Liberty Property Trust has received its first approvals from Camden's Planning Board for the $1 billion mixed-use project it plans along the Delaware waterfront.

The board granted approval Thursday for Liberty's subdivision plan for 16 waterfront acres and for the development's first office building, a five-story, 219,000-square-foot structure being designed by Robert A.M. Stern, said John Gattuso, Liberty's regional director.

The plans also need to be be approved by the Camden City Council.
