List of United States cities by area says Sitka Alaska has 4 812 square miles of which 2 874 are land Juneau Alaska has 3 255 square miles of which 2 717 are land Anchorage Alaska has 1 961 square miles of which 1 697 are land and Jacksonville Florida has 874 square miles of which 758 are land List of cities by surface area matches that except that it mentions Juneau City and Borough The pages about those four individual cities today have figures that match too Yet when I posted in this section several days ago the article on Jacksonville said 1 962 4 square miles Jacksonville s own government website says it has 841 square miles not 874 or 758 I m not sure whether some people or governments are rightly or wrongly putting all of a county s land into the city s listed area I can say that in the case of Jacksonville although the governments of the a City of Jacksonville and b Duval County are unified there is or ought to be separate reckoning of the city s and county s area because Duval County also contains three other cities Jacksonville Beach Atlantic Beach and Neptune Beach which are not part of the City of Jacksonville they have their own separate police departments for example even though the Jacksonville Public Library is county wide The government website of the City and Borough of Juneau says it has 2 593 6 square miles of land and 487 6 square miles of water for a total of 3 081 2 square miles Neither the total nor the land area there matches what Wikipedia gives At the government website of the City and Borough of Sitka I haven t found the area Same for the government website of Anchorage But it does link to anchorage net which says the city has 1 955 square miles which like the government figures for Jacksonville and Juneau doesn t match Wikipedia s figure
