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. 5). 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. Shrub ZONES / STATION A1-A5 · Irrigated Area: Zones separated based on Full sun South/ West side of project · Plant Material: Shrubs - Low water · Plant Condition: Traditional · Microclimate: Full Sun · Soil Category: Silty Clay Loam · Root Depth: Approximately 2-10” · Slope: Overall site 2% to 2:1 at back of property. · Compaction: yes · Runoff: No runoff observed · Standing Water: Some additional water from heavy rains, typical on adjacent properties. · Hydrozone Separation: Yes · Mulch in Beds: Yes · Pressure Regulation: Not required / Isolation valve installed per plan · Controller: Hunter Pro-C controller w/ Solar Sync. · Valves: Install per plans · Emitter Type: Netafim TLHCVXR5-12 w/ Techline fittings (.53 gph @ 12” o.c row spacing @ 12” o.c.) · Max Flow: 9.0 GPM · Distribution Uniformity: .90 · Precipitation Rate: 0.6 Punch list Items: 01/04/2022 (Compliance based on the following corrects during the maintenance period) · Waterproof connections required to al wire connections. · Contractor to provide owner with controller charts and Record Drawings. 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.
