August 15, 2000 Lai, -,cape Maintenance Guidelines LANDSCAPE MAINTENANCE GUIDELINES August 15, 2000 1. INTRODUCTION 1.1 PURPOSE This Landscape Maintenance Guidelines (Manual) has been prepared for use by the Owners' Association, the property management company and maintenance contractors. It has been written with the layperson in mind, avoiding technical jargon as much as possible, while still including sufficient detail for adequate maintenance refurbishment and repair. The goal of this manual is to provide general maintenance recommendations which, when properly performed, will play a significant role in preserving the low maintenance drought tolerant planting that is in keeping with the native bluff planting. The manual is intended to be a dynamic, proactive tool to assist in the proper management of the landscape through programmed preventive maintenance and anticipated refurbishment and replacement rather than reactive, after -the -fact corrective maintenance. This manual establishes a minimum level of maintenance and does not specifically address other agency requirements that may be applicable. It is not intended to replicate or supersede the function, purpose or requirements of the City of Newport Beach, County of Orange, the State of California, or the federal government, or to supersede any other governmental or quasi -governmental controls. The recommendations contained in this manual are based upon existing local climate, soil, exposure, plant palette and site conditions. A change in some or all of these factors will require revisions to this manual to account for the then -current conditions. Unforeseen exceptional circumstances are likely to occur which will require special maintenance and outside sources of expertise. Reference literature, industry publications and professional consultants should be engaged for situations not specifically addressed in this manual, or for updating as maintenance techniques are improved. 1.2 SCOPE AREAS AND ACTIVITIES COVERED This manual provides recommendations for the maintenance, repair, refurbishment and replacement of common bluff -top landscape between the bluff walkway and the Castaways homeowner lot lines. 1 Labs. ,;ape Maintenance Guidelines Maintenance activities covered in this manual include: 1) pruning 2) edging 3) fertilization 4) weed removal, cultivation and aeration 5) herbicide and pesticide application 6) irrigation systems 7) landscape and area drains Complete lists of all plant material and irrigation equipment utilized in the Castaways Bluff - top are also included. These guidelines are recommendations and are not all-inclusive. This material should be reviewed and revised appropriately under the direction of the Owner's Association Board of Directors, their property management company and their Consultants at least once annually. 1.3 DEFINITIONS Crown Cleaning — Crown cleaning or cleaning out is the removal of dead, dying, diseased, crowded, weakly attached, and low -vigor branches and watersprouts from a tree crown. Crown Thinning — Crown thinning, also called thinning out or lacing out, includes crown cleaning plus the selective removal of branches to increase light penetration and air movement into the crown. Increased light and air stimulates and maintains interior foliage, which in turn improves branch taper and strength. Thinning reduces the wind -sail effect of the crown and the weight of heavy limbs. Crown Reduction — Crown reduction is used to reduce the height and/or spread of a tree. Thinning cuts are most effective in maintaining the structural integrity and natural form of a tree and extending the time when it will need to be pruned again. The lateral to which a branch or trunk is cut should be at least one-half the diameter of the cut being made. Crown Raising — Crown raising, also called skirting up, removes the lower branches of a tree in order to provide clearance for buildings, vehicles, pedestrians, and vistas. Crown Restoration — Crown restoration can improve the structure and appearance of trees that have been topped or severely pruned using heading cuts. One to three sprouts on main branch stubs should be selected to reform a more natural appearing crown. Restoration may require several prunings over several years to achieve the desired result. Thinning Cut — A thinning cut removes a branch at its point of attachment or shortens it to a lateral large enough to assume the terminal role. The lateral to which it is cut should be at least one-half the diameter of the cut being made. Thinning cuts are preferred in tree pruning. 2 Lai. :ape Maintenance Guidelines Heading Cut — A heading cut, also called stub cut, removes a branch to a stub, a bud, or a lateral branch not large enough to assume the lateral role. Heading cuts are prohibited and should be used only if extreme conditions warrant because vigorous, weakly attached upright sprouts are forced just below such cuts, and the tree's natural form is altered. 