The Boston Preparatory Charter Public School has filed plans with the BRA to move from rented space at Most Precious Blood in Cleary Square to a new building at 875 River St., across from the PriceRite supermarket.
The school says the 2.2-acre parcel, now home to a parking lot and some trees, would let it build a state-of-the-art 48,000-square-foot school for its 400 students in grade 6-12. The proposal calls for 56 parking spaces for staff.
The school had originally hoped to buy a parcel next to the Mattapan Square trolley station, but the MBTA backed out of the deal after local elected officials said they wanted something more residential or commercial for that space.
