St. Johns Properties Inc., a Baltimore-based commercial real estate developer, has broken ground on a new $31 million office park that will add more than 313,000 square feet of flex-office space in Anne Arundel County.

Called Arundel Overlook, the 68-acre park is located near the intersections of MD 100 and MD 295 and is adjacent to the Arundel Mills shopping mall. It marks the developer?s 12th business park in the county and the sixth in the Baltimore/Washington International Thurgood Marshall Airport submarket.
