Just how much will a new arena for the Sacramento Kings cost?  The Taylor/ICON group, the arena developers tasked with building an entertainment-and-sports complex in California’s capital city, will formally announce that number at a Sacramento city council meeting later today.  ButSactown Royalty has some of the details: “The final pricetag on the complex is the first question on most folks’ tongue, and it’s $387 million. That includes $241 million in construction costs and, according to the report, $146 million in “soft costs.” The arena would seat right around 19,000 fans for NBA basketball (up from 17,317). At Power Balance Pavilion, there are 30 luxury suites. In the new complex, there would be 74. (!) The additional seating comes mainly in the form of 1,300 new premium and club seats. The other big question answered in the report: when will it be done? The answer: May 2015. So the Kings would bring basketball downtown for the 2015-16 season.”
