Waterfront Professional Park is an approximate 10+ acre parcel in Plains, PA that is the home of both 670 South River Street, 672 South River Street, and a McDonald's. It is also the site of a 3.7 acre vacant, shovel ready development site on the north end of the complex. The site is available for sale, as a joint venture partnership, or land lease. The existing McDonald’s was completed in 2001 and was immediately followed by 670 South River Street—a 63,000 square foot office building. In 2005, 672 South River Street was completed, and tenants began occupying the 59,000 square feet in 2006. Today, both buildings are actively leased with a healthy mix of fortune 500 companies and medical tenants.
