You can also see the tree distribution. Apple is keen to keep the vast majority of the trees planted exactly where they are. But because it has to bulldoze some to make way for the donut-shaped building, it will plant over a thousand more. HP's campus has 4,200 while Apple wants to bump that number up to 6,000.
Apple's next-generation campus will also have to be secure to prevent protests, intruders, and aliens from landing. The campus will also have a VIP entrance area towards the west of the campus, and include restricted public access. But Apple will probably not be able to escape the fact it will need a great big fence to surround its campus to prevent public access.
The building will have around 300,000 square feet of research facilities. The auditorium, which will be designed for press and analysts to be when Apple announces products and services, will no longer be underground according to the plans. So much for keeping press "in the dark"...
