<br />I. Final Approval
<br />J. Warranty
<br />2. The Landscape Contractor shall notify the site contractor and Landscape Architect
<br />of any discrepancy between the Drawings and/or Specifications and actual conditions.
<br />Specifications shall take precedence. No work shall be done in any area where there
<br />is such a discrepancy until the discrepancy has been clarified and a written response

<br />a nursery to obtain all plant materials noted on the plans and have them available for
<br />inspection by the Owner and the Landscape Architect. Upon approval of the plant
<br />material, the contractor shall purchase the material and have it segregated and grown
<br />for the job. The deposit necessary for such contract growing (if required) is to be born

<br />assure healthy, normal growth.
<br />D. Fertilizing:
<br />1. Fertilize all planting with he following or as noted in the required Horticulture
<br />Soils Report. At the end of the first 30 day and at 30 day intervals, apply top
<br />dress fertilizer. The fertilize shall be 16% nitrogen, 6% phosphoric acid, 8%

<br />Weeding, Cultivating, and Cleanup: Planting areas shall be kept neat and free
<br />from weeds and debris at all times and shall be manually weeded at not more
<br />than 10-day intervals. Said areas shall be weed free at the end of the
<br />Maintenance Period. Apply pre-emergent weed control per city standards, verify

<br />be mowed weekly at a height of no less than 2".
<br />G. Tree and Shrub Care
<br />1. Maintain large enough basin around plants so hat enough water can be
<br />applied to establish moisture throughout the major root zone. When hand water,
<br />use a water wand to break the force. maintain mulch at a depth of 3" minimum
<br />depth to reduce evaporation and frequency of watering.
<br />2. Pruning Trees: Prune trees to develop permanent scaffold branches that
<br />are in diameter than the trunk or branch to which they are attached; which have
<br />vertical spacing from 18" to 48" and radial orientation so as not to overlay one
<br />another, to eliminate diseased or damaged growth; to eliminate narrow
<br />V-shaped branch forks that lack strength; to reduce and wind damage by
<br />thinning out crowns to maintain growth within space limitation; to maintain a
<br />natural appearance; to balance crown with roots.
<br />4. Trees shall not be topped and shall be allowed to grow to the full genetic
<br />height and habit. Under no circumstance will striping of lower branches
<br />(raising-up) of young trees be permitted. Lower branches shall be retained in a
<br />"tipped back" or pinched condition with as much foliage as possible to promote
<br />caliper trunk growth(tapered trunk). Lower branches can be cut flush with the
<br />trunk only after the tree is able to stand erect without staking or other support.
<br />Remove sucker growth if deemed appropriate by he Owner's authorized
<br />representative.
<br />5. Thin out evergreen trees and shape when necessary to prevent wind storm
<br />damage. The primary pruning of deciduous trees shall be done during the
<br />dormant season. Prune damaged trees or those that constitute health or safety
<br />hazards at anytime of the year as required to eliminate unsafe conditions.
<br />6.Trimming Shrubs: The objective of shrub pruning is the same as for trees.
<br />Do not clip shrubs into balled or boxed forms unless such is required by the
<br />design and directed by the landscape architect. Make pruning cuts at lateral
<br />branches or buds or flush with he trunk. "Stubbing" will not be permitted.
<br />7. Staking and Guying: Remove stakes and guys as soon as they are no longer
<br />needed. Periodically inspect stakes to prevent girdling or rubbing that causes
<br />bark wounds. Replace broken stakes and ties with specified materials. All
<br />stakes shall be removed at one year after completed installation, if not sooner.
<br />H. Replacements: The contractor shall replace any plant materials that die or are
<br />damaged. Replacement shall occur within seven (7) days of plant death or
<br />damage. Replacements shall be made to the same Specifications as required
<br />for original plantings.
<br />I. At the termination of the Maintenance Period, all plant materials shall be alive,
<br />healthy, undamaged, free from infestations, and in flourishing condition.
<br />Plantings that do not conform to Specifications shall be replaced and brought to
<br />a satisfactory condition before final acceptance of the work can be made.
<br />20. Following the 90 day Maintenance Period, there will be a final inspection by the
<br />a satisfactory condition before final acceptance of the work can be made.
<br />20. Following the 90 day Maintenance Period, there will be a final inspection by the
<br />Owner, Landscape Architect, and the City Representative. Items noted during the final
<br />inspection as not in accordance with the maintenance requirements shall be corrected
<br />by the Contractor prior to Final Acceptance of the landscape work.The 1 year
<br />warranty period shall begin with the Final Acceptance and the Owner's acceptance of
<br />the project. A letter documenting Final Acceptance, signed by the Owner's Authorized
<br />Representative, the Contractor and the Landscape Architect shall be issued, with the
<br />starting date and the completion date of the warranty period.
<br />21. Warranty
<br />A. Trees, shrubs, groundcovers and other plant materials shall be guaranteed to
<br />take root, grow and thrive for a period of one year after acceptance of the Work
<br />by the Owner. Plant materials which do not thrive as the direct result of the
<br />installation procedure or maintenance practices during the maintenance period
<br />of the installing contractor shall be replaced by the installing contractor. This
<br />shall be as determined by the Owner.
<br />B. Plant materials which fail as the result of poor maintenance practices after
<br />acceptance of the landscape by the Owner (at the end of the maintenance
<br />period) shall be the responsibility of the Owner's maintenance contractor.
<br />C. Trees or other plant materials that die back and lose the form and size originally
<br />specified shall be replaced, even though they have taken root and are growing
<br />after the die-back.
<br />D. Within fifteen days of written notification by the Owner, remove and replace
<br />warranted plant materials which, for any reason, fail to meet requirements of
<br />Warranty. Replacements shall be made to the same Specifications required for
<br />original materials and shall carry the same Warranty from the time they are
<br />replaced.
<br />22. The intent of the layout design and planting is to establish a high quality landscape
<br />installation. Future plant growth should require minimum trimming, thinning and
<br />pruning of the plant materials. Plant spacing is designed to allow for natural full growth
<br />and should not need the removal of some plant materials if over crowding occurs. The
<br />planting installations will require maintenance and management, by knowledgeable
<br />and trained personnel, to assure a quality project.
<br />23. Water Efficient Ordinance / AB 1881 Requirements
<br />This project requires compliance with AB 1881, Model Water Efficient Landscape
<br />Ordinance, the Maintenance contractor shall provide the following:

<br />authorized representative, keys to each controller and written instructions on
<br />how to turn the system off in case of emergency.
<br />C. Check system weekly fir proper operation and coverage.Lateral lines shall be
<br />flushed out after removing the bubbler or two at the end of the lateral.
<br />D. Repair damages to irrigation system at Contractor's expense. Make repairs
<br />within one watering period.
<br />25. Drainage System
<br />A. All drains in landscaped areas, subsurface drain lines and grates shall be kept
<br />free and clear of leaves, litter and debris to ensure proper and free flow of water.
<br />B. Drain lines shall be periodically flushed with clean water to avoid build up of silt
