The company has bought 11 acres, including the former Cargo Largo store on Watt Avenue, just north of Interstate 80. Wal-Mart wants to demolish the former Cargo Largo building and replace it with a 147,000-square-foot supercenter. Sacramento County officials are cautiously optimistic about the project, which could help jump-start development in the area along Watt Avenue. But the retailer must complete environmental and traffic reports for the site, before the project can move forward. Wal-Mart has 14 stores in the four-county region, including two less than five miles from the Watt Avenue site. That figure includes four supercenters – one on Antelope Road in Sacramento, and one each in Citrus Heights, Roseville and West Sacramento.
