LOS ANGELES, CA (Catholic Online) - According to plans, the campus, in the shape of a circular "doughnut," will cover 2.8 million square feet and have its own power plant inside its massive design.

The campus will be covered in solar panels and house up to 13,000 people daily in addition to housing 6,000 trees.

Scheduled to be completed in 2015, Apple's new headquarters may be one of co-founder Steve Jobs' final, longest-lasting legacies.

In a letter sent out to residents, the four-story building will be a research facility. The new building will not replace the existing campus on 1 Infinite Loop. The campus will not be open to the public, so there will be no museum or corporate store.

The structure will contain an auditorium that seats 1,000 and will be used for special events like product unveilings, though.

Apple CEO Peter Oppenheimer says the company plans to break ground on the site as soon as Cupertino gives its approval, expected later this year.

Neighbors are invited to send Apple a letter or go to the city's Web site to express any concerns.

Cupertino is a suburban city of roughly 58,000 people. The chief concerns of local residents have focused on additional traffic and environmental impact, both of which Apple says it is addressing in the design of the campus, expected to receive Leadership in Energy and Environmental Design certification as an environmentally friendly project.

The new campus was one of the last major initiatives for Jobs, who passed away last year.

When Hewlett Packard abandoned its Cupertino campus in 2010, Jobs quietly arranged to buy the site, according to Walter Isaacson's biography, "Steve Jobs."

"I want to leave a signature campus that expresses the values of the company for generations," Jobs told Isaacson.

A team of 50 architects was hired with Jobs being intimately involved in the details, according to the book.

Much of the campus sits on the former site of an apricot orchard, and Jobs required that 80 percent of the campus be natural, with more than 6,000 trees. Apple hopes to raze 26 buildings on the site to make room for the "spaceship," which will be surrounded by grass and trees.
