CUPERTINO  (AP) — Officials in the Silicon Valley city of Cupertino endorsed Apple Inc.'s plans for a new, 176-acre campus in the city. The plan now goes to the City Council for approval. Here are some of its highlights:

SPACESHIP DESIGN: Former Apple CEO Steve Jobs likened the estimated $5 billion campus to a spaceship. The main building would be shaped like a disc and have more than 2.8 million square feet of space. The campus would also have a fitness center and a 1,000-seat auditorium. It is expected to be completed in 2016.

APPLE WORKFORCE: Apple has said it expects to increase its Silicon Valley workforce by nearly 50 percent during the next three years, adding 7,400 more workers in Cupertino. Apple now employs about 16,000 people in and around what has been the company's hometown for most of its 37-year history.

ENVIRONMENTAL CONCERNS: An environmental review has found the headquarters will have significant traffic impacts along a nearby freeway and roads. Apple says it aims to get more than one-third of its employees to work on its charter bus program or some other form of transportation other than personal vehicles. Currently, 28 percent of Apple employees travel to work using transportation other than their own car.
