All of 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 gty.7). 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 separate bubbler
valve, and all landscaped areas utilized drip tubing/ drip mats. The dripline is subterranean, and the planting
material has been installed. 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. A visual confirmation of drip line spacing (multiple locations), was
conducted in random planters. The system also implemented drip indicators that were also confirmed
operational.
