Landrieu obtained federal funds for the revitalization of New Orleans' poor neighborhoods, and he promoted the involvement of minority-owned businesses in the city's economic life. Like his predecessor, Landrieu presided over continued suburban-style growth in the Algiers and New Orleans East districts, with Algiers essentially built-out, having exited its greenfield development stage, by the end of his administration. Landrieu was also involved in the planning and construction of the Louisiana Superdome, the Piazza d'Italia, and other projects designed to improve the economy of New Orleans. He advocated the creation of the Downtown Development District to revitalize the New Orleans CBD, and worked to promote the city's tourism industry. His tourism-related projects included the Moon Walk, a riverfront promenade facing the French Quarter, the Louisiana Superdome, as well as renovations of the French Market and Jackson Square.
