Ben,
We apply a liberal amount of topdressing to cover the crown in an effort to minimize winter desiccation, which is a major concern in our area. However, we never have dumped the sand on during one final topdressing. Rather we start in early October with weekly topdressings instead of our in-season every two week program. We bump the rate up a bit too.
This is done in conjunction with our practice of curtailing mowing at this time. The net effect is by November some of the leaf is showing so the plant is still photosynthesizing and yet the crown is buried. I imagine, in your growing environment, winter is about a month or so behind ours. We are at 6100 feet. So you might start the process in late October/early November??? The fact that you will not have play is a major plus as the abrasion from the foot traffic and sand can be an issue.
This method may also help with the washout issues you seem to be indicating from heavy rains.
