hi Shore Thing,
On our island building, we don't have a dug foundation, but rather poured concrete piers with the regular old ground underneath and the house propped up above the ground. As far as runoff is concerned, rainwater is free to travel under our place and be absorbed into the ground. Does this type of structure change the calculation at all, or is it still considered the same as a dug foundation? And, if an outbuilding was added at a later date of similar elevated construction, would that be an easier process?
Thanks,
Lakershaker
