Good
• Inspect and maintain silt fences after each rainstorm.
• Make sure the bottom of the silt fence is buried in the ground.
• 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.
Construction Phasing
Good
• Sequence construction activities so that the soil is not
exposed for long periods of time.
• Schedule or limit grading to small areas.
• Install key sediment control practices before site grading
begins.
• Schedule site stabilization activities, such as landscaping,
to be completed immediately after the land has been
graded to its final contour.
Vegetative Buffers
Good
• Protect and install vegetative buffers along waterbodies to
slow and filter stormwater runoff.
• Maintain buffers by mowing or replanting periodically to
ensure their effectiveness.

Construction Entrances
Good
• Remove mud and dirt from the tires of construction vehicles
before they enter a paved roadway.
• Properly size entrance BMPs for all anticipated vehicles.
• Make sure that the construction entrance does not become
buried in soil.
Slopes
Good
• Rough grade or terrace slopes.
• Break up long slopes with sediment barriers, or under
drain, or divert stormwater away from slopes.
Dirt Stockpiles
Site Stabilization
Good
• Vegetate, mulch, or otherwise stabilize all exposed areas as
soon as land alterations have been completed.
Storm Drain Inlet Protection
Good
• Cover or seed all dirt stockpiles.
Good
• 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).
• If you use inlet filters, maintain them regularly.

Good
• Minimize clearing.
• Minimize the amount of exposed soil.
Silt Fencing
• 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 otherwise clearly marking these areas.