1.4 LIMITATIONS This manual is intended as a guideline and information source for the property manager and contractor to utilize in their landscape maintenance of the Owner's Association property. The program has attempted to cover anticipated normal day-to-day conditions but may not cover each and every maintenance situation which exists or which may arise in the future. The information and schedules used for preventive maintenance operations must be continuously reviewed, modified and updated at least annually to meet the ever changing maintenance needs. The information contained in this manual is only one source for the management of these landscape maintenance obligations. It is the responsibility of the contractor and property manager to use whatever sources are available to preserve and protect the physical assets of the Owner's Association including adopting procedures that address these maintenance concerns and obligations. EXCLUSIONS Guidelines addressing the maintenance of hardscape areas (walks, courtyards, decks, etc.), walls, gates, fences, pool, spa and associated equipment are not included in this manual. This manual is not intended to be used as a landscape maintenance specification nor as a contract scope of work between the management company/Owner's Association and a maintenance contractor. 1.5 RELATED DOCUMENTS AND REGULATIONS LOCAL ORDINANCES NEWPORT BEACH COMMUNITY DESIGN & MAINTENANCE STANDARDS CASTAWAYS CC&R'S 2. LANDSCAPE MAINTENANCE GUIDELINES 2.1 GENERAL LANDSCAPE ZONES The community of Castaways has several general landscape zones, each with its own unique character and maintenance requirements. These maintenance guidelines cover the Bluff -top landscape between the rear property line wall and bluff -top walkway. 3 Lan.. .,:ape Maintenance Guidelines BLUFF -TOP The Castaways Bluff -top is a special environment. It epitomizes the community's image and character. All maintenance activities should be performed with objective of preserving for posterity the native quality that one senses in this space. 2.2 PLANT MATERIAL CARE The following guidelines demonstrate accepted general practices for plant material indigenous to the area under typical meteorological circumstances. Changes in the following schedules and guidelines may become necessary as the landscaping is altered or affected by abnormal situations. TREES Trees add mass, texture and color to the landscaping environment. Healthy trees provide a natural source of beauty and shade and, with many species, return oxygen back to the environment through the photosynthesis process. Tree pruning should only be performed to direct growth and correct any structural weakness. The intent of pruning is to improve the health and appearance of the tree while allowing it to develop it's natural form. A list of the trees planted in the Castaways Bluff -top located in the Plant Materials List in this document. Note: The Eucalyptus citriodora trees installed along the Bluff -Top may be removed through by a vote of the Castaways Homeowners Association Board of Directors. Should the Castaways Homeowners Associate elect to remove these trees, a revised Landscaping plan is to be submitted to and approved by the City of Newport Beach. MAINTENANCE RECOMMENDATIONS 1. Prune dead, broken or diseased limbs from the trees as required year round to encourage healthy and proportional growth. Remove any trees that are diseased or severely damaged. 2. Schedule and conduct a review to determine the need for crown thinning or crown reduction of large mature trees. Prune oversized trees that could potentially fall and damage buildings or cause personal injury. 3. Regularly adjust and re -stake smaller trees, appropriately guiding the direction of their growth. Be sure that the tree ties do not cause abrasions to the bark. 4. Apply insecticides as needed to control infestation. 5. Be sure that tree roots have adequate drainage to help avoid root rot and related problems. 6. A routine thinning of tree species subject to breakage or uprooting due to top heavy or oversized conditions should be performed prior to winter storms to eliminate incidence of damage. 7. Periodically fertilize trees that are in remote areas of the common area. Most trees will not need fertilizing since they are located in areas that are regularly fertilized such as turf, slope and groundcover areas. 4 Lan..,. cape Maintenance Guidelines 8. A licensed C-27 landscaping contractor or licensed arborist should be hired to perform the necessary tree care. Tree removal may require the services of a tree contractor specialist having proper equipment and experience. MAINTENANCE TIMETABLE 1. Tree pruning of broken, dead or diseased limbs should be performed at least four times a year, or as needed to protect life and property. 