Will do, I'll get plenty of photos and explanations. The area is quite dry and I worried about the soils drying out over time and losing efficiency. bad contact, etc.

I'll backfill the coils with 2' and compact, grade level and put in a grid of 4" drain pipe on 6' centers to a header. I'll connect the yard drain and downspout drains to that so we can keep things nice and moist without wasting water.

I'll be regrading the lot, and digging for the addition/garage.
