Site has new landscape areas totaling approximately 1,438 square feet. Root zone: New landscape area with minimal root zone. Slope: Flat throughout project. Note: The main focuses of this irrigation audit was to verify that all irrigation systems are being used as efficiently as possible to conserve water. Runoff and overspray were inspected as well. As required by City Landscape Ordinance. This audit report does not offer any warranty. This report only illustrates findings during the time of audit. Irrigation System Test Irrigation Audit was performed on May 23, 2024. This process involves inspecting complete irrigation system on site, from point of connection, to all ends of irrigation system. Every irrigation zone was inspected thoroughly. Site was also inspected to verify the precipitation rate and distribution uniformity of each station. Distribution uniformity [DUj is extremely important to verify since it can cause future problems to plants and ultimately waste water. An example of the importance of irrigation efficiency can be seen in fig. 1 (from Landscape Irrigation Auditor 3`d Edition) in the next page. z Figure 1. Irrigation uniformity Uniform r . t • •.� Yr' w 4~'�VYM •+Y+A� n Turf Area Irrigation Efficiency Non -Uniform ❑ Water Infiltration Irrigation efficiency is the ratio between the amount of water applied and the amount of water that is beneficially used (water that is used by the plant or used to wash harmful salts from the root zone). A nonbeneficial use is water that is lost to evaporation, runoff, or deep percolation (see fig. 2, from Landscape Irrigation Auditor 3rd Edition). Onceyou have maximized the distribution uniformity, your irrigation efficiency can be greatly improved. Figure 2. Irrigation uniformity Efficient M • • ! in A • ♦+� f Y Aa M., M ♦ ♦ •.

All drip valves are using pressure regulators. All sprinklers are pressure regulating pop ups for optimal pressure. Water is being used efficiently, runoff is being controlled. The current installed controller is an evapotranspiration type controller as plans require. Contractor replaced controller May 22, 2024, to meet this requirement. Run sprinklers at 5-minute intervals to control runoff. This table contains statistics for each individual station audited. It lists information by station number, type of plant material, operating pressure, irrigation type, and pass or fail per high standards of an irrigation audit. Station numbers reflect plan number to keep report consistent per Landscape Irrigation Plans. Field irrigation numbers differ, however what is being irrigated remains the same. Station # Type of Plant Material Type of Irrigation Operating Water Pressure (psi) pass / Fail 1 Turf and Trees Spray 30 Pass 2 Turf and Trees Spray 30 Pass 3 Shrubs Drip 30 Pass 4 Shrubs Drip 30 Pass 5 Shrubs Drip 30 Pass 6 Shrubs Drip 30 Pass Passing standards included: Broken pipes, Missing or broken heads, Missing nozzle, clogged nozzle, heads not turning, arc misalignment, low head drainage, leaking seals or fittings, spray deflected or blocked, sunken head, tilted heads, mismatched heads, spray or rotor inadequate separation, spacing uneven, valve malfunction, more than one hydrozone per one valve, overspray, uncontrollable runoff, and inadequate distribution uniformity. If any of these actions has not been met station is marked as failed. a Conclusion All of the irrigation zones for the project were evaluated thoroughly. Complete site irrigation system has great uniformity. The current installed controller is an evapotranspiration type controller as plans require. Runoff is controlled by having spray heads run at 5-minute intervals. Project is doing a greatjob of conserving water by using pressure compensating devices and controlling run off. All irrigation devices were emitting at 30 PSI this is optimal pressure. Project is in excellent quality condition. If the Tran Residence continues to promote best management practices (BMP's), project will continue to have high standards and conserve water. ca p e Irri.9 - o 0� CLIA 47 'I'd. �\o CgllON ASSQ�\P 5 Juan Alvarez CLIA, XCCS, WUEP Certified Landscape Irrigation Auditor License# 114074 (619)212-5890 Appendix E LANDSCAPE INSTALLATION CERTIFICATE OF COMPLETION I hereby certify that: (1) 1 am a professional appropriately licensed in the State of California to provide professional landscape design services.
