1.) what size is the high tunnel are you planning?

13.5x24 gothic

2.) what are the "utilities" that are giving you hesitation?

gas, water, electric, sewer - some of which are far more shallow than they should be and unfortunately run about every 6-8' across the entire back yard. Makes bed planning dicey.

2.1) is there an easement that restricts what you might do in the space ? (I have 3 sewers, within 2 easements on our property, one is close to the house and our deck required a variance)

Nothing other than that described above. The yard is small.

2.2) are you just uncomfortable digging near "utilities"?

yes. Also, making the soil more loose adds to the danger of movement so I give them their space. Its an OLD property

and some thoughts:
CALL 811, before you dig! call811.com  They'll come and locate and flag the utility locations. Usually it is done within a few days to a week, it's pretty quick.

They will only do this from street to house hookup. They will not mark between the two structures. Have gone around and around with more than a dozen calls. they show up and then say they can only go to main house hookup.

one could consider the earth-tubes as "another utility" and install along with the others.
the depth does make a difference.

Yeah, at this point I'm thinking they aren't feasible given the restrictions here. Thsnks though.
