What is a consolidated site

There really isn't a category of integrated sites on the standard, it's the questioner who misunderstands what A is saying.

Integrated land is the opposite of a single site. When a site is integrated, my understanding is that it is necessary to arrange different functions on the site, such as residential land, commercial services, parking lots or transportation facilities, and even cultural services such as hospitals and elementary school, but it is required that these sites do not overlap spatially.

Single site, for example, the entire site is all a class of industrial site, and another example of residential land, this site is all residential neighborhoods, and so on.
