Seaside is an unincorporated master-planned community on the Florida Panhandle in Walton County, between Panama City Beach and Destin. The population of the city is 12,090 residents. One of the first communities in America designed on the principles of New Urbanism, the town has become the topic of slide lectures in architectural schools and in housing-industry magazines, and is visited by design professionals from all over the United States. On April 18, 2012, the American Institute of Architects's Florida Chapter placed the community on its list of Florida Architecture: 100 Years. 100 Places as the Seaside – New Urbanism Township.
