PERMANENT SEEDING SPECIFICATION
1. All disturbed areas shall be dressed to typical sections and plowed to a depth of 5 inches.
The top 2 Inches shall be pulverized to provide uniform seedbed. NOTE: Line should be applied
with necessary equipment to give uniform distribution of these materials. The hand -bucket
method is not acceptable. Lime and fertilizer should be Incorporated Into the sell prior to
2. The following are rates and kinds of these materials to be applied
KIliQ RATES.
Abruzzi Rye 50 lbs.

10-20-20 Fertilizer 500 lbs.
Agricultural Limestone 4000 lbs.
3. Seeded area shall be cultipacked to firth seedbed and to cover seed.
4. Grain straw shall be applied over seeded areas as mulch. No bare ground shall be visible
in the mulched area if proper applications is achieved. Thick dumps of straw are not
Pam as uniform coverage is expected. Straws shall be applied at a minimum of 4000
5. The mulched area shall be tacked with liquid asphalt sufficient too hold straw in place
where directed by Engineer.
6. Ditch treatment shall be used in areas where steep grades could cause ditch erosion. Use
of jute mesh, excelsior matting, or fiberglass roving Is acceptable. ditch treatment should be
installed before mulching operation.
7. Builder Is to provide a Permanent ground cover sufficient to restrain erosion on such
exposed areas within /5 working days or 90 calendar days, whichever is shorter, after
completion of construction or development

Fertilizer shall be 10-20-20 analysis. Upon written approval of the Engineer, a different
analysis of fertilizer may be used provided the 1-2-2 ratio is maintained and the rate of
application adjusted to provide the some amount of plant food as a 10-20-20 analysis.
Fertilizer Topdressing:
Fertilizer used for topdressing on all roadway areas except elopes 2.1 and steeper shall
be 10-20-20 written approval of the Engineer, a different analysis of fertilizer may be
used provided grade and shall be applied at the rate of 500 pounds per acre (560kg per
hectare). Upon the 1-2-2 ratio Is maintained and the rate of application adjusted to
provide the some amount of plant food as 10-20-20 analysis.
Fertilizer used for topdressing on slopes 2*1 and steeper and waste and borrow areas
shall be 16-8-8 grade and shall be applied at the rate of 500 pounds per acre (560 kg
per hectare). Upon written approval of the Engineer, a different analysis of fertilizer
may be used provided the 2-1-1 ratio is maintained and the rate of application
adjusted to provide the same amount of plant food as 16-8-8 analysis.
Crknping Straw Mulch:
Crimping will be required on these project adjacent to any section of roadway where
traffic is to be maintained or allowed during constriction. In areas within six feet (2
meters) of the edge of pavement, straw is to be crimped and the Immediately tacked
with asphalt tack.
Crimping of straw In lieu of asphalt tack will be allowed on this project subject to the
following conditions:
All areas seeded and mulched shall be crimped and/or tacked with asphalt as directed
by the Engineer.
Crimping will be limited to slopes 4.1 or flatter unless the Contractor can demonstrate
to the Engineer that the steeper slopes can be negotiated without altering the typical
section.
Straw mulch to be of sufficient length and quality to withstand the crimping operation
and provide adequate ground cover.
Crimping equipment Including power source shall be subject to the approval of the
Engineer providing that maximum spacing of crimper blades shall not exceed 8 inches
(200 mm).
MAINTENANCE SCHEDULE
1. All erosion and sediment control practices will be checked for stability and operation
following every storm event, but In no case less than once every week. Any repairs or cleaning
necessary to maintain erosion and sediment control practices shell be completed Immediately.
2 All seeded areas will be refertilized, reseeded as necessary, and mulched according to the
Seeding Schedule.
Seeding and Mulching:
The kinds of seed and fertilizer, and the rates of application of seed, ferilizer, and limestone,
shdl be as stated below. During periods of overlapping dates, the kind of seed to be used
shill be determined by the Engineer. All rates per acre (kilograms per hectare.)
