during periods of rain, severe drought, high winds, excessive moisture, or other conditions that preclude satisfactory results.
3.2 SEEDING AREAS
A. Site Preparation:
1. For bare earth seeding, seed bed preparation shall not be started until all stones, boulders, debris and similar material
larger than 3 inches in diameter have been removed. The prepared surface shall be relatively free from weeds, clods,
stones, roots, sticks, rivulets, gullies, crusting and caking. The Owner's representative shall be informed in writing of
conditions detrimental to the proper and timely completion of the work. The contractor shall identify the areas that are
detrimental for seeding and consult with the Owner's representative to determine the corrective action. Seeding work is not
to proceed until the condition is either corrected or a waiver is guaranteed by the Owner's representative. Unless directed
by the Owner's representative no seeding shall occur until all soil test results have been reviewed by the Contractor and
the Owner's representative. No seeds shall be sown until the seed bed has been approved by the Owner's representative.

trees to be saved as identified on the plans.
2. All areas with slopes of 3:1 or less soil shall be compacted to 80% using a water filled roller or cultipacker. Areas
which are steeper than 3:1 shall not be compacted until after seeding. All grades shall be approved and maintained for
areas to be seeded. All mechanical equipment for soil preparation or seeding shall be as approved and shall pass parallel
to the contours unless otherwise approved. Areas shall be tilled to a depth of 6" by disking or plowing and smooth/
firmed by harrowing/ dragging. For all other areas if the grading has just been completed and the soil is loose and
friable, not eroded or crusted, the tilling step may be omitted if approved by the Owner's representative. The soils shall
be left in this scarified condition and shall not be smooth rolled. If lawn areas are seeded before the grass and forbs
mix, care shall be taken that the lawn areas are not damaged or disturbed. In case of any disturbances or damages, the
contractor shall assume responsibility and shall repair all damages and reseed. The Owner's representative reserves the
right to point out any damages done by the contractor for a period of 1 year after the work has been carried out to
ensure the visibility of such damages. Repair of these damages shall be the responsibility of the Contractor. The

work as noted is performed in complete accordance with this Section to the satisfaction of the Owner's representative, all
seeding and mulching so approved shall be accepted. If the Owner's representative determines that reseeding is necessary,
the Contractor shall begin reseeding within five working days of an oral or written request from the Owners representative
3. Tillage and site preparation shall be carried out in the same time frame as the time of seeding window. Two weeks after
firming, the seeding area shall be dragged to remove any existing live vegetation and emerging seedlings. The dragging
operation shall be performed utilizing a lightweight harrow with drawbar. The lightweight harrow shall be dragged across
the site no faster than four mph to remove emerging plants/seedlings, maximum tillage depth of one (1) inch. The area
is sown with the specified seed; the seeding area shall be dragged during the remainder of the growing season by the
specified method at no greater than two (2)-week intervals. The actual seeding shall not occur until at least three (3)
spring dragging operations have been performed. When required, this dragging requirement shall continue on two (2)-week
intervals until the specified seeding window opens and the seed is sown. All existing trees shall be protected during the
tillage operation and site preparation operation.
4. Within this seeding window, seed operations shall be performed only if the soil temperature is greater than 550 F.

Regardless of the site preparation option or plant height, during the {2} y p p seed
seeding area shall be dragged as specified above. All dragging operations are incidental to this work. No dragging
operations shall occur after the seeding. The Contractor shall notify the Owners representative at least forty-eight (48)
hours in advance of the time he/she intends to begin sowing seed and shall not proceed with such work until permission
to do so has been obtained. When delays in operations carry the work beyond the dates that are specified in the
schedule or when conditions of high winds, excessive moisture, or ice are such that satisfactory results are not likely to
be obtained at any stage of the work, the Owner's representative shall stop the work. The work shall be resumed with the
Owner's representative's approval when the desired results are likely to be obtained or when approved corrective measures
and procedures are adopted.
in B. Permanent Seed Slopes 3:1 and Greater:

