Mike,
It would an extreme slope adjacent to a green that would allow that to happen, and that would only be in a very hard rainfall event. A super can handle that situation easily. Drop spreaders and hand irrigation takes the unknowns out of the equation.
At Landfall Club in Wimington, NC, we had bermudagrass fairways surrounded by centipedegrass roughs. As you know, these grasses are exact opposites in their nitrogen requirements. The super had us use walk behind drop spreaders to fertilize the first 6 feet of the border of those two grasses. I was expensive (labor) but it worked.
I wouldn't avoid a lay of the land green because of this issue. Drainage is a much bigger issue, in my opinion.