2. Reviews for determining crown reduction, crown thinning requirements or tree removal should be conducted two times a year. 3. Tree reviews conducted to establish staking and tree tie adjustment requirements for young trees should be scheduled and performed four times a year. 4. Insecticides should be applied to affected trees two times a year. 5. Inspect tree root systems every three months and after rainy periods or heavy watering cycles to ensure adequate drainage. 6. Routine thinning of trees subject to breakage or uprooting should be performed in late November or early December. 7. Trees in remote areas not regularly fertilized should be individually fertilized two times a year. EFFECTS OF DEFERRED MAINTENANCE Sensible tree care is essential for building and resident safety and to the community's overall appeal. Infested, diseased, broken or over grown trees are unattractive and may eventually need to be replaced. Oversized trees, left unpruned, are a potential liability during extreme weather and geological conditions. SHRUBS AND VINES Shrubs and vines are ornamental in nature and are used to beautify and soften the architecture and walls and provide the understory landscape with color and texture. Climbing vines are used to soften garden and retaining walls. Shrub and vine pruning should be minimal, encouraging natural form and growth. Dead or crossed branches should be removed to promote improved health and appearance. A list of the shrubs and vines located in the Castaways Bluff -top landscape is located in the Plant Materials List at the back of this document. MAINTENANCE RECOMMENDATIONS 1. Systematically prune the shrubs with hand held clippers to maintain their natural shape and fullness. Remove any shrubs that are diseased, heavily damaged or destructive to surrounding desirable vegetation. Pruning should not detract from the natural growth of the plant species. Excessive pruning such as pollarding or topiary should be discouraged. 5 Lan..,cape Maintenance Guidelines 2. Train vines to grow in desired direction. Vines should be permitted to grow and climb on garden and retaining walls. 3. Regularly fertilize shrubs with slow release commercial 16-6-8 fertilizer. 4. Apply pesticides sparingly, only as needed to control severe or excessive infestations. 5. Utilize an appropriate pesticide, if necessary, to control snail infestation. 6. Pruning and pest control should be performed by a licensed C-27 landscaping contractor. Anyone applying pesticides must possess a current State Pesticide Applicators license. MAINTENANCE TIMETABLE 1. Shrubs should be pruned every three months. 2. Fertilize shrubs and vines twice yearly (March and September) or as needed. 3. Application of insecticides should be performed only as needed. 4. In areas where snail infestation is a significant problem, pesticides may need to be dispensed every month. EFFECTS OF DEFERRED MAINTENANCE Shrub and vine growth left unchecked becomes unruly and tends to sprawl, losing shape and aesthetic appeal and potentially interfering with other plants. Vines growing on metal fences and other high maintenance surfaces make upkeep difficult. Long-term neglect will eventually necessitate plant removal and replacement. GROUNDCOVER Groundcover consists of a variety of plants used to cover large expanses of slopes and other open areas as an alternative to turf. A list of the plants used in the Castaways Bluff - top landscape is located in the Plant Materials List in this manual. MAINTENANCE RECOMMENDATIONS 1. Replenish the soil nutrients with fertilizer to promote healthy and abundant plant growth. 2. Periodic application of herbicides to control the spread of weeds and undesirable plant growth may be needed to supplement the preferred hand removal method. 3. Remove any weeds which may have grown between the groundcover foliage and cultivate the soil on a regular basis. 4. Apply pesticides only as needed to control excessive pest proliferation and plant destruction caused by aphids, snails, insects and other pests. 5. Systematically prune back plant overgrowth to maintain uniformity and prevent other plants and shrubs from being impeded. Remove overgrown and unsightly vegetation as necessary. 6. Replace any bare spots with groundcover of the same species and variety. 6 Lan. .;ape Maintenance Guidelines 7 A licensed C-27 landscaping contractor should be hired to perform plant care, fertilizing, and application of herbicides. A properly licensed pest control company with State Pesticide Applicator licensed personnel may be contracted for regular pesticide applications. MAINTENANCE TIMETABLE 1. Fertilizer supplementation for groundcover plants should be applied at least four times a year. 2. Pre -emergent herbicide applications for weed control should be performed one or two times a year. 3. Cultivation and weed removal should be performed on a weekly basis. 