Why don’t you start with 4S Ranch, starting from the lowest price homes on up to the 3000 sf ones? Compare their lot sizes to neighboring 1970’s Rancho Bernardo homes.
Then order the plats on Otay Ranch (Chula Vista) and compare lot sizes of its tracts to neighboring Castle Park (91911), now 40-55 years old.
I believe the average lot size difference to be about 2500 sf.
As an example, these two areas were built out since 2000.
A cheaper, easier way is to just look at the satellite pics on the newer and older tracts online on Bing or Google maps and compare them. The level of density is shocking on the newer tracts, often built out in the middle of nowhere.
