Correct Answer: B
To meet the minimum density requirements for the Neighborhood Pattern and Design Prerequisite on Compact Development, the project needs to achieve a certain level of residential and non-residential density.
Given that the project currently has 55 townhomes on 9 acres of buildable land and 44,000 ft² (4,088 m²) of commercial space on 87,120 ft² (9,094 m²) of buildable land, adding eight dwelling units would help the project meet the minimum density requirements. This would increase the residential density, helping to achieve the threshold needed for LEED certification under this prerequisite, which encourages more compact, efficient land use.