4. Apply pesticides to the areas annually, or more often as needed to control excessive infestation. 5. Ground cover should be pruned back and shaped four times a year on sloped areas, and a minimum of once a month where groundcover is adjacent to walks. EFFECTS OF DEFERRED MAINTENANCE Overgrown groundcover areas detract from the overall landscape and can endanger other plants. Prolonged deferred maintenance could lead to pest infestation and premature plant replacement costs. 2.3 LITTER REMOVAL All litter and debris should be removed from the Castaways Bluff -top landscape areas at least four times per week. 2.4 FERTILIZATION The Collaborative West, Inc. is the Landscape Architect of record and designed the landscape improvements for Castaways. The following fertilization guidelines are general recommendations as determined by the soil fertility analysis conducted at the time of installation. These recommendations should be reviewed and adjusted by a professional Landscape Architect annually. A soil fertility analysis should be conducted annually in February before fertilization. FERTILIZATION MANAGEMENT Plants require light, air, water and nutrients to grow and prosper. Many of the nutrients are already available in the soil, but some are not. Supplemental nutrients need to be provided on a regular basis through the application of a commercial fertilizer. The goal of fertilizer management is to achieve proper nutrient levels sufficient to maintain a growth rate, which keeps the plant healthy and vigorous, but does not encourage rapid or excessive growth. 7 Lan_ _ ,;ape Maintenance Guidelines Any fertilizer containing all three major nutrients, or elements, (nitrogen phosphorous, and potassium) is called a complete fertilizer. If a fertilizer contains only one element it is a simple fertilizer. Six minor elements are also important to healthy plant growth and may need to be supplemented. They are calcium, magnesium, sulfur, iron, zinc, and manganese. The most common minor element deficiency is iron -poor soil. Iron is essential to the formation of chlorophyll in leaves. Iron deficiency is recognizable as yellowed leaves with green veins. The plant is said to be "chlorotic". This condition can be easily remedied with iron chelate fertilizer. The other minor elements may or may not need to be supplemented in the soil. Annual soil fertility testing should be utilized for proper fertilizer management. MAINTENANCE TIMETABLE Groundcover: Fertilize quarterly or as needed to maintain an appearance of dense, lush plant growth. Apply complete commercial fertilizer to provide 2 lbs. actual nitrogen per 1,000 sq. ft. per year in four applications. Vines: Fertilize semi-annually. Apply complete commercial fertilizer with 3 lbs. of actual nitrogen per 1,000 sq. ft. twice annually. Trees and Shrubs: Fertilize as needed and noted above and beyond the groundcover applications when plants are not located in groundcover and turf areas. Apply soluble nitrate fertilizer. Mature trees: 1/2 Ib. of actual nitrogen per inch of trunk diameter measured four feet from the ground. Note: All fertilizer is to be applied evenly with a thorough watering to follow. 2.5 PRUNING AND SHAPING DESIRED RESULTS Perhaps no other aspect of landscape maintenance is more controversial or more frequently abused than the practice of pruning. The reason for pruning is simple: to enhance the health, beauty, longevity and structural integrity of the plant. Pruning has three basic effects: it directs growth; it improves health; and it increases reproduction. Pruning should not be practiced with the goal of rendering every tree or shrub into unnatural, precise geometric forms. (The exception being when the design intent requires such a pruning practice; e.g., clipped hedges, topiary, pollard trees, etc.) In general, 8 Lan,_ _..ape Maintenance Guidelines though, the pruning should be done in a manner, which complements the plant's natural growth habit. Properly pruned trees and shrubs should not look to the casual observer as though they have been trimmed. Plants vary in their need for pruning. Some need a lot every year; some need a little in a lifetime; and some never need it unless they are injured. PROPER TECHNIQUES AND METHODS TREES The International Society for Arboriculture recommends, in general, that trees be pruned when they are under the least amount of stress. Most deciduous trees should only be pruned when they are dormant, typically during the fall and winter. Pruning times for evergreens are not as critical. However, pruning should be avoided during hot summer months as this increases the chance for sunburn damage. All trees should be pruned before their main growing season. Proper pruning of young trees will result in fewer and less drastic cuts as they mature. Care and attention should be devoted to pruning immature trees to promote the basic trunk and branching structure, which establishes