Richland Communities plans a massive office campus along Highway 65 that will hopefully attract more corporate headquarters to Roseville. The 1.2 million-square-foot development – that’s larger than the nearby Westfield Galleria shopping center – would include about two dozen office buildings and some retail shops. The $100 million project, known as Highland Reserve South, revises a plan the company submitted a year ago. Richland bought the 2,000 acres near Washington Boulevard in 1995, and has developed all but the 115 acres reserved for the campus. Two months ago, Mac Millan Partners announced plans for a 1.1 million-square-foot office complex in Roseville. The two campuses would help the city lure more corporate headquarters and create more jobs. This is Ron Trujillo for the Business Journal.
