The report used several resources to compile the list, including data on PropertyShark.com and tax values as assessed by individual counties.

The players and properties are those most would expect: Apple Inc. takes up two spots in the top-10, and its new Apple Park is, of course, the top spot. Meanwhile Google Inc., which is currently on a massive buying spree across the Valley, takes up three of the top 16 spots.

Notably, Lockheed Martin’s corporate office in Sunnyvale lands at No. 7, even after the company has laid off hundreds of employees in recent years and sold a chunk of its former Sunnyvale campus.

And though some projects that opened after Jan. 1 may not be fully accounted for in the county’s assessment roll, like Apple’s 2.8 million-square-foot Apple Park, the numbers still increased by $30.9 billion year-over-year in the recent report from Stone’s office.

Commercial Cafe’s list includ es the $5 billion circular building, which was named Silicon Valley Business Journal’s Milestone Project of the Year for 2017.

The $30.9 billion growth for the Valley matches the dollar amount that the assessment roll has increased over the past two years and represents six consecutive years of positive office development and leasing. The fact that the number has stayed the same for three years straight also means the market is seeing also some stabilization, Stone said in June, when the report was released.

Whether that number will stay the same again next year remains to be seen, as Nvidia Corp. is aiming to wrap up construction on it its 525,000-square-foot Santa Clara campus by November — just in time for next year’s tax assessment.

Google has started construction on its 595,000-square-foot Charleston East campus and restarted work on its Bay View development, which is also in Mountain View, though it sits on federal land owned by NASA.

A potential 8 million-square-foot San Jose development by the search giant could also up future tax rolls in the county when or if it is completed and employees begin moving in, which would likely be years from now.
