The ownership group looking to bring an expansion NHL team to Seattle unveiled plans Monday for a $70 million training facility in the northern part of the city.

NHL Seattle CEO Tod Lewieke announced the plans, which include three full-sized rinks and office space to serve as the headquarters for the proposed new franchise. The facility will have 180,000 square feet total and be located near Seattle's Northgate Mall, which is being redeveloped. The location is a short walk from a new light-rail station set to open in a few years and has easy access to Interstate 5.
