History
Before the early 1950s, Shelter Key was a low-lying island. Then, Phil Sadowski began dredging around the island, adding to its size and increasing its height to above mean sea level, and later built developments on the island. Around 1956–1957, residents of nearby Marathon began discussing incorporating the entire area. Sadowski was not keen on having his development swallowed up into Marathon, so he began the process of incorporating the island into its own city. The Florida Legislature passed legislation in June 1957 allowing incorporation, which local residents passed unanimously in September, thus creating today's Key Colony Beach. Incorporation became a blessing in 1960, when much of the city was destroyed by Hurricane Donna. As a separately incorporated city, Key Colony Beach received its own federal grant to rebuild; nearby Marathon had to settle for a portion of the grant given to Monroe County. However, the storm depressed real estate prices, and it took several years to for prices to stabilize.
Geographical layout
Key Colony Beach is reached over the Sadowski Causeway, which connects Key Colony Beach to Marathon, on the east side of the city. It lies directly south of the City of Marathon, spanning a narrow cut. Along the causeway are some charter fishing boats and a dockside restaurant called Sparky's Landing. At the base of the causeway, West Ocean Drive branches off first to the right and East Ocean Drive soon after branches to the left. On West Ocean Drive is the police station, along with the post office and town hall. In the same vicinity is a small park with a fountain and a gazebo. The entire ocean-facing side of West Ocean Drive is lined by various condominium complexes, while the side facing Marathon houses the Key Colony Inn and a par 3 golf course. Starting at the far end of East Ocean Drive, streets are numbered one to fifteen east to west, and run from south to north toward Shelter Bay. The most notable buildings along East Ocean Drive are the Key Colony Beach Motel and the Key Colony Beach Club. At the tip of West Ocean Drive is Sunset Park, the place closest to where a woman was fatally struck by a spotted eagle ray. Many news reports were recorded from this park overlooking the shallows where the Vaca Cut meets the Atlantic Ocean.
