CA 714.975.1434 CERTIFIED LANDSCAPE IRRIGATION AUDITOR (CLIA) BIG PICTURE LANDSCAPE Michael McMillen / 714.394.6126 / Bigpicturelandscapea_gmail .com Certified Irrigation Auditor #014256 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 city. 6). 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: The overhead spray lawn areas were operational with the controller, low efficiency nozzles were installed. Since the dripline is subterranean and the planting material is already installed and would be damaged if the dripline were unearthed, a drip catch can test was not performed. In lieu of the catch can test, the standard 90%efficiencyfor 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 Al-A6 • 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: Approximately4-10" • Slope: Overall site 1% • Compaction: yes • Runoff: No runoff observed • Standing Water: None observed • Hydrozone Separation: Yes • Mulch in Beds: Yes • Pressure Regulation: Not required / Isolation valve installed per plan • Controller: Hunter PHC-12 / WR-CLIK controller and hard wired weather sensor / rain shutoff • Valves: RB ASVF Installed on S,E side rear corner / Front W side of house. • Emitter Type: RB XFS 6-12 (.6 gph @ 12" o.c. row spacing @ 12"-18" o.c.) RB 1401 / RWS • Max Flow: 8.4 GPM • Distribution Uniformity: .90 /.77 • Precipitation Rate: 0.6 / 1.58 Punch list Items: 04/17/2023 (Compliance based on minor corrects during the maintenance period) 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.
