[EnergyPlus_Support] modeling of partial earth berm

I'm modeling a school that has a small earth berm around most of its
perimeter. The berm is 1m high at the outside wall, and slopes down at
about 15° until it reaches grade about 3.75m from the wall. I have two
ideas as to how to best model this:

1. Create a "soil" material and that has a thickness of 1.875m
(3.5m/2) so that when applied onto a surface that is 1m high, it will
have the same volume per unit wall-length as the berm. Use this as the
outermost material in the construction for a surface that covers the
bottom 1m of the exterior wall.

2. Use the basement pre-processor and model the building as basically
sitting in a 1m deep basement. 

Which of these approaches should I use (I'm leaning towards #1...)?
Should I even bother modeling this? Any assistance anyone could give
me would be greatly appreciated.

Thanks,

Josh
