Class II Environmental Permit

The Class II Permit is required for the construction, installation and/or alteration of any outfall or overflow system discharging into any water body of Miami-Dade County

If the applicant indicates that they cannot reasonably contain the whole storm event on-site, the County will then allow a discharge to a body of water.

The Class II permit will require treatment of the stormwater runoff before discharge to the water body to ensure water quality is provided.

Before you start work:

• Zoning approval from a local municipality or Miami-Dade County (if you are in unincorporated Miami-Dade) is required prior to construction activity
• Depending on the type, size and location of development and/or construction, a Class I or IV permit might be needed, as well as a
  • District Right-of-Way permit, and a
  • Surface Water Management General Permit for a development that contains at least 10 acres of total area, or at least 2 acres of impervious surface issued by the Water Control Section pursuant to authority delegated by the South Florida Water Management District (SFWMD)
  • Environmental Resource Permit (ERP) if required by SFWMD or the Florida Department of Environmental Protection

Depending on your situation, you may need one or more of the above-mentioned permits. Additionally, there may be instances when a permit that is not listed here is required. We encourage you to contact the Water Control Section to discuss your case or to receive additional information.

• It takes approximately 30 days to process the Class II Permit
• The Class II Permit fees are listed in the Fee Schedule
• The Class II Permit is valid for two years and it is renewable