the canopy framework. Once most trees become established, after a period of a few years depending upon species, only light trimming every 2-4 years should be required. Fast growing trees need more frequent pruning than slow growing trees. Tree pruning should not occur without valid reason. Most trees will grow and remain healthy without automatic annual trimming. However, pruning can be employed to improve the tree's appearance and vigor by removing dead, diseased, or broken branches; crossing lateral branches, sharp -angled vertical branches such as watersprouts (often called "suckers'); branches obstructing people, objects or utilities; unusually heavy foliage in areas of high winds; and branches which detract from the tree's desired appearance. As a general rule, no more than 25% of the tree's foliage should be removed at any one time. (Exceptions to this general rule are trees, which require thinning to prevent blow - down after its roots have been drastically pruned, or if a naturally brittle -branched tree canopy has been allowed to become too top heavy. Removal of too much of the canopy upsets the crown -to -root ratio, limiting the tree's ability to feed itself via photosynthesis. Removal of too much foliage also exposes previously shaded areas of the tree to direct sun. Trees can become sunburned. Sunburned trees are stressed and wounded trees, and are more subject to risk of disease and decay. The trees in the landscape have been selected with their mature height in mind. Therefore pruning should not be performed to reduce the overall height of the trees or to keep all trees at an arbitrary height or spread. Although once a common practice, "topping" or "stub cutting" is now recognized as detrimental, and is discouraged by most skilled and respected contractors. This practice drastically alters the tree's natural structure, destroys 9 Lan�.,cape Maintenance Guidelines its natural form, promotes weak "watersprout" growth, and often results in the ultimate removal of the entire tree. Careful pruning while the tree is young can preclude the need for such drastic measures later on. Alternatives to topping can be employed when it is determined necessary and desirable to reduce the tree's canopy. "Crown -reduction" is a less -injurious alternative and is the recommended method of dealing with trees that have become over grown for their particular situation. Selected smaller branches are removed back to the main trunk. Proper and careful thinning reduces somewhat the tree's height and spread while preserving its natural shape and growth habit. Where unusual circumstances dictate removal of a significant portion of a tree's canopy, crown -reduction should be accomplished in stages, adhering to the 25% maximum canopy removal guideline. Topping and stub cutting subject trees to severe stress, increasing the risk of pest and/or disease infestation. These practices can, and should, be avoided whenever possible. SHRUBS Shrubs in the landscape have been chosen in response to a variety of factors such as color, texture, shape, height, spread, water and sun requirements. Pruning should be limited to only that which is necessary to help them achieve their natural beauty and intended purpose. The landscape was designed in a naturalistic theme. Shrubs are intended to grow into one another so that they form a mass planting. The natural growth habits of the shrubs are intentionally varied and each should be encouraged and promoted by proper pruning techniques. Do not attempt to prevent shrubs from touching one another by unnatural shearing. As with trees, most shrubs should be pruned during their dormant period and when they are under the least amount of stress. Most shrubs should be pruned after flowering or immediately before their growth period starts. Most shrubs will thrive best if pruned no more than 2-3 times a year. GROUNDCOVERS & VINES As with trees and shrubs, groundcovers, vines and other plants are best pruned during their dormant period. The dormant period for these plants is typically October to February. SPECIFIC PROHIBITIONS 1. Topping or stub cutting of trees is prohibited. 2. Shearing or clipping of shrubs into unnatural or geometric forms is prohibited, except for designated hedges. 3. Wound dressings and tree paints have not been shown to be effective in preventing or reducing decay. Therefore, they are not recommended for routine use when pruning. 10 Lan__cape Maintenance Guidelines 4. Flush cutting of branches is prohibited. 5. Do not damage or destroy the branch bark ridge or branch collar when pruning. 6. Do not leave branch stubs. Make pruning cuts just above a lateral branch or healthy lateral bud. 7. Do not use hedge shears (manual or powered) to prune shrubs or groundcover. 