Prior to completion of any sodding and seeding, re -grade ruts, footprints, washouts, or any other irregularities, and re- seed or re-sod repaired areas as shown or directed.
matter detrimental or toxic to the growth of plants, including Weeds, clods, R ocks or debris. On Slopes 1V:3H or flatter, remove all debris larger than 2 inches in any dimension. On cut Slopes 1V:1.5H or flatter, roughen the surface with furrows parallel with slope contours and loosen the Soil to a depth between 3 inches and 6 inches.
Passes at right angles to the slope in order to form seed-holding tracks in the Soil .
01040.49General Planting - Plant trees, shrubs, groundcover, vines, and bulbs using the following
practices:
• Inspect plants after arrival at the Project and before planting. Do not install plant materials until each required inspection by the Agency is complete. Replace plants not meeting the requirements of the Specifications with plants as specified or otherwise directed, at no additional 01040.49 985 cost to the Agency. Ini tial approval of plant materials for planting by the Agency will not constitute final acceptance. • Protect all plants during shipping, handling, storage, and planting from windburn or exposure to harmful weather conditions, and root or root ball drying. • When excavating planting holes, stockpile excavated Topsoil separately from subsoil. Do not include alkali Soil, subsoil, Gravel, debris or Rocks in the Topsoil . Dispose of any substandard excavated materials in a manner not harmful to plants or planting Wo rk. Scarify planting pit sides and bottoms to eliminate glazed surfaces. Dispose of excess Soil in a manner that is not harmful to plants or planting Work . • Do not plant in standing water unless approved by the Agency. If standing water is present within a plant pit, notify the Agency prior to planting to determine what corrective measures are required. • Excavate tree plant pits a minimum of twice the diameter of the plant root ball or 2 feet larger than the root ball, whichever is greater. Dig shrub pl ant pits a minimum of 1 foot larger than the root ball diameter. Dig pits to the same depth as the root ball, root mass, or container. Spread root systems of bare root plants and container stock as necessary to keep plants from being root bound. • Cleanly cut off broken or frayed roots of bare-root plants before planting. Spread out roots in their natural position within the pit and trim only damaged roots as approved by the Agency. Remove all labels, tags and attachment materials from the plants before F inal Inspection. • Set upright growing plants straight and plumb, and prostrate growing plants level to the ground surface. Set all plants so that, after settlement, they are at the same level as when growing in the nursery or container. • Place the backfill then add Soil amendments, Soil bio-amendments, and fertilizers as recommended by the Soil amendment and bio- amendment reports. Moisten backfill completely after placing to eliminate air pockets and minimize settlement of the backfill. Form a shallow (2 inch high) water -holding saucer in the Soil around the plant unless directed otherwise. • Balled and burlapped plants may be placed with the root ball wrapping removed or, if all materials are untreated and fully biodegradable, left in place. If the root bal l wrapping (burlap) is left around the plant, completely remove all tie wire, string or twine and fold down the burlap from the top half of the root ball. • Perform any required pruning using good horticultural practice appropriate to the type of plant. Prune to remove all dead, damaged, crossed or rubbing twigs and branches, and to compensate for loss of roots during planting. Make cuts close to the parent stem, but not flush or through the bark "knob" at the branch joint. Do not prune terminal ends of tr ee leaders without approval of the Agency. • Apply bark or wood chip mulch of the type and depth as shown. Correct contamination of new mulch due to the Contractor's operations at no additional cost to the Agency. Feather mulch into plant material trunks, stems, canes or root collars, and leave 1 inch below the top of junction and valve boxes, curbs and Pavement edges. Any mulch placed to a thickness greater than specified will be at no additional cost to the Agency. • Do not disturb protected existing veget ation unless approved by the Agency prior to construction. • Dig pits for street trees that have hard surfaces around them so the crown of the root ball is 3 inches below the finished surface of the surrounding grade. Perform initial watering and continue w ith the watering frequencies according to 01040.71.
01040.50 986 01040.50 Special Planting Requirements :
plants, unless otherwise specified:
season that the tree is dormant. Treat deciduous plants with anti -transpirant prior to excavation. Confirm with the Agency that the size of the spade is appropriate to the size and type of tree prior to beginning Work . Dig the receiving hole prior to digging the tree to be transplanted. Take care not to damage the tree bark. Refill the original hole after transplanting. Do not move Oregon White Oak (Quercus garryana) by this method.
root ball to be used for each plant. Begin digging at a diameter greater than the expected size of the root ball and remove dirt toward the plant until the surface roots show. When completely dug, secure the root ball with burlap and twine, wire basket or in a wooden box. Take special care to dig deep enough so that the taproot is not cut until it is smaller than 3/8 inch. Take care not to damage the tree bark. Refill the original hole and compact the Soil after transplanting.
