Stormwater Permits, Ordinances and Floodplain

  • Stormwater quality requirements are mandated from the Federal government in the Clean Water Act. 
  • Stormwater quantity requirements are mandated by the Federal Emergency Management Agency. 

To meet these requirements, the State issues general stormwater permits for municipalities.  To receive State permits, the municipalities issue ordinances to adhere to the State requirements. In this section some of the State permits and Town Ordinances required for Stormwater Management are provided.
