A new five-story building with a 30,000 ft? (2 800 m2) footprint is being designed on a previously disturbed 100,000 ft? (9 290 m2) site. The remaining on-grade surface will be 35,000 ft? (3 250 m2) of asphalt parking, and 35,000 ft (3 250 m) of native vegetated open space. To achieve a point for exemplary performance under Option 1 of Sustainable Sites Credit, Site Development - Protect or Restore Habitat, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of Calculator 12,500 ft? (1 160 m) B 15,000 ft? (1 400 m}) 25,000 ft (2 300 m) D 35,000 ft (3 250 m2)
