MAINTENANCE OF GRASS SWALE:
MAINTENANCE OF GRASSED SWALES INVOLVES GROOMING THE VEGETATION AND OCCASIONALLY REMOVING TRASH. IF NATIVE
VEGETATION IS USED INSTEAD OF TURF, VEGETATION HAS TO BE MOWED ONLY SEASONALLY TO RETARD THE GROWTH OF WOODY
VEGETATION. ROUTINE MOWING IS REQUIRED IF TURF GRASSES ARE USED. THE RECOMMENDATION IS THAT GRASS BE CUT NO LOWER THAN
2 INCHES. IN ADDITION, THE GRASS SHOULD BE ALLOWED TO GROW TO THE MAXIMUM HEIGHT CONSISTENT WITH THE SPECIES AND
AESTHETIC REQUIREMENTS. SWALES POPULATED WITH WETLAND VEGETATION OR OTHER LOW -MAINTENANCE GROUND COVER DO NOT
REQUIRE MOWING OF THE CHANNEL. THE FREQUENCY OF TRASH REMOVAL DEPENDS ON THE LOCATION AND ATTRACTIVENESS OF THE
SWALE AS A DISPOSAL SITE.
EXCESSIVE SEDIMENT SHOULD NOT ACCUMULATE IF EROSION IS CONTROLLED ADEQUATELY UPSTREAM.
HOWEVER, IF EXCESSIVE SILTATION OCCURS, THE SEDIMENT MUST BE REMOVED PERIODICALLY (NO LESS THAN ONCE ANNUALLY).
SEDIMENT THAT ACCUMULATES IN THE SWALE MAY BE PRONE TO RESUSPENSION DURING LARGE STORM EVENTS AND CAN KILL THE GRASS.
SEDIMENT SHOULD BE REMOVED WHEN IT REACHES A DEPTH OF 1 INCHES OR WHEN IT COVERS THE GRASS.
ADDITIONAL ANNUAL MAINTENANCE ACTIVITIES ARE AS FOLLOWS:
REPAIR EROSION AND REGRADE THE SWALE TO ENSURE THAT RUNOFF FLOWS EVENLY IN A
THIN SHEET THROUGH THE SWALE.
REVEGETATE THE SWALE AS NEEDED TO MAINTAIN A DENSE GROWTH.

Soil preparation
Test soil to determine the exact requirements for lime and fertilizer. Soil tests may be conducted by the State soil testing lab or a reputable
commercial laboratory. Information on free soil testing is available from the Agronomic Division of the North Carolina Department of Agriculture
or the Agricultural Extension Service.
Where sodding must be planned without soil tests the following soil amendments may be sufficient:
• Pulverized agricultural limestone at a rate of 2 tons/acre (100 Ib/1,000 ft2)
• Fertilizer at a rate of 1,000 lb/acre (25 Ib/1,000 ft2) of 10-10-10 in fall or 5-10-10 in spring. Equivalent nutrients may be applied with other
fertilizer formulations.
These amendments should be spread evenly over the area, and incorporated into the top 4-8 inches of soil by disking, harrowing, or other
effective means.
Prior to laying sod, clear the soil surface of trash, debris, roots, branches, stones, and clods larger than 2 inches in diameter. Fill or level low
spots in order to avoid standing water. Rake or harrow the site to achieve a smooth and level final grade.Complete soil preparation by rolling or
cultipacking to firm the soil. Avoid using heavy equipment on the area, particularly when the soil is wet, as this may cause excessive compaction,
and make it difficult for the sod to take root.
Sod installation
1. Moistening the sod after it is unrolled helps maintain its viability. Store it in the shade during installation.
2. Rake the soil surface to break the crust just before laying sod. During the summer, lightly irrigate the soil, immediately before laying the sod to
cool the soil, reduce root burning, and dieback.
3. Do not sod on gravel, frozen soils, or soils that have been treated recently with sterilants or herbicides.
4. Lay the first row of sod in a straight line with subsequent rows placed paralled to and butting tightly against each other. Stagger strips in a
brick -like pattern. Be sure that the sod is not streached or overlapped and that all joints are butted tightly to prevent voids. Use a knife or sharp
spade to trim and fit irregularly shaped areas.
5. Install strips of sod with their longest dimension perpendicular to the slope. On slopes 3:1 or greater, or wherever erosion may be a problem,
secure sod with pegs or staples.
6. As sodding of clearly defined areas is completed, roll sod to provide firm contact between roots and soil.
7. After rolling, irrigate until the soil is wet 4 inches below the sod.
8. Keep sodded areas moist to a depth of 4 inches until the grass takes root. This can be determined by gently tugging on the sod —resistance
indicates that rooting has occurred.
9. Mowing should not be attempted until the sod is firmly rooted, usually 2-3 weeks.
MAINTENANCE
AFTER the first week, water as necessary to maintain adequate moisture in the root zone and prevent dormancy of the sod.Do not remove more
than one-third of the shoot in any mowing. Grass height should be maintained between 2 and 3 inches unless otherwise specified.
After the first growing season, established sod requires fertilization, and may also require lime.

CHANNEL
INSTALLATION
DETAIL
1. Prepare soil before installing rolled
erosion control products (RECPs),
including any necessary application of
lime, fertilizer, and seed.
2. Begin at the top of the channel by
anchoring the RECPs in a 6"(15cm)
deep X 6"(15cm) wide trench with
approximately 12"(30cm) of RECPs
extended beyond the up -slope portion
of the trench. Use ShoreMax mat at the
channel/culvert outlet as supplemental
scour protection as needed. Anchor the
RECPs with a row of staples/stakes
approximately 12"(30cm) apart in the
bottom of the trench. Backfill and
compact the trench after stapling. Apply
seed to the compacted soil and fold the
remaining 12"(30cm) portion of RECPs
back over the seed and compacted soil.
Secure RECPs over compacted soil
with a row of staples/stakes spaced
approximately 12" apart across the
width of the RECPs.
3. Roll center RECPs in direction of water
flow in bottom of channel. RECPs will
unroll with appropriate side against the
soil surface. All RECPs must be
securely fastened to soil surface by
placing staples/stakes in appropriate
locations as shown in the staple pattern
guide.
4. Place consecutive RECPs end -over -end
(Shingle style) with a 4"-6" overlap. Use
a double row of staples staggered 4"
apart and 4" on center to secure
RECPs.
5. Full length edge of RECPs at top of side
slopes must be anchored with a row of
staples/stakes approximately 12"(30cm)
apart in a 6"(15cm) deep X 6"(15cm)
wide trench. Backfill and compact the
trench after stapling.
6. Adjacent RECPs must be overlapped
approximately 2"-5" (5-12.5cm)
(Depending on RECPs type) and
stapled.
7. In high flow channel applications a
staple check slot is recommended at 30
to 40 foot (9 -12m) intervals. Use a
double row of staples staggered
4"(10cm) apart and 4"(10cm) on center
over entire width of the channel.
8. The terminal end of the RECPs must be
anchored with a row of staples/stakes
approximately 12" (30cm) apart in a
6"(15cm) deep X 6"(15cm) wide trench.
Backfill and compact the trench after
stapling.
