Expanding upon @ShaneH 's suggestion, USAWS could even promise to host X number of national level events at any sites developed under that program. Sorta the way the NFL promises Super Bowls for cities that build new stadiums. This could be a very big Economic Development play as hundreds of competitors need hundreds of hotel rooms, meals, etc.
The first step would be to quantify the economic impact Okeeheelee has had for Palm Beach County. Not just when they host Nationals but from all the ski-related tourism that it generates. There are a number of firms that could do that.
