History and overview Spring Hill was formerly a large tract of endangered Longleaf Pine Ecosystem and Sand Pine Scrub with very high biodiversity, and a safe haven for many imperiled species, and most of it remained unchanged until the 1970’s with large scale deforestation. It first appeared on Hernando County maps as early as 1856 along what is today Fort Dade Avenue just north of the community of Wiscon. The modern Spring Hill was founded in 1967 as a planned community, which was developed by the Deltona Corporation and the Mackle Brothers. The developers originally wanted to call the community Spring Lake and used that as the working name through the development process. They were forced to use a different name due to the name Spring Lake already being in use locally and chose Spring Hill. The plans for the community are identical to the community of Deltona. The Mackle Brothers sold many of the properties and land in the area through intense advertising. It has since become a sprawling semi-city in its own right, though it is an unincorporated area. The main entrance to the original development is marked by the Spring Hill waterfall on Spring Hill Drive and U.S. Route 19 (Commercial Way). Spring Hill's proximity to Tampa, to the south, and the completion of the Suncoast Parkway in 2001 have made the community easily accessible to the Tampa-St. Petersburg area.
