Default calculate it..

A decent approximation could be obtained by determining the perimeter of every island and dividing each by an average lot frontage to arrive at number of lots per island. The number of inhabitable islands is known and the perimeter can be estimated if there is an acreage known for each of them.

Finally reduce the count by factoring a guess for undeveloped lots (20%?). Errors in these kind of estimates tend to cancel and a surprisingly good result can be obtained.

I'll leave the heavy lifting for someone else to do...!
