8 CALCULATING GALLONS OF WATER NEEDED BY PLANT CATEGORY AND IRRIGATION TYPE Directions for Use
9 The specific irrigation water needs of each hydrozone in the design should be determined using the following formula and factors:
10
11 Irrigation Water Budget=[(ETo x Plant Factor)-Re]x Irrigated Area+Irrigation Efficiency x 0.623 Fill in these blue sections below.Some
12 columns have drop down menus to assist
1 3 Where: you in filling out.The formulas will
14 ETo=Reference Evapotranspiration in inches/season(May-Sept.) Reference Evapotranspiration calculate the site average annual water
15 Re=Effective Precipitation in inches/season(May-Sept.) 27.4 inches/year use.Once completed you may either
16 Irrigated Area=Hydrozone Area in Square Feet 17.1 gallons/square foot attach this document to the submital
17 packet or insert it into the design set.
18 Hydrozones Efficiency Effective Precipitation
19 _ Water Use Category Plant Factor Code 6.8 inches/year
20 Cool Season Turf 0.90 VH 4.2 gallons/square foot
21 High 0.80 H
22 Medium 0.65 M Irrigation Efficiency
23 Low 0.40 L Irrigation Method Default Efficiency _
24 Very Low 0.25 VL Overhead 75%
