of $1.5 billion.
The levee system protects 250,000 people in two parishes.
The flood gates structures also helped bring down flood insurance rates to homes located inside the levee system.
The Vermilion Parish representatives on the tour saw different locks and floodgates built in the last 20 years.
Giving the tour was GIS Engineering, who designed the floodgates for the parishes.
Vermilion Parish officials are looking to step up their game and develop a flood protection plan because of what is happening in Iberia and Cameron parishes.
Cameron Parish recently built a $9 million levee that begins at the Vermilion Parish line.
In the next two years, the state’s Coastal Protection and Restoration Authority (CPRA) will help fund a floodgate project on the Delcambre Canal in Iberia Parish, located south of the Intracoastal Canal.
The cost of the project could be around $20 million.
The floodgate will be a barge that will remain open for boat traffic. If a tropical storm or hurricane in the Gulf of Mexico causes flooding from a storm surge and floods Delcambre or the area south of Delcambre, the flood gates can be closed to prevent water from coming up the Delcambre Canal.
After Iberia Parish completes the floodgate building, it will move to Vermilion Parish.
CPRA officials will attend a police jury meeting early in November to introduce the engineering firm that will design floodgates or possibly an earthen dirt levee to be built in Vermilion Parish.
Vermilion Parish Coastal Restoration Board Vice President Chad Leger, who is also a police juror, enjoyed the tour.
“It was a nice tour,” said Lege. “We are able to see flood protection structures and I like their design. Vermilion Parish needs this. We also learned that these structures helped bring down flood insurance rates.”
Abbeville’s Cobb Lebouef, a member of the Vermilion Restoration Board, toured the structures. He said he would love to see three floodgates and a levee built.
The earthen dirt levee would protect homes in the Henry and Forked Island area and the agriculture industry south of Abbeville.
“Vermilion Parish needs this to protect everything from homes, businesses, and its agriculture industry,” said LeBouef.
