Upon the news of a possible relocation, Sacramento Kings launched a grassroots effort with pledges of over $800,000 to go to a new arena. This and other grassroots efforts, along with Mayor Kevin Johnson's presentation to the NBA Board of Governors, convinced the NBA to delay any relocation authorization for one year. Within this one year time frame (deadline: March 2012) a completed arena plan, with funding, must be in place. Plans were approved by the City Council in March 2012 and construction for the Kings' new arena, the Golden 1 Center, began on October 29, 2014 and it was completed prior to the start of the 2016-17 NBA Season.
