Plans for Lincoln Yards are being revealed not long after the city announced major zoning changes for a swath of land near the river that was long limited to manufacturing uses. In anticipation of the potential changes, Sterling Bay has invested hundreds of millions of dollars on properties in the area, including $140 million for the 28-acre Finkl site and a pending $104.7 million for a city-owned vehicle maintenance facility just across the river from the Finkl site.
