BALED NAY OR STRAW EROSION CHECKS
GENERAL NOTtS:
1. Erosion cdntrol measures shall be incorporated in the sequence of
construction to prc c. --t sediment laden water from leaving the site.
2. All hay bale and silt fence erosion and sedimentation checks shall be placed
prior to beginning work as per the plass and a:, per app*opriate detail
specification sheets.
3. Natural vegtation shall be retained wher-wer feasib:c up to f� ; scheduled
start of a construction activity in the area. where pt` ssible, clearing shall
immediately precede construction acti-ify.
4. Eresion control measures shall, whe-e applicable, inccrporate at Last the
following procedures detailed on this drawing:
a. Temporary barrier of hayhales to prevent sediment laden water from
entering the pond.
b. Provide tLmporary slope crosion control where required.
C. Fill and grading shall be treated with slope stabilization seeding or
ground _over and hay mulch upon completion.
>. No siltation shall- be allowed in the wetlands on site and no erosion of Vie
bank edge shall be allowed urrder any circumstances.
6. Wherever hay -bale or sil fence filters are used, they shall be maintained in
good working condition until ground cover is reestablished. Silt fence shall
be periodically cleaned as necessary to assure proper and effective
functioning, Hay bales shall also be replaced similarly as necessary to
provide adequate function.
7. The downhill toc-of slope of all stockpiled sot'= shall be protected by staked
hay bales or silt fence.
Is. No stockpi!c::g of soils shall be in walan d areas or within 30' of wetland -s
shown.
9. All soils disharbed during construction shall be restored to grade, seeded and
mulched with hay or straw until growth is established.
lU. Soil stockpiles shall be sha cd and seeded with LZ iemporar; cove: as per
seeding specifc_atio ns or mulched if grading is to be delayed owr wirier
11. All work in regulated areas shall be performed under the supervision of the
Project Landscape Architect or Engineer.
12. If any questions arise regarding erosion and sedimcniat_on control Treasures,
the Project Landscape Architect or Engineer shall be consulted immediately.
DESIGN GUIDEL.IN—ES FOR STRAVI 13ALE BARRLrEPS
S::ect Flow Applications
s. Bales shall be placed_ in a single row, lengthwise on the
contour, with ends of adjacent bales tinlltly abutting one
another.
2. All bales shall be either wire -bound or string -tied. Straw
bales shall be installed so that bindings are oriented
around the sides rather than along the tops and bottoms of
tc.e bales (ir, order to prevent deterioration of the bindings).
3. T't:e barrier shall be entrenched and backfilled. A trench
shall be excavatel the width of a bale and the length of the
proposed barrier to a minimum depth of 4 inches. After the
bales are staked and chinked, the excavated soil shall be
backfilled against the barrier. Backfill soil shall conform
to the ground level on the downhill side and shall be built
to 4 inches against the uphill side of the barrier=
4. Eac#r§$a' shall be securely anchored by at least two s-ttsltgs- ,
or rebars d r I v •hrough the bale. The first stake in each
bale shall L. n toward the previously laid bale to force
the bales tc_E Stakes or re -bars shall be driven deep
enough into tt..r q:v::nd to securely anchor the bales.
5. The gaps batwet r voles shall be chinked (filled by wedgi-ng)_�
with straw to pie-ent water from escaping between the bales_
Loose straw scattered over the area im•nediately uphill from
a straw bale barrier tends to increase barrier efficiency).
i
6. Zraspection Shall be frequent and repair or replacement shall
be made promptly as needed.
7. Straw bale barriers shall be removed when they have served
their usefulness, but not before the upslope areas have been
permanently stablizied.
Channel flow Applications
I. Bales shall be placed in a single row, lengthwise, oriented
perpendicular to the contour, with ends of adjacent bales
tightly abutting one another.
2. The remaining steps for installing a straw bale barrier for
s^eet flow applications apply here, with the following addition.
3. T1.e barrier shall be extended to such a length that the
bottoms of the end bales are higher in elevation than the top
of the lowest middle bale to assure that sediment laden runoff
will flew either through or over the barrier but not around it.
