Prior DOB to Approval:

  • DEP Stormwater Construction Permit or
  • DEP Determination of Non-Jurisdiction prior to DOB approval and

Prior to DOB Sign-Off:

  • DEP Stormwater Maintenance Permit or
  • NY State DEP Conservation Notice of Termination prior to DOB sign-off.

Note that this requirement is applicable to all of New York City, not just work in an MS4 Area.