Install perforated plastic drainpipe as shown. Add fertilizer, Soil amendments or bio-amendments to backfill Topsoil mixture. Stake or guy the tree as specified.
Provide one applic ation of anti -transpirant before transplanting, and one application of Vitamin B1 growth hormone after planting to each specimen plant according to the manufacturer's recommendations. Perform all replanting of specimen plants according to 01040.41 and 01040.42.
• Planting hoe capable of opening a vertical hole broken out on three sides, with a minimum blade length of 12 inches and width of 3 inches. • Planting shovel capable of opening a vertical hole broken out on three sides and at least 10 inches deep. • Normal bare-root planting method.
No pre-staking of planting locations will be required. The Agency will be present as planting begins and will approve the spacing, planting method, and areas to be planted before Work can begin. Vary plant spacing in order to allow seedlings to be planted in suitable Soil . During the planting process, remov e one tree at a time from the planting bag or other container to prevent drying of roots.
Place the roots of each seedling in the ground so that they assume a natural arrangement and do not twist, angle, bunch together or turn up at the ends. Plant seedlings so that the root collar is at or above the ground plane by no more than 1/2 inch. During planting, tamp Soil around the roots in the lower half of the hole. Then fill the hole to the surrounding Soil level and firmly pack so that no air pockets rema in around the roots.
Ensure that seedlings do not pull loose with a tug strong enough to detach a small group of needles or small branch ends as applicable. Place a stake at the edge of each planting pit and install browsing protection and browsing repel lant.
01040.53 987 (d) Tubeling Plants - Place the tubeling into the planting pit without breaking the root mass. Set the top of the root collar 1/2 inch above finish grade, and gently tamp Soil around the plant to compact the backfill. Place a stake at the edge of the plant pit and attach a browsing protector around each plant.
the root mass against drying, freezing or breaking. If possible, plant all collected stoc k the same Day as gathered, or transport to a local nursery for temporary storage until final planting.
If immediate planting is not possible, place collected plants in heavy paper or plastic with slightly damp Peat moss or sterile potting Soil. Store dormant plants at 32 °F to 37 °F until planting. Examine stored material frequently for signs of stress or disease and correct storage conditions as necessary. Plant collected plants before dormant bud development.
Compact the Soil firmly around the bulbs to prevent float -out and ensure good establishment. Dig holes large enough to naturally space bulbs within the planting area.
October and March. Notify the Agency if conflicts exist with permit requirements. Store all cut material in ventilated plastic containers that allow free flow of water. Protect root systems from excessive drying at all times. Do not store plants in airtight containers.
Plant stock w ithin 4 hours of harvest. If plants are a willow species, plant in the riparian zone on that portion of the slope where the plant stem ends will be in contact with year -round moist Soil as determined by the Agency. Make planting holes by forcing a steel bar or similar tool into the ground about 12 inches deep. Place the cuttings into the holes and tamp Soil firmly around the stems, leaving a minimum of 6 inches showing. Vary these dimensions as required for larger plant cuttings.
01040.51Planting Wet land Plants - When planting W etland plants, do not use Soil amendments,
mulch, or fertilizer. Plant rhizomes, tubers and plugs within the upper 2 inches to 3 inches in exposed muddy or moist Soils . When the water depth reaches or exceeds 1 inch notify t he Agency of the potential need for adjustment to the planting.
01040.52Placing Sod Lawn - Place sod only after approval of the Agency. Immediately before
placing sod, water the Soil bed to prevent drying of grass roots. Lay the first sod row in a straight line, then place subsequent rows parallel to and tightly against each other, staggering lateral joints. Do not stretch or overlap the sod. Tightly butt all joints. Do not use sod segments containing less than 2 square feet of surface area.
After placement, diagonally roll and thoroughly water the sod. Apply a second application of 22-16 -8 fertilizer at the rate of 510 pounds per 100 square yards and thoroughly water.
