State officials said today they'll spend $47 million in federal stimulus funds and state bonds for a new garage at Wonderland station on the Blue Line.

At a ceremony there today, Gov. Patrick and other officials said the new nine-story, 1,900-space garage will be the first step in construction of Waterfront Square, a proposed development of 902 residential units, office and retail space and a hotel.

Roughly $23 million of the garage cost wll come from the feds, the rest from an MBTA bond that will be repaid through revenue from the parking lot.
