Parcel-scale Landscape Irrigation Ratios (LIRs)
Landscape Water Use ___________________
Landscape Water NeedLIR =
(estimated from analysis of municipal or water provider meter data)
______________________________________
(estimated from classification of remotely-sensed airborne multispectral imagery, localized reference ETo rates modified by relevant landscape correction factors, and policy assumptions)
(per unit of landscaped
area)
(Identifies Capacity to Conserve Outdoor Water)
LIR less than 1 = EfficientBetween 1 and 2 = AcceptableBetween 2 and 3 = InefficientGreater than 3 = Excessive

Quality of Life
“. . . when I walked past my first lawn,…
I stooped down and touched its cool nap
in awe and unbelief. I think I held my
breath - I had not known that people
anywhere lived with such grace.”
