Dan Cohen AUTHOR Washington County has agreed to sell the remaining 528 acres at the former Fort Ritchie in central Maryland to South Korean investment group Issac Holdings for $6 million. The county gave JG Business Link International, the master developer it hired two years ago, the site’s other 63 acres last year to jump start development. JGBLI, which will continue to develop the property for Issac, plans to attract $1.5 billion of investment to build the Cascade Town Centre, a mixed-use development with academic, commercial, residential and recreational uses. “If they’re able to do half what they laid out, it will be one of the major investments and success stories in the region,” L. Michael Ross, president of the Franklin County (Pa.) Area Development Corp., told the Public Opinion. … The Environmental Protection Agency presented its first annual National Federal Facility Excellence in Site Reuse award during a ceremony last week to the former McClellan AFB, Calif., in recognition of the combined efforts of the Air Force Civil Engineer Center, McClellan Business Park (the reuse project) and Sacramento County to transform the Superfund site into a 3,452-acre business park which now supports more than 17,000 jobs and has generated $580 million in public and private investment. “This award celebrates hard work, innovative thinking, and cooperation among federal agencies, states, local partners and developers,” said John Henderson, assistant secretary for installations, environment and energy, according to an EPA release. Two other base reuse projects received the award as well — Naval Air Station Glenview, Ill. (The Glen), and Joliet Army Ammunition Plant, Ill.
