[MS4 Training] New MS4 General Permit Plan Review Requirements

In this webinar, Environmental Services Project Manager Nancy Cho discusses the upcoming new construction stormwater and MS4 draft general permits. The new permits mean significant changes to the plan review process for new development and redevelopment, including:

  • stormwater pollution prevention plans (SWPPPs) will need to include additional information
  • MS4s will need to update their ordinances and standards
  • new post-construction requirements will require additional technical review of stormwater quantity and quality
