The Mills Corp., a real estate investment trust with waterfront projects in Boston, Baltimore and Miami, is proposing 250,000-sf of office space, a 100,000-sf YMCA facility, 120,000-sf of "recreational retail" space and 80,000-sf of cafes and restaurants. "Recreational retail" is referred to as stores that offer some type of recreation in addition to selling product, like an outdoor equipment store with a rock-climbing wall.

Chelsea Piers' plan would cost around $100 million to develop and would feature a field house, ice rinks, bowling, an extreme park that will offer inline skating, a ropes course and rock climbing, totaling more than 500,000-sf, according to David Tewsbury, executive vice president for Chelsea Piers, who likened it to the company's facility on the Hudson River in New York. San Francisco-based Western Athletic Clubs, which was originally going to submit its own proposal, has partnered up with Chelsea Piers to build a new health club on the proposed site.
