Boat into concerts? That's the plan for First Avenue's amphitheater proposal

Over a mile of riverfront in north Minneapolis could become home to a First Avenue-operated amphitheater, hundreds of homes and thousands of square feet for business.

The city and several partners have unveiled plans for redeveloping the 48-acre Upper Harbor Terminal site between the Lowry and Camden bridges along the Mississippi River.

The plan for the whole site includes these features:

• 700 to 1,000 homes

• 100,000 to 150,000 square feet of "creative office space"

• 40,000 to 70,000 square feet of retail space

• 180,000 square feet for "advanced manufacturing"

• An 8,000- to 10,000-seat entertainment venue

The proposed development would also have public green space and a 100-foot riverwalk.