1. Broad cost seeding should be done immediately after the final cultivation, rototilling, or harrowing, but before the site is
roller packed.
i h part 2. The seed shall be mixed well and divided into two equal parts. Mix each pa with an equal volume of horticultural
vermiculite or perlitie, clean sand, or other inert carrier. Start spreading the first lot of seeds in the north south direction
making regular transects. Once finished spread the second lot of seed in the east west direction. Ensure that areas
planted in this method are fully and evenly covered. Rake or chain drag the seed in and roller pack to a compaction
rate of 80% immediately after planting. Seeding depth should be between 1/2" to 3/4" in sandy soils.
3. The method and equipment used for broadcasting the seed shall be subject to approval by the client's representative.
C. Permanent Seeding slope 3:1 and less:
1. Truax dropseeder/grass drill or approved equal should be used to seed immediately after the last cultivation and roller
packing. When using a dropseeder, care shall be taken to ensure that the seed is clean and free of straw. The ground
speed of the dropseeder/ grass drill shall be 2-3 miles an hour.
2. Seeding depth shall 1/2" - 3/4" in sandy soils.
3. Care shall be taken to cover the site completely and even,y. Corners should be slightly overlapped to avoid gaps when
turning. The site shall be covered entirely once. The second time the site shall be covered at right angles to the first
pass to prevent row effect. The seed- tube windows of the seed drill shall be monitored continuously to ensure they do
not become plugged. Occluded seed -tube shall be cleaned out as soon as they become clogged.
SEEDING SPECIFICATIONS (cont.
D. Temporary Seeding:
1. The hydro -seeding applicator shall have a wcter tank equipped with a liquid level gauge calibrated to read increments not
greater than 0.2 m3 over the entire range of the tank capacity, and the gauge shall be mounted and visible to the
nozzle operator. The tank shall also be equipped with an agitation system capable of keeping all the solids in a state of
complete suspension at all times during the seeding operation.
2. Wet Application of Lime, Fertilizer and Seed. The contractor shall apply the seed, lime and fertilizer by mixing them in an
aqueous solution. The limestone, fertilizer and seed shall be added to the seeding applicator after the unit has been
completely filled with water. A minimum of 9400 L/ha of water shall be required. The contractor may choose to
incorporate the wood cellulose fiber as an iniegral part of the slurry. In the event he/she chooses to apply the wood
cellulose fiber as a part of the seed slurry, the mulch shall be added after the seed, fertilizer and lime are thoroughly
mixed in the spraying applicator. Where areas of less than 0.4 ho are involved, the seed, limestone (wood cellulose fiber
when included in slurry) and fertilizer shall be mixed together in the relative proportions specified above with not more
than 36 kg of these combined materials mixed with each 100 L of water.
3. Where the use of a chemical binder is speci"ied, the chemical binder shall be diluted in a minimum of 14,000 L/ha of
water when applied on rain wet soil; and in o minimum of 24,000 L/ha when applied on dry soil. Both the application
rate of the chemical binder and of the dilution water may be varied by the Owner's representative, in accordance with the
construction site and particular soil requirements. The limestone, fertilizer, seed, wood cellulose fiber and chemical binder
shall comprise the seeding slurry to be applied with wet application equipment as described above. The chemical binder
shall be applied at a minimum rate of 425 L/ha as determined by the Owner's representative. The wood cellulose fiber
shall be applied at the rate of 675 kg/ha. The seeding slurry shall not be applied during heavy rain fall or at
temperatures below 1'C. Following the final application, all surfaces consolidated shall not be disturbed in any manner by

