MARRIOTT-SLATERVILLE, Utah, October 05, 2022--(BUSINESS WIRE)--St. John Properties has broken ground on its fourth Utah development, and its first construction project north of Salt Lake City in Weber County, Utah.

Once completed, the 19-acre business community will offer 170,000 square feet of commercial flex/R&D and retail space.
