Very high density in a rapidly developing area

Hi, Our project is a campus filling a city block across the street from the premier sports stadium, a huge entertainment complex and a convention center in major US city. Not surprisingly, everything in the neighborhood is being developed to a similar density (over 300,000 SF/Acre). However, at the moment, none of the new projects are completed, and Google Earth shows a lot of mud and surface parking. We would like to earn SSc2 as a campus credit and go for exemplary performance as well. 2 Questions: For projects that are approximately on our time line, it seems legitimate to use the density of the projects as they will be when completed, not as vacant. Correct? 2. Due to the size of the project, the density radius for the basic credit itself is 1340 ft; for EP it's over 1900 ft. This means we have literally several hundred individual properties to account for, and it is really burning hours (without making our planet any healthier). Is it possible to go by block, where there is pretty much a uniform number of stories; perhaps subtracting 20% for alleys? There is an average of 8-12 buildings per bock on the already-developed tracts, so that would make our work much faster. Thanks! .
