Some St. Tammany residents have filed a lawsuit to block the rezoning of 70 acres south of Covington, between Ochsner Boulevard and I-12, where the medical supply company Medline plans to build an 800,000-square-foot distribution center. Medline currently operates a 200,000-square-foot distribution center just across I-12 from the proposed site. The suit in the 22nd Judicial District Court challenges the Parish Council’s zoning decision back in December. The plaintiffs argue that the zoning move violates the parish’s comprehensive zoning plan and is being made only to benefit Medline and the property’s owner, All State Financial Company. Opponents turned out at Parish Council meetings late last year to object to the zoning change, arguing that the proposed facility would greatly increase traffic in a dangerously congested area and increase the risk of flooding.
