Keep Your Dirt!
Muddy water leaving your construction site is a red flag that is sure to get the attention of inspectors. Avoid work delays and fines. Keep your dirt on-site by implementing effective best management practices (BMPs).
  • Install erosion and sediment controls properly at the beginning of construction
  • Clear the smallest area possible in which to complete your work and keep as much of the existing vegetation as possible
  • Stabilize disturbed soil areas immediately after final grading
  • Divert storm water away from your disturbed areas
  • Slow down storm water runoff before it leaves your site
  • Install gravel entrance to minimize tracking of dirt onto roadways
  • Maintain BMPs throughout your project.
