The term “Northshore” or “North Shore” refers to areas that lie on the northern shore of Lake Pontchartrain and includes St. Tammany Parish. The Northshore includes the communities of Mandeville, Covington, Madisonville, Abita Springs, Lacombe, Eden Isle and Slidell. Hammond and Ponchatoula, in Tangipahoa Parish, and Bogalusa and Franklinton, in Washington Parish, are also considered to have economic ties to Greater New Orleans although those parishes are frequently not included in the statistics for the New Orleans Metropolitan Area. The Northshore region is also part of the Florida Parishes, dating back to the time when the Spanish territory known as Florida extended westward all the way to the Mississippi River, including portions of what are now Alabama, Mississippi and Louisiana. St. Tammany Parish is the most affluent parish in metropolitan New Orleans and is also the most politically conservative.