01040.53Mulch - Apply mulch according to the following:
visual inspection and approval. The approved sample will be the standard of acceptability for all mulch used on the Project. Apply bark mulch after beds are made free of W eeds and debris, the surface is brought to a smooth finished grade, and all planting Work (except for vines and groundcovers) is complete. Uniformly bark mulch planted areas to a nominal depth of 2 inches with bark mulch. Apply bark mulch so that it presents a smooth and even appearance as approved by the Agency (raking may be required).
01040.54 988 Keep bark mulch off plants, Structures, Roadways, Shoulders, walks , and lawns. Uncover all plants covered by mulch material as soon as possible and leave the site in a neat, clean and finished appearance. When planting vines or groundcover, rake bark mulch away from planting pits so that the bark is not contaminated. After planting, evenly spread excess Soil and rake bark mulch back into place.
Replace bark mulch that is displaced or blown away, and correct to the specified depth any bark mulch placed to a greater than specified depth, at no additional cost to the Age ncy.
Spread Rock or cinder mulch to a depth of 2 inches after planting trees and shrubs.
Spread compost on top of the Soil to a nominal depth of 3 inches.
of tubeling plants and seeding as required.
Ammonium Nitrate per 1,000 square feet to neutralize nitrogen loss.
01040.54Water - Water all plants at intervals as required to maintain and promote healthy growth
Avoid excessive watering of shrub bed areas that may leach herbicide and damage adjacent lawns or desirable or protected vegetation. Repair all lawn vegetation damage at no additional cost to the Agency.
Agency will test a 1 to 5 percent representative sample to ensure that the moisture stress level is below 20 bars of pressure and inform the Contractor if any material exceeds this limit. Any plant material found to have greater than 25 bars of pressure will be considered to be under extreme moisture stress. Provide sufficient water within 24 hours to bring the plant into normal range. The Agency will retest to determine the new representative pressure. Plant material that have 30 bars or greater will be considered to have reached its Permanent Wilting Point. Replace all such material during the next planting period. Testing will occur mid-day at the following times until the end of the Establ ishment Periods:
• After plant delivery, during temporary storage, and before planting. • At 1 month intervals throughout the summer season, up to the first fall rain or snow. • At weekly intervals during extremely hot or dry summer periods. • Any time the Agency believes the plant material may be under stress.
manufacturer's recommendation, depending upon specific applications.
01040.55Miscellaneous Items - Place or install miscellaneous items as follows:
Equipment . Ensure that one-third to one- half of each Rock is buried beneath finish grade. Verify all Rock placement with the Agency prior to installation.
01040.70 989 (b) Tree Grates - Install grates, frames, and appurtenances as shown and according to the manufacturer's recommendations. Place frames flush at sidewalks and place guards plumb according to the manufactures recommendations.
complete but before mulch placement begins. Place weed control geotextile with a minimum 4 inch overlap between rolls, turned under edges, and attached to the ground as recommended by the manufacturer.

recommendations.
into the ground at least 12 inches below the planting hole depth, or as shown. Do not drive stakes through t he root ball.
finish ground and the first whorl of tree branches.
01040.56Cleanup During Construction - Maintain the Project in a neat, orderly condition. Remove
unsightly construction materials at the end of each working shift. Clean all Pavement surfaces of mud, debris, or other materials that may, in the opinion of the Agency, cause problems. If material is not removed, the Agency reserves the right to have the cleanup Work performed and deduct the value of this Work from the monies otherwise due the Contractor.
Plant Establishment
01040.70General - The Contractor is responsible for the survival of all plant material until the end of
a Plant Establishment Period of 1 calendar year. The Plant Establishment Period will begin when all the original planting is complete. The original planting is considered complete when all the plant material has been planted to the satisfaction of the Agency. Establishment Period Work includes removing all plants that have reached their Permanent Wilting Point, are dead, dying, or which do not meet Specifications, and replacing them with healthy plants. All plants in place after this replacement will be recognized as the original planting and will be subject to the establishment Specifications . Repair, restore, and replace all plantings that have b een damaged by vehicles, vandalized, and stolen according to 00170.80.
01040.71 990 01040.71 Plant Care and Success Criteria - During the Plant Establishment Period , maintain plants in a vigorous growing condition by regularly doing t he following:
• Watering and fertilizing sufficiently to promote growth, unless otherwise specified. • Weeding, cultivating, pruning, and repairing. • Adjusting tree stakes and guys. • Controlling weeds before they seed according to 01040.48. • Controlling pests and Noxious Weeds before the reproductive cycle. • Removing dead or non- vigorous plants. • Replacing missing plants. • Re-mulching of plant bed areas.
