Construction

Avoid fines and work stoppages, and protect the waterways your community depends on, by implementing and maintaining these EPA construction site stormwater best management practices (BMPs).

Protect Natural Features

  • Minimize Clearing.
  • Minimize the amount of disturbed soil.
  • Identify and protect areas where existing vegetation, such as trees, will not be disturbed by construction activity.
  • Protect streams, stream buffers, wild woodlands, wetlands, or other sensitive areas from any disturbance or construction activity by fencing or other clear markings.

Construction Phasing

  • Sequence construction activities so the landscape is not disturbed for long periods of time.
  • Limit grading to small areas.
  • Install key sediment control practices before site grading begins.
  • Schedule site stabilization, such as landscaping, to be completed immediately after the land has been graded to its final contour.

Vegetative Buffers

  • Protect and install vegetative buffers along waterbodies to slow and filter stormwater runoff.
  • Inspect and maintain buffer areas regularly to ensure effectiveness.

Site Stabilization

  • Vegetate, mulch, or otherwise stabilize all exposed areas as soon as land alterations have been completed.

Storm Drain Inlet Protection

  • Use rock or other appropriate material to cover the storm drain inlet to filter out trash and debris.
  • Make sure the rock size is appropriate (usually 1 to 2 inches in diameter).
  • Inspect and maintain all inlet protection devices and erosion controls on a regular schedule, and immediately after every rain storm.

Dirt Stockpiles

  • Cover or seed all dirt stockpiles to protect them from precipitation.
  • Install control berms around the base of stockpiles to prevent the material from migrating.

Slopes

  • Rough grade or terrace slopes.
  • Break up long slopes with sediment barriers, or under drain, or divert stormwater away from slopes.

Construction Entrances

  • Install construction entrances with measures to remove mud and dirt from the tires of construction vehicles before they enter a paved roadway.
  • Appropriately mark the entrance so all visiting parties are aware of its location.
  • Properly size the entrance and its sediment controls for all anticipated vehicles.
  • Regularly maintain the entrance to ensure its consistent effectiveness.

Silt Fencing

  • Inspect and maintain silt fences on a regular schedule, and immediately after every rain storm.
  • Make sure the bottom 6" of the silt fence is buried in the ground and install the fence perpendicular to the slope.
  • Securely attach the material to the stakes.
  • Don’t place silt fences in the middle of a waterway or use them as a check dam.
  • Make sure stormwater is not flowing around the silt fence.
