Harbour Island is situated adjacent to Downtown across the Garrison Channel. Other nearby areas include Davis Islands and Channelside. The Tampa Convention Center is located directly across the Harbour Island Bridge and Channelside is just across Beneficial Drive, both walking distance.
Harbour Island was originally known as Seddon Island, which was named after W. L. Seddon, chief engineer for the Seaboard Air Line Railway. In 1906, a public hearing was held to plan a new port for the city. Seddon's plans were adopted and soon his company dredged a channel and established a port facility on what was then called Grassy Island. The Seaboard Coast Line later sold the 177 acres (72 ha) island to the Beneficial Land Corporation in 1979 for residential, office and retail development purposes.
Today, the island consists of mostly private residential areas, including high-rise condos, apartments, row houses, single-family homes and large houses, as well as a yacht club. Amalie Arena is also located within walking distance.
Primarily served by Plant High School, Wilson Middle School and Gorrie Elementary School.
Additionally there are several nearby private schools including: Tampa Preparatory School, Berkeley Preparatory School, Tampa Catholic School, Academy of the Holy Names, Jesuit School, Sacred Heart Academy.
