15-0202 v2.1/Definitions and Calculations (Part IV)

QUESTION

Please provide further clarification on this post and attached pdf titled 11-0710-Urban-Agriculture-diagrams.pdf.

1. On the pdf- Should the percentage listed on the diagram for FAR< .05 actually be 80%? It appears that it incorrectly lists 5%.

2. Clarification on the last part of the post and the inclusion and/or definition of the area of disturbance in the % of food production required:

from post: "Yes, since the percentage of urban agriculture required per project is relative to the building's FAR, the other areas of disturbance are not factored into the equation. However, these features will likely influence the type(s) and placement of urban agriculture on your project site."

Could you clarify if the "other areas of disturbance" that is being referred to is different than that included in the project area calculation?

Since the diagram shows and lists a percentage of the project area (defined in other posts to include the property boundary, or in campus setting 30 feet beyond areas of disturbance as well as the footprint of the building/infrastructure and modified land use) to be used for food production, then areas of disturbance would factor in to the percentage of urban agriculture required since they are part of the square footage calculation of the project area.

For example, if a building gross area is 7,000 sf and the project area is 100,000sf (area of disturbance with the 30 ft offset or the property boundary), the FAR is .07. According to the diagrams, this requires 50% of 100,000sf or 50,000sf of the site to be used for food production. Is this correct?

ANSWER 

Part IV Yes, your calculation is correct. Our interpretation of the original question was to distinguish "building" from "landscape" area in the FAR calculation. FAR = Gross Building Area / Total Project Area The landscape and other areas of disturbance do not factor into the nominator of the equation. Instead, landscape and other areas of disturbance contribute to the denominator and are included in the Total Project Area. Here is a hypothetical example that includes information about all variables in your question: total project area: 5,000 square meters (0.5 hectare) gross building area: 8,000 sq m (4 levels at 2,000 sq m each. building footprint is 2,000 sq m) landscape area: 1,000 sq m ""other area of disturbance"" area, eg roads, paths, trenches, etc.: 1,000 sq m The FAR would be the ratio: 8,000/5,000 = 1.6 (It would be incorrect to do this: [8,000+1,000+1,000]/5,000 = 10,000/5,000 = 2.0) Thank you for pointing out the typo on the diagram sheet; it has been corrected.
