NEW YORK, NY July 24, 2009 —The Port Authority says it's found a way to resolve a situation that was costing it some $300,000 a day.

The authority was supposed to turn over two building sites at the World Trade Center site to developer Larry Silverstein more than a year ago. But a small piece of the property was occupied by a retaining wall.

Port Authority Executive Director Chris Ward said engineers figured out how to move the wall 10 feet to the west without disturbing the subway tunnel behind it.

WARD: This has been a process which has clearly has evolved.

REPORTER: Under their contract, The Port Authority has been paying Silverstein $300,000 for each day after the July 1st, 2008 deadline that it has failed to turn over the sites. The authority estimates it'll pay more than $130 million before it finally finishes the excavation in August or September.
