# [GENERAL]{.underline} {#general .SECTION-1}

## Summary specimen {#summary-specimen .SECTION1.01}

A.  Work Under this section includes but is not limited to, planting of
    trees, shrubs, and ground covers, back filling, filter fabric
    installation, mulching of grounds and other materials necessary to
    accomplish finished construction as indicated in on Contract
    Drawings.

B.  This section covers the requirements for materials, and services
    required for complete installation of plant material and related
    landscape items as indicated on the Contract Drawings and/or
    specified herein.

C.  Substitution: Plant material substitutions shall not be made without
    the approval of the SDR. The use of material differing in kind,
    quality or size from that specified will be allowed only after the
    SDR is convinced that all means of obtaining the specified materials
    have been exhausted.

D.  Sustainable Site Design: The use of xeriscape principles to promote
    the use of native, well-adapted plant material is encouraged. This
    practice reduces maintenance and irrigation requirements. Plants
    that are drought tolerant require watering until establishment and
    after, water can be drastically reduced except in periods of sever
    drought.

E.  Conservation and protection of natural resources at the site is
    important. Any disturbance of material resources occurring during
    planting operations shall be kept to a minimum.

F.  Plant Names: The scientific and common plant names as indicated on
    the Contract Drawings are generally in conformity with the approved
    names given in the Standardized Plant Names (SPN), 1980 Edition. The
    names of varieties not included therein are generally in conformity
    with the names accepted in the nursery trade.

G.  Related Sections: Refer to the following sections for related work:
    Paving, Hardscape, Planting, Seeding, and Drip Irrigation.

        nursery before moving and again two weeks after planting. Do not
        drop stock during delivery. Do not remove boxed or
        container-grown stock from containers until planting time.

    4.  If planting is delayed more than 6 hours after delivery, set
        trees and shrubs in protected area to avoid weather and
        mechanical damage. Keep roots moist.

R.  Storage

    1.  Place mulch in dry storage area away from contaminants.

    2.  Deliver packaged materials in original unopened containers
        showing weight, analysis, and name of manufacturer, in
        conformance with state law.

            from drying at all times by covering the balls or roots with
            moist sawdust, wood chips, shredded bark, peat moss, or
            other similar materials. All plants shall be watered as
            necessary until planting.

        b.  Plants shall be stored in areas designated or approved by
            the SDR.

S.  Handling

    1.  Care shall be taken to avoid damaging plants being transported
        to the project site. Plants shall not be lifted by the trunk or
        stem, and shall not be dropped. During transportation to the
        site, plants shall be properly covered to prevent drying out.
        Damaged plants will be rejected and shall be removed from the
        site immediately.

    2.  Lift trees only by methods that will not damage bark or loosen
        trunk from rootball or otherwise damage the appearance, health
        or growth of the tree.

V.  Do not plant when conditions detrimental to plant growth \[such as
    rubble fill, adverse drainage conditions, or obstructions\] are
    encountered. Immediately notify the SDR.

W.  Coordinate plant locations with the location of irrigation heads. If
    any discrepancies are found between the two, notify the SDR
    immediately and do not proceed with further work in that area until
    notified the SDR.

X.  Plant trees and shrubs after final grades are established and prior
    to planting of lawns, unless otherwise deemed acceptable by the SDR.
    If planting of trees and shrubs occurs after lawn work, protect lawn
    areas and promptly repair damage to lawns resulting from planting
    operations.

## WARRANTY {#warranty .SECTION1.01}

Y.  All plant material shall be guaranteed to be in a live, healthy, and

        On slopes, maintain 4-inches below surrounding grade on the
        downhill side.

    4.  Center and set trees plumb and with the full side of the plant
        facing the front of the bed with top of ball 4-inches lower than

        Excavate pits large enough to set each plant. Backfill with
        excavated planting soil mix. Water thoroughly. Fill depressions
        and level high spots.

F.  Apply anti-desiccant using power spray to provide an adequate film
    over trunks, branches, stems, twigs and foliage according to
