Don't know if a local tax would be an option. UL is a state entity and I dust don't know that the State would allow us to have a local vote to fund something for a local university.
For example, the gas taxes we pay at the pump are federal and state. Programmatically, these revenues are SUPPOSED to go to road construction/maintenance (I think they also pay for State Police - remember, I said supposed to go to contruction). Lafayette Parish is a donor Parish when you look at the State revenues produced by this tax. But we get NOWHERE close to a return on the construction dollars in this Parish. Basically, we contribute way more than a dollar in gas taxes to the state and get way less than a dollar in construction projects. Desoto Parish contributes way less in gas taxes to the State but they get way more than a dollar in construction projects.
I think the possibility of having a local option gas tax for Lafayette Parish has been discussed but the State has never been willing to consider it. Pretty sure it would take an act of the Legislature but it hasn't happened.
You can probably anticipate the same problem with a local option Higher Education Tax.
I don't mean to come across as thinking this is a bad idea. On the contrary, I think its a great idea. Not sure how much a 1% sales tax would generate. From what we're hearing about the proposed LCG Parks and Rec property tax, I think a 5 mill property tax would generate $6 million. As I said before, I think this would another incredible example of community commitment to the program, which would should make the program more attractive to bigger conferences.