E. Quantities of Material. The quantity of limestone as specified shall be applied at the rate of 3400 kg/ha. The quantity of seed
specified shall be applied at the rate specified in the chart above. Fertilizer shall be applied according to the quantities
recommended by topsoil testing results.
F. For dropseeder/drill seeding or broadcast seeding, fertilizer shall be uniformly broadcast at the rate recommended by the soil tests
prior to the seeding. Unless specified on the plans, the fertilizer shall not be incorporated into the soil. In lieu of a soil test, as
waived only by the Department and only when authorized by the Department, 400 pounds per acre of a commercial fertilizer shall
be applied in accordance with the specifications herein.
G. All areas outside of specified limits where the vegetative growth has been injuriously disturbed or destroyed by the Contractor, as
solely determined by the Owner's representative, shall be restored and seeded in accordance with these specifications by the
Contractor at his/her own expense.
H. Seeded areas shall be maintained by the Contractor until the work has received initial acceptance from the Owner's representative.
Maintenance sholl consist of the repair of areas damaged by erosion, wind, fire, and unauthorized access. The soil in such damaged
areas shall be restored to specified condition and specified grade and shall be reseeded to the satisfaction of the Owner's
representative. Initial acceptance of the seed installation shall not occur until at least four (4) weeks following completion of the
seeding operation. Acceptance of the seed installation 'oy the Owner's representative shall be based on proper site preparation,
installation, and satisfactory completion of required watering. Those areas that fail the inspection shall be reseeded at the
Contractor's expense with no additional cost to the Ooner.
3.3 MULCHING
A. Small Grain Straw. Straw Mulch shall be used for all slopes 1:3 (vertical to horizontal) or less. In 1: 3 (vertical to horizontal) or
greater, straw -coconut fiber blankets or bonded fiber matrix shall be used. Mulching shall be carried out evenly and uniformly
immediately after seeding is completed. An approved mechanical blower shall be used to apply the straw.
Straw mulch shall be applied at the rate of 4500 Ib/ac and secured by one of the following methods:
1. Crimping Method. This method of incorporating the straw into the ground shall be accomplished with the use of crimping
device that produces horizontally oriented indentation. Straw mulch shall be incorporated into the soil to a minimum
depth of 20 (50 mm). The crimping device shall be approved by the owners representative.
2. Tracking Method. This method may be used on all sites mulched with straw and shall involve the use of steel -cleat
track -type equipment drivin u an w h he cleats. Cleats
ypg p d down e slopes producing horizontally oriented indentations with #
shall be capable of incorporating the straw mulch into the soil to a minimum depth of 120 (40 mm). The equipment
used and the method of tracking shall be approved by the owner's representative
3.4 MAINTENANCE
1. Final Cleaning. Upon the completion of this section, final cleaning shall be done within the limits of the project, and
shall consist of completely cleaning the project of excess material, sweeping pavements and structures of dirt and rubbish,
and the removal of any unused material which will mar the appearance of the contract or repairing any areas as
determined by the Owner's representative as not meeting the specifications.
2. The Contractor shall maintain all seeded areas for one full year following the last seeding. All areas shall be protected
from equipment traffic and any damaged areas shall be repaired and reseeded.
3. In the first year of seeding, weeds shall be mowed back to 4"-6" tall at all times and not allowed to reach 12" at all
an time. Care should be taken not to allow the weeds to row more than f I!preventh smother of the
y g a foot to te
proposed seed. Mowing shall not be carried out when the soils or plants are wet. A fail type mower shall be used. Wood
stakes shall be placed along seed edge at 10' on center to delineate where mowing shall occur. These stakes shall be
removed after one year following planting_
4. Seeded areas shall be mown to a height of 8" before the nurse crop of Oats sets seed. Additionally seeded areas shall
be mown to a height of 8" in the first full year following seeding whenever average growth reaches 15". Care shall be
taken that any trees or shrubs that have been planted in seeded areas are not damaged. The contractor shall be
responsible for performing mowing maintenance for one full year after the last date of seeding.
5. Mowing in second growing year should be performed no more than twice a year and shall be the responsibility of the
contractor. The weeds can be mowed at a height of about one foot in the second growing season. Biennial weeds shall
be mowed when in full bloom, but before the seed set, usually in mid to late June.
6. The Contractor shall thoroughly water newly seeded areas immediately upon installation at the rated of 25,000 gallons per
acre, unless indicated on the plans or directed by the Owner's representative. A second thorough watering shall occur two
(2) weeks after seed installation, unless indicated on the plans or directed by the Owners representative. The Contractor
shall avoid creating rills and furrows as a -esult of watering. The Contractor shall be responsible for repairing and
reseeding any rills or furrows caused by over watering at the Contractor's own expense.
7. The Owner's representative reserves the right to decide whether an area needs to be reseeded and shall need the written
approval of the Owner's representative for any reseeding done on the project. The application rates will be based on the
stand of grass and forbs, severity of erosion and condition or growth of grass and forbs as described. Fall seeded areas
shall be given a second step seeding and mulching, as required, the following spring from May 15 to June 15. The
following shall be used as a guide for second step application:
8. For areas with less than 50 percent stand or subject to severe erosion, apply the complete amount of seed and mulch
(straw mulch) as specified in the original seeding. For areas with over 50 percent of grass and forbs and slight to
moderate erosion, apply one half the original seed. If erosion is a problem apply one half the original wood fiber mulch.
The third step seeding and mulching shall consist of spot application on areas not showing a satisfactory stand after the
second step application. The quantity of material will be determined on the same basis as for the second step application.
