Emerald Downs first opened its doors to race fans on June 20, 1996, with the inaugural 100-day meet running through November 4. It replaced Longacres Racetrack, which closed in September 1992 after sixty seasons of racing. Following the closure of Longacres , racing was not held in Western Washington from 1993–1995. However, Thoroughbred racing continued at Yakima Meadows and Playfair Race Cource in Spokane during this time. Emerald Downs operated as a Limited Partnership from 1996 to 2015, with a group of investors led by Ron Crockett. In 2002, the land where Emerald Downs is situated was purchased by the Muckelshoot Indian Tribe for roughly $70 Million. The Tribe purchased the track buildings and facilities and formed Emerald Downs Racing LLC in 2015. The Tribe has made a number of improvements since taking over the operation including a 1150 square foot infield big screen. Emerald Downs celebrates its 20th anniversary Monday, June 20 , 2016, with a special night of racing featuring many of the stars from the track's first two decades.
