When the U.S. Geological Survey at 345 Middlefield Road hit the market in April, 2025, it was 98% vacant before being acquired by Presidio Bay Ventures for $137,000,006.

In an article published by the San Francisco Standard, Presidio Bay last week submitted a proposal to Menlo Park’s Planning Division detailing a comprehensive transformation of the 412,663-square-foot former government office complex. 

According to the Standard, the plan calls for tearing down 16 of the 17 structures to make way for three apartment buildings with a total of 670 units; 740,000 square feet of office space; 40,000 square feet of retail; and a 15,000-square-foot child-care facility. In between would be three acres of public open space. At the corner of the public lawn, the developer plans to build a two-story building, The Pavilion, which will be used to host community events and programmed activities.
