House Bill No. [insert number] aims to address flooding mitigation along the Interstate 12 corridor in Livingston Parish by requiring the Department of Transportation and Development to develop and analyze various engineering methods. The bill amends the heading of Part IV of Chapter 3 of Title 32 of the Louisiana Revised Statutes, changing it from "Passing School Vehicles" to "Interstate Flooding Mitigation." It enacts R.S. 32:481, which mandates the department to conduct a comprehensive analysis of practical and cost-effective engineering solutions, including those used in other states like Texas, and to assess projected costs and construction timelines for these methods.

The department is tasked with submitting a report detailing the comparative analysis of potential flood mitigation solutions to the House and Senate Committees on Transportation, Highways, and Public Works by October 1, 2023. The bill emphasizes the importance of improving water drainage issues caused by impediments to natural water flow and may include retrofitting existing median walls along the corridor. The act will take effect upon the governor's signature or after the designated period for bills to become law without a signature.
