The Warriors have rejected an offer from the San Francisco Giants to build an arena on land adjacent to AT&T Park. The franchise is instead working independently on arena plans on the waterfront of Piers 30 and 32 in San Francisco.

"This is an ownership group that is pretty bold and visionary, and the prospect of doing something grand is really alluring to them," said one source familiar with the Warriors' plans.

The Warriors' lease at Oracle Arena in Oakland expires at the end of the 16-17 NBA season.

Piers 30 and 32 are closer to the Bay Bridge and downtown San Francisco, which make the site more appealing for the Warriors.