2.6 STAKING AND GUYING ADJUSTMENTS Most trees require staking or guying after planting. Stakes and ties should be inspected every three months. Regular adjustments should be made to protect the tree from damage due to excessive movement, but still allowing the tree to move sufficiently to develop trunk strength. A program of gradually relaxing or loosening the tie constriction should be followed. The goal is to assist the tree, through proper pruning practices and stake and tie adjustments, to stand and support itself as soon as possible (within 1 — 2 years after planting). Trees should be checked regularly to prevent chaffing, girdling or other damage from the stakes or ties. REMOVAL Under most normal conditions, tree stakes should be removed when it is determined that the trunk is able to support the canopy without risk of damage. Tree species, size, condition, wind exposure and other factors need to be considered. When in doubt it may be advisable to loosen the ties to a point which affords the tree ample movement, but will prevent it from breaking or toppling in the event of heavy winds. 3. IRRIGATION MAINTENANCE GUIDELINES The irrigation system has been designed with the latest water management technology and practices. An important aspect of water management is regular monitoring of soil moisture (see below) and adjustment of the scheduling as needed. The controller should be reprogrammed each season as required by the plant associations found in each zone. Please discuss questions about the system with the Landscape Architect. It is intended that the use of these guidelines will encourage water conservation and will improve the health of the plants in the landscape. 3.1 SEASONAL CLIMATIC AND METEOROLOGIC VARIATIONS These guidelines assume the Orange County average rainfall of about 10" per year, generally falling between December and March. Schedules also assume the following average temperature ranges: January through March 35-65 degrees April through June 60-80 degrees July through September 70-95 degrees October through December 40-65 degrees 11 Lary_ . cape Maintenance Guidelines If the weather differs markedly, the scheduling must be adjusted. When temperatures exceed 95 degrees, the landscape may need more water. SOIL MOISTURE MONITORING If unseasonable weather occurs, or if plants appear to be under stress, or soils too wet, check the amount of moisture in the top six to nine inches by simply probing with a sampling tube, spade or trowel. Unless tensiometers are installed in every exposure of the project, there is no other way to be sure that the sprinkler schedule is optimum. TIME OF DAY The best time to irrigate is the early morning hours (e.g. 5-7 AM), avoiding peak domestic use periods. Watering at mid -day wastes water to winds and evaporation. Irrigation at night encourages fungi and other pathogens. Also, pipe damage at night will not be seen until morning, by which time property damage may occur and water will have been wasted. 3.2 PLANT ASSOCIATIONS AND WATER REQUIREMENTS Plants are grouped as much as possible to have similar needs within each sprinkler zone. These needs include: growth habit, rooting depth; sun and shade exposure; slope; soil type; wind; and climate. Do not introduce new plants unsuited for these conditions. The quantity is partially supplied by rainfall and the rest by irrigation. The controller should be programmed seasonally, and monitored regularly to provide adequate irrigation, and then fine-tune the schedule by checking soil moisture with a probe. DROUGHT TOLERANT TREES & SHRUBS These plantings require as much as 35 inches of water per year. Many plants require much less, surviving exclusively or largely on winter rainfall. By carefully monitoring plant health, irrigation may be reduced. DROUGHT TOLERANT SLOPE PLANTINGS Drought -tolerant groundcovers and shrubs are selected for most slopes because less water penetrates on slopes. These plants require approximately 30 inches of water per year. Because water runs off slopes, the scheduling must be broken into even more, and briefer, starts than on flat areas. 3.3 IRRIGATION SYSTEM Well -designed and maintained irrigation systems properly disburse controlled quantities of water throughout the variety of foliage and lawn areas. A complete system analysis should be performed at least annually by a professional Landscape Architect, or irrigation consultant, to determine irrigation problems, coverage, scheduling, water use and necessary adjustments and repairs. Quarterly inspections of the irrigation and drainage 12 Lan....cape Maintenance Guidelines systems documented in a written report describing the observations are recommended and should be conducted with the help of professional consultants. CONTROLLERS Irrigation controllers monitor the time and duration of landscaping irrigation cycles. The controllers at Castaways are remote controlled and electrically operated. Watering times are to be programmed for optimum water usage based on weather conditions and soil moisture testing. MAINTENANCE RECOMMENDATIONS 1. Schedule and perform periodic review of the controllers to insure proper function and to check watering cycle adjustments. 