Just had my bulkhead replaced, most of my backyard had washed away. Someone recommended that i put down sand first then clay. Would you recommend something different? I have no clue.
Doesn't sound right to me. If the sand is closer to the water, is will fill with water and swell, and dry up when the water is low and put holes in your yard.

I would pack it with clay on the bottom, and put regular dirt the top 12 inches. The clay will pack tight and hold the bulkhead from moving any.

I am not a pro though, it just seems that you couldn't pack clay on top of sand, and grass doesn't really favor clay

This just sounds wrong. I'm no civil engineer, but I don't think silicate expands when wet. Clay, on the other hand, definitely has some expansion issues.
