The costs of acquiring land needed to build the Washington Nationals ballpark have exceeded original estimates by $50 million, busting the publicly financed stadium’s $631 million budget with more increases yet to come, documents show.

Thanks almost entirely to land acquisition, the tab for the stadium is now pegged at $674 million, an increase of $43.2 million over the original budget, according to a Jan. 16 report provided to the D.C. Council by the D.C. Sports and Entertainment Commission.
