The bill amends R.S. 33:4071(A)(1)(b) and enacts R.S. 33:4071.2, focusing on the New Orleans Sewerage and Water Board's responsibilities regarding drainage operations and flood prevention. It modifies the composition of the Sewerage and Water Board by allowing the chair of the Public Works, Sanitation and Environment Committee of the New Orleans city council to appoint a representative with expertise in engineering, law, or consumer advocacy, with the council's advice and consent. Additionally, the bill establishes a requirement for quarterly meetings among various state and local agencies to develop a coordinated flood prevention plan, which will be presented annually to the New Orleans Delegation and city council starting in 2025.

Furthermore, the bill designates the Sewerage and Water Board as responsible for all drainage operations in New Orleans, mandating the transfer of relevant employees and equipment from the city. It stipulates that the city must allocate annual funding to the Board equivalent to what was used by the New Orleans Department of Public Works for drainage in fiscal year 2023, with any additional funding requiring city council approval. The bill also calls for cooperative agreements between the city, the Sewerage and Water Board, and the Coastal Protection and Restoration Authority to manage federal disaster resilience funds and outlines the Board's collaboration with the Louisiana Department of Transportation and Development on significant capital improvement projects.
