IR <br />R <br />I <br />G <br />A <br />T <br />I <br />O <br />N <br />CA <br />L <br />C <br />U <br />L <br />A <br />T <br />I <br />O <br />N <br />S <br />·Irrigation/Watering Responsibility <br />o It is the responsibility of the Maintenance Contractor to operate the <br />irrigation system in an efficient manner and to minimize water waste. <br />It is the Maintenance Contractor's responsibility to adjust the system to <br />apply water in accordance with plant requirements based on weather, <br />soil, and site conditions. The irrigation program shall be scheduled to <br />minimize water waste through runoff, excessive irrigation run times, <br />utilize CYCLE SOAK scheduling when applicable. It is the responsibility <br />of the Maintenance Contractor to operate the irrigation system based <br />on local municipal guidelines. <br />·Irrigation Activation <br />o Activate irrigation system in spring (or when weather permits). Charge <br /> mainline in February or March to check for leaks and/or malfunctioning <br /> valves. <br />o Turn on backflow preventers, open gate valves and activate booster <br /> pumps if installed. <br />o Set the irrigation controller to RUN MODE and verify that all programs <br /> are activated and set up to be run in Self Adjusted mode. <br />o Site verification and adjustments. This includes turning on each zone, <br /> monitoring for leaks or malfunctioning parts, cutting grass away from <br /> sprinkler heads and adjusting sprinklers for proper arc and maximum <br /> efficiency. <br />o Verify that drip irrigation is functional and that distribution tubing has <br /> not been cut or broken during non operational period. <br />o Service, clean and adjust and weather sensor system. This is critical <br /> for ALL self adjusting controllers. <br />o If applicable service irrigation booster pump, this need to be completed <br /> by the manufacturers certified technician. <br />·Irrigation Monitoring/Landscape Watering <br />o Check the ET/Weather Based self adjusting system programming, Flow <br />Sensor and Master Valve operation and programming; adjust as <br />required to ensure proper operation. <br />o ALL Backflow Prevention Devices are to be maintained as per Local city <br />or county codes. <br />o All turf areas shall be monitored to determine the need for <br />supplemental irrigation. Frequency and duration of each watering will <br />be dependent on local weather conditions. To determine the need for <br />watering, Landscape Maintenance Contractor shall use a soil probe to <br />examine the first 6-12” of the soil profile. If the soil is cool, damp and <br />holds its shape, watering is not necessary. Plant material roots should <br />be encourage to root as deep as possible, this is accomplished by deep <br />root watering, longer irrigation run times and utilizing CYLCE SOAK <br />method. Frequent shallow irrigation scheduling is ineffective and will <br />only promote shallow rooting and require excessive water waste. <br />o Groundcover and shrub beds shall be watered using an automatic <br />irrigation system. The entire groundcover/shrub bed shall be soaked to <br />a depth to maximize healthy plant root growth. Irrigation run time to <br />be based on irrigation device precipitation rate (not flow rate) and plant <br />material irrigation demand. (Use WUCOLS reference for plant watering <br />needs). In the event of establishing plants, or compromised soil profile, <br />watering frequencies may be adjusted. <br />o Establish time settings and intervals of irrigation water application for <br />each valve of all irrigation zones. Make adjustments when necessary to <br />correspond to variable watering requirements. Check for coverage and <br />plugged emission/nozzle devices. Clean devices and adjust devices <br />while maintaining the system in proper working order. <br />o ALL automatic controllers will be programmed to apply water during <br />hours as permitted by local town, city or county ordinances. <br />·Irrigation System Repair <br />o Cleaning and adjusting the sprinklers heads are the Maintenance <br />Contractor's responsibility. Repair and/or replacement of any <br />vandalized or malfunctioning component beyond Maintenance <br />Contractor's control is the responsibility of the Owner/Agent. Any <br />damage caused by Maintenance Contractor will be repaired by <br />Maintenance Contractor at no cost to the Owner/Agent. <br />o All irrigation repaired or replaced MUST be in accordance with the <br />original irrigation design, local city or county guidelines and must <br />provide the maximum efficiency as possible so as NOT to waste water. <br />o ALL Drip systems are to be manually flushed a minimum one time per <br />year and filters to be cleaned on a regular basis. <br />o All damaged and repaired pipe MUST be flushed of all debris. <br />Maintenance Contractor to guarantee full operational and efficient <br />performance of repaired systems. <br />o Repairs to Backflow Prevention Devices must be conducted by a trained <br />certified backflow technician. <br />o It is recommended that ALL irrigation maintenance and repair be <br />performed by California Licensed and/or Certified contractor. Not <br />maintaining irrigation systems in an efficient manner will result in plant <br />and landscape degradation and additional maintenance costs. <br />·Irrigation System Winterization <br />o Where applicable, shut off and drain irrigation system(s) at the end of <br />the irrigation season. Turn off all main supply valves, open all manual <br />drain valves, and bleed valves on backflow prevention devices. Perform <br />winterization prior to November 1st. <br />·Irrigation Start up <br />o Flush all drip lines at flush points. <br />o Remove and clean all filters and replace any damaged filters. <br />o Check that all weathers sensors are functioning and replace batteries as <br />needed. <br />IRRIGATION MAINTENANCE <br />MWELO CALCULATIONS <br />PRECIPITATION RATES & SOIL INTAKE RATES <br />IRRIGATION SCHEDULE <br />DE <br />S <br />I <br />G <br />N <br /> <br />F <br />O <br />C <br />U <br />S <br />LA <br />N <br />D <br />S <br />C <br />A <br />P <br />E <br /> <br />A <br />R <br />C <br />H <br />I <br />T <br />E <br />C <br />T <br />U <br />R <br />E <br /> & <br /> <br />C <br />O <br />N <br />S <br />T <br />R <br />U <br />C <br />T <br />I <br />O <br />N <br />DESIGN <br />FOCUS <br />PO BOX 485 <br />BEN LOMOND, CA 95005 <br />(831) 336-3100 <br />47 <br />5 <br /> <br />& <br /> <br />4 <br />9 <br />3 <br /> <br />S <br />T <br />. <br /> <br />J <br />O <br />H <br />N <br />PL <br />E <br />A <br />S <br />A <br />N <br />T <br />O <br />N <br />, <br /> <br />C <br />A <br />REVISED: 10/10/2025 <br />DESIGN BY: 4Binc. <br />DRAWN BY: 4Binc. <br />SCALE: NTS <br />IR2.8