2. Adjust the irrigation controllers to correspond with PST and DST and in response to seasonal dry weather cycles. 3. Clean out valve boxes of debris as necessary. 4. Replace controllers as needed. Replacement controllers should be of the manufacturer and model number originally specified. Where substitutions are made, the maintenance contractor should submit performance data that verifies consistency with the original equipment. 5. A licensed C-27 landscaping contractor should perform the periodic reviews and controller adjustments. Controller replacements may require the services of a competent electrician. MAINTENANCE TIMETABLE 1. Review of the controllers should be performed once each month. Repair and replace as needed. Average life expectancy for irrigation controllers is 7 to 10 years. 2. Clock adjustments should be made twice yearly (April and October) to correspond with time changes, and as needed in response to seasonal demands for water. 3. Inspection and pressure check of the irrigation system's valves and connections should be performed on a monthly basis. 4. An annual review of the entire irrigation system for efficiency, coverage and condition by a professional landscape consultant is highly recommended. EFFECTS OF DEFERRED MAINTENANCE Irregular watering can adversely transform lush landscaping into an arid desert or muddy swamp. Most lawns and plant life will not survive these extremes, resulting in substantial loss of plant material. Over usage of water during drought periods can result in stiff penalty fees when use restrictions are enforced. 13 Late_ Jape Maintenance Guidelines VALVES Valves regulate the irrigation system's water flow through the different pipelines to many strategically located distribution points. The system at Castaways contains control valves, quick coupler valves, check valves, anti -siphon valves and remote control valves. MAINTENANCE RECOMMENDATIONS 1. Schedule and conduct periodic reviews of the valves and solenoids to verify proper functioning. Repair and replace as needed. 2. Keep valve boxes free of solids and debris. 3. Periodically clean and check all of the backflow preventers for leaks or damage. Schedule and conduct periodic checks of the backflow preventer valves to verify proper functioning. Exercise the valve regularly and repair and replace parts as needed. Clean the "Y" strainers regularly. 4. Reviews, repairs and replacements should be performed by a licensed C-27 landscaping maintenance contractor. MAINTENANCE TIMETABLE 1. Review of irrigation system valves and solenoids should be conducted once per week. All necessary repairs and replacements are to be performed immediately. 2. Control valve pressure regulating devices should be checked and adjusted on a monthly basis to assure optimum working pressure. Replace defective or inoperable regulating devices as required. 3. Clean out valve boxes of solids and debris as needed. 4. Clean and check the backflow preventers for leaks or damage monthly. 5. Periodic exercise of the backflow preventer valves should be conducted every six months. All necessary repairs and valve replacements are to be performed immediately. Clean the "Y" strainers annually. 6. Testing of the backflow devices by a certified backflow technician should be conducted annually during the anniversary month of the valves full operation. 7. An annual review of the entire irrigation system for efficiency, coverage and condition by a professional landscape consultant is strongly advised. EFFECTS OF DEFERRED MAINTENANCE Malfunctioning valves can alter the quantity of water supply for the lawn and foliage, endangering their well being and promoting premature removal and replacement. MAINLINES AND LATERAL LINES Pipelines are the interconnecting conduits that transport irrigation water from the source to the disbursement points. 14 Lan. .:ape Maintenance Guidelines MAINTENANCE RECOMMENDATIONS 1. Pipelines are usually constructed of PVC and, when installed correctly, are virtually maintenance free. Repairs may become necessary when trenching or digging disturbs the pipeline. 2. Conduct a review of the entire system to insure system integrity. Perform any repairs as needed. 3. Inspect risers, laterals and fittings that are exposed to the sun for deterioration and replace as necessary. 4. Check and repair as necessary any pipe anchoring or riser anchoring devices on exposed above ground laterals, vacuum breakers, risers or fittings. 5. All replacement pipe, risers or fittings for above grade systems should be UV (ultra violet) resistant. MAINTENANCE TIMETABLE 1. All necessary repairs should be done immediately. 