I don't think people really understand how expensive it is to maintain a sand volleyball court. Once again games are not played on the neglected sand pits that you find in front a a dorm. And special sand is used. A quick view on how much one costs is in this link...
http://www.volleyballusa.com/How-To-Bui ... Court.html , remember this is not for a competition court but just a nice one that you build yourself. Notice Sand estimates are not given, but the article does identify why you need special sand and that you need 100 tons of it, sand also requires maintenance especially in colder wetter climates.
As far as the special type of sand (no you can't get this sand at Home Depot or Lowes) competition sand volley ball sand is regulated by the international volleyball association. (feel free to look it up, i was going to find a link to it but ended up clicking a chris chase article and and am now not feeling too well) and yes you must maintain it. It's a pain in the but to maintain a sand volleyball court they need daily maintenance, its like having a pool only sand volleyball courts actually cost more to put in and almost as much if not more to maintain.
Lets not kid ourselves sand volleyball is not a revenue producing sport. it will cost 4 scholarships, travel, coaches, insurance, facility maintenance, for essentially 0 benefit to the school. 4 women's scholarships does not allow you to add any men's programs.
And that brings us to title IX sand volleyball does nothing to assist an AD. In adding programs that could add some revenue and will do nothing but suck up costs. If you want to see girls in swimsuits look to womens water polo... you get more scholarships and you can use the pool that is already on campus. it also gives you more scholarships to work with and is already a confirmed NCAA sport... sand volleyball is a emerging sport there is no guarantee that it will not be dropped by the NCAA, in fact its being dropped is likely. So you build this nice new sand volleyball court. bring in 100 plus tons of sand for... nothing....
That said i'm sure the intramural sports would love it.
