All I did last night was look at this again and measured how much height I have. Duh! It is only 9 scale feet from the stream bed to the the top of the roadbed. I believe number 3 would be the best choice for this application. Everything else would be more appropriate for a higher fill.
On another note; I am off work and nothing else is pressing, so I am planning to go over to my mother-in-law's and start taking that workbench apart that will provide a lot of wood and even Homasote for my new layout. I'll keep my fingers crossed that nothing else happens and I actually get this done.
