SAMPLE CALCULATIONS FOR SINGLE FAMILY RESIDENTIAL, MULTI FAMILY
RESIDENTIAL, AND COMMERCIAL, INDUSTRIAL, AND INSTITUTIONAL
CUSTOMERS
Planting Plans shall be prepared using the following Water Budget Formulas for Single Family
Residential, Multi Family Residential and Commercial, Industrial and Institutional customers:
Maximum Applied Water Allowance (MAWA)
MAWA (in gallons) _ (ETo)(0.62)[(0.6 x LA)]
Where:
MAWA - Maximum Applied Water Allowance (gallons per year)
ETO - Reference Evapotranspiration (inches per year)
0.62 - Conversion Factor (to gallons)
0.6—ET Adiustment Factor (ETAF)
LA - Landscape Area including SLA (square feet)
Example: (55) (0.62)[0.6x4,870)] = 99,640 gallons
Estimated Total Water Use (ETWU)
ETWU (in gallons) _ (ETo)(0.62)[((PFxHA)/IE)] WJ ere:
EAWU—Estimated Annual Water Use
ET„ - Reference Evapotranspiration (inches per year)
0.62 - Conversion Factor
PF - Plant Factor from Water Use Classification of Landscape Species (WUCOLS)
HA - Hvdrozone Area [low and very low water use areas] (square feet)
IE - Irrigation Efficiency (minimum 0.71)
Example: (55) (0.62)[((0.2x4,870/0.71)] = 46,779 gallons
Appendix C
SAMPLE CALCULATIONS FOR COMMERCIAL, INDUSTRIAL, AND
INSTITUTIONAL CUSTOMERS WITH SPECIAL LANDSCAPE AREAS
Planting Plans shall be prepared using the following Water Budget Formulas for Commercial, Industrial
and Institutional customer with Special Landscape Areas (SLA) such as recreational area, area
permanently and solely dedicated to edible plants, and area irrigated with recycled water:
Maximum Applied Water Allowance (MAWA)
MAWA (in gallons) _ (ETo)(0.62)[(0.6 x LA)+(0.4 x SLA)]
Where:
MAWA - Maximum Applied Water Allowance (gallons per year)
ET„ - Reference Evapotranspiration (inches per year)
0.62 - Conversion Factor (to gallons)
0.6—ET Adiustment Factor (ETAF)
LA - Landscape Area including SLA (square feet)
0.4—Additional Water Allowance for SLA
SLA — Special Landscape Area (square feet)
Example: (55) (0.62)[0.6x20,000)+(0.4x2,000)] = 436,480 gallons
Estimated Total Water Use (ETWU)
ETWU (in gallons) _ (ETj(0.62)[((PFx1-lA)/IE) +(0.4 x SLA)]Where:
EAWUEstimated Annual Water Use
ET„ - Reference Evapotranspiration (inches per year)
0.62 - Conversion Factor
PF - Plant Factor from Water Use Classification of Landscape Species (WUCOLS)
HA - Hvdrozone Area flow and very low water use areas] (square feet)
0.4 – Additional Water Allowance for SLA
IE - Irrigation Efficiency (minimum 0.71)
SLA Special Landscape Area (square feet)
Example: (55) (0.62)[((0.2x20,000/0.7I)+(0.4 x 2,000))] = 163,680 gallons
