In a mixed use development on a 2.0 hectare site with 2.0 FAR, the ratio of residential to commercial floor area is 3:2

Q. In a mixed use development on a 2.0 hectare site with 2.0 FAR, the ratio of residential to commercial floor area is 3:2. The minimum parking (in ECS) needed per 100 sqm of residential and commercial floor area is 1.0 and 1.25 respectively. Considering full FAR utilization, the total parking requirement is__________ECS.

Ans: 440 to 440

Sol:

Site Area = 2.0 hectare = 20,000 sq.m. Maximum
FAR = 2.0. Thus, Maximum Built-up Area = 40,000 sq.m.
It is given that, Ratio of residential: commercial floor area = 3: 2
Thus, Area for residential as per 3: 2 ratio = 24,000 sq.m. & Area for commercial as per 3: 2 ratio = 16,000 sq.m.
Minimum parking (in ECS) needed per 100 sq.m, of residential area = 1.
Thus, ECS required for 24,000 sq.m, of residential area = 240
Minimum parking (in ECS) needed per 100 sq.m, of commercial area = 1.25.
Thus, ECS required for 16,000 sq.m, of commercial area = 200
Thus, total ECS required for 40,000 sq.m, of maximum built-up area = 240 + 200 = 440
