It looks to me maybe y'all skeptics to above did not take in the posted "times of israel" article and it's video on the unique properties of this tiny site. Or you were making plausible generalities for generic sites or vast areas in general. My observations had been:
The compactness of this site, dense with architecture. it might fit in footprint of a modern Walmart store and have had loads of artifacts, recently removed by archeologists.
The elevated nature of the site, which appears to comprise the upper half of a 500ish foot hill surrounded by undeveloped apron slope. The downhill foot of the apron was the discovery zone seen, I think, in the last second of their video.
The soil looks like classic impermeable dry zone stuff that promotes flash floods, which Israel did experience this winter. Hundred year floods may trap material ground off top of hill towards the foot.
