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 Fill in these blue sections below.Some
11 Irrigation Water Budget=[(ETo x Plant Factor)-Re]x Irrigated Area+Irrigation Efficiency x 0.623 columns have drop down menus to
12 assist you in filling out.The formulas
13 Where:
14 ETo=Reference Evapotranspiration in inches/season(May-Sept.) Reference Evapotranspiration will calculate the site average annual
15 Re=Effective Precipitation in inches/season(May-Sept.) 27.4 inches/year water use.Once completed you may
16 Irrigated Area=Hydrozone Area in Square Feet 17.1 gallons/square foot either attach this document to the
17 submital packet or insert it into the
18 Hydrozones Efficiency Effective Precipitation design set.
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%
25 Drip 90%
