• Minimize compaction of soil by limiting heavy
  equipment use to specific areas.
• Restore any damaged areas.

11

• Protect streams, stream buffers, wild woodlands,
  wetlands, or other sensitive areas for,
  disturbance by fencing or otherwise clearly
  marking these areas.

12
Construction Phasing

• Sequence construction activities so that the soil
  is not exposed for long periods of time.
• Limit grading to small areas.

Install key sediment control practices before

Schedule site stabilization activities, such as
landscaping, to be completed immediately after
the land has been graded to its final contour.
22
Plant Vegetative Buffers

• Protect and install vegetative buffers along
  water bodies to slow and filter storm water
  runoff.
• Maintain buffers by replanting if needed.

23
Site Stabilization

• Apply temporary stabilization to rough-graded
  areas.
• Plant, mulch or otherwise stabilize all exposed
  areas as soon as land alterations have been
  completed.

Plan Construction Entrances

• Utilize construction exits to minimize vehicle

• Use properly sized entrances for all anticipated
  vehicles.
• Use geotextile beneath entrance along with 2 to
  3 gravel.
