Any development or redevelopment project (public or private) will require a Stormwater Permit if:

  1. It can drain to a City-owned sewer system
  2. It disturbs 20,000 sf or more of soil, or adds 5,000sf or more of new impervious area

View Chapter 19.1 of Title 15 of the Rules of the City of New York for the most up-to-date list of project exclusions and definitions.

To apply for Stormwater Permits you must submit an application using our Stormwater Permitting and Tracking System or “SWPTS.”
