Ideally, you would start a foundation 12" out of the ground at the grounds highest point. Remember to check for drops and slopes such as porches, garages. Exceptions can be made for situations where the ground is sloped as long as the slope will take water away from the slab.
Frost line depth is measured from grade (or lowest surface soil level pursuant to the foundation).
