San Bernardino County will become the first Southern California Topgolf location. Construction begins this month on the 600,000-square foot facility, with completion anticipated for early 2022. The development is on 13.7 acres of undeveloped County-owned land adjacent to Cucamonga-Guasti Regional Park at the corner of Archibald Avenue and Fourth Street in the City of Ontario. The agreement will bring in more than $625,000 annually to support our County’s regional parks system.
