EDT,

I can�t comment specifically on your soil, however, I would suggest (in general) I have had good success with the advice of local government agencies. They have the relevant information/experience you need for those types of decisions.

Question: If you plan to dig 20', why not dig a few 20' holes and test the soil to be positive of the soil content? That would be a cheap insurance policy before starting major work...just a thought.

Did you have any discussions about watershed for your site?

(BTW - good thinking so far)
