A building pursuing the Development Density and Community Connectivity credit is located within a 2 acres community (8,093,m²), in which existing buildings total 90,000 sq. ft (8,361 m²). How large does the building need to be in order to comply with Option 1 of the credit?
The answer is: 30,000 sq. ft. (2,787 m²)
I'm assuming this is so because the minimum density is 60,000, and the building density times the acres would meet this requirement- however, I see no such calculation formula in the reference guide. If someone could explain the concept behind this, I'd be grateful!

Farah,
If I understand this correctly you are pursuing option 1 and you calculated your density radius, the overall average property density within the radius equals 45 000 SF/Acre (=90 000 SF/ 2Acres). So well below the required 60 000SF/Acre.
But the credit requirements require you to account for your own project gross area in this calculations, which you did not.
And you are now wondering how many SF the gross area of your project should come up to in order to reach the minimum density.
Then you are correct: 30 000 SF is the gross area for your project that will be required. leading your average community density to 120 000 SF/2Acres =60 000 SF/Acre
Also, you need to ensure that your project has a density of 60 000 SF/Acre as well.

Hello Charline,
Thanks for your explanation.
Why is 30,000 the gross area required?

Ok, you are targeting an Average property density within the density boundary of 60,000 SF/Acre, right?
You can See the following equation in the reference guide page 29, option 1 STEP 3:
Average property density = (Sum of all property SF) / (Sum of all sites area in acre)
In this equation you need to account for your own project Square footage, this means: (Sum of all property SF) = Existing buildings SF + your project SF
Using the two equations above, this leads to:
Your project SF = [Average property density x (Sum of all sites area in acre)] - Existing buildings SF
Your project SF = [ 60000(SF/acre) x 2 (Acres)] -90000 (SF) = 30000 SF
Hope that helps!!
