WATER EFFICIENT LANDSCAPING STANDARDS AND ORDINANCE
WATER EFFICIENT LANDSCAPE WORKSHEET -- WATER BUDGET ANALYSIS
Note: Project Applicant must complete this worksheet as it is a required element of the Landscape & Irrigation Documentation Package.
SECTION A. GALLONS OF WATER NEEDED BY PLANT CATEGORY AND IRRIGATION TYPE:
The specific irrigation water needs of each hydrozone in the design should be determined using the following formula and factors:
Irrigation Water Budget = [(ETo x Plant Factor) - Re] x Irrigated Area + Irrigation Efficiency x 0.623
Where:
ETo = Reference Evapotranspiration = 27.4 inches/season (May through September)
Re = Effective Precipitation = 6.8 inches/season (May through September)
Irrigated Area = Hydrozone Area in Square Feet
Water Use Category Plant Factor Irrigation Method Default Efficiency
Cool Season Turf 0.90 Overhead 75%
High 0.80 Drip 90%
Medium 0.65
Low 0.40
Very Low 0.25
SECTION B. HYDROZONE INFORMATION TABLE AND WATER BUDGET CALCULATION:
Complete the hydrozone table for each hydrozone. Use as many rows as necessary to provide the square footage of landscape are per hydrozone.

WELS Section 6.1.3
(5.1.3 in newer
version) requires a
lockable master valve
Trees should be on separate
valves from shrubs,
ground-covers, and turf as
per WELS Section 6.2.7
(5.2.7 in newer version).
Revise plans in all cases.
How will these native
grass areas be
irrigated; Note

Provide the reasoning for overhead
spray irrigation versus subsurface
on these two roof gardens. Also,
why is one side a medium water
usage and the other side a low
water usage when they appear to
be utilizing the same low water
plants? Your hydrozone plan calls
out green roofs as low water.
