From a Mercury News article by Thy Vo, August 22, 2019: Under state law, Sand Hill Property Co., the owner and developer of Vallco Shopping Mall, has the right to build 2,402 apartment units — half of them below market rate — plus 1.8 million square feet of office space, 400,000 square feet of retail, and a 30-acre rooftop park, all as approved by the Cupertino City Council. But if the current plan gets tossed, whatever project replaces it won’t feature any office space. The City Council on Aug. 21 approved a general plan amendment that eliminates a 2-million-square-foot allocation for office space [on the site] and imposes a 60-foot height limit on buildings at the vacant shopping mall.
