St. Mary signs on to Acadiana Watershed District
The St. Mary Parish Council has signed on to be part of a regional effort to control flooding.
The council on Feb. 14 approved participation in the Acadiana Watershed District, part of an initiative launched after devastating Louisiana floods in 2016.
That was the Louisiana Watershed Initiative, created by then-Gov. John Bel Edwards in 2018. Its purpose, according to the initiative’s website, is “pursuing a holistic approach to watershed management, one that goes beyond conventional mitigation measures and incorporates nature-based solutions. LWI is also developing computer models to better understand flood risk and help select projects best suited for investment in each watershed region.”
The initiative received a $1.2 billion federal grant.
The state is divided into nine watershed regions. In Region 5, which includes St. Mary west of the Atchafalaya as well as 15 Acadiana parishes, Act 323 of the 2023 Legislature created the Acadiana Watershed District. It’s that district that the council voted to be part of Wednesday.
Each of the parishes will send its chief executive or a designee to serve on a board that will be able to plan and coordinate watershed-wide projects and decide how to spend grant money it obtains.
Lining up participation in the Region 5 district has been the work of the Acadiana Planning Commission in Lafayette. That’s where the Acadiana Watershed District would be based.
“We can’t solve everything,” Kelia Bingham of the Acadiana Planning Commission told the Parish Council. “But if we’re talking, that’s better than not talking.”
The district’s purpose, according to Act 323, introduced by then-state Sen. Fred Mills of Parks:
—To participate in any program promoting better drainage and reduction of flood risk.
—To promote a unified approach to reducing flood risk and improving drainage.
—To identify local sources of funding that can be used to match grants.
—To cooperate with local, state and federal authorities on mitigation projects.
In the Louisiana Watershed Initiative, St. Mary Parish is split between Region 5 and Region 6, which includes the Atchafalaya and extends east into the Terrebonne-Lafourche area.
The Acadiana Watershed District is the second such district to be created among the regions outlined by the Louisiana Watershed Initiative. No such district has yet been established for District 6.
Tim Matte, the executive director of the St. Mary Parish Levee District, has been part of planning in both those watershed zones. His advice to the parish government was to participate.
The watersheds tend to be interconnected, so the solutions can involve more than one parish. One example is the $80 million Bayou Chene Flood Control Project, an enormous flood gate located in St. Mary but which can alleviate flooding in six parishes
Matte gave another example. In Lafayette, the concern about flooding often centers on the Vermilion River. Overflow from the Vermilion can make its way to the Teche.
“Whatever comes down the Teche comes all the way to the Charenton Canal and the Wax Lake Outlet,” Matte said.
