2.1 ASSESSMENT PER SPP
Potential Fireline Intensity (Equation 1) per SPP 2016 Technical Manual

Equation 1. PFI = 0.62 PFL2 *FFDI*EXP (0.069 *slope degrees)

PFI       Potential Fireline Intensity

PFL       Potential Fuel Load             per Redi-Portal data

FFDI      20 year FFDI site specific      47

Area 1

VHC 41.4      Low grass or tree cover in built up areas
VHC 41.4      Potential Fuel Load     3t/ha
Slope Degrees                         20

Equation 1. PFI = 0.62 x3 2 * 47* EXP (0.069 *2) =
