Narrative:
Descending into rhv airport in moderate to occasional severe turbulence, couldn't reach rhv tower due to radio congestion. Could not stay clear of rhv class D airspace due to turbulence. I didn't get in contact with rhv tower until after I was well within the class D airspace. Again, I couldn't stay clear of class D airspace because staying clear would keep me on leeward side of mission peak where the turbulence was.
