Applications & Forms

Required permits or forms depend on activity type (construction dewatering, industrial discharge, or sewer connection). The publicly available city pages and municipal code do not publish a single consolidated industrial discharge form on the cited pages; applicants should contact the listed departments to request specific permits or application packets.

  • Construction-related stormwater permits: see City building and grading permit procedures; specialized State permits (e.g., NPDES General Permit) may also apply and are obtained through state portals.
  • Sewer connection and sewer service applications: obtain rates and connection procedures from the regional sewer agency or the city's utility billing office.

Reporting, Inspections & Compliance Steps

Follow these action steps to report, comply, or seek relief:

  • Report immediate spills or illicit discharges to the City Public Works emergency contact as soon as possible.
  • Preserve evidence: take photos, note time and location, and keep records of any communication with officials.
  • Implement corrective actions requested by inspectors and submit required documentation within stated deadlines.
