I am working on a retail store project in downtown Houston. The project is in the mall and I am looking for some help with this credit.

I am planning to use a commercial building for this calculation. I am using this data source:https://landgrid.com/us/tx/harris/houston#p=/us/tx/harris/houston/1120453

There are 3 different values I am seeing one is Actual/Base area which 1698931 sqft, Calculate Acres is 6.67 and Calculated Parcel is 290,686 sqft.

How shall I calculate a combined density? Is it correct for me to divide 1698931 sqft by 6.67 acres?

I also do not see any residential area in 400-meter radius so can I still achieve this credit just using this building?
