New Orleans urban sprawl, 1970-2000
Urban sprawl was limited to areas covered under the HPS. Limited urban
development occurred following the partial enclosure of the East Bank of St Charles
Parish, but it is on the north shore of Lake Pontchartrain that urban sprawl was most
evident. Urban sprawl in St Tammany Parish is the result of the opening in 1956 of
the Lake Pontchartrain Causeway, a 35-km causeway linking Metairie on the south
shore of Lake Pontchartrain and Mandeville to the North, and the opening, two years

Bernard parishes stabilized by 1980, the St Tammany Parish population doubled
between 1980 and 2005, from 110,000 to 220,000. The depopulation of the city of
