The city of Newark pledged to contribute $210 million to the construction of the arena, using settlement money from its lease dispute over underpaid rent for use of Newark Liberty International Airport with the Port Authority of New York and New Jersey. The Devils paid for the remainder of the cost. Thus, no new direct taxpayer funding was required for the construction of the arena. Some taxpayer dollars, however, were spent on infrastructure improvements. These improvements were necessary for both the new arena and proposed private development surrounding that arena.
