Given these parameters, what are the surrounding residential and nonresidential densities when attempting to achieve Location and Transportation Credit, Surrounding Density and Diverse Uses?

The total land area within a 1/4 mi. (0.40 km) radius of a project boundary consists of 130 acres (53 hectares) and has a residential to nonresidential ratio of 60:40. Within this same total land area, there are 780 dwelling units and1,600,000 ft2 (148 645 m2) of nonresidential building space.

Given these parameters, what are the surrounding residential and nonresidential densities when attempting to achieve Location and Transportation Credit, Surrounding Density and Diverse Uses?
A . 10 dwelling units per acre (24 dwelling units per hectare) and a Floor Area Ratio (FAR) of 0.47
B . 10 dwelling units per acre (24 dwelling units per hectare) and a FAR of 0.70
C . 13 dwelling units per acre (32 dwelling units per hectare) and a FAR of 0.47
D . 15 dwelling units per acre (36 dwelling units per hectare) and a FAR of 0.70

Answer: C

Explanation:

The surrounding residential density is calculated by dividing the total number of dwelling units by the total residential land area. In this case, it would be 780 dwelling units divided by 60% of 130 acres, which equals approximately 13 dwelling units per acre (or 32 dwelling units per hectare).

The nonresidential density, or Floor Area Ratio (FAR), is calculated by dividing the total nonresidential building floor area by the total nonresidential land area. In this case, it would be 1,600,000 ft² divided by 40% of 130 acres, which equals a FAR of approximately 0.47.

These calculations are used when attempting to achieve the Location and Transportation Credit, Surrounding Density and Diverse Uses, under the LEED AP BD+C V4 rating system.
