In-situ FSI = 2.0× this area (Reg 11, Sr. 11a)

DP reservation area (sq m)

Open space & amenity (UDCPR Reg 3.4 & 3.5)

Gross plot area = Total land area as per city survey / revenue records.
Net plot area (Reg 3.9) = Gross minus amenity space (Reg 3.5) and DP/RP road proposals. FSI — basic, premium and TDR — is always computed on net plot area.
ROS (Reg 3.4.1) = 10% of gross plot for plots ≥ 0.4 Ha — a physical reservation within the net plot. Not deducted for FSI. FSI still applies on full net plot.
Amenity space (Reg 3.5.1) = 5% of gross for plots ≥ 2 Ha — deducted from gross to get net plot. FSI not applied on this portion. Owner compensated via TDR or in-situ FSI.
Inclusive Housing (Reg 3.8) = 20% of basic FSI as EWS/LIG tenements — FREE of FSI in large MCs on plots ≥ 4,000 sq m.
