For code provisions and regulatory text consult the City Code and the Traffic/Transportation pages for current procedures and any permit requirements. [1][2]

  • Responsible departments: Public Works - Transportation/Traffic Operations; Naperville Police Department; Community Development for permit review.
  • Typical subject matter: right-of-way permits, traffic signal/ITS attachments, data privacy or camera registration, and contractor installation standards.
  • Primary official pages and code sections should be consulted for binding requirements and application processes. [1][2][3]
Always confirm the latest ordinance text with the municipal code before planning installations.
