Erosion Control Requirements during Construction

The applicant and property owner are required to use best management practices (BMPs) on all construction projects no matter how big or small to prevent sediment from leaving the construction site.

Some of the most common BMPs that are required on most projects are Silt Fence, Inlet Protection and Vehicle Tracking Pads. Please submit an erosion control plan or include BMPs on your grading plan and include them with your Grading and Excavation permit application. Failure to do so will cause a delay in the issuance of a permit. Please refer to the following guide for additional information and ideas:
