(2) In this next hypothetical example, the landscape project in Fresno, CA has the same ETovalue of 51.1 inches and a total landscape area of 50,000 square feet. Within the 50,000square foot project, there is now a 2,000 square foot area planted with edible plants. This2,000 square foot area is considered to be a Special Landscape Area.MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]MAWA = (51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 2,000 square feet)]= 31.68 x [35,000 + 600] gallons per year= 31.68 x 35,600 gallons per year=1,127,808 gallons per year or 1,508 hundred-cubic-feet per year(d) Estimated Total Water Use.The Estimated Total Water Use shall be calculated using the equation below. The sum of theEstimated Total Water Use calculated for all hydrozones shall not exceed MAWA.ETWU = (ETo)(0.62) ( PE x HA + SLAWhere:ETWU = Estimated Total Water Use per year (gallons)ETo = Reference Evapotranspiration (inches)PF = Plant Factor from WUCOLS (see Section 491)HA = Hydrozone Area [high, medium, and low water use areas] (square feet)SLA = Special Landscape Area (square feet)0.62 = Conversion FactorIE = Irrigation Efficiency (minimum 0.71)(1) Example ETWU calculation: landscape area is 50,000 square feet; plant water use type,plant factor, and hydrozone area are shown in the table below. The ETo value is 51.1 inchesper year. There are no Special Landscape Areas (recreational area, area permanently andsolely dedicated to edible plants, and area irrigated with recycled water) in this example.Plant HydrozonePlant Water Factor Area (HA) PF x HAHydrozone Use Type(s) (PF)* (square feet) (square feet)1 High 0.8 7,000 5,6002 High 0.7 10,000 7,0003 Medium 0.5 16,000 8,0004 Low 0.3 7,000 2,1005 Low 0.2 10,000 2,000*Plant Factor from WUCOLSSum 24,700ETWU = ( 51.1)(0.62) (24 700' +00.71= 1,102,116 gallons per yearCompare ETWU with MAWA: For this example MAWA = (51.1) (0.62) [(0.7 x 50,000) + (0.3 x0)] = 1,108,870 gallons per year. The ETWU (1,102,116 gallons per year) is less than MAWA(1,108,870 gallons per year). In this example, the water budget complies with the MAWA.4010
(2) Example ETWU calculation: total landscape area is 50,000 square feet, 2,000 square feetof which is planted with edible plants. The edible plant area is considered a Special LandscapeArea (SLA). The reference evapotranspiration value is 51.1 inches per year. The plant type,plant factor, and hydrozone area are shown in the table below.HydrozonePlantFactor(PF)*HydrozoneArea (HA)(squarefeet)Plant WaterUse Type(s)1 High 0.8 7,000 5,6002 High 0.7 9,000 6,3003 Medium 0.5 15,000 7,5004 Low 0.3 7,000 2,1005 Low 0.2 10,000 2,000PF x HA(square feet)Sum 23,5006 SLA 1.0 2,000 2,000Factor from WUCOLS*PlantETWU = (51.1)(0.64 23 '500 + 2,0000.71= (31.68) (33,099 + 2,000)= 1,111,936 gallons per yearCompare ETWU with MAWA. For this example:MAWA = (51.1) (0.62) [(0.7 x 50,000) + (0.3 x 2,000)]= 31.68 x [35,000 + 600]= 31.68 x 35,600=1,127,808 gallons per yearThe ETWU (1,111,936 gallons per year) is less than MAWA (1,127,808 gallons per year). Forthis example, the water budget complies with the MAWA.Note: Authority Cited: Section 65595, Government Code.
