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.

5. 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. Foliage around drains should be trimmed back every two weeks.
5. 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. LIGHTING
Bollard light standards are located along the Castaways Bluff Trail. This lighting system
and its maintenance is the responsibility of the City of Newport Beach.
29
Lae_ ,cape Maintenance Guidelines
MAINTENANCE RECOMMENDATIONS
1. Schedule and conduct reviews of the lighting system to make sure that the lights
are all functioning. Replace broken, damaged or missing light fixtures, glass or
bulbs immediately as required.
2. Reset clocks for bollard light schedule to accommodate daylight hours and daylight
savings time changes.
3. Systematically remove overgrown groundcover and plants that could obstruct
lighting. Periodically check entire lighting system, transformer, wiring and
connections to ensure that it is functioning according to plan.
4. Lighting maintenance should be taken care of by a licensed C-27n landscaping
maintenance contractor.
5. Follow manufacturer's specifications for light fixture care and replacement schedule
for lamp elements.
MAINTENANCE TIMETABLE
1. Bollard light standards should be inspected every week. Lights should be kept in
excellent working order and kept unobstructed by plant material
2. Overall lighting system review and inspection should occur every six months.
3. Timers for the lighting schedule should be checked and adjusted every two months
to accommodate changes in sunrise and sunset times. Lights should come on at
least one hour prior to dusk and turn off one hour after sunrise or as required to
meet minimum foot candle coverage for pedestrian safety as determined by the City
of Newport Beach.
EFFECTS OF DEFERRED MAINTENANCE
Inoperative light fixtures and broken bollards may directly affect pedestrian and bicyclist
safety along the trail system. Light levels should be maintained to provide optimum
visibility of the trail and any obstructions that may be located on the trail. Broken light
fixtures or wiring that is not encased could cause harm if tampered with by the general
public.
