Sediment Bale Barrier 

 

Code References

  • "For sites with less than 5 acres disturbed at one time, filter fences, straw bales or equivalent control measures shall be placed along all side slope and down slope sides of the site. (Reference: Section 290-7.2.e-5 of the City Code of Ordinances).
  • "Perimeter erosion control measures shall be placed within 24 hours of beginning excavating." (Reference: Section Comm 21.125(1)(a) of the Wisconsin Administrative Code).
  • "Erosion control measures shall be placed along down slope areas and along side slope areas as required to prevent or reduce erosion where erosion during construction will result in a loss of soil to waters of the state, public sewer inlets or off-site." (Reference: Section Comm 21.125(1)(a) of the Wisconsin Administrative Code).

Quick Tips

  • Sediment bale barriers shall be inspected weekly at minimum and within 24 hours after a precipitation event of 0.5 inches or greater.  Damaged or decomposing bales and any undercutting or bypassing of flow around the bales shall be repaired immediately upon notice.
  • Sediment deposits shall be properly disposed of when the deposits have accumulated to 1/2 the height of the sediment bale barriers.
  • Sediment bale barriers shall not be placed perpendicular to flow in swales, ditches, streams, or any other place where concentrated runoff exists.
  • Sediment bale barriers shall not be placed where the up slope gradient is greater than 50% (2:1 slope).
  • The ends of sediment bale barriers ends shall extend up slope to prevent water from flowing around the barrier.
  • Sediment bale barriers shall be entrenched and backfilled.
  • The holes between bales shall be filled by wedging straw or hay.
  • At least two wood stakes, steel posts, or rebar shall be driven through each bale to securely anchor the barrier.  The first stake shall be driven toward the previously installed bale to force the bales together.
  • Bales shall be oriented so that the bindings are around the sides of the bales (rather than along the tops and bottoms of the bales) when installed.
