Any spills or moisture will penetrate/wick through the seams and sit underneath the flooring...Plus LVP looks crappy and cheap, like you'd use in an apartment.

Anybody (me or a later buyer) who built on the lot would risk losing it if a claimant won owner to the land underneath. 

The soil composition had to be tested and cleared before development could begin.

You have to mine 240 tons of soil for the rare minerals used in Electric batteries.  

We would go to soil engineers or others.

Going over maps of known repairs with contractors showed that there were a few houses where people tried to have piers installed and ran out of money before hitting stable soil, others in the hyper local area did have to go to 100+ ft.  

.🔹 Step 9 & 10: Engineering & DrainageNot the most exciting part, but if your property needs engineering reports (like soil testing or drainage fixes), get it done now.

Phase 1 is an initial assessment, more focussed on document research while Phase 2 is where they actually take soil samples etc. 3.

For example things such as how to handle certain soil conditions, working with certain agencies, specific water quality requirements (which you mentioned).
