Certainly, the CFD would have to tap into revenue from businesses year-round, not just on the days of Coyotes games.
In that regard, I continue to wonder about the business case for this. According to an article in The Arizona Republic, the sales-tax revenue from the Westgate businesses was about $13 million (
http://www.azcentral.com/community/glendale/articles/2010/08/11/20100811glendale-sports-debt.html). Raising sales taxes for that district would have to make it worthwhile for the local businesses. So how much of their business is generated by Coyotes fans? I begin with the simplifying, but optimistic estimate that 7500 Coyotes fans (i.e. more than 50%) patronize Westgate businesses in connection with each and every Coyotes game. If each of them spend $50 ($200 for a family of 4) on local businesses, then the total revenue for the year would be about $15 million. I have seen it noted that the Glendale sales tax rate is about 3%, in which case the total tax revenue from Coyotes fans on game days would be about $450,000. This represents about 3% of the total sales tax revenues that Glendale reports that they receive from the arena and surrounding Westgate businesses.
This suggests to me that although important, Coyotes fans per se must represent a rather small proportion of the revenue generated at Westgate businesses. So, the question for those businesses must be how much they are willing to increase their cost structure to support the Coyotes operation.
I welcome comments on this analysis, which is admittedly simplistic. Particularly, I would be interested to know whether others have any estimates about the proportion of Westgate's total business revenue is driven by Coyotes' fans.
