In a few weeks, we will start building our dream house. During the foundation work, a significant amount of soil excavation will be necessary, mainly clay. Attached is a photo of the borehole profile.
We had the soil tested as part of the geotechnical survey. Almost all components were classified as Z 0 according to LAGA standards. The only exception is the PAH measurement, which was classified as Z1.1 with 1.6 mg/kg (limit for Z 0 = 1 mg/kg).
We have a relatively large plot of about 1400 m² (0.35 acres) and the rear area lies approximately 0.5 m (20 inches) below street level.
The question is whether we need to have the excavated soil disposed of, or if it can be reused on the property, for example, to even out the level in the rear area?
Thank you in advance for your support.

Everything you excavate on your property can be left there and used for landscaping, for example (as long as you comply with the requirements regarding maximum fill height).
It is probably not suitable for backfilling but works great for leveling.
At Z0, disposal costs are also not that high. Your plan makes sense.
Good luck with the construction.
