The Stronach Group, a real estate development company, will consolidate racing operations in Southern California and close the Golden Gate Fields horseracing track by the end of 2023.
Horses from the Golden Gate Fields track will be transported from the Northern Californian venue down to Santa Anita Park and San Luis Rey Downs.
The company has plans to increase the fields at these two Southern Californian tracks.
For Santa Anita Park specifically, The Stronach Group is preparing to add another raceday to the weekly calendar, which will be launched in early 2024.
Belinda Stronach, Chairman, CEO and President of The Stronach Group, said: "The Stronach Group remains steadfastly committed to racing in California.
“We believe that the future success of racing depends on a business model that encourages investment in Southern California, one of North America's premier racing circuits.
“Focusing on Santa Anita Park and San Luis Rey Downs as state-of-the-art racing and training facilities that offer enhanced programme quality, increased race days, expanded wagering opportunities, and premier hospitality and entertainment experiences is vital to ensuring that California racing can continue to compete and thrive on a national level."
The Stronach Group has also released a statement, saying it will work with trainers, horses and employees during the relocation.
Stronach continued: "We recognise that the decision will have profound effects on our valued employees as well as the owners, trainers, jockeys and stable personnel at Golden Gate Fields.
“The Stronach Group is committed to honouring labour obligations and developing a meaningful transition plan.”
