A number of major planning efforts have been undertaken since Katrina, with varying degrees of official sponsorship and resident input, to guide New Orlean's recovery and redevelopment efforts. The most significant of these were reports by the Urban Land Institute (ULI), issued in November 2005, and Mayor Ray Nagin's Bring New Orleans Back Commission, released in January. ACORN, the grassroots organizing group, held its own planning forum in November and has incorporated some of the findings from that event into its work in New Orleans. However, while planners and developers redraw the city map, displaced residents struggle to have a role.