The determination of a successful P lant Establishment Period will be made at periodic plant establishment inspections. A successful planting establishment for each inspection is defined as follows:
• All plants are surviving and have vigorous growth. • Plants are free of insects and disease. • Plants show signs of continuing health. • Plants have not reached Permanent Wilting Point. At the discretion of the Agency, certain types of regularly spaced plantings such as groundcovers may be measured using an area sampling method. To determine the rate of survival, set out (delineate) representative plots measuring 100 square feet at the completion of the original planting at random locations in each general planting area. The representative plots will be mutually agreed upon between the Contractor and the Agency. Mark the plot corners with permanent markers such as re- bar, including date and identification. Delineate a minimum of three plots per acre of new planting area.
The use of representative plots is intended to simplify the measurement of planting establishment Work . If Work within the representative plots does not accurately reflect the condition of the entire planting areas, the Agency reserves the right to reject all establishment Work .
01040.72Periodic Inspections - During the Plant Establishment Period, the Agency will make three
plant establishment inspections jointly with the Contractor at the following times:
• Spring, early May • Summer, mid -July • Fall, late September
Depending on when the Establishment Period begins, one of the above inspections will be the final inspection.
During each plant establishment inspection, the Agency may determine, based upon the specified success criteria, that corrective work is required. If so, the Agency will provide the Cont ractor with a written notice of required corrective work sent by hand- delivery or mail.
01040.73Corrective Work - Complete all corrective work within 15 Calendar Days after receiving
the written notice of the required corrective w ork to be taken. Th e 15-Day requirement excludes those days the Agency determines to be impractical for working.
01040.78 991 The Contractor will be allowed to replace plants outside the Planting Season to perform corrective work after each periodic inspection.
Provide plant replacements of the same variety, size, and quality as specified for the original plants, unless otherwise approved.
Notify the Agency when the corrective w ork is complete. When the corrective w ork has been re-inspected and is completed to the satisfaction of the Agency, the appropriate partial payment due the Contractor will be made. If the Contractor does not perform the corrective work within the 15-Day period after written notification, excluding those days the Agency determines to be impractical for working, the Agency may have the corrective w ork performed by others and deduct the entire cost of the corrective w ork from monies due or to become due the Contractor under the Contract.
01040.75Weed Control - Provide weed control according to 01030.42
01040.77Plant Establishment (Ornamental Areas) - In addition to these plant establishment
requirements, perform the following:
installed permanent or temporary irrigation systems, or such means as has been established for the Project. Avoid excessive watering of shrub areas adjacent to lawns that may leach herbicide and damage the lawn. Repair damaged lawns at no additional cost to the Agency.
If specified for the original planting, re-fertilize plants to promote vigorous growth.
Maintain the plant bed mulch at a 2 inch depth during establishment, unless otherwise specified. Rake to a smooth and even finish grade.
dead growth and crossing branches, maintain growth within available space, minimize overgrowth onto walks and walls, and minimize tree canopy damage from winds. Prune during the dormant season unless otherwise specified. Remove and dispose of all dead and critically damaged plant material to maintain the overall appearance of the Project.
planting Work is completed. Water, fertilize, and protect specimen plants against disease and infestation as required to ensure the plants remain healthy and vigorous. Final acceptance of transplanted specimen plants will depend on plant health and condition.
condition. A schedule of feeding, mowing, and general treatment, including thatching and aeration will be listed in the Special Provisions. Final acceptance of sod lawn areas will depend on its health and condition. Keep sod lawns mowed to a height between 1 1/2 inches to 2 inches.
Do not perform the first mowing until the sod is firmly rooted and se cure in place. Remove no more than one-third of the grass leaf during initial or subsequent cuttings.
01040.78Plant Establishment (Mitigation or Other Non -Ornamental Areas) :
temporary irrigation methods. Keep planted areas raked to a smooth and even finish grade. Maintain mulch within plant saucers at a 2 inch depth, unless otherwise specified. 01040.79 992
Soil test performed by a Soil ecology lab between the second and third periodic inspection. Present the recommendations to the Agency at the third inspection. Apply the amendments as recommended by the Soil test report and as directed by the Agency.
01040.79Final Inspection - After plant replacement Work and any other required Work has been
completed, the Agency will make a final i nspection. Ensure that all plant materials, planting beds and other facilities are according to the Specifications as a prerequisite for acceptance.