2. Piping system reviews should be conducted two times a year. 3. An annual review of the entire irrigation system for efficiency, coverage and condition by a professional landscape consultant is strongly advised. EFFECTS OF DEFERRED MAINTENANCE Inoperative and broken pipelines will directly affect the ability of the system to adequately deliver water supplies, seriously jeopardizing lawn and plant life and leading to unnecessary replacement costs. Leaking pipelines waste precious water and can erode soil under hardscapes, threatening their integrity, and on hillsides, eventually washing away plants and topsoil. Broken pipes located near structures can lead to stucco and foundation problems with the potential for water damage to the interior living space. SPRINKLER HEADS AND RISERS Sprinkler heads function as the water distribution point for the irrigation system. A wide variety of designs are available to custom fit specific area applications. A list of the sprinkler heads and their capacities can be found in the section of this publication entitled Irrigation Equipment List. MAINTENANCE RECOMMENDATIONS 1. Schedule and conduct frequent sprinkler head reviews for function and adjustment needs. All sprinkler body or nozzle replacement shall be consistent with the equipment originally specified in the construction and as -built drawings. Where substitutions are made, the maintenance contractor should submit performance data for the material substitutes to verify that their performance is equal to the equipment originally specified. 15 Lan._cape Maintenance Guidelines 2. Adjust sprinkler heads so that buildings and walkways are not getting soaked or flooded during the sprinkling cycles. 3. Sprinkler heads and risers should be adjusted for height, pitch and throw to accommodate maturing landscaping. 4. Replace sprinkler heads, pipe and valves with equipment that meets the original design and operating specifications for size, type, strength, gallons per minute, and coverage. 5. Adjust anti -drain valves on sprinkler heads with low head drainage. 6. Regularly clean, straighten, flush and adjust sprinkler heads. 7. Reviews, adjustments and repairs should be performed by a licensed C-27 landscaping maintenance contractor or licensed irrigation designer or technician. MAINTENANCE TIMETABLE 1. Inspect sprinkler operation 1-2 times per week; more frequently during seasons with heavier watering schedules. Make appropriate sprinkler head adjustments and replacements as necessary. 2. Inspect sprinkler heads, anti -drain valves, and pressure regulators at least monthly. Clean, straighten, flush and adjust as necessary. 3. An annual review of the entire irrigation system for efficiency, coverage and condition by a professional landscape consultant is strongly advised. EFFECTS OF DEFERRED MAINTENANCE Improperly adjusted sprinkler heads waste water and place stress upon the landscape, potentially leading to costly plant replacement. Longer -term effects include damage to construction materials of structures and erosion of hardscape substructures, leading to material integrity failures. 4.

LANDSCAPE AND AREA DRAINS Landscape drains are located along the bottom of slope at the bluff -top walkway to control and remove excess irrigation and rain. This drainage system is the responsibility of the Owners' Association. MAINTENANCE RECOMMENDATIONS 1. Schedule and conduct reviews of the drains to make sure the protective gratings are in place and free from debris and that the grading slopes to the drains are adequate to promote drainage. Replace broken, damaged or missing grates immediately as required. 2. Systematically remove overgrown groundcover and plants that could obstruct water drainage. 3. Periodically check the entire drainage system to ensure that it is functioning according to plan. Drains should be jetted out as necessary. 4. Drain maintenance should be taken care of by a licensed C-27 landscaping maintenance contractor. MAINTENANCE TIMETABLE 1. Drains should be inspected every week and kept unobstructed. 2. Inspect the drain grates every six months and replace as needed. 3. Reviews of the grading to the drains should be conducted every six months. 4.

Drain inspections and flushing/jetting should be conducted three times a year, twice during the rainy season and once during the spring or early summer. One of these inspections could be scheduled during the gutter and downspout inspection and cleaning procedures. EFFECTS OF DEFERRED MAINTENANCE Area flooding from obstructed drains or broken irrigation drains can drown plants and generate root rot, prematurely killing the foliage, requiring early plant removal and replacement costs. Weather and plant growth can alter the grade slopes toward the drains causing pooling and inadequate drainage. Excess water can be extremely detrimental to structures, roads and walkways by damaging construction materials and eroding substructures essential for structure and hardscape integrity. 6.
