I think it's Bermuda. It's common in kc metro, including PV. Looks just like mine, too. Don't think buffalo is as prevalent.
NK is right, don't need to water Bermuda very much. In fact, I've read it's bad to water any grass a lot in spring time, as it impedes the grass's ability to tolerate dryer, hotter summer months.
Bermuda isn't as "pretty" as fescue, but it is hardier and, once it greens, will stay green through the summer.
My advice, just leave it alone. Fertilize in mid May and mow it. That's about it.
