Cool Season Grass 3- 7 days None 3-10 days 7 - 14 days 6"-10" (Rye, Fescue)
These guidelines are for established plants (1 year for shrubs, 3 years for trees). Additional water is needed
for new plantings or unusually hot or dry weather. Less water is needed during cool or rainy weather. Drip run
times are typically 2 hours or more for each waterino.
Watering Schedule for Newly Planted Desert Adapted Plants
How much and Spring Summer Fall Winter How Often
Mar-May May-Oct Oct- Dec Dec-Mar
Weeks 1 and 2 every 3 - 4 days every 1 - 2 days every 3 - 4 days every 3 - 4 days
Weeks 3 and 4 every 6 - 7 days every 3 - 4 days every 6 - 7 days every 6 - 7 days
Weeks5and6 every 7 - 1 O days every 4 - 6 days every 7 - 1 O days every 7 - 10 days
Weeks 7 and 8 every 10- 14 days every 7 days every 10- 14 days every 10-14 days
AfterWeek8 Gradually extend the time between irrigations until plants are established.
NOTE: After the eighth week, move the drip emitters to the outer edge of the root ball. High water-use plants
may require more frequent irrigations. Water deeply to 24 - 36 inches for trees, 18 - 24 inches for shrubs, 8 -
12 inches for ground cover, vines, cactus, succulents and annuals, and 6- 10 inches for warm and cool
season grasses.
LANDSCAPE IRRIGATION AUDIT REPORT
Project Name: Phuoc Phan Residence
Address: 1221 Berkshire Lane, Newport Beach CA
Design / Installation: Dave Pedersen
20271 Acacia St., Ste 120 Newport Beach, CA 92660 949.251.8999
Certified Landscape Irrigation Auditor (CLIA): BIG PICTURE LANDSCAPE
Michael McMillen / 714.394.6126 / Bigpicturelandscape@gmail.com CLIA #014256
All of the zones / hydrozones on the irrigation systems were evaluated with a visual inspection. As per your
request, we evaluated the irrigation systems in accordance with the California Model Water Efficient
Landscape Ordinance (MWELO).
SUMMARY
This audit was inspect the overall site irrigation systems within the limits of construction. The irrigation
systems are new systems utilizing POTABLE water.
IRRIGATION PLANS:
Each hydrozone identified on the plans were executed in the field, (Total valve qty. 4). Each system layout,
components and functionality have met all the requirements of the Irrigation Plans.
MWELO:
The California Model Water Efficient Landscape Ordinance has been adopted by the City as the standard for
new construction and irrigation installations based on AB1881.
UNIFORMITY:
Since the dripline is subterranean and the planting material is already installed and would be damaged if the
dripline was unearthed, a drip catch can test was not performed. In lieu of the catch can test, the standard
90% efficiency for pressure compensating drip & low-flow irrigation per the Irrigation Association’s Landscape
Irrigation Auditor, 3rd edition book was used for the report.

Zone Audit Conclusion: PASS, project IS within compliance to begin maintenance.
The irrigation systems were evaluated and based on the Irrigation Association Audit rules/guidelines and
MWELO requirements.
The MWELO is a calculation noted on your landscape construction documents. This state required calculation
defines landscape irrigation estimated and maximum water used for the landscape. The state of California is
currently in a government declared drought and water use restrictions are being enforced statewide.
It is the responsibility of the Homeowner (Person maintaining the landscape), to determine when a plant
material is established, and the irrigation schedule should be adjusted as needed to sustain the plant while
being water efficient.
