All the 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 conducted to 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.10). 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:
There was no overhead irrigation on site. Any lawn areas were synthetic. Trees were on a drip system valve,
and all landscaped areas utilized drip tubing. The dripline is subterranean, and the planting material has
been installed. In lieu of the catch can test, a visual confirmation of drip line performance, spacing and
staking was observed. This was conducted in multiple, random planters.
Observed on site, was per the standard 90% efficiency for pressure compensating drip & low-flow irrigation
per the Irrigation Association’s Guidelines. The Landscape Irrigation Auditor, 3rd edition book was used for
the report.
