There is a concern that the soil, because the particle size is much smaller than the gravel, will eventually work its way down through the gravel and you'll begin finding rocks surfacing in your lawn. There's also a concern that the area will drain too quickly and you'll have to water more frequently. If you can remove the gravel prior to sodding you'll eliminate both problems. If not, you might be able to control either problem by putting 6" of topsoil over the gravel (instead of just 4) and tamping it down well to move the soil particles down into the crevices in the gravel. As long as the root system of your turf is well knitted together, the top soil should act as a barrier to the gravel and keep it from surfacing.

Good luck with your project.
