San Diego Chargers officials investigating viral video showing alleged sexual act on field

<p>Let&#39;s say a sports stadium, arena or complex needs renovations. Or maybe a new structure altogether.&nbsp;</p><p>There are typically a few ways to go about financing the construction: public funding, private funding or a combination of the two.&nbsp;</p><p>When the United States Tennis Association decided rain was postponing too many matches at the U.S. Open year after year, it chose to build a $150 million retractable roof over its main stadium using private funding. (Video via&nbsp;<a href="https://www.youtube.com/watch?v=0PkGxbncYAo" target="_blank">The Wall Street Journal</a>)&nbsp;</p><p>The USTA used bank bonds to finance the project, and plans to pay those bonds back through ticketing and broadcasting revenue. (Video via&nbsp;<a href="https://www.youtube.com/watch?v=5qjZYR9sYfQ" target="_blank">US Open Tennis Championship</a>)</p><p>Public funding, which is when taxpayers cover the tab, tends to be a much more controversial model.&nbsp;</p><p>There&#39;s the belief that new or renovated stadiums could bring in more business and benefit local economies. Wisconsin Gov. Scott Walker said this about a $500 million stadium for the NBA&#39;s Milwaukee Bucks roughly half of which would be paid for using taxpayer money.&nbsp;</p><p>&quot;This is all based on growth. This is the ultimate free market, fiscally conservative approach going forward,&quot;&nbsp;<a href="https://www.youtube.com/watch?v=iVZpvRGShrM" target="_blank">Walker said</a>.&nbsp;</p><p>But a number of studies refute that, suggesting many stadiums have no positive economic benefit.</p><p>That probably stings even worse if a team isn&#39;t that good like the NHL&#39;s Arizona Coyotes</p><p>In the NFL, a lot of stadiums have been built in recent years. Using numbers from a sports research and consulting firm,&nbsp;<a href="http://money.cnn.com/2015/01/30/news/companies/nfl-taxpayers/" target="_blank">CNN reported</a>, &quot;Twenty new NFL stadiums have opened since 1997 with the help of $4.7 billion in taxpayer funds.&quot;&nbsp;</p><p>At the moment, lawmakers have proposed using taxpayer money to build new NFL stadiums in at least three cities: St. Louis, Missouri; San Diego, California; and Oakland, California.&nbsp;</p><p>For those cities, the choice is this: find the money or your team finds a new home.&nbsp;</p><p><i>This video includes Getty Images and music by Birocratic /</i>&nbsp;<i>CC BY ND 3.0.</i></p>
