BATON ROUGE, La. (The Advocate) — A group of Louisiana flood victims who have been owed over $300 million for the past decade have filed a lawsuit against the state for failure to pay.

The Advocate reports Tangipahoa Parish home and small business owners who flooded in 1983 filed the lawsuit in U.S. District Court in Baton Rouge on Thursday. The latest lawsuit comes over a decade after residents won a case which found the construction of a local highway blocked drainage of the Tangipahoa River.

The court ruled the state failed to conduct needed studies on the river, and ordered Louisiana to pay millions in damages plus other costs and interest.
