Filipe it is in North Carolina so definitely soil is optimal here for flowers, trees etc.

Just moved to the area and I am looking for buy a duplex around the Alphareta, Marietta, Sandy Springs area.

Here are the key items you need to address before the land is purchased;You will need PERC testing to determine if the land/soil can support septic and absorb water.

My STR tenants that were doing soil remediation and underground fiber optic network installation went home for 2 weeks because they couldn't work.

Coastal stuff built in the 1960s had none of the earthquake and geotechnical requirements we have today, and parts of the coastal areas present challenges (I'm doing a project about 4 blocks from the water now that happens to be in a liquifaction zone, necessitating plenty of soils work, even for a small addition).I guess my only other comment is the use of the "construction crew" ... that's no small feat at the moment. 

Maybe I will have to raise approx 8-10' ft I do not know how easy is it to fill the soil and its impact on new construction layout etc.I would like to get some insights from members based on their experience.Is this just a NO NO.

If the soil is good and you want to place houses there, I would approach the power company and see if they will move the lines. 

Best not to get too greedy and potentially soil future business.

Soils below the uncontrolled fill were moisture sensitive, highly compressive soils down to refusal at depths of 45-67 feet.

Nope I have not heard that, tho I only do commercial... the sand is shifting for the banks right now.
