VEGETATION PLAN
1. All of the disturbed area will be covered with dirt and or gravel
as needed to prepare for seeding or future use within 21 days of
completion of any phase of grading.
2. The surfaces to be seeded will be roughed and tilled to prepare
a seed bed.
3. The following Lime and fertilizer mix will be used to prepare
the soil for the seeds:
Agricultural lime 2,000#/acre
Fertilizer 1,000#/acre
4. The following seed specifications will be used paying special
attention to the date of seeding and seeds required for that
season:

5. Surface mulch shall be applied after seeding to provide a means
of controlling runoff and erosion in disturbed areas. Straw
mulch shall be applied at the rate of 1 ton per acre. Straw
should be dry, unchopped, unweathered and free of weeds.
Wheat or oat straw is preferred and can be spread by machine
or hand. Straw must be tacked down to avoid loss by wind.
6. After a vegetation growth is established, fertilization will
continue as needed until a sod layer is established. 11-wa�
7. Decorative landscaping may be added later as a beautification
project in stable areas, but only in areas not subject to erosion
and heavy runoff.
8. In areas where shade is dominating the mixture should
substitute Orchard Grass and or Blue Grass for Fescue.
9. Temporary seeding should be performed using 40 pounds of
German Millet or Rye (grain) per acre and the fertilizer and lime
mix above.
10. Top dressing should be performed within 6 months if a vigorous
growth has net been established.

Planning Rough slope surfaces are preferred because they aid the establishment of vegeta.
Considerations tion, improve water infiltration, and decrease runoff velocity. Graded areas with
smooth, hard surfaces may be initially attractive, but such surfaces increase the
potential for erosion. A rough, loose soil surface gives a mulching effect that
protects lime, fertilizer, and seed. Nicks in the surface are cooler and provide
more favorable moisture conditions than hard, smooth surfaces; this aids seed
germination. '

grooves perpendicular to the slope. The
slope face should not be back -bladed
during the final grading operation (source:
Va SWCC).
There are different methods for achieving a roughened soil surface on a slope,
and the selection of an appropriate method depends upon the type of slope.
Roughening methods include stair -step grading, grooving, (Figure 6.03a). and
tracking. Factors to be considered in choosing a method are slope steepness,
mowing requirements, and whether the slope is formed by cutting or filling.

Design Criteria No formal design is required.
Construction CUT SLOPE ROUGHENINGFOR AREAS NOT TO BE MOWED
Specifications Stair -step grade or groove cut slopes with a gradient steeper than 3:1 (Figures
6.03b and 6.03c).
Use stair -step grading on any erodible material soft enough to be ripped with a
bulldozer. Slopes consisting of soft rock with some subsoil are particularly
suited to stair -step grading.
Make the vertical cut distance less than the horizontal distance, and slightly
slope the horizontal position of the "step" in toward the vertical wall.
Do not make individual vertical cuts more than 2 feet in soft materials or more
than 3 feet in rocky materials.
Grooving uses machinery to create a series of ridges and depressions that run
across the slope (on the contour).
Groove using any appropriate implement that can be safely operated on the
slope, such as disks, tillers, spring harrows, or the teeth on a front-end loader
bucket. Do not make such grooves less than inches deep nor more than 15 in-
ches apart.
FILL SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED
Place fill slopes with a gradient steeper than 3:1 in lifts not to exceed 9 inches,
and make sure each lift is properly compacted Ensure that the face of the slope
consists of loose, uncompacted fill 4 to 6 inches deep. Use grooving, as
described above, to roughen the face of the slopes, if necessary.
Do not blade or scrape the final slope face.
CUTS, FILLS, AND GRADED AREAS THAT WILL BE MOWED
Make mowed slopes no steeper than 3:1.
Roughen these areas to shallow grooves by normal tilling, disking, harrowing,
or use of cultipacker-seeder. Make the final pass of any such tillage implement
on the contour.
Make grooves formed by such implements close together (less than 10 inches)
and not less than I inch deep.
Excessive roughness is undesirable where mowing is phMed,
ROUGHEMING WITH TRACKED MACHINERY
Limit roughening with tracked machinery to sandy soils to avoid undue com-
paction of. the soil surface. Tracking is generally not as effective a's the other
roughening methods described. .
Operate tracked machinery up and down the slope to leave horizontal depres-
sions in the'soll. Do not back -blade during the final grading operation.

Seeding Immediately seed and mulch roughened areas to. obtain optimum
seed germination and growth.
Maintenance
Periodically check the seeded slopes for rills and washes. Fill these areas slight-
ly above the original grade, then reseed and mulch as soon as possible.
