Said map amendment would add the designation “D,” indicating a Planned Development Area overlay to approximately +/- 104,440 square feet (2.4 acres) of land bounded generally by Boylston Street to the north, Kilmarnock Street to the east, Private Alley #932 and Peterborough Street to the south, and Park Drive to the west. Said development plan would allow for approximately 553,000 square feet of development. The building fronting on Boylston Street will include 531,000 sf of office and R&D space, loading and other building service uses, and approximately 17,000 sf of engaging ground floor retail and/or restaurant space. An approximately 5,000 sf civic building is proposed, which will be programmed in response to community needs and could serve as a Boston Public Library neighborhood branch. The project will also include below grade parking to support approximately 246 net new spaces. Additionally, approximately one-half acre of new publicly accessible open space along Park Drive will be created
