Osborne Reef is an artificial reef off the coast of Fort Lauderdale, Florida. Originally constructed of concrete jacks, it was the subject of an ambitious expansion project utilizing old and discarded tires. The expansion ultimately failed, and the reef has come to be considered an environmental disaster—ultimately doing more harm than good in the coastal Florida waters. In 2007, after several false starts, cleanup efforts began when the United States military took on the project. This cleanup exercise provided the military with a real-world training environment for their diving and recovery personnel, coupled with the benefit of helping the Florida coast without incurring significant costs to the state. In 2015, a civilian corporation took over, and had finally removed one third of the tires by November 2019. Construction The reef was originally constructed of concrete jacks in a diameter circle. Expansion In 1972, Broward Artificial Reef Inc. (BARINC) proposed the construction of an enlarged artificial reef to Broward County as a way to both dispose of old tires as well as lure more game fish to the area. Similarly designed reefs had already been constructed in the Northeastern United States, the neighboring Gulf of Mexico, Indonesia, Malaysia, Australia, and Africa. Gregory McIntosh, a BARINC employee, lauded the project to the attendees of a 1974 conference on artificial reefs: "Tires, which were an esthetic pollutant ashore, could be recycled, so to speak, to build a fishing reef at sea." With endorsement of the project by the US Army Corps of Engineers, the Broward County government approved the project in 1974. That spring, more than 100 privately owned boats enthusiastically volunteered to assist with the project; accompanied by the US Navy's , thousands of tire bundles were simultaneously dropped onto the reef. The Goodyear Tire and Rubber Company provided equipment for the auspicious undertaking, even supporting the project so far as to drop a gold-painted tire from a Goodyear Blimp to christen the site. The culmination of the project was the deposit of over two million tires bound with steel clips over of the ocean floor, approximately offshore, and at a depth of . Failure Ultimately, little marine life has been successful in latching onto the man-made reef and the majority never even had the opportunity to do so. When deposited, while a few tires were individual loose entities, the majority were bound together with nylon or steel clips (or bands). As
