1990 City of New Orleans/Orleans Parish Census data. ESRI shapefile format, GIS software required for viewing geometry (http://www.esri.com/software/arcgis/arcreader/). Tabular data (DBF), included as part of the shapefile, are viewable in Excel.

Census Tracts are small, relatively permanent statistical subdivisions of a county or statistically equivalent entity delineated by local participants as part of the U.S. Census Bureau's Participant Statistical Areas Program. The primary purpose of Census Tracts is to provide a stable set of geographic units for the presentation of decennial census data. In 1980 the New Orleans City Planning Commission, for planning and decision-making purposes, divided the city into Census Tract based 'neighborhoods'. Additional neighborhoods were created after the 1990 and 2000 Censuses. Following Hurricane Katrina the Greater New Orleans Community Data Center (GNOCDC) settled on these boundaries to facilitate the use of local data in decision-making. These neighborhoods underwent further change during the 2010 Census due to modifications (consolidation and/or splitting) of Census Tracts, the resulting boundaries were renamed as 'Neighborhood Statistical Areas' to reflect their actual function.

City of New Orleans 'Square' - A portion of property with specific street or other designated boundaries and a given alpha/numeric identification.

Hurricane Katrina of August, 2005, is remembered as one of the most destructive and influential storms in United States history. The densely populated city of New Orleans, one of many areas around the Gulf Coast to face catastrophic damage, endured extreme flooding and physical destruction when several levees and other flood prevention features guarding the city broke down. Many evacuated the city and fled to far corners of the country, and a large portion of these evacuees were unable to resettle in New Orleans after the storm. Dealing with the aftermath of Hurricane Katrina involved many immense challenges, but ten years later, one can see the effects of a decade of hard work in restoring this historic city. This series of maps tracks New Orleans through these ten years of change. The story map uses the Esri Story Map Series app, The story was produced by Esri in collaboration with the Smithsonian Institution. The story can also be found on the Smithsonian Website. Data for each map was taken from the following sources:Katrina Diaspora: 2006 American Community Survey 1-year Estimates, State-to-State Migration Flows, NHC, NOAA, NWS. Flooding: Terrestrial lidar datasets of New Orleans levee failures from Hurricane Katrina, August 29, 2005: U.S. Geological Survey Data Series, NASA Earth Observatory, NOAA National Geodetic Survey.

Overlay zoning districts are designed to require special controls in certain areas of the City that have special characteristics or special development issues. The intent of an overlay zoning district is to provide common controls over areas that require a specific type of zoning control but are typically zoned with more than one (1) base zoning district. Unless modified by the overlay zoning district regulations, the regulations of the base zoning district apply. Whenever a lot and/or development site, as defined below, is covered by more than one overlay zoning district, the regulations of each overlay zoning district shall apply, except that where the regulations of such overlay zoning districts contain an actual, implied or apparent conflict, the more restrictive regulation shall apply unless stated otherwise.
